硅烷偶联剂KH-792对白炭黑／环氧化天然橡胶复合材料性能的影响

研究硅烷偶联剂KH-792对白炭黑／环氧化天然橡胶（ENR）复合材料性能的影响。通过硫化特性测试和红外光谱分析发现，ENR与白炭黑和硅烷偶联剂KH-792之间发生了反应。试验结果表明：硅烷偶联剂KH-792改性白炭黑/ENR胶料的结合胶含量高，硫化胶的抗切割性能和耐磨性能优异；当硅烷偶联剂KH-792用量为白炭黑用量的8%时，其改性效果最佳。;In this study，the effect of silane coupling agent KH-792 0n the properties of silica/ENR composite was investigated. It was found that ENR could react with silica and silane coupling agent KH-792 by the curing behavior test and infrared spectrum analysis. The results showed that，the content of bound rubber of ENR compound filled with silica modified by silane coupling agent KH-792 was high，and the cut resistance and wear resistance of the vulcanizates were good. When the mass ratio of silane coupling agent KH-792 and silica was 8%， the best modification effect was obtained
