Examples of the inorganic compound that serves as a carrier include inorganic compound materials mainly composed of metal oxides, metal phosphates, and the like, and are particularly limited as long as they have a function capable of supporting Ag or Cu. In addition to the above, inorganic materials such as cement, gypsum, and glass-based materials are also included. Among these, as the metal-supported inorganic compound (A), since silver ions can be held firmly for a long period of time, a material obtained by supporting silver on a hardly soluble orthophosphate (for example, JP-A-5-294808, And JP-A-7-316008) can be preferably used, but is not limited thereto.

That is, only the Ag ion and Cu ion, for example, it was difficult to express a sufficient antibacterial effect against bacteria-release toxins such as verotoxin and enterotoxin, but by adding titanium dioxide to the antibacterial agent, When exposed to ultraviolet rays, a photocatalytic effect is exhibited, and the fungus-release toxin can be decomposed and detoxified. Titanium dioxide (C) is preferably in the form of fine particles generally used for photocatalysts.
前記微細可燃物（Ｄ）は、前記（Ａ）〜（Ｃ）成分とともに混練、成形した組成物を焼成した際に、焼失し、そのあとが空隙となることで、抗菌剤を多孔質体とする機能を有するものである。微細可燃物（Ｄ）としては、焼成により焼失するものであれば、特に制限されるものではないが、粉末状若しくは粒状とした合成高分子、粉末状若しくは粒状とした天然木質材、粉末状若しくは粒状とした種子、合成繊維、天然繊維、活性炭繊維などが好適に用いることができる。前記粉末状もしくは粒状とした種子としては、例えば、胡桃を粉末状若しくは粒状にしたものなどを挙げることができるが、これらに限定されるものではない。更なる高いレベルの安全性を確保し、より安心して使用するためには、天然繊維または粉末状もしくは粒状の種子などを用いることが特に好ましい。微細可燃物（Ｄ）は、抗菌剤に偏りのない空隙を生じさせて均一な多孔質体とするために、粉末状若しくは粒状又は繊維状であることが好ましい。（Ｄ）成分の粒径には特に限定はないが、５０〜５００μｍ程度であることが徐崩壊性の観点から好ましい。 The fine combustible material (D) is burned down when the composition kneaded and molded together with the components (A) to (C) is fired, and then becomes voids, so that the antibacterial agent and the porous body It has the function to do. The fine combustible material (D) is not particularly limited as long as it is burned off by firing, but is not limited to a synthetic polymer in powder form or granular form, natural wood material in powder form or granular form, powder form or Granulated seeds, synthetic fibers, natural fibers, activated carbon fibers and the like can be suitably used. Examples of the powdered or granular seeds include, but are not limited to, those in which walnuts are powdered or granular. In order to ensure a further high level of safety and to use it with more peace of mind, it is particularly preferable to use natural fibers or powdered or granular seeds. The fine combustible material (D) is preferably in the form of powder, granules, or fibers in order to create a uniform porous body by generating uniform voids in the antibacterial agent. The particle size of the component (D) is not particularly limited, but is preferably about 50 to 500 μm from the viewpoint of slow disintegration.
