Description

The present invention collects fine particles of Shimajiri mudstone (sea silt) produced only in the southern part of the main island of Okinawa by agglomeration, precipitation, and collection by separating and removing impurities and contaminants accumulated on the cathode side. The present invention relates to a method, a cosmetic, a haptic agent, a cleaning agent based on adsorptiveness, and the like, and a method for producing the same, using the static adsorptive properties of the clay mineral fine particles.

The product of the present invention is derived from marlstone (sea silt) distributed in the southern part of Okinawa Main Island. As described in Japanese Patent Application Laid-Open No. 2002-29924 previously proposed by the inventor of the present invention, the chemical composition is It consists of mica (48-56%), smectite (28-35%), chlorite and kaolinite (14-18%).

However, as described in Japanese Patent Application No. 2003-278656, when a clay pack using mudstone fine particles was applied to the skin while paying attention to the unique characteristics of the mudstone fine particles, while conducting various tests A voltage of several tens of mV was also detected between the surface of the pack and the adjacent skin. In cases of tendonitis or arthritis, symptoms that make it difficult to stretch and flex due to strong pain appear, but when this clay pack is applied to abnormally existing fingers or joints, the pain immediately fades and the fingers and joints extend. And the effect of being able to bend appeared. In this way, the clay of Shimajiri mudstone (the dialect name is Kucha) distributed in the southern part of the main island of Okinawa generates relatively strong static electricity. It was confirmed that there was an effect.
JP2002-29924 Japanese Patent Application 2003-278656

Due to the strong adsorptivity as described above, it adheres to the dirt components of the skin and dirt of the teeth, and has a cleaning effect that can be easily removed by washing with water. This adsorption mechanism is related to the high cation exchange capacity of the mineral fine particles, and it has been found that it naturally has a relatively strong charge. Therefore, we will realize a production method that enhances the features of the product by selectively collecting particles with clear charge from the clay mineral particles by electrification with an electrophoresis device.

The technical problem of the present invention is to realize such fine clay particles that can effectively exhibit the characteristics of the fine particles of sea silt, paying attention to such problems. It was also found that applying a pack made of this clay to the skin produced a voltage, causing current in the body to flow and showing an analgesic effect instantaneously. A new type of analgesic poultice has been developed by adding an electrolyte as a device to extract the characteristics of static electricity generation more effectively. In addition, the clay particles themselves are negatively charged, which not only has the effect of reducing the solution, but it can also be seen that the solution exhibits stronger reductivity by applying voltage and current. The range has been expanded.

The main clay minerals that make up this tuff are all known as minerals with high cation exchange capacity (CEC), and the surface of these minerals has a negative charge. In addition to manufacturing cosmetics and cosmetics, toothpaste, precious metals, detergents for kitchens, etc., and methods for producing adsorbent cleaning agents, and the effect of electrostatic treatment on deep body tissues using the charge of the clay minerals This includes the manufacture of pharmaceuticals that have the characteristics, tissue preservation materials that extend the survival time of cells in the isolated organs, cell culture media, reduced water, and their production, as well as products that have the property of generating anions and their production methods. Included in the invention.

