Description

By providing the present invention on the surface of a base material such as paper, woven fabric, resin, metal, ceramics, or composite material, for example, bacteria, viruses, allergens, fungi, odorous substances, harmful substances, etc. are not irradiated with light. However, a method for producing a material having a bactericidal effect and a bactericidal effect, including an agent that can exert the same effect as the effect having continuously under light irradiation for a long period of time and can exert the effect in a short time. Regarding the manufacturing method of the product to have.

Conventionally, solid or liquid bactericides and deodorants are known. Most of the solid bactericides and deodorants are photocatalyst-related technologies that utilize the redox power of the photocatalyst. A normal photocatalyst can act for a long time because the photocatalyst itself is insoluble, but it works only in the presence of ultraviolet light and does not work in the dark. In addition, since the photocatalyst is a solid, it has a bactericidal and deodorizing effect when it comes into contact with bacteria, viruses, allergens, and organic substances that cause various odors, so it has a bactericidal or deodorizing effect on the surrounding environment. It takes time for the virus to be played. On the other hand, liquid bactericides or deodorants such as alcohol and hypochlorite usually act without the need for light and immediately exert an excellent bactericidal or deodorizing effect on the surrounding environment, but immediately. It only works for a short period of time because it vaporizes or evaporates. Moreover, many liquid fungicides in general are still toxic and therefore have the drawback of being environmentally friendly.

The conventional photocatalyst has a structure in which metallic silver is supported on a carrier made of titanium dioxide, for example, and bacteria, viruses, and allergens are generated by radicals generated through a redox reaction occurring on the surface of the photocatalyst in the presence of ultraviolet light. , It has a bactericidal effect and a deodorizing effect by decomposing organic substances that cause various odors. However, this redox reaction occurs only at the interface between silver and titanium dioxide in the photocatalyst, and the reaction is very weak under visible light, so it is considered that the photocatalyst is not useful in a dark environment. Was there.

On the other hand, Patent Documents 1 and 2 disclose inventions of an agent composed of silver particles and titanium dioxide particles, which have a bactericidal effect and a deodorizing effect even in the absence of light. This agent is different from the one in which the silver particles are supported on the surface of the titanium dioxide particles, and the silver particles and the titanium dioxide particles have a physical bond that makes them difficult to squeeze into each other.

Japanese Patent No. 5995100 Japanese Unexamined Patent Publication No. 2016-199560 Japanese Patent No. 5129897 Japanese Unexamined Patent Publication No. 2014-193433

According to the invention of the agent disclosed in Patent Documents 1 and 2, a predetermined bactericidal or deodorizing effect is exhibited even in a dark place where light does not exist, as a matter of course, in a place where light exists. The effect is excellent in that it can be maintained for a long period of time. However, since the agents disclosed in Patent Documents 1 and 2 are solid, they have a predetermined effect on the surrounding environment as compared with liquid bactericides or deodorants such as alcohol and hypochlorous acid. There is a problem that it takes time to play.

The above Patent Document 3 describes a copper compound having titanium oxide having a rutyl-type titanium oxide content of 50 mol% or more, and a monovalent copper compound and a divalent copper compound supported on the surface of the titanium oxide. The invention of a supported titanium oxide photocatalyst is disclosed. Further, Patent Document 4 discloses an invention of a visible light responsive hybrid photocatalyst obtained by mechanochemical reaction between copper ion-supported tungsten oxide particles and zeolite. However, the above-mentioned Patent Documents 3 and 4 do not show that silver particles or copper particles are provided, and moreover, the present invention relates to a photocatalyst that exhibits catalytic activity under room light, even if there is no light. It cannot exhibit catalytic activity.

The inventors have completed various studies on the conditions under which the time required to achieve a predetermined effect is shortened with respect to the agents disclosed in Patent Documents 1 and 2, and as a result, have completed the present invention. be. That is, an object of the present invention is an agent which has the same effect as the effect having continuously under light irradiation for a long period of time without light irradiation, and can exert those effects in a short time. Is to provide.

The above object of the present invention is achieved by the following configuration. That is, the agent having the same effect as that of the effect under the irradiation of light without the irradiation of light according to the first aspect of the present invention can be used.
Composite particles in which silver particles and titanium oxide or tungsten oxide particles are physically bonded,
(1) At least one kind of metal other than silver or metal oxide particles selected from copper, copper oxide, nickel, zinc, tungsten, tungsten oxide, molybdenum, and molybdenum oxide.
(2) Silver salt,
(3) Silver ion-supported zeolite,
With at least one material selected from and
It is characterized by including.

