Fluorosilicone rubber and preparation method thereof

The invention discloses fluorosilicone rubber and a preparation method thereof, and the fluorosilicone rubber is obtained by mixing prefabricated rubber, 2, 4, 6-trifluoroaniline, a vulcanizing agent, a suspension, an emulsion and a functional filler, wherein the prefabricated glue is obtained by mixing (3, 3, 3-trifluoropropyl) dichloromethylsilane, fluorine-containing alkyne, dipropylene glycol monomethyl ether, 1, 1, 3, 3, 3-pentafluoro-2-trifluoromethyl propyl methyl ether and perfluoro-n-propyl vinyl ether, and carrying out a pressurized reaction; the turbid liquid is obtained by mixing and homogenizing modified silicon boride, potassium perfluorobutanesulfonate, ethylene glycol and water; the emulsion is obtained by mixing and homogenizing zein, long-chain dicarboxylic acid, acetone and water. The fluorosilicone rubber has the characteristics of low temperature resistance, aging resistance, high strength and the like. 本发明公开了一种氟硅橡胶及其制备方法，采用预制胶、2,4,6-三氟苯胺、硫化剂、悬浊液、乳浊液、功能填料混炼后得到；其中预制胶由(3,3,3-三氟丙基)二氯甲基硅烷、含氟炔
