Structure and Properties of UV-Curable Waterborne Polyurethane/Acrylate Composite Resin

UV-curable waterborne polyurethane/acrylate (WPUA) composite resin was prepared, and its properties were compared with those of waterborne polyurethane resin. Results showed that the particle size distribution of the compounding resin was broader, and the compatibility of two phases in resin system became better after adding the acrylate into polyurethane. Moreover, water and alcohol resistances, and mechanical properties of composite resin were superior to those of waterborne polyurethane resin. Comprehensive properties of resin film were the best when photoinitiator amount is 3% of resin.
