A layer of hard coat containing fluorosiloxane graft polymer and ultraviolet curing resin is coated on the transparent PET film substrate, and alkali saponification treatment is performed on the hard coat. After performance test, the pencil hardness can reach 2H~8H. When high refractive index siloxane is used for the coating, it can be used as the base coating of the anti-reflection film. Add nitric acid to the composition of sodium acetate, tetraethoxysilane, methyltriethoxysilane, isopropanol and ethanol, and carry out a catalytic reaction for 2h to obtain silica sol, which can be used as a wear-resistant and scratch-resistant coating . Methacryloxypropyltrimethoxysilane, hydrolyzed polymer product is used as the main film-forming material, and TEOS hydrolyzed silica sol is introduced as an inorganic reinforcement to adjust the pH value of the two mixed solutions. The co-polycondensation reaction between the two hydroxyl groups is used to prepare an organic/inorganic composite transparent wear-resistant coating on the surface of the substrate. For the use of γ-glycidoxypropyltrimethoxysilane (KH-560, industrial grade), ethyl orthosilicate (TEOS, CP grade) and diethanolamine as the main raw materials to prepare silicone anti-fog and wear-resistant coatings , And conduct performance research. The results show that the obtained coating has excellent haze, abrasion resistance, transparency, adhesion and crack resistance. The surface is uniform and flat. It is a company specializing in the production of PET film with multiple functions, such as: transparent PET film, milky white PET film, release PET film, PET motor film, etc. With a wide variety of products, affordable prices, and environmental protection, we provide customers with excellent quality and service based on the service tenet of excellence in production, honesty and trustworthiness in distribution, and warm and thoughtful service.
