含氮、硅、磷、硼元素改性剂改性水性聚氨酯的研究进展OA

This paper introduces the latest progress in the research of modified waterborne polyurethane(WPU)containing modifiers with differ-ent elements at home and abroad in recent years.The improvements of water resistance,flame retardancy,heat resistance and mechanical proper-ties of four elemental modifiers containing nitrogen,silicon,phosphorus and boron were reviewed.It is concluded that multi-element synergy to improve the performance of the shortcomings and strengthen the advantages,so that the performance of the WPU can be comprehensively im-proved,which is an important development direction of WPU in the future.