前記（Ａ）〜（Ｄ）成分を含有してなる組成物は、抗菌剤に求められる適度な強度と優れた抗菌性能を付与するために、各成分の混合割合を以下のような割合とする。すなわち、前記金属担持無機化合物（Ａ）は、ＡｇイオンやＣｕイオンを放出して消臭抗菌性能を発現する抗菌剤における主要成分であり、抗菌剤の単位体積当りの抗菌性能を優れたものとするために、前記組成物中に、５０〜７４重量％とする。また、前記粘土（Ｂ）は、抗菌剤の骨格を形成する成分であり、抗菌剤に求められる徐崩壊性を付与するために、前記組成物中に２０〜４４重量％とする。さらに、前記二酸化チタン（Ｃ）は、前記（Ａ）成分とともに、抗菌性能を発現する成分であり、前記組成物中に１〜１０重量％とする。また、前記微細可燃物（Ｄ）は、抗菌剤に偏りのない空隙を生じさせて多孔質体とするために、前記組成物中に５〜１０重量％とする。さらに、前記（Ａ）〜（Ｄ）成分を含有してなる組成物には、例えば、ＣＭＣ、メチルセルロースおよびアラビアガム等といったバインダー成分および水を少量加えてもよく、その添加量は、混練、成形時の取り扱い性を考慮して適宜決定すればよいが、前記バインダー成分は前記組成物中に０．５〜２重量％とするのが好ましい。 The composition comprising the components (A) to (D) has a mixing ratio of each component as described below in order to impart appropriate strength required for the antibacterial agent and excellent antibacterial performance. . That is, the metal-supported inorganic compound (A) is a main component in an antibacterial agent that releases Ag ions and Cu ions and exhibits deodorant antibacterial performance, and has excellent antibacterial performance per unit volume of the antibacterial agent. In order to do so, it is made into 50 to 74 weight% in the said composition. Moreover, the clay (B) is a component that forms a skeleton of the antibacterial agent, and is 20 to 44% by weight in the composition in order to impart the slow disintegration required for the antibacterial agent. Furthermore, the said titanium dioxide (C) is a component which expresses antibacterial performance with the said (A) component, and is 1 to 10 weight% in the said composition. Further, the fine combustible material (D) is contained in the composition in an amount of 5 to 10% by weight in order to produce a uniform void in the antibacterial agent. Furthermore, a small amount of binder components such as CMC, methylcellulose, gum arabic and the like may be added to the composition comprising the components (A) to (D), and the amount added may be kneaded or molded. The binder component may be appropriately determined in consideration of handling at the time, but the binder component is preferably 0.5 to 2% by weight in the composition.
前記（Ａ）〜（Ｄ）成分を含有してなる組成物を混練するには、一般的な混練機を用いることができる。また、混練したものを成形する際の形状は、抗菌剤の用途に応じて適宜定めればよく、特に制限されるものではないが、成形体の表面積をより大きくして水との接触面積を確保しつつ、強度も損なわないものとするために、例えば、図１（ａ）〜（ｅ）に示すような形状とすることが好ましい。例えば、図１（ａ）に示すように、両端面の略中央部に半球状の凹部を有する円柱型に成形することで、焼成前と焼成後の取り扱い時に保形力を確保でき、抗菌剤を持ち運ぶ際などに衝撃を受けるようなことがあっても、崩れにくいものにできる。また、図１（ｂ）に示すものは円筒体状であるが、このような筒状とすることで、抗菌剤の表面積が増大するうえに、図４に示し、後述するように、スプレー式容器２の吸液管５に抗菌剤３を挿着することができる。さらに、図１（ｃ）はタブレット状、（ｄ）は各面に半球状の凹部を有する四角形状、また図１（ｅ）は球状のものである。前記図１（ｅ）のように球状の抗菌剤とすることで、多数の抗菌剤を互いに接触した状態で充填して使用する場合にも、抗菌剤同士の接触による過剰な崩壊を防ぐことができる。 In order to knead the composition comprising the components (A) to (D), a general kneader can be used. Further, the shape of the kneaded product when it is molded may be appropriately determined according to the use of the antibacterial agent, and is not particularly limited, but the surface area of the molded body is increased to increase the contact area with water. In order to ensure the strength while maintaining the strength, for example, it is preferable to have a shape as shown in FIGS. For example, as shown in FIG. 1 (a), by forming a cylindrical shape having a hemispherical concave portion at the substantially central portion of both end faces, it is possible to ensure a shape retaining force during handling before and after firing, and an antibacterial agent Even if you carry a shock when carrying it, you can make it hard to collapse. Moreover, although what is shown in FIG.1 (b) is a cylindrical body shape, in addition to the surface area of an antibacterial agent increasing by making such a cylindrical shape, as shown in FIG. 4 and mentioning later, it is a spray type. The antibacterial agent 3 can be inserted into the liquid absorption tube 5 of the container 2. Further, FIG. 1C is a tablet shape, FIG. 1D is a quadrangular shape having hemispherical concave portions on each surface, and FIG. 1E is a spherical shape. By using a spherical antibacterial agent as shown in FIG. 1 (e), even when many antibacterial agents are filled and used in contact with each other, excessive collapse due to contact between the antibacterial agents can be prevented. it can.
