The graphene modified rubber composition is prepared from the following components in parts by weight: 80 to 95 parts of natural rubber, 5 to 20 parts of solution polymerized styrene-butadiene rubber, 35 to 70 parts of a reinforcing agent, 0.5 to 1.5 parts of graphene dispersion, 1 to 2 parts of a lubricating agent and 1.5 to 2.5 parts of a vulcanizing agent, wherein the graphene dispersion comprises graphene and a dispersing agent, and the weight ratio of the graphene to the dispersing agent is (2-4): 1. Through the raw material selection, formula and processing technology of the rubber material, the problems of dispersity and the like among the materials are solved, and through graphene modification, the strength of the material is improved by about 7%, the conductivity is improved by 100 times, and the abrasion characteristic of the material is improved by about 1 time. The obtained composite material has the advantages of good heat dissipation, good static conductivity, high strength, good wear resistance, low oil consumption, low carbon emission and the like, and can be widely applied to upper treads, lower treads and the like of aircraft tires.
