Claim 0:
1. A waterborne polyurethane acrylate emulsion, characterized by comprising the following raw material components in parts by weight:
polyurethane acrylate prepolymer 20˜80
polyurethane acrylate oligomer 5˜30
first UV-curable monomer 0˜50
water 50˜70;
preparation of the waterborne polyurethane acrylate emulsion:
mixing a diol oligomer and a polyisocyanate so that they react to obtain a nonionic polyurethane;
reacting the nonionic polyurethane with a second UV-curable monomer to obtain the polyurethane acrylate prepolymer having hydrophilicity;
mixing the polyurethane acrylate prepolymer, polyurethane acrylate oligomer, and the first UV-curable monomer and dispersing them in water to obtain a waterborne polyurethane acrylate emulsion.
