Manufacturing method of coating agent for preventing sick house syndrome {MANUFACTURING METHOD OF COATING AGENT FOR PREVENTING A SICK BUILDING SYNDROME}

The present invention relates to a method for manufacturing a coating agent for preventing sick house syndrome, and more particularly, by preparing an environmentally friendly illite-wood vinegar-silver nano-adhesive, mixing mud-porous powder composition therewith, and applying it to the inner surface of a building or building interior material. As a result, insulation and thermal properties are improved, and the performance of adsorbing emitted moisture, harmful substances and odors is excellent, and the air permeability of the coated film effectively blocks the propagation of parasitic bacteria and mold on cement walls, as well as volatiles floating in the air. It relates to a method for manufacturing a coating agent for preventing sick house syndrome that can remove even organic compounds (VOCs).

In general, sick house syndrome refers to the appearance of abnormal symptoms in the body when moving into a newly built house, and formaldehyde is a representative substance caused by volatile chemicals among reactions caused by air pollution in the house. . Formaldehyde is a colorless gas with a pungent odor and is soluble in water. It is mainly used as a preservative, raw material for adhesives (construction, furniture industry, etc.) If you use building materials that contain formaldehyde in your new home, it can be released indoors for years.

In addition, chemical substances emitted indoors include xylene, toluene, benzene, organic phosphorus, and combustion inhibitors. Of these, the most problematic is the building interior material, especially vinyl chloride, which is used in ceilings, walls, floor cushions, and seats. It is used a lot.

For the above reasons, many people complain of various symptoms immediately after moving to a new house. Existing allergic diseases such as atopic dermatitis and asthma may worsen, or hives may occur for no particular reason, and irritation of the eyes, nose, larynx, and airway mucosa symptoms appear by For example, symptoms such as sore or itchy eyes, sore throat or coughing appear, and headaches, fatigue, or lethargy may occur. The symptoms caused by the sick house syndrome are more severe in infants and elderly people with weak immunity, and symptoms are aggravated in patients suffering from allergic diseases.

Accordingly, it is possible to reduce the damage by using natural materials for building interior materials or using plywood or finishing materials that have not been treated with formaldehyde, but it is very difficult in reality. As volatile organic compounds, volatile organic halogen compounds such as trihalomethane, trichloroethylene, and tetrachlorethylene, and aromatic compounds such as benzene, are classified as carcinogens and cause severe odor.

1 is a process flow chart showing a method for manufacturing a coating agent for preventing sick house syndrome according to the present invention.

Hereinafter, the manufacturing method of the sick house syndrome prevention coating agent according to the present invention will be described in detail, but this is to illustrate the extent to which a person with ordinary knowledge in the art to which the present invention belongs can easily practice the invention. , This does not mean that the technical spirit and scope of the present invention is limited.

As shown in FIG. 1, in the manufacturing method of the coating agent for preventing sick house syndrome according to the present invention, 3000 g of water is added to 1000 g of illite powder pulverized to 325 mesh or less, and the ball mill (ball mill) for 48 hours A first step of preparing an illite solution by pulverizing with a mill), precipitating illite particles heavier than water for 24 hours, and then separating the supernatant in which the illite particles are transparently dispersed in water; A second step of preparing an illite-wood vinegar mixed solution by mixing 1000 g of the illite solution prepared in the first step with respect to 1000 g of the wood vinegar; A third step of preparing an illite-wood vinegar adhesive by mixing 1000 g of the illite-wood vinegar mixed solution prepared in the second step with respect to 1000 g of a water-soluble acrylic adhesive having a solid content of 20%; A gelatin adhesive was prepared by dissolving 100 g of gelatin in 3000 g of hot water at 80 ° C, and then mixed at a ratio of 1000 g of illite-wood vinegar adhesive prepared in the third step and 200 g of silver-nano aqueous solution to obtain illite -Fourth process of producing wood vinegar-silver nano-adhesive; After washing, drying, pulverizing, and sterilizing sea tidal flat mud, 1000 g of dried mud powder is mixed with 200 g of illite powder, 100 g of bamboo charcoal, 300 g of white charcoal, 100 g of activated carbon, and 100 g of graphite powder to obtain mud- A fifth step of preparing a porous powder composition; Illite-wood vinegar-silver nano-adhesive 1000g prepared in the 4th process was mixed in a ratio of 300g of the mud-porous powder composition prepared in the 5th process, and pulverized and kneaded with a ball mill for 3 hours to cause sick house syndrome. 6th process of manufacturing an anti-coating agent; made including

First, in the first step, 3000 g of water is added to 1000 g of illite powder pulverized to 325 mesh or less, pulverized with a ball mill for 48 hours, and then illite particles heavier than water are boiled for 24 hours. It is a process of preparing an illite solution by precipitating during precipitation and then separating the supernatant in which illite fine particles are transparently dispersed in water. It has a silver value of 2.6 ~ 2.9 and a streak color of white. It is called a 'mysterious mineral' due to its effects such as heavy metal adsorption, antibacterial, and far-infrared radiation. Recently, illite has been used in various fields such as livestock feed, air purification, cosmetic raw materials, interior, and construction flooring.

