| Abstract: | 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. |
