摘要
研究了光敏剂诱发ＰＥ光降解机理以及改性淀粉、顺丁烯二酸酐等对填充ＰＥ塑料相态结构的影响；紫外光加速老化过程中试样拉伸强度、断裂伸长率随组成、光照时间的变化关系；认为合理地协调各填充组分的用量和关系，可实现填充ＰＥ塑料紫外光降解性能的可控制性。
The mechanism of photodegradation induced by photosensitizer and the effect of the modified starch and maleic anhydride on the phase structure of PE plastics filled with starch were studied. The relationships of the tensile strength and elongation at rupture and with composition and lighting duration of PE plastics filled with starch were also discussed. The results suggested that the controllability of photodegradation of PE plastics filled with starch in ultraviolet light could be achieved through harmonizing the content and relation of filled components reasonably.
