| 中文摘要: |
| 研究多功能橡胶硫化活性剂ZH-73对子午线轮胎胎面胶硫化特性、加工性能、物理性能和动态力学性能等的影响。结果表明：加入2份硫化活性剂ZH-73，混炼胶的门尼焦烧时间略缩短，t90延长，流动性提高，加工性能改善；硫化胶老化前后物理性能相当，60 ℃的损耗因子明显减小；成品轮胎耐久性能提高，滚动阻力系数降低。 |
| 英文摘要: |
| The effect of multifunctional rubber curing activator ZH-73 on the curing characteristics，processability，physical properties and dynamic mechanical properties on the tread performance of radial tire were investigated.The results showed that，after adding 2 phr of multifunctional rubber curing activator ZH-73，the scorch time of the mix was slightly shortened，t90 was prolonged，the flow performance and the processability were improved.The physical properties of vulcanizate before and after aging were equivalent，the dynamic mechanical properties were improved.The loss factor of 60 ℃ was decreased obviously，and the rolling resistance coefficient was reduced. |
