Description

Technical Field [0001] The present invention relates to a sericite deodorant and a method for manufacturing the sericite deodorant,

The present invention relates to a perennial ceramics deodorant prepared by mixing, molding and sintering a mixture of a sericite powder and a binder which is easily dissolved by a deodorizing object and a method for producing the same.

As the living environment and the level of consciousness are improved, there is a growing interest in eliminating unpleasant odors and odors in everyday life. In addition to odors such as sewage, housing manure, sewage disposal plant, toilet, garbage, refrigerator, Tobacco odor, sweat odor, pet odor problems are also raised.

Typically, the offensive odor is an acidic smell such as hydrogen sulfide, methyl sulfide, methyl disulfide, methyl mercaptan and the like; Basic odor such as ammonia, trimetalamine, scallol and the like; Acetaldehyde, styrene, and the like, and there is a limit in blocking the generation of odor due to a wide variety of odor sources. Therefore, researches have been focused on deodorization techniques for removing odors generated.

The conventional biofilter deodorization method is a biological treatment method in which microorganisms are fixed on a natural or artificial carrier and is suitably used for treatment of a gas having a low concentration and a high air volume and has a low operation cost, However, there is a disadvantage in that the installation area of the apparatus is large and it is not suitable for high temperature and high concentration gas treatment.

Soil deodorization method is a method to remove odor components by using microorganisms in the soil layer. It is simple in equipment, low in initial investment and operating ratio, but has a disadvantage in that it is difficult to select operating conditions and is not suitable for treatment of high temperature and high concentration exhaust gas .

The adsorption deodorization method is a method of treating by the physical adsorption ability of an adsorbent such as activated carbon, and is suitable for removing low-concentration volatile organic compounds (VOCs) and has a simple equipment. However, the second pollution occurs when the adsorbent is discarded after use And it is weak in tar, moisture, dust, etc., and there is a fear that a fire may occur when treating VOCs.

The catalytic combustion deodorization method is a method for oxidizing malodorous components at a temperature of 350 to 450 ° C. by using a catalyst, which is suitable for treating gas at high temperature and high concentration. However, it is difficult to treat catalyst poisonous substances such as sulfur components There is a drawback.

The direct combustion deodorization method is a method of thermally oxidizing and decomposing odorous components at a high temperature of 850 ° C or more. It is advantageous for high concentration gas treatment and can treat various components. However, since the initial investment and operation ratio are high and NOx There is a possibility.

The chemical solution washing and deodorizing method is a method of decomposing odorous components by using an oxidizing agent, which is less affected by the temperature of the treating gas and is suitable for treatment of a large amount of gas at a low concentration and can treat dust simultaneously. However, There is a disadvantage that the pollutants can be discharged and the equipment is corroded.

A deodorant is a medicament which removes or alleviates an unpleasant odor by adsorption, absorption, oxidation, addition, decomposition, neutralization, concealment or the like. As the deodorant of the adsorption type, there is no adsorbent such as activated carbon, silica gel, There are chemically adsorbed and deodorized adsorbents which adsorb physically adsorbed deodorant, potassium permanganate aqueous solution, bleaching aqueous solution, acid, base and oxidant such as formalin, and adsorbent system. The adsorption system includes exchange type adsorption type deodorization device and regeneration type adsorption type deodorization device.

In recent years, with increasing preference for natural products, interest in natural deodorants made from natural materials has been increasing more than chemical deodorizers made with chemical substances. Accordingly, the deodorization effect Research and development are being actively pursued.

One of these natural materials, sericite, is a group of hydrated aluminum silicate minerals with a layered structure and is excellent in functions such as far infrared ray emissivity, deodorization rate, antibacterial and antifungal properties, anion release, antifouling and air purification.

