摘要
研究了羧酸铈光敏剂及其配合体系的组成及各组分的协同关系和作用,讨论了其配合体系对聚乙烯地膜断裂伸长率、羰基指数和相对分子质量的影响,并进行了农田地膜覆盖应用试验。结果表明,含羧酸铈光敏剂配合体系的聚乙烯地膜具有良好的使用性能和可控光降解性能。
The cerium carboxylate ( CeCar) sensitizer and their mixed systems have been developed and the synergistic effect of various components in the system have been studied in this paper. The influences of the CeCar mixed systems on elongation at break , carbonyl index and molecular weight of LDPE agricultural film were discussed. Application tests of the agricultural films were performed on some farmland. The experimental results showed that LDPE agricultural film containing the CeCar mixed systems possessed good applicabilities and the controlled photodegradation characteristics.
