Problems solved by technology

[0003] The current inorganic coatings are basically silicate film-forming substances, which have poor water resistance and cannot be washed away by rainwater for years and months when applied to the exterior wall. If the rain lasts for a long time, the exterior wall coating is prone to air bubbles , easy to fall off after drying, causing mottled exterior walls, and easy to fall off exterior wall paint is equivalent to falling objects that may fall off at any time, seriously endangering human health.

Description

technical field [0001] The invention relates to the technical field of inorganic paint preparation, in particular to a water-resistant inorganic paint and a preparation method thereof. Background technique [0002] Inorganic paint is a kind of paint with inorganic materials as the main film-forming substance. It is the abbreviation of all-inorganic mineral paint. It is widely used in daily life fields such as architecture and painting. Coatings commonly used in construction engineering are aqueous alkali metal silicate solutions and aqueous dispersions of colloidal silica. The above two film formers can be used to make silicate and silica sol (colloidal silica) inorganic coatings. The inorganic coatings are composed of inorganic polymers and dispersed and activated metals, metal oxide nanomaterials, and rare earth ultrafine powders. The inorganic polymer coating composed of solid body can quickly react with the iron atoms on the surface of the steel structure to form an ino...
