The invention discloses a graphene rubber composition for a tire tread and a preparation method of the graphene rubber composition. The graphene rubber composition for the tire tread is prepared from the following raw materials in parts by weight: 100 parts of a diene elastomer, 40-100 parts of modified graphene masterbatch, 60-120 parts of reinforcing filler, 2-6 parts of resin, 4-7 parts of zinc oxide, 2-4 parts of stearic acid, 1.5-3.5 parts of sulfur powder and 1-2 parts of an accelerant. The added modified graphene masterbatch can be uniformly dispersed in rubber and has a good interface interaction with the rubber, the advantages of large specific surface area, high modulus, good thermal conductivity, good electrical conductivity and the like of a graphene material can be fully played, and the mechanical property, the wear resistance and the dynamic property of the graphene rubber composition are obviously improved; the compound is suitable for being used as tread rubber of aircraft tires, heavy-duty tires, high-performance automobile tires and the like.
