Diatom ooze coating and preparation method thereof

Abstract

The invention discloses a diatom ooze coating which is made of raw materials comprising, by weight, 15-25 parts of water, 0.6-2.6 parts of lignin or lignin derivatives, 10-15 parts of tourmalines, 0.1-0.3 part of silver oxide, 10-15 parts of titanium dioxide, 3-6 parts of precipitated barium sulphate, 5-15 parts of kaoline, 5-10 parts of sea-foam stone powder, 30-45 parts of nano diatomite, 0.5-1.5 parts of palladium, 5-10 parts of nanometer titania, 0.4-0.6 part of leveling agents, 1.5-4 parts of thickening agents, 0.6-1.2 parts of mildew preventives, 1-5 parts of active carbon nanoparticles, 0.5-3 parts of net-flavor emulsions, 8-15 parts of dispersible adhesive powder and 0-3 parts of pigment. The diatom ooze coating is excellent in breathability and moisture absorption, gas ion negatively charged can be released, human body synthesis and vitamin storage can be promoted, and human immune ability is improved; functions of sterilization, mold prevention, deodorization, air purification and fire prevention are achieved; the preparation method is simple, easy to operate and convenient for large-scale production.

Description

technical field [0001] The invention relates to the field of coatings, in particular to a 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.

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 coating is low; the current coatings still have the problems of not being able to reduce the formaldehyde content in the air, anti-mildew, anti-bacterial, poor adhesion of diatom mud coating, and easy powder drop
