摘　　要：研究了注射成型EPDM/PP热塑性硫化橡胶的配方及共混设备对性能的影响。结果表明 :采用双螺杆挤出机制备 ,硫化剂用量为 3份时 ,制得的EPDM/PP的性能较好 ;注射成型试样的拉伸性能好于模压成型试样。The effects of the formula and blending machines on the properties of injection grade EPDM/PP thermoplastic elastomer were discussed. The results showed when the amount of curing agent was 3 phr and the blending was made by twin screw extruder,the comprehensive property of the prepared EPDM/PP was better. Meanwhile,the tensile property of the sample by injection moulding was better than that of the sample by mould pressing.
