Antibacterial composition and antibacterial material

Technical field

[0001] The present invention relates to an antibacterial composition and an antibacterial material. Specifically, the present invention relates to an antibacterial composition and an antibacterial material containing iodine.

Background art

[0002] Microbes such as various bacteria and molds exist in our living space. These organisms can cause us to feel uncomfortable, causing food rot and odors. In addition, the human body causes various diseases such as food poisoning. In order to live a hygienic life, it is important to suppress the growth of these microorganisms or to remove these microorganisms.

[0003] From this point of view, various proposals have been made for the purpose of providing a clean living space. As one of them, iodine is attracting attention. This is because iodine has a broad antibacterial spectrum, while having excellent antibacterial properties that are highly safe for humans.

[0004] However, iodine tends to sublime even at room temperature. For this reason, if iodine is used alone for applications such as antibacterial and deodorizing, there is a problem that sufficient effects cannot be obtained by sublimation of iodine.

[0005] Various iodine holes have been proposed for the purpose of reducing the volatility of vegetative iodine to compensate for these disadvantages (for example, Japanese Patent Publication No. 60-19762, US Pat. No. 2739922). U.S. Pat. No. 3028300 and JP-A-51-88625). As a specific example of the odor hole, Japanese Patent Publication No. 60-19762 discloses a complex of chitosan and iodine as a carrier. In addition, U.S. Pat. No. 2739922 and U.S. Pat. No. 3028300 disclose a composite of polyvinylpyrrolidone (PVP), which is a carrier, and iodine (hereinafter also referred to as “Povidone”). . JP-A-5-88625 discloses an iodine-cyclodextrin inclusion complex (hereinafter also referred to as “CDI”) in which an iodine atom is included in a cyclodextrin !, The [0006] An attempt has been made to impart antibacterial properties to the base material by holding these pseudo holes on the base material to obtain an antibacterial material. For example, Japanese Unexamined Patent Publication No. 2001-89974 discloses a fiber base material in which povidone is held on a fiber surface together with a predetermined polymer. Japanese Patent Application Laid-Open No. 51-100892 discloses a sterilized and antiseptic packaging paper provided with a β-cyclodextrin inclusion product of iodine.

[0007] Like the techniques described in JP-A-2001-89974 and JP-A-51-100892, if iodine is held on a fiber substrate in the form of a odor hole, iodine is used alone. In comparison, sublimation of iodine is suppressed, and the sustainability of antibacterial and deodorizing effects can be improved.

JP-A-63-225308 and JP-A-2-110 disclose a powder having a property of foaming by reacting with an iodine carrier, an iodide, an oxidizing agent, a powdered acid and, if necessary, a powdered acid. A solid odor hall composition (formulation) containing a base is disclosed. According to these techniques, a solid squeeze hole composition (formulation) that is easy to manufacture and stable can be provided.

Disclosure of the invention

[0009] However, even in an antibacterial material (for example, a sheet-like antibacterial material) in which a hooded hole is held on a base material, a certain amount of iodine is sublimated from the base material surface and held on the base material. Reduced iodine concentration. As a result, the antibacterial action also decreased over time, and as a result, the antibacterial action sometimes disappeared. The substrate surface force can also sublimate iodine because the sterilization and antiseptic mechanism of the wrapping paper described in Reference 6 is based on sublimated iodine (I) released into the package space. It is clear from

[0010] By the way, in the above hole, iodine is triiodide ion (I-) or pentaiodine.

It is thought that it is contained in the form of trioxide ion (I ").

Five

[0011] When sterilizing action is exerted by contact with iodine power pollutants, etc. contained in the form of ions such as in the horde hall, microorganisms such as bacteria, fungi, protozoa, viruses in the pollutants and These ions are reduced by reaction with organic substances and iodide ions (Γ) are generated.

[0012] However, the strong iodide ion (Γ) is once again transferred to the Eodohole carrier (for example, poly When it is taken up into bullpyrrolidone (cyclodextrin) and regenerates hordeol, the antibacterial activity disappears after almost a certain time. On the other hand, if a high concentration of hordehole is added to the preparation for the purpose of obtaining a sufficient effect, the antibacterial material exhibits an iodine color, and there is a problem in appearance when applied to a product labeled “antibacterial”. In addition, even during use, there is a repulsive force S in which iodine color adheres to the object to be processed or corrosion of the object to be processed occurs. However, in order to treat the antibacterial material for a certain period of time even if there is such a problem, the problem of appearance and corrosion should be ignored and compared with the amount required for the first effect. An excess of iodine (I) had to be present.

[0013] Therefore, in an antibacterial material using iodine, it is currently desired to develop a technology for effectively using the contained iodine and maintaining a low concentration of iodine over a long period of time. is there.

[0014] Therefore, an object of the present invention is to provide a means that enables effective use of iodine in an antibacterial material using iodine.

[0015] The present inventors have conducted intensive research to solve the above problems. In the process, if an excessive amount of an iodine-based oxidant such as iodate is present in an iodine-based compound such as an iodide salt, iodine is produced after exhibiting antibacterial properties.

It was learned that 3- and 5- could be regenerated, and that iodine-based oxidants could also act as iodine sources. Furthermore, it is generated and regenerated in response to the amount of iodine compound added.

