摘要
采用熔融共混法制备聚丙烯(PP)/三元乙丙橡胶(EPDM)/滑石粉(Tacl)/(高密度聚乙烯)HDPE共混材料。研究了HDPE对改性PP共混体系力学性能的影响及其原因。结果表明,在PP/EP-DM/Tacl/HDPE共混体系中,HDPE的添加量存在一个饱和值,在这一添加量的前后,韧性和刚性指标曲线有波峰或波谷;不同牌号的2种HDPE,熔融指数高者增韧效果好。
The polypropylene(PP)/ ethylene propylene terpolymer(EPDM)/ talcum(Tacl)/ high-density polyethylene(HDPE) blend is prepared by melt-mixing process.The effects of HDPE on the mechanical performances of modified PP blend are studied.The results show that there is a saturation value of HDPE dosage in the PP/EPDM/Tacl/HDPE blend.Under or above the saturation dosage,the toughness and rigidity index curves appear wave top or bottom.For two different types of HDPE,the higher is the melting index,the better is the toughening effect.
