Abstract

The invention provides a weather-resistant coating. The weather-resistant coating is characterized by comprising 1.5%-4% of nano-titanium dioxide, 15%-30% of potash water glass solution, 25%-35% of white carbon black, 5%-19% of glycollic acid aqueous solution, 0.5%-3% of malic acid, 1%-3% of superfine aluminum silicate, 5%-10% of perlite, 1.5%-5% of silicone acrylic emulsion and the balance water. The mass fraction of the potash water glass solution is 50%-80%, and the mass fraction of the glycollic acid aqueous solution is 15%-25%. The weather-resistant coating has good water resistance, fire resistance, weather resistance and bonding power, good abrasion resistance is achieved, and the effect for photocatalytic degradation of nitric oxide is quite good. The invention further provides a preparation method of the weather-resistant coating.

Description

technical field [0001] The invention belongs to the technical field of chemical coatings, and in particular relates to a photocatalyst coating and a preparation method thereof. Background technique [0002] Combining photocatalyst nano-titanium dioxide with coating materials to prepare coatings with photocatalytic effects, which can be applied to road surfaces, isolation piers, road edges, railings, etc., can effectively absorb and decompose automobile exhaust, and will be the key to controlling more and more automobile emissions The application direction of the pollution caused by the exhaust gas. At the same time, water-based inorganic coatings use water as the medium, and have a series of advantages such as non-toxic, odorless, free of volatile and other organic substances, convenient construction, rich raw material resources, and low prices. Water-based inorganic coatings have the advantages of high hardness and good wear resistance, but the biggest disadvantages of wat...
