Description
本発明は、加湿材の抗菌・防カビ・消臭剤、それを用いた気化式加湿器、ならびに気化式加湿器の抗菌・防カビ・消臭方法に関する。 The present invention relates to an antibacterial / mold / deodorant agent for a humidifying material, a vaporizing humidifier using the same, and a method for the antibacterial / mold / deodorizing method of the vaporizing humidifier.
近年、病院や食品工場などにおけるカビや細菌による汚染が社会問題となっている。また、一般家庭、学校、事務所などでは、エアコンディショナーの普及によってカビが繁殖しやすい環境となり、カビが原因のアレルギー疾患などの問題が増えている。とりわけ、集合住宅、校舎、オフィスビル、デパート、病院、工場、倉庫、畜舎などの集中冷暖房設備を備えた施設では、１箇所で発生したカビがダクトを介して施設全域に波及するおそれがあり、カビや細菌による汚染の問題はきわめて深刻である。 In recent years, contamination by mold and bacteria in hospitals and food factories has become a social problem. In general households, schools, offices, etc., the spread of air conditioners has made it easier for molds to breed, and problems such as allergic diseases caused by molds are increasing. In particular, in facilities equipped with centralized cooling and heating equipment such as apartment houses, school buildings, office buildings, department stores, hospitals, factories, warehouses, and barns, mold generated at one place may spread throughout the facility via ducts, The problem of mold and bacteria contamination is very serious.
快適な空気調和を実現するためには、温度調整だけでなく湿度調整も求められており、さらに加湿器によって積極的に加湿することに対する要望も強い。加湿器は、方式によって、気化式加湿器、蒸気式加湿器、水噴霧式加湿器に大別されるが、気化式は、水を霧状にして放出する噴霧式に比べて、水中のカルシウムやマグネシウムなどの不純物や雑菌などを空気中に放出しない点で優れている。気化式加湿器は、ハニカム状などに形成した加湿材（以下、「加湿材」と称する。）に水を含ませておき、それに通風することで水を自然蒸発させる方式が主流である。また、気化式加湿器にもいくつかの方式があり、加湿材に毛細管現象を利用して吸水（揚水）する毛細管式と、加湿材に流水を滴下する滴下式とがあり、業務用の気化式加湿器は滴下式が主流である。図３に滴下浸透気化式加湿器の基本的実施例、図４にその側面図を示す。また本文中、「加湿モジュール」とは図３の枠を含めた「１」全体を意味し、「加湿材」とは図３の「１」内の一つ一つを意味する。 In order to realize comfortable air conditioning, not only temperature adjustment but also humidity adjustment is required, and there is a strong demand for positively humidifying with a humidifier. Humidifiers are broadly classified into vaporizing humidifiers, steam humidifiers, and water spray humidifiers, depending on the method. It is superior in that it does not release impurities such as magnesium and germs and bacteria into the air. The mainstream of vaporizing humidifiers is a method in which water is naturally evaporated by adding water to a humidifying material (hereinafter referred to as “humidifying material”) formed in a honeycomb shape or the like and ventilating it. There are also several types of vaporizing humidifiers. There are a capillary type that uses the capillary phenomenon to absorb water (pumping water) and a dripping type that drops running water on the humidifying material. As for the type humidifier, the drop type is the mainstream. FIG. 3 shows a basic example of a drop pervaporation humidifier, and FIG. 4 shows a side view thereof. In addition, in the text, “humidification module” means the entire “1” including the frame of FIG. 3, and “humidification material” means each one in “1” of FIG.
しかしながら、気化式加湿器では常に湿った状態にある加湿材の表面に細菌が繁殖し、悪臭を放つこともある。業務用で使用される気化式加湿器は、ビルの空調として用いられることが多く、空気調和機やダクトなどに取付けられるため、空気中の塵や埃あるいは浮遊細菌などが加湿材に付着し、付着した細菌が繁殖して悪臭を放つこともある。ところが気化式加湿器の加湿材を清潔に保つには手間がかかる為、衛生状態を維持するのが現実的には難しい。 However, in the vaporization type humidifier, bacteria may propagate on the surface of the humidifying material which is always in a damp state and may give off a bad odor. Vaporizing humidifiers used for business use are often used as air conditioning in buildings and are attached to air conditioners and ducts, so dust and dirt in the air or airborne bacteria adhere to the humidifier, The attached bacteria can grow and give off a foul odor. However, since it takes time to keep the humidifying material of the vaporizing humidifier clean, it is practically difficult to maintain a sanitary condition.
