[summary of the invention]
In the display window protective panel of the portable data assistance of Ti Chuing, existed the not necessarily sufficient problem of the mar resistance of solidifying tunicle in the past.In addition,, hot and humidly perhaps pushed down, exist and solidify the problem that crackle takes place in the tunicle easily if be exposed to even it is abundant to solidify the mar resistance of tunicle.So the object of the present invention is to provide excellent scratch resistance is set, and is not easy to take place the display window protective panel of portable data assistance of the curing tunicle of crackle.
What the present inventor studied with keen determination found that, by using the curable coating of regulation, forms the curing tunicle of specific thickness on the resin substrate surface, just can achieve the above object, thereby finish the present invention.Just the invention provides the fender of portable data assistance display window; it is characterized in that on the resin substrate surface; by containing the curable coating of the compound that has at least 3 (methyl) acryloxies in the molecule, forming thickness is the curing tunicle of 2～6 μ m.
[effect of invention]
The fender of portable data assistance display window of the present invention, even owing to hot and humidly or pushed down to be exposed to, the state that also is not easy to take place crackle is provided with the high curing tunicle of mar resistance, so can effectively protect this display window.
[embodiment]
As the resin of the substrate that constitutes portable data assistance display window protective panel of the present invention, for example can enumerate methacrylic resin, polycarbonate resin, polystyrene resin, styrene-acrylonitrile copolymer, triacetyl cellulose resin etc.Wherein the transparency of methacrylic resin is high, and rigidity is also high, so be very suitable as the resin that constitutes substrate.
Methacrylic resin is the polymkeric substance based on methacrylate, for example both can be the homopolymer of methacrylate, also can be the above and following multipolymers of methacrylate other monomer 50 weight % in addition of methacrylate 50 weight %.As methacrylate, the preferred alkyl methacrylate that uses as methyl methacrylate and Jia Jibingxisuanyizhi especially preferably uses methyl methacrylate.In addition, as the monomer beyond the methacrylate, for example can enumerate aromatic series alkenyl compound, as the unsaturated carboxylic acid of acrylic acid and methacrylic acid, as the acrylate of methyl acrylate and ethyl acrylate, as the thiazolinyl cyanogen compound of vinyl cyanide and methacrylonitrile etc. as styrene and methyl styrene.
Can cooperate other composition in the resin of formation substrate, use as resin combination.As this gradation composition, for example can enumerate rubber particles, colorant, antioxidant, ultraviolet light absorber etc. as dyestuff and pigment.If the compound rubber particle, then the resistance to impact of resin substrate and flexibility are improved, and are not easy crackedly, are desirable.
As rubber particles, for example can use various rubber particles such as acrylic acid series, butadiene-based, styrene-butadiene system.Wherein, consider, preferably use the acrylic rubber particle from the weatherability viewpoint.As the acrylic rubber particle, for example can use contain with as the alkyl acrylate of butyl acrylate as the single layer structure particle of the elastomeric polymer of main body and contain with methyl methacrylate be provided with around as the internal layer of the rigid polymer of main body contain with as the alkyl acrylate of butyl acrylate as the outer field particle having multilayer structure of the elastomeric polymer of main body etc.In the above-mentioned elastomeric polymer, the general a spot of polyfunctional monomer of copolymerization.
In addition, can also use aptly to be provided with around the above-mentioned elastomeric polymer and contain with the particle of methyl methacrylate as the outermost sandwich construction of the rigid polymer of main body.For example can enumerate around containing based on internal layer as the elastomeric polymer of the alkyl acrylate of butyl acrylate, setting contains based on the outer field double-decker particle of the rigid polymer of methyl methacrylate with around the internal layer that contains based on the rigid polymer of methyl methacrylate, setting contains based on the middle layer as the elastomeric polymer of the alkyl acrylate of butyl acrylate, is provided with around again in this middle layer to contain based on the particle of the outer field three-decker of the rigid polymer of methyl methacrylate etc.Such sandwich construction rubber particles, for example open in the public clear 55-27576 communique of spy.The particle of preferred especially above-mentioned three-decker, the particle of recording and narrating among the embodiment 3 of special public clear 55-27576 communique are one of preferred compositions.
