摘要
Abstract
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.关键词
