| 中文摘要: |
| 研究反式聚辛烯橡胶（TOR）/丁腈橡胶（NBR）并用比对并用胶性能的影响。结果表明：随着TOR用量的增大，胶料的加工性能提高，焦烧时间变化不大，t90延长，硫化胶的邵尔A型硬度和100%定伸应力增大，拉伸强度、拉断伸长率和回弹值总体减小，耐磨性能、耐3#标准油性能和耐低温性能下降；TOR/NBR硫化胶的玻璃化温度升高，低温下的储能模量、损耗模量和损耗因子减小。 |
| 英文摘要: |
| The effect of trans polyoctylene rubber（TOR）/NBR blending ratio on the properties of the TOR/NBR blend was investigated.The results showed that， as the addition level of TOR increased，the processability of the compound was improved，the scorch time changed a little，and t90 was extended. Meanwhile，the Shore A hardness and modulus at 100% elongation of the vulcanizates increased，the tensile strength，elongation at break and resilience generally decreased，and the wear resistance，oil resistance and low temperature resistance decreased.The glass transition temperature of the vulcanizates increased with the increase of TOR percentage，and the storage modulus，loss modulus and loss factor at low temperature range decreased. |
