硫化温度及硫化程度对全钢载重子午线轮胎胎面胶性能的影响

Effects of Curing Temperature and Degree on Properties of Tread Compound of TBR Tire

研究硫化温度和硫化程度对全钢载重子午线轮胎胎面胶性能的影响。结果表明:硫化温度越低或硫化程度越小,对硫化胶的物理性能、耐磨性能和滚动阻力性能越有利;硫化温度与硫化胶60℃的损耗因子呈强相关性,硫化程度与硫化胶阿克隆磨耗量呈强相关性;硫黄/硅烷偶联剂/促进剂组成的平衡硫化体系可有效减缓因硫化程度增大导致滞后损失增大的趋势。

The effects of curing temperature and curing degree on the properties of the tread compound of TBR tire were studied. The results showed that,the lower the curing temperature or the lower the curing degree,the more beneficial it was to the physical properties,wear resistance and rolling resistance of the vulcanizate.The curing temperature had a strong correlation with the loss factor at 60 ℃,and the curing degree was strongly correlated with the Akron abrasion. The balanced curing system with sulfur/silane coupling agent/accelerator could effectively slow down the increase of the hysteresis loss due to the increase of curing degree.
