The invention discloses an anti-tear silicone rubber compound and a preparation method thereof, and belongs to the field of chemical industry. According to a silicone rubber base material for preparation, fluorine-containing siloxane is added in a mixed rubber base material, so that oil resistance of the silicone rubber is improved, and advantage combination of the silicone rubber and a mixed rubber additive are increased. Mixed rubber filler for preparation is prepared by taking white carbon black and nano carbon tubes as raw materials, so that temperature resistance of the rubber compound isimproved, and bonding performance between the rubber compound and a the silicone rubber matrix is improved. A cross-linking additive for preparation is prepared by taking lac and fumaric acid as rawmaterials, and has relatively good tear resistance and tensile strength. Aramid fiber short fibers and aramid fiber pulp are added, so that cross-linking activity in a mixing process is improved. According to the invention, the silicone rubber base material is added to improve oil resistance, and mixed fibers are added in the mixing process, so that various properties of the rubber compound are well combined. According to the invention, the problems of poor oil resistance and poor tear resistance of existing silicone rubber are solved.
