Problems solved by technology

However, with the promotion of various touch screen technologies, due to the high-frequency use of these products, the display surface of the product is easy to get dirty, scratched, and corroded by some chemical solvents. Therefore, the waterproof, anti-fouling, and anti-chemical agents of these products are improved. , Improving wear resistance, etc. are very necessary. At present, in the protection of electronic product display screens, many people use the method of sticking film, but this method has general effects and is also very limited, especially for large-screen computer TVs and outdoor screens. ATM machines, architectural glass curtain walls, large-sized smartphones, automotive glass, etc., cannot be applied

Abstract

The invention discloses a high-molecular nanometer polyester mirror-surface wear-resistant paint. The paint is composed of two components, i.e., polyester and a curing agent in a weight ratio of 3-4: 1. According to the invention, carboxylated 8-hydroxyquinoline, triethanolamine oleate soap and a composite aminated monomer solution are subjected to mixing and a reaction during polymerization so as to obtain an amidated polymer filling material with a good crosslinking degree; and the amidated polymer filling material enables a hard filling material and silica micropowder to be effectively bonded, so synergetic enhancement effect is produced.

Description

technical field [0001] The invention belongs to the field of coatings, and in particular relates to a polymer nanometer polyester mirror surface wear-resistant coating and a preparation method thereof.
