Abstract

PROBLEM TO BE SOLVED: To provide a health material usable for personal articles without harming negative ion effect, by uniformly dispersing fine powder of an artificial functional mineral into synthetic resin such as polyurethane resin and adhering the synthetic resin on the surface of sheet substrate in a thin film or dots. SOLUTION: A mineral containing radioactive elements and ceramics as a main component is finely crushed and burnt, and further crushed to the average particle diameter of about 3μ. This fine powder is put into a little amount of solvent and the solvent is gradually increased while kneaded by a disperser until the mineral and the solvent becomes equal amount to make a blended liquid into which the fine powder of the mineral is homogeneously dispersed. Next, this blended liquid is mixed with polyurethane resin, pigment, and a solvent and kneaded in a disper, and a thin film 3 with thickness of 5-100μ is formed by the thin film forming method from the synthetic resin into which mineral fine powder is homogeneously dispersed. The thin film 3 is adhered on the surface of a sheet substrate 1 to obtain a sheet type health material.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for producing a sheet-like health material for increasing negative ions in the air, which is considered to be good for health.

[0002]

2. Description of the Related Art Micro-organic ores containing radioactive elements such as uranium and thorium increase negative ions in the air, and the negative ions adjust the pH value of blood in the body to improve blood circulation, Promotes metabolism and, as a result,
It shows stiffness in the shoulders, recovery from tiredness, or can keep the body warm by keeping it cool, and can remove odors from the body by sterilizing, purifying, deodorizing, etc. to maintain cleanliness and keep food fresh. It is known to have health and other beneficial effects, such as longer duration.

Therefore, such an artificial functional ore fine powder is kneaded into fibers constituting clothes, bedding, etc., or into synthetic rubber constituting shoes, etc., and negative ions are formed by the action of ionizing radiation. It has been done so far to make it useful for health.

However, when the artificial functional ore is blended in a synthetic resin such as polyurethane resin or PVC resin, the increase of negative ions is hindered, so that the effects of negative ions as described above are sufficiently exerted. There was a problem that it was not done.

[0005]

Therefore, the present invention is to provide a method for producing a sheet-like health material that can be used for various personal items without impairing the negative ion effect exhibited by the artificial functional ore. It is a thing.

[0006]

Therefore, in the method for producing a sheet-shaped health material of the present invention, a fine powder of artificial functional ore that negatively ionizes the surrounding air by the action of ionizing radiation is used in a synthetic resin such as polyurethane resin. In a uniform manner, and the synthetic resin is adhered to the surface of the sheet-shaped base material in the form of a thin film or dots. Further, the present invention is characterized in that, in the above-mentioned method for producing a sheet-like health material, the fine powder of artificial functional ore has an average particle size of about 3 microns, and a thin film of synthetic resin has a thickness of 5 to 100 microns. To do.

In addition to the above polyurethane resin, polyvinyl chloride, acrylic resin, polyolefin resin, polyester resin, polycarbonate resin, polyester resin, natural rubber, styrene rubber, nitrile rubber, silicone can be used as the synthetic resin in the present invention. Examples include simple substances such as rubber, mixtures thereof, and copolymers. There are various kinds of artificial functional ores that increase negative ions, but the composition was adjusted by using ceramics such as SiO ₂ and Al ₂ O ₃ so that the radioactive content was 370 becquerels or less with a small amount of radioactive elements such as uranium and thorium. Stuff used. The ceramics used for adjusting this component emits far infrared rays, and thus can expect a synergistic effect. Examples of the sheet-shaped base material include woven cloth, non-woven cloth, paper, natural leather, polyvinyl chloride sheet, polyurethane sheet,
Alternatively, various composite materials or the like can be selected according to the application.

[0008]

BEST MODE FOR CARRYING OUT THE INVENTION Next, embodiments of the present invention will be described. Si containing radioactive elements such as uranium and thorium
Ore containing ceramics such as O ₂ and Al ₂ O ₃ as the main component is finely pulverized and the components are adjusted so that the radioactivity thereof is 370 becquerel or less, which is a safety standard for the human body. Then, the fine powder is baked at about 1200 ° C. to remove water, impurities, etc. in the powder. Then, this is further finely pulverized to an average particle size of about 3 microns.

Fine powder (average particle size: 3 microns) obtained as described above as a functional ore for increasing negative ions
In a small amount of solvent (DMF), gradually increase the amount of the solvent while kneading with a disperser such as a ladle machine so that the ore and the solvent become equal in amount, and the fine powder of the ore is uniformly dispersed. Make a blended solution.

Next, this blended liquid is mixed with a polyurethane resin, a pigment and a solvent and further kneaded by a disper.
In this way, from the synthetic resin in which ore fine powder is uniformly dispersed,
A thin film of 5 to 100 microns is formed by a known thin film forming method such as a gravure coating method and a coating method. Then, the thin film health material of the present invention is obtained by bonding the thin film to the surface of a sheet-shaped base material which has been formed in advance according to the use.

As described above, in the present invention, the synthetic resin containing the fine powder of the artificial functional ore which increases the negative ions is used.
By molding into a thin film of 0 micron or less, fine powder particles of about 3 micron can be located relatively close to the surface of the resin, so that the ratio of negative ion inhibition by the resin can be made relatively small. Many negative ions can be emitted into the air. Moreover, by attaching it to a sheet-shaped base material, the necessary mechanical strength such as tensile strength can be obtained according to the application, so synthetic leather for insoles, furniture such as chairs, or accordion curtains, wallpaper, etc. It can be easily used as a product, and can emit negative ions that are desirable for health in the room.

Further, a sheet-like health material can be produced without inhibiting the increase of negative ions by adhering the synthetic resin, in which fine powder is uniformly dispersed, in a dot shape on the surface of the sheet-like substrate. That is, the synthetic resin is attached in the form of a large number of dots on the surface of a sheet-shaped substrate by a known processing method such as a gravure coater or a printing method. Since the surface area is increased by depositing the synthetic resin in a dot shape as described above, the proportion of fine powdery ore located on the surface is increased, and the increase of negative ions is improved.

The thin film 4 of μ is a dot-like surface layer in which a polyurethane resin is adhered to the surface of the thin film 3 in the form of dots of 120 mesh in an amount of 20 g / m ² .

[0014]

[Table 1]

Table 1 shows a method of manufacturing a sheet-like health material having the structure shown in FIG. 1 by changing the amount of fine powder mixed with the polyurethane resin forming the thin film 3 within a range of 0 to 20 g / m ^2. The amount of the fine powder mixed in the polyurethane resin forming the surface layer 4 was changed in the range of 0 to 8 g / m ² , and the negative ion strength (unit: ion / cc) was measured by an ion tester for each product and the result was obtained. It is a representation. As can be seen from Table 2, by adding a larger amount of artificial functional ore to the polyurethane resin forming the dot-shaped surface layer, the negative ion strength can be more effectively increased with a small amount.

As described above, according to the method for producing a sheet-shaped health material of the present invention, the sheet-shaped base material can be used as various health materials without inhibiting the increase of negative ions due to the artificial functional ore. There is a beneficial effect that can be done.