Sericite is substantially silicon dioxide (SiO ₂₎ 60%, aluminum oxide _{(Al 2 O 3) 10%} , potassium oxide (K ₂ O) 9.0%, Magnesium (MgO) 2.9% oxide, ferric oxide (Fe ₂ O ₃₎ 1.8 %, 0.1% of calcium oxide (CaO), 0.1% of sodium oxide (Na ₂ O), and other water molecules. The oxygen atoms supporting the potassium atom as its apex and the aluminum, silicon and other metals and hydrogen , Which are extremely stable and have a structure in which oxygen and potassium atoms are irregularly substituted in the basic crystal structure.

The sericite has high plasticity, drying strength and green strength and is used in various fields such as paints, electric insulators, lubricants and cosmetics. It is not widely used as a material for deodorant.

This is because the pore capacity of the sericite does not reach the activated carbon and the adsorption capacity is relatively low. Also, since the constituents of the sericite have a stable crystal structure, there is a limit to the decomposition reaction of the malodorous organic component by the metal component of the sericite.

As a method for producing a deodorant using sericite, Korean Patent Laid-Open Publication No. 2004-0009759 discloses a method for producing a deodorant by crushing and drying ceriseite ore, adding a conventional coagulant used for general building materials, molding and drying .

The present invention provides a deodorant which is excellent in deodorization effect and can be reused in water because it can be reused in water. However, as the deodorization progresses, the adsorption ability gradually decreases as the pores of the sericite are filled with the progress of deodorization. There is a problem that the coagulant clogs the pores of the sericite to reduce the adsorption effect of the deodorant.

Korean Patent Publication No. 1102429 discloses an invention in which sericite and purified water are mixed and stirred, and then antibacterial metal ions and an antioxidant are added to give sericite an antibacterial and deodorizing function.

The present invention provides an effect of prolonging the antibacterial life of sericite by binding a metal component to a sericite to have continuous antibacterial and deodorizing ability and using an antioxidant to inhibit denaturation of metal ions, but sericite has a stable crystal structure The amount of metal components bound to sericite is limited and the antimicrobial activity is not expected. It is difficult to expect the adsorption effect of the odorant component of the sericite formed by the liquid phase, and there is a restriction in application to the product as a deodorant.

Disclosure of the Invention Problem to be solved by the conventional deodorant having a sericite as described above is to provide a monodisperse deodorant and a monodisperse deodorant which can prevent the deodorizing ability from being deteriorated even if the deodorization continues while maximizing the adsorption capacity of the sericite and the decomposition ability of the malodor component. And a method for manufacturing the same.

In order to solve the above-described problems, the present invention provides a method for producing a fiber-reinforced composite material comprising 90.0 to 99.9% by weight of a sericite powder and 0.1 to 100% by weight of at least one binder selected from the group consisting of carboxymethylcellulose, cellulose, bentonite, starch, gelatin, 10.0% by weight of montmorillon deodorant.

Further, the present invention relates to a method for producing a warp-knitted fabric by pulverizing a sericite to produce a sericite powder; The mixture of 90 to 99.9% by weight of the sericite powder is mixed with 0.1 to 10.0% by weight of at least one binder selected from the group consisting of carboxymethylcellulose, cellulose, bentonite, starch, gelatin, clay, clay and sodium silicate ; Adding water to the mixture and molding the mixture to produce a molded product; And drying and then sintering the molded article.

At this time, it is preferable that the rhizome powder has a diameter of 10 to 100 μm, a sintering temperature of 300 ° C. or less, and a sintering temperature of 3 to 7 ° C./min.

It is further preferable that the metal hydroxide is added to the water, and the metal is at least one selected from the group consisting of silver, copper, trivalent chromium, cobalt and zinc.

In addition to the moldability that can not be easily broken even when a force is applied, the antifoaming agent according to the present invention can easily dissolve the deodorant on the surface by the object to be deodorized and remove the new antifoam powder, So that the deodorization efficiency of the sericite deodorant is continuously maintained at a high level.

In addition, since it is made of a natural material, sericite, it is harmless to the human body and does not adversely affect the natural environment during use, and secondary pollution does not occur even at the time of disposal.

