Description

Floor panel

Technical field

The present invention relates to a kind of floor panel, comprise support plate, on support plate, add one and use layer, this use floor has a pattern that is divided into different patterns district ornamentally, wherein, ornamental pattern prevents wearing and tearing by means of wear-resisting particle, and, use the surface of layer that a kind of embossment shape structure that comprises depression and protuberance is arranged, wherein depression is swelled other pattern area overlappings with decoration pattern with the pattern area overlapping of regulation.

Background technology

In order to imitate wood surface, ceramic surface or rock surface, known so-called laminate is made floor panel by them.Laminate has a use layer that is made of two-layer at least stacked paper usually, and it is placed on the support plate of timber system.As timber, density or high density fiberboard, particieboard etc. in the employing.In most of the cases be pressed into large-area plate, then be divided into the polylith veneer, they further are processed as floor panel.Floor panel is rectangle normally.One of paper that uses layer is printed with the figure line pattern on the surface that will imitate.But the paper of printing has low wearability usually, and thereby must be added with the so-called tectal paper of abrasion resistant particles and protect by transparent, prevent wearing and tearing.Adopt the particle of powdered, they for example are made up of aluminium oxide for this reason, and this is a kind ofly to make the raw material of frosted by it and other materials.On this cover layer, stamp out a kind of embossment shape structure with compression tool.Therefore use layer to form by a vision imitation layer and a sense of touch imitation layer on surface.In other words, feeling all right than the figure line that reappears the material that will imitate of people given on the surface.

The paper that is added with pattern is used resin impregnated after applying pattern, for example phenolic resins or melmac or mixed form.For example in resin, can contain for the additive that improves processability with in order to reduce the filler of cost of material.Cover layer adds resin equally.After this two layers of paper in hot pressing the fusing by resin be connected to each other and be connected with support plate.

Use the paper existing problems and the costliness of resin dipping.Existing problems are because print the paper generation length of pattern and the growth of width.Because paper is with the resin wetted of fusion and associated growth, so the size of paper can change behind dipping.This depends on some influence factors, as the quality of air humidity, paper, the quality of resin etc.Must use compression tool stamping surface structure on melaminated paper behind the dipping.Yet this surface texture is often because the changeability of paper size can not be overlapping exactly with the etching pattern.Therefore, need be divided into two steps for the paper of processing a kind of dipping.Length and width that the first step must reduce ornamental printed article also are printed on the paper with the minification of regulation.The second step paper also increases with resin wetted, and this moment, paper should match with the size of compression tool at the growth state.This method is because the changeability that paper increases thereby be inaccurate.

In addition, adopt the paper of resin dipping to need a so-called counter pull, that is to say, one deck paper must be placed in the downside of support plate, to set up and the balance that constitutes those paper that use layer at the support plate upside.If there is not counter pull, after ply of paper and support plate hot pressing, can produce the gross distortion of floor panel.

The complexity of resin and paper conversion has improved the percent defective when producing the ornamental printed article of dipping.Less than or the paper that surpasses norminal size can not be used in laminated product because pattern and embossing are not overlapping.

In addition, suppress the energy and the equipment cost height of resiniferous paper and support plate,, be in the same place with in this way these layers being connected to each other with molten resin because must in the layer that these will connect, add high temperature and heat.

Another shortcoming is the arrangement of abrasion resistant particles.Known two kinds of alternative plans add particle.Scheme 1: particle is in the tectal paper.During producing covering paper, in the paper fiber, sneak into particle.This covering paper is followed impregnating resin.Scheme 2: covering paper does not have particle.Replace particle is blended in the resin, but cover paper only at side resin/particle mixture coating, and the agranular resinous coat of tectal opposite side.In order to impress embossment shape structure, that side that covering paper is coated with no particulate resin is towards compression tool, to prevent that the compression tool surface is by hard abrasion of particles.

The shortcoming of two kinds of schemes of mentioned this is that the surface of embossment shape structure is made of agranular material until certain degree of depth.This agranular material quick-wearing very when floor panel uses.Only when exposing that one deck that wherein is distributed with abrasion resistant particles by wearing and tearing, just delay wearing and tearing.Certainly, the embossment shape structure on surface goes to pot this moment.

Summary of the invention

The objective of the invention is to create a kind of floor panel, it makes the decoration pattern district and that relevant surface texture is arranged is accurately overlapping, wherein, floor panel provide wear-resisting embossment shape structure the surface and can convenient and production economically.

By the present invention is that to reach the measure that this purpose takes be that decoration pattern covers with enamelled coating; The depression of embossment shape structure causes by a kind of chemicals that reacts with lacquer; And wear-resisting particle is inserted in the enamelled coating.