気化式加湿器の殺菌や抗菌技術として、加湿材の表面や内部に銀粉末や銀イオン効果が発生するような物質を含有させ、殺菌や抗菌効果を得る方式も知られている（特許文献１〜３参照）。この方式の場合は、加湿材の表面に露出した銀などとの直接的な接触により殺菌や抗菌効果を得るが、効果を示すのは直接銀イオンと接触した部分に限られてしまうため、銀粉末などの分布状況により疎らにしか存在しない箇所では効果が発揮されない。また、特に業務用で一般空調に使用されるような気化式加湿器の加湿材は、加湿運転時だけでなく、加湿運転停止時の送風状態においても加湿材がフィルター的な役割となり、常に加湿材には埃や塵、スケール分などの不純物が付着する環境下にある。銀イオン効果を有する物質を含有させた加湿材では、これらの物質の表面に埃や塵、スケール分などの不純物が付着してしまうと、加湿材に細菌が付着しても銀イオンと細菌が不純物により接触することがなくブロックされ、殺菌効果は得られないこととなる。 As a sterilization and antibacterial technique for a vaporizing humidifier, a method of obtaining a sterilization or antibacterial effect by adding a substance that generates silver powder or a silver ion effect on the surface or inside of a humidifying material is also known (Patent Document 1). To 3). In this method, sterilization and antibacterial effect are obtained by direct contact with the silver exposed on the surface of the humidifying material, but the effect is limited only to the part in direct contact with silver ions. The effect is not exhibited in places where there is only sparseness due to the distribution of powders and the like. In addition, the humidifier of vaporizer-type humidifiers that are used for general air-conditioning for commercial purposes is not only during the humidification operation but also in the air blowing state when the humidification operation is stopped. The material is in an environment where impurities such as dust, dust, and scale adhere. In humidifiers containing substances that have a silver ion effect, if impurities such as dust, dust, and scales adhere to the surface of these substances, silver ions and bacteria will not be attached even if bacteria adhere to the humidifier. It is blocked without contact with impurities, and the bactericidal effect cannot be obtained.
ポリエステル繊維とパルプを混抄する際に亜鉛系の抗菌・防カビ剤（ＺＰＴ）を含浸担持させ、乾燥して吸水性濾材を作製し、この吸水性濾材を中芯およびライナに用いてグルーパターンが蛇行状に屈曲した片面段ボールを作製し、この段ボールを裁断して積層し、加湿材を得る方式も知られている（特許文献４参照）。この方式の場合も、上記と同様、殺菌効果、持続性の点で課題がある。 When mixing polyester fiber and pulp, impregnate and support a zinc antibacterial / antifungal agent (ZPT) and dry to produce a water-absorbing filter medium. Use this water-absorbing filter medium for the core and liner to form a glue pattern. A method is also known in which a single-sided corrugated cardboard bent in a meandering manner is produced, and the corrugated cardboard is cut and laminated to obtain a humidifying material (see Patent Document 4). In the case of this method as well, there are problems in terms of bactericidal effect and sustainability.