As rubber particles, consider that from the viewpoint of skin hardness, resistance to impact and the surface smoothing of resin substrate preferably using mean particle diameter is the particle of 0.1～0.4 μ m.If the mean particle diameter of rubber particles is too little, then the skin hardness of resin substrate is insufficient, or resin substrate becomes fragile.On the other hand, if the mean particle diameter of rubber particles is too big, then has the tendency of damaging the resin substrate surface smoothing.Rubber particles generally can by the addition of adjusting emulsifying agent and the addition of monomer etc., can be controlled mean particle diameter in needed value by the emulsion polymerization manufacturing in this manufacture process.
When the compound rubber particle is made resin substrate in resin, the ratio of the two, preferably making resin is 50～85 weight portions, making rubber particles is 15～50 weight portions.If the amount of rubber particles very little, then the resistance to impact of resin substrate and flexibility can not get abundant raising; If too much, then the skin hardness of resin substrate and rigidity are insufficient, so will not be preferred.
Resin substrate can be sandwich construction as required.Compound rubber particle in resin for example, improve resistance to impact and flexibility, but skin hardness and rigidity but are in the tendency of reduction, so form the layer that does not contain rubber particles by surface at the layer that contains rubber particles, when the former contains the resistance to impact and flexibility of rubber layer in performance, can improve the skin hardness and the rigidity of resin substrate.At this moment the thickness that contains rubber layer with respect to the resin substrate gross thickness preferably more than 50%, more preferably more than 60%.If this ratio is too little, then the resistance to impact of resin substrate and flexibility might be insufficient.Make the resin substrate of such sandwich construction, can use as having many extruding machines and the resin of extruding from many extruding machines being carried out laminated many material road mode or the isostructural known multi layer extrusion machine of feed head mode.
When the surface formation that contains rubber layer did not contain the layer of rubber, the layer that does not contain rubber needn't only get final product in one side formation on the two sides that contains rubber layer as mentioned above.If form the layer that does not contain rubber on the two sides, then be not easy to bring into play the resistance to impact and the flexibility that contain rubber layer.And form layer resin substrate that forms that does not contain rubber at a side surface that contains rubber layer; at least form on the surface of the layer that does not contain rubber and solidify tunicle; preferably make it towards face side (side that the user directly sees or contacts); fender as the portable data assistance display window uses; further improve the mar resistance of solidifying tunicle by this method; even meanwhile be subjected to strong pushing; not only solidify tunicle and be not easy to take place crackle; and because dorsal part contains the effect of the flexibility of rubber layer, resin substrate itself also is not easy to damage.
Resin substrate both can be as common plate (sheet material) and film, and the surface is the plane, also can be as convex lens and concavees lens, and the surface is a curved surface.The microtexture of micro concavo-convex etc. can also be set on the surface in addition.The thickness of resin substrate is preferably more than the 0.1mm, and below 3.0mm.
At least one side surface of resin substrate forms the curing tunicle of mar resistance.This solidifies tunicle, contains the compound that has at least 3 (methyl) acryloxies in the molecule by use and forms as the curable coating of curable compound, can become the curing tunicle of excellent scratch resistance.In addition, in this instructions, so-called (methyl) acryloxy is meant acryloxy or methacryloxy, and " (methyl) " when in addition, mentioning (methyl) acrylate, (methyl) acrylic acid etc. also is same meaning.
As the compound that has at least 3 (methyl) acryloxies in the molecule, for example can enumerate trimethylolpropane tris (methyl) acrylate, trimethylolethane trimethacrylate (methyl) acrylate, five glycerine three (methyl) acrylate, pentaerythrite three (methyl) acrylate, pentaerythrite four (methyl) acrylate, glycerine three (methyl) acrylate, dipentaerythritol three (methyl) acrylate, dipentaerythritol four (methyl) acrylate, dipentaerythritol five (methyl) acrylate, dipentaerythritol six (methyl) acrylate, three ((methyl) acrylyl oxy-ethyl) isocyanuric acid ester etc.

Conductive particle, preferably its particle diameter is 0.001～0.1 μ m.The particulate that particle diameter is too little is difficult to carry out commercial production; If use the excessive particulate of particle diameter, the transparency of then solidifying tunicle reduces, so will not be preferred.In addition, the consumption of conductive particle, per 100 weight portion curable compounds are preferably 1～100 weight portion.If this consumption very little, then can not get enough antistatic effects; If too many, the mar resistance of then solidifying tunicle reduces, or the film forming reduction, so will not be preferred.
