| 摘 要： | 以丁腈橡胶为研究对象进行了10~#液压油介质中4种温度两种压缩比的加速老化试验,并对自然贮存12 a的丁腈橡胶材料进行恒压永久变形率测试。采用红外光谱、DSC及TGA对自然贮存12 a后及新制备的丁腈橡胶的分子结构、玻璃化转变温度及热性能进行了对比分析。结果表明:通过加速老化试验方法推算得到的丁腈橡胶贮存寿命可靠性较高,材料贮存12 a后未发生明显老化。

| Abstract: | Accelerated aging test for acrylonitrile-butadiene rubber was carried out with two compression ratios at four different temperatures in 10# hydraulic oil. The molecular structure,Tg and thermal properties of nitrile butadiene rubber before and after storage were characterized by FTIR,DSC and TGA. The results showed that the reliability of the shelf-life deduced by accelerated aging test was high. The aging of acrylonitrile-butadiene rubber after 12 years was not obvious. |
