| 摘 要： | 采用溶液共沉淀法制备了溶聚丁苯橡胶（SSBR）／丁基橡胶（IIR）材料，研究了IIR品种和含量对样品物理机械性能和动态力争性能的影响。结果表明：当IIR质量分数低于10％时，样品的性能变化较小；当IIR质量分数大于20％时，样品的300％定伸应力和扯断强度降低，动态粘弹（DMA）谱图显示玻璃化转变温度由1个变为2个，60℃时tanδ显著增加，提高了样品的阻尼性能。

| Abstract: | Composites of SSBR/IIR were prepared by solution co-precipitation method. The results showed that when the content of IIR was less than 10%, little changed in the performances of the sample,and when the content of IIR was greater than 20% , the modulus at 300% and tensile strength were reduced with the increase of IIR content. From DMA spectra, with the increase of IIR content, the glass transition temperature showed two peaks, and tan δ at 60 ℃ was increased significantly. |
