SUMMAFtY OF THE INVENTION
The fiber planting layer of the present invention is improved to have exce:Llent adhesion strength to a substrate such as a surface treated steel sheet and high flexibility.
Therefore, when the fiber planted substrate is processed (for example, pressed or for.rned) , the planting layer is not broken, cracked or separated.
The electrostatically fiber planted steel sheet of the present inven.tion can be used as a raw material for construction material products such as ducts for the prevention of dripping of condensed dew and panels for the prevention of dripping of condensed dew, kitchen utensils, electric appliances, office equipment, car parts, toys, containers, casings and the like by using a surface treated steel sheet such as a commercially available galvanized steel sheet as a substrate and planting fibers in the stei=_l sheet electrostatically.
The present j_nvention also provides a fiber planted steel sheet by directly forming a fiber plating layer of an aqueous adhesive composition for planting fibers essentially composed of an aqueousemulsionresin having a specific glass transition temperature of -40 to 40 ~C on the substrate without using an aqueous polyurethane resin containing a polar solvent, for example, a disperse solvent other than water such as N
methylpyrrolidoneandelectrostatically planting short f ibers in this planting layer as well as a process for producing the same at a low cost.
The emulsior. resir.L which is the main ingredient of the aqueous adhesive composition for planting fibers forming the fiber planting layer of the present invention is mainly an acrylic emulsion or ethylene-vinyl acetate emulsion resin.
Other emulsion resins such as a synthetic rubber emulsion typified by styrene-butadiene, vinylchloride -basedemulsion, vinylidene chloride-based emulsion, alkyd resin-based emulsion, polyester-based emulsion, phenolic resin-based emulsion and copo:_ymer emulsions thereof may be used and the glass transition temperature of the main ingredient resin is limited to -40 to 40 C.
As for other cornponents of the aqueous adhesive composition for planting fibers, 0 to 20 parts by weight of an aqueous pigment dispersion, 0 to 3 parts by weight of a defoamer, 0 to 5 parts by weight of a pH modifier, 0 to 25 parts by weight of a crosslinking agent, 0 to 10 pats by weight of a thickener, 0 to 20 parts by weight of a water-soluble resin and an emulsion resin having a glass transition temperature outside the above range are suitably mixed together based on 100 parts by weight of the above emulsion resin as required.
The plantinq operation is carried out in such a manner that the fiber pla.nting voltage is controlled to 10 to 80 kV
or the viscosity of the aqueous adhesive composition for planting fibers is adjusted to 200 to 20,000 cps/25 - C at the time of planting fibers to ensure that the roots of the short fibers are situate!d at an intermediate position of the fiber planting layer and the short fibers do not contact the surface of the surface treated steel sheet through the fiber planting layer.
Since the fiber planting layer made from the aqueous adhesive composition for planting fibers used in the electrostatically fiber planted steel sheet of the present invention has exce.llent adhesion strength to a substrate such as a steel sheet and high flexibility, it is not broken, cracked or separated when the fiber planted substrate is processed (pressed or ~ormed) . I t also has excellent fiber adhesion that the planted short fibers do not fall off at the time of processing.
In the present invention, a fiber planting layer having high flexibility and excellent adhesion to a substrate can be formed on a su.bstrate such as a steel sheet by coating a special aqueous adhesive composition forplanting fibers on the surface of asurfacetreatedsteelsheet. Therefore, the coating layer is not brokeri, cracked or separated when the obtained fiber planted steel sheet product is processed such as drawn or bent and the planted short fibers do not fall off at the time of processing.
Since the electrostatically fiber planted steel sheet product planted with fi:bers using the aqueous adhesive composition for plantinq fibers of the present invention has excellent in not only processing but also the prevention of dripping of condensed dew, incombustibility and corrosion resistance, the fiber planted steel sheet product of the present invention can be used as a raw material for construction material products such as ducts for the prevention of dripping of condensed dew a::id panels for the prevention of dripping of condensed dew, kitchen utensils, electric appliances, office equipment, auto cars parts, toys, containers and casings.
Further, in the production of conventional electrostatically fiber planted steel sheets, a steel sheet is subjected to an electrostatic fiber planting treatment. In the production of the electrostatically fiber planted steel sheet of the present invention, a rolled surface treated steel sheet can be unrolled, straightened out, subjectect to an electrostatic fiber plariting treatment continuously and then wound up, it has an effect specific to the present invention that it can be slit into a thin belt and supplied as a raw material for rolled products such as a spiral tube.
