▎ 摘　　要

NOVELTY - The fluorinated composite sealing material comprises a component (c1) includes 10-50 wt.% gamma -trifluoropropylmethylpolysiloxane polymer, 5-10 wt.% highly active magnesium oxide, 5-15 wt.% stearic acid, 5-20 wt.% butane cerium oxide, 5-10 wt.% high purity calcium oxide, 10-20 wt.% white carbon black, 5-10 wt.% vinyltri-tert-butylperoxysilane and 5-10 wt.% 2,4-dichlorophenol, and component (c2) including 10-40 wt.% copolymer, 5-10 wt.% graphene oxide, 5-8 wt.% fluororesin, 5-8 wt.% highly active zinc oxide, 5-8 wt.% calcium fluoride, 5-10 wt.% perfluoropolyether oil, 10-20 wt.% white carbon black, and 5-8 wt.% vulcanizing agent HTBBP. USE - Fluorinated composite sealing material. ADVANTAGE - The sealing material has excellent temperature resistance and elasticity, and changes the defects of a single silicone rubber or fluorosilicone rubber in terms of mechanical strength and compression creep. The low temperature resistance is 68-92 degrees C and the high temperature resistance is 250-350 degrees C, and the mechanical strength is greatly improved. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for preparation of the high-performance fluorinated composite sealing material, which involves (1) weighing the components in the component (c1) and put them into an experimental mixer, and mixing them at a temperature of 18-28 degrees C, (2) adding the copolymer into an experimental mixer, and controlling the temperature between 18-35 degrees C for mixing, adding graphene oxide, fluororesin, highly active zinc oxide, calcium fluoride, perfluoropolyether oil, and white carbon to the copolymer for 6-8 times when the copolymer is wound on the drum, fusing all the materials together, then adding the vulcanizing agent HTBBP, (3) adding the component (c1) after mixing in step (1) and the second component after adding the vulcanizing agent HTBBP in step (2) to the mixer together, mixing and kneading again, controlling the temperature of the drum at 18-35 degrees C, and fusing the component (c1) and the component (c2).
