矿用载重子午线轮胎胎面胶的配方优化

Formulation Optimization of Tread Compound of Truck Radial Tire for Mining

对矿用载重子午线轮胎胎面胶配方进行优化。结果表明:通过调整胎面胶配方体系中炭黑的种类和用量以及硫化体系和活化体系,胶料的加工安全性大幅提高,拉伸强度、拉断伸长率、撕裂强度、抗切割性能和耐磨性能明显提高,压缩疲劳温升降低;采用优化试验配方制备的成品轮胎耐久性能大幅提高,与生产轮胎相比较使用寿命延长,经过6个月的实际道路测试,试验轮胎胎面光滑平整,割口明显减少。

The tread compound formula of truck radial tire for mining applications was optimized.The results showed that,by adjusting the type and amount of carbon black in the formula system,as well as the vulcanization system and activation system,the processing safety of the obtained compound was greatly improved,the tensile strength,elongation at break,tear strength,cutting resistance and wear resistance were also significantly improved,and the compression fatigue temperature rise was reduced.The durability of the finished tire prepared with the optimized test formula was greatly improved,and the service life was increased compared with the production tires.After 6 months of actual road test,the tread of the test tire was smooth and flat with significantly fewer cuts.