加湿器周辺などのカビが発生しやすい場所に、ホスホリルコリン類似基含有単量体を含む単量体組成物を重合してなる重合体とビグアニド系抗菌・防カビ剤との配合物（重量比で１：１〜３０）を塗布する方式も知られている（特許文献５参照）。この方式の場合は、重合体に抗菌・防カビ剤をトラップさせるので、抗菌・防カビ剤の分布が均一状態となり、塗布面全体にカビ付着防止効果を付与できる点で優れている。しかし、実際にこの配合物を加湿材に塗布すると、給水する水に含まれているカルシウムイオンが加湿材に蓄積し、加えてビグアニド系抗菌・防カビ剤の効果を阻害するため、ヌルツキやドブ臭が発生する。 A blend of a polymer obtained by polymerizing a monomer composition containing a phosphorylcholine-like group-containing monomer and a biguanide antibacterial / antifungal agent (by weight), such as around a humidifier. A method of applying 1: 1 to 30) is also known (see Patent Document 5). In the case of this system, the antibacterial / antifungal agent is trapped in the polymer, so that the distribution of the antibacterial / antifungal agent becomes uniform and it is excellent in that the effect of preventing mold adhesion can be imparted to the entire coated surface. However, when this formulation is actually applied to a humidifying material, calcium ions contained in the water supplied will accumulate in the humidifying material, and in addition to the effects of biguanide antibacterial and antifungal agents, Odor is generated.
したがって、加湿材のように絶えず流水に接触する高親水性素材を衛生的に維持するには、抗菌・防カビ・消臭の３効果を発揮できる薬剤が望まれる。また、気化式に限らず、加湿器は、加湿材の機能が消失するまで繰返し洗浄して使用するのが通例であり、使用が長期に亘るため、薬剤効果の持続性が求められる。通常、オフィスは１，０００時間／年、工場は５，０００時間／年程度の使用を複数年継続する。さらに、加湿器の設置場所によっては、給水する水が硬水であったり、次亜塩素酸ソーダや過酸化水素などが添加されていたりすることを考慮すると、給水する水の種類を選ばずに薬剤の効果が持続することが必要である。 Therefore, in order to maintain a highly hydrophilic material that is constantly in contact with running water, such as a humidifier, in a sanitary manner, a drug that can exhibit three effects of antibacterial, antifungal, and deodorant is desired. In addition, the humidifier is not limited to the vaporizing type, and it is usual that the humidifier is repeatedly washed and used until the function of the humidifying material is lost. Usually, the office is used for 1,000 hours / year and the factory is used for about 5,000 hours / year for several years. Furthermore, depending on the installation location of the humidifier, considering that the water to be supplied is hard water or that sodium hypochlorite or hydrogen peroxide has been added, the drug can be used regardless of the type of water to be supplied. It is necessary that the effects of
本発明は、上記課題に鑑みてなされたものであり、加湿材に対する抗菌・防カビ・消臭効果を有し、かつ給水の影響を受けにくく、加湿効果を低下させることなく、抗菌・防カビ・消臭効果を長期に亘って持続させることが可能な、加湿材の抗菌・防カビ・消臭剤、および、加湿材を衛生的に維持することが可能な抗菌・防カビ・消臭方法、ならびに、気化式加湿器を提供することを目的とする。 The present invention has been made in view of the above problems, and has an antibacterial, antifungal, and deodorizing effect on a humidifying material, is hardly affected by water supply, and has an antibacterial and antifungal property without reducing the humidifying effect.・ An antibacterial / antifungal / deodorant for the humidifying material that can maintain the deodorizing effect over a long period of time, and an antibacterial / antifungal / deodorizing method that can maintain the humidifying material in a sanitary manner And it aims at providing a vaporization type humidifier.
上記課題を解決するため、本発明者らは鋭意検討を行い、加湿材にカビが発生するメカニズムは、加湿材に沈着した汚れに細菌が付着して増殖し、細菌が粘性物を代謝し、バイオフィルムとなりカビの菌床となる。経時によりカビが加湿材内部にまで繁殖し、それらの細菌やカビが悪臭を発生させることによるものと推察した。
そして、まず、細菌の付着を防止するために加湿材の表面に保水膜を形成して汚れの付きにくい表面を形成し、水の流れを利用して汚れを洗い流すようにすると共に、抗菌・防カビ剤を配合して保水膜表面で細菌やカビを殺菌することにより、従来技術では果せなかった上記課題を解決できることを見出し、本発明に到達した。
In order to solve the above problems, the present inventors have intensively studied, the mechanism that mold is generated in the humidifying material, bacteria adhere to the soil deposited on the humidifying material and proliferate, the bacteria metabolize the viscous material, It becomes a biofilm and a fungal bed of mold. It was speculated that the mold propagated to the inside of the humidifying material over time, and those bacteria and molds caused a bad odor.
