| 摘 要： | 以一缩二乙二醇为醇解剂,二月桂酸二丁基锡为催化剂对氨纶废丝进行了醇解。重点分析了醇解时间、催化剂用量、氨纶废丝与醇解剂质量比等工艺条件对回收聚四氢呋喃二元醇(回收PTHF)性能和结构的影响。结果表明,当温度不变时,增加醇解时间、催化剂用量、醇解剂与氨纶废丝比例仅可以在一定程度上提高回收PTHF的收率和纯度。

| Abstract: | Polyurethane fiber waste was degraded with diethylene glycol and dibutyltin dilaurate.The influence of reaction time,amount of catalyst,weight ratio of polyurethane fiber waste and glycolysis reagents and etc on the properties and chemical structure of the recycled polytetrahydrophrane(PTHF) was investigated.It indicated that the yield and the purity of recycled PTHF could be improved to a certain degree with the change of the above conditions. |
