抗湿滑、低滚动阻力环保型溶聚丁苯橡胶 SOL RC2557TH生产技术和性能研究

介绍中国石油独山子石化公司自主研发的抗湿滑、低滚动阻力环保溶聚丁苯橡胶(SSBR)SOL RC2557TH的生产工艺和调整过程,并将试制产品与国外同类产品(2550H和5025-2HM)进行性能对比。采用先进的环保芳烃油作为填充油,通过提高门尼粘度生产的SOL RC2557TH相对分子质量及其分布与2550H相近,生胶门尼粘度基本相同,生胶耐热氧化性能、混炼胶硫化速率以及硫化胶的物理性能、抗湿滑性能和滚动阻力性能均与2550H和5025-2HM相当。

Research on Production Technology and Performance of Environmentally Friendly SSBR SOL RC2557TH

This paper introduced the production process and adjustment process of the environmentfriendly solution polymerized styrene butadiene rubber(SSBR)SOL RC2557TH with good wet skid resistance and low rolling resistance,which was independently developed by CNPC Dushanzi Petrochemical Company,and the properties of the trial product were compared with the similar products from abroad(2550H and 5025-2HM).It was found that the relative molecular weight and its distribution of SOL RC2557TH were similar to those of 2550H.Compared with 2550H and 5025-2HM,the Mooney viscosity and the thermal oxidation resistance of SOL RC2557TH raw rubber was basically the same,the curing rate of SOL RC2557TH compound,and the physical properties,wet skid resistance and rolling resistance of the vulcanizate were equivalent.
