Today, modern people are living in indoor space for most of the day due to changes in lifestyle, working style, etc., and the demand for pleasant and healthy environmental condition of living, residence, work and work space is increasing. And various materials emitted from construction materials are becoming another problem that threatens the health of human beings.

However, due to the problem of depletion of fossil fuels, the necessity of energy management in the era of high oil prices due to the surge in oil prices has raised the indoor air quality to deteriorate due to the confidentiality of the building, the use of new insulation for reinforcing insulation, .

Recently, formaldehyde is the major source of indoor aldehydes such as building syndrome, sick house syndrome, and chemical hypersensitivity. As a source of such formaldehyde, a large amount is generated in insulation materials, fibers, janglong, sink, flooring, heating fuel combustion process, smoking, household goods, medicines and adhesives. When considering living indoors, the risk and impact are considered serious.

Also, carbon monoxide, which is one of representative indoor pollutants, adversely affects the human body even at a low concentration, and a high concentration of carbon monoxide is a harmful substance that is likely to die when exposed to the human body.

Techniques for treating such indoor pollutants include adsorbents and photocatalytic processes. However, the photocatalytic method has a problem of generating secondary pollutants due to UV irradiation.

Hereinafter, preferred embodiments of the present invention will be described in detail. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, the present invention will be described in detail with reference to the accompanying drawings. Throughout the specification, when an element is referred to as "including " an element, it means that it can include other elements, not excluding other elements, unless specifically stated otherwise.

The inventors of the present invention found that a bioceramic composition having antimicrobial and anion releasing functions in a specific ingredient composition and different adsorption and desorption capacities of formaldehyde, volatile organic compound (TVOC), carbon monoxide and ammonia exist, leading to the present invention . Hereinafter, the production process of the bioceramics composition according to the present invention will be described in detail.

The bioceramics composition according to the present invention is prepared by mixing and grinding illite, sericite, germanium and geysin (gunma feldspar) as main materials and selecting them. In the present invention, since all of the four main substances are crushed to a predetermined size, it is possible to exhibit antimicrobial and anion releasing function when passing a mixed gas containing odorous or harmful substances and to remove formaldehyde, volatile organic compounds, carbon monoxide and ammonia Can be implemented.

In the present invention, it has been found that it may be difficult to exhibit any one or more of antimicrobial activity, anion releasing function, and formaldehyde-removing ability, depending on the ratio of the main material. The removal efficiency of formaldehyde, the amount of volatile organic compounds, the amount of carbon monoxide, and the amount of ammonia can be reduced when the amount of cerium oxide is in the range of 10 to 80 wt%, 10 to 40 wt% of sericite, 1 to 10 wt% of germanium and 1 to 10 wt% It is confirmed that both can be implemented. The ingredient content of the main material may more preferably be in the range of 60 to 70% by weight of ilite, 20 to 30% by weight of sericite, 2 to 8% by weight of germanium and 2 to 8% by weight of ganoderma, May be in the range of 63 to 67% by weight of ilite, 23 to 27% by weight of sericite, 3 to 7% by weight of germanium and 3 to 7% by weight of lead oxide and most preferably 64 to 66% 24 to 26 wt%, germanium 4 to 6 wt%, and ganoderma 4 to 6 wt%.

In order to exhibit the above performance of the mixture of the main materials, it is necessary to be pulverized to a predetermined size. When pulverized particles having a size of 1,000 to 9,000 mesh are used, mixing and homogenization with a binder described later, Can be used. More preferably, the particle size is 2,000 to 8,000 mesh size, more preferably 3,000 to 8,000 mesh size, and most preferably 5,000 to 7,500 mesh size. The method of mixing and pulverizing the main material is not particularly limited, but when using an air jet mill grinder, it is possible to achieve a relatively uniform particle size.

The pulverized material of the main material has a function of directly discharging antimicrobial and anion releasing function and removing harmful substances such as formaldehyde. In actual use, the pulverized material of the main material is mixed with a binder at a certain ratio and coated on a subject such as a wall of a room Can be used. In order to prevent the generation of another unexpected harmful substance, the environmentally friendly liquid binder may be used. The content of the binder may be 1 to 100 parts by weight of the environmentally friendly liquid binder, 10 parts by weight, preferably 3 to 7 parts by weight, and most preferably 4 to 6 parts by weight.

The environmentally friendly liquid binder is not particularly limited as long as it is a water-soluble polymer composition that can be used for coating an object having a material such as wood, paper, plastic, or metal. For example, a water-soluble polyurethane- (Water) in an amount of 0.1 to 2% by weight, preferably 10 to 30% by weight, and an additive such as a dispersion, defoamer, and thickener may be used. The liquid binder has a solid content of 28 to 32% by weight, a viscosity (cps, 25 ± 1 ° C) of 500 or less, a pH of 7.0 to 9.0 and a hardness (100%, Modulus (kgf / It is particularly preferable that the binder is a medium-to-high-quality binder.