The technical problem of the present invention is solved by the following means. Claim 1 utilizes the fact that the surface of fine particles of marlstone sea silt, which is a special soil in the southern region of Okinawa main island, has a negative charge,
By placing a cathode on the upper side and an anode on the lower side in an aqueous suspension of sea silt in a sedimentation tank, and applying a voltage between the cathode and the anode by electrophoresis, a negative current is passed. Agglomerated and precipitated fine particles that are charged to the anode side by electrophoresis with direct current electricity, then taken out and dried,
When draining the upper layer of water in the settling tank from the upper drainage port, separating and removing the portion combined with foreign substances such as organic substances accumulated by migration on the cathode side,
By setting the sampling port at a desired water level in the water suspension of the raw material sea silt placed in the raw material collecting settling tank provided in the preceding stage of the settling tank, the upper particle size floating without being settled The smaller fine particles of the above are transferred from the sampling port to the subsequent precipitation tank, and foreign matters such as organic matter are floated on the liquid surface,
Is a method for producing ultrafine clay minerals.
An aqueous suspension of siltstone constituent mineral particles, which are considered to be special soil in the southern part of the main island of Okinawa, is prepared. Fine particles of approximately 5 microns or less are filtered and separated by a filter, and then the fine particles are separated by precipitation. Use a method in accordance with the Minamata method for collecting potato. However, since charged ultrafine particles have a slow sedimentation rate in water and take a long working time, and use a filter press to leak from the filter, the purpose is to shorten the working time and collect fine particles. If a method is applied to apply an electric current by electrophoresis to increase the agglomeration and settling speed of fine particles, the negatively charged fine particles are agglomerated and precipitated on the anode side and then taken out. Can be dried.
In addition, when draining the upper layer water in the settling tank from the upper drainage port, the portion combined with foreign substances such as organic substances accumulated by electrophoresis on the cathode side is separated and discharged to remove, depending on the particle size. Separation and collection by particle size by separation and purification, and separation and removal of the portion combined with foreign substances are possible.
Furthermore, in order to separate and collect the desired particle size from the sea silt rock, a plurality of sedimentation tanks are provided, and a sampling port is set at a desired water level in the raw material collection sedimentation tank in the previous stage, and the collected sea silt is collected. Transfer to the subsequent settling tank. When an aqueous suspension containing sea silt of various particle sizes is placed in a raw material collection sedimentation tank and left to stand, the sedimentation rate is faster for particles with a larger particle size, and sedimentation is more difficult for particles with a smaller particle size. Therefore, if a sampling port is installed in the lower part of the raw material collection sedimentation tank, particles with a large particle size can be collected, and if a sampling port is installed near the water surface, particles with a smaller particle size are collected and the next stage is collected. It can be transferred to a settling tank.
In the raw material collection / precipitation tank in the previous stage, foreign substances such as organic substances are floated on the liquid surface, so there is no fear of being sucked into the collection port.

A second aspect of the present invention is the method for producing an ultrafine clay mineral according to the first aspect, wherein the sampling port is movable up and down.
A sampling port 8 that can move up and down as shown by an arrow in FIG. 9 is installed, and a water suspension of the raw material sea siltstone is placed in the raw material collection and precipitation tank 1a. In order to collect fine particles having a smaller particle size, when the collection port 8 is moved upward, the fine particles on the upper side that are floating without being settled are pumped up, and the raw material injection pipe 4a of the chain line is used. It is transferred to the subsequent settling tank 1 where adsorption aggregation and electrophoretic separation and removal are performed by electrophoresis. It should be noted that foreign matters such as organic substances floating on the liquid surface L are not sucked into the sampling port 8, which is convenient.

Claim 3 is produced using the ultrafine clay mineral produced by the method according to claim 1 or 2 which exhibits electroadsorption due to the electrochemical characteristics of the negatively charged fine particles of sea silt. A cleaning agent for use in toothpaste, skin pack cosmetics, skin cleansing gel, hair shampoo or kitchen appliance, precious metal or mirror polish.
As described above, the negatively charged fine particles of sea silt have a property of cleaning the surface contaminated with organic substances and the like, and therefore, toothpaste and other detergents can be realized using the fine particles of sea silt. As a surface cleaning agent, it is possible not only to brush teeth but also to exert a strong effect on water around kitchens, appliance cleaning agents, precious metals and other mirror polishing. In addition, the deodorizing effect is exhibited simultaneously with the cleaning.
In the conventional cosmetics, in the case of clay-based cosmetics and cosmetic packs applied to the skin, nutritional effects such as minerals contained in the clay on the epidermal cells, hair, and skin tissue that are directly touched are expected. On the other hand, the material of the present invention uses a fine particle portion (particle size) that has not been applied so far in the present invention, so that the physical adsorption action and the effect of charging can be used for cosmetics, toothpaste, and kitchen use. Detergents can be manufactured. For example, it can also be applied to cosmetics for skin packs such as the face, skin cleansing gel, shampoo for hair and the like.

