Hereinafter, the environmentally friendly mud paint according to the present invention and a method for producing the same will be described in detail.

The eco-friendly mud paint of the present invention comprises 30 to 60 parts by weight of a functional ceramic material, 10 to 30 parts by weight of a natural or synthetic binder; 0.1 to 0.3 parts by weight of a dispersant; 0.1 to 0.4 parts by weight of a thickener; 0.1 to 0.3 parts by weight of an antibacterial functional additive; 10 to 15 parts by weight of a deodorizing additive; 0.3 to 2 parts by weight of a functional additive; 0.2 to 0.5 parts by weight of other additives; And 10 to 30 parts by weight of water.

Natural mud, loess, elvan, zeolite, diatomaceous earth and wollastonite are used as the functional ceramic material.

The natural mud is a natural mud collected from a beach tidal flat and contains components such as natural minerals, germanium and alumina. Far infrared rays are radiated to energize the physiological functions of cells, generate heat energy to remove harmful substances, and release anions naturally.

Such natural mud may be used alone, and mixed with each of the above-mentioned loess, elvan, zeolite, diatomaceous earth and wollastonite may be used.

The natural mud is dried in a natural state to obtain a moisture content of less than 10%, and then pulverized through a hammer mill and pulverized by ball mill or raymond wheat until the desired particle size is obtained.

According to the present invention, it is preferable that the particle size of the natural mud is pulverized to 500 to 1500 mesh in order to uniformly apply the paint at the time of coating and prevent the thickness of the coating film from falling below a minimum value.

Other grains of functional ceramics, that is, clay, elvan, zeolite, diatomaceous earth and wollastonite are preferably 500 to 800 mesh.

When the particle size is too small, it takes much energy and effort to grind and the productivity is decreased. When the particle size is too large, the smoothness of the paint is lowered and the quality is lowered due to the uneven ridges.

In the present invention, the yellow loess which can be used like a mud is mainly a granite composed of silt-sized particles having a diameter of 0.002 to 0.005 mm and a mineral containing a large amount of iron such as gneiss, mica, quartz, and elvan.

In general, yellow loam contains four enzymatic components: catalase, diphenol oxidase, saccharase, and protease. It contains far more potassium chloride, calcium oxide and various organic compounds due to oxidation and weathering, It is known that it has a photoelectric effect that generates harmful substances by generating, and has a cleansing power and decomposition power.

The yellow loess is used in combination with the mud to form the functional ceramic material of the present invention, and is used in an amount of 10 to 40 parts by weight, preferably 20 to 30 parts by weight based on the total weight of the functional ceramic material.

If the amount of the loess is less than 10 parts by weight, or if it is contained in an amount of 40 parts by weight or more, it becomes difficult to maintain proper adhesion and viscosity.

Quartzite is also mixed with the mud and used in an amount of 10 to 40 parts by weight, preferably 20 to 30 parts by weight.

Such elvanite may be 10 parts by weight or less, too much, and when it is 40 parts by weight or more, it is difficult to maintain proper adhesion and viscosity.

In the present invention, zeolite is a material having a good deodorizing effect and a material rich in far-infrared rays. The color of the mud paint may be undesirably deteriorated in the range of 10 to 30 parts by weight, preferably 13 to 15 parts by weight, based on the total weight of the functional ceramic material. If the amount is more than 30 parts by weight, Color development becomes difficult.

In the present invention, diatomaceous earth is deposited on the ground after the diatoms living in lakes and marine sediments have died. Diatomaceous earth is usually composed of 80 to 90% SiO ₂ , 2 to 4% Al ₂ O ₃ and 2% iron oxide. The size of the diatomaceous earth is in the range of 1 to 1 mm, but usually in the range of 10 to 200 탆. In addition, the porosity reaches 60 to 90% due to fine particulate porosity, and the adsorbability of toxic chemicals such as volatile organic compounds is excellent.

 Since the diatomite has a small specific gravity, it can be used in an amount of 10 to 30 parts by weight, preferably 8 to 10 parts by weight, based on the total weight of the functional ceramic material. When the amount is less than 10 parts by weight, the effect of increasing the adsorptivity is insignificant. When the amount is more than 30 parts by weight, the specific gravity of the paint increases and the adhesion force becomes difficult to secure.

Wollastonite is used with muds for applications where surface strength is particularly required.

The wollastonite may be used in an amount of 10 to 30 parts by weight, preferably 8 to 10 parts by weight, based on the total weight of the functional ceramic material. If the amount is less than 10 parts by weight, the effect of increasing the adsorptivity and increasing the strength is insignificant. When the amount is more than 30 parts by weight, the specific gravity of the paint increases and adhesion becomes difficult to secure.

