| 中文摘要: |
| 对比传统偶联剂Si69，研究新型偶联剂Si747对白炭黑填充溶聚丁苯橡胶/顺丁橡胶并用胶加工性能及动态性能的影响。结果表明：与偶联剂Si69混炼胶相比，偶联剂Si747混炼胶的门尼粘度增大，门尼焦烧时间及正硫化时间缩短；随着偶联剂Si747用量增大，混炼胶的焦烧时间及正硫化时间缩短，加工安全性降低；在口模长径比为15、直径为1.5 mm、挤出温度为100 ℃的条件下，偶联剂Si747混炼胶挤出胶条的表面较平滑，离模膨胀率较小；偶联剂Si747硫化胶的生热及滞后损失较偶联剂Si69硫化胶明显降低。 |
| 英文摘要: |
| In this study，the influence of new coupling agent Si747 on the processing properties and dynamic properties of silica filled SSBR/BR blend was investigated and compared with traditional coupling agent Si69.The experimental testing results showed that，compared with the compound with coupling agent Si69，the compound with coupling agent Si747 had a higher Mooney viscosity，short Mooney scorch time and cure time.With the increase of coupling agent Si747 amount，the scorch time and cure time were shortened，and the processing safety was reduced.With an extrusion die having an aspect ratio of 15 and a diameter of 1.5 mm，the surface of the extruded compound with coupling agent Si747 was smooth and expansion was low under the extrusion temperature of 100 ℃.It was also found that the heat build-up and hysteresis loss of the vulcanizates with coupling agent Si747 were significantly lower than those with coupling agent Si69，respectively. |
