Fluororubber composite material with excellent performance and preparation method thereof

The invention relates to the technical field of fluororubber materials, and particularly discloses a fluororubber composite material with excellent performance and a preparation method thereof, and the fluororubber composite material is prepared by mixing the following raw materials: binary fluororubber, a vulcanizing agent, stearic acid, active light magnesium oxide, calcium hydroxide, bisphenol AF, BPP, N990 carbon black, tributyl phosphate, a novel flame retardant and functionalized aluminum hydroxide. Cerium oxide, antimony trioxide and silicon dioxide. The heat capacity improving effect of tributyl phosphate novel flame retardant functionalized aluminum hydroxide, the flame retardant effect of antimony trioxide and silicon dioxide and the effect of cerium oxide on improving the comprehensive mechanical property of rubber are utilized, so that the fluororubber blend composite material with the novel formula has the advantages that the hardness is not obviously changed; the fluororubber composite material
