| Abstract: |
| 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. |
