Abstract

PURPOSE:To obtain the subject sheet or tape capable of making a microcurrent flow through the skin by application thereto and readily and lightly applying the static electrotherapy. CONSTITUTION:This tacky sheet 10 is obtained by forming a tacky agent layer containing many hydrophilic granular materials 13, prepared by forming a substance having the hydrophilicity such as a shell material, e.g. a grain or a nut into a granular shape and two kinds of electrically conductive granular materials 17 and 18, having different ionization tendencies and dispersed therein on one surface of a substrate 11 and respectively exposing the hydrophilic granular materials 13 and the two kinds of electrically conductive granular materials 17 and 18 to at least one surface of the tacky agent layer. When the sheet 10 is applied to the skin, liquid substances such as sweat and moisture of the skin are absorbed from the exposed hydrophilic granular materials 13 to conduct the two kinds of the electrically conductive granular materials 17 and 18. Thereby, a microcurrent flows from the contact surface of the electrically conductive granular materials 17 having a lower ionization tendency with the skin through the skin, to the contact surface of the electrically conductive granular materials 18 having the higher ionization tendency with the skin.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION The present invention, when applied to the skin, causes a minute electric current to flow through the skin due to moisture caused by sweating or bathing, which causes cells in an electric field (electrical space field) to be generated by the minute electric current. The present invention relates to a dispersion sheet or tape that can generate a small electric current that is activated to promote electrostatic treatment or health, an adhesive sheet or tape that generates a small electric current, and a resin film sheet or tape that generates an electric current. In the present invention, hydrophilicity is a general term including water absorption and water permeability.

2. Description of the Related Art Generally, the electrostatic treatment method is to discharge static electricity on a mat-like rug with an electrostatic treatment device to artificially create an electric field, and then apply the mat to a part of the body or sit on the mat. It puts the body in the electric field and activates the function of the body.

The above-mentioned electrostatic treatment method will be described in more detail. Cells of the human body function to absorb, excrete and secrete substances. Each time the resting potential (the potential when the cell is not active) changes, an action potential is generated, and it immediately returns to the normal resting potential. The function of nerves is also related to action potentials. For example, if you give instructions from the brain to your hands, feet,
When it is transmitted to the periphery such as eyes and mouth, or when the sense of the periphery is transmitted to the brain, it changes from resting potential to action potential in nerve cells and is transmitted. Therefore, it is considered that when an external potential is applied to cells of the human body, the cells are affected by the external potential and activated. This therapy is said to be effective in treating hypertension, autonomic imbalance, stiff shoulders, asthma and the like.

On the other hand, a pressure-sensitive adhesive sheet or tape is a non-woven fabric, a breathable base material such as cloth, or a surface base material such as an amorphous vinyl chloride film or a polyurethane film which can expand and contract according to the movement of the human body. The drug (hereinafter, referred to as “adhesive” in the present specification, including not only the drug itself but also the drug mixed or applied to the adhesive) is simply and uniformly applied. These adhesive sheets or tapes are coated with or mixed with adhesive bandages, bandages, surgical skin coatings, skin adhesives, disinfectants that are effective from the skin of the human body, and anti-inflammatory agents. Some of them are used as cloths and the like, and these pressure-sensitive adhesive sheets or tapes are attached to an affected area where trauma or inflammation is caused, and analgesia or treatment is performed by the medicinal effect of the drug in the pressure-sensitive adhesive.

An adhesive sheet or tape with a magnet has been developed as a treatment method or a health promotion method using the adhesive sheet or tape. The adhesive sheet or tape with a magnet is the adhesive agent of the adhesive sheet or tape. A permanent magnet is attached to the surface, and this is attached to the skin to improve blood circulation in the skin by the magnetic field generated from the permanent magnet.

[0006]

The electrostatic therapy device used in the conventional electrostatic therapy is inconvenient to carry, and the patient must put a mat-like rug on the body during treatment. There was a problem of being bound by location and time.

For the above reasons, the conventional electrostatic therapy has a problem that the treatment time is limited because the patient is restrained in time.

Further, there is a problem that the rug such as the electrotherapy device and the mat is not easy to handle.

Further, the conventional adhesive sheet or tape simply protects the affected area or treats it by the medicinal effect of the drug in the adhesive, and an adhesive sheet or tape with a magnet using the adhesive sheet or tape has been developed. However, it does not have the electrotherapy function intended by the present invention.

The present invention was developed in order to solve the above problems. When it is applied to the skin, an electric current flows through the skin to generate an electric field, which activates the cells of the human body. It is an object of the present invention to provide a dispersion sheet or tape, an adhesive sheet or tape, and a resin film sheet or tape which can be treated and promote health, and which can be subjected to electrotherapy that does not cause inflammation such as whitening, rash and eczema. .

[0011]

In order to achieve the above object, in the dispersion sheet or tape of the present invention, a large number of hydrophilic granules 13 formed by granulating a hydrophilic substance and an ionization tendency. A large number of two kinds of conductive particles 17 and 18 formed by forming two kinds of different conductive materials
Is dispersed.

Further, in the pressure-sensitive adhesive sheet or tape of the present invention, a large number of hydrophilic particles 13 having hydrophilicity in the dispersion sheet or tape and two kinds of conductive particles 17, 18 having different ionization tendency are dispersed. The pressure-sensitive adhesive layer is formed on one surface of the base material.

Further, in the resin film sheet or tape of the present invention, a large number of hydrophilic particles 13 having hydrophilicity in the dispersion sheet or tape and two kinds of conductive particles 17 and 18 having different ionization tendency are used as the resin. It is dispersed in the film.

