β成核剂对聚丙烯管材性能影响的研究

Effect of β Nucleating Agent on Crystallization and Mechanical Property of Polypropylene Tube

研究了β晶型成核剂及其用量对聚丙烯管材力学性能的影响,并对其进行了正交偏光显微镜观察以及DSC分析。研究表明:加入β成核剂后,聚丙烯晶型由α转变为β,韧性大大增强,且用量在0.1%时达到最大值。

β-crystal nucleating agent and dosage on the mechanical properties of polypropylene tubes,and its orthogonal polarizing microscopy and DSC analysis.Studies show that：with β nucleating agent,the polypropylene crystal of α into β,toughness greatly enhanced,and the amount of 0.1% of the maximum.
