Abstract

The application provides a vibration wear-resistant coating and its preparation method and spraying process, including a PU-type primer and a UV light-curing topcoat. The PU-type primer components include 40-50 parts of thermoplastic acrylic resin, 10-20 parts 1 to 3 parts of cellulose acetate butyrate, 1 to 2 parts of adhesion promoter, 2 to 4 parts of additives, 15 to 25 parts of pigments and fillers, 20 to 30 parts of mixed solvents, UV photocurable topcoat components include 10-20 parts of high-functionality urethane acrylate, 15-25 parts of six-functionality urethane acrylate, 15-28 parts of four-functionality urethane acrylate, 4-10 parts of di-functionality urethane acrylate, 0.5-1 part of dispersant , 0.5-1 parts of leveling agent, 0-10 parts of matting powder, 0-25 parts of wax slurry, 0-10 parts of photoinitiator, 20-30 parts of mixed solvent, applied to the frame of mobile phone (plastic material) or the side key of mobile phone It can improve the vibration wear resistance and durability of the product, and prevent the paint film from falling off after long-term use.

Description

technical field [0001] The invention belongs to the technical field of coatings, and in particular relates to a vibration wear-resistant coating, a preparation method and a spraying process thereof. Background technique [0002] Due to the variety of primer colors for 3C electronic products, such as mobile phone electronics, these primers have a disadvantage, the paint film surface is not wear-resistant, and the chemical resistance is not good. Therefore, a layer of UV topcoat is usually sprayed on this primer to meet the requirements of wear resistance and chemical resistance. However, after a period of time, the ordinary UV coating used may cause the paint film to fall off, the gloss changes greatly, and the vibration Insufficient wear resistance and other disadvantages. It brings major quality problems to the appearance, durability and durability of the product. [0003] With the advent of the 5G era, metal shielding of signals is obvious, and demetallization has become...
