| 中文摘要: |
| 研究国产稀土异戊橡胶（IR）与天然橡胶（NR）并用对胶料性能的影响。结果表明：随着IR用量的增大，NR/IR胶料的门尼焦烧时间和t90逐渐延长，MH-ML逐渐减小；炭黑分散性不变，IR与NR的相容性良好；硫化胶的邵尔A型硬度和撕裂强度逐渐减小，300%定伸应力和回弹值呈下降趋势，压缩生热降低，耐屈挠性能提高；当NR/IR并用比小于50/50时，胶料的综合性能较好。 |

| The properties of NR/domestic IR blend were investigated.The results showed that the compatibility between IR and NR was good.As the addition level of IR increased，the Mooney scorch time and t90 of NR/IR compound extended gradually，MH-ML decreased gradually，and the dispersion of carbon black unchanged.The Shore A hardness and tear strength of vulcanizate decreased gradually，the modulus at 300% elongation and resilience tended to decrease，the compression heat build-up decreased，and the flexing resistance was improved.When the NR/IR blend ratio was less than 50/50，the comprehensive properties were better. |
