Abstract
The invention discloses a high-weather-resistance waterproof exterior wall coating for buildings and a preparation method thereof, wherein the coating comprises the following components: the paint comprises fluorine-silicon modified acrylic emulsion, epoxy modified acrylic emulsion, fluorine silane, organic bentonite, silicon oxide, titanium dioxide and auxiliaries, wherein the auxiliaries comprise a dispersing agent, a wetting agent, a thickening agent, a defoaming agent, a film-forming auxiliary and an antifreezing agent. The preparation method comprises the following steps: firstly, uniformly mixing the organobentonite, the silicon oxide and the titanium dioxide, then adding the fluorosilicone modified acrylic emulsion and the epoxy modified acrylic emulsion, uniformly mixing, adding the auxiliary agent, uniformly mixing, and finally adding the fluorosilane. The high-weather-resistance waterproof exterior wall coating for the building and the preparation method thereof have excellent waterproof performance, are self-cleaning and washable, and are suitable for various external environments.
