Abstract：This paper introduced the chemical composition and properties of solvent-free two component polyurethane adhesives. Compared with the advantages of environmental protection and high efficiency of waterborne polyurethane adhesive， the development process of solvent-free polyurethane adhesive from the first generation to the fifth generation was described. The research direction and achievements of solvent-free two-component polyurethane adhesive abroad in recent years are also summarized. At the same time， the development trend of solvent-free two-component polyurethane adhesive was introduced， and the existing problems and prospects were pointed out.
