Abstract

The invention relates to a compressible roller (1) comprising: a cylindrical rigid roller core (2); an intermediate layer (3) of silicone foam, which covers the roller core (2); and an outer layer (4) which is formed by a silicone elastomer and which covers the intermediate layer (3).

Description

The compressible roller that is used for printing machine
Technical field
The present invention relates to new compressible roller, it can be used for printing or bat printing (tampographie) and comprise the flexible portion that is made of Silicone foam.
Background technology
The constituent polyorganosiloxane composition of term " Silicone foam " expression foamed material (mousse) form.Silicone foam is well known in the art and its preparation is described in many patents.
In most of printing technologies, print roller is used.In order to realize better printing repeatability, developed a large amount of flexible printing rollers.
For example, patent US-A-3467009 has described the production of flexible printing roller, described flexible printing roller comprises roller core, the intermediate layer of polyurethane foamed material, natural rubber or neoprene and at least one compressible skin by the fibrous material preparation that is soaked with elastomer substances.
Patent EP-A-577920 has described a kind of compressible roller, and it comprises roller core, the intermediate layer of being made by nitrile/polyvinyl chloride foam material and the skin that comprises polyurethane sealing fitting (joint).
But, also unsatisfactory the printing that the type of the foamed material that adopts in the roller of these prior aries improves constantly for durability and the requirement aspect printing quality in print roller is used.
For example, the problem that runs in the production of these rollers relates to the production defective relevant with the not controlled foaming in foamed material intermediate layer, produce the defective relevant with the bubble that has oversized dimensions and in expanded material the bubble distribution of sizes inhomogeneous, thereby affected the mechanical performance of described roller.
And the foamed material that uses in the prior art no longer meets the restriction that new industrial process is brought.For example, in the field such as the roller that produce to be used for bat printing, usually use centrifugation technique, this has brought new foaming restriction, this thereby affected size and the distribution of sizes of the bubble of expanded material, and this is key factor for printing with roller.In fact, when these bubbles oversize and when the distribution of the size of described bubble is large in expanded material, can cause the anisotropy of the physical property of described roller.
Thereby, to use as bat printing (or roller printing) for some, the particular characteristic of foamed material is looked for.Bat printing is a kind of indirect printing technique.The pattern that prints is carved on supporter in advance, then printing forme is attached on pad printer; Then with ink deposition on the part of engraving with by the liner made by Silicone foam or roller with this design transfer to the object that will print.In order to realize high-quality engraving and printing, be necessary that the liner of being made by Silicone foam or roller is made of undersized bubble and the distribution of sizes of these bubbles in this material wanted evenly so that printing ink can deposit equably and transfer on the receiving layer that is supported by the Silicone foam layer, allow simultaneously the accurate reproduction of described engraving.Term " undersized bubble " refers to that its width (or diameter) is less than or equal to the bubble of about 1mm, term " middle-sized bubble " refers to that its width (or diameter) is the bubble of 1-1.5mm, and for " large-sized bubble ", width (or diameter) is greater than 1.5mm.
Thereby for this application, the needs that obtain to have undersized bubble and steep uniformly the foamed material of distribution of sizes are sought especially.
Flexible printing is with the preparation of the foaming of roller part thereby be the theme of special concern in print field.
Description of the Prior Art the technology of multiple acquisition Silicone foam.The first technology adopts condensation reaction, discharges volatile byproducts.Be exactly particularly this situation for the system of the condensation reaction of using the SiH-SiOH type, this reaction discharges hydrogen, and it has played the effect of pore-foaming agent (agent porogene).For example, French Patent (FRP) FR-A-2 589 872 has described the precursor composition of the Silicone foam that comprises following component: comprise the organic silicon-containing polymer that has with the siloxane unit of the oh group of silicon bonding, comprise the organic silicon-containing polymer that has with the siloxane unit of the hydrogen atom of silicon bonding, catalyst such as tin compound, and the segmentation filler that comprises the silica that becomes hydrophobic through processing.These compositions solidify via polycondensation reaction, although and it is satisfactory in many aspects, but owing to using tin catalyst to be considered to not satisfied, tin catalyst can apply some undesirable toxic action at the composition of the tin catalysis described in French Patent (FRP) FR-A-2 589 872.