The adhesive sheet or tape and the resin film sheet or tape are made of two kinds of conductive particles 17 and 18 having different ionization tendency from the hydrophilic particles.
Is exposed on at least one surface of the pressure-sensitive adhesive layer or the resin film, and the hydrophilic particles 13 intervene such that water absorbed by the exposed hydrophilic particles conducts two kinds of conductive particles 17 and 18. is there.

Further, the adhesive sheet or tape,
Also, the resin film sheet or tape has a structure in which both surfaces of the pressure-sensitive adhesive layer or the resin film are cross-linked with one or a plurality of hydrophilic particles 13 to expose the pressure-sensitive adhesive layer 12 or both surfaces of the resin film, and the hydrophilic particles. A gap 14 penetrating in the thickness direction of the pressure-sensitive adhesive layer or the resin film may be formed at the interface between the pressure-sensitive adhesive layer or the resin film 13 and the pressure-sensitive adhesive layer 12, and the pressure-sensitive adhesive layer 12 may be formed on one surface of the breathable substrate.

In the pressure-sensitive adhesive sheet or tape of the present invention, the pressure-sensitive adhesive layer 12 or the resin film in which a large number of hydrophilic particles 13 formed by granularly forming a hydrophilic substance are dispersed has a different ionization tendency. Two kinds of conductors are polymerized on one surface of a breathable base material having a large number of ventilation holes woven so as not to short-circuit with each other, and the pressure-sensitive adhesive layer or the resin film is used for the other breathable base material through the ventilation holes. It is exposed on the surface.

The hydrophilic granules 13 are formed by granulating hydrophilic shells such as grains and nuts.

Further, the pressure-sensitive adhesive layer or the resin film can be formed with a thickness equal to or smaller than the size of the hydrophilic particles 13 and the conductive particles 17, 18.

The pressure-sensitive adhesive layer or resin is formed by forming the one or more hydrophilic particles 13 with a particle size of 17 to 200 μ and the conductive particles 17 and 18 with a particle size or a needle length of 15 to 300 μ. The film can be formed to have a total thickness of 20 to 80 μ.

[0020]

When the pressure-sensitive adhesive sheet 10 having the above-mentioned structure is attached to the skin of a human body, the hydrophilic particles 13 expose liquid on the skin such as sweat and water to one side of the pressure-sensitive adhesive layer in contact with the skin. It is absorbed and the liquid content is absorbed by one or more hydrophilic granules 13.
Absorbs and swells with water, and then the liquid content of the hydrophilic granules 13 becomes 2
Since the conductive particles 17 and 18 of the seeds are electrically connected to each other, a chemical reaction similar to that of a so-called battery occurs between the conductive particles 17 and 18 of two kinds having different ionization tendencies through the liquid content of the hydrophilic particles 13. , The conductive particle 17 having a smaller ionization tendency is the positive electrode (+
The conductive particle 18 having the larger ionization tendency becomes the negative electrode (negative electrode). On the other hand, since the two kinds of conductive particles 17 and 18 come into contact with the skin, which is a conductor, an electric current flows in the skin from the positive electrode conductive particle 17 toward the negative electrode conductive particle 18. This electric current is so small that no one can feel it. Therefore, a person does not have to be aware that a minute current is flowing,
The cells in the electric field of low current are activated, and so-called electrostatic treatment is performed.

When the pressure-sensitive adhesive sheet 10 is formed by cross-linking both surfaces of the pressure-sensitive adhesive layer with one or a plurality of hydrophilic particles 13 and forming this pressure-sensitive adhesive layer on one surface of the air-permeable substrate 11, ionization is performed in the same manner as described above. A minute current flows in the skin between the two kinds of conductive particles 17 and 18 having different tendencies, and the liquid content of the skin absorbed by the hydrophilic particles 13 exposed on one surface of the adhesive layer in contact with the skin is: After being absorbed by the one or more hydrophilic granules 13 and swollen in water, it diffuses to the outside air through the breathable base material 11 to prevent skin whitening, inflammation such as eczema and the like. In addition, sterilization or sterilization action can be obtained by the generated minute electric current. Furthermore, since the gap 14 between one or a plurality of hydrophilic particles 13 cross-linked between both surfaces of the pressure-sensitive adhesive layer and the pressure-sensitive adhesive 12 serves as a ventilation hole in the thickness direction of the pressure-sensitive adhesive layer, the pressure-sensitive adhesive sheet 10 is attached to the skin. However, there is less interference with skin breathing.

Further, unlike the above-mentioned adhesive sheet 10, the resin film sheet 30 does not have an adhesive layer, but when the resin film sheet 30 is wrapped around the skin and fixed with a stopper, the skin will sweat. The hydrophilic granules 13 in the film absorb the sweat and swell with water to conduct electricity between the two kinds of conductive granules 17 and 18, and the conductive granules 1 as described above.
A minute current flows from 7 to the conductive particles 18 in the skin.
When the resin film sheet 30 is immersed in water, the hydrophilic particles 13 in the film swell and expand, closing the gap 14 and stopping the water permeability of the resin film sheet 30.

EXAMPLES In the following, in this example, a dispersion sheet, an adhesive sheet, a resin film sheet, and a method for producing the same will be described. The dispersion tape, the adhesive tape, the resin film tape, and a method for producing the same will be described above. The sheet is processed into a tape shape, so the description is omitted.

[Dispersion Sheet and Adhesive Sheet] The dispersion sheet and the adhesive sheet will be described with reference to FIG.

