Description

A method for producing a naturally-occurring antibacterial deodorant adsorbent composition {A MANUFACTURING METHOD OF ADSORPTIVE COMPOSITION HAVING ANTIMICROBIAL AND DEODORANT FUNCTION}

The present invention relates to a method for producing an antibacterial and deodorant adsorbent composition harmless to the human body, which can adsorb and block harmful substances and have an antibacterial effect. The antimicrobial deodorant adsorbent composition prepared according to the present invention can prevent the emission of various organic compounds used in the preparation of interior materials by coating on the surface of the building interior materials and at the same time have an antibacterial function to suppress harmful bacteria, antibacterial ink for Organic solvents can be used as natural binders. In addition, the antimicrobial deodorant adsorbent composition prepared by the present invention emits a fresh natural flavor.

In general, various interior materials including building interior materials are products manufactured by adhering a plurality of synthetic resin boards or wooden boards with a chemical wallpaper adhesive to form a multi-layered structure, coloring the surface of the multi-layered structure, or bonding a patterned sheet paper. Various interior materials produced in this way are widely used because of their relatively light weight and low cost.

However, in order to join a synthetic resin interior material or wood board in a multi-layered structure, a synthetic resin adhesive should be used. Such a synthetic resin adhesive has advantages in that various physical properties related to adhesion such as adhesive strength and adhesive durability are excellent. Compounds or volatile substances not only adversely affect the health of people living in the facility, but also cause mold to develop in the interior material, which may cause harmful bacteria to cause diseases in the human body.

Therefore, in order to prevent or suppress the emission of various organic compounds or volatile substances that adversely affect people's health, various compounds have been developed to coat the interior materials, but the developed interior coating materials also emit substances harmful to the human body. Therefore, there is a problem in that it is not effective even if applied to the interior material, and also contains a chemical mold inhibitor in addition to the compound for coating the interior material to suppress the occurrence of mold.

For example, a new house syndrome blocker manufactured using conifer extract and granite has been disclosed, but the blocker is expensive, has a problem in durability, and over time, the effect of inhibiting the divergence of organic compounds or volatile substances is reduced. There is this. In addition, a technique for covering furniture sheet using a charcoal-containing compressed sheet paper has been disclosed, but such a compressed sheet also has a problem that it is difficult to actually apply to the interior material because it emits a substance harmful to the human body itself. In addition, the composition for interior and exterior materials using the mica and elvan have been disclosed, but such interior and exterior materials have a problem in that the cost is high and the use is limited.

In addition, in the field of antimicrobial ink, conventional antimicrobial inks are prepared including polyvinyl acetal resin, colored dyes, antibacterial agents and solvents as organic binders. The anti-microbial ink uses water and alcohol as solvents, but there is a risk that volatile organic compounds are released from the antimicrobial ink due to the organic solvent used to synthesize the polyvinyl acetal resin as a binder, thereby damaging the user's health.

Accordingly, an object of the present invention is to prevent the emission of volatile organic compounds and at the same time can act as an antimicrobial to harmful bacteria, a method for producing an antibacterial deodorant adsorbent composition harmless to the human body that can simultaneously meet the functions of the ink binder and antimicrobial agent. To provide.

In order to achieve the above object, the present invention mixed 10-15 parts by weight of vegetable strawberry extract, 10-15 parts by weight of herb extract, licorice extract 10-15 parts by weight, 25-30 parts by weight of mulberry leaf fermentation extract and 100 parts by weight of electrolytic reduced water Forming a first composition by stirring (S10), forming a liquid silver nano inorganic antimicrobial agent (S20), by mixing 10 to 15 parts by weight of the silver nano inorganic antimicrobial agent in the first composition with respect to the electrolytic reduced water contained in the composition 2 to form a composition (S30), the zeolite and ethanol in the second composition is mixed with 15-20 parts by weight and 3-5 parts by weight with respect to the electrolytic reduced water contained in the composition, mixed for a predetermined time and stirred and nano-crushed Forming a third composition (S40), leaving the third composition for a period of time, the solid / liquid separation and filtration step (S50), the filtered filtrate recovered at 70 to 75 ℃ 90 Liver stirred to provide a fourth step of forming a composition (S60), and methods of making the antimicrobial absorbent deodorizing compositions comprising a step (S70) of the fourth composition for 24 hours aging at room temperature for fermentation.

