Description

NATURAL INORGANIC MINERALS NON-FLAMMABLE PAINTS AND MANUFACTURING METHOD THEREOF

The present invention relates to a natural inorganic mineral non-flammable paint mainly composed of harmless, non-toxic natural minerals and a method of manufacturing the same, and more particularly, to release harmful substances from a building structure mainly composed of bricks or concrete materials classified as inorganic materials. As well as blocking, it has excellent adsorption and permeability with concrete components, which can further enhance the adhesion and surface strength of the coated coating film, and its excellent breathability prevents the growth of bacteria and fungi that are harmful to humans. The present invention relates to a natural inorganic mineral nonflammable paint having a high-quality color production and environment-friendly functionality such as suppressing gas generation and a method of manufacturing the same.

Building structures mainly composed of bricks or concrete materials classified as inorganic materials include volatile organic compounds, radon, asbestos, carbon monoxide, carbon dioxide, In addition to pollutants such as nitrogen compounds, ozone, fine dust, and floating dusts, it has also acted as a hotbed of harmful substances that cause various environmental problems by containing harmful substances called so-called sick house syndrome that contaminate indoor air through bacteria such as molds and viruses. .

As various building materials, adhesives, paints, etc. are used in building structures mainly composed of bricks or concrete materials classified as inorganic materials, chemicals generated from them are designated as the main culprit of sick house syndrome. There is a need to develop functional building materials that can suppress or eliminate the release of organic compounds on their own.

Paint, which is one of the building materials, is used for the purpose of protecting objects and making aesthetics beautiful. Especially, the protection function of paint is highly dependent on the film-forming factor, so the durability and physical properties of the film are considered to be controllable by the composition of the resin. Must be designed. Functional paints, which are attracting attention in recent years, provide various effects such as far-infrared effect and anion effect using ceramics in addition to the purpose of the basic paints described above, but in the case of conventional functional paints, coating films formed by simply mixing a large amount of inorganic materials Its strength is weakened or the adhesion to the object, in particular, the building structure mainly composed of concrete material has a problem that the use is extremely limited.

The present invention has been made to solve the problems of the prior art, natural inorganic mineral-based non-combustible paint that does not emit harmful chemicals and does not emit toxic gases due to fire and does not emit mold and harmful bacteria And to provide a method for the production thereof.

It is also an object of the present invention to provide a natural inorganic mineral non-flammable paint having excellent properties such as high weather resistance, durability, flame resistance, surface strength, and a manufacturing method thereof.

In order to achieve the above object, the present invention, the first mixing step of preparing a first mixture by mixing and stirring 20 to 30% by weight of the inorganic binder, 0.5 to 1% by weight of the dispersant and 0.5 to 1% by weight of the antifoaming agent and ; A second mixture of 5-15% by weight of titanium dioxide, 1-5% by weight of methyl methacrylate (MMA), and 0.5-1% by weight of a first thickener, to prepare a second mixture. Steps; A third mixing step of mixing and stirring 21 to 57% by weight of calcium carbonate, 0.5 to 2% by weight of second thickener, and 15 to 25% by weight of water to the second mixture to prepare a third mixture. Inorganic mineral-based non-combustible paints are prepared, wherein the first thickener is methylcellulose and the second thickener is characterized in that the leveling methyl cellulose.

As described above, the natural inorganic mineral non-flammable paint and the method for producing the same according to the present invention include inorganic binders of inorganic minerals, titanium dioxide for giving transparency to the paint, and calcium carbonate, which is a neutralizing agent, as a main raw material, and includes substances harmful to the human body. In addition, it does not emit toxic gas because it is not combusted even in the event of a fire, and the use of alkali-based inorganic raw materials prevents the growth of mold and harmful bacteria.

In addition, it has excellent ventilation structure, so there is little swelling phenomenon and penetrates into the inside of inorganic base to form a physical and chemical combination with concrete, resulting in strengthening the surface of the base to provide excellent physical properties such as high weather resistance, durability, flame resistance and surface strength. have.

Hereinafter, a natural inorganic mineral nonflammable paint and a manufacturing method thereof according to the present invention will be described.

Natural inorganic mineral nonflammable paint according to the present invention is 20 to 30% by weight of inorganic binder, 0.5 to 1% by weight of dispersant, 0.5 to 1% by weight of antifoaming agent, 5 to 15% by weight of titanium dioxide, methyl methacrylate (MMA ) 1 to 5% by weight, 1 to 3% by weight of thickener, 21 to 57% by weight of calcium carbonate, and 15 to 25% by weight of water, wherein the thickener is 0.5 to 1% by weight of methylcellulose and leveling methyl cellulose It is made up of 0.5 to 2% by weight of loose.

On the other hand, the method for producing a natural inorganic mineral nonflammable paint according to the present invention is to mix and stir 20 to 30% by weight modified potassium silicate, 0.5 to 1% by weight of a dispersant, 0.5 to 1% by weight of an antifoaming agent to prepare a first mixture The second mixture is prepared by mixing and stirring the first mixing step, 5-15 wt% of titanium dioxide, 1-5 wt% of methyl methacrylate (MMA), and 0.5-1 wt% of the first thickener to the first mixture. Preparing a second mixing step; And a third mixing step of mixing and stirring 21 to 57% by weight of calcium carbonate, 0.5 to 2% by weight of the second thickener, and 15 to 25% by weight of water to the second mixture to prepare a third mixture. The first thickener is methylcellulose and the second thickener is leveling methylcellulose.

The inorganic binder is a one-component building interior and exterior natural inorganic raw material mainly composed of potassium silicate, such as modified potassium silicate. It is an odorless, pollution-free and environmentally friendly material, and is an alkaline natural raw material, which forms harmful bacteria and molds. It has the effect of preventing and sterilizing, and has excellent weather resistance, durability, and flame retardancy. It also plays a role of strengthening the surface strength of the base by penetrating into inorganic base such as concrete and brick to form physical and chemical bonds.

The titanium dioxide, also called titanium dioxide, is a kind of mineral that is harmless to the human body, which is added to foods, and is added to improve the adhesion of the modified potassium silicate, so that it does not generate toxic gas even when it is burned in contact with a heat source. It is hardly shown and can improve the durability, tensile strength, tear strength and the like while giving transparency to the paint itself.

The methyl methacrylate (MMA) is to provide an auxiliary function for enhancing the adhesion of the paint according to the present invention, and to provide flexibility and high modulus of the coating film.

The thickener is a thickener for improving the viscosity of the paint and is divided into a first thickener added to the second mixing step, for example methylcellulose, and a second thickener added to the third mixing step, for example, leveling methyl cellulose. If the added amount is 1% by weight or less, the viscosity is lowered and the adhesive strength of the paint is lowered. If the content is 3% by weight or more, the paint is easily solidified, so the total amount of the thickener is preferably added at 1 to 3% by weight.

The calcium carbonate is produced from marble, calcite, calcite, limestone, chalk, ice tin, clam shell, egg shell, coral, etc. as calcium carbonate, and is used as a neutralizer for paint.

Hereinafter will be described a specific test example of the natural inorganic mineral nonflammable paint according to the present invention.