Reference numeral 10 denotes a pressure-sensitive adhesive sheet, which includes a large number of hydrophilic particles 13 formed by granularly forming a substance having hydrophilicity in a rubber-based or acrylic-based pressure-sensitive adhesive 12 and two kinds of different ionization tendency. A large number of conductive particles 17 and 18 are mixed and dispersed to form a mixed dispersion solution, and the mixed dispersion solution is used as the base material 11.
The pressure-sensitive adhesive layer was formed by coating (solid content coating) over the entire area of one surface so as to have a total thickness of 20 to 80 μm without fluidization. However, the total thickness of the adhesive layer is 10 to 2
00μ is preferably 20 to 80μ.

On the surface of the pressure-sensitive adhesive layer of the pressure-sensitive adhesive sheet 10, a release paper 15 made of a plastic film or paper coated with a release agent on one side or both sides is attached.

The base material 11 includes the air-permeable base material 11a or the non-air-permeable base material 11b. The air-permeable base material 11a is preferable in order to prevent inflammation such as whitening, eczema, rash, etc. 11b is also acceptable.

As the breathable substrate 11a, a non-woven fabric,
It includes a woven cloth, a PVC film, a urethane film, an olefin film, a rubber film, and other porous base materials, other permeable base materials, and a base material in which a large number of through holes are formed in the above material. .

The adhesive 12 is not limited to rubber type or acrylic type, but silicone type, polyvinyl type, polyurethane type,
A polyester type etc. can be used.

The conductive particles 17 and 18 are formed by granulating two kinds of conductive materials having different ionization tendencies, respectively.
In this embodiment, copper powder is used as the conductive particles 17 having a low ionization tendency, and aluminum powder is used as the conductive particles 18 having a high ionization tendency.

As shown in FIG. 1, the conductive particles 17 and 18 are exposed on both surfaces of the pressure-sensitive adhesive layer or on at least one surface of the both surfaces on the side where the pressure-sensitive adhesive layer is attached to the skin. The shape, particle size or needle length of the conductive particles 17, 18 are not particularly limited as long as they are within the size range described later. Therefore, the conductive particles 17 and 18 having different shapes, particle sizes or needle lengths can be mixed in the adhesive layer. In this case, as shown in FIG.
8 is one in which one conductive particle 17 or 18 exists in the adhesive layer independently, and a plurality of conductive particles 17 or 1
8 are connected to each other and exposed so as to crosslink between both surfaces of the pressure-sensitive adhesive layer, and one conductive granular material 17 or 18 is exposed on both surfaces of the pressure-sensitive adhesive layer. It exists in the agent layer. That is, when the conductive particles 17 and 18 having different shapes, particle sizes or needle lengths are mixed,
When the particle diameter or needle length of each conductive particle 17, 18 is less than the thickness of the adhesive layer, two or more conductive particles 17, 1
When 8 is connected or polymerized, it is appropriately exposed from the pressure-sensitive adhesive layer, and when the particle diameter or needle length of the conductive particles 17, 18 exceeds the thickness of the pressure-sensitive adhesive layer, the self-weight and the pressure-sensitive adhesive layer In the coating step, the conductive particles 17 and 18 are inclined and tumbled according to their shapes, so that they are appropriately exposed without excessively protruding from the adhesive layer.

Conductive particles 17 or 18 buried in the adhesive layer
Due to the water absorption of the hydrophilic granules 13, the minute current generated by is conducted to the conductive granules 17 or 18 exposed on the surface via the hydrophilic granules 13. As a result, even a small current generated by the conductive particles 17, 18 buried in the adhesive layer can be conducted to the skin. However, in order to increase the electric capacity, prolong the life of electricity generation, and further ensure that each particle of the conductive particles 17 or 18 is exposed to both surfaces of the adhesive layer or the surface in contact with the skin, Conductive particles 17
Or the particle size of each of 18 is the same as the thickness of the adhesive layer,
It is preferable to form it larger than this.

The shape of the conductive particles 17 or 18 is desirable if the finely pulverized powder is dispersible with the adhesive.
A filler, a string, a band, or another shape may be used.

The particle diameter or needle length of the conductive particles 17 or 18 is in the range of 10 to 400 μ, preferably 15 to 300 μ.

The hydrophilic granules 13 are grain shells of rice, wheat, peanuts and the like (rice and wheat are chaffs), or dried shells of hydrophilic nuts and the like having a particle size of 10 to 300 μm.
It is preferably formed in a granular shape with a size of 17 to 200 μm, and the component of the hydrophilic granules 13 composed of the shell has a hydrophilic group such as starch type, cellulose type, tannin type, polysaccharide type, lignin type and the like. Therefore, it is highly hydrophilic.

As with the conductive particles 17 and 18, a large number of hydrophilic particles 13 dispersed in the pressure-sensitive adhesive layer do not have to have a uniform particle size as long as they are within the above-mentioned particle size range. . Therefore, as shown in FIG. 1, one hydrophilic granule 13 alone is dispersed in the pressure-sensitive adhesive layer, and a plurality of hydrophilic granules 13 are connected to each other so that both surfaces of the pressure-sensitive adhesive layer are crosslinked. The hydrophilic particles 13 are present in the adhesive layer in various forms, such as one exposed on both sides and one hydrophilic particle 13 exposed on both sides of the adhesive layer.

However, the hydrophilic particles 13 are the conductive particles 1.
Similar to Nos. 7 and 18, at least one of the two surfaces of the pressure-sensitive adhesive layer is exposed on the side where the pressure-sensitive adhesive layer is attached to the skin, and the liquid content such as sweat and water absorbed from the exposed hydrophilic granules 2 is 2
The conductive particles 17 and 18 of the kind are interposed so as to be electrically connected. That is, since a minute gap 14 is formed at the interface between the hydrophilic particles 13 and the pressure-sensitive adhesive 12, one or a plurality of hydrophilic particles 13 do not necessarily bridge between the two kinds of conductive particles 17 and 18. Even if it is not, the hydrophilic particles 13 are swollen by the liquid and block the gap 14, or the liquid is so hydrophilic that the liquid penetrates into the gap 14 and conducts between the two kinds of conductive particles 17 and 18. It suffices that the granules 13 are present in the adhesive 12.

