Synthesis of high refractive index silane used for organosilicon wear resistant paint

The invention discloses synthesis of a high refractive index silane used for organosilicon wear resistant paint. The high refractive index silane comprises a main material and an auxiliary material; the main material is composed of 10 to 20 parts of aluminium isopropoxide, 11 to 19 parts of alkenyl silane, 8 to 16 parts of ethyl orthosilicate, 12 to 18 parts of butyl titanate, 5 to 11 parts of diphenyl sulfide, 4 to 10 parts of trimellitic anhydride, 3 to 7 parts of dimethyl formamide, 6 to 12 parts of vinylsilane, 5 to 11 parts of butane dithiol, 3 to 9 parts of octane dithiol, and 2 to 4 parts of 2-methylbenzenethiol. The high refractive index silane is capable of improving mixture dissolving transparency in preparation of organosilicon wear resistant paint silane, providing foundation for later moulding, avoiding situations such as high turbidity after mixing with dissolved compounds and influences on subsequent preparation process; an organic coating layer is formed; the viscosityis high; better effects a