According to a fourth aspect of the present invention, the sea silt ultrafine clay mineral produced by the method according to the first or second aspect of the present invention is used as a raw material for western paper, and an ion generation effect is obtained by charging by providing a clayey layer. It is a wallpaper characterized by making it possible to use the properties it has.
Fine clay particles are indispensable for the production of western paper, but the fine mineral particles of sea silt of the present invention generate static electricity, and this feature is used to produce paper that releases anions. I can do it. When this paper is used for wallpaper in a room, the deodorizing effect and air purification can be achieved by the negative ion generation effect. When the suspension of sea silt particles is electrophoresed, it becomes basic at about pH 10 due to its reducibility and has the property of becoming alkaline ionized water, which is considered good for health. Can be applied.

Claim 5 is applied to the skin surface in a state where water is added to the ultra fine clay mineral of sea silt produced by the method of claim 1 or claim 2 to form a viscous clay, and aluminum, zinc, gold Cell activators, analgesic poultices, skin pack cosmetics, skin cleansings that use the property that, when covered with a metal such as silver, the metal side is negatively charged and generates a voltage on the opposite side Gel or hair shampoo.
As described above, when the analgesic effect is increased with a compress, the effect of increasing the voltage is increased about 10 times by covering the clay with an aluminum foil or a film or cloth with aluminum vapor deposition. The same applies not only to compresses but also to cell metabolism activators in tissue culture and the like. By using the negative charge on the surface of the sea silt fine particles, various skin preparations and cosmetics can be produced.

Claim 6 is a method in which water is added to the ultra fine clay mineral of sea silt produced by the method of claim 1 or claim 2 to form a viscous clay, and an electrolyte comprising salt or potassium chloride is added to the water. 6. The cell activator, analgesic poultice, skin pack cosmetic, skin cleansing gel or hair shampoo according to claim 5, wherein the ion exchange property and conductivity are enhanced.
As described above, by adding an electrolyte such as a salt to increase the conductivity, the electrical effect is further increased. Therefore, it is particularly effective when a plaster or the like is produced using a base having adhesiveness.

In order to produce detergents, building materials, cell activators, skin patches, etc. as described above, it is necessary to efficiently mass-produce ultra fine particles of sea silt. The sedimentation rate is slow and it takes a long working time, and when a filter press is used, leakage occurs from the filter.
Therefore, as described in claim 1, for the purpose of shortening the working time and collecting the fine particles, it is possible to solve the problem by increasing the aggregation and sedimentation rate of the sea silt fine particles by applying a voltage by electrophoresis and applying a current. At this time, the portion coupled with the foreign matter accumulated by electrophoresis on the upper cathode side is drained from the upper drainage port and separated and removed, so that purification is performed.
Furthermore, in order to collect a desired particle size, the time can be further shortened by using a plurality of precipitation tanks and using a difference in sedimentation speed depending on the particle size and electrophoresis. At this time, if a sampling port is set in the upper part of the raw material collection and sedimentation tank in the previous stage, particles having a smaller particle size can be collected, and if a sampling port is set in the lower part, particles having a larger particle size can be collected. . Therefore, any particle size can be collected according to the installation height of the collection port.
In the raw material collection / precipitation tank in the previous stage, foreign substances such as organic substances are floated on the liquid surface, so there is no fear of being sucked into the collection port.

If the sampling port 8 of FIG. 9 is movable up and down as in claim 2, the sampling port 8 is moved upward to pump up the finer particles having a smaller particle size on the upper side, and the subsequent sedimentation tank 1 Can be transported to.

As in claim 3, the negatively charged fine particles of sea silt can be used to produce a toothpaste and a kitchen appliance detergent that can utilize the physical adsorption action and the effect of the charge, such as cosmetics for skin packs such as the face, It can also be applied to skin cleansing gels and shampoos for hair.
In addition, when a material provided with a clayey layer containing fine particles of sea silt is used as wallpaper for a room or the like as in claim 4, a deodorizing effect and air purification can be achieved by the negative ion generation effect.