When the adhesive sheet 10 is attached to the skin, the base material 11 is formed of the breathable base material 11a in order to prevent inflammation such as whitening, eczema, and rash.
It is desirable that the hydrophilic granules 13 be crosslinked on both sides of the pressure-sensitive adhesive layer with one or a plurality of hydrophilic granules 13. In this case, the one or more hydrophilic granules 13 cross-linked between both surfaces of the pressure-sensitive adhesive layer provide water permeability, while the hydrophilic granules 13 and the pressure-sensitive adhesive 12 are provided.
A small gap 1 that penetrates in the thickness direction of the adhesive layer at the interface
4, the gap 14 provides air permeability between both surfaces of the adhesive layer.

In order to ensure that the hydrophilic particles 13 are cross-linked and exposed between both surfaces of the pressure-sensitive adhesive layer and to interpose the two kinds of conductive particles 17 and 18 in the pressure-sensitive adhesive 12, the pressure-sensitive adhesive is used. 12, the hydrophilic granules 13, and the conductive particles 17, 18 are mixed in a ratio of 100 parts by weight of the adhesive to the conductive particles 17 or 18.
2 to 20 and hydrophilic granules 13 to 5 to 40 parts by weight.

The volume ratio of the conductive particles 17 and 18 is 1: 1.

The total thickness of the pressure-sensitive adhesive sheet 10 of the above embodiment is limited to about 200 μ, but 20 to 80 μ is preferable from the viewpoint of material yield.

The pressure-sensitive adhesive layer of the pressure-sensitive adhesive sheet 10 of the above embodiment can be used as a dispersion sheet 9 alone as a product.

For example, a pressure-sensitive adhesive layer similar to the pressure-sensitive adhesive sheet 10 is applied to the release surface of the release paper 15 to obtain a product, the dispersion sheet 9 is attached to the affected area, and then the release paper 15 is peeled off.
Then, the surface of the dispersion sheet can be used by covering it with a cloth or bandage.

Therefore, the dispersion sheet 9 of the present application is a generic term for a sheet in which the large number of hydrophilic particles 13 and the two kinds of conductive particles 17 and 18 having different ionization tendencies are dispersed, and the large number of hydrophilic particles. When the particles 13 and the two kinds of conductive particles 17 and 18 having different ionization tendency are dispersed in the pressure-sensitive adhesive 12 such as a drug, the pressure-sensitive adhesive sheet does not easily cause inflammation even when attached to the skin, and the hydrophilicity Grain 1
3 and two kinds of conductive particles 17 and 1 having different ionization tendency
When 8 is dispersed in a resin film, it becomes a resin film sheet and is a very widely applicable sheet.

[Operation of Adhesive Sheet] Next, the adhesive sheet 1
The action of 0 will be described.

After peeling the release paper 15 from the pressure-sensitive adhesive sheet 10 of FIG. 1, the surface of the pressure-sensitive adhesive layer of the pressure-sensitive adhesive sheet 10 is attached to the skin of a human body as shown in FIG. Since it is always moistened with sweat, the hydrophilic granules 13 exposed on one surface of the pressure-sensitive adhesive layer in contact with the skin absorb the liquid content (sweat) of the skin, and the hydrophilic granules 13 in the pressure-sensitive adhesive layer are entirely wetted with liquid. Be swollen. Therefore, the liquid swollen hydrophilic granules 13 fill the gaps 14 or the gaps 14 that are slightly left are filled with liquids, and these liquids are copper of the conductive granules 17 having a smaller ionization tendency. Conduction is established between the powder and the aluminum powder of the conductive particles 18 having the larger ionization tendency. Then, the conductive granules 17 (Cu) and the conductive granules 1 having different ionization tendencies via the liquid particles in the hydrophilic granules 13 and the gaps 14
A chemical reaction similar to that of a so-called battery occurs between 8 (Al). That is, as shown in FIG. 2, the conductive particle 17 (Cu) having a smaller ionization tendency is the positive electrode (+ pole), and the conductive particle 18 (Al) having a larger ionization tendency is the negative electrode (− pole),
The liquid content in the hydrophilic granules 13 and the gap 14 becomes an electrolyte,
A battery reaction occurs in which the positive electrode (+ electrode) of the so-called conductive particles 17 (Cu) receives electrons and the negative electrode (− electrode) of the conductive particles 18 (Al) emits electrons.

Therefore, the two types of conductive particles 17, 18
Are exposed on the surface of the pressure-sensitive adhesive layer, so that they contact the skin which is a conductor, and in this skin, the conductive particles 17 (Cu) whose electric current is more positive than that of the positive electrode Flows toward. The current at this time is so small that people do not feel it, so people do not have to be aware that the current is flowing,
The cells in the electric field of low current are activated and subjected to electrostatic therapy.

Further, the base material 11 is a breathable base material 11a,
In addition, the pressure-sensitive adhesive sheet 10 in which both surfaces of the pressure-sensitive adhesive layer are cross-linked with one or a plurality of hydrophilic granules 13 has the function of generating a slight electric current as described above, and at the same time, the one or more hydrophilic particles 13 are aforesaid. The liquid swelled in its entirety diffuses from the hydrophilic granules 13 exposed on the surface of the pressure-sensitive adhesive layer in contact with the air-permeable base material 11a to the outside air through the air-permeable base material 11a, and in addition, between both surfaces of the pressure-sensitive adhesive layer. One or a plurality of hydrophilic granules 13 cross-linked with the adhesive 1
Although the gap 14 between the two is closed by the swollen hydrophilic granules 13, the slightly remaining gap 14 serves as a ventilation hole in the thickness direction of the adhesive layer, so that the skin breathing is less obstructed, and thus the skin Is less likely to cause inflammation.

