Abstract
The invention relates to paint for vacuum coating of car lights. The paint comprises the following ingredients in percentage by weight: 40-50% of polyester acrylic resin, 10-15% of a TM acrylic monomer, 18-25% of a TP acrylic monomer, 5-10% of phenolic aldehyde epoxy resin, 6-11% of a photoinitiator, 0.5-1.5% of one or additives, 5-10% of ethyl ester and the balance of a solvent, wherein the solvent is a mixture of butyl propionate and ethyl ester; the ratio of butyl propionate to ethyl ester is 1:2.4; the photoinitiator is an ultraviolet light absorbent; the additives comprise one or more of a drying agent, a toughening agent, an antifoaming agent, a leveling agent, a photostabilizer, an accelerating agent, a dispersing agent and the like. Compared with like vacuum paint, the paint provided by the invention has the advantages that the cost is reduced by about 40%, convenience is brought for construction, and the one-time qualification rate is high.
Description
Technical field
The present invention relates to a kind of based on the photo-cured coating of acrylic resin, vibrin, novolac epoxy, be particularly suitable for vacuum spraying in various automobile lamp.
Background technology
Photo-cured coating is various in style, major part is used for light industry product external decoration and covers with paint, lacquer, colour wash, etc., as products such as televisor, refrigerator, washing machine, power trucks, but be do not reach particular requirement for automobile lamp interior trim, as the sticking power that coating combines, in thermo-optical, there are depainting and moire spot, cause light source not focus on, after life-time service, coating paint film itself is anti-yellow, brings some problems such as wretched insufficiency to the luminance brightness of car light.
Summary of the invention
Technical problem to be solved by this invention is to provide the coating of the car light vacuum covering with paint that a kind of sticking power is good, thermotolerance is high.
For solving the problems of the technologies described above, the invention provides a kind of car light vacuum cover with paint, lacquer, colour wash, etc. coating, its component and weight percent as follows: polyester acrylate resin 40-50%, TM Acrylic Acid Monomer 10-15%, TP Acrylic Acid Monomer 18-25%, novolac epoxy 5-10%, light trigger 6-11%, auxiliary agent 0.5-1.5%, solvent 5-10%.
Described solvent mixes by proportioning 1:2.4 with the third butyl ester, ethyl ester.
Described light trigger is ultraviolet absorbers.
Described auxiliary agent comprises one or more of siccative, toughner, defoamer, flow agent, photostabilizer, promotor, dispersion agent etc.
The preparation method of the coating that above-mentioned car light vacuum is covered with paint, lacquer, colour wash, etc. comprises the steps:
(1) get the third butyl ester, ethyl ester generates solvent a by proportioning 1:2.4 mix and blend;
(2) first polyester acrylate resin is mixed with solvent a, form resin mixture liquor b;
(3) again resin mixture liquor b is added M Acrylic Acid Monomer, TP Acrylic Acid Monomer, novolac epoxy successively under low rate mixing; Then successively by light trigger, auxiliary agent spraying addition method, feed intake while stirring, feed intake and after terminating, within moderate-speed mixer 3-5 minute, namely make the coating of this car light vacuum covering with paint again.
Technique effect of the present invention: the coating that (1) car light of the present invention vacuum is covered with paint, lacquer, colour wash, etc. has carried out effective adjustment to coating internal chemical structure, molecular structure, the molecule content of coating is between 15000-35000, the depainting that modified resin coating of changing over exists, dark moire, anti-yellow phenomenon, coating is improved in secondary coating postadhesion power, molecular density improves has repaired dark moire phenomenon, and due to the thermotolerance of novolac epoxy, make coating paint film not anti-yellow under long-term trial state, thus improve the sharpness of paint film; (2) this coating cost compared with similar effect lacquer reduces about 40%, easy construction and disposable qualification rate is high.
