The invention relates to the field of coatings, in particular to a water-based acrylic acid energy-storage luminescent coating and a preparation method thereof. The water-based acrylic energy-storageluminescent coating comprises the following components, by weight, 20 to 30 parts of water, 0.1 to 0.3 part of dispersing agent, 0.1 to 0.3 part of a wetting agent, 0.01 to 0.1 part of an antifoamingagent, 10 to 30 parts of rare earth doped aluminate type long-acting luminescent powder, 5 to 10 parts of a luminescent powder pretreatment agent, 30 to 50 parts of an acrylic emulsion, 0 to 20 partsof a filling material, 0.2 to 0.5 part of a thickening agent A and 0.2 to 0.5 part of a thickening agent B. According to the invention, the water-based acrylic acid energy-storage luminescent coatingis prepared by limiting the compatibility of the water-based acrylic energy-storage luminescent coating, so that the hydrolysis stability of luminescent powder is improved, and the obtained water-based acrylic energy-storage luminescent coating is low in VOC content, non-flammable, safe and convenient to construct, high in paint film adhesion, good in weather resistance and high in luminescent intensity, and the afterglow time reaches 12 h or longer.
