摘　　要：对比硅烷偶联剂常温处理和原位改性白炭黑填充氢化丁腈橡胶(HNBR)胶料的性能,并研究不同种类硅烷偶联剂原位改性白炭黑对HNBR胶料性能的影响。结果表明:硅烷偶联剂原位改性白炭黑填充HNBR胶料的门尼粘度降低,加工性能改善,Payne效应减弱,硫化胶的拉伸强度增大,压缩永久变形减小;采用硅烷偶联剂A151或WD70原位改性的HNBR胶料的加工性能和物理性能较好,压缩永久变形较小,改性效果较优。The properties of HNBR compounds filled with silica fillers which were pre-treated by room temperature process and modified through in-situ modification were compared,and the effects of type of silane coupling agent applied in silica in-situ modification on the properties of HNBR compound were investigated. The results showed that,the Mooney viscosity of HNBR compound filled with in-situ modified silica decreased,the processing property was improved,and the Payne effect was weakened. The tensile strength of the vulcanizates increased,and the compression set decreased. The HNBR compound with silica in-situ modified by silane coupling agent A151 or WD70 possessed better processing property, better physical properties and lower compression set, showing good modification effect.
