摘要
聚乙烯作为一种非极性材料,虽然存在许多优点,但是由于其本身具有一定的染色性、黏接性和亲水性等特点,同时又与其他极性聚合物和无机填料的相容性较差,因此会导致聚乙烯的使用空间受到一定的限制。文章阐述了对聚乙烯进行增强增韧操作的方法,论述了采用微米级的碳酸钙、二氧化钛和纳米级的氮化硅或碳化硅粒子填充LLDPE性能,探究了纳米级无机粒子对聚乙烯的增强与增韧具体过程和实际效果。
Polyethylene is used as a non-polar material.Despite many advantages,the use space of polyethylene is limited by its own chromability,bonding and hydrophilic characteristics,and its poor compatibility with other acute polymers and inorganic fillers.This paper expounds the enhancement of polyethylene,discusses theproperties of LLDPE filled with micron calcium carbonate,titanium dioxide and nano silicon nitride or silicon carbide particles,and explores the specific process and practical effect of nano-scale inorganic particles on strengthening and toughening polyethylene.