The agent of the first aspect of the present invention is not limited to composite particles in which silver particles and titanium oxide or tungsten oxide particles are physically bonded.
(1) At least one kind of metal other than silver or metal oxide particles selected from copper, copper oxide, nickel, zinc, tungsten, tungsten oxide, molybdenum, and molybdenum oxide.
(2) Silver salt,
(3) Silver ion-supported zeolite,
It also contains at least one material selected from.

Of these, composite particles in which silver particles and titanium oxide or tungsten oxide particles are physically bonded are known as agents having the same effect as that of light irradiation even without light irradiation. It is an ingredient that is present. The titanium oxide includes anatase type, rutile type, brookite type and the like, and may be any type of titanium oxide, or may be a mixture of two or more types.

Further, among the materials of (1), copper, nickel and zinc are all metals having a higher ionization tendency than silver, and therefore, when water is present in the surroundings, they are eluted as metal ions before silver. Similarly, a part of the surface of tungsten and molybdenum is oxidized in air to form tungsten oxide and molybdenum oxide, and when water is present in the surroundings, they are eluted as tungstic acid ion or molybdate ion. Similarly, in the presence of water around the copper oxide, a part of the surface is hydrated and eluted as copper ions.

The silver salt of (2) includes, for example, easily soluble silver salts such as silver nitrate, silver acetate, silver oxide, silver hydroxide, silver molybdenate, silver tungstate, silver carbonate, silver phosphate, silver sulfate, and chromium. It contains sparingly soluble silver salts such as acid salts, silver halides, and silver oxalate. In the case of easily soluble silver salt, when water is present in the surroundings, it immediately dissolves to generate silver ions, and in the case of poorly soluble silver salt, when water is present in the surroundings, the amount is determined by the solubility product of each compound. Silver ions (and anions) are formed. In either case, silver ions are generated in the presence of water in the surroundings, so the initial bactericidal effect can be improved. Since it produces silver ions, it has a high immediate effect. However, for example, silver nitrate is designated as a deleterious substance by the Poisonous and Deleterious Substances Control Law under Japanese law, and care must be taken such as using a very small amount. Further, the silver ion-supported zeolite (3) is well known as a silver-based inorganic antibacterial agent, and examples thereof include Zeomic (manufactured by Sinanen Zeomic Co., Ltd.) and Novalon (manufactured by Toagosei Co., Ltd.). In these silver ion-supported zeolites, silver ions are eluted when water is present in the surroundings.

The ions formed by at least one of the materials selected from the above (1) to (3) have an effect on the surroundings before the effect of the composite particles is exhibited, and as a result, the silver particles. Compared with the case of only composite particles in which titanium oxide or tungsten oxide particles are physically bonded to each other, a predetermined effect can be achieved in a short time. Further, at least one of the materials selected from the above (1) to (3) exerts a predetermined effect in the presence of moisture in the surroundings, but the first of the present invention is given even in a dry state. The above-mentioned action is caused by the water content in the material that comes into contact with the agent of the first aspect, for example, the water content contained inside a microorganism, a virus, or the like, and a predetermined effect can be obtained.

In addition, the effect of the agent of the first aspect of the present invention is the ion formed from the composite particle and at least one material selected from the above (1) to (3), and the composite particle generated concomitantly thereof. It is due to the radical generation in the above, but because of the slow ion formation rate, the effect can be obtained permanently for a long period of time, it is not biotoxic, and it does not form resistant bacteria. Become.

In the agent having the same effect as the effect under the irradiation of light without the irradiation of light of such an embodiment, the composite particles are bonded so that the silver particles and the titanium oxide or the tungsten oxide particles bite into each other. Is preferable. A state in which one of the silver particles and the titanium oxide or the tungsten oxide particles is difficult to squeeze into the other, or one and the other are difficult to squeeze into each other can also be expressed as mating. , Physical coupling includes these coupling modes.

If the silver particles and the titanium oxide or tungsten oxide particles have a physical bond that bites into each other, the light irradiation will be better even when there is no light irradiation, as a matter of course when there is light irradiation. It becomes possible to produce the same effect as the effect produced in a certain case.

Further, in the agent having the same effect as the effect having under the irradiation of light without the irradiation of light of such an embodiment, at least one of the selected materials is supported on the composite particles. In addition, it may be physically bonded to the composite particle.

If the silver particles in the composite particles and the titanium oxide or tungsten oxide particles are physically bonded, even if it is considered that at least one of the selected materials is supported on the surface of the composite particles. , Even if it is considered to be physically bonded, it is natural when there is light irradiation, and even when there is no light irradiation, it is similar to the effect that is produced when there is light irradiation. It can be effective.

