可降解型淀粉改性聚氨酯材料的研究进展

Research Progress of Degradable Starch Modified Polyurethane Materials

聚氨酯存在着严重的降解问题,聚氨酯制品降解后会对环境造成不利影响,影响其各方面的发展。经过研究发现,以生物基为原料的聚氨酯制品在降解后对环境影响小,绿色环保。综述了淀粉改性可降解聚氨酯的研究进展及现状,同时讨论了国内外淀粉的三种改性方法。

Polyurethane has serious degradation problems,and the degradation of polyurethane products will cause adverse effects on the environment,and affect the development of various aspects.The study found that the bio-based polyurethane products have less burden on the environment after degradation and green.The research progress and status of starch modified degradable polyurethane is reviewed,and three modified methods of starch at home and abroad are discussed.