Therefore, it is a first object of the present invention to make it possible to use a surface treated steel sheet such as a rolled galvanized steel sheet (including products treated with a chromate or coated with an organic or inorganic composite film containing no chromium) as a substrate for an electrostatically fiber planted steel sheet.
It is a second object of the present invention to provide an electrostatica=_ly fiber planted steel sheet produced by directly forming a fiber planting layer on a surface treated steel sheet as a:>ubst.rate without a primer of a polyester synthetic resin containing an anticorrosive pigment or the like and electrostatically planting short fibers in this planting layer as well as a process for producing the same at a low cost.
It is a third. object of the present invention to provide an electrosta.tica].ly fiber planted steel sheet produced by directly forming a fiber planting layer of an aqueous adhesive composition for plantirrg fibers which is essentially composed of a specified aqueous emulsion resin on a substrate such as a surface treated steel sheet and electrostatically planting short fibers in tr. is planting layer as well as a process for producing the same at a low cost.
The above ob lects and advantages of the present invention will become more apparent from the following description when taken in conjunction with the accompanying drawings.
BRIEF DESCRIPTION OF THE ATTACHED DRAWINGS
Fig. 1 is a side view of the cross section of an embodiment of a fiber planted steel sheet product obtained by the process of the preserit inventi.on; and Fig. 2 is a partially enlarged sectional view for explaining the fiber planted state of the fiber planted steel sheet product: shovin in Fig. 1.
DESCRIPTION OF THE PREFERRED EMBODIMENTS
The surface treated steel sheet used in the present invention is a hot-dipped galvanized steel sheet, alloy-based hot-dipped steel sheet, electrically galvanized steel sheet, alloy electroplated steel sheet, precoated steel sheet or the like. The galvanized steel sheet includes products treated with a chromate or coated with an organic or inorganic composite film containing no chromium. The short fibers to be electrostatically planted in the fiber planting layer are chemical fibers such as regenerated fibers, semi-synthetic fibers or synthetic fibers, or natural fibers suchasvegetable fibers, animal fibers, carbon fibers or glass fibers and may be either organic fiber.s or inorganic fibers.
An acrylic emulsion of the aqueous adhesive composition for plantingfibersusedintheelectrostaticallyfiberplanted steel sheet of the present invention is obtained by emulsion copolymerizing a monomer such as methyl methacrylate, ethyl methacrylate, isopropyl methacrylate, n-butyl methacrylate, isobutyl methacrylate, n-hexyl methacrylate, 2-ethylhexyl methacrylate, lauryl methacrylate, methacrylic acid, hydroxypropyl methacrylate, glycidyl methacrylate, acrylic acid, methyl acrylate, ethyl acrylate, isopropyl acrylate, n-butyl acrylate, 2-eth.ylhexyl acrylate, hydroxypropyl acrylate, hydroxybutyl acrylate, acrylic amide, N-methylol acrylamide, diacetone acrylamide, diacetone methacrylamide, styrene, vinyl toluene, acrylonitrile, methacrylonitrile or vinyl acetate in accordarice with a conventionally known method.
The ethylene-vinyl acetate-based emulsion is obtained by conventiorially known emulsion copolymerization or melting an ethylene-vinyl acetate resin which is a thermoplastic resin by heating and emulsifyirig it in water by a known method. Other emulsions are obtained by the known method.
Besides these main ingredients, an aqueous coloring pigment dispersion [example of trade product: Aqua Fine Color of Dainichi ;3eika Kogyosha Co.], defoamer [Defoamer of Sun Nopco Co.], pH modifier such as a tertiary amine, aqueous crosslinking agent for the functional group of an emulsion resin [oxazoline pendant resin, ethylene imine compound, carbodiimide compound, :melamine resin, epoxy resin, amino resin, block isocyanate compound, metal salt compound, etc. ], thickener [example of ti-ade product: Primal of Rohm and Harse Co.], and water-soluble resin [alkyd resin-based, acrylic resin-based, styrene resin-based, epoxy resin-based, cellulose resin-based, etc.] are added as required.
