Zusammenfassung:A synthetic method of phosphate modified urethane acrylate comprises the steps of adopting POCl3 and long chain diol to synthesize hydroxyl terminated polymer, using the hydroxyl terminated polymer and excessive diisocyanate to synthesize an isocyanato terminated polymer, and finally grafting the isocyanato terminated polymer by hydroxyl acrylate to generate the phosphate modified urethane acrylate. As the phosphate modified urethane acrylate synthesized by the method in the invention has big functionality and low viscosity, the phosphate modified urethane acrylate can be used in ultraviolet-cured adhesives and is capable of reducing dosage of a reactive diluent and improving the mechanical properties of cured film. The light-cured glue film has excellent flexibility, adhesion force and bonding strength, and can be widely applied to glass and metal base materials for improving the mechanical properties thereof such as the adhesion force and the like.
