Epoxy oil-based unsaturated ester photocurable resin, preparation method and application thereof, adding hydroxyethyl methacrylate, maleic anhydride and polymerization inhibitor to the reactor, stirring and heating reaction; using vacuum distillation The method comprises the steps of: removing the unreacted small molecule to obtain a hydroxyethyl methacrylate half ester product; further adding an epoxidized fat and a catalyst, a polymerization inhibitor to the reactor, stirring and heating the reaction to form an epoxy grease base. An unsaturated ester prepolymer; a vinyl monomer is added to the resulting epoxy oil-based unsaturated ester prepolymer, and a polymerization inhibitor is added thereto, and the mixture is uniformly stirred to obtain an epoxy resin-based unsaturated ester photocurable resin. The epoxy resin-based photocurable resin synthesized by the invention has high prepolymer functionality, so that the material has high crosslinking density after curing, and has excellent hardness, heat resistance and coating film properties, and can be used for photocurable coatings. |
