Description

  The present invention relates to a method for producing a material / member (hereinafter referred to as far-red emission, sterilizing material) that emits far-infrared rays using astronomical stone or tourmaline (raw tourmaline) as a raw material, and has a sterilizing and antifouling effect. Further, the present invention relates to a far-red emission and sterilizing material produced by this method and a method of using the far-red emission and sterilizing material.

  Light rays exceeding the wavelength of 3.0 μm are called far infrared rays, and it is said that when exposed to these far infrared rays, living organisms promote blood flow and cells are activated. Since far-infrared rays are naturally emitted from rocks and ceramics, health appliances and health foods using these are on the market. According to the following non-patent document 1, among the far infrared rays, those having a wavelength of 4 to 14 μm, especially those around 9 μm, in addition to the above-mentioned effects, are also added with a physiologically active action and a growth promoting action. It is stated to be more useful. For this reason, the author of this document distinguishes far-infrared rays in this wavelength range from ordinary far-infrared rays and names them as growth rays.

  Rocks that emit a lot of growth light (growth light expression rocks) are named Amaterite because of the following place names where rocks that specifically emit growth light with a wavelength of around 9 μm are collected. So this is the common name. This amaterite is collected all over Japan, but according to the above-mentioned literature, a kind of granite collected in the location of Hinokage-cho, Nishiusuki-gun, Miyazaki Prefecture, and the scientific name “Mt. In particular, it is stated that the nurturing rays are emitted strongly.

  One of the reasons for this is that it is a kind of meteorite that was exposed to sunlight intensely in the vicinity. Therefore, it is said that it may specifically emit the growing light. In addition, Amaterite, especially “Midachi”, is also known to release strong negative ions, which are also considered good for the body. This austerite stone is finely powdered for drinking water for the purpose of healing diseases or promoting health, and granulated and immersed in a bathtub.

  The following Patent Document 1 discloses a technique in which an aqua rock called “Fukushima stone” collected in Fukushima Prefecture is fired at 1200 ° C. and irradiated with ultraviolet rays. Among them, “Fukushima stone” is originally described as having a photocatalytic function for deodorizing, purifying air and water, and firing and irradiating with ultraviolet rays is nothing but to strengthen this photocatalytic action. In this regard, it differs from Amaterishi, which emits a nurturing ray.

By the way, there is another tourmaline (tourmaline rough) collected in Brazil, India, etc., as another rock that emits nurturing rays. It is also conceivable to use Amaterite and tourmaline together. In addition, it is known that tourmaline also emits negative ions in addition to the growth light, like Amaterishi.

  The problem to be solved by the present invention is to give a photocatalytic function that exerts a further sterilization and antifouling effect on Asterite and tourmaline that emits nurturing rays and negative ions to promote bioactivity and growth promotion action, Both functions are made to occur at the same time, but at this time, by adding one function, the other function is complementarily enhanced, and the durability and life of the function in the product are prolonged. .

Under the above-described problems, the present invention provides a method for producing a far-red emission and bactericidal material according to claim 1 that takes the following steps.
a. Crushing a celestite that specifically emits far-infrared rays having a wavelength of 4 to 14 μm into particles having a particle size of 0.2 mm or less b. Add and knead the plasticizer that is pulverized to 0.1 mm or less to the granules c. Add a binder to the kneaded granules and granulate them into spheres with a diameter of about 2 to 20 mm. D. The granulated spheres are dried and then fired at 1000 to 1200 ° C. e. Immerse the fired spheres in a fine particle solution in which photocatalyst fine particles are dispersed. F. The sphere coated with the fine particle solution is heat-treated at 300 to 800 ° C.

  According to the present invention, a far-red emission and sterilizing material having a spherical shape with a diameter of about 2 to 20 mm having a sterilizing and antifouling effect by a photocatalytic action as well as a growing light effect and a negative ion effect can be produced. The far-red emission and sterilizing material produced in this way increases the fixing power of the photocatalyst particles, particularly by firing, and does not diminish its function. The steps a to c are steps for facilitating the formation of spheres in which the particles of aetherite are evenly arranged, and the step e is a step for depositing photocatalyst fine particles on the surface of the sphere, d The step (2) is a step of increasing the strength of the sphere and permanently holding the photocatalyst fine particles in a state in which the action is suitably expressed, and the step (f) is a step of strengthening the fixation of the photocatalyst fine particles.

