Research development of chemical method recovery waste polyurethane at home and aboard
【摘要】 本文介绍了国内外化学法降解、回收废旧聚氨酯的研究进展和降解反应机理 ,以及国外废旧聚氨酯回收管理机构。分别从二元醇、碱、水解、胺、磷酸酯等不同方法讨论了降解反应的优缺点 ,并对我国废旧聚氨酯的回收与处理提出可行性建议
【Abstract】 The research development of recovery waste polyurethane and chemical degradation method was introduced at home and abocrd. Administer organization of recovery waste polyurethane. Advantage and disadvantage feature of degradation recation from glycolysis、alkali、hydrolyze、aminolysis、phosphoric acid esters etc. Different methods were discussed. And present a possible propose for recovery and treatment of waste polyurethane in our country.
