| 中文摘要: |
| 将一种单酰肼化合物（简称DC-01）应用于天然橡胶与顺丁橡胶并用体系胎面胶中，研究DC-01对胎面胶性能的影响。结果表明：添加不超过1份DC-01时，胶料的焦烧时间略缩短，硫化速度略减慢，硫化返原时间延长，物理性能有所提升；胶料在60 ℃时的tanδ减小，胶料的屈挠龟裂等级明显下降，证明添加DC-01对降低胶料的动态生热和提升胶料的耐屈挠疲劳性能具有显著效果。 |
| 英文摘要: |
| Monohydrazide（DC-01） was applied to the tread compound with natural rubber/butadiene rubber blend，and the effect of DC-01 on the properties of tread compound was studied.The results showed that when the amount of DC-01 was less than 1 phr，the scorch time of the compound was slightly shortened，the vulcanization speed was slightly slowed down，the curing reversion time was prolonged，the physical properties were improved，tanδ at 60 ℃ decreased，the flexion cracking grade of the compound decreased significantly.It could proved that the addition of DC-01 had a significant effect on reducing the dynamic heat generation and improving the flex fatigue resistance of the compound. |