前記（Ａ）〜（Ｄ）成分を含有してなる抗菌性組成物を混練、成形したものを焼成するときの条件としては、５００〜８００℃の雰囲気温度において２〜８時間焼成することが好ましい。ここでいう焼成とは、成形した材料に直接着火させ反応させるものではなく、炉内において高温でじっくりと処理することをいう。とくに本発明では徐崩壊性を与えるために、この温度管理に注意する必要があり、高温度、例えば９００℃以上で焼成したものは徐崩壊性を失い、また５００℃未満で焼成した時には脆くなりすぎる恐れがある。なお、前記焼成温度と焼成時間との関係は、焼成炉の熱容量との関係もあり、一概に規定することはできないが、前記温度および時間の範囲内で、焼成温度が５００℃に近くなる低い温度で焼成する場合には焼成時間を長くとり、反対に焼成温度が８００℃に近くなる高い温度で焼成する場合には焼成時間は短めにすることが、焼成後の抗菌剤の強度と崩壊性との兼ね合いの観点から好ましい。 As a condition for firing the kneaded and molded antibacterial composition containing the components (A) to (D), firing is preferably performed at an ambient temperature of 500 to 800 ° C. for 2 to 8 hours. . Firing here does not directly ignite and react the molded material, but means that the material is carefully treated at a high temperature in a furnace. In particular, in the present invention, it is necessary to pay attention to this temperature control in order to give slow disintegration, and those that are fired at a high temperature, for example, 900 ° C. or more lose their slow disintegration, and become brittle when fired at less than 500 ° C. There is a risk of too much. The relationship between the firing temperature and the firing time is also related to the heat capacity of the firing furnace, and cannot be generally specified, but within the range of the temperature and time, the firing temperature is close to 500 ° C. When firing at a temperature, the firing time should be longer, and conversely, when firing at a higher temperature where the firing temperature is close to 800 ° C., the firing time should be shorter. From the viewpoint of balance.

Furthermore, it is preferable to have a property of partially gradually disintegrating when immersed in a liquid such as water. As described above, the property of gradually disintegrating is referred to as “gradual disintegration” in the present invention. The effect of having such a property is as described later.
以上にしてなる抗菌剤は、水などの液体に浸漬したときに、超音波を照射する等といった煩雑な工程を経ることなく、その徐崩壊性により金属担持無機化合物とＴｉＯ２を液中に分散させ、更に該無機化合物からはＡｇイオンやＣｕイオンを高濃度で液中に溶出し、優れた抗菌性能を発揮できる。また、この抗菌剤は、水などに浸漬したときに、徐々に崩壊する性質を有することで、水などの溶媒のみを交換又は補充することによる繰り返し使用においても、前記金属担持無機化合物の分散や高濃度でのイオン放出性能を保持できる。 The antibacterial agent formed as described above disperses the metal-supported inorganic compound and TiO2 in the liquid due to its slow disintegration without passing through a complicated process such as irradiation with ultrasonic waves when immersed in a liquid such as water. Furthermore, Ag ions and Cu ions can be eluted from the inorganic compound at a high concentration in the liquid, and excellent antibacterial performance can be exhibited. In addition, this antibacterial agent has a property of gradually disintegrating when immersed in water or the like, so that the metal-supported inorganic compound can be dispersed or used even in repeated use by replacing or supplementing only a solvent such as water. Ion release performance at high concentration can be maintained.
また、本発明に係る抗菌液は、前記のような徐崩壊性を有する本発明の抗菌剤を、例えば水や水溶液などの液体に浸漬することにより得られる。 Further, the antibacterial liquid according to the present invention is obtained by immersing the antibacterial agent of the present invention having the above-described slow disintegration property in a liquid such as water or an aqueous solution.

