| 中文摘要: |
| 研究了高反式-1，4-聚异戊二烯(TPI)/ 高乙烯基聚丁二烯橡胶(HVBR)共混物的性能，特别是其滚动阻力、生热和抗湿滑性的平衡问题。试验结果表明，通过并用HVBR，可以大大改善TPI的抗湿滑性。与TPI比较，TPI/HVBR并用比为60/40时，0 ℃时的tanδ值增大了近3倍，并用比为40/60时，0 ℃时的tanδ值增大了7倍。TPI/HVBR在60和80 ℃时的tanδ值低于TPI，较好地解决了TPI使用过程中滚动阻力、生热和抗湿滑性的平衡问题。并用比适当的TPI/HVBR共混物具有较好的综合性能。适当配合的TPI/HVBR共混物在物理性能上还具有一定的互补作用。 |
| 英文摘要: |
| The properties of trans-1，4-polyisoprene (TPI)/high vinyl poly butadiene (HVBR) blends，especially the balance among rolling resistance，heat build-up and wet traction were investigated.The results showed that the wet traction of TPI improved greatly by blending with HVBR；tanδδ at 0 ℃ of TPI/HVBR with blending ratio of 60/40 increased nearly by three times when compared to that of TPI alone；and tanδat 0 ℃ increased by seven times when TPI/HVBR with blending ratio of 40/ 60 was used.The tanδ values at 60 and 80 ℃ of TPI/HVBR were lower than those of TPI respectively，thus the balance among rolling resistance，heat build-up and wet traction were obtained. |
