环保油对不同结构溶聚丁苯橡胶性能的影响

研究环保油对线形和星形溶聚丁苯橡胶（SSBR）性能的影响。结果表明：以环保油（TDAE）替代高芳烃油（DAE），线形SSBR物理性能的变化趋势与乳聚丁苯橡胶一致；填充TDAE的星形SSBR偶联效率更高，在拉伸强度和拉断伸长率方面有不同于线形SSBR的变化趋势，且压缩生热低，耐磨性能好，但抗湿滑性能与填充DAE的星形SSBR相比稍差。;The influence of environment-friendly oil on the properties of linear and star-shaped SSBR was investigated. The results showed that，by using environment-friendly oil （TDAE） instead of DAE，the physical properties of linear SSBR were similar to those of ESBR. Because of the higher coupling efficiency of the TDAE extended star-shaped SSBR，the change of its tensile strength and elongation at break was different from the TDAE extended linear SSBR.The compression heat build-up of the TDAE extended star-shaped SSBR was lower and the abrasion resistance was better.But the wet skid resistance of the TDAE extended star-shaped SSBR was slightly lower than that of the DAE extended star-shaped SSBR