Further, in the agent having the same effect as that of the agent having the same effect under the irradiation of light without the irradiation of light of the said aspect, the particle size of the silver particles and at least one selected material is 100 nm to 1 μm. Is preferable.

The particle size of the silver particles and at least one of the selected materials does not necessarily have a critical limit, but the above effect is well exhibited when the particle size is in the range of 100 nm to 1 μm. When the particle size of the silver particles and the selected at least one material is less than 100 nm, the dissolution rate of the silver particles and the selected at least one material becomes high in the presence of water in the surroundings. The time it takes for a given effect to be achieved is shortened, but the long-term effect is shortened, especially because at least one of the selected materials disappears prematurely. Further, when the particle size of the silver particles and at least one selected material exceeds 1 μm, the long-term effect is conversely good, but the time until the predetermined effect is initially obtained becomes long.

In the agent having the same effect as that of the effect under the irradiation of light without the irradiation of light of the said aspect, the content ratio of the silver particles in the composite particles is 0 with respect to 100 parts by mass of the titanium oxide or the tungsten oxide particles. It is preferably 1 to 5.0 parts by mass, and the content ratio of the selected at least one material is preferably 0.2 to 7 parts by mass with respect to 100 parts by mass of the titanium oxide or tungsten oxide particles.

When the content ratio of the silver particles in the composite particles is less than 0.1 parts by mass with respect to 100 parts by mass of the titanium oxide or tungsten oxide particles, the content of the silver particles is too small and the predetermined effect is difficult to be achieved. Further, even if the content ratio of the silver particles exceeds 5 parts by mass with respect to 100 parts by mass of titanium oxide, the effect is saturated and silver is expensive, so that it is wasted. The content ratio of the silver particles in the composite particles is 0.2 to 3 parts by mass with respect to 100 parts by mass of titanium oxide.

Further, when the content ratio of the selected at least one material is less than 0.2 parts by mass with respect to 100 parts by mass of the titanium oxide or tungsten oxide particles, the content ratio of the selected at least one material is too small. Therefore, the predetermined effect cannot be achieved. Further, even if the content ratio of the selected at least one kind of material exceeds 7 parts by mass with respect to 100 parts by mass of the titanium oxide or tungsten oxide particles, the effect is saturated. More preferably, the content ratio of at least one selected material is 2.5 to 4 parts by mass with respect to 100 parts by mass of titanium oxide or tungsten oxide particles.

In the agent having the same effect as that of the effect under the irradiation of light without the irradiation of light of the said aspect, the adsorbent is further contained in an amount of 5 to 50 parts by mass with respect to 100 parts by mass of the titanium oxide or tungsten oxide particles. The adsorbent is preferably hydroxyapatite.

Bacteria, fungi, viruses, allergens, odorous substances, regardless of the presence of the adsorbent, in the agent having the same effect as that of the agent having the same effect under the irradiation of light without the irradiation of the light of the aspect. And to have an effect on at least one of the harmful substances. In particular, when an adsorbent coexists, the adsorbent can adsorb bacteria, fungi, viruses, allergens, odorous substances, harmful substances, etc. (hereinafter, these may be collectively referred to as "objects to be treated"). , The object to be treated can be retained in the vicinity of the composite particles and at least one of the selected materials, and the above effects can be achieved satisfactorily. When hydroxyapatite is used as the adsorbent, the adsorption effect of the object to be treated is good, so that the effect can be more favorably exhibited. The effect on bacteria, fungi and viruses is also referred to as a bactericidal effect.

Although the content ratio of the adsorbent is not a critical limit, it is preferably 5 to 50 parts by mass with respect to 100 parts by mass of titanium oxide or tungsten oxide particles. If the content ratio of the adsorbent is less than 5 parts by mass with respect to 100 parts by mass of the titanium oxide or tungsten oxide particles, the effect of adding the adsorbent will not be exhibited. Further, when the content ratio of the adsorbent exceeds 50 parts by mass with respect to the titanium oxide or tungsten oxide particles, the content ratio of the composite particles and at least one selected material is relatively reduced, so that the above effect is reduced. do. When hydroxyapatite is used as the adsorbent, the content ratio of the adsorbent is more preferably 20 to 30 parts by mass with respect to 100 parts by mass of the titanium oxide or tungsten oxide particles.

