Abstract: A polyurethane resin and a method for manufacturing the same are provided. The method includes the following steps: mixing a polyester polyol, a polyether polyol, a first chain extender, diisocyanate, and a mixed solvent for polymerization, so as to obtain a prepolymer; and adding a second chain extender into the prepolymer for chain extension, so as to obtain the polyurethane resin. The mixed solvent includes diethylformamide and methyl ethyl ketone, and a mass ratio of the diethylformamide to the methyl ethyl ketone in the mixed solvent ranges from 0.45 to 1.80. Based on a total weight of the polyurethane resin being 100 wt %, a total added amount of the first chain extender and the second chain extender ranges from 0.9 wt % to 2.5 wt %.
