| 中文摘要: |
| 研究对比几种官能添加剂对于平衡高填充白炭黑溶聚丁苯橡胶（SSBR）胶料加工性能和力学性能的改善效果。结果表明：在轮胎胎面胶中添加官能添加剂ProCure D3能够较好地改善白炭黑在SSBR胶料中的分散性以及加工性能和加工安全性，降低胶料门尼粘度，加快胶料硫化速度，提高生产效率，同时改善胶料储存期间门尼粘度的稳定性，进而提高轮胎胎面胶挤出尺寸稳定性，获得稳定的动平衡均一性；官能添加剂ProCure D3可以提高胶料的应力应变性能、耐热老化性能以及耐磨性能，降低胶料动态生热性能，平衡轮胎胎面胶的抗湿滑性能和滚动阻力。 |
| 英文摘要: |
| The effects of several functional additives on the balance of processing properties and mechanical properties of the solution polymerized styrene butadiene rubber（SSBR） compound with high loading silica were studied.The results showed that，with the addition of functional additive Procure D3 in the tire tread compound，the silica dispersion，processing properties and processing safety of the compound were improved，the Mooney viscosity was reduced，and the curing rate and production efficiency were improved. At the same time，the Mooney viscosity during storage was stable，and the dimensional stability of extruded tread increased，so the stable dynamic equilibrium was obtained.By adding functional additive ProCure D3，the stress-strain properties，heat aging resistance and wear resistance of the compound were also improved，and the dynamic heat build-up was reduced.The high loading silica filled PCR tire tread compound with functional additive ProCure D3 had good balance between the wet skid resistance and rolling resistance. |
