白炭黑在全钢载重子午线轮胎胎面基部胶中的应用

Application of Silica in Tread Base Compound of Truck and Bus Radial Tire

研究白炭黑在全钢载重子午线轮胎胎面基部胶中的应用。结果表明,以沉淀法白炭黑全部替代全钢载重子午线轮胎胎面基部胶配方中的炭黑,优化白炭黑和吡咯烷酮用量后,能有效降低轮胎冠部生热和滚动阻力,提升轮胎耐久性能。

The application of precipitated silica in the tread base compound of truck and bus radial tire was investigated.The results showed that,by using precipitated silica to replace all of the carbon black in the formula of tread base compound,and optimizing the dosage of silica and pyrrolidone,the heat build-up and rolling resistance of tire crown were effectively reduced,and the durability of tire was improved.