In addition, in the curable coating,, can contain solvent in order to adjust viscosity and to solidify the thickness etc. of tunicle.As this solvent, for example can enumerate alcohols as methyl alcohol, ethanol, propyl alcohol, isopropyl alcohol, normal butyl alcohol, 2-butanols, isobutyl alcohol, the tert-butyl alcohol, alkoxy alcohols as cellosolvo, butoxy ethanol, 3-methoxypropanol, 1-methoxyl-2-propyl alcohol, 1-ethoxy-2-propyl alcohol, ethyl ketone alcohols as diacetone alcohol, ketone as acetone, MEK, methyl isobutyl ketone, aromatic hydrocarbon based as toluene, dimethylbenzene is as ester class of ethyl acetate, butyl acetate etc.The consumption of solvent solidifies the thickness of tunicle etc. suitably to be adjusted according to the material of substrate, shape, coating process, target, usually the curable compound and per 100 weight portions of total amount of the conductive particle of use as required, the consumption of solvent is about 20～10000 weight portions.
Can also contain adjuvants such as stabilizing agent, antioxidant, colorant, levelling agent in the curable coating.By containing levelling agent, can improve the flatness and the mar resistance of solidifying tunicle.
Preferably use silicone oil as levelling agent, as its example, can enumerate dimethyl silicon oil, phenyl methyl silicone oil, alkyl aralkyl modified silicon oil, fluorosilicon oil, polyether modified silicon oil, fatty acid ester modified silicon oil, methyl hydrogen silicone oil, the silicone oil that contains silanol group, the silicone oil that contains alkoxy, the silicone oil that contains phenolic group, methacrylic acid modified silicon oil, amino-modified silicone oil, carboxyl acid modified silicone oil, methyl alcohol modified silicon oil, epoxide modified silicone oil, sulfhydryl modified silicone oil, fluorine modified silicon oil, polyether modified silicon oil etc.These silicone oil both can have been distinguished use separately, also can use simultaneously more than 2 kinds.
The consumption of silicone oil, with respect to the curable compound and as required per 100 weight portions of total amount of employed conductive particle be generally 0.01～20 weight portion.If this consumption very little, then be difficult to see required effect; If so intensity reduction too many then that solidify tunicle is will not be preferred.
After the curable coating of above explanation is applied to substrate surface, carry out drying as required, then, can form the curing tunicle of excellent scratch resistance on the resin substrate surface by making the curable curing of coating of formation.
The coating of curable coating for example can be undertaken by methods such as nick version roller rubbing method, rolling method, dip coating, method of spin coating, mouthful pattern rubbing method, stream casting transfer printing, curtain coating, spraying processes.
The curing that curable is filmed is preferably undertaken by the irradiation active energy ray.As active energy ray, can enumerate electron ray, ultraviolet ray, visible light etc., suitably select according to the kind of curable compound.When using ultraviolet ray and visible light, use Photoepolymerizationinitiater initiater usually as active energy ray.
As Photoepolymerizationinitiater initiater, for example can enumerate acetophenone, the acetophenone benzyl ketals, anthraquinone, 1-(4-isopropyl phenyl-2-hydroxy-2-methyl third-1-ketone, carbazole, xanthone, 4-chloro benzophenone, 4,4 '-diaminobenzophenone, 1,1-dimethoxy deoxybezoin, desoxybenzoin, 3,3 '-dimethyl-4-methoxy benzophenone, thioxanthones, 2,2-dimethoxy-2-phenyl acetophenone, 1-(4-dodecylphenyl)-2-hydroxy-2-methyl third-1-ketone, 2-methyl isophthalic acid-[4-(methyl mercapto) phenyl]-2-morpholino third-1-ketone, triphenylamine, 2,4,6-trimethylbenzene formyl diphenyl phosphine oxide, the 1-hydroxycyclohexylphenylketone, 2-hydroxy-2-methyl-1-phenyl third-1-ketone, Fluorenone, fluorenes, benzaldehyde, the benzoin ethylether, the benzoin propyl ether, benzophenone, Michler's keton, the 3-methyl acetophenone, 3,3 ', 4,4 '-tetra-tert peroxide carbonyl benzophenone (BTTB), 2-(dimethylamino)-1-[4-(morpholinyl) phenyl]-the 2-phenyl methyl]-the 1-butanone, 4-benzoyl-4 '-methyldiphenyl base sulphur, benzil etc.
