In this work, a cationic waterborne epoxy acrylic resin (WCEA) was synthesized from bisphenol an epoxy resin, acrylic acid, acrylic acid, hydroquinone as an inhibitor, and N, N-dimethylbenzylamine (DMBA) as a catalyst. The changes of NCO groups and acid value during the synthesis process were measured by chemical titration method, and its Fourier Transform Infrared (FTIR) spectra were investigated. The results indicate that the acidified waterborne resin has great water solubility and storage stability after grafting the half-blocked isocyanate.
