中文摘要: 聚氨酯泡沫因具有良好的保温、缓冲、化学稳定等性能，在包装、医药、吸声、阻燃等领域有广泛应用。聚氨酯泡沫是由石油基多元醇与异氰酸酯反应而得，对环境污染严重。植物油、木质素、淀粉等生物基材料改性后可替代石油基多元醇制备聚氨酯泡沫，是一种绿色可再生材料。该文综述生物基多元醇的种类、改性方法及应用，展望生物基聚氨酯泡沫材料在食品包装领域的应用前景，旨在为生物基聚氨酯泡沫在食品包装方向的应用提供参考。
Abstract:Polyurethane foam is widely used in the fields of packaging，medicine，sound absorption，and flame retardant because of its good thermal insulation，cushioning，and chemical stability.Polyurethane foam is obtained by the reaction of petroleum-based polyol and isocyanate，which causes serious environmental pollution.Bio-based materials such as vegetable oil，lignin，and starch can replace petroleum-based polyols by modification to prepare polyurethane foam，which are green and renewable.This paper reviewed the types，modification methods，and applications of bio-based polyols，and looked forward to the application prospects of bio-based materials for polyurethane foam in the field of food packaging，aiming to provide reference for the application of bio-based polyurethane foam in food packaging.