In the method for manufacturing a perennial ceramics deodorant of the present invention, a sericite deodorant is prepared by pulverizing a sericite, adding a binder thereto, forming a solid having a predetermined volume, and then calcining.

In order to maximize the total surface area of the sericite powder, it is preferable to pulverize and finely pulverize the sericite to a size of 10 to 100 mu m in diameter.

Next, the binder is mixed with the sericite powder, and water is added thereto.

The binder is made of a material which can be slowly dissolved depending on the use environment of the object to be deodorized and the deodorant while shaping the sericite powder into a predetermined shape.

As such a binder material, carboxymethyl cellulose (CMC), cellulose, bentonite, starch, gelatin, white clay, clay (clay) clay, And sodium silicate may be used alone or in combination.

The above-mentioned carboxymethyl cellulose is a white solid prepared by reacting an alkali cellulose with a chloroacetate, and is a water-soluble cellulose having not more than 0.8 sodium glycolate · ether groups per cellulose molecule and becoming a sticky liquid when dissolved in water.

Cellulose, also known as cellulose, is the most abundant organic compound in nature and is the basic structure of plant cell walls. It is the main constituent of the cell membrane and woody part of the plant. It is insoluble in water but hydrolyzed in acid and dissolved in copper ammonia solution. Alkali- To dissolve.

Bentonite is a gray, light brown, pale green and white clay mainly containing montmorillonite, which is a monoclinic mineral. It absorbs water between thin plate crystal layers in water and disperses in water to form a colloidal dispersion exhibiting a high structural viscosity. When the concentration is increased, it forms a sticky gel on the agar.

In addition to such thickening action, there are actions such as suspension stabilization of other substances such as solid particles mixed together, protective colloid action and imparting paste reversibility with high concentration of solid particles, and they are mixed with water and gelled to prevent agglomeration and coalescence of emulsion particles And is used to improve foam stability and multi-stability.

Starch is a polysaccharide produced by the condensation reaction of a large number of glucose. It is a mixture of 20-25% of amylose and 75-80% of amylose. It does not dissolve in water but poured hot water or poured water to heat The starch particles swell and become a viscous liquid, that is, a paste.

Gelatin is a kind of inducible protein obtained by treating collagen, which is a natural protein, with hot water. It is swollen in cold water only, but becomes soluble in hot water and becomes a sol. At a concentration of 2 to 3% or more, Such coagulability can be used as a binder material for shaping the sericite powder into a certain shape.

White clay is a white clay used as a raw material of white ceramics. It is divided into a first clay and a second clay. The first clay has a poor point of view. The second clay has a good point. Since it is a collection of fine particles, But it shows rigidity when dried.

Clay is weathered and decomposed clay of granite rock. It is used as a raw material for ceramics. It is mainly composed of kaolin, has low plasticity and strength, and has blue and white neck, white neck, black neck and neck.

Sodium silicate is a sodium salt of silicic acid. It is soluble in water and can be used in aqueous solution or solid state. It has gelling property and is used for quick-setting of cement, adhesive, soil hardening agent, and settlement of molding sand.

The mixing amount of the binder varies depending on the use of the deodorant, but it is appropriate that the amount of the sericite powder: binder is in the range of 90.0 to 99.9: 0.1 to 10.0 wt%, the amount of water is sufficient to knead the warp- Hot water may be used to dissolve in water.

In order to improve the antimicrobial and deodorizing function of the deodorant, it is preferable that the deodorant contains a large amount of metal components having excellent antibacterial and organic substance decomposition functions. In the sericite, a metal element such as aluminum, potassium, magnesium, iron, calcium, But their effect is insignificant because of their low antibacterial and organic decomposition ability.

The antimicrobial activity of the metal ions reported in the academia is approximately silver (Ag)> mercury (Hg)> copper (Cu)> cadmium (Cd)> chromium (Cr)> lead (Pb)> cobalt (Co) It is preferable to replace the metal elements contained in the sericite with the metal elements having excellent antimicrobial activity in the order of zinc (Zn)> iron (Fe)> manganese (Mn)> molybdenum (Mo)> tin (Sn).