Taking advantage of the determination of the amount of 3— and 5—, low concentrations of iodine (I— and I—) can be kept stable over long periods of time by adding small amounts of iodine compounds. I knew that. That is,

3 5

The inventors have found that effective use of iodine can be achieved by adopting a powerful configuration, and have completed the present invention. In addition, in the solid sward-hole composition (formulation) described in JP-A-63-225308 and JP-A-2-110 described above, the following knowledge that an iodine-based oxidizing agent is essential is described. However, iodine-based oxidants are only listed as examples of the many oxidants listed to oxidize iodide ions (Γ). On the other hand, if an oxidizing agent other than an iodine-based oxidizing agent is used in the antibacterial composition or antibacterial material of the present invention, a small amount of coexisting iodine-based compounds are instantly oxidized and the reaction is terminated. After I— and I— are consumed over time, Since the regeneration is not performed, the antibacterial composition and the antibacterial material are exhausted, and the effects of the present invention cannot be obtained. Further, in all of the examples described in the above documents, the content of iodine-based oxidant is less than the content of S-iodine compound (iodide). Can hardly be expected.

[0016] Specifically, according to one aspect of the present invention, an iodine compound (A), an iodine oxidant (B), and an acid compound (C), the iodine compound (A ) And the iodine-based oxidizing agent (B) in a mass ratio of (B) / (A) = 1 to: LOOO.

[0017] Further, according to another embodiment of the present invention, a solid base material, an iodine-based compound (A), an iodine-based oxidant (B), and an acid held inside or on the surface of the solid base material A compound (C), wherein the mass ratio of the content of the iodine compound (A) and the iodine oxidant (B) is (B) Z (A) = 1: LOOO Material is provided. Here, the solid substrate is preferably a sheet-like substrate or a granular substrate. Furthermore, the above antibacterial composition and antibacterial material can be used as an antibacterial agent for rugs, dipping, filters, wiping, spraying, or filling.

[0018] Further objects, features, and characteristics of the present invention will become apparent by referring to the following description and preferred embodiments illustrated in the accompanying drawings.

BEST MODE FOR CARRYING OUT THE INVENTION

[0022] (First embodiment)

According to one aspect of the present invention, the iodine compound (A), the iodine oxidant (B), and the oxide compound (C) are contained, and the iodine compound (A) and the iodine oxidant are included. An antibacterial composition is provided in which the mass ratio of the content to (B) is (B) Z (A) = 1 to: LOOO. In the present invention, “antibacterial” is a concept that means that the growth of microorganisms is suppressed by iodine. This concept includes a bactericidal action in which microorganisms are killed by iodine and a slight effect by iodine. These include both the bacteriostatic action that maintains the living state of the organism but suppresses its growth. Microorganisms whose growth is suppressed by the antibacterial composition of this embodiment and the antibacterial material described below are not particularly limited, and include viruses and fungi in addition to bacteria.

[0023] Hereinafter, preferred embodiments of the present invention will be described in detail for each component, but the technical scope of the present invention is not limited to the following specific forms.

[0024] [Iodine compound (A)]

The antibacterial composition of the present embodiment first contains an iodine compound (A). Here, the “iodine-based compound” means a compound that can generate iodide ions (Γ) upon contact with moisture, an organic solvent, or in some cases, air. In this way, it is oxidized to I- and I- by the action of iodine-based oxidant 14 described in detail later, and exhibits antibacterial action. However,

3 5

The compound contained in the boron-based oxidant (B) is not included in the concept of the iodine-based compound (A).

[0025] The specific type of the iodine-based compound (A) is not particularly limited as long as it is a compound exhibiting the above-described action. Examples include iodide salts such as potassium iodide (KI) and sodium iodide (Nal). In some cases, iodine molecules alone (I)

It may be used as a disulfide compound (A). In addition, only one of these iodine compounds (A) may be used alone or two or more of them may be used in combination.

[0026] [Iodine-based oxidizing agent (B)]

Secondly, the antibacterial composition of this embodiment contains an iodine-based oxidizing agent (B). Here, the “iodine-based oxidant” means an activity capable of oxidizing Γ generated from the above iodine-based compound (A) to I— or I—.

3 5

It means a compound capable of producing a sex species. Specific examples of the active species include hypoiodite ion (ιο_), iodate ion (IO-), and periodate ion (IO-).

3 4 These ions are oxidized by increasing the concentration of r by contact with moisture, I— and I “

3 Convert to 5. To explain this mechanism in detail, the following chemical reaction formulas (1) to (3):

[0027] [Chemical 1]

I 0 _ + I-+ 2 H ⁺ → I ₂ + H ₂ 0 (1)

3 I 0 ₃ — + I _ + 1 8 H + → 2 I ₂ + 9 H ₂ 0 (2)

I 0 ₄ — + I— + 8 H + → I ₂ + 4 H ₂ 0 (3) [0028] Oxidized to iodine molecules (I) in accordance with I- and I "

2 3 5 is generated. The I— and I— produced in this way can exert antibacterial action again. That is,

3 5

Effective utilization of iodine is achieved. In addition, the amount of I- and I-

3 5

Therefore, according to the antibacterial composition of this embodiment, the amount of I— and I— is kept at a low concentration throughout.

