| 中文摘要: |
| 研究天然橡胶（NR）/丁苯橡胶（SBR）并用比对胶料性能的影响。结果表明：随着SBR用量的增大，胶料的门尼粘度增大，t90延长，拉伸强度和拉断伸长率减小，耐疲劳性能下降，但耐老化性能、耐油性能、抗切割性能及耐磨性能提升；当NR/SBR并用比为30/70时，胶料的综合性能达到最佳水平。 |
| 英文摘要: |
| The influence of the blending ratio of natural rubber（NR）/styrene-butadiene rubber（SBR） on the properties of the compound was investigated.The results showed that as the SBR content increased，the Mooney viscosity of the compound increased，t90 was prolonged，tensile strength，elongation at break and fatigue resistance decreased，but aging resistance，oil resistance，cut resistance and abrasion resistance were improved.When the NR/SBR blending ratio was 30/70，the comprehensive properties of the compound reached the optimal level. |
