摘　　要：研究EPDM/POE不同共混比对胶料硫化特性、力学性能及耐油性的影响。结果表明,随POE用量的增加,MH、ML和MH-ML均呈降低趋势,力学性能、压缩永久变形和硬度均呈增加趋势,拉伸强度保持率和拉断伸长率保持率呈增大趋势;在室温油中浸泡,体积变化率随POE并用量的增多而减小,在高温油中浸泡,体积变化率随POE并用量的增多而增大。The curing characteristics,mechanical properties and oil resistant performance of EPDM/POE were studied.The results showed that with the increasing of POE content,the MH,ML and MH-ML decreased slightly;The mechanical properties,compression set and hardness increased significantly;The tensile strength retention and retention of elongation increased;With the incteasing of POE content,the volume change declined after soaking in oil at room temperature,while the volume change increased after soaking in oil at 100℃.