3 5

It is possible. As a result, it is possible to extend the life of the antibacterial composition, and it can be freed from corrosion and color problems. It should be noted that the above mechanism is merely a guess, and the technical scope of the present invention is not affected at all even if the effects of the present invention can be obtained by mechanisms other than those described above.

[0029] In the present invention, the iodine-based oxidizing agent (B) not only functions as a source of the active species but also contains iodine through the reactions of the above reaction formulas (1) to (3). It also functions as a supply source. Therefore, according to the present invention, by employing a compound containing iodine as an oxidant for oxidizing iodide ions to form a silicon molecule, the effect of the present invention for effective use of iodine is further improved. It can be further demonstrated. As described above, these effects cannot be obtained when an oxidizing agent other than iodine-based oxidizing agents is used.

[0030] The specific type of the iodine-based oxidizing agent (B) is not particularly limited as long as it is a compound that can generate the active species by contact with moisture. Examples include iodic acids such as hypoiodous acid (HIO), iodic acid (HIO), paraperiodic acid (HIO), periodic acid (HIO),

3 4 5 6

Metal salts of the above iodic acids (for example, sodium salt, potassium salt, etc.), I (IO)

3 Iodine salts such as 3 and iodic acid (I 0), iodine trioxide (I O), iodine pentoxide (I o),

2 2 3 2 5 Iodic acid compounds such as silicon (I Ο) and iodine tetroxide (IO). These iodine

2 7 4

As the elemental oxidant (B), only one kind may be used alone, or two or more kinds may be used in combination.

[0031] [Acid compound (C)]

As can be seen from the chemical reaction formulas (1) to (3), the mechanism of I— and I— generation from soot

3 5

In this case, hydrogen ions are consumed. Therefore, in order for I- and I- to be generated when the antibacterial composition of this embodiment comes into contact with moisture, the above mechanism proceeds, so

3 5

Moisture in contact with the fungal composition must be acidic. For this reason, the antibacterial composition of the present embodiment thirdly contains an acid compound (C). Here, “acid compound” means contact with moisture. It means a compound that can make the water more acidic. For example, in addition to acids, salts of strong acids and weak bases can be mentioned. There are no particular restrictions on the specific examples of the acid compound, but as an example, the acid includes citrate monohydrate, succinic acid, malic acid, oxalic acid, tartaric acid and the like. Derivatives such as these hydrates may be used. In addition to the acid, the oxides include salts of strong and weak bases such as ammonium chloride, ammonium sulfate, and ammonium iodide, as well as acid salts such as sodium hydrogen sulfate and phosphorus. Potassium dihydrogen acid, basic salts such as salt, sodium hydroxide, and magnesium can be used. In addition, as for these acid compounds (C), only 1 type may be used independently and 2 or more types may be used together.

[0032] The specific configuration of each component contained in the antibacterial composition of the present embodiment has been described above, but the content of each component in the antibacterial composition is not particularly limited, and the above chemical reaction formula ( It can be adjusted as appropriate by considering the stoichiometric ratio, production method, presence or absence of additives in (1) to (3). However, in the antibacterial composition of the present embodiment, the content ratio between the iodine compound (A) and the iodine oxidant (B) is controlled to a value within a predetermined range. Specifically, the mass ratio of the content of the iodine compound (A) and the iodine oxidant (B) is controlled so that (B) Z (A) = 1 to 1000. As described above, when the content of each component is controlled so that the content of the iodine-based oxidizing agent (B) is equal to or greater than the content of the iodine-based compound (A), the above mechanism is good. The iodine contained in the composition can be effectively utilized. Further, (8) 7 (eight) = 5 to 200 is preferable, and (8) 7 (eight) = 10 to 100 is preferable. Here, if the value of (B) Z (A) is too small, the number of times the reactions represented by the chemical reaction formulas (1) to (3) proceed will decrease, so that the regeneration of iodine is completed in a short period of time. As a result, there is a possibility that the effect of the present invention of effectively utilizing iodine cannot be obtained.

[0033] The content of each component contained in the antibacterial composition is not particularly limited as long as the above-mentioned regulations are satisfied. However, in a preferred form, the content of the iodine compound (A) is preferably 0 with respect to the total amount of the composition as long as the iodine produced by oxidation is sufficient to exhibit an antibacterial action. 001 to 10% by mass, more preferably 0.005 to 5% by mass, and still more preferably 0.01 to 3% by mass. In addition, the content of the iodine-based acid additive (B) is controlled so that the mass ratio with the iodine-based compound (A) is a value within the above range. For products (C), all iodine-based oxidants (B) A sufficient amount may be used to adapt. Accordingly, the content of the iodine-based oxidant (B) is preferably 1 to 95% by mass, more preferably 5 to 90% by mass, and further preferably 10 to 80% with respect to the total amount of the composition. % By mass. In addition, the content of the acid compound (C) is preferably 1 to 95% by mass, more preferably 5 to 90% by mass, and further preferably 10 to 80% by mass with respect to the total amount of the composition. It is. Here, if the content of iodine compound (A) is too large, the initial amount and regeneration amount of iodine (i.e., the amount of iodine concentration maintained) becomes too large, improving the corrosivity and color tone, and reducing the concentration at low concentrations. The effects of the present invention, such as stabilization of iodine, may not be sufficiently exhibited. On the other hand, if the content of the iodine-based oxidant (B) is too large, the amount of the acid compound (C) necessary to consume all the iodine-based oxidant (B) will increase, and antibacterial activity will occur. There is a possibility that the acidity of the sexual composition may increase excessively. If various additives described later are added, the contents of (A) to (C), which are essential components in the antibacterial composition, may be out of the above-mentioned range. However, it can be included in the technical scope of the present invention.

