摘要
采用添加型技术路线制备一系列新的光降解 PE 母料,并对其性能和应用进行了研究,结果表明,在加工和使用范围内,它们具有与普通 PE 粒料及其薄膜制品同样的物理、力学性能和热氧稳定性等;而薄膜制品在完成使用功能后,其曝光面达崩解期后,可降解成碎片,紧贴地面,形状如干后的粥皮或变成蚯蚓屎状小颗粒,最终从地面消失。另外,光降解 PE 包装材料产品还符合食品卫生标准,可用于各种食品的包装。
The manufacture of a series of new photodegradable functional PE master batch,as well as their properties and applications were studied.The research result shows that in pro- cessing and application the master batehs have the same physical mechanical properties and heat oxidation stability as that of common PE master batch and its film products.When the exposing surface of the film reaches the stage of disintegration after using and dis- carding,it will disintegrate to fragments sticking to the ground like dried gruel surface or turn to granules like ordure of earththworm,and finally disappear from the ground.Also PE photodegradable packaging materials for various foods meet food hygiene standard.
