摘　　要：介绍了近几年来反应型聚氨酯热熔胶的研究新成果,概述了石油基和生物基反应型聚氨酯热熔胶以及反应型热熔胶的脱除。综述了上述聚氨酯热熔胶所采用的原料、配方和合成工艺条件,并分析其凝胶时间、开放时间、耐热性、拉伸强度和硬度等性能,提出了反应型聚氨酯热熔胶的研究建议。The research progress of reactive polyurethane hot melt adhesive in recent years was introduced.The petroleum-based and bio-based reactive polyurethane hot melt adhesives and the removal of reactive hot melt adhesives were outlined. The raw materials,formulation and synthetic process conditions of polyurethane hot melt adhesives were summarized,and the gel time,open time,heat resistance,tensile strength and hardness were analyzed as well. Then suggestions on the research of reactive polyurethane hot melt adhesive were proposed.
