Problems solved by technology

[0002] There are many kinds of light-curing coatings, most of which are used for exterior decoration of light industrial products, such as televisions, refrigerators, washing machines, electric vehicles and other products, but for interior decoration of automobile lamps, they cannot meet special requirements, such as coating combination Adhesion, there are paint peeling and moiré spots in hot light, causing the light source to be unable to focus, and the paint film itself turns yellow after long-term use, which brings serious problems such as insufficient brightness of car lights

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 [0001] The invention relates to a light-curing coating mainly composed of acrylic resin, polyester resin and phenolic epoxy resin, which is especially suitable for vacuum spraying in various automobile lamps. Background technique [0002] There are many kinds of light-curing coatings, most of which are used for exterior decoration of light industrial products, such as televisions, refrigerators, washing machines, electric vehicles and other products, but for interior decoration of automobile lamps, they cannot meet special requirements, such as coating combination Adhesion, there are paint peeling and moiré spots in hot light, causing the light source to be unable to focus, and the paint film itself turns yellow after long-term use, which brings serious problems such as insufficient brightness of the car lights. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a paint for car lamp vacuum finishing ...