The decoration pattern of japanning can be used as prefabrication and for example is applied on paper or the film, and is attached thereto for the producing zone pressing plate.In order to connect, compare with being connected of timber plate with the paper that is used for impregnating resin, need lower pressure and temperature just much of that.Because floor panel need not to carry out resin dipping, so can simplify the rolling of the compacting of laminate or laminate.Can exempt firing equipment fully according to the method for attachment between support plate and the prefabrication.Owing to the few distortion of avoiding floor panel of heat that adds.Therefore can cancel counter pull.In addition, figure line pattern can be printed under the situation of not considering dimensional contraction.Consequently simplified the imitation on reproduction surface, because the increasing step that reduces step and then increase owing to paper when implementing to print can be saved.Because cancelled the punching press on paper surface, thus can generation and the mutually positioning relevant problem of pattern with surface texture, and reach pattern district accurately overlapping of surface texture and figure line pattern.For example can on stamping surface, imitate the minor issue of timber by touch feeling in this way, and also can in a darker layer, form figure line pattern exactly by same position.This pattern can see through transparent lacquer and see.The impression of this sense of touch and vision is coordinated with each other and overlapping exactly on the place.Wood surface, ceramic surface, rock surface etc. have been realized imitating better in this way.

Use the embossment shape structure of layer to constitute by enamelled coating.Wear-resisting distribution of particles is in enamelled coating and the surface that always reaches lacquer.Therefore, between the surface of figure line pattern and embossment shape structure, do not exist do not have particle, can be very the zone of quick-wearing.So, when floor surface uses, produce the wear-resisting effect that reaches by wear-resisting particle immediately.Described embossment shape body structure surface is resisted the abrasiveness load particularly well.

Simply, decoration pattern and enamelled coating are located on the prefabricated facing paper, and facing paper is connected with support plate at the finished product state of floor panel.Different with it, also can establish decorating film and replace facing paper.For example it can stretch with its advantage of plastic decorating film.Because it can coat this specific character better, and the three-dimensional cover layer that can for example be used as the seamed edge shape.

The facing paper of japanning advantageously sticks with glue agent and is placed on the support plate.Any suitable physical bond or the adhesive of chemical reaction can be used as adhesive.Also can use for example in form for placing the alite paste of the two-side film membrane between facing paper and the support plate.This adhesive can be coated in before extruding on paper or the film.

Valuably, the facing paper of japanning partly coats at two opposed seamed edges formation seamed edges of support plate at least.The common machining of the seamed edge of support plate.The lumber fibre that exposes support plate timber.Dry timber thereby can absorb small amount of moisture and expand.The intrusion of moisture in timber prevented in whole or portion's coating by the seamed edge after will processing.By the arrangement of the use layer formed of facing paper of japanning, preferably after passing through the seamed edge place seamed edge corner cut of milling, support plate carries out.Here, facing paper stretches out from the corner cut seamed edge that will add layer.Push facing paper then and bond with support plate.Facing paper can or be cut out the length into needs, or shortens the size that requires after bonding.

Because the floor panel surface has concaveconvex structure, so the seamed edge of two panel butt joints certainly can be not superimposed each other congruently.The seamed edge height of floorboard panel changes in the peak of surface relief shape structure and the scope between the minimum point.In other words, the trend of floorboard panel seamed edge is irregular waveform.This trend produces during the machining of floor panel seamed edge.The profile that embossment shape structure is had in that plane that seamed edge this moves towards to change with seamed edge is processed therein is corresponding.

At confined state, by prior art, the darker subregion of the floorboard panel seamed edge adjacent panel seamed edge that may recline is in the zone of higher position.Therefore, stretch out and ruined danger is arranged from floor surface in Gao Wei seamed edge district.They damage because of bump easily.For preventing this destruction, the support plate of the floor panel of being advised on that side of using layer, has the seamed edge of corner cut rightly at its outward flange.This can prevent that seamed edge from peeling off.This seamed edge is not too responsive, because form a kind of depression in the seaming zone of adjacent floor panel, and these are in the seamed edge of putting than deep-seated and prevent to be hit and to wear and tear.

Simply, two opposed corner cut seamed edges of support plate are coated with self-adhering type decorating film layer.Do following advantage like this: on the support plate that for example is shaped as rectangle, two opposed corner cut seamed edges can be with using layer to coat fully.Being coated on the process technology of all the other two seamed edges is pretty troublesome, because use layer to exist than being used to coat the area that needed summary is Duoed in the zone at each angle.Use the unnecessary part of layer must coat front or rear excision at each angle of rectangle floor panel.

Perhaps, the seamed edge protection of being advised of passing through to coat floor panel can reach by adding self-adhering type decorating film layer.This has simplified processing.For this reason, first seamed edge must at first coat and use layer.They for example with milling cutter processing, use a layer part of stretching out so that remove in the end then.Obtain to add a regular surface of decorating film layer thus.

