Problems solved by technology

[0003] At present, young people consume a lot of mobile phone casings and electronic product protection plastic casings. Most users pursue the aesthetics and wear-resistant performance of mobile phone casings. However, mobile phone casings are made of plastic (ABS), and coatings are needed to achieve corresponding protection. In order to attract more users, although water-based coatings are more and more widely used due to their environmental protection performance, due to the surface of plastic products, there are many problems when using water-based coatings to treat the shell of plastic products. Poor strength, after a period of use, the paint film will fall off, and there are still few water-based plastic paints with good performance, so the development of high-performance water-based plastic paints has very good practical significance and market demand

Abstract

The invention discloses a water-based metallic flexible coating for plastics. The coating comprises an aqueous elastic fluorocarbon emulsion, an aqueous hydroxy acrylic emulsion, polymethylsilsesquioxane, nano-zirconia, nano-alumina, pearl powder, a flame retardant, nanometer zinc oxide, an adhesion promoter, a pH adjuster, an antifoaming agent, a film forming additive, a dispersant, a substrate wetting agent, a thickener, a curing agent, a cosolvent, temperature-sensitive color changing powder and deionization water. The water-based metallic flexible coating for plastics realizes processing spraying of the outer shell of a plastic product to achieve the purposes of beautifying the appearance of the plastics and attracting consumers, and makes the sprayed plastics be health and safe and have the advantages of no harmful substance volatilization and good fireproof, antibacterial and wear-resistant properties.

Description

technical field [0001] The invention relates to the technical field of coating preparation, in particular to a water-based plastic metal flexible coating and a preparation method thereof. Background technique [0002] With the improvement of living standards, plastic products are more and more widely used. At present, people not only pursue good performance, but also pursue fashionable appearance. The use of coatings to treat the shell of plastic products is currently the most cost-effective way. At present, oil-based coatings still occupy most of the market due to their excellent performance, but oil-based coatings have a large content of VOC (volatile organic compounds), of which VOC is a volatile organic compound. Organic compounds, these volatile organic compounds include formaldehyde, ammonia, ethylene glycol, esters and other substances. When VOC reaches a certain concentration, it will cause symptoms such as headache, nausea, vomiting, fatigue, and even convulsions, ...