Further, the adhesive sheet 10 is actually pulled and attached to the skin, and the attached adhesive sheet 10
Is further pulled with the movement of the skin, the breathable base material 11a and the adhesive 12 of the adhesive sheet 10 are stretched, and as a result, the gap 14 between the interfaces of the adhesive 12 and the hydrophilic granules 13 is expanded, The spread of the gap 14 is partial and does not totally shut off the liquid component in the gap 14 that conducts between the two kinds of conductive particles 17 and 18 and the hydrophilic particle 13.

When the adhesive sheet 10 is adhered to the skin and exercised or when taking a bath, the gap 14 expanded as described above is filled with the liquid and a minute current is constantly generated. On the other hand, the liquid content filled in the gap 14 and the hydrophilic granules 13 is diffused to the outside air by the water permeability of the adhesive sheet 10, so that the skin is less likely to be inflamed.

[Other Adhesive Sheet] Next, an example of another adhesive sheet 10a will be described with reference to FIG. 4 while omitting the same parts as the adhesive sheet 10. Reference numeral 19 denotes a conductor base material, which is formed by weaving two kinds of linear conductors 27 and 28 having different ionization tendencies into a breathable base material having a through hole so as not to short-circuit with each other. For example, a copper wire is used as the conductor 27 having a low ionization tendency, and an aluminum wire is used as the conductor 28 having a high ionization tendency in one direction in parallel or alternately in every two or in an appropriate arrangement. Is.

As the conductor base material 19, a non-conductor such as plastic is used for the warp yarns and a copper wire (conductor 27) and an aluminum wire (conductor 28) are used for the weft yarns so as not to short-circuit, so that a non-woven fabric is obtained. It can be formed in a mesh shape having through holes.

In the adhesive sheet 10a, the conductive base material 19 is coated with a mixed solution in which a number of hydrophilic particles 13 are mixed and dispersed in the adhesive 12, and the hydrophilic particles 13 penetrate the conductive base material 19. It is introduced into the holes and exposed on the surface of the conductor substrate 19. The hydrophilic particles 13 in the adhesive 12 are
The liquid swelled liquid is interposed so as to establish electrical connection between the conductors 27 and 28 of the conductor substrate 19.

Unlike the dispersion of the conductive particles 17 and 18 of the pressure-sensitive adhesive sheet 10 described above, the pressure-sensitive adhesive sheet 10a systematically determines the intervals between the conductors 27 and 28, and also the hydrophilic particles inside the pressure-sensitive adhesive 12. By increasing the amount of 13, a large number of hydrophilic granules 13 can be surely brought into contact with each other and the conduction state between the conductors 27 and 28 can be made good, resulting in high efficiency.

[Manufacturing Method of Dispersion Sheet and Adhesive Sheet] Next, a manufacturing method of the dispersion sheet 9 and the adhesive sheet 10 will be described below with reference to FIG. (1) Grains of rice, wheat, peanuts or the like or dried shells of water-absorbing nuts or the like having a particle size of 17 to 2
A large number of hydrophilic granules 13 formed in a granular shape of 00 μ are immersed in water or alcohol. Then, since the composition of the hydrophilic granules 13 is mainly composed of hydrophilic pentosan, lignin, cellulose, ash (silica, etc.), the weight ratio of the hydrophilic granules 13 swells to 1.5 to 10 times in a normal state.

In this step, since the large number of hydrophilic particles 13 are immersed in water or alcohol, the hydrophilic particles 13 can be washed.

It should be noted that since shells such as rice husks and rice pearls and peanuts have fine spines and sharp-angled projections, only the spines and projections on the shell surface are heated by heating the shell surface. After incineration, the granules are pulverized, preferably finely pulverized to form hydrophilic granules 13.

(2) Next, an organic solvent such as toluene or hexane as the solvent-based adhesive 12, a large number of hydrophilic particles 13 swollen, copper powder as conductive particles 17 having a low ionization tendency, and ionization. Aluminum powder is mixed into the adhesive 12 as the conductive particles 18 having a large tendency to form a mixed solution in which the hydrophilic particles 13 and the conductive particles 17 and 18 are uniformly dispersed in the adhesive 12. At this time, the adhesive 12 is 1
2 to 20 parts by weight of the conductive particles 17 and 18 and 5 to 40 parts by weight of the hydrophilic particles 13 are mixed with 00 parts by weight.

The pressure-sensitive adhesive 12 is preferably a rubber-based, acrylic-based, silicone-based, polyvinyl-based, polyurethane-based, polyester-based pressure-sensitive adhesive, but is not particularly limited.

In the case of a thread-like fibrous material such as wood pulp or rayon yarn having water absorbability, when mixed with the pressure-sensitive adhesive 12, the thread-shaped fibrous material settles or forms a dumpling so that it is uniformly distributed in the pressure-sensitive adhesive 12. Although not dispersed, since the hydrophilic granules 13 are granular, they are uniformly mixed and dispersed in the adhesive 12,
The mixed state of the hydrophilic particles 13 and the pressure-sensitive adhesive 12 is very good.

