添加型光降解聚乙烯塑料性能研究
Study on Properties of Additive Photodegradable Polyethylene
摘要
Abstract
The additive photodegradable polyethylene (PE) plastic bags were exposed to xenon-arc light source,then the tensile properties and thermal oxidative stability of the PE samples with different contents of degradation masterbatch were investigated.The mechanical experimental results show that:with the increasing content of degradation masterbatch,the tensile strength and elongation at break of the samples decrease.The retention rates of elongation at break of the degraded sample containing 60％ degradation masterbatch reach 2.04％ (transverse) and 5.45％ (portrait),and the sample features better using performance and degradation performance.The test results of thermal oxidation show that:with the increasing content of degradation masterbatch,the initial weight loss temperature of the samples after photodegradation decreases,and the thermo-oxidative stability difference before and after photodegradation increases.关键词
