均匀剂A78在炭黑/白炭黑并用体系轮胎胎面胶中的应用

Application of Homogenizing Agent A78 in Tire Tread Compound Filled with Carbon Black and Silica

研究均匀剂A78在炭黑/白炭黑并用体系轮胎胎面胶中的应用。结果表明:加入适量均匀剂A78,炭黑/白炭黑并用体系胎面胶的门尼粘度降低,分散性能和加工性能改善,交联密度增大,物理性能提高;成品轮胎的强度性能和耐久性能较好。

In this paper, application of homogenizing agent A78 in the tire tread compound filled with both carbon black and silica was studied. The experimental testing results showed that, with the addition of an appropriate amount of A78,the Mooney viscosity of the compound was reduced,the dispersion of fillers was improved, the processing properties of the compound and the physical properties of the vulcanizates were improved, and the strength and durability of the finished tire were better.
