| 中文摘要: |
| 研究加工助剂莱茵塑分ST和GT对溶聚丁苯橡胶（S-SBR）/BR胶料以及莱茵塑分ST用量对S-SBR/乳聚丁苯橡胶（E-SBR）/BR胶料性能的影响。结果表明，在S-SBR/BR胶料中加入莱茵塑分ST和GT，可以降低胶料的门尼粘度，改善胶料的加工性能，对硫化胶的物理性能影响不大。在S-SBR/E-SBR/BR胶料中加入莱茵塑分ST，可以显著改善胶料的加工性能，提高硫化胶的定伸应力和耐热老化性能；莱茵塑分ST用量为4份时，硫化胶的动态力学性能最佳。 |
| 英文摘要: |
| The influences of the processing aids Aktiplast ST and GT on the properties of S-SBR /BR compound and the additional level of Aktiplast ST on the properties of S-SBR/E-SBR/BR compound were investigated.The results showed that the Mooney viscosity of compound lowered and the processibility improved by adding Aktiplast ST and GT in S-SBR/BR compound resulting in little effect on physical properties of vulcanizate;the processibility of compound improved significantly and the modulus and heat aging resistance of vulcanizate increased;and the vulcanizate with the optimum dynamic properties was obtained by adding 4 phr of Aktiplast ST to rubber compound. |