In the present invention, the dispersion quality of fine particles (colloidal particles, grain diameter of about 0.1 μm) is dispersed using a liquid as a dispersion medium by finely pulverizing illite ore to 325 mesh or less with a ball mill for 48 hours. It is also called sol as it maintains fluidity. If the dispersion medium is water, it is called hydrosol, and if it is an organic solvent, it is called organic sol. and is in a state of being stabilized by the electrostatic action of these charges.

The second process is a process of preparing an illite-wood vinegar mixed solution by mixing 1000 g of the illite solution prepared in the first process with respect to 1000 g of the wood vinegar. The wood vinegar collects the smoke generated when carbonizing wood It is preferable to use at least one wood selected from bamboo and oak as pure photosynthetic natural energy made by re-stabilizing and filtering the crude wood vinegar produced by cooling. The wood vinegar is an acidic liquid with acetic acid as the main component, around pH 3, and it can neutralize harmful substances (formaldehyde, radon, ammonia, hexavalent chromium, toluene, etc.) generated in the strongly alkaline cement curing process or building interior materials. Therefore, it can be expected to relieve skin diseases such as atopy.

The third step is a process of preparing an illite-wood vinegar adhesive by mixing 1000 g of the illite-wood vinegar mixed solution prepared in the second step with 1000 g of water-soluble acrylic adhesive having a solid content of 20%, and mixing in the same ratio as above. As a result, it is possible to obtain an adhesive material with a suitable viscosity, and the water-soluble acrylic adhesive used in the present invention is not particularly limited in its specific type as long as it is harmless to the environment, but when considering adhesion, penetration into interior materials, durability, etc. It was concluded that it is most preferable to use a water-soluble acrylic adhesive having a solid content of 20%.

The fourth step is to prepare a gelatin adhesive by dissolving 100 g of gelatin in 3000 g of hot water at 80 ° C, and then to the illite-wood vinegar adhesive prepared in the third step and 1000 g of silver-nano (Silver-nano) aqueous solution at a rate of 200 g In the process of preparing the illite-wood vinegar-silver nano adhesive by mixing, the present invention is an environmentally friendly gelatin adhesive to uniformly mix the illite-wood vinegar adhesive and the silver-nano aqueous solution prepared in the third step was used.

The gelatin is an incomplete protein that lacks several amino acids nutritionally, and is extracted by boiling animal skin or muscles after treating it with acid or alkali. It is used in the production of and industrially used in a variety of ways. It dissolves in hot water at 80℃ and becomes a colloidal sol, increasing its viscosity, but hardens when cooled to form a gel, which acts as an emulsifier or stabilizer. will do

In addition, in the fourth step, 1000 g of the illite-wood vinegar adhesive prepared in the third step is mixed with a silver-nano aqueous solution at a rate of 200 g. Since it is very important, high-purity silver (Ag) with a purity of 99.99% or higher is electrolyzed in distilled water, and silver ions (Ag ⁺ ) are included in the water at a concentration in the range of 30,000 ~ 100,000ppm (3 to 10% aqueous solution), resulting in ionic silver nano It maintains a stable state as a colloidal aqueous solution, and this silver solution is called colloidal silver.

In general, nano-silver technology is a technology that uses the fact that new properties such as strong antibacterial, sterilization, and deodorization appear when silver (Ag) is broken down to 1/1 billionth of a meter or less. and mix the ionized silver solution with materials or use it directly for sterilization. Since silver itself is not oxidized in air and water, the antibacterial and sterilization life of products coated with silver or mixed with silver solution is semi-permanent. Nano-silver products refer to products manufactured by coating nano-silver particles on products or mixing them with materials.

In fact, the antibacterial and sterilizing effect of silver has been widely known in the East and West for a long time, and it has been scientifically proven that it kills more than 650 disease-causing microorganisms and is safe for the human body. In order to make particles into particles, research on electrolysis or chemical decomposition methods is steadily progressing.

Taking the electrolysis method carried out in the present invention as an example, when power is supplied to a silver plate while water is supplied, the silver plate is electrolyzed and silver ions (Ag ⁺ ) escape and mix with water. to maximize the response surface. However, since silver (Ag ⁺ ) is precipitated as silver chloride (AgCl) in water due to chlorine ions (Cl ^- ) in tap water, there is a concern that the sterilizing power, which is the original property of silver, may be reduced. It is important to conduct electrolysis in ion-free distilled water.

