| 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。 |
| 英文摘要: |
| 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. |
