Flame-retardant-modified and Application Research Progress of Waterborne Polyurethane
The flame retardant properties of waterborne polyurethane(WPU)could be obtained by different modification methods,which was of great significance for expanding the application field of WPU and improving the fire safety.The different modification methods and the problems faced were briefly described in this paper through the classification of flame-retardant waterborne polyurethane.The application of flame retardant WPU in coatings and new energy materials was summarized,and its future development was prospected.
