Epoxy acrylate prepolymer and application thereof

The invention provides an epoxy acrylate prepolymer and an application thereof. The prepolymer is prepared from the following raw materials in parts by weight: 2-10 parts of cyclic carbonate, 4-20 parts of binary polyether amine, 50-70 parts of epoxy resin, 10-30 parts of acrylic acid, 0.01-0.1 part of a polymerization inhibitor and 0.1-0.5 part of a catalyst. A preparation process of the epoxy acrylate prepolymer comprises the following steps: (1) preparing an aliphatic dihydroxyl compound; (2) preparing modified epoxy resin; and (3) performing acrylic acid esterification and end sealing. The epoxy acrylate prepolymer prepared by using the method provided by the invention can be applied to ultraviolet curing coatings, can be rapidly cured under ultraviolet light, has high film coating hardness, good adhesive force and excellent flexibility after being cured, also has good acid resistance, good alkali resistance and certain wear resistance, and can also be applied to decoration of printing inks, adhesives as well as metal and plastic surfaces.
