Abstract

The invention discloses a calcium fluoride-containing rubber seal ring material and a preparation method thereof. The material is prepared from the following raw materials: polyurethane rubber, calcium fluoride, N,N'-1,3-phenylene bismaleimide, vulcanizing agent PDM, di(dioctylpyrophosphato) ethylene titanate, antioxidant DSTP, modified bauxite, azelate and fatty alcohol-polyoxyethylene ether. The rubber seal ring material prepared by adopting polyurethane rubber as a main material has excellent performances of low price, high hardness, good strength, high elasticity, high wear resistance, tearing resistance, aging resistance, ozone resistance and radiation resistance; the modified bauxite is added in the raw materials, so that the internal binding force of the rubber seal ring can be increased, the performances of the rubber seal ring, such as elasticity, aging resistance, ozone resistance, tearing resistance and the like, can be effectively improved.
