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 hard anti-wear polyester mirror coating. The hard anti-wear polyester mirror coating comprises a polyester component and a curing agent component according to a weight ratio of (3-4):1. A carboxylated hard dispersion is mixed with and reacts with a composite aminated monomer solution in the polymerization process to obtain a well crosslinked amidated polymer filler, so the hard filler and silicon micro-powder are effectively combined, and the synergistic enhancement effect is reached.

Description

technical field [0001] The invention belongs to the field of coatings, and in particular relates to a hard anti-wear polyester mirror coating and a preparation method thereof. Background technique [0002] With the development of the electronics industry, especially the promotion and application of smart phones, large-screen TVs, and smart tablet computers, these products have now entered thousands of households and companies around the world. 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...
