▎ 摘　　要

NOVELTY - A graphene based tire tread comprises 85-95 parts mass raw rubber, 1-5 parts mass hexagonal boron nitride, 1-5 parts mass white carbon black, 20-30 parts mass rubber carbon black, 1-3 parts mass stearate, 2-6 parts mass ultra-fine aluminum silicate, 7-13 parts mass graphene oxide, 1-5 parts mass antioxidant, 1-3 parts mass accelerator, 0.1-0.3 part mass scorch retarder, 1-3 parts mass surfactant and 15-20 parts mass halogenated butyl rubber latex. USE - Graphene based tire tread (claimed). ADVANTAGE - The tire tread has improved wear-resisting property, enhanced heat abstracting property, high durable degree, long shelf life and reduced cost. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for production of tire tread, which involves (1) dispersing graphene oxide powder in deionized water, adding reducing agent, filtering and washing to obtain graphene precipitate, (2) adding graphene precipitate to organic solvent to obtain graphene dispersion liquid, adding halogenated butyl rubber latex to graphene dispersion, stirring, mixing evenly to obtain mixed solution, (3) curing mixed solution to remove solvent, solidifying, drying to obtain graphene rubber composite material, (4) mixing raw rubber, graphene rubber composite material, hexagonal boron nitride, ultra-fine aluminum silicate, anti-aging agent, scorch retarder and surfactant, mixing at 50-70 degrees C for 5-7 minutes, adding stearate salt, mixing half of rubber carbon black and half of silica, (5) adding accelerator, residual rubber carbon black and white carbon black, mixing at 75-85 degrees C for 6-8 minutes to obtain initial tread compound, (6) mixing to obtain tread compound, and (7) extruding tread compound to obtain semi-finished tread.
