在不同温度和频率下对BR/SBR硫化胶的阻尼因数(即损耗因子,用tanδ表示)和动刚度进行研究.结果表明:在各个温度下,tanδ和动刚度并未对80～130 Hz的频率表现出很强的依赖性;在80～130 Hz的频率下,tanδ和动刚度随温度的变化而发生规律性改变,tanδ随温度的升高而降低,动刚度则是先减小后增大.%The damping coefficient (tanδ) and dynamic stiffness of BR/SBR vulcanizates at different temperature and frequency were studied. The results showed that, neither tanδ nor dynamic stiffness exhibited strong dependence on the frequency from 80 Hz to 130 Hz. At a given frequency,as the temperature raised,tanδ increased,and the dynamic stiffness reduced firstly and then increased.