Should mention also that for the sake of completeness can process does not have decorating film tack, that must settle by other adhesive that is suitable for yet.This decorating film needn't contain abrasion resistant particles, because the indentation inward below the floor surface that processes of the seamed edge of corner cut, and thereby suffers slight wearing and tearing.

Described coating can exceed the seamed edge of corner cut, is the edge coating of floor panel.Therefore make floor panel also have bigger part can prevent the moisture intrusion through the seamed edge of processing.Even the seamed edge of support plate has groove and tenon profile, paired opposed seamed edge also can be all or part of with using layer to coat.The cost of coating fully of tenon profile is high.The tenon profile until or almost coat to tenon ground and channel profile on the free-ended coating of cell wall, fairly simple on production technology because use layer only must bend to the seamed edge of corner cut.Further crooked, for example around the upside of tenon profile or bend in the groove of channel profile, cost all can develop skill.

The sealed interlocking profile of shape that the seamed edge of support plate can have band to fall to cut portion, they prevent in the floor panel plane along perpendicular to the direction of interlocking profile floor panel being drawn back each other at the laying state.Equally, the seamed edge of support plate also can have traditional poor and tenon profile that must add the glue connection.

Coating has the meaning of particular importance for the floor that the regulation laying pattern is arranged, herringbone pattern for example, and it is made up of batten (Holzriegel).Main so far production can have a kind of floor panel of pattern of a plurality of battens, the floor panel that for example has the hull bottom outward appearance.Laying pattern as herringbone pattern, can be made by big floor panel, because the seam between the panel moves towards to disturb the outward appearance of herringbone pattern.In addition, the batten that is in floorboard panel edge only becomes the part pattern.The batten section that is shaped on pattern in edge must make up by abutting in exactly on the adjacent floor panel during laying, and makes two to have the batten section completion of pattern to become a complete batten.Here must be noted that at seam crossing has pattern accurately, offsets mutually to avoid former those batten sections that should constitute a batten jointly.

A kind of scheme of laying this class pattern is, is substituted in the pattern of a plurality of battens on the big floor panel, and batten one by one is designed to little floor panel.Each floor panel becomes single batten pattern.Therefore laying pattern no longer includes any pattern.Replace it, laying pattern constitutes by the batten of imitation one by one, and they press arranged in patterns arbitrarily as original batten.

This laying is the measure of batten Counterfeit Item one by one, has increased the share of seam in the floor.On the panel of large tracts of land floor, be modelled as the seam of printing seam so far, present then be the seam of reality.Therefore, floor panel is more little, and the seamed edge after the processing of protection floor panel is important more.Because the higher seam share of ratio of fritter floor panel for example can be invaded more moisture than the floor that constitutes with the large tracts of land panel in support plate when cleaning.But, by coating the seamed edge of little floor panel as mentioned above, can fully prevent the seam suction.

Can settle a ply of paper or thin layer at the downside of support plate, be used for the measure that waterproof or conduct suppress foot-operated sound.Described layer can be connected with the support plate downside on point type ground.Can save comprehensive connection a kind of as connection counter pull layer on support plate.

The specific embodiment

Fig. 1 represents two

floor panels

1 and 2 by interlocking of the present invention.Each

floor panel

1 or 2 has complementary interlocking profile at opposed seamed edge, so the profile of a seamed edge of floor panel matches each other with the profile of opposed seamed edge, feasiblely always can fix a similar floor panel on a floor panel of having laid.Therefore floor panel 1 is being established a channel profile (not shown) on the seamed edge of tenon profile 15, and floor panel 2 has a tenon profile (not shown) opposed to each other with its channel profile 14.

This two

floors panel

1 and 2 has a support plate 3 or 4, settles at their upside and uses

layer

5 or 6.

For the structure of using

layer

5 or 6 is described, Fig. 2 has schematically illustrated and has partly used layer.In view of the above, use layer that paper 7 is arranged, it is printed with ornamental figure line pattern 8, and it can be called the facing paper 7 that is provided with the figure line.Figure line pattern 8 is divided into different pattern districts 9 and 10.In order to prevent the pattern wearing and tearing, it is coated with 11 layers in transparent lacquer.The thickness of the thickness of enamelled coating 11 and paper 7 is expression not in scale in Fig. 2.Lacquer 11 is transparent and is mixed with abrasion resistant particles 12 in order to improve wearability.Particle 12 reaches the surface of lacquer always.In addition, there is a kind of surface relief shape structure 13 on the lacquer surface, it exactly with paper 7 on figure line pattern 8 coupling.The depression of surface relief shape structure 13 and protuberance are overlapping with the

pattern district

9 or 10 of figure line pattern 8 regulations respectively.The depression of surface relief shape structure 13 causes by the chemicals that applies before the coat of paint, and it is in japanning 11 backs and lacquer reaction.Can see the dark position of embossment shape structure 13 (depression 13a) in Fig. 2, it is with a thin enamelled coating protection, and can see that surface relief shape structure 13 is in the zone of higher position (protuberance 13b), and they are protected with thicker enamelled coating.The pattern district 9 of position 13a that surface relief shape structure is dark and figure line pattern 8 is overlapping.Replenish the impression of sense of touch and vision in this way, and a kind of good especially imitation that causes floor surface.Depression in enamelled coating 11 can reach at most prints paper 7.This depression does not have protective paint layer.These depressions preferably should have little area, thereby make them prevent massif wearing and tearing on every side effectively.