前記溶液としては、ＡｇイオンまたはＣｕイオンとＴｉＯ2が存在し得るものであれば特に制限されるものではないが、前記溶液として食塩水を用いることにより、水を用いた場合と比較して、イオン濃度、特に分散した金属担持無機化合物からのＡｇイオンやＣｕイオンの溶出量を３〜５倍程度に高めることができる。食塩水を用いる場合のＮａＣｌ濃度としては、０．２５重量％以上とすることが好ましく、より好ましくは１．０重量％以上、さらに好ましくは２．０重量％以上とする。前記抗菌剤と、水などの液体との割合は、特に制限されるものではないが、例えば、図１（ａ）に示すような外径が１５ｍｍの成形体１個を、水などの液体５００ｍｌ程度に浸漬して用いることができる。 The solution is not particularly limited as long as Ag ions or Cu ions and TiO 2 can exist, but by using saline as the solution, compared to the case of using water, The ion concentration, in particular, the elution amount of Ag ions and Cu ions from the dispersed metal-supported inorganic compound can be increased to about 3 to 5 times. In the case of using a saline solution, the NaCl concentration is preferably 0.25% by weight or more, more preferably 1.0% by weight or more, and further preferably 2.0% by weight or more. The ratio between the antibacterial agent and the liquid such as water is not particularly limited. For example, one molded body having an outer diameter of 15 mm as shown in FIG. It can be used by immersing to the extent.

As the antibacterial liquid production | generation apparatus 1, it can be used by spraying the said antibacterial liquid on a target object. In addition, the antibacterial liquid has high safety by not containing an organic antibacterial agent and can be used for gargle.
本発明に係る抗菌液は、液中のＡｇイオンやＣｕイオン濃度とＴｉＯ2濃度を、高濃度とすることができるものである。このように、液中のＡｇイオンやＣｕイオンとＴｉＯ2濃度を、高濃度とすることができるのは、抗菌剤を水その他の液体に浸漬したときに徐々に崩壊し、ＡｇイオンやＣｕイオンなどの抗菌成分を含有する微粒子状の無機化合物やＴｉＯ2を液中に分散させるためである。水その他の液体に浸漬した抗菌剤が、徐々に崩壊する性質を有することは、図３に示すように、微粒子状の無機化合物３’が、抗菌液中に分散し、その一部が容器２の底２ａに堆積する現象により確認できる。ちなみに、このような徐々に崩壊する性質を有する抗菌剤を、水などの液体に浸漬してなる抗菌液は、抗菌成分が液中に拡散していくことで、該液中のＡｇイオンやＣｕイオンとＴｉＯ2濃度をより高くすることができるとともに、水などの液体のみを交換または補充することによる繰り返し使用においても高い濃度を保持でき、より製品寿命の長いものとなる。 The antibacterial liquid according to the present invention can increase the concentration of Ag ions and Cu ions and the TiO 2 concentration in the liquid. As described above, the concentration of Ag ions, Cu ions and TiO 2 in the liquid can be increased because the antibacterial agent gradually disintegrates when immersed in water or other liquid, and Ag ions or Cu ions. This is because fine inorganic compounds containing particles such as antibacterial components and TiO 2 are dispersed in the liquid. The antibacterial agent immersed in water or other liquid has the property of gradually disintegrating, as shown in FIG. 3, the fine inorganic compound 3 ′ is dispersed in the antibacterial liquid, and a part of the container 2 This can be confirmed by the phenomenon of depositing on the bottom 2a of the glass. By the way, an antibacterial liquid obtained by immersing an antibacterial agent having such a property of gradually disintegrating in a liquid such as water has an antibacterial component diffused in the liquid, so that Ag ions and Cu in the liquid The concentration of ions and TiO 2 can be increased, and a high concentration can be maintained even in repeated use by exchanging or replenishing only a liquid such as water, resulting in a longer product life.
