【摘要】 研究了ＥＰＤＭ／ＰＰ共混比、不同牌号ＰＰ、硫化体系、混炼方式和软化剂用量对动态硫化ＥＰＤＭ／ＰＰ共混物性能的影响。研究结果表明，当ＥＰＤＭ／ＰＰ共混比为６５／３５，经一步混炼法制出的共混物的拉伸强度大于８ＭＰａ，扯断伸长率达４００％，撕裂强度为４０ｋＮ·ｍ－１，屈挠寿命大于１０万次，邵尔Ａ型硬度为７０～８０度。软化剂用量在３０份以内为宜。更多还原

【Abstract】 The influence of blending ratio,PP type,curing system,mixing method and softener level on the properties of EPDM/PP TPE was investigated.The results showed that the tensile strength was greater than 8 MPa,the elongation at break was 400%,the tear strength was 40 kN·m-1,the flex fatigue life was more than 100 kc and the hardness (Shore A) was 70～80 when the EPDM/PP was blended with the ratio of 65/35 and prepared with the one step mixing method;30 phr of softener was suitable.更多还原