As in claim 5, the effect of increasing the voltage by covering the clay with aluminum foil or aluminum-deposited film or cloth is increased about 10 times. Effective for metabolic activators. Furthermore, by utilizing the negative charge on the surface of the sea silt fine particles, various skin preparations and cosmetics can be produced. Further, as described in claim 6, by adding salts and a moisturizing agent to increase the conductivity, the effect is further enhanced, so that it is effective for a plaster containing an adhesive base.

Skin packs developed as cosmetics have stronger cleaning effects and acne disappearance than expected, and the main mechanism of action is the physicochemical adsorption of clay minerals due to ultrafine particles. This is due to the ion exchange property due to static electricity existing on the crystal surface of the fine particles, which is an unprecedented effect used for this purpose.

Therefore, the application products can be developed more widely by drawing out this effect more strongly. There has never been a salve that exhibits a strong analgesic effect without the use of analgesics, and there is a possibility that it will be a safe and excellent product without any harmful effects. The composition of painkiller poultices currently on the market is a product produced by mixing resin-based materials with adhesive plasters, analgesics, etc., and therefore has no commonality with this. Although it has been used effectively for painful affected areas such as tenosynovitis and osteoarthritis, this product clearly has an excellent analgesic effect that is quicker than conventional compresses. Admitted.

Next, an embodiment of how the charged clay mineral particles and the method for producing the same according to the present invention are actualized will be described. The main body of this mudstone is clay mineral, and fine particles less than 5 microns occupy about 60 to 80%. Used as a purification method. However, these clay particles have a lot of extremely fine submicron-level fine particles and tend to leak from the filter cloth of the filter press. Therefore, as a conventional technique, a method of acidifying with hydrochloric acid or the like and aggregating it is used.

However, in the case of the present invention, as a technique for precipitating the fine particles, a method has been developed in which charged mineral fine particles are agglomerated and precipitated by applying electricity by electrophoresis without adding an acid. At this time, since the solution is reduced, it exhibits basicity having surface activity. FIG. 1 to FIG. 4 show the state of clay fine particle precipitation experiments by electrophoresis. First, as shown in FIG. 1, the clay suspension is put in two transparent containers. FIG. 1 shows the situation before the start of energization. When 1 hour has passed since the start of energization, as shown in FIG. 2, in the state of a clay suspension in which precipitation has been promoted by the action of electrophoresis, mineral fine particles are precipitated at the bottom, and the entire amount corresponding to that amount Transparency has increased.

FIG. 3 shows the state of sedimentation of fine clay particles 3 hours after the start of electrophoresis, and the overall transparency further increases, and the amount of sediment at the bottom increases accordingly. When the transparency increases and the amount of airborne particles is reduced, electrophoresis is stopped. FIG. 4 shows the state of sedimentation of the clay suspension 20 hours after the termination of electrophoresis, and it is completely transparent as a whole. As described above, when a clay suspension is aggregated and precipitated by electrophoresis, even fine particles of 5 microns or less can be aggregated and precipitated in a relatively short time.

In the conventional cosmetics, in the case of clay-based cosmetics and cosmetic packs applied to the skin, nutritional effects such as minerals contained in the clay on the epidermal cells, hair, and skin tissue that are directly touched are expected. On the other hand, the material of the present invention uses a fine particle portion (particle size) that has not been applied so far in the present invention, so that the physical adsorption action and the effect of charging can be used for cosmetics, toothpaste, and kitchen use. Detergents can be manufactured. For example, it can also be applied to cosmetics for skin packs such as the face, skin cleansing gel, shampoo for hair and the like.

Furthermore, plasters such as poultices can exert physiological effects by applying voltage from the skin surface to skin appendages, peripheral nerves, muscle tissues, bone and joint tissues, and organs in body cavities located deeper than the skin. It is characterized by the fact that it can utilize effects through mechanisms such as cell activity activation action, analgesic action due to the effect on sensory nerve working current, and cell metabolism enhancement. FIG. 5 and FIG. 6 verify the state of electricity flowing from the skin while confirming such an action.

