It relates to an environmentally friendly and functional aqueous coating composition.

Commercially available synthetic resin emulsion paints include synthetic resin emulsion resins and pigments exhibiting color as the main raw materials, and aqueous paints prepared by adding paint additives such as viscosity modifiers are used.

Since the water-based paints use a diluent as water, there is no unpleasant odor due to fire, toxicity, and organic solvents, and has high alkali resistance and high water vapor transmission rate.

These paints mainly show only the performance of basic paints such as protecting the coated object and giving a beautiful appearance.

However, cement concrete apartments coated with such general water-based paints are absolutely additional work to remove residual chemicals, organic gases, and odors in residential buildings.

An object of the present invention is to provide an eco-friendly and functional water-based coating composition having the effect of maintaining the pleasant environment as well as inhibiting indoor environmental pollution by imparting functionality to neutralize decomposition, deodorization, moisturization, heat retention, ventilation, insect repellent and cement toxicity of pollutants.

It has the effect of disintegrating and has additional functions such as insecticides against insects such as flies and mosquitoes.

Hereinafter, the present invention will be described in more detail.

Eco-friendly and functional aqueous coating composition according to the present invention comprises acrylic emulsion resin, loess, jade, ganban stone, gansumite or mixtures thereof, titanium dioxide, inorganic viscosity modifiers, insect repellent and water in a specific amount.

First, the acrylic emulsion resin is a main raw material of the aqueous coating composition according to the present invention to form a coating film through the coating after curing on a variety of subjects.

The acrylic emulsion resin has various functions such as water resistance and breathability, water absorption and strength, elasticity and pollution prevention, and such an acrylic emulsion resin may be any resin that is commonly used in the art.

The acrylic emulsion resin is used in 30 to 40% by weight based on the total weight of the aqueous coating composition. If the content is less than the above range it is difficult to form a coating film, on the contrary, if the content exceeds the above range, the content of other additives, etc., is relatively reduced, making it difficult to secure the coating film characteristics to be represented in the present invention.

The coating composition according to the present invention comprises one inorganic material selected from the group consisting of ocher, jade, elvan, maculite and mixtures thereof.

These fine pores are formed to give the harmful gas, heavy metals and bacteria adsorption desorption decomposition function has an air purification effect.

The ocher, jade, elvan, gansumite and mixtures thereof are those having an emissivity of more than 0.9 milled to 250 to 300 mesh.

In this case, the term of emissivity is synonymous with the emissivity, and the emissivity of the abnormal black body is set to 1, and the relative emissivity compared with the abnormal black body represented by an object is called the emissivity of the object. On the other hand, radiant energy travels through the air at wavelengths. And only when this radiant energy collides with another object, it actually radiates heat.

The general water paint loses radiant heat because it passes radiation energy, but the water-based coating composition according to the present invention absorbs ocher, jade, elvan and / or macsumite radiation energy in to warm the interior in winter and cool the interior in summer. To save energy.

The one or more inorganic materials, ie, ocher, jade, ganban stone, jade, macksum stone, etc., are natural materials having cohesive properties, good absorbency, excellent dispersibility, and emissivity of 0.9 or more. to be.

Far infrared rays, which have the most beneficial wavelengths (8-11um) among the infrared rays, affect the most basic cells of the human body to promote blood circulation and enhance metabolism and tissue regeneration ability. As a result, the body's immunity can be strengthened to restore health.

In addition, it promotes sweating, pain relief, heavy metal removal, sleep, deodorization, antibacterial, fungal growth prevention, dehumidification, insect repellent, air purification is expected to play a role.

The material that emits the far infrared rays include ocher, jade, elvan and maculite.

Ocher is a honeycomb structure with a large surface, and a large number of spaces have a double layer structure. In this space, far infrared rays are absorbed and stored in a large amount, and when heated, they emit far infrared rays and stimulate molecular activity of other objects. In addition, it quickly absorbs odors harmful to the human body, prevents the growth of fungi, such as mold, harmful to the human body, and has the function of blocking electromagnetic waves.

In particular, ocher has insect repellent, antibacterial effect, and separates and extracts heavy metals in the air such as mercury, lead and cadmium, and cleans the indoor air. In addition, it removes moisture from the room and emits far infrared rays when 60 degrees of heat is applied.

Jade contains calcium and magnesium silicates (quartz, silicate), and similar to the cells that make up human cells, the emanating waves from the jade evenly penetrate human cells and act as a resonant resonance. This has a beneficial effect on maintaining health, such as tissue division, blood circulation, alkalizing of blood.

Elvanite is anhydrous silicic acid and aluminum oxide, contains small amount of ferric oxide, and has excellent antimicrobial ability against various harmful substances due to its porous properties and has excellent antibacterial activity against general bacteria and E. coli.

Specifically, the elvan is composed of more than 30,000 multi-layered porous per cm 3 has a large surface area and serves to adsorb and decompose heavy metal contaminants using capillary expansion. It elutes more than 40 kinds of minerals that energize the human body, which is effective in managing metabolism and skin health promotion.

In particular, the elvan has various effects due to resonance and absorption by far-infrared radiation. That is, it has a function of increasing alpha waves and generating far infrared rays. The alpha wave has a property to distract the mind, to concentrate the mind and far-infrared rays to help the activation of bioenergy and the activation of energy in the human body. Also. Elvanite has strong ion exchange ability with heavy metal ions, which is used as a toxic metal remover for wastewater treatment plants, etc., and has a strong deodorizing effect.

Macsumite is made of silica aluminum, ferric oxide, ferric iron, calcium, manganese, magnesium, etc., and the surface is porous. Especially, far infrared radiation is excellent, and antibacterial, deodorant, and dehumidifying effect are excellent.

The present invention by using the loess, jade, ganban stone, macksum stone that can emit the far infrared rays and adsorb organic compounds, etc. as a finishing material coating composition inside the building to maintain a pleasant environment as well as to suppress indoor environmental pollution Grant.

Compared with general antimicrobial agents, they have a high possibility of contact with bacteria and have excellent antimicrobial ability to decompose bacteria debris.

Third, there is a deodorizing effect of decomposing substances causing odor generated indoors through oxidation and reduction of photocatalysts, thereby improving air quality. This is economical because there is no detachment phenomenon of odor component and no secondary pollution prevention and replacement cost compared to general deodorant.

Fourth, the organic composition or NO _x , SO _x , Cl ₂ , NH _3, etc. attached to the coated surface using the coating composition containing the photocatalyst is decomposed into active oxygen generated by the photocatalyst to naturally disappear. It has a self-cleaning effect.

The photocatalyst, titanium dioxide, is used in an amount of 1 to 15% by weight based on the total weight of the aqueous coating composition. If the content is out of the above range, the above-described effects are not obtained, so it is appropriately used within the above range.