Stated more specifically, as for the composition of the aqueous adhesive composition for planting fibers, 0 to 20 parts by weight of an aqueous coloring pigment dispersion, 0 to 3 parts by weiqht of' a defoamer, 0 to 5 parts by weight of a pH
modifier, 0 to 25 parts by weight of a crosslinking agent, 0 to 10 parts by weight of a thickener, 0 to 20 parts by weight of a water-soluble resin and an emulsion resin having a glass transition temperature outside the specified range are suitably mixed together based on 100 parts by weight of the emulsion resin having a specific transition temperature of -40 to 40 - C. To blend thern, they are stirred with a disperser for 5 to 10 minutes to adjust a pH value to 7.0 to 9.0 in the end.
Although bubbles are formed right after production, the aqueous adhesive composition is used 2 to 3 hours after production.
The emulsion resiri having a specific transition temperature of -40 to 40 - C is mainly an acrylic emulsion resin or ethylene-vinyl ace'tate-based emulsion resin. Other emulsion resin such as a styrene-butadiene synthetic rubber-based emulsion, viriyl chloride-based emulsion, vinylidene chloride-based emulsion, alkyd resin-based emulsion, polyester-based erlulsi.on, phenolic resin-based emulsion or copolymer emulsiorr thereof may be used.
In the present irivention, an aqueous resin which is an emulsion resin hav:-ng a specific transition temperature of -40 to 40 - C is used. This emulsion resin aqueous resin generally has an organic resin particle diameter of 0.114-yn or more, enables organic resin particles having a diameter of 0.01 to 0. 1/{!.m to suspend in water and can keep the particles suspending in water stably by ionizing the particles or adding an emulsifier. Since this emulsion resin aqueous resin is an anionic self-emulsified organic resin and has a hydrophilic group which :Ls an ionic functional group in the interior of its resin particle, the resin itself can suspend in water. As for the physical properties of the coating film, as resin particles emulsion suspending in water form a coating film through fusion polymerization, the coating film has excellent adhesion.
As for the characteristic properties of the aqueous adhesive composition for planting fibers used in the electrostatically fiber planted steel sheet of the present invention, since the composition is water-soluble, it has such an advantage that 3-t is not necessary to use an organic solvent having high contamination properties. A coating layer having flexibility c:an be formed by applying an aqueous solution of this adhesive composition to a substrate with a roll coater, spray or applicator and the thickness of the coating layer after drying is about 10 to 50.4ft. Examples are provided to further illustrate the present invention.
(Example 1) Fig. 1 is a sectional view showing the structure of an electrostatically fiber planted steel sheet obtained by the production process of the present invention. In Fig. 1, reference numeral 1 is a surface treated steel sheet as a substrate, 2 an electrostatically fiber planting layer formed on the surface of the surface treated steel sheet 1 and coated with an adhesive composition, and 3 short fibers planted in the electrostatically fiber planting layer 2 by electrostatic fiber planting operation. In this Example, organic short fibers are plante~d as the short fibers 3.
To produce this electrostatically fiber planted steel sheet, an aqueous adhesive compositionfor planting fibers was first obtained by adding 1 part by weight of a defoamer, 0.5 part by weight of diethanolamine (pH modifier) and 5 parts by weight of an aqueous epoxy resin to 100 parts by weight of an acrylic emulsion (soli(i content of 55 %) having a glass transition temperature of -20 0 C obtained from methyl methacrylate and 2-ethy7Lhexyl acrylate as main ingredients and stirring them wit.h a d:isperser for 10 minutes.
This aqueous adhesive composition for planting fibers having a sol:id coritent: of 55 %, a viscosity of 2, 000 cps/25 - C
and a pH of 8.0 was coated on a surface treated steel sheet with a reverse ro:.l coater in a wet state to 50_4,11q and organic short fibers of nylon. 66 were planted immediately in the obtained coating laye:r using an electrostatic fiber planting apparatus (of Mesac C'.o.) at a voltage of 30 kV to form an electrostatically fibeir planted layer.
