Recycling method of waste polyurethane elastomer

The invention relates to the technical field of polymer material recycling, and discloses a recycling method of a waste polyurethane elastomer. The method comprises the following steps: (1) dissolving the waste polyurethane elastomer in an organic solvent to obtain a dissolved product; and (2) adding an alcoholysis agent and a catalyst into the dissolved product, and carrying out alcoholysis reaction to obtain a polyol product. According to the recycling method of the waste polyurethane elastomer, the dissolving step is added, the reaction time and the reaction temperature of the alcoholysis step are effectively reduced, the energy consumption is reduced, the operation is simple, complicated post-treatment is not needed, and the product can be reused. The organic phosphorus flame retardant in the polyurethane elastomer is degraded through a special enzymolysis step, so that environmental pollution is avoided. 本发明涉及聚合物材料回收利用技术领域，公开了一种废旧聚氨酯弹性体的回收利用方法。所述方法包括以下步骤：(1)将废旧聚氨酯弹性体溶解于有机溶剂，得到溶解产物；(2)向溶解产物中加入醇解剂和催化剂进行醇解反