First, in order to prevent the adhesion of bacteria, a moisture retaining film is formed on the surface of the humidifying material to form a surface that is difficult to get dirty. The present inventors have found that the above-mentioned problems that could not be solved by the prior art can be solved by blending a mold agent and sterilizing bacteria and mold on the surface of the water retaining film.

When the concentration is 10% by mass or less, the antibacterial / antifungal agent in the composition is It does not appear on the humidifying material surface as a foreign object.
乾燥は、６０℃〜８０℃程度の熱風乾燥を３０分以上行う方法が好ましいが、室温（２０℃）で通風しながら４８時間程度行う方法でもよい。また、使用直前に抗菌・防カビ・消臭剤を調製すれば、抗菌・防カビ・消臭剤に含まれている抗菌・防カビ剤が徐々に分解するのを抑制することができる。 The drying is preferably performed by hot air drying at about 60 ° C. to 80 ° C. for 30 minutes or more, but may be performed for about 48 hours while ventilating at room temperature (20 ° C.). In addition, if an antibacterial / antifungal / deodorant is prepared immediately before use, the antibacterial / antifungal agent contained in the antibacterial / antifungal / deodorant can be prevented from gradually decomposing.
塗工液の塗布は、加湿材素材に対する塗布量が、通常１００〜４００ｇ／ｍ２、好ましくは２００〜３００ｇ／ｍ２となるように、ロールコート方式、スプレー方式、ディップ方式、刷毛塗り方式等の公知の塗布方法により行うことができる。前記塗布量が１００ｇ／ｍ２以上であれば、所望の素材に一様に塗布できるため、十分な抗菌・防カビ・消臭効果を付与できる。一方、塗布量が４００ｇ／ｍ２以下であれば、素材の柔軟性を損なうおそれがない。 The application of the coating liquid is usually performed by a roll coating method, a spray method, a dip method, a brush coating method, or the like so that the amount applied to the humidifying material is 100 to 400 g / m 2 , preferably 200 to 300 g / m 2. It can carry out by the well-known coating method. If the coating amount is 100 g / m 2 or more, it can be applied uniformly to a desired material, and therefore sufficient antibacterial, antifungal and deodorizing effects can be imparted. On the other hand, if the coating amount is 400 g / m 2 or less, there is no possibility that the flexibility of the material is impaired.
抗菌・防カビ・消臭剤の塗布を実施するにあたっては、その前工程として、加湿材素材を公知の方法などにより洗浄処理および／または殺菌処理をしておくことが好ましい。水洗浄処理の後は殺菌処理をしておくことがより好ましい。 When applying the antibacterial / antifungal / deodorant, it is preferable that the humidifying material is cleaned and / or sterilized by a known method or the like as a pre-process. It is more preferable to perform a sterilization treatment after the water washing treatment.
洗浄処理および殺菌処理後の乾燥は、通常、乾燥温度１０〜８０℃、乾燥時間４〜２４時間の条件で、自然乾燥または強制乾燥することにより行うことができる。乾燥温度が高くなり過ぎると、素材が硬くなり吸水性が損なわれるおそれがある。 Drying after the washing treatment and the sterilization treatment can be usually performed by natural drying or forced drying under conditions of a drying temperature of 10 to 80 ° C. and a drying time of 4 to 24 hours. If the drying temperature is too high, the material becomes hard and water absorption may be impaired.

The odor of the humidifying material was evaluated in 6 stages from no odor (level 0) to strong odor (level 6).