[0034] It should be noted that JP-A-2000-507217, JP-A-59-202248, JP-A-56-99419, JP-A-53-148540, etc. also disclose iodine-based compounds and iodine-based compounds. Disinfectant compositions comprising an oxidizing agent and an acid compound are disclosed. However, in the techniques described in these documents, iodine-based oxidizers are added for the purpose of stabilizing separately added iodine and iodine holes. In combination with a silicon-based oxidant, I

3 _ and I

There is no disclosure or suggestion about the purpose and effect of this application to maintain 5- at a low concentration. In addition, the inventions described in these documents can be expected to have the same effect even when an oxidizing agent other than iodine-based oxidizing agents is used, and iodine-based oxidizing agents are described in parallel with other oxidizing agents. It has only been done.

[0035] The antibacterial composition of the present embodiment may further contain other additives as required! There are no particular restrictions on specific forms of other additives, and conventionally known findings can be referred to as appropriate. Preferable additives include, for example, compounds that can form a complex with iodine. Examples of the compound that can form a complex with iodine include cyclodextrin (CD), polyvinylpyrrolidone (PVP), glycine, and the like. Add these compounds As a result, the sublimation and corrosion properties of iodine are alleviated. Of these, cyclodextrin is preferably included. In addition to the above-mentioned effects, the cyclodextrin additive provides a deodorizing effect by including various compounds in the pollutant in its own cyclic structure. “Cyclodextrin” is a compound in which D-glucose is bound cyclically by α-1,4 bonds. Cyclodextrins are broadly classified into 6 cyclodextrin (6), β-cyclodextrin (7), and γ-cyclodextrin (8) according to the number of D-glucose that constitutes it. Any of these may be used in the antibacterial composition of this embodiment.

[0036] The specific form of cyclodextrin is not particularly limited, and a conventionally known form can be appropriately employed. Of course, not only the above three cyclodextrins but also derivatives thereof may be used. Examples of cyclodextrin derivatives include alkylated (methylated, ethylated, propylated, isopropylated, butylated, etc.), monoacetylated, triacetylated, monochlorotriazinylated. Specific examples of cyclodextrin include those commercially available as CAVAMAX (registered trademark) series and CAVASOL (registered trademark) series (both manufactured by Sakka). In addition, other cyclodextrins such as a maltosyl group-substituted cyclodextrin commercially available as Dextrin Pearl or Isoelite (manufactured by Yokohama International Bio-Laboratory Co., Ltd.) may be used. Of these cyclodextrins, only one kind may be used alone, or two or more kinds may be used in combination.

[0037] As described above, the cyclodextrin contained in the antibacterial composition can exert a deodorizing action by including various compounds in the contaminants in its cyclic structure. In this form, cyclodextrin is produced by the above mechanism I- or I-

By inclusion of 35, iodine-cyclodextrin inclusion compound (CDI), which is a kind of iodine hole, can be produced. Therefore, when I— or I— decomposes, it becomes I and sublimates.

3 5 2

It is expected that the antibacterial durability will be improved when the antibacterial composition is used. In some cases, in the antibacterial composition of the present embodiment, the cyclodextrin mono-iodine inclusion complex in which part or all of the cyclodextrin is initially included in the inclusion of iodine is also included. Also good. In addition, the antimicrobial composition of this form can form a complex with iodine. When the compound is contained, the content of the compound that can form a complex with the iodine is not particularly limited, but is preferably 0 to 90% by mass, more preferably 0 to 80%, based on the total amount of the composition. % By mass, more preferably 0 to 70% by mass.

[0038] The antibacterial composition of the present embodiment may contain a known antibiotic or synthetic antibacterial if necessary. Known antibiotics include, for example, penicillins, cefems, strong rubapenems, monobatams, etc. —lactam antibiotics; aminoglycoside antibiotics; macrolide antibiotics; tetracycline antibiotics Chloramphenicol; lincomycin; fosfomycin; peptide antibiotics; and antifungal antibiotics. Examples of synthetic antibacterial agents include naliditasic acid, new quinolone antibacterial agents, and azole antifungal agents. In addition, it is not restricted only to these, The various compounds used as an external preparation and a disinfectant can be added as an additive. In some cases, an antiviral agent may be added. In addition, as for the exemplified additives, only one kind may be used alone, or two or more kinds may be used in combination.

