▎ 摘  要

NOVELTY - A rubber composition comprises a diene-based rubber, graphene oxide, and carbon black. USE - Rubber composition used for tread portion and sidewall portion of tires for passenger car, light-truck and bus. ADVANTAGE - The rubber composition has excellent tensile strength. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for manufacture of rubber composition, which involves wet-mixing rubber latex and graphene oxide aqueous dispersion to prepare a wet masterbatch, and dry mixing and vulcanizing the wet masterbatch and carbon black.
