Description
Technical field
The present invention relates to a kind of ultraviolet cured paint composition and mobile phone key.
Background technology
Ultraviolet-curing paint is a kind of environment-friendly and energy-efficient coating of the sixties in 20th century exploitation, gets final product fast setting under UV-irradiation, and not only curing speed is fast, and compares with heat curing coating and also to save the energy, has remarkable advantages.At present, it is not only widely applied on timber, metal, plastics, paper, leather, but also on materials such as optical fiber, printed-wiring board (PWB), electronic devices and components encapsulation successful Application.
For example, the coating of existing cell phone keyboard generally comprises colored paint layer (patterned layer) and surface transparent lacquer (protective layer).Cell phone keyboard is a ground with polycarbonate plastic mostly, during spraying generally with thermoplastic acrylic resin as the colored paint layer, the polyurethane acrylate paint that sprays one deck ultraviolet light polymerization again is as supercoat.The colored paint layer is meant that all have the coating of color; such as; priming paint is white; intermediate layer paint is a black; radium is carved the intermediate layer paint of removing part black, exposes the white primer of numerical switch, and the numerical portion of this mobile phone key is a white; all the other places are black, spray the polyurethane acrylate paint of one deck ultraviolet light polymerization again as supercoat at last.Wherein, priming paint and intermediate layer paint all are colored paints.In this system and since colored paint need spray two-layer or two-layer more than, thickness is usually at 15～20um, the blocked up protective membrane hardness that causes of rete descends.Simultaneously because cell phone keyboard and staff contact friction are frequent; and the ultraviolet cured paint composition of existing supercoat mostly adopts urethane acrylate as matrix resin; add activity diluting monomer again and adjust system viscosity and cross-linking density; add light trigger, flow agent, dust-proofing agent, mute light powder etc. then and adjust surface effect, add organic solvent at last and combine.When this coating is used on the cell phone keyboard, hardness and wear-resistingly do not reach requirement.
Along with popularizing of electronic product, people also have further raising to its outward appearance, performance etc., for example prior art has research to adopt the ultraviolet curing chromatic coating composition to make the color effect of dazzling that supercoat improves button etc., for example adopts epoxy acrylate class prepolymer 5～30; Urethane acrylate class prepolymer 5～30; Polyester acrylic ester oligomer 5～10; Acrylic monomer 15～70; Light trigger 1～10; Pigment 1～35; Auxiliary agent 0.2～10; Dispersion agent 0.1～2 composition, can deep layer solidify, have decorative effect and hardness of paint film preferably, but because pigment easily hinders the active group contact of molecule, therefore wear-resisting, the scratch resistance of the coating of the colored ultraviolet cured paint composition preparation of this kind, performance such as adhere to and all have and reduce significantly, can not satisfy service requirements; And the dispersion of pigment in UV-cured resin and stable very difficult is prone to pigment and resin isolation in the storage process, bring difficulty to subsequent technique.This kind ultraviolet-curing paint is all relatively poor to the sticking power of base material simultaneously, and is general only as supercoat, not direct contact substrate surface.
Summary of the invention
The present invention is poor to the adhesive ability of base material for the ultraviolet cured paint composition that contains pigment that solves prior art, storge quality is poor, and performance such as wear-resisting, scratch resistance of Zhi Bei coating is undesirable simultaneously, can not satisfy the problem of the requirement of prior art.
Provide a kind of and can prepare that superelevation is wear-resisting, high rigidity, strong scratch resistant coating, and strong adhesion is the ultraviolet cured paint composition with polychromy effect of contact substrate surface, storge quality excellence directly, contain matrix resin, thinner, pigment and light trigger, contain or do not contain auxiliary agent, wherein matrix resin comprises aromatic acid vinylformic acid half ester and aliphatic urethane acrylate.
Aromatic acid vinylformic acid half ester of the present invention not only has higher curing speed, the glossiness height, and viscosity is low, and plastic basis material and metal base are all had good adhesive, and chemical resistance is good.Particularly the present inventor is unexpected finds that it is to dispersing of pigments ability excellence, improved the storge quality of composition, particularly can overcome the problem that pigment reduces wetting, the adhesion property of matrix resin on the button base material, improve the flowability of matrix resin, and can not occur during coating curing shrinking uneven phenomenon, prevent the appearance of orange peel phenomenon.
Coating composition wettability of the present invention is strong; good fluidity; to different substrate materials such as plastics; metal all has excellent adaptability; strong adhesion; can directly be coated on substrate surface; as decorating or carve out required patterned layer; should not come off; the coating of coating composition preparation simultaneously of the present invention has high rigidity; good abrasion resistance and anti-zoned trace ability; pencil hardness on PC or PMMA button can reach 3～6H (ASTM D3363; load: 1000g; pencil: Mitsubishi (uni)); anti-scratch performance can reach 4～6N (gauge head Φ: 0.75mm; test angle: 90 °; applying certain load streaks with the speed of 1cm/s); protective layer can additionally be set; further stoped because the coming off of the number of plies of coating and problems such as coating consistency that thickness brings; the appearance of problem such as orange peel and uneven thickness has further improved the quality of product.This kind technology has also been saved cost, has been improved product yield etc. simultaneously.And the coating of coating compound preparation of the present invention is bright in luster, and good decoration effect is arranged, and can satisfy the requirement of prior art, can directly carve out required patterned layer thereon.
Another object of the present invention provides a kind of mobile phone key, the surface of mobile phone key is followed successively by base material and coating from the end to the face, coating comprises patterned layer, wherein patterned layer be above-mentioned ultraviolet cured paint composition be coated on substrate surface after solidify, engraving makes.
Coating composition of the present invention can directly be coated on the surface of button; be cured engraving; as patterned layer; bright in luster; have good decoration effect, can satisfy the requirement of prior art, simultaneously wear-resisting, the high rigidity of superelevation, strong scratch resistance; can satisfy the frequently requirements of contact friction parts for a long time such as button directly as supercoat again.Excellent performances such as appearance of mobile phone keys of the present invention is attractive in appearance, wear-resisting.