The composition of the hydrophilic granules 13 is easily assimilated by being polymerized with the organic solvent, and is easily eluted. However, when the hydrophilic granules 13 are swollen as described above, the hydrophilic granules 13 are swelled.
Since the liquid cross-linking inside protects the composition of the hydrophilic granules 13 from being assimilated into the organic solvent of the adhesive 12, even if the hydrophilic granules 13 are mixed in the solvent-based adhesive 12, Grain 1
The water absorbency of 3 does not decrease. Therefore, it is preferable to use the liquid swollen hydrophilic granules 13 for the solvent-based pressure-sensitive adhesive 12 for the above reason, but the solvent-based adhesive 12 is not necessarily limited to the liquid swollen hydrophilic granules 13.

For the solventless adhesive 12 such as hot melt, preferably dried hydrophilic granules 13 can be used.

(3) The pressure-sensitive adhesive 12 of the above item (2) is formed on the roll-shaped one-sided or double-sided release paper 15 by various coating methods such as a doctor roll coater and a die coater.
Then, a mixed solution of the hydrophilic granules 13 and the conductive granules 17 and 18 is applied as a solid content in a uniform thickness of 20 to 80 μm.

At this time, a large number of hydrophilic particles 13 and conductive particles 17, 18 are exposed on both surfaces of the adhesive layer as shown in FIG. 1, and the hydrophilic particles 13 are electrically conductive by the absorbed liquid. The particles 17 and 18 are interposed so as to be electrically connected.

The dispersed state of the conductive particles 17 and 18 is uniform with the hydrophilic particles 13 with respect to the adhesive.

The dispersed state of the hydrophilic particles 13 in the adhesive layer is
One hydrophilic granule 13 is mixed in the adhesive 12, one hydrophilic granule 13 is independently exposed on both sides of the adhesive layer, or a plurality of hydrophilic granules 13 are on both sides of the adhesive layer. It is exposed on both sides of the adhesive layer in a row. In order to manufacture the dispersion sheet 10 having excellent water permeability, it is necessary to crosslink between both surfaces of the pressure-sensitive adhesive layer with one or more hydrophilic particles 13 to expose the hydrophilic particles 13 on both surfaces of the pressure-sensitive adhesive layer. Although it is desirable, if water permeability is not taken into consideration, it may be exposed on at least one side of the pressure-sensitive adhesive layer on which the pressure-sensitive adhesive layer is attached to the skin.

The dispersion state of the hydrophilic particles 13 in the pressure-sensitive adhesive layer varies depending on the size of the hydrophilic particles 13, the thickness of the pressure-sensitive adhesive layer, and the weight ratio of the hydrophilic particles 13 and the pressure-sensitive adhesive 12.

For example, the particle size of the hydrophilic granules 13 is from 17 to 20.
0μ, particle size of conductive particles 17, 18 or needle length 15 to 3
It is desirable to apply the pressure-sensitive adhesive layer so that the total thickness is 20 to 80 μm with respect to 00 μm. When the thickness is more than that, the exposed portions of the hydrophilic granules 13 and the conductive granules 17 and 18 on both surfaces of the adhesive 12 layer become small, or the exposed hydrophilic granules 13 and the conductive granules 17 and 18 become small. Therefore, the water absorption of the pressure-sensitive adhesive sheet 10 is reduced.

The release surface of the release paper 15 is preferably made of silicone, which has excellent releasability, but may be non-silicone if it has the desired releasability.

(4) Next, as shown in FIG. 2, the solvent-based pressure-sensitive adhesive 12 is passed through a dryer 23 and dried with hot air, and the solvent-free pressure-sensitive adhesive 12 such as hot melt is not shown. Cool it by passing it through a cooling device. At this time, the adhesive 12 is treated so as not to fluidize.

When the pressure-sensitive adhesive layers of the pressure-sensitive adhesive 12 and the hydrophilic particles 13 pass through the dryer 23, the boiling point of the organic solvent of the pressure-sensitive adhesive 12 is 60 ° C. Since the pressure-sensitive adhesive 12 rapidly shrinks to form a film, and the liquid content in the hydrophilic granules 13 evaporates at 100 ° C. thereafter, the pressure-sensitive adhesive 12 does not flow around the hydrophilic granules 13 and is hydrophilic. A minute gap 14 (FIG. 1) is formed at the interface between the particles 13 and the adhesive 12. When the hydrophilic particles 13 are exposed on both sides of the layer of the pressure-sensitive adhesive 12, the gap 14 is necessarily formed so as to penetrate in the thickness direction of the pressure-sensitive adhesive layer, thereby providing air permeability of the pressure-sensitive adhesive layer.

The pressure-sensitive adhesive layer in this step is the so-called dispersion sheet 9 described above.

(5) Next, the dried pressure-sensitive adhesive layer on the release paper 15 is bonded and transferred to the substrate 11 between the rolls 24 and 25 to form the pressure-sensitive adhesive sheet 10 having a cross section shown in FIG.

[Other Manufacturing Method of Pressure-Sensitive Adhesive Sheet] In the manufacturing process of the pressure-sensitive adhesive sheet 10 described above, a pressure-sensitive adhesive layer is formed on the release paper 15, and this pressure-sensitive adhesive layer is transferred to the breathable substrate 11a. However, the adhesive 12 and the mixed solution of the hydrophilic granules 13 and the conductive granules 17 and 18 are directly applied to the air-permeable base material 11a in a solid content to form the adhesive sheet 10, and the adhesive 12 layer of the adhesive sheet 10 is formed. The release paper 15 may be attached to the.

[Manufacturing Method of Adhesive Sheet of FIG. 4] A manufacturing method of the adhesive sheet of FIG. 4 will be described with reference to FIG.

A large number of hydrophilic particles 1 swollen with an organic solvent such as toluene and hexane as the solvent-based adhesive 12
3 is mixed in the adhesive 12, and the hydrophilic granules 13 become the adhesive 12
Make a mixed solution that is uniformly dispersed inside.

