JP2000288096A - Tourmaline molding consisting of silver as carrier - Google Patents

Abstract

PROBLEM TO BE SOLVED: To provide a tourmaline molding which has a living active effect and antimicrobial effect and may be carried or worn at all times by using the silver prepared by mixing a prescribed amount of silver with a prescribed amount of tourmaline ore powder having an average grain size of a prescribed range as a carrier. SOLUTION: The tourmaline molding consists of the silver prepared by mixing 20 to 99.9 wt.% silver with 0.1 to 80 wt.% tourmaline ore powder having the average grain size of 0.1 to 400 μm as the carrier. The preferable tourmaline ores include schorl tourmaline, rubellite tourmaline, elbait tourmaline, dravite tourmaline, etc., and the tourmaline ores exclusive of the schorl tourmaline known as black tourmaline are more preferable. The quantity of minus electricity generation of the tourmaline ores is intrinsically extremely slight but is known to be tremendously increased in voltage by pulverization. For example, the voltage rises as high as >=1,000,000 volts with the fine powder of 0.3 μm. Accordingly, the powder having the grain size of 0.1 to 400 μm is preferred.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

The present invention relates to a pet-related article which aims to utilize a tourmaline ore having a high bioactive element such as negative ion generation and infrared radiation more efficiently and to provide a bioactive effect with antibacterial properties. The present invention relates to tourmaline moldings using silver as a carrier that can be used in a wide range of fields such as accessory articles.

2. Description of the Related Art In recent years, attention has been paid to the excellent therapeutic effect of negative ions on living bodies. This negative ion can also be generated by a machine such as corona discharge. In this case, the number of negative ions generated suddenly changes from 0 to a value of 500,000 or more. (According to a survey by Adan Mining Central Research Laboratory Co., Ltd.). Further, such a generation method using a machine is not only limited in its use range but also expensive, and it is difficult to carry or wear it on a daily basis.

On the other hand, tourmaline ore called tourmaline is a polar crystal and is known to have properties such as generation of negative ions and emission of far infrared rays. At present, there are health promotion products, growth promotion products, air purification products, water quality improvement products, antibacterial products, etc., which utilize such tourmaline ore properties, but they are designed to be always carried or worn. It is not possible to expect a function with high fashionability, for example, as accessories. Also, as accessories, only tourmaline ore is used as it is as a jewel.

[0004] Further, there are known those in which tourmaline powder is woven into fibers and those in which a resin or rubber is carried.
However, since the electric resistance of tourmaline ore is 10 ¹⁰ Ω, when a material having a high insulating property is used as a carrier,
It is not expected that the electrical properties of tourmaline ore will be fully exploited.

Further, it is known that the composition of tourmaline ore changes at 950 ° C., and the materials that can be used as the carrier are limited to those that dissolve at low temperature, such as resin and rubber. For example, in Japanese Patent Application Laid-Open No. 08-354856, in a method for producing a composite material of aluminum or / and an aluminum alloy, the particles of tourmaline are formed into a molten aluminum or / and aluminum alloy at the time of agglomeration.
Or, it is described that it is added at the time of casting, but there is no description suggesting the temperature at the time of mixing.

DISCLOSURE OF THE INVENTION The present invention has been made to solve these problems, and the silver satisfying the conditions for effectively bringing out the electrical properties of tourmaline ore and having excellent design properties. An object of the present invention is to provide a tourmaline molded article which has a bioactive effect and an antibacterial effect and can be carried or worn at all times by selecting as a carrier.

[0007]

Means for Solving the Problems The present inventor has studied to solve the above-mentioned problems, and as a result, it is necessary to generate electricity by applying pressure as a necessary element for sufficiently extracting the electrical characteristics of tourmaline ore. There are piezo electricity and pyro electricity that generate electricity by applying heat.
Attention was paid to the point that the properties can be brought out by causing an external action, that is, a temperature change and / or an action of repelling electricity. The present invention has the highest thermal and electrical conductivity among metals, 1.47 (10 ⁻⁸ Ω · m) at 0 ° C.
The present invention relates to a tourmaline molded product using silver as a carrier, wherein silver having an electric resistance of 2.08 (10 ⁻⁸ Ω · m) at 100 ° C. is used as a carrier.

Although the original melting point of silver is 960 ° C.,
By adding a binder to silver powder and kneading it in a clay-like manner, a silver shaped product can be obtained by baking at a temperature lower than the original melting point of silver, that is, at a temperature not exceeding 950 ° C. at which the composition of tourmaline ore changes. It is known. For example, Japanese Patent Application Laid-Open No. 8-269503 discloses that silver powder is kneaded with an organic binder aqueous solution, dried, and then melted to an original melting point of 96.
By baking at a temperature of 710 to 890 ° C. 70 to 250 ° C. lower than 0 ° C. for 5 minutes or more, a silver molded article is obtained. Accordingly, the object of the present invention is to provide tourmaline ore,
After kneading the silver powder and the binder and shaping into a desired shape, the incinerator equipped with a thermosensor was used at 900 ° C.
This can be achieved by providing a tourmaline molded article using silver obtained by baking at the following temperature.

In the present invention, the amount of tourmaline ore to be kneaded with the silver powder and the binder is adjusted from 0.1% to 5% of the total amount according to the purpose, and the mixture is formed into a desired shape. Thus, a tourmaline molded product using silver as a carrier having excellent design properties can be used without impairing the original brightness of silver and hard to be oxidized.

[0010]

DESCRIPTION OF THE PREFERRED EMBODIMENTS Preferred tourmaline ores in the present invention include shawl tourmaline, ruberite tourmaline, erbaite tourmaline, and dravite tourmaline, and are known as black tourmaline when design is important such as accessory articles. Tourmaline ores other than shawl tourmaline are desirable.

Also, the amount of negative electricity generated from tourmaline ore is extremely weak, and the shawl tourmaline is 2 cm.
² , the current was 0.06 mA, the voltage was 5.3 V, and luberite tourmaline and elbaite tourmaline 2c were used.
In the case of m ² , the current is 0.06 mA and the voltage is 3.3 V. It is known that the voltage is significantly increased by pulverizing them. It has reached 10,000V or more. Therefore,
The powder of tourmaline ore preferably has a particle diameter of 0.1 to 400 μm.

Further, in the present invention, 0.1 to 80% by weight of the tourmaline ore powder or gel tourmaline is used.
On the other hand, by adjusting the compounding in the range of 20 to 99.9% by weight of silver powder, a shaped article suitable for the purpose can be obtained. For example, when a transparent tourmaline ore powder having a diameter of 10 μm or less is used and the blending amount is 10% by weight or less of the total amount, the jewelry of silver can be maintained and an optimal shaped article as an accessory can be obtained. Further, when the shale tourmaline ore powder is blended in an amount of 5% by weight or more, the bioactive effects such as the electric properties and infrared radiation properties of the tourmaline ore increase in proportion to the blending amount, and the molded article is inexpensive. However, jewelry is lost in inverse proportion. In order to produce a shaped article having a well-balanced jewelry and bioactivity effect, a powder of lithiatourmaline ore having a diameter of 40 μm or less or a gel-form tourmaline ore is 5 to 20% by weight of the total amount.
It is desirable to mix in the ratio of.