[Preparation of Agent of Experimental Example 1]
In Experimental Example 1, first, composite particles physically bonded so that silver particles and titanium dioxide particles bite into each other were prepared according to the methods disclosed in Patent Documents 1 and 2. As the adsorbent, for example, zeolite, sepiolite, apatite, activated carbon and the like can be used, and other objects such as bacteria, fungi, viruses and allergens as well as unpleasant odorous substances and harmful substances are adsorbed and retained. Therefore, it can be used in the agent of the present invention. The present invention uses, among other things, hydroxyapatite, which acts as an adsorbent. The size of the hydroxyapatite particles in the present invention is particularly preferably 0.3 to 50 μm in order to secure a wider surface area and achieve good action. The mixing ratio of the ceramic bonded to the metal and the hyrodoxyapatite as an adsorbent is 100: 1 to 50 by mass, and has a desirable effect on, for example, bacteria, viruses, allergens, fungi, odorous substances or harmful substances. Therefore, it is particularly preferable that the ratio is 100: 1 to 30. The agent of the present invention can be prepared by mixing a ceramic bonded to a metal with an adsorbent.

For the ceramic bonded to the metal, (1) the thermal coupling method shown in FIG. 1, (2) the pressure coupling method shown in FIG. 2, and (3) the thermal / pressure coupling method shown in FIG. 3 are used. Can be prepared.

In the thermal bonding method (1), ceramic (TiO ₂ ) and metal (silver) particles are bonded through the hot zone shown in FIG. The purity of silver used is 80-99.9% and the purity of titanium dioxide is about 90-99%. In this process, a portion of the metal ingrown into the ceramic particles. As a result, the metal particles and the ceramic particles are bonded so that one of them is difficult to squeeze into the other, or one and the other are difficult to squeeze into each other (also referred to as fitting), that is, a physical bond is formed. Become. The temperature of the high temperature zone is substantially, for example, about 1000 ° C to 3200 ° C. By microscopic observation, it was confirmed that the obtained composite particles had a physical bond in which the silver particles and the titanium dioxide particles bite into each other.

Further, in the pressure coupling method (2), the ceramic and the metal are bonded through the use of the ball mill shown in FIG. The ball mill has very hard balls made of a material such as alumina or zirconium, the balls being, for example, about 0.1 mm, 0.004 mg. Further, in the heat / pressure coupling method of (3), as shown in FIG. 3, ceramic and metal particles can be bonded by applying heating and pressurization at the same time. Further, as a method for bonding the metal to the ceramic, other methods such as a high temperature roller and a high temperature ultrasonic crimping method may be used.

In Experimental Example 1, 0.5 g of silver particles having an average particle size of 300 nm, 80 g of anatase-type titanium dioxide particles having an average particle size of 250 nm, and hydroxyapatite having an average particle size of 1 μm (hereinafter, simply referred to as “Hy”) may be used. ) 20g was stirred and mixed in a laboratory ball mill using zirconia balls for 1 to 2 hours to prepare an agent consisting of silver particles-titanium dioxide particles-Hy particles of Experimental Example 1. The rotation speed of the ball mill at this time was such that the titanium dioxide particles were not pulverized and were rotated at a low speed so as to form a physical bond in which the silver particles and the titanium dioxide particles bite into each other. There may be places where silver particles and copper particles are in contact. Further, the time when hydroxyapatite is charged into the ball mill may be the same as the time when the silver particles and the titanium dioxide particles are charged, or a predetermined time after the time when the silver particles and the titanium dioxide particles are charged. You may. It is also possible to omit the adsorbent such as hydroxyapatite as described in Modification 3 described later.

The silver content in the obtained agent of Experimental Example 1 corresponds to 0.6 parts by mass with respect to 100 parts by mass of titanium dioxide, and the content of hydroxyapatite also corresponds to 25 parts by mass with respect to 100 parts by mass of titanium dioxide. do. 35 g of the obtained agent of Experimental Example 1 was dispersed in 65 mL of distilled water to prepare a stock solution of the agent of Experimental Example 1 having a solid content concentration of 35%.

[Preparation of Agent for Experimental Example 2]
In Experimental Example 2, 1.5 g of copper particles having an average particle size of 300 nm was added to 100.5 g of an agent composed of silver particles-titanium dioxide particles-Hy particles prepared in the same manner as in Experimental Example 1 to a ball mill. Stir or mix in for a few minutes. The silver particles-copper particles-titanium dioxide particles-Hy particles thus obtained have a physical bond so as to bite into the silver particles and the titanium dioxide particles, and copper is a titanium dioxide or hydroxyapatite. It is in a state of being attached to the surface, and is substantially supported on the surface of titanium dioxide or hydroxyapatite. Although copper and silver were partially in contact with each other, they were not in a molten state. FIG. 4 shows a schematic conceptual diagram showing the binding state of each component of the agent obtained in Experimental Example 2.

