Preparation method of vinyl tris(2,2,2-trifluoro) ethoxyl silane compound

The invention discloses a synthesis method of a vinyl tris(2,2,2-trifluoro) ethoxyl silane compound. The synthesis method is used for synthesizing the vinyl tris(2,2,2-trifluoro) ethoxyl silane compound by using alcoholysis of chlorosilane. The synthesis method provided by the invention comprises the following steps of: taking vinyl trichloro silane and trifluoroethanol as raw materials, feeding inert gases such as argon and nitrogen, taking dichloromethane as a solvent, reacting at a given temperature and time, and synthesizing the vinyl tris(2,2,2-trifluoro) ethoxyl silane compound. The synthesis method provided by the invention can be used for industrial production; the prepared product is a novel material containing a monomer of a fluorosilicone compound, organically combines the advantages of organic silicon and organic fluorine compounds and has the excellent performances of weather resistance, ageing resistance, solvent and oil resistance and the like while having the heat resistance and cold resistanc
