Detailed Description of the Invention

[0001]

TECHNICAL FIELD The present invention relates to the maintenance and treatment of health obtained by a highly efficient infrared ray, far infrared ray emission function and negative ion generation function possessed by a specific metal carbide compound, and a heat generation function in the presence of water molecules. , A functional patch material effective for beauty.

[0002]

2. Description of the Related Art It has been widely known that a specific metal carbide compound has an excellent function as described above, and a fiber, a molded article or a patch containing the metal carbide compound utilizing this function is widely known. Agents have been used as health equipment, medical equipment, cosmetics, and cosmetic products. However, the excellent function of the metal carbide compound as a material has not been sufficiently exhibited in any of the product forms.

[0003]

SUMMARY OF THE INVENTION It is an object of the present invention to find out a product form and a manufacturing method thereof which can highly exhibit the excellent function of a metal carbide compound as a material.

[0004]

[Means for Solving the Problems] As a result of various studies conducted by the present inventors, in order for the metal carbide compound to exert its excellent function at a high level, the metal carbide compound should be as large as possible from the product structure. The present invention was completed by preparing a patch having an excellent function by discovering that it is in a state of having the above-mentioned condition and the presence of an appropriate amount of water.

By dispersing the metal carbide compound close to the fine particle units, the surface area of the metal carbide material is increased, and the radiation dose of infrared rays, far infrared rays and the emission amount of negative ions are increased. Furthermore, the presence of a suitable amount of water promotes the release of negative ions from the metal carbide compound, facilitates its migration into the skin and body, and increases the calorific value found in the carbide compound. Since the excellent functions of the metal carbide compounds are highly exerted, the blood circulation promotion and active oxygen suppression effects, which are said to be the basis of improvement of health maintenance, physical abnormalities, lifestyle-related diseases, etc., increase. . This is effective in eliminating fatigue, muscle aches, stiff shoulders, low back pain, and the like, and is also effective in improving various medical lifestyle-related diseases and skin abnormalities, and in cosmetics.

[0006]

BEST MODE FOR CARRYING OUT THE INVENTION That is, the surface of a metal carbide compound is often very highly hydrophobic in nature, and in the production of a patch material, the metal carbide compound is sufficiently dispersed to have a large material surface area. It was difficult to prepare and apply a coating solution having a high solid content. On the other hand, by coating and drying the coating agent containing the acrylic acid copolymer as set forth in claim 3, the above-mentioned difficulties are solved and the coating layer exhibits the function of the present invention. It is now possible to have suitable moisture permeability and equilibrium water content. Further, the adhesive coating solution according to claim 4 was applied thereon and dried to complete an excellent functional patch material.

The acrylic ester resin for forming the second layer according to claim 3 has an anionic monomer of 0.3 to 1.0 in which acrylic acid and maleic acid are used alone or in combination.
It is necessary to copolymerize 2% to 10% by weight of N, N-diethylaminoethyl acrylate N-vinyl-2-hyrrolidone as a cationic monomer, either alone or in combination. When the copolymerization ratio of the anionic monomer is 1.0% by weight or more, the copolymerization ratio of the cationic monomer is 10% or more.
When it is more than 0.1%, secondary aggregation of dispersed fine particles of the metal carbide compound occurs, which is not preferable. When the amount of the anionic monomer was 0.3% by weight or less and the amount of the cationic monomer was 2% or less, it was not possible to obtain the second layer in which the dispersion of the carbide was good at a high metal carbide compound concentration. Also, the mixing ratio of acrylic acid and maleic acid, and NN-diethylaminoethyl acrylate and N
The compounding ratio of -vinyl-2-pyrrolidone is not particularly limited, but it is also preferable that the compounding ratio is equal. The acrylic acid ester monomer is preferably selected from ethyl ester, butyl ester and 2-ethylhexyl ester, and the ratio of the amount of copolymerization of these acrylic acid ester monomers is not particularly limited. .

As the metal carbide compound, aluminum carbide, uranium carbide, zirconium carbide, strontium carbide, tungsten carbide, titanium carbide, niobium carbide, vanadium carbide, barium carbide, and molybdenum carbide have excellent functions, and one or more of them can be used. Can be used in combination. Claim 3 with respect to 100 parts by weight of the metal carbide compound.
30 parts by weight to 10 parts by weight of acrylic acid-based resin in terms of solid content
Compounding is carried out at a ratio of 0 part by weight, a proper amount of a solvent such as ethyl acetate and toluene is added, and a coating solution is produced by a high speed stirrer such as a disper and a ball mill. It was possible to obtain a coating solution dispersed in the fine particle state of the metal carbide compound.

Since the compounded solution according to claim 3 obtained by the present invention has excellent compatibility with other resins, acrylic ester resins of various compositions, SBR rubbers, isoprene rubbers, butyl rubbers. It may be used as a mixture with various rubbers such as, for example, within a limit of mutual solubility within a range not impairing the effect of the present invention.

The acrylic ester-based pressure-sensitive adhesive according to claim 4, which forms the third layer, is obtained by copolymerizing 2 to 10% by weight of N-vinyl-2-pyrrolidone to form the second layer and human skin. In addition to having a great improvement in the adhesive force to, it is possible to have moisture permeability and equilibrium water content suitable for the subject of the present invention.

Examples of the polyfunctional isocyanate compound include diisocyanates such as tolylene diisocyanate, diphenylmethane disocyanate, xylene diisocyanate and hexamethylene diisocyanate, trimethylolpropane tolylene isocyanate, and polyfunctional aromatic polyisocyanates. If 0.1 to 5% of polyfunctional isocyanate is mixed with acrylic ester resin, cohesive strength can be increased without impairing the surface adhesive strength of the second layer and the third layer, and it is harsh when used during exercise. It can be used under various usage conditions.

Examples of the polyalkylene glycol include polypropylene glycol and polybutylene glycol. Among them, polypropylene glycol having a molecular weight of 400 & 6000 is preferable. If the acrylic ester adhesive in the second layer and the third layer is mixed in an amount of 5 to 35% in terms of pure content, moisture permeability is improved without impairing the water resistance characteristics of each layer, and the water content of each layer is constantly maintained. Properly maintained, it has become possible to maintain excellent features for a long time.

When producing a coating agent for forming each layer, an activator, an antiseptic, an antioxidant, and an antifoaming agent which are usually used in the production of the coating agent are used within the range of not impairing the function of the product of the present invention. It is possible to add agents and the like within a range that does not impair the performance.

The coating amount of the second layer and the third layer is as follows.
In order for the patch according to the present invention to exert a sufficient function, the second
The layer is preferably 50 g / m ² or more in terms of solid, and the third layer is preferably 30 g / m ² or more. ,