The silver content in the obtained agent of Experimental Example 2 corresponds to 0.6 parts by mass with respect to 100 parts by mass of titanium dioxide, and the copper content also corresponds to 1.8 parts by mass with respect to 100 parts by mass of titanium dioxide. Similarly, the content of hydroxyapatite corresponds to 25 parts by mass with respect to 100 parts by mass of titanium dioxide. 35 g of the obtained agent of Experimental Example 2 was dispersed in 65 mL of distilled water to prepare a stock solution of the agent of Experimental Example 2 having a solid content concentration of 35%, which was used for various microbial tests.

[Preparation of Agent of Experimental Example 3]
In Experimental Example 3, an agent consisting of silver particles-copper particles-titanium dioxide particles-Hy particles was prepared in the same manner as in Experimental Example 2 except that the amount of copper added was 3.0 g. The schematic conceptual diagram of the obtained agent of Experimental Example 3 is substantially the same as that of Experimental Example 2 shown in FIG. The silver content in the obtained agent of Experimental Example 3 corresponds to 0.6 parts by mass with respect to 100 parts by mass of titanium dioxide, and the copper content also corresponds to 3.6 parts by mass with respect to 100 parts by mass of titanium dioxide. Similarly, the content of hydroxyapatite corresponds to 25 parts by mass with respect to 100 parts by mass of titanium dioxide. 35 g of the obtained agent of Experimental Example 3 was dispersed in 65 mL of distilled water to prepare a stock solution of the agent of Experimental Example 3 having a solid content concentration of 35%, which was used for various microbial tests.

The compositions of each agent of Reference Example and Experimental Examples 1 to 3 prepared as described above are summarized in Table 1. The reference example is a water-only sample (Blank).

[Measurement of bactericidal effect against Staphylococcus aureus]
The measurement of the effect on Staphylococcus aureus was measured using the agent consisting of each of the silver particles-copper particles-titanium dioxide particles-Hy particles of Experimental Examples 1 to 3 prepared as described above. First, the stock solutions of the agents of Experimental Examples 1 to 3 are diluted 10-fold each, and 10 mL of the test solutions of the agents of Experimental Examples 1 to 3 having a solid content concentration of 3.5% are prepared, and further, a reference example (Blank) is prepared. ) 10 mL of distilled water was prepared as a sample. ^{0.1 mL of 9.0 × 10 7} cfu of Staphylococcus aureus solution was mixed with each of the Blank samples and the samples of Experimental Examples 1 to 4 thus obtained, and the mixture was placed in a constant temperature bath maintained at 25 ° C. The number of Staphylococcus aureus in each sample when maintained for 0 hours, 0.5 hours and 2 hours while being shielded from light was measured by a flat plate agar culture method. The results are summarized in Table 2, FIG. 5 and FIG. Note that FIG. 5 is a diagram showing the relationship between the contact time and the detected number of bacteria, and FIG. 6 is a diagram showing the relationship between the contact time and the log (number of bacteria).

Comparing the results of Experimental Example 1 against Staphylococcus aureus with the results of the agents of Experimental Examples 2 and 3, the following can be seen. That is, the addition of copper as well as silver and titanium dioxide is recognized to improve the initial bactericidal effect. The sterilization rate after 0.5 hours was 27.3% in Experimental Example 1, 39.1% in Experimental Example 2, and 84.0% in Experimental Example 3, and the bactericidal effect was greatly improved. ing. However, such an effect of improving the initial bactericidal effect becomes milder with the passage of time, and the agent of Experimental Example 3 having the largest amount of copper added is substantially the same as the agent of Experimental Example 1 containing no copper after 2 hours. It has the same effect. The result of the agent of Experimental Example 2 in which the amount of copper added was small was that the bactericidal effect was slightly inferior to that of the agent of Experimental Example 1 containing no copper after 2 hours.

This is because copper has a higher ionization tendency than silver, and when moisture is present, copper becomes copper ions and elutes. Therefore, in addition to the bactericidal effect of silver and titanium dioxide, the bactericidal effect of copper ions is also added. Therefore, it seems that it led to the improvement effect of the initial bactericidal effect. However, the results after 2 hours of the agents of Experimental Examples 2 and 3 show the same bactericidal effect as the agent of Experimental Example 1 containing no copper (Experimental Example 3) or a bactericidal effect inferior to that (Experimental Example 2). There is. This point probably means that the surface of the copper particles is not homogeneous, and there are some parts that are easy to dissolve and some parts that are difficult to dissolve. It is presumed that the bactericidal effect of silver and titanium dioxide has come to occupy a large proportion because the easily soluble parts of copper disappear.

