| 中文摘要: |
| 研究硫化体系加料方式对天然橡胶（NR）/顺丁橡胶（BR）并用胶性能的影响。结果表明：NR/BR并用胶的撕裂强度受硫化体系加料方式影响较大，邵尔A型硬度、拉伸强度和拉断伸长率对硫化体系的加料方式容忍度较高；当氧化锌、硬脂酸和硫黄全部加入BR相中时，NR/BR并用胶的耐磨性能好且大应变下的动态损耗低，综合性能较好。 |
| 英文摘要: |
| The effect of the feeding methods of vulcanization system on the properties of natural rubber（NR）/butadiene rubber（BR） blends was studied.The results showed that the tear strength of NR/BR blends was greatly affected by the feeding mode of the vulcanization system，while the tolerance of Shore A hardness，tensile strength and elongation at break was relatively high.When zinc oxide，stearic acid and sulfur were all added into BR phase，NR/BR blends had good wear resistance，low dynamic loss under large strain，showing good comprehensive performance. |