[0039] The antibacterial composition of the present embodiment may be a powdery composition obtained by mixing the above-described essential components (i) to (C) and an additive as necessary. An aqueous solution-like composition further containing According to the form of the aqueous solution, there are advantages that handling and storage are easy and that the applicable range is widened because it can be used by spraying or spraying. When the composition of this embodiment further contains water, the amount of water added is not particularly limited, but is preferably 1 to 2000 times by mass, more preferably 2 to 1000 times the total amount of components other than water. It is mass times, More preferably, it is 20-500 mass times. However, it is needless to say that a form outside these ranges may be adopted.

[0040] The production method of the antibacterial composition of the present embodiment is not particularly limited, and conventionally known knowledge relating to the production of a powdery composition or an aqueous solution composition can be appropriately referred to. For example, if you want to manufacture a powdery composition, prepare the components of the composition, and then granulate or pulverize each prepared component to the desired particle size and mix homogeneously with a mixer!ぅ method can be used. In some cases, granulation and pulverization may be performed simultaneously with mixing. In addition, in the case where an aqueous composition is produced !, in the case where a predetermined amount of components of the composition is weighed, added to water, and dissolved by stirring. However, the hand mentioned above Of course, other methods may be used.

Hereinafter, preferred embodiments of the present embodiment will be described with reference to the drawings. However, the technical scope of the present invention is not limited by the following forms or the illustrated forms. For example, in the following explanation, the antibacterial material of this embodiment will be described in detail by taking a sheet-like antibacterial material using a sheet-like substrate as a solid substrate as an example, but it is limited only to such a form. not

A granular antibacterial material in which a granular substrate as described below is used as a solid substrate is also included in the technical scope of the present invention.

[0043] FIG. 1 is a cross-sectional view showing one preferred embodiment of the antibacterial material of the present embodiment. The antibacterial material in the form shown in FIG. That is, the sheet-like substrate 12 is used as the solid substrate. In the sheet-like antibacterial material 10 shown in FIG. 1, an iodine-based compound (A) 14, an iodine-based oxidant (B) 16, and an oxidized compound (C) 18 are held inside a sheet-like base material 12. It has the composition which becomes. In the form shown in FIG. 1, each component is held only inside the sheet-like base material 12, but is not limited to such a form. For example, a form in which each of the above components is held only on the surface of the sheet-like base material 12 or a form in which both of the components are held on the inside and the surface of the sheet-like base material 12 can also be adopted. Further, when each component is held on the surface of the sheet-like substrate 12, it may be held only on one side of the sheet-like substrate 12, or may be held on both sides of the sheet-like substrate 12. ,.

[0044] [Sheet substrate]

The sheet-like antibacterial material 10 having the form shown in FIG. 1 includes a sheet-like substrate 12 as a solid substrate.

[0045] The specific form of the sheet-like substrate 12 is not particularly limited. Examples of the constituent material of the sheet-like substrate 12 used for the sheet-like antibacterial material 10 of this embodiment include paper, woven fabric, and non-woven fabric. For paper, Japanese paper, filter paper, drawing paper, high-quality paper, cardboard paper, cardboard Recycled paper, synthetic paper, white paperboard, yellow paperboard, chipball, colored paperboard, building material base paper, backing paper, thin paper, thermal paper, synthetic fiber paper, etc. are included. Either organic fiber or inorganic fiber may be used as a raw material for the woven fabric and the nonwoven fabric. Here, the organic fibers include plant fibers, animal fibers, regenerated fibers, semi-synthetic fibers, synthetic fibers, and the like. In addition, inorganic fibers include glass fibers, carbon fibers, ceramic fibers, and the like. Sarayoko and plant fibers include wood pulp, straw pulp, bamboo pulp, kenaf pulp, and other woods, herbs, cotton, hemp, etc. Animal fibers include silk, wool, etc. Fiber. Examples of recycled fibers include rayon and cuvula. Examples of semi-synthetic fibers include acetate, triacetate, and promix. Examples of synthetic fibers include nylon, acrylic, vinylon, vinylidene, polyvinyl chloride, polyester, polyethylene, and polypropylene. , Benzoate, polyclar

And fibers such as phenol. In addition, as the sheet-like base material 12, a commercially available one may be used, or a self-synthesized one may be used.

[0046] The size and shape of the sheet-like substrate 12 can also be appropriately determined according to the use of the sheet-like antibacterial material, which is not particularly limited.

[0047] The specific form such as the type of each component held on the sheet-like base material 12 is as described in the column of the first embodiment, and thus the description thereof is omitted here.

[0048] Also in the antibacterial material of this embodiment, when each component is held on a solid substrate, the mass ratio of the content of the iodine compound (A) and the iodine oxidant (B) is: B) / (A) = 1 ~: Controlled to be LOOO. Similarly, in the antibacterial material of this embodiment, when the content of each component is controlled so that the content of the iodine-based oxidizing agent (B) is equal to or higher than the content of the iodine-based compound (A), This mechanism proceeds well and iodine contained in the antibacterial material can be effectively used.

