摘　　要：反应型聚氨酯热熔胶因其性能优异、适用范围广等特点正逐渐替代传统的胶粘剂。鉴于人们对可持续发展理论的认识深化,从非石油基的生物质衍生物出发制备可循环使用的聚氨酯热熔胶已成为科学家们现阶段亟待解决的目标。本文综述了近几年国内外在新型多元醇材料(生物基、二氧化碳基)开发以及反应型聚氨酯热熔胶再加工方面(如利用动态共价键再加工、利用氨基甲酸酯交换再加工)的进展,并对反应型聚氨酯热熔胶未来的发展方向进行了展望。Reactive polyurethane hot melt adhesive is gradually replacing traditional adhesive due to its excellent performance and wide applicability.Given the deepening understanding of sustainable development theory,the preparation of recyclable polyurethane hot melt adhesive from non-petroleum based biomass derivatives has become an urgent goal for scientists at this stage.In this paper,the progress in the development of new polyol materials(bio-based,carbon dioxide based)and the reprocessing of reactive polyurethane hot melt adhesive(such as using dynamic covalent bonds for reprocessing and using amino ester exchange for reprocessing)both domestically and internationally in recent years were reviewed,and the future development direction of reactive polyurethane hot melt adhesive was prospected.
