Abstract

The invention relates to the technical field of material surface treatment, and in particular relates to a high gloss coating process of the surface of a plastic substrate. The process comprises the following steps of: A. cleaning, B. surface pretreatment, C. coating blending, D. surface spraying, E. standing and F. roasting. The process has the following beneficial effects that: by controlling the processing technic conditions, the problems easily occurring on the surface of the product such as oil deposition, pitted surface, particles, picture frame effect and the like are effectively reduced; therefore the product surface has good levelling property, the formed coat is dense and uniform, the surface is bright and the polishing yield and first yield of the finished product of the plastic substrate are high; and besides, the adhesive property of the coating on the surface of the plastic substrate is improved by spraying the diluted coating on the surface of the plastic substrate, thus ensuring the uniformity of the coat and improving the product percent of pass.

Description

technical field

[0001] The invention relates to the technical field of material surface treatment, in particular to a surface high-gloss coating process for plastic substrates. Background technique

[0002] Some auto parts made of plastics such as polycarbonate (PC) and rubber materials such as ethylene propylene diene monomer (EPDM), such as airbag covers, center consoles, etc., need to be sprayed on the surface after the substrate is formed to Improve the surface quality of the product and obtain the desired surface decoration effect. At present, in order to achieve the high-gloss effect on the surface of the plastic product shell, two processes are mainly used: the traditional ultraviolet radiation (UV) spraying process and the fast-cooling, fast-heating high-gloss seamless injection molding process.

[0003] The high-gloss non-marking injection molding process with rapid cooling and rapid heating can make the surface of the product smooth, the surface gloss is good, and...