From the results shown in Table 1, it was found that a good bactericidal effect was exhibited when the copper content was 2 parts by mass or more with respect to 100 parts by mass of the titanium dioxide particles, and the amount of copper added was large. The larger the amount, the better the initial bactericidal effect is observed, but if the amount is too large, the effect is saturated. Therefore, the copper content is preferably 7 parts by mass or less with respect to 100 parts by mass of the titanium dioxide particles. Interpolating these results, it seems that the more preferable copper content is 2.5 to 4 parts by mass with respect to 100 parts by mass of titanium dioxide.

[Measurement of bactericidal effect on E. coli]
The measurement of the effect on Escherichia coli was measured using the agent consisting of silver particles-copper particles-titanium dioxide particles-Hy particles of each of Experimental Examples 1 to 3 prepared as described above. First, the stock solutions of the agents of Experimental Examples 1 to 3 are diluted 10-fold each, and 10 mL of the test solutions of the agents of Experimental Examples 1 to 3 having a solid content concentration of 3.5% are prepared, and further, a reference example (Blank) is prepared. ) 10 mL of distilled water was prepared as a sample. ^{0.1 mL of 5.0 × 10 6} cfu E. coli solution was mixed with each of the Blank sample thus obtained and each of the samples of Experimental Examples 1 to 4 and placed in a constant temperature bath maintained at 25 ° C. The number of E. coli cells in the sample when maintained for 0 hours, 0.5 hours and 2 hours while being shielded from light was measured by a flat plate agar culture method. The results are summarized in Table 3, FIG. 7 and FIG. Note that FIG. 7 is a diagram showing the relationship between the contact time and the detected number of bacteria, and FIG. 8 is a diagram showing the relationship between the contact time and log (number of bacteria).

The results of Experimental Example 1 and the results of the agents of Experimental Examples 2 and 3 against Escherichia coli were substantially the same as those against Staphylococcus aureus. That is, the addition of copper as well as silver and titanium dioxide is recognized to improve the initial bactericidal effect. The sterilization rate after 0.5 hours was 27.3% in Experimental Example 1, 39.1% in Experimental Example 2, and 84.5% in Experimental Example 3, and the bactericidal effect was greatly improved. ing. However, such an effect of improving the initial bactericidal effect becomes milder with the passage of time, and the agent of Experimental Example 3 having the largest amount of copper added is substantially the same as the agent of Experimental Example 1 containing no copper after 2 hours. It has the same effect. The result of the agent of Experimental Example 2 in which the amount of copper added was small was that the bactericidal effect was slightly inferior to that of the agent of Experimental Example 1 containing no copper after 2 hours. The reason for this is also considered to be the same as the difference in the bactericidal effect due to the difference in the copper additive for Staphylococcus aureus, and the preferable copper content ratio is 7 parts by mass or less with respect to 100 parts by mass of the titanium dioxide particles. It is preferable that 2.5 to 4 parts by mass is more preferable with respect to 100 parts by mass of titanium dioxide.

According to the above description of Non-Patent Document 1, the bactericidal effect on E. coli in water is sufficient at a concentration of 5 ppm in the case of silver ions, but the silver ion concentration in the case of copper ions. It has been shown that the bactericidal effect equivalent to that in the case where the silver ion concentration is 5 ppm is exhibited at 625 ppm, which is 100 times or more the above. However, in the agents of Experimental Examples 2 and 3 of the present application, copper coexists with silver metal in the form of a metal, and both copper metal and silver metal dissolve in a very small amount (or hardly dissolve) in about 2 hours. ), It is estimated that the copper ion concentration in the test sample is at most several ppm to several tens of ppm, and the silver ion concentration is much lower than that. That is, according to the agent of the present invention, although the copper ion concentration and the silver ion concentration are much lower than those disclosed in Non-Patent Document 1, the bactericidal effect on Escherichia coli is the same as in the case of Non-Patent Document 1. By adopting the form of the agent of the present invention, a synergistic effect that cannot be predicted from the conventional agents such as Non-Patent Document 1 is exhibited.

