白炭黑分散剂对集成橡胶性能的影响

研究白炭黑分散剂对集成橡胶（SIBR）性能的影响。结果表明：与未加白炭黑分散剂相比，加入白炭黑分散剂的SIBR胶料门尼粘度减小，t¹⁰延长，t⁹⁰缩短，剪切储能模量和剪切损耗模量减小，损耗因子增大；硫化胶的拉伸强度和撕裂强度增大，白炭黑分散性提高；当白炭黑分散剂用量为4份时，SIBR胶料的综合性能最优。;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
