| 中文摘要: |
| 研究硫化体系对丁苯橡胶（SBR）/天然橡胶（NR）并用胶性能的影响。结果表明：当硫化体系的总有效硫质量分数为0.86时，在硫化剂S-80用量为0.8份、促进剂TMTD用量为0.4份、硫化剂DTDM-80用量为1.5份时，并用胶的综合性能最佳，适用于大多数橡胶制品的生产；在促进剂TMTD的用量为0.4份，硫化剂S-80和DTDM-80的配比对并用胶的物理性能和耐热老化性能均有很大影响，通过调整S-80和DTDM-80的用量，可以得到适用于不同场合的、综合性能优异的SBR/NR并用胶。 |

| The effect of curing system on the properties of SBR/NR blends was studied.The results showed that，when the effective sulfur mass fraction in curing system was 0.86，the amount of curing agent S-80 was 0.8 phr，the amount of accelerator TMTD was 0.4 phr and the amount of curing agent DTDM-80 was 1.5 phr，the comprehensive properties of SBR/NR blends were the best，which was suitable for the production of most rubber products.When the amount of accelerator TMTD was 0.4 phr，the content ratio of curing agent S-80 and DTDM-80 had great influence on the physical properties and heat aging resistance of the blends.By adjusting the amount of curing agent S-80 and DTDM-80，SBR/NR blends with excellent comprehensive properties could be obtained. |