前記スプレー式容器２を用いた抗菌液生成装置１においては、崩壊した抗菌剤成分によるノズルの目詰まりを防止するために、吸液管５の先端が容器２の底２ａより上方に位置するようにしたり、吸液管５の先端を斜に形成したりすることも好ましい実施形態である。 In the antibacterial liquid production apparatus 1 using the spray type container 2, the tip of the liquid suction pipe 5 is positioned above the bottom 2 a of the container 2 in order to prevent clogging of the nozzle due to the collapsed antibacterial agent component. It is also a preferred embodiment to make the tip of the liquid absorption pipe 5 slanted.
更に、図４に示すものは、スプレー式容器を用いた本発明にかかる抗菌液生成装置の他の実施の形態を示すものであり、図４（ａ）に示すように、スプレー式容器２の吸収管５の吸液口側先端部にフランジ部５ａを設けておき、この吸液管３に筒状の抗菌剤３を挿着したうえで、これを図５（ｂ）、（ｃ）に示すようにスプレー式容器２に装着して抗菌液生成装置１とすれば、図５（ｄ）に示すように、容器２が揺すられても抗菌剤３が容器内面に衝突して必要以上に崩壊することを防止できる。また、前記のように吸液管５に抗菌剤３を、容器内面との衝突による崩壊を防止した状態で予めスプレー容器２内にセットした製品として製造、運搬、販売に供することで、使用時には水などを容器２内に注入するだけでよく、使用者の手間がかからず簡便に使用できる。 Furthermore, what is shown in FIG. 4 shows other embodiment of the antibacterial liquid production | generation apparatus concerning this invention using the spray type container, and as shown to Fig.4 (a), of the spray type container 2 is shown. A flange portion 5a is provided at the tip of the liquid absorption port side of the absorption tube 5, and after the cylindrical antibacterial agent 3 is inserted into the liquid absorption tube 3, this is shown in FIGS. 5 (b) and 5 (c). As shown in FIG. 5 (d), the antibacterial agent 3 collides with the inner surface of the container more than necessary as shown in FIG. 5 (d). It can be prevented from collapsing. Further, as described above, the antibacterial agent 3 is applied to the liquid absorption pipe 5 as a product set in the spray container 2 in a state in which it is prevented from collapsing due to collision with the inner surface of the container. It is only necessary to inject water or the like into the container 2, and it can be used conveniently without user trouble.
また、図５に示すものは、本発明に係る抗菌液生成装置１における吸液管５の更に他の実施の形態を示すものである。この実施の形態では、スプレー式容器の吸液管５における吸液口側先端部に、放射状に外側に拡がる複数の係止片５ｂ・・・を設けたものであり、これら係止片５ｂにより、前記フランジ部５ａの場合と同様に、筒状の抗菌剤３を吸液管５に挿着し、先端に保持可能とするものである。 Moreover, what is shown in FIG. 5 shows other embodiment of the liquid absorption pipe | tube 5 in the antibacterial liquid production | generation apparatus 1 which concerns on this invention. In this embodiment, a plurality of locking pieces 5b... Radially extending outward are provided at the liquid suction port side tip of the liquid suction pipe 5 of the spray type container. As in the case of the flange portion 5a, the cylindrical antibacterial agent 3 is inserted into the liquid absorption tube 5 and can be held at the tip.
更に、図６に示すものは、スプレー式容器２を用いた抗菌液生成装置１における吸液管５の更に他の実施の形態を示すものである。この実施の形態は、吸液管３の吸液口に格子５ｃ（図６ａ参照。）を設けたり、不織布５ｄで覆う（図６ｂ参照。）ことにより、崩壊した抗菌剤のかたまりによるスプレーのノズル詰まりを防止するようにしたものである。なお、この場合、前記フランジ５ａや係止片５ｂを併設してもよいことは、いうまでもない。 Furthermore, what is shown in FIG. 6 shows still another embodiment of the liquid suction pipe 5 in the antibacterial liquid production apparatus 1 using the spray type container 2. In this embodiment, a nozzle for spraying a lump of disintegrated antibacterial agent by providing a lattice 5c (see FIG. 6a) at the liquid suction port of the liquid suction pipe 3 or covering it with a nonwoven fabric 5d (see FIG. 6b). It is designed to prevent clogging. In this case, it goes without saying that the flange 5a and the locking piece 5b may be provided side by side.