Antimicrobial deodorant adsorbent composition according to the present invention is composed using a certain amount of zeolite and silver nano inorganic antibacterial agent.

Zeolites are electrically neutralized with cation suspended particles in water to cause precipitation, thereby having excellent water purification, high moisturizing effect and activity. In addition, as a substance that emits 90% or more of far-infrared rays that promote human blood circulation and activate cell activity, it has a deodorizing and antibacterial function of adsorbing various harmful substances such as benzene, toluene, xylene, and humidity control.

Inorganic silver antibacterial agent uses the silver-based antibacterial agent composed mainly of citric acid _{(C 6 H 5 O 7 Ag} 3 +). It is harmless to the human body, non-toxic, persistent and has a strong antibacterial property. The silver nano inorganic antimicrobial agent in the present invention exhibits a very good antimicrobial activity with the mulberry leaf extract which is another component of the composition, thus eliminating the need for a chemical antimicrobial agent. Mulberry leaf extract containing allicin is the most excellent antifungal effect among natural foods.

The antimicrobial deodorant adsorbent composition prepared according to the present invention is harmless to the human body because it does not contain an organic solvent, and releases a large amount of far infrared rays and anions that are beneficial to the human body, such as Candida by the antimicrobial action of the silver nano antibacterial agent included in the composition. It can protect the human body from harmful bacteria.

When the composition prepared according to the present invention is applied to a building interior material, various organic compounds or volatile substances used in the preparation of the interior material are prevented from being emitted, and the antimicrobial action of the silver nano antibacterial agent included in the composition prevents harmful bacteria. The human body is protected. In addition, the composition prepared according to the present invention can be used as a non-organic solvent natural binder for antibacterial ink. In addition, the composition prepared by the present invention emits a fresh natural flavor.

Figure 1 shows the procedure of the antimicrobial deodorant adsorbent composition manufacturing method according to an embodiment of the present invention.

The configuration of the present invention will be described in detail with reference to the drawings.

First, strawberry extract, herbal extract, licorice extract, mulberry leaf fermentation extract, and electrolytic reduced water are mixed and stirred to form a first composition (step S10).

Specifically, 10-15 parts by weight of vegetable strawberry extract, 10-15 parts by weight of herbal extract, 10-15 parts by weight of licorice extract, 25-30 parts by weight of mulberry leaf fermentation extract, and 100 parts by weight of electrolytic reduced water by mixing and stirring the vegetable liquid composition To obtain. Preferably, the herbal extract is used rosemary extract. Preferably, the mulberry leaf fermentation extract is used that fermented at a high temperature of 70 ℃ or more.

If the strawberry extract, herb extract and licorice extract in the present invention is less than 10 parts by weight of the natural flavor divergence effect is lowered, if more than 15 parts by weight does not emit more natural flavor corresponding to the excess amount. If the mulberry leaf fermentation extract is less than 25 parts by weight, the fungal inhibitory effect of the mulberry leaf fermentation extract is lowered, if it exceeds 30 parts by weight does not increase the mold inhibitory effect corresponding to the excess amount.

In the present invention, the raw water (tap water) is passed through the electrolytic reduced water device to remove + ions, and then the electrolytic reduced water produced by the process of obtaining-ionized water is used. Electrolytic reduced water is pure-ionized water made by filtration of raw water by physical and chemical methods, and it is a process of removing various minerals. Electrolytic reduced water is mainly used for cleaning of glassware and solvents in laboratories, etc., and facilitates mixing of each component constituting the composition with natural mineral components.

Next, a liquid silver nano inorganic antimicrobial agent is formed (S20).

Specifically, the silver nano inorganic antimicrobial agent used in the present invention is a silver antimicrobial agent whose main component is silver citrate. Silver nano inorganic antimicrobial agent is comprised by mixing 20-30 weight part of silver citrate with respect to 100 weight part of mixed solvents of water and ethanol. As a mixed solvent for dissolving silver citrate, a mixed solvent having a ratio of water and ethanol of 2: 3 is preferable in view of solubility. The water of the mixed solvent is preferably alkaline ionized water and ethanol is vegetable ethanol. If the content of silver citrate dissolved in the mixed solvent is less than 20 parts by weight, the antimicrobial activity of the antimicrobial agent is not sufficient, and if it exceeds 30 parts by weight, silver citrate is not completely dissolved in the mixed solvent.