Hereafter, the manufacturing method of the far-red and sterilizing material according to the present invention will be described. Among the Amaterite stones, the raw stone of “Tatechitsu conglomerate” collected at the above-mentioned ground has the following composition.
Component ratio (volume%)
SiO ₂ 64.4
Al ₂ O ₃ 16.5
Fe ₂ O ₃ 6.4
Na ₂ O 3.4
CaO ₂ 3.2
MgO ₂ 2.6
K ₂ O 2.2
Other 1.3

  As far as this is seen, it has almost the same components as general granite. In addition, there is no big difference in the composition of “Tatechi” and Amaterite collected elsewhere. However, it is said that “Midachi conglomerate” is a kind of meteorite, and this differs in that it radiates electromagnetic waves (growth rays) with a wavelength of 4.0 μm to 14.0 μm, especially around 9 μm. In this respect, it can be said that it is preferable to use this “Mt. In the present invention, the raw stone of Amaterite is pulverized by a pulverizer (jet mill). The particle size of the pulverized product is 0.2 mm or less, preferably 0.1 mm or less, considering the suitability of kneading and granulation with the addition of a binder.

  Next, plasticity is imparted to the pulverized granules to facilitate granulation, and a plasticizer for uniformly dispersing the granules is added and kneaded. The plasticizer is preferably an inorganic material such as bentonite or refractory clay, and pulverized to a particle size of 0.1 mm or less, preferably 0.043 mm or less and added in an amount of 3 to 30% by weight. If the particle size of the plasticizer exceeds 0.1 mm, the particle size will be the same as or larger than the particles, so that sufficient plasticity cannot be imparted to the kneaded product, and the amount added is too large. And the original function of Amaterite is lost, and if it is too little, the particles are bonded to each other and plasticity cannot be imparted.

  And this kneaded material is granulated using rotary granulators, such as a pan petalizer and a malmerizer. At this time, a binder (binding material) is added to improve the granulation property. For this binder, organic binders such as dextrin and polyvinyl alcohol are suitable. In the former, a 5 to 15% by weight aqueous solution is purified, and in the latter, a 1 to 5% by weight aqueous solution is purified and sprayed at the time of granulation. Add at 30% by weight. In addition, an appropriate amount of water may be added to further improve the granulation property. The size of the granulation is made into a spherical shape with a diameter of about 2 to 20 mm by sieving in consideration of the ease of handling of the finished product. The shape of the product is not limited to a spherical shape, and may be an irregular shape. Further, it may be formed into a special shape using a mold, for example, a flat body such as a tile.

  Next, the granulated spheres are packed in a fire-resistant round shell or a square bowl and placed in a firing kiln and fired. This firing is for the purpose of enhancing the strength of the product (sphere) by perfecting the crosslinking effect by the binder, and at the same time, for removing the moisture of the sphere and increasing the porosity of the surface. The photocatalyst fine particles described later enter the pores to express their functions. However, if the porosity is too high, the photocatalyst fine particles will penetrate too deeply and will not function sufficiently, and if it is too small, the function will be sufficient. However, there is no persistence due to peeling.

  Therefore, the porosity is set according to the intended use of the product, such as the required strength and durability of the photocatalytic function, and this porosity can be adjusted by the firing temperature. Firing is generally performed at 1000 to 1200 ° C. for about 2 to 10 hours. The higher the firing temperature, the smaller the porosity. Specifically, the porosity is 20 to 30% at 1000 ° C, 10 to 20% at 1050 ° C, and 5% or less at 1100 ° C. What is necessary is just to adjust a porosity. In addition, when the sustainability of the photocatalytic function is not necessary, this firing step may be omitted.

