摘　　要：聚乙烯醇缩丁醛(PVB)树脂具有优异的成膜性、光学透明度及较强的柔韧性、弹性、粘结性、抗冲击等性能,广泛应用于陶瓷花纸、涂料、粘合剂、汽车挡风玻璃夹层材料、太阳能电池封装材料等领域,但PVB呈现不可降解特性,大量的废旧PVB树脂的产出极易造成资源浪费和环境污染。如何实现废旧PVB树脂的回收和再利用是当前工程领域内的研究热点。本文简要介绍了PVB树脂的特性及废旧PVB树脂的来源,详细阐述了废旧PVB树脂的回收技术,列举了再生PVB树脂在过滤材料、吸附材料、增韧材料、发泡材料及电化学材料中的应用现状,综述内容为废旧PVB树脂的回收再利用提供了参考。Polyvinyl butyral(PVB)resin has excellent film-forming properties,optical transparency,strong flexibility,elasticity,adhesion,and impact resistance.It is widely used in ceramic flower paper,coatings,adhesives,automotive windshield interlayer materials,solar cell packaging materials,and other fields.However,PVB exhibits non degradable characteristics,and the production of a large amount of waste PVB resin is prone to resource waste and environmental pollution.How to achieve the recovery and reuse of waste PVB resin is a research hotspot in the current engineering field.This article briefly introduces the characteristics of PVB resin and the sources of waste PVB resin,elaborates on the recycling technology of waste PVB resin,and provides examples of the application status of regenerated PVB resin in filtration materials,adsorption materials,toughening materials,foaming materials,and electrochemical materials.The review provides a reference for the recycling and reuse of waste PVB resin.
