Abstract

The invention proposes a water-based inorganic environment-friendly coating and a preparation method thereof, which solve the problem that water-based coating in the prior art cannot resist acid and alkali and is low in corrosion resistance. The technical solution of the invention is implemented in the following way: the water-based inorganic environment-friendly coating is prepared from the following materials in parts by weight: 10 to 40 parts of silicasol, 20 to 40 parts of polymer emulsion, 4 to 10 parts of nano silicon dioxide powder, 3 to 6 parts of thickener, 0.1 to 0.5 part of mould inhibitor, 0.1 to 0.3 part of defoaming agent, 1 to 3 parts of film coalescing aid, 1 to 10 parts of dispersant, 10 to 30 parts of calcined kaolin, 10 to 50 parts of heavy calcium carbonate, 10 to 30 parts of pigment and 20 to 40 parts of deionized water. The compatibility between the additives chosen by the invention is better, the coating is odorless and smellless, the protection of ecological environments is benefited, the coating has the nature of inorganic matter, and does not contain any organic chemical material or solvent, and during production and application, the coating has the characteristics of no odor and no allergy, which are good for environment and ecology.

Description

technical field [0001] The invention relates to the technical field of coatings, in particular to a water-based inorganic environmental protection coating and a preparation method thereof. Background technique [0002] At present, water-based coatings have gradually been recognized and accepted by users due to their advantages of environmental protection, non-combustibility, and health, and are being widely used in fields such as flooring, construction, wood, concrete surface protection, and metal surface protection. [0003] According to the classification of film-forming substances, water-based coatings can be divided into inorganic, polyurethane, acrylic, epoxy, polyester and other types. Each water-based coating has its advantages and disadvantages. For conventional water-based coatings, there are defects such as poor solvent and chemical resistance, poor acid and alkali resistance and weather resistance, brittle and easy to crack, poor hardness and wear resistance, and ...
