Water-based primer-topcoat in one type paint

The invention relates to water-based primer-topcoat in one type paint for an exterior wall of a building. Current latex paint for the exterior wall has the problems of poor weather resistance, poor stain resistance, poor color retention, greater labor intensity of workers and high labor cost, as well as the phenomena that a coating film is easy to bulge for forming bubbles or crust to form a skin due to the poor matching property between a primer and a topcoat and the color fading can emerge within a shorter period of time, and needs to be reworked after just a few of years. The invention provides the water-based primer-topcoat in one type paint which comprises epoxy-modified silicone acrylic emulsion and a plurality of auxiliaries, wherein the epoxy-modified silicone acrylic emulsion comprises emulsion total monomers, epoxy resin and auxiliary components, the emulsion total monomers comprise methacrylate type monomers, acrylate type monomer, hydroxyl monomers containing double bonds and organic silicon monomers, the formula of the latex paint is simultaneously optimized, the obtained water-based primer-topcoat in one type paint only needs to perform forming twice during the surface contraction of a base layer of the exterior wall, after a coating is formed, the performances of the primer and the topcoat are simultaneously integrated.