In the above fiber planting operation, the above electrostatically fiber planted layer is such as shown in the enlarged sectional view of Fig. 2 that the voltage of the electrostatic fiber planting apparatus had to be controlled or the viscosity of the adhesive conlposition had to be adjusted to ensure that the roots 3a of the organic short fibers 3 were situated at an intermediate portion of the electrostatically fiber planting la'Yer 2 and that the organic short fibers 3 did not contact the surface la of the surface treated steel sheet 1 as a substrate through the electrostatically fiber planting layer 2. This is because if the roots 3a of the planted organic short fibers 3 contacted the surface la of the surface treated steel sheet 1 through t:he electrostatically fiber planting layer 2, the electrostatically fiber planting layer 2 would be easily separated frorn the surface treated steel sheet 1 at the time of processing or use. After the organic short fibers 3 were planted as described above, the coating was forcedly dried in a di:rer at a temperature of 150 to 200 ~C for 3 minutes to obtain an electrostatically fiber planted steel sheet product. A r-oll coater or applicator may be used to coat the adhesive composit:ion on the surface treated steel sheet 1. The electrostatically fiber planted steel sheet shown in Fig. 1 is obtained by this operation.
(Example 2) As an alternative method different from that of Example 1, to produce an electrostatically fiber planted steel sheet, 15 parts by weight of an acrylic emtilsion resin (solid content of 50 %) having a glass transition temperature of 40 - C obtained by copolymerizing methyl methacrylate, n-butyl acrylate and hydroxypropyl acrylate, 0.5 part by weight of a defoamer, 1 part by weight of ammonia (pH modifier) and 3 parts by weight of aqueous block :Lsocyanate were added to 100 parts by weight of an ethylene-vinyl acetate emulsion resin (solid content of 55 %) having a glass transition temperature of -18 OC and stirred with a disperser for 10 minutes to obtain an aqueous adhesive composit:ion for planting fibers.
This aqueous adhesive composition for planting fibers havirig a solid corrtent: of 52 %, a viscosity of 5, 000 cps/25 0 C
and a pH of 3.5 were coated on a surface treated steel sheet with a reverse ro:Ll coater in a wet state to 60.411t and organic short fibers. of nylon 66 were planted immediately using an electrostatic fiber planting apparatus (of Mesac Co.) at a voltage of 40 kV to for=m an electrostatically fiber planted layer. Also in this Example 2, the same care as in Example 1 must be taken to plant fibers.
The results of a durability test made on the fiber planted steel sheet products obtained in the above Examples 1 and 2 in accordance with JIS-K-5400 (general coating test standard) and a scratch test not specified in JIS and conducted additionally on these products are shown in Table 1.

The electrostatically fiber planted steel sheet of the present inven.tion can be used as a raw material for construction material products such as ducts for the prevention of dripping of condensed dew and panels for the prevention of dripping of condensed dew, kitchen utensils, electric appliances, office equipment, car parts, toys, containers, casings and the like by using a surface treated steel sheet such as a commercially available galvanized steel sheet as a substrate and planting fibers in the stei=_l sheet electrostatically.
The present j_nvention also provides a fiber planted steel sheet by directly forming a fiber plating layer of an aqueous adhesive composition for planting fibers essentially composed of an aqueousemulsionresin having a specific glass transition temperature of -40 to 40 ~C on the substrate without using an aqueous polyurethane resin containing a polar solvent, for example, a disperse solvent other than water such as N
methylpyrrolidoneandelectrostatically planting short f ibers in this planting layer as well as a process for producing the same at a low cost.
The emulsior. resir.L which is the main ingredient of the aqueous adhesive composition for planting fibers forming the fiber planting layer of the present invention is mainly an acrylic emulsion or ethylene-vinyl acetate emulsion resin.
Other emulsion resins such as a synthetic rubber emulsion typified by styrene-butadiene, vinylchloride -basedemulsion, vinylidene chloride-based emulsion, alkyd resin-based emulsion, polyester-based emulsion, phenolic resin-based emulsion and copo:_ymer emulsions thereof may be used and the glass transition temperature of the main ingredient resin is limited to -40 to 40 C.
As for other cornponents of the aqueous adhesive composition for planting fibers, 0 to 20 parts by weight of an aqueous pigment dispersion, 0 to 3 parts by weight of a defoamer, 0 to 5 parts by weight of a pH modifier, 0 to 25 parts by weight of a crosslinking agent, 0 to 10 pats by weight of a thickener, 0 to 20 parts by weight of a water-soluble resin and an emulsion resin having a glass transition temperature outside the above range are suitably mixed together based on 100 parts by weight of the above emulsion resin as required.