[Modifications 1 to 3]
In Experimental Examples 2 and 3, an agent consisting of silver particles-titanium dioxide particles-Hy particles (Experimental Example 1) is first prepared, and then copper particles are added and stirred or mixed in a ball mill to obtain silver particles-. An agent consisting of copper particles-titanium dioxide particles-Hy particle agent was prepared. However, the agent of the present invention is not limited to such a structure, and first, the titanium dioxide particles and the silver particles are stirred or mixed in a ball mill to prepare composite particles composed of silver particles-titanium dioxide particles. Then, copper particles may be added, and then hydroxyapatite particles may be added to prepare the agent of Modification 1 consisting of silver particles-copper particles-titanium dioxide particles-Hy particle agent. In the agent of the first modification, the titanium dioxide particles and the silver particles have a physical bond that bites into the silver particles, and the copper particles are substantially supported on the titanium dioxide. Further, the hydroxyapatite particles are bonded in a state of being supported on titanium dioxide, silver particles or copper particles.

Further, first, a composite particle composed of silver particles-copper particles-titanium dioxide particles is prepared by stirring or mixing titanium dioxide particles, silver particles, and copper particles in a ball mill, and then hydroxyapatite particles are supported. Thereby, the agent of Modification 2 composed of silver particles-copper particles-titanium dioxide particles-Hy particles may be prepared. In the agent of this modification 2, the silver particles and the titanium dioxide particles form a physical bond so that most of them bite into each other, but since copper is harder than silver, a part of the copper particles and the titanium dioxide particles are used. It is physically bonded so as to bite into it, and the remaining copper particles are bonded in a state of being supported on the surface of titanium dioxide. The hydroxyapatite is bonded to the surface of titanium dioxide, silver particles or copper particles.

Furthermore, first, titanium dioxide particles and silver particles are stirred or mixed in a ball mill to prepare composite particles consisting of silver particles-titanium dioxide particles, and then copper particles are added to prepare silver particles-copper particles-. The agent of Modification 3 made of titanium dioxide particle agent may be prepared. That is, an adsorbent such as hydroxyapatite is not bound to the agent of the modified example 3. In the agent of the third modification, the titanium dioxide particles and the silver particles have a physical bond that bites into the silver particles, and the copper particles are bonded in a state of being substantially supported on the titanium dioxide. Also in the modified example 3, for example, the same effect as the effect having continuously under light irradiation for a long period of time without light irradiation against bacteria, viruses, allergens, fungi, odorous substances, harmful substances and the like can be obtained.

Further, in Experimental Examples 2 and 3 above, examples were shown in which the particle size of the silver particles and the average particle size of the copper particles were both 300 nm, but these particle sizes have clear critical limits. However, it may be in the range of 100 nm to 1 μm. Further, an example was shown in which the content of silver particles was set to 6 parts by mass with respect to 100 parts by mass of titanium dioxide, but the critical limit of this content is not clear, and titanium dioxide is also considered from the viewpoint of action effect and economy. The range may be 0.1 to 5 parts by mass with respect to 100 parts by mass, and more preferably 0.2 to 2 parts by mass.

Further, in each of the above experimental examples, an example in which titanium dioxide particles are used as the metal oxide forming composite particles together with silver particles is shown, but titanium dioxide can also be used even if tungsten oxide particles are used instead of titanium dioxide particles. As in the case of using, it is natural that there is light irradiation, and even when there is no light irradiation, the same effect as that which is produced when there is better light irradiation can be obtained. become

Further, in each of the above experimental examples, an example in which hydroxyapatite is used as an adsorbent is shown, but in addition, well-known adsorbents such as zeolite, sepiolite, apatite, and activated carbon can also be used. Although the critical limit of the adsorbent particle size is not clear, for example, when hydroxyapatite is used as the adsorbent, 0.3 to 50 μm is particularly desirable in order to secure a wider surface area and achieve good working performance.

Further, the content ratio of the adsorbent is not a critical limit, but is preferably 10 to 50 parts by mass with respect to 100 parts by mass of the titanium dioxide or tungsten oxide particles. If the content ratio of the adsorbent is less than 10 parts by mass with respect to 100 parts by mass of the titanium dioxide or tungsten oxide particles, the effect of adding the adsorbent will not be exhibited. Further, when the content ratio of the adsorbent exceeds 50 parts by mass with respect to the titanium dioxide or tungsten oxide particles, the content ratio of the composite particles and at least one selected material is relatively reduced, so that the above effect is reduced. do. When hydroxyapatite is used as the adsorbent, the content ratio of the adsorbent is more preferably 20 to 30 parts by mass with respect to 100 parts by mass of titanium dioxide or tungsten oxide particles.

On the other hand, it is possible to obtain an agent which has the same effect as the effect which is continuously exposed to light for a long period of time without irradiation with light and which can exert these effects in a short time.