Then, the conductor 27 having a small ionization tendency
As a conductor base material 19 formed by weaving a copper wire and an aluminum wire as a conductor 28 having a high ionization tendency into a non-woven fabric so as not to short-circuit every other one in parallel or every two wires in one direction. A roll-shaped one-sided or double-sided release paper 15 is polymerized, and a conductive base material 19 is coated with a mixed solution of the pressure-sensitive adhesive 12 and the hydrophilic granules 20 to 20 to 20 by various coating methods such as a doctor roll coater and a die coater. The solid content is applied with a uniform thickness of 80μ.

Others are the same as the manufacturing method of the pressure-sensitive adhesive sheet 10 described above.

[Resin Film Sheet] Next, the resin film sheet 30 will be described with reference to FIG. 3 while omitting the same parts as those of the pressure-sensitive adhesive sheet 10 described above. Unlike the adhesive sheet 10 described above, the resin film sheet 30 does not have an adhesive layer, so the resin film sheet 30 is applied to the skin and fixed with another stopper or an adhesive tape before use.

A resin film 32 is made of plastic such as vinyl chloride or polyurethane, or rubber type resin. As shown in FIG. 3, the resin film sheet 30 includes a large number of hydrophilic particles 13 having hydrophilicity in the resin film 32.
And two kinds of conductive particles 17 and 18 having different ionization tendencies
The hydrophilic particles 13 and the conductive particles 17, 18 are dispersed in the same manner as the hydrophilic particles 13 and the conductive particles 17, 18 in the pressure-sensitive adhesive layer of the pressure-sensitive adhesive sheet 10 described above. is there. For example, a large number of hydrophilic granules 13 in which one hydrophilic granule 13 is dispersed alone in the resin film 32,
There are various types such as one in which a plurality of hydrophilic particles 13 are connected to each other and exposed so as to crosslink between both surfaces of the resin film 32, one particle is exposed in both surfaces of the resin film 32, and the like. In addition, the conductive particles 17 and 18 are exposed on both surfaces of the resin film 32 or at least one surface of the both surfaces on the side where the resin film 32 is attached to the skin, and one conductive particle 17 or 18 is independently formed. Those scattered in the resin film 32, a plurality of conductive particles 17 or 1
8 are connected to each other and exposed so as to crosslink between both surfaces of the resin film 32, and one conductive particle 17 or 18 is exposed to both surfaces of the resin film 32.

Further, at the interface between the hydrophilic particles 13 and the pressure sensitive adhesive 12, which are in a state in which both surfaces of the resin film 32 are cross-linked by one or a plurality of hydrophilic particles 13, similar to the gap 14 of the pressure sensitive adhesive sheet 10 described above. In addition, a minute gap 34 forming a vent hole is formed between both surfaces of the resin film 32.

When the resin film 32 is a non-crystalline plastic film such as vinyl chloride or polyurethane, the resin film sheet 30 is rich in water resistance, so that it does not become brittle against water, It becomes a stretchable film.

[Operation of Resin Film Sheet] Therefore, when the resin film sheet 30 is applied to the skin and fixed with another stopper or an adhesive tape, the hydrophilic granules 13 exposed on one surface of the resin film 32 are removed from the skin. A liquid (sweat) is absorbed, and the one or a plurality of hydrophilic particles 13 are swollen into the liquid to conduct the two kinds of conductive particles 17 and 18 having different ionization tendencies to each other, so that a slight current flows in the skin to a positive pole. From the conductive particles 17 of No. 1 to the negative conductive particles 18. (It acts in the same manner as the hydrophilic granules 13 and the two kinds of conductive granules 17 and 18 in the adhesive layer of the adhesive sheet 10 when the adhesive sheet 10 is attached to the skin.) Also, both surfaces of the resin film 32. A resin fill sheet 30 in which one or more hydrophilic particles 13 are crosslinked
The liquid content in the hydrophilic particles 13 and the gaps 34 diverges from the hydrophilic particles 13 exposed on the other surface of the resin film 32 to the outside air, and in addition, the gaps 34 form ventilation holes in the thickness direction of the resin film 32. Therefore, it becomes highly hydrophilic. That is, the hydrophilic particles 13 in the resin film sheet 30 have a water absorbing function in the normal state of being exposed to the outside air,
Deaeration is performed in the gap 34. However, when the resin film sheet 30 gets wet with rain or is immersed in water, the hydrophilic particles 13 in the film swell and expand, so that the gap 34
To block the water permeation of the resin film sheet 30, that is, a so-called water stop function. Therefore, the resin film sheet 30 is a hydrophilic film sheet in the air, but is a water resistant film sheet in water, and is a very useful resin film sheet for performing electrostatic treatment.

Further, the resin film sheet of the present application is shown in FIG.
Of the pressure-sensitive adhesive sheet, and a large number of hydrophilic particles 13 are interposed in the resin film.
To penetrate into the through hole of the conductor base material 19
It is also possible to interpose between the conductors 27 and 28 of the conductor substrate 19 so that they are exposed to the surface of and the liquid particles swelling the hydrophilic particles 13 are electrically connected.

[Method for producing resin film sheet] Next,
The method of manufacturing the resin film sheet 30 will be described by omitting the same parts as those of the pressure-sensitive adhesive sheet 10 described above.

The raw material of the resin film sheet 30 is a plastic such as vinyl chloride or polyurethane or a rubber type resin, and a casting method, a T-die method such as an extrusion method, which is known as a film forming method of the resin film sheet 30, There is no limitation as long as it is a processing method for forming a film having a uniform thickness, such as a calendar roll method.

