| Abstract: |
| The effects of silica dispersing agent on the properties of SIBR compound were investigated.The results showed that， compared to the compound without silica dispersing agent，the Mooney viscosity of SIBR compound with silica dispersing agent decreased，t10 extended，t90 shortened， the shear storage modulus and shear loss modulus decreased，and the loss factor increased.With the dispersing agent， the tensile strength and tear strength of the vulcanizate increased，and the dispersity of silica was improved.When the addition level of silica dispersing agent was 4 phr，the best comprehensive properties of SIBR compound were obtained. |
