The invention relates to a polyurethane-acrylate emulsion used for a waterborne wood lacquer. The emulsion is characterized in that: the polyurethane-acrylate emulsion for the waterborne wood lacquer comprises water, polyisocyanate, polyether polyol, small molecule polybasic alcohol, hydrophilic polybasic alcohol, hydroxyl-containing crylic acid monomer, neutralizing amine, acetone, N-methyl pyrrolidone, methyl methacrylate, adipic dihydrazide, diacetone acrylamide and azobisisobutyronitrile; the content of all components by mass percent is as follows: water: 50 percent to 60 percent, polyisocyanate: 8 percent to 15 percent, polyether polyol: 6 percent to 9 percent, small molecule polybasic alcohol: 1 percent to 2 percent, hydrophilic polybasic alcohol: 1 percent to 2 percent, hydroxyl-containing crylic acid monomer: 0.1 percent to 1 percent, neutralizing amine: 1 percent to 2 percent, acetone: 3 percent to 6 percent, N-methyl pyrrolidone: 3 percent to 6 percent, methyl methacrylate: 8 percent to 15 percent, adipic dihydrazide: 0.1 percent to 1 percent, diacetone acrylamide: 0.1 percent to 1 percent and azobisisobutyronitrile: 0.05 percent to 0.15 percent. The polyurethane-acrylate emulsion for the waterborne wood lacquer has high drying speed, good water resistance, high impact resistance and excellent abrasion performance.