その結果、本発明の抗菌・防カビ・消臭剤を塗布した加湿モジュールは、若干の臭気がある（レベル２）が、１シーズン交換不要であることが判った。一方、未塗布の加湿モジュールは、約１ヶ月で臭気レベル６に到達し、交換が必要であることが判った。 As a result, it was found that the humidification module to which the antibacterial / antifungal / deodorant of the present invention was applied had a slight odor (level 2), but no replacement was required for one season. On the other hand, it was found that the uncoated humidification module reached the odor level 6 in about one month and needs to be replaced.
本発明の抗菌・防カビ・消臭剤を塗布した加湿モジュールを設置した場合は、ドレン中の真菌数が１０（ｃｆｕ／ｍｌ）以下であったのに対し、未塗布の加湿モジュールを設置した場合は、ドレン中の真菌数が１０６（ｃｆｕ／ｍｌ）であった。 When the humidification module coated with the antibacterial / antifungal / deodorant of the present invention was installed, the number of fungi in the drain was 10 (cfu / ml) or less, whereas the uncoated humidification module was installed. In this case, the number of fungi in the drain was 10 6 (cfu / ml).
未塗布の加湿材を備える加湿モジュールは、加湿材に真菌が増殖し、多量のカビが付着していた。ドレンパンには茶褐色のスライムが発生していた（図２（ａ）参照）。稼動後３ヶ月で白色の付着物が見られ、半年でかなり汚染が目立つようになり、水洗いをしても使用ができない状態まで汚染が進んでいた。 In the humidification module including the unapplied humidifier, fungi grew on the humidifier, and a large amount of mold adhered. A brownish slime was generated in the drain pan (see FIG. 2A). After 3 months of operation, white deposits were seen, contamination became noticeable in half a year, and contamination progressed to a state where it could not be used even after washing with water.

Using an accumulator sprayer, the antibacterial / antifungal / deodorant prepared in Examples 1 and 2 is added to the inside of the humidifier of the humidification module (1 unit = vertical 0.8 m × width 1 m, area 0.8 m 2 ). In order to spread the liquid evenly, it was sprayed to such an extent that it was dropped from the humidifying material. Then, after heating at 60 ° C. for 30 minutes, it was dried at room temperature (20 ° C.) for about 12 hours while ventilating. A humidification module was assembled to form a vaporizing humidifier and operated for one year.
１年間稼働させた後、設置された加湿モジュールを取り外し、水道水にて加湿モジュールを洗浄した後、防カビ剤入りアルコール系除菌剤「ＡＦ１１０」により除菌し、室温（２０℃）で２時間程度乾燥させた後、実施例１〜２で調製した抗菌・防カビ・消臭剤を、加湿モジュールの加湿材より滴下する程度スプレー塗布した。その後、６０℃で３０分加温後、通風させながら室温（２０℃）で１２時間程度乾燥させた。加湿モジュールを組み立てて気化式加湿器を構成し、さらに１年間稼動させた。
After operating for one year, the installed humidification module is removed, the humidification module is washed with tap water, then sterilized with an antibacterial alcohol-based disinfectant “AF110”, and 2 at room temperature (20 ° C.). After drying for about an hour, the antibacterial / antifungal / deodorant prepared in Examples 1 and 2 was spray-applied to such an extent that it was dropped from the humidifying material of the humidifying module. Then, after heating at 60 ° C. for 30 minutes, it was dried at room temperature (20 ° C.) for about 12 hours while ventilating. A humidification module was assembled to form a vaporizing humidifier and operated for another year.
（真菌制御試験）
抗菌・防カビ・消臭剤を塗布した各加湿モジュールの表面を、滅菌綿棒を使って１００ｃｍ２ 拭き取りを行った後、滅菌綿棒をＰＤＡ培地に塗抹し、培地上に確認できた真菌数を測定した。拭き取りおよび測定は、塗布後１年稼動後、２年稼動後に行った。
(Fungus control test)
The surface of each humidification module coated with antibacterial / antifungal / deodorant was wiped 100 cm 2 using a sterile cotton swab, and then the sterile cotton swab was smeared on the PDA medium, and the number of fungi confirmed on the medium was measured. did. Wiping and measurement were performed after 1 year of operation and after 2 years of operation.