The use layer of pressing Fig. 2 is prefabricated.In order to produce

floor panel

1 or 2, prefabricated

use layer

5 or 6 is placed on support plate 3 or 4.

Press Fig. 1 and 3,

floor panel

1 and 2 support plates 3 that will be made up of timber and 4 downside are placed on the ground U that will lay, on for example a kind of basis of the soft foot-operated sound of inhibition.

Floor panel

1 and 2 support plate 3 and 4 have a corner cut at the seamed edge place of upside.The seamed edge corner cut constitutes by the radius R 1 and the R2 of milling in this example.Radius R 1 usefulness of support plate 3 uses layer 5 to coat.Support plate 4 radius Rs 2 usefulness of adjacent floor panel 2 use layer 6 to

coat.Floor panel

1 and 2 seamed edge, slightly darker at their joint than the surface of floor panel 1 and 2.Therefore they provide protection against wear and destroy at the state that lays.

Floor panel

1 and 2 has the interlocking profile.They are designed to improved groove and tenon profile 14 or 15.Press Fig. 1 and 3, tenon 15a shape is engaged among the poor 14a sealedly, here, falls to cut a portion between tenon profile 15 and channel profile 14, and the

floor panel

1 and 2 that prevents interlocking is placed on the ground U that will lay when going up, and tenon profile 15 is extracted from channel profile 14.Certainly, can adopt traditional groove and tenon profile, they do not fall to cut portion and must glue together or take other measures yet.

Lay on panel floor often floating ground.In other words, they are gapped with respect to the wall in institute laying room.In addition, in order to suppress foot-operated sound, often use bases soft, that be used as

floor panel

1 and 2 laying ground U.Sink in this soft basis for the link position in

floor panel

1 and 2 helps the floor, the interlocking profile 14 that shape is sealed and 15 constitutes a common hinge G at interlocking state, as Fig. 1 and following will illustrate shown in Figure 3.The flexible interlocking profile that prevents of comprehensive hinge in this jockey is damaged.

Fig. 3 and 4 expressions have the floor panel 1 or the 2 another kind of forms of implementation of interlocking profile 14 and 15.

Interlocking profile

14 and 15 geometry designs and function are consistent with above-mentioned form of implementation of pressing Fig. 1.Therefore, use identical Reference numeral for identical feature.

In Fig. 3, be the seamed edge of

floor panel

1 and 2 with unique difference by the form of implementation of Fig. 1.In Fig. 3, use

layer

5 or 6 seamed edge that surmounts support plate 3 and 4 corner cuts further to introduce in the seamed edge seam of butt joint.At the seamed edge place of floor panel 1, the coating of use layer 5 almost arrives the tenon 15a upside of tenon profile always.At the seamed edge place of floor panel 2, the free end of channel profile 14 top cell walls is almost completely with using layer 6 to cover.The whole seam of the groove of interlocking and

tenon profile

14 and 15 has a kind of labyrinth type trend.This seam has the part and the part that faces

floor panel

1 and 2 downsides that

face floor panel

1 and 2 upsides.Tenon 15a and groove 14a are in support plate central authorities substantially, between described these seam portion.Joint face is invaded by moisture and foul when daily use to a greater degree towards the part of

floor panel

1 and 2 upsides.In the remainder of seam, then invade less moisture and foul.Therefore, for the normal operating position of floor panel in home-

ranges

1 and 2, in the zone of that seam portion that faces

floor panel

1 and 2 upsides, coat just much of that.

Fig. 4 represents a kind of simple especially form of implementation of

floor panel

1 and 2, represents among the figure that they have been placed on the ground U that will lay.The support plate 3 of these floor panels and 4 seamed edges are corner cut not.Support plate 3 and 4 upper surface are

flat.Use layer

5 and 6 to be placed on the flat upper surface of support plate 3 long-pending 4.Use the end of

layer

5 and 6 to flush each other.Tenon profile 15 and channel profile 14 have down the portion of cutting, and they couple together adjacent panel.Tenon profile 15 and channel profile 14 constitute a public hinge G.Certainly, support plate 3 and 4 also can be selected the interlocking profile that adopts other shapes sealed, has perhaps that traditional nothing falls to cut portion and the profile that must connect with glue.
