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 an interior decoration coating for an automobile lamp. The coating comprises the following components by weight: 25 to 35% of novolac epoxy resin, 20 to 30% of acrylic resin, 5 to 10% of polyester resin, 3 to 5% of TM resin, 2 to 7% of TP resin, 2 to 3% of an initiator, 3 to 4% of an auxiliary agent and 30 to 40% of a solvent, wherein the solvent is prepared from mixing propyl butyl ester and ethyl ester with a weight proportion of 10 to 20% of propyl butyl ester and 80 to 90% of ethyl ester; the initiator is one or two selected from the group consisting of benzophenone and alpha-hydroxy ketone; and the auxiliary agent is one or more selected from the group consisting of a drying promoter, a toughening agent, a defoaming agent, a leveling agent, a light stabilizer, etc.. The interior decoration coating for the automobile lamp is effectively regulated in an internal chemical structure and a molecular structure of the coating; and the molecular content of the coating is in a range of 15000 to 30000, so depainting, dark-moire and yellowing phenomenons of a modified resin coating in the prior art are changed.
