研究不同品种的环保填充油替代传统芳烃油(DAE)对丁苯橡胶(SBR)性能的影响.结果表明:不同填充油对胶料内部分子链产生多种作用,导致胶料结构与性能存在一定差异;DAE芳烃含量高、极性较强,填充SBR后胶料玻璃化温度提高,物理性能比填充环保芳烃油的胶料好,但生热较高;环保油填充胶料的性能与DAE填充胶料差别不大,可以通过优化橡胶制品配方消除差异.
In this study, different environment-friendly extending oils were tested in SBR compounds to replace DAE,and their effect on the properties of SBR was investigated. The results showed that,different oils affected the motion of molecular chain and caused the difference of the structures and properties of SBR. Since DAE had more aromatic hydrocarbon and higher polarity,the glass tran-sition temperature of DAE filled SBR was higher than that of environment-friendly oils filled SBR, and the physical properties were better, but the heat build-up was higher. However, the difference of the physical properties of environment-friendly oils filled SBR comparing with DAE filled SBR was quite small, and could be made up by formulation optimization of the rubber products.