The present invention discloses a means for realizing the ability to oxidize formaldehyde at room temperature. That is, the present invention discloses a platinum / bioceramic catalyst having platinum supported on a bioceramics composition containing the main material. The platinum / bioceramic catalyst according to the present invention basically comprises a step of carrying a platinum precursor on a support of a bioceramic composition, followed by drying, firing and reduction.

The above carrying process can be carried out by impregnation as a method for carrying platinum, which is an active metal, on a supporting bioceramics composition. Specifically, the platinum precursor is quantitatively determined based on the weight of the carrier, dissolved in an aqueous solution, and the prepared bioceramic composition carrier and the aqueous solution in which the platinum precursor is dissolved are sufficiently mixed to prepare a slurry.

Examples of the precursor used for carrying the platinum include, but are not limited to, platinum chloride (PtCl ₄ ), tetraamine platinum nitrate (Pt (NH ₃ ) ₄ (NO ₃ ) ₂ ), platinum hydroxide (Pt ₂ ), hydroxyl platinum ((NH ₂ -CH ₂ -CH ₂ -OH) ₂ Pt (OH) ₆ ) and the like can be used.

The amount of the platinum precursor to be supported is preferably 0.01 to 1 part by weight, more preferably 0.02 to 0.5 part by weight, most preferably 0.05 to 0.1 part by weight based on 100 parts by weight of the above-described bioceramics composition carrier. If the content of the platinum precursor is less than 0.01 part by weight, the catalyst activity may not be satisfactory. If the amount of the platinum precursor is more than 1 part by weight, The smaller the metal content, the better.

Thereafter, the water content of the prepared slurry is removed by using a vacuum evaporator, and the residual moisture contained in the micropores in the slurry can be sufficiently dried by a dryer. For example, it can be dried by using a drier at a temperature of 90 to 115 ° C, preferably 100 to 105 ° C for at least 24 hours.

Thereafter, the dried sample is sintered to control the size and the degree of dispersion of the active metal through heat treatment. At this time, the firing temperature can be carried out at a temperature of 400 to 500 ° C. for 2 to 5 hours, preferably 3 to 4 hours, in consideration of agglomeration of the active metal at a high temperature. The firing process may be performed in various types of furnaces, such as a tube type, a convection type, and a grate type, and is not particularly limited.

Thereafter, the catalyst is subjected to a heat treatment in a reducing atmosphere for imparting optimum oxidizing ability at room temperature, and preferably at 500 to 700 ° C for 0.5 to 2 hours. If the heat treatment temperature is higher than 700 ° C, agglomeration of the active metal may occur. If the heat treatment temperature is less than 0.5 hour, the catalyst may not be sufficiently oxidized at room temperature. If the heat treatment temperature exceeds 2 hours, Coagulation phenomenon may occur.

The mixed gas containing formaldehyde is passed through the platinum / bioceramic catalyst manufactured by the above method, so that formaldehyde can be oxidized to carbon dioxide with high efficiency.

Meanwhile, the platinum / bioceramic catalyst according to the present invention can be processed in the form of a powder, a bulk of honeycomb, slate, pellet, etc., and can be coated on a surface of a metal or ceramic plate, fiber, filter or honeycomb structure .

Example  5: Adsorption and desorption characteristics of formaldehyde

In order to evaluate the adsorption and desorption characteristics of formaldehyde of the bioceramic composition according to the present invention, the bioceramic composition prepared according to Preparation Example 1 and titania (UV-100, hombikat co. ) Were subjected to TPO (Temperature Programmed Oxidation) analysis. The TPO analysis is performed by injecting the target substance into the catalyst layer and adsorbing the target substance to the catalyst. After that, argon is used to remove impurities and target substances on the surface of the catalyst in order to exclude experimental errors due to physical adsorption and vaporous substances. The adsorption and desorption characteristics of the catalyst are examined by measuring the temperature at which the target substance is removed from the catalyst surface by increasing the temperature while injecting oxygen into the catalyst layer. Experimental conditions and measurement methods are as follows.

[Experimental Conditions and Measurement Method]

Specifically, the 2920 Autochem (Micromeritics) was used, and the TPO analysis was performed using a TCD (Thermal Conductivity Detector) as a detector for the measurement. The order of analysis was 0.25 g of the catalyst pulverized to 100 μm or less. The catalyst was heated to 120 ° C. at a rate of 10 ° C./min by flowing argon (Ar) at a rate of 50 cc / min. Residual impurities were removed and the catalyst was activated. Thereafter, the temperature is lowered to room temperature of 30 ° C., and the target substance, 30 ppmv formaldehyde / nitrogen is continuously flowed and adsorbed on the surface of the catalyst. Then, argon is sparged at 30 ° C for 30 minutes to remove physical adsorption and gaseous formaldehyde. Thereafter, the reaction product which was desorbed by raising 5 vol.% Oxygen / argon to 800 ° C at a rate of 10 ° C / min was observed using TCD. The results are shown in FIG. 1a (bioceramic composition) and FIG. 1b Respectively.

