NOVELTY - Graphene-containing car tire tread rubber comprises 5-30% graphene composite material. The raw material of graphene composite material uses the waste of artificial diamond production. USE - Graphene-containing car tire tread rubber. ADVANTAGE - The tire tread improves radiating performance of tire, improves the safety of driving, saves raw material, does not create pollution and reduces graphite raw material cost by 50-80%. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for the preparation of graphene composite material comprising pre-treating, dispersing in solvent, adding in high-pressure container at 400 degrees C for 0.5-10 hours under 20-300 MPa, performing centrifugal separation or evaporation drying to obtain the product.
