采用醇解法对废弃冰箱聚氨酯(Waste Polyurethane Foam,WPUF)进行回收处理,获得了可循环利用的再生混合多元醇。考察了不同原料、反应时间、反应温度对醇解效果的影响。通过对醇解产物的羟值、粘度和红外谱图分析得到最佳醇解条件为:采用乙二醇为醇解剂,氢氧化钠为催化剂,固液比为100%WPUF、催化剂用量为1%WPUF,实验温度为197.85℃、反应时间为1 h条件下获得的混合多元醇最佳。

In this study, glycolysis was chosen to treat the waste polyurethane foam (WPUF) from waste refrigerators and regenerated WPUF mixed polyols which could be recycled. The influence of raw material type, reaction time, and the temperature on the glycolysis effect was investigated. The determination of hydroxyl value, the viscosity, and the characterization of infrared spectroscopic analysis suggested the optimum condition are as follows:the ethylene glycol is used as the glycolysis agent, and the sodium hydroxide as the catalyst, the solid-to-liquid ratio is 100%WPUF , the dosage of catalyst is 1%WPUF , the reaction temperature is 197.85℃, and the reaction time is 1 h.
