杂化碳化硅填充聚丙烯导热复合材料研究

摘要

Plastic was one of the indispensable materials in daily life,which often used to replace or mimic other material products.The general plastic PP was joined with the auxiliary packing such as SiC,PE wax,SiC whisker,and nano SiC,to improve PP＇s thermal conductivity.The formula was studied by changing the types and composition of packing and making products.The various performances,such as thermal conductivity,tensile properties,vicat softening point and melt index of products,were determined.%本文以PP塑料为基料,加入辅助填料以提高其热导率。本文分为两部分：一是研究并摸索出配方;二是对所得产品的性能进行测定,从而得出结论,通过加入SiC可有效提高热导率,但力学性能有所下降,熔融指数随填料填充量增加而降低。加入PE蜡可改善复合材料的流动性,加入第三组分杂化,可提高材料的热扩散系数。
