摘　　要：将液化石油气系统中常用的密封橡胶件丁腈橡胶试样,浸入各种掺混比例的二甲醚与液化石油气混合液中,浸泡不同的时间段后,测试其体积变化率、质量变化率、拉伸扯断强度、拉伸扯断伸长率、硬度、压缩永久变形量等参数,对所得数据进行分析,研究了不同比例的二甲醚掺混液对丁腈橡胶性能产生的影响。The frequently used nitrile rubber samples in LPG system are immerged in DME/LPG mixture with different proportions. After different periods of time, the volume change rate, mass change rate, tensile strength at break, tensile stretch at break, rigidity and permanent compression deformation of the samples are tested. The obtained data are analyzed. The effect of DME/LPG mixture with different proportions on nitrile rubber performance is studied.
