摘要: 摘要:将氧化钙(CaO)母料、稀土光敏剂和聚乙烯(PE)共混吹制成薄膜,通过人工加速老化、自然曝晒实验,采用FT-IR, TG-IR及SEM等分析手段进行表征。结果表明:CaO/PE可环境消纳薄膜具有明显的光降解性能,同时在焚烧处理时,可减少有害气体的产生量,具有热降解性能。

Abstract: Calcium oxide and rare earth metal photosensitive compound were used as fillers to prepare the environmentally degradable CaO/PEfilm.The film was subjected to artificially accelerated and natura exposure agings, and subsequently the environmental degradability was characterized using FTIR, TG- IR, and SEM.Itshowed that the CaO/PE film had both photo and thermal-degradability. In addi- tion, the CaO/PE films discharged little poisonous gases when incinerated.

Key words: calcium oxide; , rare earth metal photosensitive pound, polyethylene, environmental degradability, light degradability, heat degradability