That is, after applying clay agglomerated and precipitated by electrophoresis as shown in FIGS. 1 to 4 to the skin of the back of the hand, the voltmeter in the state where the electrodes are stacked as shown in FIGS. It can be confirmed that a voltage is generated from the clay side toward the palm side electrode. Stainless steel was used for both electrodes. FIG. 5 shows a voltage of 20 mV when clay is applied to the back of the hand to a thickness of about 1 to 2 mm. On the other hand, FIG. 6 shows the case where the thickness of the back clay was approximately doubled (4-5 mm), and the voltage rose to 60 mV, approximately three times.

Electrophoresis of a suspension of sea silt (muffstone) particles becomes basic at about pH 10 due to its reducibility, and has the property of becoming alkaline ionized water that is considered good for health. Applicable to manufacturing equipment. In addition, a certain amount of clay (kaolin, etc.) is generally used in the paper manufacturing process, but when these sea silt fine particles are used as additive clay, building materials such as wallpaper that have an ion generation effect due to charge. Can be manufactured. In other words, fine clay particles are indispensable as a raw material for Western paper, but the fine mineral particles of the sea silt of the present invention generate static electricity. Can be manufactured. When this paper is used for wallpaper in a room, the deodorizing effect and air purification can be achieved by the negative ion generation effect.

The present invention does not simply use the tuff (sea silt, kucha) distributed in the southern part of the main island of Okinawa as it is, but agglomerates fine particles with high cation exchange properties by electrophoresis, and collects and collects them. Products that take advantage of their characteristics. This property is in the area where there has never been a folklore tradition or a scientific announcement as a characteristic of tuff, and no commercialization has been made by applying this characteristic.

That is, a manufacturing method of cosmetics and packs using Okinawa's tuff (prior application: Japanese Patent Application 2000-21)
3718, Japanese Patent Application Laid-Open No. 2002-29924, Japanese Patent Application No. 2003-278656), and a new application method based on new electrochemical knowledge was developed.

Toothpaste is also a type of abrasive, but based on standard commercially available toothpaste, a toothpaste in which fine particles of sea silt (mudstone) according to the present invention are mixed with this toothpaste is manufactured and further compared. As a target control group, four types of toothpaste made by adding 1% of graphite and 1% of powder of Bincho charcoal were subjected to a comparative test of adsorptivity.

The test method was compared with an experiment in which these toothpastes were only applied to a hard-to-drop stain such as a mirror in the bathroom, and polishing was not performed. FIG. 7 compares the cleaning effect of adsorption by applying toothpaste to a cloudy mirror in the bathroom in the state where the above four types of toothpaste adsorption experiments are being conducted. (1) is a state where it is applied to a dirty mirror in a bathroom, (2) is a state where the surface is not rubbed at all, and it is washed away by showering, (3) is re-condensed with indoor steam after washing. Each state is shown. The types of tooth brushing are those in which standard (standard), marine silt (sea silt), graphite (graphite powder), and charcoal (Bincho charcoal powder) are mixed with 1% standard from the left. As a result of the test, the marine silt, that is, the toothpaste containing sea silt, proved that the dirt was removed by adsorption most clearly, and the best results were shown.

In addition, a standard commercial toothpaste, a toothpaste made by adding 1% sea silt (mudstone) to the same toothpaste, a toothpaste made by adding 1% graphite, and 1% powder from Bincho charcoal For the four types of toothpastes made in this way, ink adsorption experiments were conducted. As shown in Fig. 8, the experimental method is to prepare the same amount of the same sumi in each test tube, add the same amount of the above four types of toothpaste, mix, and clear the liquid by adsorption. Compared. First, as shown in (1), prepare an equal amount of ink liquor in four test tubes, and then add and mix an equal amount of toothpaste as in (2). To. From the left, the types of toothpaste added were standard (standard), marine silt (sea silt), graphite (graphite powder), and charcoal (Bincho charcoal powder) mixed in 1% standard. In this way, the state after 5 hours is (3). As a result, as apparent from (3), marine silt showed the highest transparency. That is, it was clear that the one with marine silt (sea silt) was the fastest and strong adsorbent to ink and was precipitated to be transparent.

