The invention relates to an aqueous paint for wooden wares and a preparation method thereof. The paint of the invention is characterized by comprising acrylic acid modified aqueous polyurethane dispersion. The aqueous polyurethane has good low-temperature resistance, flexibility and wear resistant property, no environmental pollution, but poor water resistance. By compositely modifying the aqueous polyurethane, the property of the polyurethane can be improved, and the polyacrylate has better water resistance, chemical resistance and weather resistance. Thus, the water paint for wooden wares prepared by organically combining the polyurethane and polyacrylate not only has the original superior property of PU, but also has increased water resistance, ultraviolet light aging resistance, and the like.
