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 polyurethane macromolecule nano mirror surface thin film. The polyurethane macromolecule nano mirror surface thin film is composed of a component a and a curing agent component in a weight ratio of (3-4):1. The polyurethane macromolecule nano mirror surface thin film has the advantages that the added butylmercaptooxo stannane, stannous sulfide, ricinoleic acid and the like can effectively improve stability strength of the paint film finished product, by virtue of an esterification modified monomer, viscosity of the polymer finished product is improved, antistripping strength of the pain film with a base material is improved, and adhesion is enhanced.

Description

technical field [0001] The invention belongs to the field of coatings, and in particular relates to a polyurethane polymer nano-mirror film 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 l...
