改性滑石粉增强增韧聚丙烯研究
Toughening and Reinforcement of Polypropylene with Modified Talc
摘要
Abstract
Used citric acid as a modifier for surface treatment of talc,the modified talc and polypro-pylene(PP)were prepared by melt blending and obtained a series of PP/talc composites. With infra-red absorption spectrum,scanning electron microscopy(SEM),impact properties test,tensile prop-erties test and other experimental methods,researched the modified talc influence of the internal mi-crostructure,mechanical properties and flow properties to the composites. The results showed that:the talcum powder after citric acid modifing can obviously improve the compatibilitys between talcum powder particle and PP,promote the talcum evenly dispersed in PP matrix,and improved process-ing flow properties,impact properties,tensile properties and other mechanical properties,toughened and reinforced PP.关键词
