The invention relates to an acrylic acid aqueous dispersion for nanometer pearlescent pigment and a preparation method thereof, specifically to an acrylic acid aqueous dispersion and its preparation method and an application in the nanometer pearlescent pigment. The invention discloses a method for preparing an acrylic acid aqueous dispersion resin and a method for applying the acrylic acid aqueous dispersion resin in the nanometer pearlescent pigment. According to the invention, waterborne modification of an automobile repairing paint is realized, VOC discharge capacity is greatly minimized, and the acrylic acid aqueous dispersion also shows excellent pearlescent features. In addition, the coating has very high specular gloss, fine and soft pearly-lustre, Kok effect and excellent decorativeness.