Wollastonite is also used as an extender pigment for preventing cracking and forming a film feeling during film formation.

It can also be used as a pigment to soften the color of the mud paint.

The binder may be any one or both selected from natural binders and synthetic binder binders.

As the natural binder among the above-mentioned binders, any one or two or more selected from animal proteins such as vegetable oil such as gelatin, sodium silicate and flaxseed oil, natural wax such as beeswax, casein and the like are uniformly mixed.

As the synthetic binder, any one or two or more selected from an acryl-based polymer and a silicone-based polymer are uniformly mixed.

Sodium silicate (water glass) is a dark aqueous solution of alkali silicate salt obtained by melting silicon dioxide and alkali. It can be obtained by melting a mixture of silica sand and soda ash at 1,300 to 1,500 ° C in a low pressure steam cooker. In the air, since the gel-like silicate is precipitated by absorbing carbon dioxide, strong adhesion is exhibited. Therefore, it is used for improving the adhesive strength of the product and can be used in 3 to 6 parts by weight per 10 to 30 parts by weight of the whole natural binder.

In this case, when the amount is less than 3 parts by weight, the adhesion force of the paint is weak, and there is a problem that it is smudged or cracked. The effect of the sodium silicate can be fully enjoyed at about 6 parts by weight and if it exceeds 6 parts by weight, It becomes difficult to secure strength.

In order to increase the adhesive strength, 2 to 5 parts by weight of rosin and 2 to 6 parts by weight of water glass can be used for 10 to 30 parts by weight of the entire natural binder. If it is contained too much, the flowability may be impaired and uniform mixing may become difficult. In addition to gelatin, water glass enhances adhesion of mud paint.

The rosin can function to improve the adhesion and adhesion of the mud paint together with the antibacterial function.

The water glass also functions to increase smoothness.

The mud paint according to the present invention is preferably composed of 3 to 10 parts by weight of an acrylic resin and 3 to 10 parts by weight of a water-soluble silicone oil in order to increase surface strength and waterproof effect .

3 to 10 parts by weight of an acrylic resin and 3 to 10 parts by weight of a water-soluble silicone oil can enjoy a sufficient increase in surface strength and a waterproof effect. If the amount is 10 parts by weight or more, a natural unfavorable problem of a plastic resin may occur.

It is preferable that the dispersant is a natural vegetable polymer chemical product, and the product that is effective for adsorption, crosslinking and aggregating and dispersing fine particles suspended in water, and particularly effective for wet coating viscosity removal and organic dispersion is preferably used.

Cellulose is used as the thickening material. Cellulose is a concept including ethylhydroxyethylcellulose, hydroxymethylcellulose, and carboxymethylcellulose. Generally, cellulose is the main component of higher plant cell wall, which is the polysaccharide which occupies most of the woody part and is also called fibrin (fibrin).

Such cellulose improves the viscosity of the coating material, prevents flowability, and prevents the sedimentation of the pigment. The amount of the cellulose to be added is preferably 0.1 to 0.4 parts by weight. When the amount of the thickener added is less than 0.1 part by weight, it is difficult to control the viscosity of the paint and the pigment added may be settled. When the amount of the thickener added is more than 0.4 part by weight, There is a concern.

Songjin is an antiseptic additive, which is secreted when wood of pine tree is damaged. It is added to maintain antimicrobial action and maintain adhesion after application.

For the antimicrobial action, the amount of the vinegar solution is preferably 2 to 5 parts by weight, and the proportion of water should be relatively reduced by the amount of wood vinegar. If the amount is less than 2 parts by weight, the antimicrobial action is too small and the antibacterial effect is sufficient at 5 parts by weight .

Water is used in an amount of 35 to 45 parts by weight, preferably 10 to 30 parts by weight. If the amount is too small, the flowability of the coating is too weak. If the amount is more than 45 parts by weight, the flowability of the coating is too strong.

The antimicrobial function additive is used in an amount of 0.1 to 0.3 parts by weight, and one or more selected from wood vinegar, rosin, and silver nano can be mixed evenly.

Silver nanoparticles prepared by impregnating silver nanoparticles with silver nanoparticles are used as antimicrobial additives.

A silver solution developed by a new high-tech science of nanotechnology is a silver solution in which pure silver ions (Ag +) with a silver purity of 99.9% or more are aggregated in nanoparticles (nm) and dispersed (colloid state) in purified water It has an excellent effect of decomposing more than 650 kinds of bacteria and removing harmful components, and also removing odors, and maximizing antimicrobiality through a large surface area realized at the nano size.