以下、実施例を挙げて本発明をさらに詳しく説明するが、本発明はこれらの実施例に何ら限定されるものではない。 EXAMPLES Hereinafter, although an Example is given and this invention is demonstrated in more detail, this invention is not limited to these Examples at all.
（１）抗菌剤の製造例１

(A), which is a material obtained by supporting 10% by weight of silver on a slightly soluble orthophosphate of two or more metals, Kibushi clay (B) 30% by weight, titanium dioxide (manufactured by Teika Co., Ltd., AMT-100) (C) 1% by weight, activated carbon powder (manufactured by Taihei Chemical Sangyo Co., Ltd., cocool SS (particle size 75-250 μm) as a fine combustible material (D) about 9% by weight) and (D) after kneading and forming into a cylindrical shape (outer diameter 15 mm, inner diameter 7 mm, height 15 mm) shown in FIG. By baking for about 2 hours at an ambient temperature of around 700 ° C., an antibacterial agent weighing about 2 g per piece was produced.
（２）抗菌性の評価
（銀イオン濃度の経時的変化）
容器に水道水５００ｍｌを入れ、さらに前記製造例で作製した抗菌剤を１個投入した時間を０時間として、２時間ごとに抗菌液を攪拌後、１０ｍｌをサンプリングして、銀イオン溶出の経時変化を測定した（ｎ数＝３）。測定は、ＩＣＰ−ＡＥＳ分光装置（「ＲＩＧＡＫＵ ＣＩＲＯＳ ＣＣＤ」、(株)リガク製）を用い、室温で行った。結果を表１に示す。
(2) Evaluation of antibacterial properties (Changes in silver ion concentration over time)
Put 500 ml of tap water in a container and add 1 antibacterial agent prepared in the above production example to 0 hour. Stir the antibacterial solution every 2 hours, sample 10 ml, and change silver ion elution over time. (N number = 3). The measurement was performed at room temperature using an ICP-AES spectrometer (“RIGAKU CIROS CCD”, manufactured by Rigaku Corporation). The results are shown in Table 1.
表１に示す通り、銀イオン濃度は、投入後２時間後には０．０８７３ｐｐｍとなり、その後も上昇を続け、１８時間後には０．２５８２ｐｐｍとなった。 As shown in Table 1, the silver ion concentration became 0.0873 ppm after 2 hours from the addition, continued to increase thereafter, and reached 0.2582 ppm after 18 hours.
（水入れ替え無し時の銀イオン濃度）
容器に水道水５００ｍｌを入れ、さらに前記製造例で作製した抗菌剤を１個投入した。水道水を入れ替えずに、１週間ごとに１０ｍｌをサンプリングして、前記と同様にして銀イオン濃度を測定した。この操作では抗菌剤として、サンプルＡおよびサンプルＢの２つそれぞれについて測定を行った。サンプルＡについての結果を表２-１に、サンプルＢについての結果を表２-２に、それぞれ示す。
(Silver ion concentration without water replacement)
500 ml of tap water was put in a container, and one antibacterial agent prepared in the above production example was further added. Without replacing the tap water, 10 ml was sampled every week, and the silver ion concentration was measured in the same manner as described above. In this operation, two samples A and B were measured as antibacterial agents. The results for sample A are shown in Table 2-1, and the results for sample B are shown in Table 2-2.
表２−１、２−２に示す通り、サンプルＡおよびサンプルＢの何れにおいても、銀イオン濃度は１週間あたり約０．３ｐｐｍづつ増加し続けた。 As shown in Tables 2-1 and 2-2, in both Sample A and Sample B, the silver ion concentration continued to increase by about 0.3 ppm per week.
