Beschreibung
Zusammenfassung:	The invention discloses a recovery reutilization method for a polyurethane foam waste material. The recovery reutilization method comprises adding polyurethane foam leftover waste material into a mixed alcoholysis agent, adding proper amount of a catalyst, and performing reaction at 80-210 DEG C under protection of nitrogen, so as to obtain an alcoholysis mixed product after 1-3 h. The alcoholysis mixed product is applicable to production of polyurethane foam. The polyurethane alcoholysis recovery reutilization method is short in reaction period and simple and easy to operate, the recovery product is directly applicable to production of polyurethane foam products, efficient green cyclic utilization of the polyurethane foam leftover waste material is realized, and the method possesses relatively good economic benefit and environment benefit.
