[0007]

BEST MODE FOR CARRYING OUT THE INVENTION The present inventor individually measured the antibacterial rate, deodorization rate and far-infrared emissivity of a single component ceramic, and found that the ceramics were excellent in antibacterial rate, deodorization rate and far-infrared emissivity And at the same time, mixing and stirring two or more of the above ceramics at a fixed ratio, and then having the far-infrared radiation characteristics obtained by calcining, having antibacterial properties and deodorizing properties, and having antifungal properties Mixed with water and a dispersant, or water
The obtained ceramic solution is introduced into a vacuum processing machine loaded with wood, the inside of the vacuum processing machine is decompressed, and the composite ceramics is sealed in a wall hole of a surface layer of the wood, thereby far-infrared radiation characteristics. A wood having antibacterial properties, deodorizing properties, antifungal properties and anti-mite properties was completed. Hereinafter, the present invention will be described in detail.

[0008] The antibacterial rate, deodorizing rate and average emissivity of a single component ceramic constituting the composite ceramics having far-infrared radiation properties and having antibacterial properties and deodorizing properties used in the present invention were measured. 1, the measured values shown in Table 2 were obtained.

[0009]

[Table 1]

[0010]

[Table 2]

From the results shown in Table 1, magnesia has an antibacterial rate of almost 100% against Escherichia coli and staphylococci, but has almost no deodorizing effect on 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 rate, but little antibacterial property, calcium oxide has 80% deodorization rate against ammonia and hydrogen sulfide, 85% against Escherichia coli and 95% against staphylococci Has an antibacterial rate and metamorphic serpentine is 86% against E. coli and 96% against staphylococci

% And 90% of hydrogen sulfide. 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 has found that by mixing two or more of the above-mentioned single-component ceramics, they have far-infrared radiation properties, and at the same time have antibacterial properties, deodorizing properties, antifungal properties, and anti-mite properties. Considering that a composite ceramic having the same may be obtained, magnesia is 40 to 60% by weight.

When the mite repellent rate, the antibacterial rate and the deodorization rate were measured, good measurement results were obtained. And Table 3
When the composite ceramics mixed at the most preferable mixing ratio of each ceramic shown in Table 4 were measured, the measured values as shown in Table 4 were obtained. The composite ceramics obtained at the respective mixing ratios in Table 3 were mixed with the composite ceramics A, B, and C, respectively.
This was also applied to Table 4.

[0013]

[Table 3]

[0014]

[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, and mite repellency. The rate was also found to be extremely high.

Next, a method for producing a composite ceramic having far-infrared radiation characteristics, antibacterial properties, deodorizing properties, antifungal properties and anti-mite properties, which is employed in the present invention, will be described in detail. 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. The characteristics of the ceramics are different from each other, and each of the ceramics, which are the raw materials, is a fine powder having a particle size of 5 μm or less. Therefore, it is very difficult to uniformly mix the ceramics because the agglomeration acts easily.

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 desired 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 characteristics and antibacterial properties. It is to be a composite ceramic having properties, deodorization, anti-mold and anti-mite properties.

The hydrogen ion concentration of each of the ceramics as the 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.

[0020]

[Table 5]

[0021]

[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 processing method of the present invention will be described based on the vacuum processing apparatus shown in FIG. First, a composite ceramic having the above-mentioned far-infrared radiation characteristic, antibacterial property and deodorizing property and having a particle size of 5 μm or less is put into a stirring tank 1 together with water and a dispersant, and these are sufficiently mixed and stirred. Then, the ceramic solution in a valve (slurry) state obtained by mixing and stirring in the stirring tank 1 is injected into the storage tank 4 of the vacuum processing machine 3 through the liquid feed pipe 2. A strainer 5 is provided between the liquid feed pipe 2 and the liquid storage tank 4 to remove dust and the like.

Next, wood to be processed is charged into a liquid injection tank 6 provided on the lower surface of the liquid storage tank 4 of the vacuum processing machine 3, and the lid 7 is sealed. Then, while injecting the ceramic solution in the storage tank 4 into the 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 preferably reduced to −1000 mmHg by a pressure reducer 9.
-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 so-called “fluffy brush” is applied to the wall pore cells in the surface layer of the wood loaded in the liquid injection tank 6. Phenomenon (generally a brushing phenomenon)
Occurs and the wall hole is opened. When this state is reached, the ceramic solution activated by the addition and mixing of the dispersing agent presses into the opened wall holes. The phenomenon of "fluff brush" generally occurs from the outer layer to 0.4 to
The range is up to about 0.8 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 surface layer of the wood. 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 wood is completed, and the lid 7 is opened to remove the processed wood. Take out.

Next, the wood taken out of the vacuum processing machine 3 is immersed in a ceramic solution and contains a large amount of water, so that the wood is loaded into a dryer and dried.

The wall hole is inserted into the liquid injection tank 6 of the vacuum processing machine 3 so as to be opened in a state of "fluffing", and the wall hole after the ceramic solution has been injected through the opening and penetrated. In this drying step, the opening is completely restored to the original state, the opening is closed, and the composite ceramics is sealed in the wall hole of the surface layer of the wood, and has far-infrared radiation characteristics of the present invention. Processing of wood having antibacterial, deodorizing, antifungal and mite-proof properties is completed.

The composite ceramic is preferably 3 to
It is recommended that 5% by weight, particularly preferably 4% by weight, be mixed with water and a dispersant. 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 0.18% 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 wood using a dispersant, but the ceramic solution obtained by mixing only the water without adding the dispersant to the ceramic solution is mixed. It is also possible to press-infiltrate into the wall hole of the surface layer of wood. In this case, the time required for the ceramic solution to be injected and penetrated into the wall holes in the surface layer of the wood is about twice as long as that when a dispersant is used.

The wood processed by the processing method of the present invention is
It has far-infrared radiation properties and has antibacterial and deodorizing power. FIG. 2 is a distribution diagram showing far-infrared emissivity of wood processed by the processing method of the present invention and general-purpose wood. It can be seen that the wood of the processing method of the present invention has a higher far-infrared emissivity.

Further, Table 7 shows the results of measuring the antibacterial efficiency of each type of wood processed by the processing method of the present invention, and Table 8 shows the results of the tree types processed by the processing method of the present invention. It is a table | surface which shows the result of having measured the deodorization rate of each different wood.

It turned out that it was provided with anti-mite properties.

That is, the surface layer (wall) of general living bacteria such as Escherichia coli and staphylococci is an anion, so that they 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.

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. In addition, cations inhibit the growth of mold and serve as a fungicide.

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 due to a decomposition effect based on far-infrared radiation. It has semi-permanent deodorizing power and has no toxicity.

Further, conventionally, the coating is generally applied to prevent the decay of the wood and prevent insects. However, since the wood obtained by the processing method of the present invention has a high hardness, the conventional coating operation is not performed. It is unnecessary, and has hydrophobicity especially against rainwater, is excellent in water resistance, and is also excellent in flame resistance, and can also act as a rot preventive and insect repellent.
