Study on Synthesis and Properties of Waterborne Polyurethane Modified by Epoxy Resin
Abstract:
The waterborne polyurethane (WPU) modified by epoxy resin was synthesized by using isophorone diisocyanate (IPDI), poly propylene glycol (PPG-1000), 2,2-dimethylol propionic acid (DMPA) and epoxy resin as the main raw materials. The WPU properties were characterized by TGA, FTIR, and so on. The study shows that when nNCO/nOH=1.4, the mount of DMPA is 5.0%, the emulsifying property of WPU which is modified epoxy resin with high epoxy value is well. And when the mounts of E-20, E-44 are 2.0%, 4.0% respectively, the synthesized emulsion with small size has well stability. The modified WPU which possesses high hardness, low water absorption, good heat resistance and anticorrosion, has a well combination property.
