The modified epoxy acrylate resin was prepared under a certain temperature with nonionic surfactant

epoxy resin E-20 and acrylic acid. Afterwards

the UV-curable waterborne epoxy emulsion was obtained by phase inversion method. The choices of raw material

reaction condition and emulsifying process were optimized. The comprehensive performance analysis

especially the particle size of emulsions as well as the electrochemical performance and salt-spray corrosion of paint films under different conditions (such as the types of epoxy resin and photoinitiator) were carried out. Results showed that the stability of the emulsion and the film performance (including paint film mechanical properties

electrochemical properties and corrosion resistance) would be the best with the selection of epoxy resin E20

light initiator IRGACURE 651

esterification reaction temperature 105℃

reaction time 3 hours
