Problems solved by technology

At present, most of the anti-corrosion coatings on the market are organic anti-corrosion coatings composed of organic resin emulsion as the base material, plus fillers and anti-corrosion pigments. This organic anti-corrosion coating causes serious pollution to the environment.
[0004] Although the existing inorganic anti-corrosion coatings use inorganic materials as the main film-forming substance, most of them will be modified by adding organic components, or directly adding some organic additives, which does not conform to the concept of green environmental protection; and the anti-corrosion of a few pure inorganic components Coating, its anti-corrosion performance, adhesion, coating strength and other properties are often mediocre, and it is difficult to meet the needs of industrial applications

Description

Technical field [0001] The present invention belongs to the field of inorganic coating, and more particularly to an inorganic anticorrosive coating and a preparation method thereof. Background technique [0002] The high-speed development of modern world economic leap and world industrialization has led to a sharp deterioration of the earth environment, and severe pollution threatens human living space. "Green", "Environmental Protection" is to highly attach great importance to the requirements of the coating industry after ecological environment, and also the development direction of coatings. Inorganic coatings are all inorganic mineral coatings, which have natural environmental properties, with most of the same production costs, difficult to achieve aging and certain physical chemical properties, making inorganic coatings have better technical and economic performance and application prospects. [0003] Anti-corrosion coating, generally divided into conventional anticorrosive ...
