Hereinafter, the present invention will be described in detail.

The antibacterial, deodorizing, and average emissivities of the single component ceramics constituting the composite ceramics having far-infrared radiation properties and having antibacterial and deodorizing properties used in the present invention were measured. 1, the measured values shown in Table 2 were obtained.

[0008]

[Table 1]

[0009]

[Table 2]

From the results shown in Table 1, magnesia has an antibacterial rate of nearly 100% against Escherichia coli and staphylococci, but has little deodorizing properties against odor sources such as ammonia and hydrogen sulfide. Zinc has a deodorization rate of 100% with respect to hydrogen sulfide, but has little deodorization and little antibacterial property with respect to ammonia, and silica has 100% with respect to hydrogen sulfide and 93% with respect to ammonia. % Deodorization, but little antibacterial properties, and calcium oxide has a deodorization rate of 80% for ammonia and hydrogen sulfide, 85% for E. coli, and 95% for staphylococci. With a high antibacterial rate of 86% against Escherichia coli and 96% against staphylococci, 95% against ammonia, and 9 against hydrogen sulfide. It has been found that with the percentage of the deodorizing rate.
Titanium has a moderate deodorization rate of only 60% with respect to ammonia, has little deodorization with respect to hydrogen sulfide, and has almost no antibacterial property with respect to Escherichia coli and staphylococci. However, since titanium can be used as an active material for activating the effect of the ceramic by mixing with other ceramics, it was adopted in the present invention. Further, from the results in Table 2, it was found that each of the ceramics had a relatively high emissivity.

From the above results, the present inventor, by mixing two or more of the above-mentioned single-component ceramics, has a far-infrared radiation characteristic, an antibacterial property, a deodorizing property and a fungicide resistance, and a property against sanitary pests. Considering that composite ceramics having both repellent effects may be obtained, composite ceramics obtained by mixing 40 to 60% by weight of magnesia and 40 to 60% by weight of serpentine, or 20 to 40% by weight of magnesia, and 20 to 40% by weight of zinc oxide %, 20-40% by weight of silica and 20-40% by weight of titanium, or 20-30% by weight of magnesia, 2% of silica

Were measured for far-infrared emissivity, anti-mold resistance, repellency, antibacterial rate, and deodorization rate, and good measurement results were obtained.
Then, when the composite ceramics mixed at the most preferable mixing ratio of each ceramic shown in Table 3 were measured,
The measured values as shown in Table 4 were obtained. The composite ceramics obtained at each mixing ratio in Table 3 were defined as composite ceramics A, B, and C, respectively.

[0012]

[Table 3]

[0013]

[Table 4]

That is, each of the three types of composite ceramics A, B, and C has an extremely high emissivity of 92% or more in far-infrared ray, and has an antibacterial and deodorizing rate, anti-mold resistance, fleas and mites. It was also found that the repellent rate against such sanitary insects was extremely high.

Next, a method for producing a composite ceramic having far-infrared radiation characteristics, antibacterial properties, deodorizing properties, fungicide resistance and a repellent effect against sanitary insects, which is employed in the present invention, will be described in detail. I do. The particle diameter of each ceramic of each single component constituting the composite ceramics must be fine powder of 5 μm or less, and when these ceramics are mixed, the specific gravity, moisture, humidity, etc. With different characteristics,
Each of the above-mentioned ceramics as raw materials has a particle size of 5 μm.
Due to the following fine powder, agglomeration easily acts and it is not very easy to uniformly mix the ceramics.

The inventor of the present invention introduced the above-mentioned two or more single-component ceramics into a mixer at a predetermined ratio at a preferable mixing ratio as shown in Table 3 and mixed and stirred them.
A means of charging the mixture into a pulverizer and pulverizing the same, and further charging the pulverized substance into the mixer again, mixing and stirring, and then re-charging the pulverizer into the pulverizer for about 30 minutes. By adopting the method, it was possible to produce a uniformly mixed composite ceramics.

In order to stabilize the chemical properties of the uniformly mixed composite ceramics, the composite ceramics are fired by a firing machine at a calcining temperature of 200 to 500 ° C. to have far-infrared radiation properties and antibacterial properties. It is a composite ceramic having properties, deodorization and mold resistance, and a repellent effect on sanitary pests.

Incidentally, the hydrogen ion concentration of each ceramic which is a material of the composite ceramics has an alkaline property as shown in Table 5. Also, the composite ceramics composed of each of the above ceramics has an alkaline property as shown in Table 6.

[0019]

[Table 5]

[0020]

[Table 6]

The hydrogen ion concentration of the composite ceramics employed in the present invention in which each ceramic having the hydrogen ion concentration shown in Table 5 is composited is 200 ° C. to 500 ° C. as described above.
Since it is calcined at ° C., as shown in Table 6, it exhibits an extremely stable alkaline property, and the hydrogen ion concentration does not change with time. Further, these composite ceramics are crystallized by calcination to become composite ceramics having a function of generating electric field energy (cation). The reason why the composite ceramic exhibits an alkaline property is that impurities are gasified during the sintering process, so that the composite ceramic becomes more alkaline than a single component ceramic.

From Tables 5 and 6, the composite ceramics obtained by the above-described production method is a composite ceramic having cations, and becomes hydrogen ions in an alkaline region.
It is stable for a long time of not less than one year without change over time, and has a property that the deodorizing mechanism is a decomposing action. As a result, the composite ceramics obtained by the above-described manufacturing method has a far infrared radiation characteristic. In addition, it was found that it has both antibacterial and deodorizing effects.

