Modifed epoxy was synthesizrd by reacting diglycol aldehyde with E-44 epoxy resin, then UV-curable epoxy acrylated prepolymer used for coating bamboo and wood was synthesized by reacting modifed epoxy with acrylic acid. The effects of synthesis condition ,such as the kind and dosage of catalyst and reaction temperature etc. have been discussed. The effect of the kind of catalyst on the epoxy yield and producUs viscosity,and the effect of the dosage on the esterifying of epoxy were discussed. The effect of the kind of photoinitiator on the curing speed was also discussed. And the final modifed epoxy acrylate UV-curing coating＇s property was better than the coating without modify.
