The present invention discloses an acrylate mono-component waterproof coating material, which comprises the following components, by weight, 50-70 parts of an acrylic acid emulsion, 0.02-0.04 part of a preservative, 5-7 parts of calcium carbonate, 10-20 parts of titanium dioxide powder, 0.1-0.3 part of a thickening agent, 3-6 parts of dibutyl ester, 0.04-0.06 part of an ammonia neutralizer, 2-4 parts of cellulose, 0.01-0.03 part of an anti-foaming agent, 6-8 parts of water, and 1-2 parts of a filler. According to the present invention, the pure acrylate emulsion is added with the high quality p filler and the additives to prepare the mono-component high polymer water-based waterproof coating material, wherein the coating material has characteristics of good impermeability, good adhesion, good flexibility, good whole elasticity and good whole elongation, and the effect that the crack with a width of 2-3 mm is generated on concrete while no water seepage is generated after coating the waterproof coating material can be achieved.
