Abstract

The invention provides a pure inorganic water-based topcoat, comprising the following components by weight: 45-55 parts of nano-silica sol, 15-30 parts of acicular wollastonite powder, 5-20 parts of aluminum hydroxide, and 5 parts of inorganic mineral pigments. ~20 parts, 5~20 parts of filler, 0.25~5 parts of thickener. The pure inorganic water-based topcoat provided by the invention can solve the problems of poor appearance, easy powder falling and poor scrubbing resistance existing in the existing pure inorganic water-based topcoat. In addition, the present invention also provides a preparation method of the above-mentioned topcoat, and a pure inorganic water-based architectural coating comprising the above-mentioned topcoat and a matching primer.

Description

technical field [0001] The invention belongs to the technical field of architectural coatings, and in particular relates to a pure inorganic water-based finish paint, a preparation method thereof and a pure inorganic water-based architectural coating. Background technique [0002] At the end of the last century, with the improvement of people's living standards and the enhancement of environmental protection awareness, people have paid more and more attention to the hazards of solvent-based architectural coatings, and thus turned to the development of water-based architectural coatings - latex paints. However, the film-forming substances of latex paints are still It is a potentially harmful organic polymer, and water-based must be compatible with organic additives such as film-forming aids, wetting agents, thickeners, bactericides, and antifreeze agents, resulting in a large amount of sewage and solid waste during the production process. And the pollution of organic waste ga...