Optional form described in US Patent No.-B-3 923 705 be to provide comprise with the composition of the polydiorganosiloxanepolyurea of the hydrogen atom of silicon bonding, this hydrogen atom be used under the existence of platinum catalyst with the condensation reaction of the polydiorganosiloxanepolyurea of the hydroxyl (silanol) of silicon bonding.Therefore this reaction makes and can consist of network when the generation Silicone foam forms necessary hydrogen.In this class preparaton, formation and the cross-linked speed of gas are proportional, so the density refractory of gained foamed material to be controlling, thereby explanation is in the difficulty that is obtained by this technology aspect low density foam material.These compositions can comprise in addition with the polydiorganosiloxanepolyurea of the vinyl of silicon bonding, they by with simultaneously crosslinked with the polyaddition of the polydiorganosiloxanepolyurea of the hydrogen atom of silicon bonding, thereby participate in the structure of Silicone foam network.
According to the another kind of optional form described in US Patent No.-B-4 189 545, prepare Silicone foam by the composition that comprises following component: water, with with the polydiorganosiloxanepolyurea of the vinyl of silicon bonding, comprise with chain in and that not only have in the unit of the end of the chain with the hydrogen atom silicon bonding in order to can serve as the polydiorganosiloxanepolyurea of crosslinking agent.Water and the polysiloxanes reaction that comprises hydrogenation functional group, thus hydrogen and silanol produced.Silanol is then via condensation reaction and the polydiorganosiloxanepolyurea reaction that comprises hydrogenation functional group, thereby produce the second hydrogen molecule, and another will comprise the polydiorganosiloxanepolyurea reaction of hydrogenation functional group simultaneously with the polydiorganosiloxanepolyurea with the vinyl of silicon bonding via addition reaction and another, thus the structure of participation Silicone foam network.The main contributions that this technology is made is to add silanol but adds a small amount of water generates hydrogen.
In patent US-4 590 222, Silicone foam is prepared by the composition that comprises following material: polydiorganosiloxanepolyurea, resin, platinum based catalyst, Organhydridosiloxaneresins, on end unit with polysiloxane, filler and the Organic Alcohol of oh group.
Yet the technology of utilizing silanol to originate as pore-foaming agent is tended to produce to be had the too high foamed material of numerous application density, and for example those intentions are used for the application of transportation industry.In addition, when obtaining the foamed material of intermediate density, this normally realizes take mechanical performance (fracture strength, tearing strength etc.) as cost.
Another technology is to use pore-foaming agent or the pore additive that adds in organosilicon matrix, it expands material by following approach under heat effect:
-decomposing release gas, the particularly situation of azo derivative such as Celogen Az, it can make and can discharge nitrogen, carbon dioxide and ammonia.Although be widely used in other material, there is serious toxicity problem (discharging hydrazine) in this class pore-foaming agent,
The situation of-phase transformation (liquid is to gas), particularly low boiling point solvent.
Another example of the precursor composition of Silicone foam is described in list of references WO-A-00/46282.Described composition comprises by the crosslinked organosilicon basic substance of polyaddition and (comprises the polysiloxane oil of the polysiloxane oil of ≡ SiH functional group/comprise ≡ SiVi functional group/Pt catalyst, Vi=vinyl wherein), comprise the compound of hydroxy functional group and wollastonite (described example has been described the composition with high filler content, is the filler of about 21 weight portions with respect to the gross weight of composition).Should be noted that the viscosity (embodiment 1, table 2) of the composition for preparing in an embodiment is all greater than 190 000mPas.As above-described, known (referring to US-B-4 418 157, the 2nd hurdle 13-24 is capable) This combination The viscosity of thing is larger, and the density of gained foamed material is lowerShould be noted that, composition (list of references WO-A-00/46282 from viscous, table 2, the 13rd page, composition [1-1], viscosity 274 is 000mPas) to minimum composition [1-3] (viscosity=198 of viscosity, 000mPas), the density of gained foamed material is increasing (from 0.20g/cm 3To 0.25g/cm 3), thereby confirmed about obtained the known teachings of low density foam material difficulty by the composition of low viscosity (viscosity is less than 30 000mPa.s) before crosslinked.In fact, due to end user or the producer that uses the Silicone foam production line in the reason of using these Composition Aspects to be optimized, importantly can have following such composition, said composition existed with the not too sticking form that easily flows in suitable utensil before crosslinked.
Thereby, in the preparation of print roller, importantly obtain low-density Silicone foam, to alleviate the weight of the equipment that uses in printing and transfer-print technology.
In this problem of considering thereby can be summarized in the technology of seeking between technical specification compromise, this is priori contradiction, seek to prepare low viscosity namely less than the Silicone foam precursor composition of 30 000mPa.s, and the precursor of Silicone foam, described Silicone foam has low-density, namely less than 0.25g/cm 3Density, have good mechanical performance, be less than or equal to the bubble size of 1mm and uniform bubble distribution of sizes in expanded material.In addition, the foamed material of looking for should no longer have the problem relevant with the intervention of new technology such as centrifugation technique in the commercial run of production print roller.