The first strength that can be obtained from the silver nano aqueous solution is a strong antibacterial effect, but in addition, it prevents the growth of bacteria and removes mold to prevent odors, and also blocks electromagnetic waves and water pulse waves due to electrical conductivity, and emits far-infrared rays and negative ions. It is known that there is

Apart from the first to fourth processes, the fifth process involves washing, drying, pulverizing, and sterilizing the sea tidal flat mud, and then adding 200 g of illite powder, 100 g of bamboo charcoal, It is a process of producing a mud-porous powder composition by mixing at a ratio of 300 g of white charcoal, 100 g of activated carbon, and 100 g of graphite powder. Since the tidal flat mud is mixed with corrosive substances such as naturally deposited various seaweed and shellfish, porous mud powder can be obtained through washing, drying, grinding, and sterilization processes. The mud powder is known to have an excellent effect on skin care because it contains a large amount of natural mineral components and has excellent far-infrared radiation and anion emission effects, as well as antibacterial action, moisture and harmful substance adsorption performance.

The mud-porous powder composition is mixed in a ratio of 200 g of illite powder, 100 g of bamboo charcoal, 300 g of white charcoal, 100 g of activated carbon, and 100 g of graphite powder to 1000 g of mud powder. Light powder is a clay mineral in the form of mica belonging to the monoclinic system, and is currently widely applied as a cosmetic material based on the fact that it has various effects such as heavy metal adsorption, antibacterial, and far-infrared radiation.

And charcoal such as bamboo charcoal, white charcoal, and activated carbon added to it is a pure Korean word that means 'fresh power.' , There are countless examples of using it in various places of daily life, such as tombs, temple sites, wells, and house sites. In Donguibogam, it is recorded that tabasheer (bamboo oil) has an excellent effect on stroke and mental and physical stabilization, and bamboo sap is also used as a folk remedy. It is effective for stroke, cough, and tetanus, and bamboo bark is known to be effective for vomiting.

In particular, bamboo charcoal has a specific surface area of about 600㎡/g, which is superior to other woods in adsorption performance, and is known to relieve fatigue while stabilizing the mind and body due to its air purifying action and negative ion generating effect. Charcoal made by carbonizing at a high temperature of more than ℃ and then taking it out of the kiln and covering it with wet ashes and suddenly cooling it. When the same weight, white charcoal has a larger adsorption area than black charcoal, so it has good air purification and humidity control effects, and has a high rate of negative ions and far-infrared rays.

In addition, activated carbon is a material in which pores and surface area are increased by using chemicals such as steam or phosphoric acid in charcoal. It is a powdered activated carbon with a specific surface area of 500 ~ 1500㎡/g and a pore radius of 1 ~ 100nm, and a wide surface area And it has a porous structure of fine pores. In general, raw materials of carbon-based materials such as coal (lignite, bituminous coal, etc.), coconut shells, wood, petroleum pitch, petroleum coke, etc. are prepared through a carbonization attachment process, and the shape of the activated carbon used in the present invention is more powdered activated carbon than granular activated carbon. It is more advantageous in terms of its efficacy and manufacturing process to use.

In addition, the graphite powder is mixed at a rate of 100 g based on 1000 g of mud powder, thereby increasing the thermal properties and electromagnetic shielding effect due to excellent conductivity (heat, electricity), while mud - aggregation of charcoal components included in the porous powder composition In general, graphite is a mineral in which planar macromolecules (polycenes), in which a 6-membered ring of carbon atoms is infinitely connected in a plane, are layered and overlapped. Its property is a good conductor of heat and electricity, Due to the layered structure of polycenes, it is flexible and active, so it is easily cleaved, but because it is a macromolecule, it has low reactivity.

The coating agent containing the mud-porous powder composition prepared as described above has excellent air permeability, so it can semi-permanently maintain the function of adsorbing moisture, harmful substances and odors released, and also prevents the propagation of parasitic bacteria and fungi on cement walls. Since it has the advantage of not only effectively blocking but also removing volatile organic compounds (VOCs) floating in the air, the air between the interfaces is blocked, such as the coating film formed with the conventional coating agent, thereby reducing the effectiveness of functional coating agents. there is.

In addition, due to the microporous structure of the mud-porous powder composition lowering the thermal conductivity, the insulation properties of buildings and building interior materials to which the coating agent containing the same is applied can be improved to prevent dew condensation and save energy.

Finally, in the 6th process, 300 g of the mud-porous powder composition prepared in the 5th process was mixed with 1000 g of the illite-wood vinegar-silver nano adhesive prepared in the 4th process, followed by a ball mill for 3 hours. A process of preparing a coating agent for preventing sick house syndrome by grinding and kneading with a furnace. Through the grinding process, the mud-porous powder composition is formed into fine powders of several tens of μm or less to increase the specific surface area of each powder and improve the adhesion of the coating agent can make it

Since the sick building syndrome prevention coating agent prepared as described above is water-soluble, the viscosity is adjusted using chlorine-free purified water or distilled water and an eco-friendly water-soluble binder, and it is usually applied 1 to 3 times to obtain a uniform thickness of about 0.1 to 1 mm. It was confirmed that it can be applied and is very convenient in use.