Referring to FIG. 1, in the case of the bioceramic composition prepared according to Preparation Example 1, it was confirmed that the adsorbed formaldehyde was desorbed in the form of carbon dioxide by reacting with oxygen at a high temperature of 500 ° C or higher. Whereas titania is desorbed at 200 ° C. The higher the desorption temperature in the TPO analysis, the stronger the adsorption is. In addition, the target substance adsorbed at room temperature is concentrated at a high concentration over time, and this substance can be desorbed at a high concentration as the temperature rises.

Example  6: Carbon monoxide adsorption and desorption characteristics

In order to evaluate the carbon monoxide adsorption and desorption characteristics of the bioceramic composition according to the present invention, the bioceramic composition prepared according to Preparation Example 1 and titania (UV-100, hombikat co.), Which is a typical photocatalyst material, TPO (Temperature Programmed Oxidation) analysis was carried out on the surface of the substrate and the results are shown in FIG. 2A (bioceramic composition) and FIG. 2B (titania), respectively. Experimental conditions and measurement methods were performed in the same manner as in Example 5, except that the target substance was carbon monoxide and the substance desorbed using Quadrupole Mass (200M) was monitored.

2, the bioceramic composition prepared according to Production Example 1 desorbs most of the carbon dioxide (CO ₂ ) form at a temperature of 600 ° C. or higher. In the case of titania, the carbon dioxide (CO ₂ ) As shown in FIG.

Example  7: Ammonia adsorption and desorption characteristics

In order to evaluate the ammonia adsorption and desorption characteristics of the bioceramic composition according to the present invention, the bioceramic composition prepared according to Preparation Example 1 and titania (UV-100, hombikat co.), Which is a typical photocatalyst, TPO (Temperature Programmed Oxidation) analysis was carried out on the surface of the sample. The results are shown in Fig. 3A (bioceramics composition) and Fig. 3B (titania), respectively. Experimental conditions and measurement were carried out in the same manner as in Example 6, except that the target substance was ammonia.

Referring to FIG. 3, the bioceramic composition prepared according to Preparation Example 1 is desorbed in the form of nitrogen dioxide (NO ₂ ) at a temperature of 600 ° C. or higher, but in the case of titania, it is desorbed from a low temperature region of 50 ° C. to a high temperature region of 500 ° C. It was confirmed that it was desorbed in the form of nitrogen (NO) and nitrogen dioxide (NO ₂ ). That is, in the case of the bioceramics composition prepared according to Preparation Example 1, it means that a highly concentrated target substance due to adsorption is adsorbed to a high temperature region of 600 ° C without desorbing at a low temperature. On the other hand, in the case of titania, high concentrations of nitrogen monoxide (NO) and nitrogen dioxide (NO ₂ ) due to adsorption are desorbed at a high temperature in a low temperature region of 50 ° C, which means that toxic substances can be generated at a high temperature in a low temperature region.

Example  8: formaldehyde room temperature Oxidative ability  evaluation

To evaluate the oxidizing ability of platinum / bioceramic catalyst according to the present invention at room temperature, formaldehyde oxidizing ability at room temperature was evaluated by the following experimental conditions and measurement methods for the platinum / bioceramic catalyst prepared according to Production Examples 2 to 4, Are shown in Table 6 below.

[Experimental Conditions]

The formaldehyde used in the experiment was placed in a double jacket maintained at 20 ° C as paraformaldehyde ((CH ₂ O) n: Aldrich Chemical Co.) and vaporized Formaldehyde was introduced into the reactor using a carrier gas. For reference, the space velocity is an index representing quantitatively the amount of the target gas that can be treated by the catalyst, and is expressed as a ratio of the amount of catalyst (volume) to the total gas flow rate (volume).

[How to measure]

When formaldehyde is oxidized, carbon dioxide (CO ₂ ) is produced by the following reaction formula 1, and a non-dispersive infrared gas analyzer (ZKJ-2, Fuji Electric Co.) was used to measure the amount of generated carbon dioxide. In this case, a detector tube (91, Gas Tec. Co.) was used at the downstream of the fixed bed reactor to measure the presence of unreacted formaldehyde.

[Reaction Scheme 1]

HCHO + O _{2 -} > CO ₂ + H ₂ O

Referring to Table 6, it was confirmed that the catalyst having a very small amount of active metal (platinum) content of 0.01 part by weight did not exhibit formaldehyde room temperature oxidizing ability but the catalyst having a platinum content of 0.05 parts by weight had a normal oxidizing ability of formaldehyde at room temperature of 65% , And a catalyst having a platinum content of 0.1 part by weight was found to have excellent oxidizing ability at room temperature for completely oxidizing formaldehyde with carbon dioxide under a condition of a space velocity of 15,000 hr ^-1 .
