preparation example Construction

[0042] The preparation method of this kind of inorganic coating comprises the following steps:

[0043] Step 1, under stirring state, mix deionized water and hydroxyethyl cellulose; stir under new stirring state until hydroxyethyl cellulose is completely dissolved to obtain hydroxyethyl cellulose liquid;

[0044] Step 2, under stirring state, mix the hydroxyethyl cellulose liquid, the dispersant and the defoamer evenly to obtain the dispersion liquid;

[0045] Step 3: Mix the dispersion liquid, titanium dioxide, superfine ground calcium carbonate, talcum powder and negative ion coating additives evenly under the stirring state, and obtain the negative oxygen ionic liquid after stirring under the new stirring state;

[0046] Step 4: Mix the negative oxygen ionic liquid, odor-cleaning emulsion, inorganic modified silicate, water resistance agent and viscosity stabilizer evenly under stirring to obtain a stable liquid;

[0047] Step 5, adjusting the viscosity of the stabilized s...

Abstract

The invention discloses inorganic coating, and relates to the technical field of inorganic coating. The inorganic coating comprises the following raw materials by weight: 0.17-0.37 part of hydroxyethyl cellulose; 0.48 to 1.48 parts of a dispersing agent; 4.86 to 10.46 parts of titanium dioxide; 26.32 to 32.32 parts of superfine ground calcium carbonate; 5.22 to 10.44 parts of talcum powder; 1.24 to 2.42 parts of a negative ion coating additive; 5.24 to 10.42 parts of an odor removing emulsion; 12.24 to 20.24 parts of inorganic modified silicate; 1.44 to 2.64 parts of a viscosity stabilizing agent; 0.50 to 1.50 parts of a defoaming agent; 0.25 to 1.0 part of a water-resistant agent; 16.24 to 36.24 parts of deionized water; 0.5-1.0 part of a mildew preventive. The invention also discloses apreparation method of the inorganic coating. The inorganic coating has the characteristics of continuously releasing negative oxygen ions, removing peculiar smell of the coating and purifying air. Thecoating can continuously release anions to remove harmful gases such as formaldehyde, ammonia and benzene, can resist and inhibit bacteria, and can prevent coating hardening.

Description

technical field [0001] The invention relates to the technical field of inorganic coatings, in particular to an inorganic coating 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. Due to its high performance, it is widely used in daily life fields such as architecture and painting. [0003] Inorganic coatings are inorganic polymer coatings composed of inorganic polymers and dispersed and activated metals, metal oxide nanomaterials, and rare earth ultrafine powders. They can quickly react with iron atoms on the surface of steel structures to form a dual protective effect of physics and chemistry. , the inorganic polymer anti-corrosion coating that is firmly combined with the substrate through chemical bonds, has no pollution to the environment, has a long service life, and its anti-corrosion performance has reached...
