The preparation method of water-based UV-curable epoxy acrylate with low viscosity was discussed in this paper. The epoxy acrylate was synthesized by epoxy resin, polyethylene glycol diglycidyl ether (PEGDE), polypropylene glycol diglycidyl ether (PPGDGE), acrylic acid, maleic anhydride, and trimethylamine through a method of “ring opening reaction—esterification reaction—neutralization reaction.” The viscosity of synthetic material was low and could be used as the binder to prepare ink-jet ink. The results showed that the comprehensive performance of the prepared water-based UV-curable binder was optimal under the following synthetic conditions: The mole ratio of epoxy group and acrylic acid was 1.05:1, the reaction temperatures was 93 °C, the mole ratio of epoxy group and maleic anhydride was 1:0.9, the reaction temperatures was 90 °C and neutralization was 100 %. The characterization of the product was as follows: the viscosity was 24 mPa·s, UV curing time was 5 s, adhesion index was 1 class, and gloss was 95 Gs. In short, the synthesized epoxy acrylate can be used as binder of ink-jet ink.