（水を毎日入れ替えた時の銀イオン濃度）
容器に水道水５００ｍｌを入れ、さらに前記製造例で作製した抗菌剤を１個投入した。水道水を毎日交換し、１週間ごとに１０ｍｌをサンプリングして、前記と同様にして銀イオン濃度を測定した。この操作を抗菌剤として、サンプルＣおよびサンプルＤの２つそれぞれについて測定を行った。サンプルＣについての結果を表３-１に、サンプルＤについての結果を表３-２に、それぞれ示す。
(Silver ion concentration when water is changed daily)
500 ml of tap water was put in a container, and one antibacterial agent prepared in the above production example was further added. The tap water was changed every day, 10 ml was sampled every week, and the silver ion concentration was measured in the same manner as described above. Using this operation as an antibacterial agent, measurement was performed for each of Sample C and Sample D. The results for sample C are shown in Table 3-1, and the results for sample D are shown in Table 3-2.
表３−１、３−２に示す通り、４週間毎日、すなわち２８回交換しても、初期とほぼ同程度の濃度の銀イオンが溶出することが明らかとなった。サンプルＣおよびサンプルＤの何れにおいても、同様の結果となった。 As shown in Tables 3-1 and 3-2, it was revealed that silver ions having almost the same concentration as in the initial stage were eluted even after daily replacement for 4 weeks, that is, 28 times. Similar results were obtained for both Sample C and Sample D.
なお、以上のような銀イオンの濃度の変化は、水中における抗菌剤の徐崩壊、すなわち表面から徐々に脆くなり、徐崩壊することから、その中の無機化合物に担持された銀がイオンとして放出された結果を示し、また同時に徐崩壊によりＴｉＯ2も液中に放出され、分散される。 In addition, the change in the concentration of silver ions as described above is the slow disintegration of the antibacterial agent in water, that is, the surface gradually becomes brittle and gradually disintegrates, so that the silver supported on the inorganic compound is released as ions. At the same time, TiO 2 is also released and dispersed in the liquid by slow disintegration.
（抗菌性試験）
標準寒天培地に、（１）大腸菌（Ｅ．ｃｏｌｉ）、（２）黄色ブドウ球菌（Ｓ．ａｕｒｅｕｓ）、（３）緑膿菌（Ｐ．ｐｅｒｆｕｒｉｎｇｅｎｓ）を塗付し、前記製造例で得られた抗菌剤を水に浸漬して生成した抗菌液を１〜４回散布した。７２時間経過後に菌の増殖を観察した結果を、それぞれ図７〜図９に示す。
(Antimicrobial test)
(1) Escherichia coli (E. coli), (2) Staphylococcus aureus (S. aureus), (3) P. perfuringens were applied to a standard agar medium, and obtained in the above production example The antibacterial liquid produced by immersing the antibacterial agent in water was sprayed 1 to 4 times. The results of observing the growth of bacteria after 72 hours are shown in FIGS.
図７〜図９に示すように、大腸菌、黄色ブドウ球菌、緑膿菌の何れに対しても、抗菌液を散布することによる抗菌効果が認められた。 As shown in FIGS. 7 to 9, the antibacterial effect by spraying the antibacterial liquid was recognized against any of Escherichia coli, Staphylococcus aureus, and Pseudomonas aeruginosa.
（ＮａＣｌ添加が銀イオン濃度に及ぼす影響）
容器に水道水５００ｍｌを入れ、さらに前記製造例で作製した抗菌剤を１個投入した。２４時間後１０ｍｌをサンプリングし（ＮａＣｌ濃度０重量％）、その後ＮａＣｌ濃度１％（ほぼ生理食塩水の濃度）となるようにＮａＣｌを５ｇ加えた。ＮａＣｌ添加後２４時間目に１０ｍｌをサンプリングして、銀イオン濃度を測定した（ｎ数＝３）。結果を表４に示す。
(Effect of NaCl addition on silver ion concentration)
500 ml of tap water was put in a container, and one antibacterial agent prepared in the above production example was further added. After 24 hours, 10 ml was sampled (NaCl concentration 0% by weight), and then 5 g of NaCl was added so that the NaCl concentration became 1% (approximately the concentration of physiological saline). 10 ml was sampled 24 hours after the addition of NaCl, and the silver ion concentration was measured (n number = 3). The results are shown in Table 4.
