| 摘 要： | 研究了反式-1，4-聚异戊二烯（TPI）不N用量对TPI／天然橡胶（NR）并用胶物理机械性能和动态性能的影响，并对TPI／NR并用胶进行配方优化。结果表明，TPI与NR并用比为15／85时，混炼胶胶片光滑，硫化胶在保持基本配方物理机械性能的基础上，压缩生热性能明显提高，伸张疲劳系数有所提高；经优化配方后，TPI／NR混炼胶的粘合强度提高，硬度适中，利于后续半成品的加工，且硫化胶具有低生热性，滚动阻力降低，是一种较为理想的全钢子午线轮胎胎肩垫胶配合。

| Abstract: | The effects of the different TPI contents on physical mechanical properties, dynamic properties of TPI/NR vucanizates were investigated, and the basis recipe was optimized. The experi- mental data showed that the surface of TPI/NR（15/85） blend was smooth. On the basis of keeping physical mechanical properties,TPI/NR（15/85） blend had lower compression heat build-up and better coefficient of fatigue. TPI/NR blend had better adhesive strength,moderate hardness with majorized recipe,and convenient for manufacture technology of semi-product. Otherwise, it had excellent low heat build-up and good rolling resistance. It was an ideal material for the shoulder wedge compounding of all-steel radial tyre. |
