、本発明に到ったのである。BACKGROUND OF THE INVENTION Conventionally, ceramic products such as ceramics and refractories have been widely used as storage containers or packaging containers for various food and drink products. By the way, in order to prevent the food and drink contents from spoiling, methods of processing the food and drink products themselves, such as a method of mixing a preservative into the food and drink products or a method of heat sterilizing the food and drink products, have been conventionally employed. However, this method has the disadvantage of being unreasonable because it requires a processing step for the food and drink. Therefore, the present inventors imparted antibacterial properties to the ceramic products themselves, such as ceramics, which are storage containers or packaging containers for food and beverages.
The present invention was achieved by attempting to prevent food and drinks from spoiling without undergoing any processing.

The present invention relates to a raw material powder for ceramics, an antibacterial composition for ceramics comprising the same, and a ceramic product obtained using this composition. In the present invention, clay, which is well known as a raw material powder for ceramics, can be used as the raw material powder for ceramics. In addition to clay, we also have stone, stone, stone,
Silica stone 9 Limestone, dolomite alumina, china clay, bentonite, etc. are used. Furthermore, silicon dioxide, aluminum oxide, sodium oxide, potassium oxide, iron oxide (■),
Calcium oxide, magnesium oxide, titanium oxide (■)
Inorganic oxides including metal oxides such as diboron trioxide and the like can also be used. The particle size of the raw material powder for ceramics is preferably the same as that generally used in manufacturing ceramics, and is, for example, about 1 to 1O·μ. In the present invention, as the radioactive mineral, for example, fergusonite, perochite, monazite, etc. are used. These are naturally occurring, such as the Namikata region of Ehime Prefecture, the Iizaka region of Fukushima Prefecture, the Yamaguchi region of Nagano Prefecture, the Oro region of Kyoto Prefecture, the Abusumi region of Fukushima Prefecture, the Ishikawa region of Fukushima Prefecture, the Naegi region of Gifu Prefecture, and Fukuoka Prefecture. It is produced in the Kotoge region of the prefecture, Australia, India, Malaysia, etc. The composition of these radioactive minerals is radium oxide, thorium oxide, niobium oxide, tantalum oxide, yttrium oxide, cerium oxide, silicic acid,
Iron oxide, aluminum oxide, titanium oxide, calcium oxide, manganese oxide, magnesium oxide. This is a conflict between manganese oxide, erbium oxide, etc. Radiation is irradiated from thorium oxide, etc. in this composition. Therefore, as a radioactive mineral, especially thorium oxide 0.05
It is preferable to use one containing up to 2.0% by weight. When thorium oxide exceeds 2.0% by weight, the amount of radiation irradiated increases, resulting in poor working conditions at manufacturing sites for the antibacterial composition for ceramics according to the present invention and ceramic products made from this composition. There is a tendency to Further, if the thorium oxide content is less than 0.05% by weight, the amount of radiation irradiated becomes too small, and the antibacterial properties tend to decrease. Note that the particle size of the radioactive mineral powder is preferably as fine as possible, and is generally about 0.5 μm to 3 μm. In the present invention, silver minerals include, for example, kigginite, kakuginite, sylvanianite, miasilite, petzite, anginite, hariginite, norkouginite, tankouginite,
Polypus ore etc. are used. Further, minerals containing less silver than the above-mentioned minerals can also be used. That is, if the silver content of the silver mineral is o, 0
If the amount is 0.05% by weight or more, it can be used in the present invention. It is known that an antibacterial effect can be obtained by bringing silver into contact with another object, but when the content of silver in silver minerals is less than o, oos weight percent,
The antibacterial effect of silver tends to decrease. The particle size of the silver mineral powder is preferably as fine as possible, and is generally 0.5μ to 3μ.
A value of around μ is good. The zinc oxide used in the present invention is so-called zinc white or zinc. It has antibacterial properties and is also used as a filler in pharmaceuticals and cosmetics. The finer the particle size of zinc oxide, the better, and generally about 0.5 μm to 3 μm is preferable. The antibacterial composition for ceramics according to the present invention comprises raw material powder for ceramics, and the above radioactive mineral powder and/or silver mineral powder and/or zinc oxide. The content of the radioactive mineral powder, etc. in the antibacterial composition for ceramics is preferably about 1 to 70% by weight. If the content of radioactive mineral powder, etc. is less than 1% by weight,
There is a tendency for the amount of radiation to be irradiated to decrease. Furthermore, if the content of radioactive mineral powder or the like exceeds 70% by weight, the amount of the ceramic raw material powder, which is a coupling agent, will be relatively reduced, and there will be a tendency that only ceramic products with weak strength will be obtained. The antibacterial composition for ceramics according to the present invention can be obtained by simply mixing radioactive mineral powder or the like into raw material powder for ceramics. Then, add water to this composition and knead it well in a clay kneader, then mold it using methods such as casting, potter's wheel molding, compression molding, etc., and appropriately combine bisque firing, shime firing, single firing, overglaze firing, etc. By firing, the ceramic product according to the present invention can be obtained.

Raw material powder for ceramics: 70 parts by weight Fergussonite (particle size 3 μm) 30 parts by weight To 100 parts by weight of this composition, 50 parts by weight of water was added and kneaded in a clay kneader to obtain high clay. Using this high soil, potter's wheel molding was carried out to form the shape of a test tube. This was dried and fired at about 1000°C for 2 days to obtain a ceramic test tube. In order to confirm the antibacterial properties of the test tube obtained in Example 1,
The following experiment was conducted. In a sterile 500ml conical Scotch containing 250a+1 of sterile phosphate buffered diluted water, 1 cup of cooked rice was added immediately after cooking.
g was added aseptically, and the cooked rice was pulverized using a sterilized glass rod. Next, take this 1+al into a sterile test tube using a sterile pipette, add 9 ml of sterile phosphate buffered dilution water, mix well, and use this as a sample. Thereafter, the above sample In+ was added to the ceramic test tube obtained in Example 1 containing 10 ml of thioglycolate culture medium.
1 was added, and the mixture was left at a temperature of 35±1° C. for 48 hours. Then, it was visually confirmed whether or not bacterial growth was observed, but no bacterial growth was observed. On the other hand, a culture test of bacteria similar to the above was conducted using a commonly available glass test tube. As a result, bacterial growth was visually observed.

勿論である。As explained above, the antibacterial composition for ceramics according to the present invention contains radioactive mineral powder and/or silver mineral powder and/or zinc oxide powder, so water is added to this composition. In addition, ceramic products that are molded into a predetermined mold and fired also contain powders such as radioactive minerals. Since ceramic products are porous, they can be irradiated with radiation more easily than radioactive mineral powders, and mineral powders and zinc oxide powders are more likely to come into contact with the outside air. Therefore, if various foods and beverages are stored or packaged in this ceramic product, the foods and beverages may be irradiated with radiation or come into contact with silver mineral powder, etc., resulting in the growth of bacteria in the foods and beverages. is suppressed or bacteria are killed,
This has the effect of preventing spoilage of foods and drinks. Moreover, even if this ceramic product is coexisted with various foods and drinks, it is effective in preventing the foods and drinks from spoiling. Furthermore, the ceramic product according to the present invention can also prevent bad odors that occur due to the decay of foods and drinks. Although the ceramic products according to the present invention are mainly used in storage containers and packaging containers for food and beverages, it is of course possible to use them in various other applications.
