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 polyurethane mirror surface coating. The polyurethane mirror surface coating is composed of a component a and a curing agent component in a weight ratio of (3-4):1. Butylmercaptooxo stannane, stannous sulfide, ricinoleic acid and the like added in the polyurethane mirror surface coating can effectively improve stability and strength of the finished product film, and modification of a monomer through esterification improves the viscosity of the polymer finished product, improves anti-peel strength between the film and a base material, and enhances adhesion.

Description

technical field [0001] The invention belongs to the field of coatings, in particular to a polyurethane 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.