For this purpose, the metal hydroxide is preferably added to the water, and the metal is more preferably a metal element having excellent antibacterial and organic substance decomposition promoting function. In view of economical efficiency, Most preferred are chromium, cobalt and zinc.

When metal hydroxide dissolves in water, it dissociates into hydroxide ion and metal ion, and dissolving heat is generated. Such dissolution heat increases the water temperature, and the higher the water temperature, the better the dissolution of the metal element contained in the sericite.

The ionization tendency reactivity is high in the order of potassium> calcium> sodium> magnesium> aluminum> zinc> iron> nickel> tin> lead> copper> mercury> silver so that water-dissociated hydroxyl ions penetrate the stratified- It accelerates dissolution of metal elements by reacting with metallic elements such as potassium, calcium, sodium, magnesium and aluminum having a high tendency to ionization, and has a function of promoting dissolution of antimicrobial and organic substances dissociated from metal hydroxides Metal ions such as silver, copper, trivalent chromium, cobalt, and zinc are combined with sericite.

In addition, metal ions such as potassium, calcium, sodium, magnesium and aluminum eluted from the sericite are fixed on the surface of the sericite powder during the drying and sintering processes. Therefore, the metal ions bonded or fixed to the sericite may have a function of deodorizing the sericite deodorant It is not easily separated from the deodorant, so that the antibacterial and organic matter decomposition ability can be continuously exhibited.

Next, a mixture of the above-mentioned sericite powder, the binder and water is formed into a certain shape.

The shape to be molded can be freely adjusted in size and shape depending on the use of the deodorant. It can be shaped into a block or granular shape depending on the replacement cycle of the deodorant, the environment of use, the speed of dissolution of the binder depending on the object to be deodorized, .

For example, when used to remove odors from a toilet urinal, it can be used individually as spheres, ellipses, and cylinders, and when used as a deodorizer of a refrigerator, it can be molded into granules and packed with a plurality of granules .

Next, the molded article is dried to maintain the molded shape, and then sintered to impart strength, thereby completing the production of the antifouling agent according to the present invention.

The drying may be natural drying or artificial drying, but it is preferable to naturally dry it because it is subjected to a heat treatment in a sintering process.

It is preferable that the sintering temperature is not higher than 300 ° C, more preferably 200 to 300 ° C, and the heating rate during sintering is preferably 3 to 7 ° C / min. The sintering temperature and the heating rate are preferably such that the binder has porosity So that the adsorption capacity of the sericite does not deteriorate.

The perennial antifouling agent thus prepared contains 90.0 to 99.9% by weight of the sericite powder and 0.1 to 10.0% by weight of at least one binder selected from the group consisting of carboxymethylcellulose, cellulose, bentonite, starch, gelatin, clay, clay and sodium silicate %.

During the deodorization of the malodor component, which is the object of deodorization, the object of deodorization first comes into contact with the surface of the deodorant, the binder of the surface of the deodorant is dissolved by the object to be deodorized and gradually removed from the surface of the deodorant, The new sericite powder under the surface of the deodorant is exposed on the surface and adsorbs the malodor component so that the initial adsorption ability of the deodorant can be maintained continuously.

For example, when used to remove odors from a toilet urinal, a sericite deodorant molded into a spherical shape using water-soluble carboxymethylcellulose, cellulose dissolved in a copper-ammonia solution, starch dissolved in hot water, and gelatin as a binder, The binder on the surface is gradually dissolved due to the ammonia component of the urine and the urine temperature due to the body temperature and thus the sericite on the surface adsorbing the malodor component is removed, The odor component is adsorbed again.

Also, when used to remove the odor of a refrigerator, the bronze, the clay, and the clay are formed into granules, and a plurality of the granules are packed with the cloth, and the sericite deodorant installed on the refrigerator door is first subjected to volatilization As the use of the odor component is continued, the binding force of the binder on the surface is weakened by the moisture of the refrigerator and the sericite on the surface adsorbing the odor component is removed by being released from the surface by opening and closing of the refrigerator door. The odor component is adsorbed.

