摘要
研究了橡胶/塑料/填充油比例(R/P/O)、树脂硫化体系对低硬度动态硫化三元乙丙橡胶(EPDM)/聚丙烯(PP)热塑性硫化橡胶(TPV)的硬度和力学性能的影响。获得配方(质量份,橡胶为100份)为:PP为30份;油为80份;酚醛树脂用量为6份;SnCl2为1份。其力学性能为邵尔硬度55 A;拉伸强度6.12 MPa、断裂伸长率553%;达到国外同类产品水平。
The low hardness dynamic vulcanization EPDM/PP TPV was studied in this paper. The optimum formula was as follow (Wt) : EPDM ( 100 ) / PP (30)/oil (80)/resin ( 6 )/SnCI2 · 2H20 ( 1 ). The hardness of the result TPV was Shore A 55. The tensile strength was 6.12 MPa. The elongation at break was 553%.
