Abstract

The invention provides an inorganic wall paint easy for color matching. The inorganic wall paint is prepared by mixing of the following components by weight: 100 parts of basic white paint, 0.5-0.7 part of a fatty acid derivative surfactant and 0.5-1 part of a color paste, wherein the basic white paint is prepared by mixing of the following components by weight: 25.8-27.8 parts of water, 0.2-0.4 part of ethyl hydroxyethyl cellulose, 0.8-1.0 part of a dispersion stabilizer, 0.2-0.4 part of a defoaming agent A, 12-16 parts of rutile titanium dioxide, 12-14 parts of calcium carbonate, 7-11 partsof calcined kaolin, 22-28 parts of an inorganic potassium silicate solution, 2-4 parts of an acrylic acid-like thickening protective glue, 5-9 parts of an acrylic emulsion, 0.15-0.25 part of a preservative, 0.15-0.25 part of a defoaming agent B and 0.2-0.4 part of a thickening agent. The inorganic wall paint provided by the invention solves the problems that after use of common color paste for color matching, the color is easy to migrate, the color batching properties are poor, and the price is high due to the use of an inorganic special color paste.

Description

technical field [0001] The invention relates to the technical field of architectural decoration functional coatings, in particular to an easy-to-color inorganic wall coating and a preparation method thereof. Background technique [0002] Inorganic coatings are mainly made of alkali metal silicate or silica sol as the main binder, supplemented with a small amount of synthetic resin emulsion, pigments, fillers, additives, etc. Because this type of decoration material has good non-combustibility, anti-mildew and anti-algae properties, environmental protection, air permeability, alkali resistance, and aging resistance, it is increasingly widely used in the field of indoor and outdoor wall decoration. [0003] However, due to the strong alkalinity of the inorganic binder used in inorganic coatings (pH value is generally above 13), the pH value of inorganic coating products is also relatively high, up to 11-12. However, the color paste used in the architectural coating product sy...
