摘　　要：研究了低相对分子质量反式 1,4 聚异戊二烯蜡 (LMTPIW )在橡胶配方中的应用。用LMTPIW替代芳烃油用于SBR或SBR/TPI配方中 ,可改善混炼胶的加工性能 ;硫化胶的拉伸强度略有下降 ,回弹性、屈挠性能、热老化性能及抗湿滑性能都有所提高。当LMTPIW用量为 2 0份时 ,胶料的综合性能最佳。The application of low molecular weight trans 1,4 polyisoprene wax (LMTPIW) to rubber compound was investigated.The results showed that the processibility of mix was improved by using LMTPIW instead of aromatic oil in SBR or SBR/TPI compound;the tensile strength of vulcanizate decreased somewhat,and the resilience,flexibility,heat aging property and wet traction improved;and the optimum comprehensive properties of compound were obtained when 20 phr of LMTPIW was used.
