Hereinafter, the present invention will be described in detail.

[0006] The antibacterial rate, deodorizing rate and average emissivity of the single component ceramics 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.

[0007]

[Table 1]

[0008]

[Table 2]

From the results shown in Table 1, magnesia has an antibacterial rate of almost 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 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
Antibacterial rate and 95 against ammonia
% 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 radiating properties and at the same time have antibacterial properties, deodorizing properties, fungicidal properties and insect repellency. To obtain a composite ceramic having 40 to 60% by weight of magnesia and 40 to 60% by weight of metamorphic serpentine, or 20 to 40% by weight of magnesia and 20% of zinc oxide
-40% by weight, 20-40% by weight of silica and 20% of titanium

Then, when the composite ceramics mixed at the most preferable mixing ratios of the respective ceramics 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.

[0011]

[Table 3]

[0012]

[Table 4]

That is, each of the three types of composite ceramics A, B, and C has a far-infrared emissivity of 92% or more and has an extremely high emissivity, and has an antibacterial rate, a deodorization rate, a mold resistance, and a sanitary insect pest. It was also found that the repellent rate showing insect repellency was extremely high.

Next, a method for producing a composite ceramic having far-infrared radiation characteristics and antibacterial properties, deodorizing properties, fungicidal properties and insect repellency, 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 manufacture a uniformly mixed composite ceramics.

In order to stabilize the chemical characteristics 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. Nature, deodorization,
It is a composite ceramic having fungicidal and insect-proof properties.

The hydrogen ion concentration of each ceramic as a material of the composite ceramics is alkaline 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.

[0018]

[Table 5]

[0019]

[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 was baked at ℃, it has very stable and alkaline properties as shown in Table 6. 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 4 to 6, it has been proved that the composite ceramics obtained by the production method is a composite ceramic that generates cations by far-infrared radiation and becomes hydrogen ions in an alkaline region. Further, the deodorizing mechanism has a property of decomposing action, and as a result, the composite ceramics obtained by the manufacturing method has both antibacterial properties and deodorizing actions in addition to having far-infrared radiation properties. I understood.

That is, the antibacterial mechanism of the composite ceramics is that the surface layer (wall) of general living bacteria such as Escherichia coli and staphylococci is an anion, and thus the neutral region (pH)
7.0 to 7.5), but the cations are generated as the largest characteristic of the composite ceramics obtained by the above-mentioned production method. At the same time, the surface layer (wall) is destroyed by the cations of the composite ceramics, and at the same time, the bacterial protein is denatured and becomes difficult to breathe and is killed.

The deodorizing mechanism of the composite ceramics against hydrogen sulfide, ammonia and the like is not a general action such as physical adsorption or chemical adsorption, but is not saturated due to decomposition action. Has semi-permanent deodorizing power. The composite ceramics has no toxicity.

Furthermore, the composite ceramics have a repellent effect of exhibiting insect repellency against sanitary pests such as fleas and mites by cations generated by far-infrared radiation. Then, the cations inhibit the generation or growth of fungi, thereby fulfilling the function of preventing fungi.

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 chips to be processed are 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. It is recommended that the wood chips be enclosed in a net bag to prevent the wood chips from spreading. The size of the wood chips to be sealed in the net bag is not particularly limited, but is preferably set to a size of about 1 to 3 mm, and the amount of wood chips to be sealed in the net bag is particularly limited. Although it is not necessary to do so, it is recommended that it is preferably about 5 to 10 kg.

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 increased. By the decompressor 9, preferably -1000 mmHg to -55
0 mmHg, particularly preferably -700 mmHg to -50
Set to 0 mmHg. When the pressure in the liquid storage tank 4 and the liquid injection tank 6 of the vacuum processing machine 3 reaches the above-described preferable pressure, the so-called “fluffy taki” is applied to the wall pore cells in the surface layer of the wood chips loaded in the liquid injection tank 6. (Generally, a brushing phenomenon) occurs to open the wall hole. When this happens,
The ceramic solution activated by the addition and mixing of the dispersing agent is injected into the opened wall hole by press-fitting. The phenomenon of the "fluff brush" generally occurs from the outer layer to 0.2 to 0.2 mm.
The range is up to about 3 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 evacuated again to remove the ceramic solution adhering to the surface layer of the wood chips. Then, the removed ceramic solution is returned to atmospheric pressure in the injection tank 6 and discharged into the storage tank 4, whereby the vacuum processing of the wood chips is completed, and the lid 7 is opened to open the processed wood chips. Take out the net bag containing.

Next, since the wood chips taken out of the vacuum processing machine 3 are immersed in the ceramic solution and contain a large amount of water, the wood chips are taken out of the net bag or sealed in the net bag. Leave it in the dryer as it is and let it dry.

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 chips, and has the far-infrared radiation characteristics of the present invention. At the same time, the processing of wood chips having antibacterial properties, deodorizing properties, fungicidal properties and insect repellent 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 press-fitted into wood chips using a dispersant. The ceramic solution obtained by mixing only water with no addition of the dispersant to the ceramic solution is added. It is also possible to press-infiltrate into the wall hole of the surface layer of the wood chips. In this case, the time required for press-infiltration of the ceramic solution into the wall holes of the surface layer of the wood chips is about twice as long as the case where a dispersant is used.

The wood chips processed by the processing method of the present invention have far-infrared radiation properties, and are imparted with antibacterial and deodorizing power. FIG. 2 is a distribution diagram showing the average far-infrared emissivity of the wood chips processed by the processing method of the present invention and the wood chips before processing, and the wood chips by the processing method of the present invention have higher far-infrared emissivity. Proven.
