Screen protection silicone material is a coating with active silane groups, groups and fluorine-modified organic groups. After coating on the screen, it forms a transparent film layer with a thickness of 10nm to 20nm. With low friction coefficient and hydrophobic and weathering properties of siloxane, the water contact angle of the film layer is greater than 115 °, and the contact angle of oleic acid is greater than 74 °, which makes the screen protection film layer excellent Water and oil repellency, reduce fingerprints and various stains, and improve the ability to wipe clean. Doping nano-silica in the silicone protective coating can also improve the hardness and abrasion resistance and abrasion resistance of the material after film formation. At present, the commercially available products can be rubbed back and forth 3,000 times (provided that the load is 1kg, 0000 # After steel wool, contact area 20mm × 20mm), the surface water contact angle is still greater than 108 °. In addition, nano-titanium dioxide is added in a physical blending method, and titanium is used in silicone coatings. Among them, nano-titanium dioxide photocatalyst generates extremely strong free radicals, which can be used to make anti-pollution and sterilization protective coatings for cover materials.