When the resin film sheet 30 is manufactured by a solvent type roll coater, a solvent type polymer is used as a binder, and when the resin film sheet 30 is manufactured by a solventless hot melt coater, a heat slack polymer is used as a binder.
The binder may be urethane type, acrylic type, polyvinyl type, rubber type, or the like.

Then, 5 to 40 parts by weight of hydrophilic particles with respect to 100 parts by weight of the binder and resin, copper powder as the conductive particles 17 having a low ionization tendency, and aluminum powder 2 as the conductive particles 18 having a high ionization tendency are used. 20 parts by weight are mixed and dispersed to form a mixed solution. When the binder is a solvent-type polymer, it is preferable to use the liquid swollen hydrophilic granules 13 in order to protect the hydrophilic granules 13 with liquid for the same reason as in the case of the pressure-sensitive adhesive sheet described above. When the binder is a solventless type heat-slow polymer, it is not limited thereto, but preferably dried hydrophilic granules 13 are used. A film is formed from this mixed solution by, for example, a roll coater as shown in FIG. 2 or an extruder or casting method by a known extrusion method (not shown) to obtain a resin film sheet 30. This resin film sheet 30 is a stretchable non-crystalline film having water resistance in which a large number of hydrophilic particles 13 are evenly and finely scattered in the film, and hydrophilic particles per unit area of 1 cm 2 of the film. The number of the bodies 13 depends on the clearance of the coater head and the mixing ratio of the binder and the hydrophilic particles 13.

For example, with respect to 100 parts by weight of a binder of a urethane-based or polyurethane-based solvent-based polymer, 40 parts by weight of the hydrophilic particles 13 and 2 parts by weight of an isocyanate group,
20 parts by weight of toluene is mixed, and this mixed solution is put into a known roll coater, and the knife clearance is adjusted so that flow resistance does not occur in the hydrophilic granules 13 of the mixed solution. Then, the mixed solution is cast coated on the release surface of the release paper 15. The film thickness of the resin film sheet 30 after drying is the same as the pressure-sensitive adhesive sheet 10 described above, so that the hydrophilic granules 13 and the conductive granules 17 and 18 are exposed on both sides of the film so as to have a particle size of 17 ~ 200μ,
Particle diameter of conductive particles 17, 18 or needle length 15 to 300 μ
On the other hand, a film thickness of 20 to 80 μ is desirable, but the film thickness is not limited to this value and may be 10 to 200 μ.

When the resin film sheet 30 obtained as described above is attached to the skin, a slight electric current flows between the two kinds of conductive particles 17 and 18 in the skin like the pressure-sensitive adhesive sheet 10 described above, so that the water resistance is improved. It is rich in water, does not become brittle with water, and has the elasticity of the film.
It has a minute gap 34 of about 50 μm.

Since the present invention is constructed as described above, it has the following effects.

(1) The dispersion sheet or tape, the pressure-sensitive adhesive sheet or tape, and the resin film sheet or tape have different ionization tendency from a large number of hydrophilic particles formed by granularly forming a hydrophilic substance. Since a large number of two kinds of conductive particles formed by forming two kinds of electric conductors in a granular form are dispersed, by attaching these tapes or sheets to the skin, the two kinds of conductive particles exposed on the surface of the tape or sheet are exposed. Since the conductive particles come into contact with the skin and the liquid content such as skin sweat and water absorbed from the hydrophilic particles conducts between the two conductive particles, the skin between the two conductive particles is slightly affected. An electric current was passed, and the skin was able to be subjected to electrostatic treatment.

(4) For the reason of the above item (1), since the sheet or tape of the present application is simply attached to the skin, a person can perform other things while receiving electrostatic treatment, and is bound by time. Do not receive

(5) By using a drug as the pressure-sensitive adhesive of the pressure-sensitive adhesive layer, the medicinal effect of the pressure-sensitive adhesive and electrostatic treatment are used together, so that the affected area can be effectively treated.

(6) The pressure-sensitive adhesive layer or the resin film is exposed on both sides of the pressure-sensitive adhesive layer or the resin film by cross-linking between both surfaces with one or more hydrophilic particles, and the hydrophilic particle and the pressure-sensitive adhesive or the resin are exposed. A gap penetrating in the thickness direction of the pressure-sensitive adhesive layer or the resin film is formed at the interface with the film, and since the pressure-sensitive adhesive layer is formed on one surface of the breathable substrate, it is less likely to cause inflammation even when attached to the skin, and It was possible to provide an electrotherapeutic sheet or tape having a sterilizing effect and a sterilizing effect with a small current.

(7) Due to the above-mentioned items (1) to (6), it is possible to provide a sheet or tape which can be applied to a very wide range.

Polymerized into a breathable base material having a large number of woven air vents, and since the pressure-sensitive adhesive layer or the resin film is exposed on the surface of the breathable base material through the vent holes,
It is possible to systematically determine the distance between the conductors, and increase the amount of hydrophilic particles in the adhesive or resin film to ensure that the hydrophilic particles are in contact with each other and to improve the conduction state between the conductors. As a result, an efficient sheet or tape could be provided.

(9) Since the pressure-sensitive adhesive layer or the resin film is formed with a thickness equal to or smaller than the size of the hydrophilic particles and the conductive particles, the pressure-sensitive adhesive layer or the resin film necessarily has a space between both surfaces. Crosslinking with hydrophilic granules, two conductive granules are exposed to both sides of the pressure-sensitive adhesive layer or resin film with one conductive granule, and these hydrophilic granules and conductive granules are adhesive. Because it is evenly distributed throughout the layer or resin film,
It was possible to provide a sheet or tape that is extremely water-permeable and that reliably generates a small current.
