▎ 摘　　要

NOVELTY - A rubber composition comprises styrene butadiene rubber, silicon dioxide, bis3-(triethoxysilyl)propylpolysulfide, graphene, where the graphene has a thickness of less than about 3.2 nm, a particle size of between about 50 nm and about 10 μm, and contains greater than about 95% carbon, aliphatic hydrocarbon resin, treated distillate aromatic extract, N-(1,3-Dimethylbutyl)-N'-phenyl-1,4-phenylenediamine, 2,2,4-trimethyl-1.2-dihydroquinoline, paraffinic wax, microcrystalline wax, zinc oxide, stearic acid, N-cyclohexyl-2-benzothiazole sulfonamide, 1,3 diphenylguanidine, sulfur and pre vulcanization inhibitor. USE - Rubber composition used as an additive in silica tread applications. ADVANTAGE - The rubber composition shows increased barrier protection for tire innerliners, with no tradeoffs in other characteristics and can be in various forms and which can be portion of the present teaching, such as a powder, in pastilles or pellets using wax as a carrier, aiding dust suppression, in pre-weight sealed, low-melt temperature polyethylene bags, and melt or solution blended with a compatible polymer, such as butyl rubber or halobutyl rubber and then compounded as part of the total rubber hydrocarbon content.
