| 摘 要： | 采用母料法分别制备了含硬脂酸铈(CeSt4)、硬脂酸铁(FeSt3)、N,N-二丁基二硫代氨基甲酸铁(FeDBC)、硬脂酸锰(MnSt2)和N,N-二丁基二硫代氨基甲酸镍(NiDBC)等5种光敏剂或光敏调节剂的线型低密度聚乙烯(LLDPE)薄膜,并对所制备的LLDPE薄膜进行了高压汞灯法人工加速老化实验.通过力学性能测试和扫描电镜分析探讨了不同PE薄膜的光降解性能.结果表明,所选用的4种光敏剂对LLDPE薄膜均具有明显的光敏化作用效果,其光敏化活性的大小顺序为FeSt3＞CeSt4＞MnSt2＞FeDBC.相反,NiDBC对LLDPE薄膜则表现出明显的抗紫外老化作用,可作为LLDPE薄膜的光敏化调节剂使用.

| Abstract: | Five different linear low-density polyethylene(LLDPE) films containing CeSt4,FeSt3,FeDBC,MnSt2 and NiDBC were prepared from their master batches respectively.The artificial accelerated ageing test of the prepared LLDPE films was performed using a high pressure mercury lamp.The photo-degradabilities of the LLDPE films were investigated by mechanical measurement and scanning electron microscopy(SEM) analysis.The results show that CeSt4,FeSt3,FeDBC and MnSt2 possess obvious photosensitization on LLDPE photo-de... |
