摘　　要：对 ＮＲ／ＥＰＤＭ／ＰＰ三元共混体系的硫化剂用量及共混工艺方法进行了系统的研究，分别在研究 ＮＲ／ＰＰ和 ＥＰＤＭ／ＰＰ二元共混体系硫化剂用量的基础上确定了 ＮＲ／ＥＰＤＭ／ＰＰ 三元共混体系硫化剂的用量；基于ＮＲ与ＥＰＤＭ硫化速度有差异的情况下，选择了五种共混工艺方法进行了比较，通过比较选定了共混过程中先加入ＥＰＤＭ、再加入硫化剂总用量的５０％，然后再加入 ＮＲ和余下的硫化剂的分段共混方法。The content of crosslink agent and the blending method of NR/EPDM/PP ternary blending system is systematically discussed. The content of crosslink agent of NR/EPDM/PP is determined on the basis of discussing NR/PP blend and EPDM/PP blend Separately. Due to the difference of the vulcanizate speed of NR and EPDM, five bleding methods to be compared are chosen. In this blending method, first add EPDM, then add half of the content of crosslink agent and finally add NR and the other half of crosslink agent, and the property is satisfactory.
