Abstract

The invention relates to a high-shielding UV treatment agent and a treatment process thereof. The high-shielding UV treatment agent is prepared from special modified acrylic ester, urethane acrylate,polyester acrylate, modified silicon dioxide, TMP3EOTA, HDDA, Ciba184, TPO, BASF819, leveling agents, butyl cellosolve, methylbenzene, isopropanol, ethyl acetate, butyl acetate and organic silicon leveling agents. A product obtained by using the formula and being treated by the treatment process has the advantages of high shielding performance, high wear performance, easy re-coating, high surfacedrying speed, high curing speed, fast film forming and the like; the problems of bottom hinging, color seepage and poor combination power do not occur after the re-coating; the treated coating surfacehas high smoothness, high luster degree, good smoothness and high qualified product rate, and solves the problems of nonuniform roughness degree, poor shielding performance, poor re-coating effect, construction inconvenience, low qualification product rate and the like of the surface coating of a product treated by the existing conventional UV treatment agent.

Description

technical field [0001] The present invention relates to the field of coatings, in particular to a UV treatment agent suitable for covering mobile phone shells, automotive interior parts, and shells of some high-end cosmetics made of plastic substrates such as PC, ABS, and ABS+PC, and its UV treatment agent. Processing technology. Background technique [0002] With the increasing expansion of the mobile phone market, the application of mobile phone coatings is also increasing. However, the competition in all walks of life is becoming increasingly fierce. In addition to differences in functions, price has also become one of the main considerations. Therefore, PC, When plastic substrates such as ABS and ABS+PC are sprayed and processed, the yield rate becomes a key indicator that can reduce production costs. At present, the products molded by plastic substrates such as PC, ABS and ABS+PC have the disadvantages of uneven surface roughness, poor heat resistance and poor coating ...