The plantinq operation is carried out in such a manner that the fiber pla.nting voltage is controlled to 10 to 80 kV
or the viscosity of the aqueous adhesive composition for planting fibers is adjusted to 200 to 20,000 cps/25 - C at the time of planting fibers to ensure that the roots of the short fibers are situate!d at an intermediate position of the fiber planting layer and the short fibers do not contact the surface of the surface treated steel sheet through the fiber planting layer.
Since the fiber planting layer made from the aqueous adhesive composition for planting fibers used in the electrostatically fiber planted steel sheet of the present invention has exce.llent adhesion strength to a substrate such as a steel sheet and high flexibility, it is not broken, cracked or separated when the fiber planted substrate is processed (pressed or ~ormed) . I t also has excellent fiber adhesion that the planted short fibers do not fall off at the time of processing.
In the present invention, a fiber planting layer having high flexibility and excellent adhesion to a substrate can be formed on a su.bstrate such as a steel sheet by coating a special aqueous adhesive composition forplanting fibers on the surface of asurfacetreatedsteelsheet. Therefore, the coating layer is not brokeri, cracked or separated when the obtained fiber planted steel sheet product is processed such as drawn or bent and the planted short fibers do not fall off at the time of processing.
Since the electrostatically fiber planted steel sheet product planted with fi:bers using the aqueous adhesive composition for plantinq fibers of the present invention has excellent in not only processing but also the prevention of dripping of condensed dew, incombustibility and corrosion resistance, the fiber planted steel sheet product of the present invention can be used as a raw material for construction material products such as ducts for the prevention of dripping of condensed dew a::id panels for the prevention of dripping of condensed dew, kitchen utensils, electric appliances, office equipment, auto cars parts, toys, containers and casings.
Further, in the production of conventional electrostatically fiber planted steel sheets, a steel sheet is subjected to an electrostatic fiber planting treatment. In the production of the electrostatically fiber planted steel sheet of the present invention, a rolled surface treated steel sheet can be unrolled, straightened out, subjectect to an electrostatic fiber plariting treatment continuously and then wound up, it has an effect specific to the present invention that it can be slit into a thin belt and supplied as a raw material for rolled products such as a spiral tube.
Therefore, it is a first object of the present invention to make it possible to use a surface treated steel sheet such as a rolled galvanized steel sheet (including products treated with a chromate or coated with an organic or inorganic composite film containing no chromium) as a substrate for an electrostatically fiber planted steel sheet.
It is a second object of the present invention to provide an electrostatica=_ly fiber planted steel sheet produced by directly forming a fiber planting layer on a surface treated steel sheet as a:>ubst.rate without a primer of a polyester synthetic resin containing an anticorrosive pigment or the like and electrostatically planting short fibers in this planting layer as well as a process for producing the same at a low cost.
It is a third. object of the present invention to provide an electrosta.tica].ly fiber planted steel sheet produced by directly forming a fiber planting layer of an aqueous adhesive composition for plantirrg fibers which is essentially composed of a specified aqueous emulsion resin on a substrate such as a surface treated steel sheet and electrostatically planting short fibers in tr. is planting layer as well as a process for producing the same at a low cost.
The above ob lects and advantages of the present invention will become more apparent from the following description when taken in conjunction with the accompanying drawings.
BRIEF DESCRIPTION OF THE ATTACHED DRAWINGS
Fig. 1 is a side view of the cross section of an embodiment of a fiber planted steel sheet product obtained by the process of the preserit inventi.on; and Fig. 2 is a partially enlarged sectional view for explaining the fiber planted state of the fiber planted steel sheet product: shovin in Fig. 1.
DESCRIPTION OF THE PREFERRED EMBODIMENTS
The surface treated steel sheet used in the present invention is a hot-dipped galvanized steel sheet, alloy-based hot-dipped steel sheet, electrically galvanized steel sheet, alloy electroplated steel sheet, precoated steel sheet or the like. The galvanized steel sheet includes products treated with a chromate or coated with an organic or inorganic composite film containing no chromium. The short fibers to be electrostatically planted in the fiber planting layer are chemical fibers such as regenerated fibers, semi-synthetic fibers or synthetic fibers, or natural fibers suchasvegetable fibers, animal fibers, carbon fibers or glass fibers and may be either organic fiber.s or inorganic fibers.
