| 研究环保型溶聚丁苯橡胶（SSBR）/顺丁橡胶（BR）并用胶与白炭黑的相互作用及其对胶料性能的影响。结果表明：随着BR用量增大，SSBR/BR并用胶的Payne效应增强，白炭黑分散性降低，交联密度和硫化速率增大，拉断伸长率、撕裂强度、回弹值和耐磨性能总体提高，抗湿滑性能降低；与SSBR2564S/BR并用胶相比，端基硅偶联的SSBR72612S/BR并用胶与白炭黑的相互作用较强，白炭黑分散性更好；加入BR可以降低SSBR72612S的门尼粘度，提高SSBR72612S/BR并用胶的物理性能和耐磨性能，降低滚动阻力。 |
| 英文摘要: |
| The interaction between environmental friendly SSBR/BR blend and silica and its effect on compound properties were investigated. The results showed that with increase of the addition level of BR，the Payne effect of SSBR/BR blends was strengthened，and the dispersion of silica decreased，the crosslink density and vulcanization rate increased，and the elongation at break，tear strength，rebound value and wear resistance were overall improved，but wet skid resistance was reduced. Compared with SSBR2564S/BR blend，silane modified SSBR72612S/BR blend had stronger interaction with silica，and the dispersion of silica was better. Adding BR could reduce the Mooney viscosity of SSBR72612S，improve the physical properties and wear resistance of SSBR72612S/BR blend，and reduce rolling resistance． |
