Antifouling scrubbing-resistant silane modified polyether sealant and preparation method thereof

The invention belongs to the technical field of sealants, and discloses an antifouling scrubbing-resistant silane modified polyether sealant, which is prepared from the following raw materials in percentage by weight: 35 to 50 percent of silane modified polyether resin, 0.5 to 3 percent of organic fluorosilicon resin, 32 to 60 percent of reinforcing filler, 0.5 to 2 percent of thixotropic agent, 1 to 5 percent of stabilizer, 0.5 to 4 percent of water removal agent and 0.5 to 4 percent of coupling agent. Wherein the silane modified polyether resin is silane modified polyether resin with the end sealed by alpha-silane; the organic fluorine silicon resin is prepared by carrying out hydrolytic condensation reaction on 3-glycidyl ether oxypropyl trimethoxy silane and tridecafluorooctyltriethoxysilane. The invention further discloses a preparation method of the organic fluorine silicon resin. The anti-fouling and scrubbing-resistant silane modified polyether sealant disclosed by the invention has very good anti-fou
