摘　　要：对反式-1,4-聚异戊二烯(TPI)/天然橡胶(NR)并用胶体系配方进行优化。结果表明,在TPI/NR(15/85)并用胶体系中,加入2份芳烃油,0.5份硫化剂DTDM,1.5份抗返原剂WK901,混炼胶硬度适中,利于后续半成品的加工;TPI/NR并用胶的硫化特性基本不变,在保持基本配方物理机械性能的基础上,具有低生热性,优异的耐磨性能和耐屈挠性能,较低的滚动阻力,是一种较为理想的全钢子午线轮胎胎面配合。The recipe of TPI/NR（15/85）blend was optimized. The experimental data showed that the TPI/NR（15/85） blend had moderate hardness, convenient for manufacture technology of semi- product with 2 phr aromatic oil,0. 5 phr curing agent DTDM, 1.5 phr anti-recovery agent WK901. On the basis of keeping physical mechanical properties, the TPI/NR（15/85） vulcanizate had excellent low compression heat build-up and good abrasion resistance. Otherwise, the TPI/NR（15/85） blend remained curing characteristics. The flexibility and rolling resistance of optimized recipe improved. It was an ideal material for the tread compounding of all-steel radial tyre.
