The invention discloses a high-weather-resistance inorganic waterproof stone-like paint which comprises a component A and a component B. The
mass ratio of the component A to the component B is 1: (1.3-1.7). The component A is prepared from the following components in parts by
mass: 600 to 800 parts of
polymer acrylic
emulsion, 100 to 200 parts of waterborne
polyurethane dispersion, 1 to 3 parts of bactericide, 1 to 3 parts of
cellulose, 3 to 6 parts of hollow
fiber, 3 to 6 parts of polycrystalline
mullite fiber, 1 to 3 parts of defoaming agent, 1 to 3 parts of
guar gum, 1 to 2 parts of pH
regulator and 100 to 200 parts of water; the component B is prepared from the following components in parts by
mass: 50 to 150 parts of high-
alumina cement, 50 to 100 parts of
calcium carbonate, 600 to 800 parts of sintered color sand, 50 to 100 parts of resin sheets and 3 to 10 parts of
zinc borate. On the basis, the invention further discloses a preparation method of the high-weather-resistance inorganic waterproof stone-like paint. The high-weather-resistance inorganic waterproof stone-like paint has waterproof performance and stone-like decoration performance, a
coating of the high-weather-resistance inorganic waterproof stone-like paint has excellent physical and chemical properties such as
aging resistance, flexibility and cohesiveness, is provided with certain breathable channels and has breathability, and the problems that a traditional waterproof
coating is not breathable and is prone to bulging and falling off can be solved.