When the amount of the antibacterial function additive is less than 0.1 part by weight, the antibacterial function is lowered. When the amount is more than 0.3 part by weight, the difference in synergistic effect is insignificant.

The deodorizing function additive is used in an amount of 10 to 15 parts by weight, and any one or more of diatomaceous earth, zeolite, and perlite is used as a mixture.

Such a deodorizing function additive deteriorates the deodorizing function when the amount is 10 parts by weight or less, and the improvement effect is insignificant when it is 15 parts by weight or more.

In order to increase the amount of far-infrared radiation, it may further comprise a sericite or quartz powder having a high sio2 content. Sericite, and quartz function together with the mud powder to increase the far-infrared radiation amount of the paint.

0.2 to 2 parts by weight of the functional additive is used. As the functional additive, charcoal which generates negative ions, tourmaline, bentonite which improves smoothness, phytoncide and the like can be used.

As a functional additive, bentonite is a clay mainly containing montmorillonite, which is a mineral belonging to monoclinic having a crystal structure like mica. Its color is white, gray, light brown, pale green, etc. It has good adhesion and lubrication, and its surface is smooth and its strength is strong. Diatomaceous earth, and zeolite.

The phytoncide is a forest bath oil which is excellent in the effect of the forest bath and harmless to the human body. The phytoncide is a volatile substance that is made by itself to dissolve trees and plants to resist insects and fungi, and is an oil phase liquid containing dozens of components.

The functional additive has an anion release effect less than 0.2 parts by weight and less than 2 parts by weight.

As a result of the anion emission test, it was confirmed that the anion emission amount of the natural paint of the present invention using charcoal, phytoncide and tourmaline mixed was 2,150 ion / cc, and the use of charcoal, phytoncide and tourmaline together resulted in higher anion release effect .

0.2 to 0.5 parts by weight of other additives are used, and any one or two or more selected from a fogging agent, a water reducing agent and a surface strengthening agent are mixed and used uniformly.

The antifoaming agent is an additive for suppressing the formation of bubbles or removing bubbles generated at the time of forming a coating film after painting, and the coating film reinforcement is an additive for enhancing the strength of the coating film surface when the film is formed.

The amount of bubbles generated is less than 0.2 parts by weight and the surface strength is lowered. When the amount is more than 0.5 parts by weight, the effect of increasing bubbles and increasing the surface strength is small.

Hereinafter, the eco-friendly agitation method of each material according to the embodiment of the present invention will be described in detail.

The mixing procedure is as follows. First, when the addition of water, a thickener, a dispersant and other additives is completed, the blender is mixed for a predetermined time with stirring at 100 rpm or less. When mixing is completed for 100 ~ 150 minutes, the blender is stopped and the mud and deodorizing functional additives are weighed according to the blending ratio and then added. The stirring speed is adjusted at a high speed and stirred so that each material is uniformly mixed. After stirring for 100 to 150 minutes at 100 rpm or more, an anionic additive and an antibacterial additive which are functional additives are added.

Further, in order to improve the workability of the paint, a defoaming agent, a film reinforcement and water are further added and stirred, and then a sample is taken and the dispersion state is checked using a particle size meter to complete stirring

The method for producing the eco-friendly mud paint comprises: a first milling step of drying the functional ceramic material to have a water content of less than 10% and then coarse milling using a hammer mill; A second pulverization step of pulverizing the mud pulverized product obtained in the first pulverization step so as to have a particle size of 500 to 1500 mesh; 30 to 60 parts by weight of the natural mud obtained in the second pulverization step, 10 to 30 parts by weight of water; 10 to 30 parts by weight of a natural or synthetic binder; 0.1 to 0.3 parts by weight of a dispersant; 0.1 to 0.4 parts by weight of a thickener; 0.2 to 0.5 parts by weight of other additives; 0.1 to 0.3 parts by weight of an antibacterial functional additive; 10 to 15 parts by weight of a deodorizing function additive and 0.3 to 2 parts by weight of a functional additive are mixed in a stirrer.

In the mixing step, firstly, the water is mixed with water, a thickener, a dispersant, and other additives, and the mixture is first mixed for 100 to 150 minutes with stirring at 60 to 100 rpm.

When the blending is completed for 100 to 150 minutes, the blender is stopped, and the mud, antimicrobial functional additive, deodorizing functional additive and binder are weighed according to the blending ratio, and then the mixture is added.
