Abstract:
A water-based polyurethane resin and a method for manufacturing the same are provided. The method for manufacturing the water-based polyurethane includes: a preparation step of a prepolymer, a dilution step of the prepolymer, a water dispersion and chain extension step, and an acrylic synthesis step. The method further includes mixing polyol and polyisocyanate to obtain a prepolymer, and diluting the prepolymer by adding acrylic monomer in the prepolymer. In the water-based polyurethane resin, at least one of the polyhydric alcohol, polyisocyanate, and the acrylic monomer includes a compound with a cyclic structure.