[0049] Although the antibacterial material of this embodiment is !, the content of each component contained therein is not particularly limited as long as the above-mentioned regulations are satisfied. For example, the content of iodine compound (A) is sufficient depending on the type of solid substrate (for example, non-woven fabric or paper) as long as the concentration of iodine generated by oxidation is sufficient to exhibit antibacterial action. The specific gravity can vary accordingly, so it is difficult to define it unambiguously. However, in a preferred form, the content of the iodine-based compound (A) is preferably from 0.0001 to 20% by mass relative to the total amount of the antibacterial material. Preferably it is 0.0001-5 mass%, More preferably, it is 0.0001-1 mass%. In addition, the content of the silicon-based oxidant (B) is controlled so that the mass ratio with the iodine-based compound (A) is a value within the above range, and further, For product (C), use an amount sufficient to react all the iodine-based acid oxidants (B).

[0050] When the sheet-like antibacterial material 10 comes into contact with moisture during use, I- and I- are generated by the mechanism described above. Since these ions exhibit iodine color, the sheet of this embodiment

3 5

The antibacterial material can be visually identified as before or after use. However, in the sheet-like antibacterial material 10 of this embodiment, iodine can be reused by the mechanism described above. Therefore, even when it is iodine color and is identified as “after use”, it can sufficiently exhibit antibacterial action.

[0051] Also in the antibacterial material of the present embodiment, other additives may be further retained on the solid substrate as necessary. Examples of the additive that can be further retained on the solid substrate include the additives described in the column of the antibacterial composition of the first embodiment.

[0052] In this embodiment, other additives can also be used effectively. For example, although iodine exhibits an antibacterial effect, iodine color is similar in color to common contaminants. For this reason, it may be aesthetically unfavorable to use the sheet-like antibacterial material 10 of the present embodiment once again after exhibiting iodine color. From the viewpoint of strength, it is preferable that the sheet-like base material 12 holds starch or a derivative thereof in the sheet-like antibacterial material 10 of the present embodiment. According to the form of force, when I— or I— is generated by the above mechanism,

3 5

Form a complex with starch and its derivatives and show a bright blue-purple color (so-called “iodine-starch reaction”). Therefore, the adverse effect on the aesthetics caused by the coloration of the once used sheet-like antibacterial material 10 can be reduced. I- and I- are starches and their derivatives.

3 5

Even when it forms a complex with the body, it can exhibit antibacterial action.

[0053] As other additives, for example, when the solid substrate is paper, an internal adhesive mainly composed of cationic dampening or amphoteric starch, a paper strength agent such as polyacrylamide, talc, Various fillers such as diatomaceous earth and acid titanium, dyes such as garlic, pigments such as chrome yellow, various sizing agents such as rosin, starch, rice bran, carboxymethylcellulose, polyvinyl alcohol, glycerin Brighteners, surfactants, fragrances, etc. Dyes, pigments, etc. can be retained. In addition, when the solid substrate is a nonwoven fabric made of fiber, an antistatic agent, a stabilizer, an anti-yellowing agent, a lubricant and the like can be retained.

[0054] The sheet-like antibacterial material 10 of the present embodiment may be dried or wet. However, the viewpoint power of reducing the corrosiveness to metals and improving the stability of iodine is preferably dry. Here, when the sheet-like antibacterial material 10 of this embodiment is wet, examples of the impregnating liquid impregnated in the sheet-like antibacterial material 10 include water, water-containing alcohol, and surfactant.

[0055] Further, the sheet-like antibacterial material 10 of the present embodiment may be a laminated type! / ヽ. Examples of the form of the laminated sheet-like antibacterial material 10 include the form shown in FIG. FIG. 2 is a cross-sectional view showing a laminated sheet-like antibacterial material. In the form shown in FIG. 2, the sheet-like antibacterial material 10 includes a first sheet-like material 10A and a second sheet-like material 10B. The first sheet-like material 10A has a configuration in which only the iodine compound (A) 14 is held on the first sheet-like substrate 12A. On the other hand, the second sheet-like material 10B has a configuration in which the iodine-based oxidizing agent (B) 16 and the acid compound (C) 18 are held on the second sheet-like base material 12B.

[0056] As shown in FIG. 2, the laminated sheet-like antibacterial material 10 in which the iodine compound (A) 14 and the iodine oxidant (B) 16 are held on separate solid substrates is used. It is preferable because it hardly exhibits iodine color before. In addition, I

3—and I

Because 5— does not exist

It is also preferable from the viewpoint that corrosion of manufacturing equipment can be prevented. However, the technical scope of the present invention is not limited only to the form in which the iodine color exhibited by the sheet-like antibacterial material 10 is thinned. The reason why the iodine color exhibited by the sheet-like antibacterial material 10 having the form shown in FIG. 2 is reduced will be described in detail in the column of the production method below. As shown in FIG. 2, when the acid compound (C) 18 is held on a solid substrate different from the iodine compound (A) 14, in other words, the iodine oxidant (B) is held. When the acid compound (C) 18 is held on the solid substrate, the iodine compound (A) power iodine (I— or I ") due to the influence of the acid compound (C)

If we can completely eliminate the possibility of generating 3 5, we will also like the viewpoint power.

Here, each sheet-like material (10A, 10B) constituting the sheet-like antibacterial material 10 having the form shown in FIG. 2 and each sheet-like substrate (12A, 12B) which is the main body of each sheet-like material are provided. Crowned The terms “first” and “second” mean that iodine-based compound 14, iodine-based oxidizing agent 16 and acid compound 18 are held on separate sheet-like substrates, respectively. It is only used for convenience to show that each sheet is composed of a separate sheet of material. Therefore, the “first” and “second” orders themselves have no special meaning. Further, the raw material of the first sheet-like base material 12A and the raw material of the second sheet-like base material 12B may be the same or different.

