摘要
研究了不同硫化体系 ,硫化时间 ,硫化剂的用量 ,共混温度 ,橡塑比 ,填充炭黑和软化剂的用量对动态硫化 EPDM/ PP共混物性能的影响。研究结果表明 :酚醛硫化体系制得的 EPDM/ PP共混物加工性能和力学性较佳 ,硫化时间在 10～ 15 min,硫化剂的用量以完全交联 EPDM为宜 ,共混温度控制在 170℃～ 190℃ ,橡塑比 70 / 3 0～ 5 0 / 5 0 ,填充炭黑在 40份以内 ,软化剂在 2
The effects of different curing systems,curing time,content of curing agents,blending temperature,ratio of rubber to plastics and content of filler carbon and oil on properties of dynamic vnlcanizated EPDM/PP blend were investigated.The results showed that a phenolic resin curing system provides the blends with excellent mechanical properties and processability,10~15min’s curing time and content of curing agents which crosslinked rubher fully were better.When blending temperature was 170℃～190℃,ratio of EPDM/PP was 70/30~50/50,content of filler carbon and oil was within 40phr,20phr,respectivly.blend had better properties.
