【摘要】 以二苯基硅烷作改性剂制备了改性白炭黑，研究了二苯基硅烷用量对白炭黑补强SBR性能的影响。结果表明，加入二苯基硅烷后，SBR胶料焦烧时间、工艺正硫化时间及最高转矩均明显增大，最低转矩逐渐减小；加入二苯基硅烷对SBR硫化胶力学性能有一定的改善作用；当用量为2份时，SBR硫化胶综合力学性能较好。随着二苯基硅烷用量的增大，SBR硫化胶0℃损耗因子tanδ略有增大，60℃损耗因子tanδ略有减小；白炭黑在SBR中的附聚体尺寸明显降低；当其用量为1份时，白炭黑附聚体尺寸达到最小值9.46μm。更多还原

【Abstract】 Modified silica was prepared with diphenysilane as modifier, and the effect of the amount of diphenysilane on the properties of SBR reinforced with silica was studied. The results showed that the scorch time, curing time and the maximum torque of SBR compounds increased significantly, while the minimum torque decreased gradually after adding diphenylsilane; The mechanical properties of SBR vulcanizate were improved by adding diphenylsilane, when the dosage was 2 phr, the comprehensive mechanical properties of SBR vulcanizate were better. With the increasing of diphenylsilane content, the tanδ at 0℃ of the vulcanizations increased slightly, but the tanδ at 60℃ of the vulcanizations decreased slightly. The agglomeration size of silica in SBR decreased significantly, the minimum agglomeration size of silica reached 9.46 μm when the diphenylsilane dosage was 1.0 phr.更多还原