ＮａＣｌを添加することにより、銀イオンの溶出は３〜５倍に増加することが判明した。 It was found that by adding NaCl, elution of silver ions was increased 3 to 5 times.
（ＮａＣｌ濃度が銀イオン濃度に及ぼす影響）
溶媒のＮａＣｌ濃度を種々変化させたときの、銀イオン濃度への影響を測定した結果を表５に示す。
(Effect of NaCl concentration on silver ion concentration)
Table 5 shows the results of measuring the influence on the silver ion concentration when the NaCl concentration of the solvent was changed variously.
銀イオンの溶出は、０．２５重量％のＮａＣｌ濃度下でも促進されることが明らかとなった。ＮａＣｌ濃度が、２重量％では、急激な溶出促進が見られた。 It was revealed that elution of silver ions was promoted even at a NaCl concentration of 0.25 wt%. When the NaCl concentration was 2% by weight, rapid elution enhancement was observed.
（サンプル遠心後の銀イオン濃度）
容器に水道水５００ｍｌを入れ、さらに前記製造例で作製した抗菌剤を１個投入した。さらに、ＮａＣｌ濃度が２重量％となるように、１０ｇのＮａＣｌを添加した。２４時間後にサンプリングし、４℃下、毎分１６０００回転、３０分間遠心した。結果を表６に示す。
(Silver ion concentration after sample centrifugation)
500 ml of tap water was put in a container, and one antibacterial agent prepared in the above production example was further added. Further, 10 g of NaCl was added so that the NaCl concentration was 2% by weight. The sample was sampled 24 hours later and centrifuged at 4 ° C. and 16000 rpm for 30 minutes. The results are shown in Table 6.
ＮａＣｌ存在下では、銀イオンはＡｇＣｌとなり、沈殿する可能性が考えられる。しかし、銀イオン濃度は遠心により影響を受けなかった。このことより、ＡｇＣｌとして沈殿することはないと考えられる。 In the presence of NaCl, silver ions become AgCl and may be precipitated. However, the silver ion concentration was not affected by centrifugation. From this, it is thought that it does not precipitate as AgCl.
（３）抗菌組成及び焼成条件（製造例２〜７）
前記製造例と同じ金属担持無機化合物（太平化学産業株式会社製、シルバーエース）（Ａ）、木節粘土（Ｂ）と、二酸化チタン（Ｃ）、及び活性炭粉末（Ｄ）を用い、下記表７に示す組成および焼成条件にて、前記製造例と同様にして１個あたりの重量が約２ｇとなる円柱状の抗菌剤を作製した。得られた抗菌剤をペットボトルに入れた水道水５００ｍｌ中に浸漬し、２4時間静置後、ボトルを軽く振ったのちサンプルを採取し、前記と同様にして銀イオン濃度を測定した。結果を表７に示す。
(3) Antibacterial composition and firing conditions (Production Examples 2 to 7)

The obtained antibacterial agent was immersed in 500 ml of tap water in a PET bottle, allowed to stand for 24 hours, and the bottle was shaken lightly. A sample was then taken, and the silver ion concentration was measured in the same manner as described above. The results are shown in Table 7.
表７に示すとおり、本発明の抗菌性組成物を５００〜８００℃で２〜８時間焼成することで、銀イオン放出能の高い抗菌液を生成しうる抗菌剤が得られる。 As shown in Table 7, the antibacterial agent which can produce | generate an antibacterial liquid with high silver ion release ability is obtained by baking the antibacterial composition of this invention at 500-800 degreeC for 2 to 8 hours.
