Abstract

The invention discloses metal-roofing waterproof paint and a preparation method thereof. The metal roofing waterproof paint comprises the following components, by weight: 100 parts of an emulsion, 20-50 parts of wollastonite, 50-70 parts of heavy calcium carbonate, 10-20 parts of water, and 3-10 parts of auxiliary agents, wherein the emulsion is composed of 20-25 parts of a pure acrylic emulsion and 32-38 parts of a styrene-acrylic emulsion, with the balance being a vinyl acetate-acrylic emulsion. The preparation method comprises: dissolving the auxiliary agents except from a thickening agent in a part of water; adding wollastonite and heavy calcium carbonate; performing uniform stirring; adding the emulsion and performing uniform stirring; and finally adding the left water and performing uniform stirring to obtain the paint. According to the invention, a blended emulsion composed at a certain ratio is adopted to replace the single pure acrylic emulsion, and matches wollastonite, heavy calcium carbonate, and the auxiliary agents, so that the waterproof paint not only can keep excellent low-temperature flexibility and waterproofness, but also has superior mechanical properties.
