The invention discloses a waterborne coating for architectural decoration. The waterborne coating is prepared from the following raw materials in parts by weight: 80-100 parts of vinyl acetate-ethylene copolymer emulsion, 40-60 parts of polyacrylate resin, 15-25 parts of polyurethane, 3-5 parts of nano-attapulgite, 2-15 parts of a halloysite compound, 1-3 parts of rutile titanium dioxide, 2-4 parts of magnesium stearate, 0.5-1.5 parts of lithopone, 20-40 parts of filler, 1-2 parts of polyaniline, 1-2 parts of polyetheretherketone, 0.5-0.9 part of vaseline, 0.2-0.8 part of pine tar, 0.1-0.2 part of octylphenol polyoxyethylene ether, 0.6-1 part of zinc soap salt, 0.2-0.6 part of chlorinated paraffin, 1-2 parts of a thickening agent and 100-180 parts of water. The waterborne coating has super-weather resistance and scrubbing resistance, has the characteristic of deposition prevention, and is also high in adhesion force, good in color spreading effect and excellent in fading prevention effect and decoloring prevention effect.