[Experimental Example 4]
In Experimental Example 4, the behavior when impregnated or applied to a woven fabric, a non-woven fabric or paper using water having various hardness together with the agent prepared in Experimental Example 1 was investigated. First, as water of various hardnesses, 12 kinds of water in PET bottles such as commercially available mineral water were prepared. The hardness of these 12 types of water varied from 1612 to 9.9, depending on the place of origin or brand. For example, a hardness of 1612 is referred to as "Cool Mayor" (trade name (same below)), a hardness of 304 is referred to as "Evian", a hardness of 60 is referred to as "Volvic", and a hardness of 30 is referred to as "natural water of the Southern Alps". The one with a hardness of 9.9 is commercially available as "natural water of Kumano Kodo". As the water having a hardness of 0, pure water obtained through an ion exchange resin was used.

First, 13 kinds of water having a hardness of 1612 to 0 were individually injected into a 200 mL graduated cylinder at room temperature so as to be 200 mL. Next, 10 mL of the stock solution of the agent obtained in Experimental Example 1 was added to each measuring cylinder, mixed well, and then allowed to stand, and the height (mm) of the agent that aggregated and settled with the passage of time was measured. It was measured. The results are summarized in Table 4.

Next, 200 mL of water having hardnesses of 85, 60, and 30 was injected into each of the three beakers, and 10 mL of the stock solution of the agent obtained in Experimental Example 1 was further added to each beaker, mixed well, and then the same. A cloth piece sample of a size is immersed for 5 minutes, then the excess water is wiped off with a filter paper, and then the cloth piece sample is dried at 70 ° C. for 5 minutes to obtain three pieces of the cloth piece sample processed with the agent of the present invention. rice field. Then, each of the obtained three pieces of cloth was observed with an electron microscope at a magnification of 1000 times. The results are summarized in FIG. 17A shows the agent of the present invention and water having a hardness of 85, FIG. 17B shows the agent of the present invention and water having a hardness of 60, and FIG. 17C shows the agent of the present invention and the hardness 30. It is an electron micrograph when using the water of.

From the results shown in Table 4, the agent obtained in Experimental Example 1 aggregates and precipitates after about 3 minutes when the hardness of water exceeds 60, and aggregates and precipitates after 5 minutes. You can see that it is doing. On the other hand, when the hardness of water is 60 or less, almost no agglutination occurs even after 5 minutes, and no sedimentation is substantially observed. In particular, when the hardness is 40 or less, almost no aggregation is observed even after 10 minutes, and no sedimentation is substantially observed. In addition, the results shown in FIG. 17A show that there is a lot of agglutination and the product is defective. The results shown in FIG. 17B show that there is little agglutination and the product is sufficiently applicable as a commercial product. Further, according to the result shown in FIG. 17C, it can be seen that agglutination is further reduced and a good quality product can be obtained.

In order to adsorb or adhere the agent of the first embodiment to fibers such as woven fabric, non-woven fabric or paper, for example, impregnation or coating, if the treatment time is as short as about 1 minute, the coexisting water hardness does not matter. Although it is unlikely that agglomeration will occur, if the time required for the drying / heat treatment step after the treatment is taken into consideration, agglomeration may occur during this step, which may adversely affect the quality of the final product. Therefore, when the results shown in Table 4 and FIGS. 17A to 17C are comprehensively taken into consideration, the hardness of the coexisting water is preferably 60 or less so that the treatment time can be secured for 5 minutes or more. You can see that. The hardness of water is preferably 40 or less in order to secure a longer treatment time. Further, when the hardness of water is 30 or less, agglutination is further reduced, which is more preferable.

Next, the means for adsorbing or adsorbing the agent of the present invention to fibers such as woven fabric, non-woven fabric or paper will be described with reference to FIGS. 18 to 20. 18A is a conceptual diagram showing a process of adhering the agent of the present invention and water having a predetermined hardness to sewn clothes using a processing device having a drum-type washing machine, and FIG. 18B is a conceptual diagram showing the processing of FIG. 18A. It is a conceptual diagram which shows an example of a device. FIG. 19 is a schematic view of a continuous processing apparatus for adhering the agent of the present invention and a predetermined soft water to the raw fabric of a textile product. Further, FIG. 20 is a schematic view of a continuous processing apparatus for adhering the agent of the present invention and a predetermined soft water to the raw fabric of a textile product by a screen printing method.

The processing apparatus 40 shown in FIG. 18A comprises a drum-type washing machine as used in, for example, a coin laundry, and supplies a mixed solution 42 of the agent of the present invention and a predetermined soft water to an internal drum 41.
