摘　　要：以超高性能轮胎胎面胶的性能指标为基准,在大填充量、大比表面积白炭黑胶料中采用新型硅烷偶联剂NXT等量替代硅烷偶联剂Si69,研究新型硅烷偶联剂NXT的应用效果。结果表明,硅烷偶联剂NXT能够有效改善白炭黑在橡胶基体中的分散性,相应胶料(增大硫黄用量)的Payne效应明显减小,综合物理性能提高,抗湿滑性能显著改善,滚动阻力降低,但干抓着性能也有所降低。The application of new silane coupling agent NXT instead of silane coupling agent Si69 was studied in the tread compound filled with large amount of silica having high specific surface area for the ultra-high performance tire.The results showed that,with silane coupling agent NXT,the dispersion of silica in the rubber matrix was effectively improved,the Payne effect of the rubber compound was significantly reduced with increased amount of sulfur,the comprehensive physical properties were improved,the wet skid resistance was significantly improved,the rolling resistance was decreased,and the dry grip performance was reduced.