An acrylic emulsion of the aqueous adhesive composition for plantingfibersusedintheelectrostaticallyfiberplanted steel sheet of the present invention is obtained by emulsion copolymerizing a monomer such as methyl methacrylate, ethyl methacrylate, isopropyl methacrylate, n-butyl methacrylate, isobutyl methacrylate, n-hexyl methacrylate, 2-ethylhexyl methacrylate, lauryl methacrylate, methacrylic acid, hydroxypropyl methacrylate, glycidyl methacrylate, acrylic acid, methyl acrylate, ethyl acrylate, isopropyl acrylate, n-butyl acrylate, 2-eth.ylhexyl acrylate, hydroxypropyl acrylate, hydroxybutyl acrylate, acrylic amide, N-methylol acrylamide, diacetone acrylamide, diacetone methacrylamide, styrene, vinyl toluene, acrylonitrile, methacrylonitrile or vinyl acetate in accordarice with a conventionally known method.
The ethylene-vinyl acetate-based emulsion is obtained by conventiorially known emulsion copolymerization or melting an ethylene-vinyl acetate resin which is a thermoplastic resin by heating and emulsifyirig it in water by a known method. Other emulsions are obtained by the known method.
Besides these main ingredients, an aqueous coloring pigment dispersion [example of trade product: Aqua Fine Color of Dainichi ;3eika Kogyosha Co.], defoamer [Defoamer of Sun Nopco Co.], pH modifier such as a tertiary amine, aqueous crosslinking agent for the functional group of an emulsion resin [oxazoline pendant resin, ethylene imine compound, carbodiimide compound, :melamine resin, epoxy resin, amino resin, block isocyanate compound, metal salt compound, etc. ], thickener [example of ti-ade product: Primal of Rohm and Harse Co.], and water-soluble resin [alkyd resin-based, acrylic resin-based, styrene resin-based, epoxy resin-based, cellulose resin-based, etc.] are added as required.
Stated more specifically, as for the composition of the aqueous adhesive composition for planting fibers, 0 to 20 parts by weight of an aqueous coloring pigment dispersion, 0 to 3 parts by weiqht of' a defoamer, 0 to 5 parts by weight of a pH
modifier, 0 to 25 parts by weight of a crosslinking agent, 0 to 10 parts by weight of a thickener, 0 to 20 parts by weight of a water-soluble resin and an emulsion resin having a glass transition temperature outside the specified range are suitably mixed together based on 100 parts by weight of the emulsion resin having a specific transition temperature of -40 to 40 - C. To blend thern, they are stirred with a disperser for 5 to 10 minutes to adjust a pH value to 7.0 to 9.0 in the end.
Although bubbles are formed right after production, the aqueous adhesive composition is used 2 to 3 hours after production.
The emulsion resiri having a specific transition temperature of -40 to 40 - C is mainly an acrylic emulsion resin or ethylene-vinyl ace'tate-based emulsion resin. Other emulsion resin such as a styrene-butadiene synthetic rubber-based emulsion, viriyl chloride-based emulsion, vinylidene chloride-based emulsion, alkyd resin-based emulsion, polyester-based erlulsi.on, phenolic resin-based emulsion or copolymer emulsiorr thereof may be used.
In the present irivention, an aqueous resin which is an emulsion resin hav:-ng a specific transition temperature of -40 to 40 - C is used. This emulsion resin aqueous resin generally has an organic resin particle diameter of 0.114-yn or more, enables organic resin particles having a diameter of 0.01 to 0. 1/{!.m to suspend in water and can keep the particles suspending in water stably by ionizing the particles or adding an emulsifier. Since this emulsion resin aqueous resin is an anionic self-emulsified organic resin and has a hydrophilic group which :Ls an ionic functional group in the interior of its resin particle, the resin itself can suspend in water. As for the physical properties of the coating film, as resin particles emulsion suspending in water form a coating film through fusion polymerization, the coating film has excellent adhesion.
As for the characteristic properties of the aqueous adhesive composition for planting fibers used in the electrostatically fiber planted steel sheet of the present invention, since the composition is water-soluble, it has such an advantage that 3-t is not necessary to use an organic solvent having high contamination properties. A coating layer having flexibility c:an be formed by applying an aqueous solution of this adhesive composition to a substrate with a roll coater, spray or applicator and the thickness of the coating layer after drying is about 10 to 50.4ft. Examples are provided to further illustrate the present invention.
