白炭黑在工程机械轮胎胎冠胶中的应用

摘要

The application of silica and coupling agent Si69 in the crown compound of OTR tire was investigated. The results showed that, compared with the traditional crown compound filled with carbon black, when silica was applied to replace part of the carbon black and coupling agent Si69 was added in the compound, the processing properties, physical properties, wear resistance, cut resistance and heat aging resistance of the crown compound were improved, the heat build-up was reduced, and the performance of the ifnished tire crown was improved.%研究白炭黑和偶联剂Si69在工程机械轮胎胎冠胶中的应用。结果表明：与传统炭黑胎冠胶相比，用白炭黑部分替代炭黑并添加偶联剂Si69的胎冠胶加工性能、物理性能、耐磨性能、抗割口增长性能和耐老化性能提高，压缩生热降低；成品轮胎胎冠胶性能改善。