The apparent porosity (measured by JIS R2205-1992) when a sphere having a sphere diameter of 13 to 16 mm is fired at various temperatures for about 3 hours is shown below.
Firing temperature (° C) Apparent porosity (%)
1000 23.0
1050 12.0
1100 0.7

When the above processing is completed, photocatalyst fine particles (hereinafter referred to as fine particles) that cause the photocatalytic function to be applied are deposited on the surface of the sphere. The photocatalytic function means that when irradiated with light (ultraviolet rays), electrons having a strong reducing action and holes having a strong oxidizing action are simultaneously generated on the surface of fine particles having a particle diameter of about 10 nm and exist in the atmosphere of the fine particles. It refers to the function of decomposing living organisms by redox action. This decomposing function is intense and destroys the organism itself. Fine particles having a photocatalytic function include oxides of titanium, strontium, cadmium, zinc, tin, copper, and silver. Among these, titanium oxide (TiO ₂ ) has the strongest photocatalytic function.

  At this time, since it is not easy to directly apply the fine particles, it is suitable to use a fine particle solution in which the fine particles are dispersed in a dispersion medium. This fine particle solution is commercially available, and recently, a product obtained by dispersing fine particles in a harmless aqueous emulsion is commercially available (for example, trade name “Inner and Outer Techno Coat” manufactured by Inner and Outer Technos Co., Ltd.). For the deposition, the fine particle solution may be applied or sprayed onto the sphere, but direct immersion and kneading are easy and quick.

  And the thing which adhered the fine particle solution to the surface of a sphere is heat-processed at 300-800 degreeC for about 1 hour. This heat treatment increases the film density and fixing force of the coating to prevent peeling, but this heat treatment can be omitted for those used under the condition that the spheres do not rub against each other. Moreover, when the photocatalyst fine particle solution (trade name “CX-01”) hybridized with copper and titanium dioxide manufactured by Inner and Outer Technos Co., Ltd. is used, the photocatalytic function can be expressed even in a dark place.

  Molded products obtained by the above, obstruction of blood vessels due to blood flow enhancement action based on Amaterite's original growth light and negative ions, coldness, menstrual pain, infertility, constipation improvement and diabetes due to cell activation action, liver cirrhosis, It is effective for pulmonary sclerosis, neuropathy, and hair loss, and is also effective for repairing skin ulcers and beauty. And by giving a photocatalytic action to this, functions, such as antibacterial, sterilization, deodorizing, anti-fouling, antifouling, air purification, and water purification, are given.

  In addition, according to the results of tests by the inventors, the far-red emission and sterilizing material of the present invention does not have both far-infrared and negative ion effects and photocatalytic effects, but enhances other effects. It has been confirmed that there is an enhancement effect. The reason is not clear, but Amaterishi also emits a photocatalytic function, and photocatalyst particles also emit far infrared rays and negative ions. It seems to be demonstrating.

  By the way, although the above is an example using Amaterite as what emits a nurturing ray, this may be replaced with tourmaline (tourmaline raw stone), or a mixture thereof may be used. Tourmaline, like Amaterishi, emits nurturing rays and negative ions, and can benefit from both. The processing and operation of tourmaline are the same as in the case of Amaterasu stone.

  Furthermore, recently, a charge transfer type catalyst that performs a redox action without requiring any light irradiation has been found, and this may be used. This is because the electron donating elements such as molybdenum and tungsten are moved to the electron accepting elements such as aluminum, tin, titanium, and iron by the electron carrier elements such as zirconia and manganese. The element receives an electron transferred to the electron accepting element and performs a reduction reaction, and an oxidation center element such as lithium, beryllium, and barium receives a hole that has escaped from the electron donating element and performs an oxidation reaction (for example, JP 2002-1121). Note that these can be used in the same manner as the photocatalyst fine particles by being dispersed in a dispersion medium such as an emulsion.

  Next, how to use the above materials such as far-red emission and sterilization will be explained. In the case of a sphere, it can be placed in a suitable number of nets and hung in a bathtub or directly placed in a bathtub. Conceivable. Thereby, scale etc. are decomposed | disassembled by a photocatalyst function, and a bather can be bathed with sufficient nurturing light. The photocatalytic function also has an action of sterilizing harmful microorganisms such as Legionella bacteria.

  Furthermore, the odor prevention, clarification and antifouling functions remove turbidity of bath water, odor and dirt on the bathtub, and a comfortable bathing can be performed. On the other hand, when drinking water is filtered with this, chlorine is decomposed, and you can drink healthy water that emits far infrared rays and negative ions. Furthermore, what was made into the flat body should just be used as a covering material and wall material of a bathroom or a toilet room in which disinfection and deodorizing are calculated | required especially. This effect is semi-permanent.