In addition, a surfactant may be added to further enhance the antimicrobial properties of the silver nano inorganic antimicrobial agent. As the surfactant, ABDM (alkylbenzyldimethyl ammonium chloride) showing strong bactericidal power may be used. Applicants have found that silver citrate and ABDM are electrically interacted to express stronger antimicrobial activity. Therefore, better results can be obtained by adding the ABDM surfactant component to the silver nano inorganic antimicrobial agent.

Next, a silver nano inorganic antimicrobial solution is mixed with the first composition in an amount of 10 to 15 parts by weight based on the electrolyzed water contained in the composition to form a second composition (S30).

If the content of the silver nano inorganic antimicrobial agent is less than 10 parts by weight, sufficient antimicrobial activity is not provided, and if it exceeds 15 parts by weight, the relative content of other components is lowered.

Next, zeolite and ethanol are mixed and stirred in the second composition to form a mixed composition, and the formed composition is stirred at high speed to nano-pulverize to form a third composition in which a neutralized aggregation phenomenon occurs (step S40).

Specifically, zeolite and ethanol are mixed with the first composition in an amount of 15-20 parts by weight and 3-5 parts by weight based on the electrolyzed water contained in the composition, respectively, to form a mixed composition. The mixed composition is poured into a high-speed reactor and stirred for a predetermined time to form a paste-like composition. The above-described composition was stirred at a high speed of 7500 rpm for 15 to 30 minutes to nano-crush the zeolite and other granular components contained in the mixture, but stirred until the zeolite became 8,000 to 10,000 mesh, and nano-crushed at the same time. The second composition is obtained by causing neutralization of the powder and silver nano antibacterial agent and the vegetable component.

If the stirring time of the second composition is less than 15 minutes, the zeolite and other granular components are not finely ground to the above-mentioned values, and if the stirring time exceeds 30 minutes, the zeolite and the granular components are no longer finely ground. In addition, if the zeolite and other components included in the second composition are less than 8,000 mesh, the composition does not sufficiently neutralize, and if it exceeds 10,000 mesh, the quality of the composition is no longer improved compared to the increase in the grinding cost. If the zeolite is less than 15 parts by weight, the adsorption and deodorization function of the zeolite is lowered, and if it exceeds 20 parts by weight, the adsorption and deodorization function does not increase corresponding to the excess amount. Ethanol is added to adjust the concentration of the composition. When the amount of ethanol is less than 3 parts by weight, the viscosity of the composition may become high and may not be properly agitated. If the amount of ethanol exceeds 5 parts by weight, excessive neutralization may occur. Ethanol uses vegetable ethanol, preferably licorice fermented ethanol.

As described above, the third composition in which the neutralization phenomenon occurs in step S40 is left for about 30 minutes to separate solids / liquids into a precipitate which is a fine powder of zeolite and granular components, and a supernatant in which zeolite and silver antimicrobial components and vegetable components are dissolved. The supernatant is collected (step S50).

If the time for leaving the third composition is less than 30 minutes, the zeolite and other granular components are not completely precipitated, the adsorbed zeolite micropores are not sufficiently adsorbed, and if the time to leave is longer than 30 minutes, the zeolite and other granular components are No more precipitation

The solid / liquid separated composition as described above is filtered by a known technique to recover a filtrate (supernatant).

Next, the recovered filtrate is stirred for 90 minutes at 70 to 75 ℃ to form a fourth composition (step S60).

If the reaction temperature of the composition is less than 70 ℃ the purity of the composition is lowered, if the reaction temperature exceeds 75 ℃ ethanol contained in the composition is decomposed. In addition, when the reaction time of the composition is less than 90 minutes, the saturation of the composition is increased to form a hydrophobic composition, and when the reaction time exceeds 90 minutes, the composition no longer reacts.

Finally, the fourth composition is aged at room temperature for 24 hours (step S70).

The antimicrobial deodorant adsorbent composition prepared by the above step does not contain an organic solvent harmful to the human body. In addition, it is safe because it is manufactured using vegetable ingredients, and can be protected from harmful bacteria due to the addition of non-toxic antibacterial agents. When the composition prepared by the present invention is used in building interior materials, it exhibits the adsorption power to the harmful substances and strong antimicrobial power at the same time, can be used as a non-organic solvent natural binder for antibacterial ink.