Hereinafter, the present invention will be described in more detail with reference to the following examples, comparative examples and test examples.

It is to be understood, however, that the invention is not to be construed as being limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the invention to those skilled in the art. Will be apparent to those skilled in the art to which the present invention pertains.

The results of Tables 1 and 2 show that when the binder is not mixed with the binder, sintering at 800 ° C or less for 30 minutes results in poor moldability and sintering at 920 ° C or more for 30 minutes results in poor dissolution.

When the binder is contained, the formability and the solubility are determined according to the sintering temperature and the sintering time in the range of 0.1 to 10.0 wt%, and there is no difference in the type and content of the binder. However, The sintering time exceeded 300 ° C, and the solubility tends to decrease as the sintering time increases or the binder content increases.

&Lt; Test Example 2 > Microstructure Observation of Rhizome Rhizoma Deodorant

Microstructures of the sericite powder and the antifouling agent of the present invention were observed using a Field Emission Scanning Electron Microscope (FE-SEM).

Fig. 1 is a graph showing the results of a comparison between the control (the sericite powder without mixing the binder) of Test Example 1, the sericidal deodorant prepared in the Example, the sericite powder of 99.5% by weight and the bentonite of 0.5% 3 is an FE-SEM photograph of a deodorant containing 99.0% by weight of a sericite powder and 1.0% by weight of gelatin and sintered at 150 ° C for 60 minutes after natural drying.

As shown in FIGS. 1 and 2, it can be seen that the sericite and deodorant have a fine layered structure, and in FIG. 3, the gelatin covers the layer of the sericite.

<Test Example 3> Deodorizing efficiency analysis

The deodorization efficiency of ammonia, which is a main component of toilet and refrigerator odor, was measured using the monocotyledonous deodorant prepared in the above example, and the results are shown in FIG. 4 and FIG.

In addition, the deodorization efficiency of methyl mercaptan, which is the main component of the refrigerator odor, was measured and the results are shown in FIGS. 6 to 8.

(Fig. 4) containing 99.5% by weight of sericite powder and 0.5% by weight of bentonite and sintered at 200 캜 for 30 minutes after natural drying, 99.0% by weight of sericite powder and 1.0% by weight of gelatin (Fig. 5) which was sintered at 150 캜 for 60 minutes after natural drying and contained deodorant (Fig. 6) containing 99.5% by weight of sericite powder and 0.5% by weight of bentonite and sintered at 200 캜 for 30 minutes after natural drying, (Fig. 7), 90.0% by weight of sericite powder, and 10.0% by weight of soluble starch, which were sintered at 100 캜 for 60 minutes after natural drying and 10.0% by weight of carboxymethyl cellulose, The deodorant sintered for 30 minutes was packed in a nonwoven fabric (FIG. 8).

The measurement was conducted by KS I 2218: 2008 test method, which is a detector tube gas measuring method,

As shown in FIGS. 4 and 5, the ammonia concentration decreased by 5% at 120 minutes when no deodorant was added (BLANK). However, the sericidal deodorizer of the present invention exhibited 96% ammonia deodorization efficiency after 30 minutes.

In FIGS. 6 to 8, the methyl mercaptan concentration decreased by about 6% at 30 minutes after the BLANK in the absence of the deodorant, but the trochoid deodorizer of the present invention showed a methylmercaptan deodorization efficiency of 80% Able to know.

As can be seen from the above, the monocotyledonous deodorant according to the present invention is not easily broken even when applied with a force. In addition, since the deodorant on the surface is easily dissolved and removed by the object to be deodorized, a new sericite powder under the surface of the deodorant is exposed on the surface, And thus the deodorization efficiency of the antifoam deodorant is maintained to be high continuously.

In addition, since it is made of a natural material, sericite, it is harmless to the human body and does not adversely affect the natural environment during use, and secondary pollution does not occur even at the time of disposal.