FIGS. 1 to 4 show the state of sedimentation experiment of clay fine particles by electrophoresis, while FIG. 9 is a longitudinal sectional view of a funnel type sedimentation tank provided with an electrophoresis apparatus. This apparatus is for mass production. A cathode 2 is arranged on the upper side of the sedimentation tank 1 and an anode 3 is arranged on the lower side thereof, and wired to a DC power source. A water suspension of sea siltstone as a raw material is injected into the sedimentation tank 1 at the bottom of the tank through a raw material injection pipe 4. This raw material is used after filtering and separating fine particles of 5 microns or less with a filter. In this state, when a voltage is applied between the cathode 2 and the anode 3 by electrophoresis, a negatively charged fine particle is agglomerated on the anode 3 side due to the adsorption action due to static electricity and the sedimentation speed is increased. Speed up. The ultrafine particles purified in this way are discharged to the product take-out port 6 by the bottom MONO pump 5. The upper layer water is drained from the drainage port 7, and at this time, a portion combined with foreign substances such as organic substances accumulated by migration on the cathode side is also separated and discharged and removed.

For fine particle raw materials of 5 microns or less, the difference in sedimentation speed depending on the particle size can be used in addition to filtration and fractionation using a filter. A precipitation tank 1a for collecting raw materials is provided in the preceding stage of the precipitation tank 1 in FIG. 9, and a sampling port 8 that can be moved up and down as shown by an arrow is installed, and a water suspension of raw material sea silt rock in the precipitation tank 1a. Put in. In order to collect fine particles having a smaller particle size, when the collection port 8 is moved upward, the fine particles on the upper side that are floating without being settled are pumped up, and the raw material injection pipe 4a of the chain line is used. It is transferred to the subsequent settling tank 1 where adsorption aggregation and electrophoretic separation and removal are performed by electrophoresis. It should be noted that foreign matters such as organic substances floating on the liquid surface L are not sucked into the sampling port 8, which is convenient.

FIG. 10 is a flowchart showing the process of separating and refining fine clay particles from Shimajiri mudstone using the electrophoresis funnel settling tank of FIG. Prepare a water suspension after washing several times of the sea siltstone clay, which is considered as special soil in the area. Next, in step S2, filtration is performed using a 200 mesh filter, and fine clay particles of 10 to 20 microns or less are used. In step S3, the fine particles are pumped into the funnel settling tank of FIG.

Then, since the clay with large particles precipitates when left standing, the clay with large particles of about 5 microns or more is taken out from the lower part after allowing to settle for about 1 hour as in step S4. Then, with the fine particle clay of less than about 5 microns remaining, a voltage is applied between the electrodes 2 and 3 of the electrophoresis apparatus as in step S5. As a result, fine particles of less than about 5 microns are electrically agglomerated and attracted to the anode 3 to precipitate. Therefore, aggregation and precipitation by electrophoresis of ultrafine particles of clay are effectively performed in a short time. As in Step S6, the next day, when taken out from the lower part with the MONO pump 5, and dried in Step S7, it is used as a raw material for analgesic poultice, electrostatic treatment for deep body tissues, production of reduced water, anion generation paper, etc. It becomes possible.

As described above, according to the present invention, the raw material of sea silt particles can be refined and produced by effectively agglomerating and precipitating clay ultrafine particles by electrophoresis. It can be used for the manufacture of drugs, antistatic drugs for deep body tissues, the production of reduced water, anion generation paper, and the like.

This is a situation of a clay suspension in which precipitation is promoted by the action 1 hour after the start of electrophoresis. It is a sedimentation state of clay fine particles 3 hours after the start of electrophoresis. This is the sedimentation state of the clay suspension 20 hours after the electrophoresis was stopped. This is a case where the viscosity thickness is 1 to 2 mm in the state of voltage measurement between the clay surface applied to the back of the hand and the palm side. In the measurement of FIG. 5, the viscosity thickness is 4 to 5 mm. It seems that the adsorption experiment is done by brushing teeth on the mirror surface in the bathroom. It seems that various toothpastes are mixed in a test tube containing the ink-dissolved water to test adsorption and purification. It is a longitudinal cross-sectional view of the funnel type precipitation tank which installed the electrophoresis apparatus. It is a flowchart of the process of fractionating and refining fine clay particles using a funnel-shaped sedimentation tank.
