Temperature-resistant oil-resistant deacetonized organic silicon sealant as well as preparation method and application thereof

The invention provides a temperature-resistant and oil-resistant deacetonized organosilicon sealant as well as a preparation method and application thereof, and relates to the technical field of organosilicon sealants. The deacetone type organic silicon sealant is prepared from the following raw materials in parts by weight: 50 to 70 parts of alpha, omega-dihydroxy polydimethylsiloxane, 30 to 50 parts of alpha, omega-dihydroxy polymethyl (3, 3, 3-trifluoropropyl) siloxane, 3 to 10 parts of silicon resin, 100 to 200 parts of filler, 5 to 15 parts of cross-linking agent, 2 to 10 parts of coupling agent, 0.5 to 5 parts of catalyst, 3 to 10 parts of heat-resistant agent, 0.5 to 5 parts of structured control agent and 0.5 to 5 parts of storage stabilizer. The catalyst is a silanized full carboxylic acid derivative. The deacetonized organosilicon sealant has excellent high temperature resistance and oil resistance, and is suitable for being used as a gasket formed in situ. 本发明提供一种耐温耐油脱丙酮型有机硅密封胶及其制备方法和应用，涉及有机硅密封胶技术领