(Example 1) Fig. 1 is a sectional view showing the structure of an electrostatically fiber planted steel sheet obtained by the production process of the present invention. In Fig. 1, reference numeral 1 is a surface treated steel sheet as a substrate, 2 an electrostatically fiber planting layer formed on the surface of the surface treated steel sheet 1 and coated with an adhesive composition, and 3 short fibers planted in the electrostatically fiber planting layer 2 by electrostatic fiber planting operation. In this Example, organic short fibers are plante~d as the short fibers 3.
To produce this electrostatically fiber planted steel sheet, an aqueous adhesive compositionfor planting fibers was first obtained by adding 1 part by weight of a defoamer, 0.5 part by weight of diethanolamine (pH modifier) and 5 parts by weight of an aqueous epoxy resin to 100 parts by weight of an acrylic emulsion (soli(i content of 55 %) having a glass transition temperature of -20 0 C obtained from methyl methacrylate and 2-ethy7Lhexyl acrylate as main ingredients and stirring them wit.h a d:isperser for 10 minutes.
This aqueous adhesive composition for planting fibers having a sol:id coritent: of 55 %, a viscosity of 2, 000 cps/25 - C
and a pH of 8.0 was coated on a surface treated steel sheet with a reverse ro:.l coater in a wet state to 50_4,11q and organic short fibers of nylon. 66 were planted immediately in the obtained coating laye:r using an electrostatic fiber planting apparatus (of Mesac C'.o.) at a voltage of 30 kV to form an electrostatically fibeir planted layer.
In the above fiber planting operation, the above electrostatically fiber planted layer is such as shown in the enlarged sectional view of Fig. 2 that the voltage of the electrostatic fiber planting apparatus had to be controlled or the viscosity of the adhesive conlposition had to be adjusted to ensure that the roots 3a of the organic short fibers 3 were situated at an intermediate portion of the electrostatically fiber planting la'Yer 2 and that the organic short fibers 3 did not contact the surface la of the surface treated steel sheet 1 as a substrate through the electrostatically fiber planting layer 2. This is because if the roots 3a of the planted organic short fibers 3 contacted the surface la of the surface treated steel sheet 1 through t:he electrostatically fiber planting layer 2, the electrostatically fiber planting layer 2 would be easily separated frorn the surface treated steel sheet 1 at the time of processing or use. After the organic short fibers 3 were planted as described above, the coating was forcedly dried in a di:rer at a temperature of 150 to 200 ~C for 3 minutes to obtain an electrostatically fiber planted steel sheet product. A r-oll coater or applicator may be used to coat the adhesive composit:ion on the surface treated steel sheet 1. The electrostatically fiber planted steel sheet shown in Fig. 1 is obtained by this operation.
(Example 2) As an alternative method different from that of Example 1, to produce an electrostatically fiber planted steel sheet, 15 parts by weight of an acrylic emtilsion resin (solid content of 50 %) having a glass transition temperature of 40 - C obtained by copolymerizing methyl methacrylate, n-butyl acrylate and hydroxypropyl acrylate, 0.5 part by weight of a defoamer, 1 part by weight of ammonia (pH modifier) and 3 parts by weight of aqueous block :Lsocyanate were added to 100 parts by weight of an ethylene-vinyl acetate emulsion resin (solid content of 55 %) having a glass transition temperature of -18 OC and stirred with a disperser for 10 minutes to obtain an aqueous adhesive composit:ion for planting fibers.
This aqueous adhesive composition for planting fibers havirig a solid corrtent: of 52 %, a viscosity of 5, 000 cps/25 0 C
and a pH of 3.5 were coated on a surface treated steel sheet with a reverse ro:Ll coater in a wet state to 60.411t and organic short fibers. of nylon 66 were planted immediately using an electrostatic fiber planting apparatus (of Mesac Co.) at a voltage of 40 kV to for=m an electrostatically fiber planted layer. Also in this Example 2, the same care as in Example 1 must be taken to plant fibers.
The results of a durability test made on the fiber planted steel sheet products obtained in the above Examples 1 and 2 in accordance with JIS-K-5400 (general coating test standard) and a scratch test not specified in JIS and conducted additionally on these products are shown in Table 1.