（スケール制御試験）
９個の加湿モジュールの経時による塗布面のスケール付着状態を目視で確認し、下記基準で評価した。なお、スケールの確認を容易に行えるように、加湿材を水洗いしてから確認を行った。
○：施工前と同等
△：白い付着物が確認できる
×：汚染が著しい
(Scale control test)
The scale adhesion state of the coated surface over time of the nine humidifying modules was visually confirmed and evaluated according to the following criteria. In order to easily check the scale, the humidifying material was washed with water and checked.
○: Same as before construction △: White deposits can be confirmed ×: Contamination is remarkable
比較例として、抗菌・防カビ・スケール付着防止組成物溶液を塗布していない加湿モジュールについても、上記と同様に、真菌制御試験およびスケール制御試験を行った。 As a comparative example, the fungus control test and the scale control test were performed in the same manner as described above on the humidifying module to which the antibacterial / antifungal / scale adhesion preventing composition solution was not applied.
以上の結果を表３にまとめて示す。 The above results are summarized in Table 3.
表３より、加湿モジュールは下部が比較的汚染されやすい傾向にあるものの、本発明の抗菌・防カビ・消臭剤を含浸した加湿モジュールは、極端な真菌の発育ならびにスケール付着を抑制し、長期に渡ってそれらの効果が維持されることがわかった。また、塗布面に汚れの付着が起きる場合もあったが、付着した汚れはスケール制御試験時の水洗いで全て落ちるため、２年間稼動しても稼働前とほぼ同等の状態を保持していた。
一方、未含浸（ブランク）の加湿モジュールは、稼動後１年で多量のカビが付着していた。稼動後３ヶ月で白色の付着物が見られ、半年でかなり汚染が目立つようになった。１年後は水洗いをしても使用ができない状態まで汚染が進んでいた。
From Table 3, although the humidification module tends to be relatively easily contaminated at the lower part, the humidification module impregnated with the antibacterial / antifungal / deodorant of the present invention suppresses the growth of extreme fungi and the adhesion of scales. It was found that these effects were maintained over time. In addition, although dirt adhered to the coated surface, all the adhered dirt was removed by washing with water during the scale control test, so that it remained almost the same as before operation even after two years of operation.
On the other hand, the unimpregnated (blank) humidification module had a large amount of mold attached in one year after operation. After 3 months of operation, white deposits were seen, and the contamination became noticeable in half a year. One year later, the contamination had progressed to the point where it could not be used even after washing with water.
本発明の抗菌・防カビ・消臭剤は、空調機内部で使用されている加湿材などに塗布することにより、細菌やカビの繁殖を抑制すると共に、微生物臭の防止、防汚効果を発揮するとともに、スライム付着防止性、吸水性、吸湿性、帯電防止性および防汚性を付与する機能を併せ持つので、気化式加湿装置における細菌・カビ対策として、幅広く利用可能である。 The antibacterial / antifungal / deodorant of the present invention is applied to a humidifying material used inside an air conditioner, etc. to suppress the growth of bacteria and mold, as well as to prevent microbial odor and to prevent stains. In addition, since it has functions to impart slime adhesion prevention, water absorption, moisture absorption, antistatic and antifouling properties, it can be widely used as a measure against bacteria and mold in vaporizing humidifiers.
また、バインダー樹脂が抗菌・防カビ剤を担持することにより、細菌やカビの栄養源となる汚れやＣａイオンを落としやすく、かつ抗菌・防カビ剤が加湿材素材に付着した細菌やカビの増殖を抑制するため、各種高親水性素材の表面を、常に汚れ、カルキ、カビなどが付着し難い状態に維持できる。そのため、効果が長期に亘って持続する。 In addition, the binder resin carries an antibacterial and fungicidal agent, which makes it easy to remove dirt and Ca ions, which are nutrients for bacteria and fungi, and the antibacterial and fungicidal agent grows on the humidifying material. Therefore, the surface of various highly hydrophilic materials can always be maintained in a state in which dirt, chalk, mold, etc. are difficult to adhere. Therefore, the effect lasts for a long time.
