摘要
研究国产充环保油丁苯橡胶(SBR)1739的性能,并与进口产品进行对比。结果表明:国产SBR1739生胶含油量相对稍高,Tg较低,加工性能较好;混炼胶加工安全性高,硫化速度稍慢,宜采用较高的挤出温度;硫化胶弹性较大,滚动阻力较小,抗湿滑性能优异。国产SBR1739合成时可以适当减小特大相对分子质量级分含量,以改善其挤出加工性能。
The properties of domestic environment-friendly oil extended SBR1739 were studied, and compared with imported products. The results showed that, domestic SBR1739 possessed a little higher oil content,lower glass transition temperature,and better processability. Its mix also possessed better processing safety,lower curing rate,and thus needed higher extrusion temperature. Its vulcanizate showed higher elasticity, lower rolling resistance, and excellent wet skid resistance. To improve the extrusion property,the content of higher molecular weight part of SBR1739 needed to be properly reduced.
