The invention relates to the field of rubber materials, and relates to graphene-containing wear-resisting fluororubber and a preparation method of the graphene-containing wear-resisting fluororubber, in particular to a composite material which is prepared from graphene, nano-diamond powder and fluororubber together. The graphene-containing wear-resisting fluororubber comprises the components of the fluororubber, the graphene, the nano-diamond powder and fillings and is prepared by adopting a machine blending method. According to the graphene-containing wear-resisting fluororubber disclosed by the invention, the mechanical property and the wear resistance of existing fluororubber are greatly increased, the surface friction coefficient of a material is reduced, and meanwhile, better gas barrier property and better heat conducting property are obtained.
