单酰肼化合物在高性能轮胎胎面胶中的应用研究

Application of Monohydrazide in Tread Compound of High-Performance Tire

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℃时的损耗因子减小,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。

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 the 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,tanδat 60℃decreased,and the flexural cracking grade of the compound decreased significantly,which confirmed 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.
