Abstract:The synthesis technology of UV curing waterborne epoxy resin was studied.The effect of reaction temperature,time,kind and amount of catalyst,inhibitor,carboxyl and solid content,neutralizer on the synthesis and propety of waterborne epoxy acrylate was discussed.The results showed the optium reaction tempreture of epoxy acrylate was 110 ℃ and that of reaction between epoxy acrylate and maleic anhydride was 80 ℃,reaction time was 5 h,triethylamine used as catalyst and the amount was 0.5%(wt),p-hydroxyanisole used as inhibitor.The synthsis pross was feasible.The prepared resin was waterborne and its performance could meet the requirement for practical appllication.
Keywords:UV curing  waterborne  epoxy acrylate  synthesis