[0058] When the antibacterial material of the present embodiment is a sheet-like antibacterial material, the form in which each component is held on the sheet-like base material is not limited to the form shown in FIG. Can be adopted. For example, in addition to the form shown in FIG. 2, (1) the iodine compound (A) and the iodine acid oxidizing agent (B) are held on the first sheet-like substrate, and the acid compound (C) is the second compound. Form held on the sheet-like substrate; (2) Iodine-based compound (A) and acid compound (C) are held on the first sheet-like substrate, and iodine-based oxidant (B) is the second sheet. (3) Iodine compound (A) is held on the first sheet-like substrate and iodine-based oxidant (B) is held on the second sheet-like substrate. In addition, any form such as a form in which the acid compound (C) is held on the third sheet-like substrate (however, the order of stacking the first to third sheet-like substrates is not limited) It can be adopted.

[0059] Alternatively, the sheet-like antibacterial material 10 of this embodiment is further provided with a sheet other than the sheet-like antibacterial material of this embodiment on one or both sides of the sheet-like antibacterial material 10 of the form shown in FIGS. It may be a laminated sheet formed. As described above, the sheet-like antibacterial material of this embodiment may exhibit an iodine color when used. In such a case, by forming a laminated sheet laminated with another sheet, the sheet-like antibacterial material of the present embodiment exhibiting iodine color can be coated and the appearance can be improved. Even in a laminated sheet such as a cocoon, the contaminants including microorganisms attached to the surface of the stacked sheet can diffuse to the layer of the sheet-like antibacterial material of this embodiment, so that the antibacterial action can be sufficiently exerted. Further, in the sheet-like antibacterial material 10 of the form shown in FIG. 2, the sheet-like antibacterial material and the material in this embodiment are configured between the first sheet-like material 10A and the second sheet-like material 10B. Sheets other than the sheet to be performed may be further arranged. Antibacterial action can be fully exerted even in powerful laminated sheets. When the sheet-like antibacterial material of this embodiment is a laminated sheet, the sheet that can be disposed in addition to the sheet-like antibacterial material of this embodiment is particularly limited. For example, a sheet that also serves as a base material that can be used in the present embodiment can be adopted.

[0060] The method for producing the sheet-like antibacterial material 10 of the present embodiment is not particularly limited.

[0061] The sheet-like antibacterial material 10 having the form shown in FIG. 1 is prepared by, for example, preparing an immersion solution containing components to be retained, immersing the sheet-like base material 12 in the solution, taking out and drying it. It can be manufactured by a method. Hereinafter, it demonstrates in order of a process.

[0062] First, an appropriate solvent is prepared, and the above-mentioned iodine-based compound (A) 14, iodine-based oxidizing agent (B) 16, and acid compound (C) 18 are added to the prepared solvent. Prepare an immersion solution. At this time, when it is desired to hold components other than the above-mentioned components on the sheet-like base material 12, the components to be held may be added simultaneously to the dipping solution. In addition to these known additives, other additives such as stabilizers may be added for the purpose of changing the properties of the solution based on known knowledge. The solvent to be prepared is not particularly limited, and water, ethanol, methanol, toluene, ethyl acetate, acetone, tetrahydrofuran, dimethyl sulfoxide, and a mixed solvent thereof can be used. However, from the viewpoint of being able to sufficiently dissolve each of the above components, water or a solvent containing water as a main component can be preferably used.

[0063] Next, the separately prepared sheet-like substrate 12 is immersed in the immersion solution prepared above.

Thereby, each component contained in the dipping solution is held inside and on the surface of the sheet-like substrate 12. There are no particular restrictions on the specific temperature conditions when soaking and soaking time. Conventionally known knowledge can be referred to as appropriate.

[0064] After that, the sheet-like base material 12 is taken out and dried with a dipping solution force. There are no particular restrictions on the specific drying method, natural drying may be used, or forced drying by heating or blowing may be used. There are no particular restrictions on the temperature conditions and the drying time during heating, and it may be set as appropriate with reference to known knowledge.

[0065] As described above, the description has been given by taking as an example the form in which each component contained in the dipping solution is held inside and on the surface of the sheet-like base material 12 by the dipping method, but the production of the sheet-like antibacterial material 10 of this embodiment is described. It is not limited to the form of method power S. For example, any method may be employed when the solution prepared above is applied to the surface of the sheet-like substrate 12 by a method such as spray coating or roll attachment. Then, after applying the same drying process Yes. According to the strong form, the sheet-like antibacterial material 10 in a form in which each component in the solution is held on the surface of the sheet-like substrate 12 can be produced. Further, if possible, a method may be adopted in which the raw material of the sheet-like substrate 12 is further added to the above immersion solution and paper is made.

