Abstract:

By using bisphenol-A epoxy resin （E-44） as the basic resin and acrylic acid （AA） as the modifier, solvent-based epoxy acrylate （EA） was synthesized, and the effects of reaction temperature, reaction time, catalyst content and inhibitor content on the AA conversion were discussed. Afterwards, waterborne epoxy acrylate （EB） was synthesized via the reaction of hydrophilic carboxy groups in maleic anhydride （MA） with the hydroxyl groups in EA. The results indicate that, when the mass ratios of the catalyst and the inhibitor to E-44 are respectively 1.5% and 0. 075% , the polymerization results in a AA conversion up to 98.27% at 95℃ for 4. 5h; and that the optimal temperature and time for EB synthesis are respectively 80℃ and 1.5 h. It is also demonstrated by the FT-IR spectra of EA and EB that the formation of EA is due to the ring-opening esterification of AA with E-44, while that of EB is due to the esterification of MA with the hydroxyl groups in EA.

Key words: bisphenol-A epoxy resin, acrylic acid monomer, maleic anhydride, waterborne epoxy acrylate
