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 on 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 con- tent 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.