That is, generally, the surface layer (wall) of a living bacterium is an anion, and therefore, has a neutral region (pH 7.0 to 7.0).
Although it is impossible to inhabit only in 5), cations are generated as the greatest characteristic of the composite ceramics obtained by the above-mentioned manufacturing method, so that the surface layer (wall) of the bacterial cells which are anions, At the same time as being destroyed by the cations of the composite ceramics, the bacterial cell protein is denatured and becomes difficult to breathe and dies.

Furthermore, the deodorizing action on hydrogen sulfide and ammonia is not a general action such as physical adsorption or chemical adsorption, but does not become saturated due to decomposition action. It is permanent and has no toxicity.

The method for processing buckwheat hulls as the material of the present invention is as follows:
Description will be made based on the vacuum processing apparatus of FIG. First, a composite ceramic having a particle diameter of 5 μm or less having the above-mentioned far-infrared radiation characteristics, having antibacterial properties and deodorizing properties, and having fungicide resistance and repellent effects against sanitary insect pests is put into the stirring tank 1 together with water and a dispersant. These are thoroughly mixed and stirred. Then, the ceramic solution in a valve (slurry) state obtained by mixing and stirring in the stirring tank 1 is supplied to a liquid sending pipe 2.
Is injected into the liquid storage tank 4 of the vacuum processing machine 3 via. A strainer 5 is provided between the liquid feed pipe 2 and the liquid storage tank 4 to remove dust and the like.

Next, buckwheat hulls to be processed are charged into a liquid injection tank 6 arranged on the lower surface of the liquid storage tank 4 of the vacuum processing machine 3.
The lid 7 is closed. Then, while the ceramic solution in the liquid storage tank 4 is injected into the liquid injection tank 6 through the injection pipe 8, the pressure in the liquid storage tank 4 and the liquid injection tank 6 of the vacuum processing machine 3 is reduced by the pressure reducing device 9. And preferably -1000 mmHg
~ -550 mmHg, particularly preferably -700 mmHg
Set to -500 mmHg. When the pressure in the liquid storage tank 4 and the liquid injection tank 6 of the vacuum processing machine 3 reaches the preferable pressure, the pores of the rind of the buckwheat hull inserted in the liquid injection tank 6 have a so-called “fluffy brush”. A phenomenon (generally a brushing phenomenon) occurs to open pores. When this happens,
The ceramics solution activated by the addition and mixing of the dispersant is injected into the opened pores. The phenomenon of the "fluff brush" generally occurs from the outer layer to 0.1 to 0.1 mm.
The range is up to about 2 mm.

Thereafter, the ceramic solution is transferred from the liquid injection tank 6 to the storage tank 4 by the drain pump 10 through the discharge pipe 11.
The return valve 12 is closed, and the inside of the injection tank 6 is again evacuated to remove the ceramics solution adhering to the pericarp of the buckwheat hull. Then, the removed ceramic solution is returned to the atmospheric pressure in the injection tank 6 and discharged into the storage tank 4, whereby the vacuum processing of the buckwheat hull is completed, and the lid 7 is opened to open the processed buckwheat husk. Take out the shell.

Next, since the buckwheat husks taken out of the vacuum processing machine 3 are immersed in the ceramic solution and contain a large amount of water, the buckwheat husks are charged into a dryer and dried.

The buckwheat hull is charged into the injection tank 6 of the vacuum processing machine 3, and the pores of the buckwheat hull are opened in a "fluffy brush" state.
In addition, the pores after the ceramic solution is injected and penetrated from the opening are completely restored to the original state in the drying step, and the opening is closed. Is sealed, and the processing of buckwheat husks having far-infrared radiation properties to be the material of the present invention, antibacterial properties, deodorizing properties and anti-mold resistance, and repelling effects against sanitary insects is completed.

The composite ceramic is preferably 2 to
It is recommended that 4% by weight, particularly preferably 3% by weight, be mixed with water and a dispersant, and the dispersant added to and mixed with the ceramic solution and water is not particularly limited, but is preferably hexametaphosphoric acid. Soda, Teapol
Or it is recommended to use any of the isooctane nonionic surfactants, and the amount added is between 0.10 and
It is preferably about 0.20% by weight, and most preferably about 0.15% by weight.

The above-mentioned processing method is a processing method in which a ceramic solution is pressed into a buckwheat hull using a dispersant, but the ceramic solution obtained by mixing only the water without adding the dispersant to the ceramic solution is mixed. Can be injected into the pores of the pericarp of the buckwheat husk. In this case, the time required for press-infiltration of the ceramic solution into the pores of the pericarp portion of the buckwheat husk is about twice as long as that when a dispersant is used.

The buckwheat hull processed by the above-mentioned processing method,
In addition to having far-infrared radiation characteristics, it is provided with antibacterial properties, deodorizing properties and anti-mold resistance, and a repellent effect against sanitary pests. FIG. 2 is a distribution diagram showing the far-infrared emissivity of the buckwheat hull processed by the above-mentioned processing method and the buckwheat husk for general use. It can be seen that the buckwheat husk by the above-mentioned processing method has a higher far-infrared emissivity.

It turned out that the effect was given.

That is, the skin (wall) of general live bacteria such as Escherichia coli and staphylococci is an anion, and therefore can only live in a neutral region (pH 7.0 to 7.5).
Since the single-component ceramics or the composite ceramics generate cations by far-infrared radiation, bacterial cells (walls), which are anions, are destroyed by the cations of the ceramics and, at the same time, bacterial protein is denatured. It becomes difficult to breathe and dies. In addition, it inhibits the growth of mold by cations and acts as a fungicide.

Further, the generation of sanitary pests such as fleas and ticks is prevented by the cations of the ceramics as in the case of the general living bacteria.

Furthermore, the deodorizing effect on hydrogen sulfide and ammonia is not a general effect such as physical adsorption or chemical adsorption, but is not saturated because of a decomposition effect based on far-infrared radiation. It has deodorizing power semi-permanently and has no toxicity.
