Summary:The preparation method for the ultraviolet ray hardened epoxy acrylate extender includes the steps of: adding 0.02 wt.% of hydroquinone as a polymerization inhibitor to 0.4 wt.% of pre-reaction materials composed of 75.0 wt.% of bisphenol A type epoxy resin (epoxy equivalent 184-194, molecular weight=360), 25.0 wt.% of acrylate and stable diethanolamine hydrochloride in a flask provided with a thermometer and an agitator; reacting the reactants under inert gas of N2 at 100-105 degrees centigrade for 7-8 hours; cooling the mixture having acidity of less than 1 to about 60 degrees centigrade; and adding 14.0 wt.% of 1,6-hexanediol diacrylate as a viscosity regulator to control the viscosity of the product at 500-700poise (Brook-field Viscometer, 25 degrees centigrade).
