Problems solved by technology

Existing coatings use potassium silicate solution as a film-forming substance. Potassium silicate provides excellent adhesion performance, but due to the existence of alkali metal ions, the adhesion of the coating is not enough. At the same time, due to the existence of alkali metal ions, the The water resistance of the paint is low; in addition, the existing film-forming substances have poor air permeability, so that the anti-corrosion, antibacterial, absorbent and other properties added to the paint cannot be fully utilized

Description

technical field [0001] The invention relates to the field of coatings, in particular to a multifunctional inorganic diatom mud coating and a preparation method thereof. Background technique [0002] Coating is a material that can be coated on the surface of an object by different construction techniques to form a solid film with strong adhesion, certain strength and continuity. The film formed in this way is commonly called coating film, also known as paint film or coating, which is composed of three basic substances: film-forming substances, secondary film-forming substances and auxiliary film-forming substances. Existing coatings use potassium silicate solution as a film-forming substance. Potassium silicate provides excellent adhesion performance, but due to the existence of alkali metal ions, the adhesion of the coating is not enough. At the same time, due to the existence of alkali metal ions, the The water resistance of the paint is low; in addition, the existing film...