[0066] According to still another aspect of the present invention, a preferable method for producing the above-described sheet-like antibacterial material is provided. According to the manufacturing method of this embodiment, the sheet-like antibacterial material having the configuration shown in FIG. 2 can be manufactured. That is, in this embodiment, the first sheet-like substrate is immersed in a solution in which the iodine-based compound (A) is dissolved in a solvent, and the iodine-based compound (A) is added to the first sheet-like substrate. The step of holding, the second sheet-like substrate is immersed in a solution in which the iodine-based oxidizing agent (B) and the acid compound (C) are dissolved in a solvent, and the second sheet-like substrate is A step of retaining the iodine-based oxidizing agent (B) and the acid compound (C), a step of drying the first sheet-like substrate and the second sheet-like substrate, and the first sheet. And a step of laminating the second sheet-shaped substrate and the second sheet-shaped substrate. For reference, Figure 3 shows how a laminated sheet-like antibacterial material is manufactured by the manufacturing method of this embodiment.

[0067] As shown in Fig. 3, the production method of the present embodiment separately includes an immersion solution containing an iodine-based compound (A) and an immersion solution containing an iodine-based oxidizing agent (B) and an acid compound (C). Except for preparing the sheet-like antibacterial material 10 by laminating each sheet-like base material 12 by laminating each sheet-like base material 12 by immersing a separate sheet-like base material 12 in each of them, It is the same as that of said manufacturing method about the sheet-like antibacterial material of the form shown to.

[0068] As described above, the sheet-like antibacterial material 10 of the form shown in FIG. 2 produced by the production method of the present embodiment exhibits almost no iodine color before use. This is explained as follows.

[0069] That is, when an immersion solution containing all the components to be retained is prepared at a time, the reactions represented by the chemical reaction formulas (1) to (3) proceed in the immersion solution. Therefore, a certain amount of I—, I 1, and I are generated, and these are also retained in the retention process.

3 5 2

The sheet-like antibacterial material 10 exhibits a certain iodine color. In contrast, according to the manufacturing method of the present embodiment, each component to be retained does not coexist in the immersion solution at a time. Therefore, I-, I-, and I showing iodine color are not generated. For this reason, the manufacturing method of this embodiment

3 5 2

The sheet-like antibacterial material produced in this way rarely shows an iodine color before use. Therefore, according to the manufacturing method of the present embodiment, an aesthetically preferable sheet-like antibacterial material 10 can be manufactured. Furthermore, since there is no I- or I- in the manufacturing process,

3 5

From the standpoint of being able to prevent the corrosion of the.

[0070] In the manufacturing method of the present embodiment, each of the first sheet-like base material 12A and the second sheet-like base material 12B is made to hold desired components and then laminated to form a laminated sheet. Antimicrobial material 10 At this time, after each sheet-like substrate 12 is also taken out of each immersion solution force, it may be laminated before drying, and dried after lamination, or each sheet-like substrate 12 may be taken out from each immersion solution, and then each The sheet-like substrate 12 may be dried and laminated after drying. From the point of view that I-, I-, and I are not generated by the mechanism described above,

3 5 2

A laminated form can be preferably adopted.

[0071] The method of laminating when the sheet-like base materials 12 are laminated to form a laminated sheet is not particularly limited, and conventionally known methods can be appropriately employed in the field of producing laminated sheets. In selecting the lamination method, it is preferable to consider that the component held on the first sheet-like substrate 12A and the component held on the second sheet-like substrate 12B hardly react at the time of lamination. As an example of the laminating method, for example, there is a method in which the first sheet-like substrate 12A and the second sheet-like substrate are laminated to form a laminated body, and only the peripheral part of the laminated body is thermally bonded. It is done. Of course, other methods may be adopted.

[0072] The sheet-like antibacterial material 10 of the present embodiment can be applied to various uses by appropriately adjusting the amount of each component retained and the form of a solid substrate. For example, by using the sheet-shaped antibacterial material 10 of this embodiment in a compartment to which contaminants including microorganisms can adhere, the contaminant adheres to the sheet-shaped antibacterial material 10 of this embodiment, and moisture in the adhered contaminants. Iodine ions (Γ) generated by contact with iodine, iodine-based oxidants (IO_, IO-I, IO-), and

3 4

Ton (H +) produces I- and I- by the mechanism shown in the chemical reaction formulas (1) to (3) above.

Therefore, the microorganisms contained therein can be effectively sterilized. That is, an antibacterial action is exhibited.

Therefore, a specific application of the sheet-like antibacterial material 10 of the present embodiment is, for example, a toilet Laid on the floor of the toilet as a laboratory mat; laid on a laboratory table or floor as a laboratory table, and placed on a laboratory table or floor; laid on a work table or floor in a medical institution as a medical sheet; As a kitchen paper, for rugs such as laying on a kitchen workbench or floor, as a soaking sterilization sheet, for soaking in a solution contaminated by microorganisms, as a filter, Examples include filters for air conditioners, air cleaners, and vacuum cleaners, but are not limited to these. Of course, it may be used for wiping off contaminants in various places as described above.

[0079] The shape and size of the granular substrate are not particularly limited. The shape of the granular base material may be spherical, or a rectangular parallelepiped shape or an indefinite shape. Also, the size is small enough to be referred to as granular, and in addition to lumps and solids, large sizes that can give an impression can also be used as granular substrates.
