溶聚丁苯橡胶2506的性能及其在轮胎胎面胶中的应用
对溶聚丁苯橡胶（SSBR）2506的结构及性能进行了测试,与乳聚丁苯橡胶（ESBR）1500进行了对比,并研究了SSBR 2506与天然橡胶（NR）并用在轮胎胎面胶中的应用。结果表明,与ESBR 1500相比,SSBR 2506具有较高的1,2-结构含量;SSBR 2506的焦烧时间和正硫化时间较长,加工安全性好,拉伸性能稍差,耐老化性能和耐磨性能大幅提高;SSBR 2506的玻璃化转变温度较低,抗湿滑性能稍差,滚动阻力大幅降低。当SSBR 2506/NR的质量比为20/80时,轮胎胎面胶的综合性能较佳。...

The results showed that, compared with ESBR 1500, SSBR 2506 possessed higher 1,2- structure content, longer scorch time and slower cu- ring rate, which improved the processing safety. Al- so the aging resistance and wear resistance of SSBR2506 increased significantly, while the tensile pro- perty was slightly inferior to ESBR 1500. SSBR 2506 had lower glass transition temperature, lower we |
