摘要
Abstract
The modification of coal-based impact polypropylene(PP) 2500H by two organic carboxylate nucleating agents HPN-A and GPN-B were investigated,and the effect of different adding amount on crystallization property,mechanical property and phase morphology of coal-based impact PP2500H were studied.The results showed that comparing with nucleating agent HPN-A,the PP samples which added with nucleating agent GPN-B possessed better crystallization property,tensile strength,tensile strain at break,flexural strength and flexural modulus.When the adding amount of GPN-B was 600mg/kg,the crystallization property and stiffness of sample were best.On the ethylene-propylene rubber particle size and distribution,MFI,Rockwell hardness and yellow index of PP samples,the nucleating agents HPN-A and GPN-B both had little effect.关键词
