Description
本発明は、家庭用をはじめ公共施設等におけるトイレのいやな臭いを取り除くフィルター等として使用し、***臭、すなわち硫化水素、メチルメルカプタン、トリメチルアミン等の悪臭を効率的に吸着浄化するフィルターに関する。 The present invention relates to a filter that is used as a filter for removing unpleasant odors of toilets in homes and public facilities and the like and efficiently absorbs and purifies excretion odors, that is, malodors such as hydrogen sulfide, methyl mercaptan, and trimethylamine.
消臭フィルターは、様々な用途に利用されており、その消臭方法は大きく分類して活性炭やゼオライト等の吸着材を利用した吸着タイプと、オゾンや光触媒、金属フタロシアニン錯体等により悪臭物質を分解除去する触媒タイプ、あるいはこの吸着タイプと触媒タイプを併用した併用タイプに分けられる。このうち例えば、活性炭の優れた吸着作用を利用した技術がよく知られているが、これらは悪臭成分を吸着し、周辺の臭気濃度を短期的に低下させる働きには優れている。 Deodorizing filters are used in various applications. Deodorizing methods can be broadly classified into adsorption types that use adsorbents such as activated carbon and zeolite, and decomposition of malodorous substances using ozone, photocatalysts, metal phthalocyanine complexes, etc. It can be divided into a catalyst type to be removed or a combined type in which the adsorption type and the catalyst type are used in combination. Among these, for example, techniques using the excellent adsorption action of activated carbon are well known, but these are excellent in the function of adsorbing malodorous components and reducing the ambient odor concentration in the short term.
特許文献1は、病院や家庭での失禁を伴う病人の存在する環境において、消臭効果を発揮する消臭繊維を30重量%以上含む布帛からなるシート状空気清浄機用フィルターを開示している。 Patent Document 1 discloses a sheet-like air purifier filter made of a fabric containing 30% by weight or more of deodorizing fibers exhibiting a deodorizing effect in an environment where there is a sick person with incontinence at a hospital or at home. .
特許文献2は、種々の臭気成分、特にアルデヒド系ガスや低級脂肪酸等に対して効果のある、ヒドロキシアミン化合物が坦持された固体より構成される消臭フィルターを開示している。 Patent Document 2 discloses a deodorizing filter composed of a solid carrying a hydroxyamine compound, which is effective against various odor components, particularly aldehyde gases and lower fatty acids.
なお、出願人は特許文献3を出願しており、特に体臭や汗臭、あるいはペット臭、すなわちイソ吉草酸、酪酸、酢酸等の有機酸臭に大きな消臭効果があって、しかも圧力損失が低く、耐久性能の優れた有機酸臭除去フィルターを発明している。 In addition, the applicant has applied for Patent Document 3, and particularly has a great deodorizing effect on body odor, sweat odor, or pet odor, that is, organic acid odor such as isovaleric acid, butyric acid, acetic acid, etc. and pressure loss. We have invented a low organic acid odor removal filter with excellent durability.
上記技術は、消臭繊維を含む布帛からなるフィルターや固体にヒドロキシアミン化合物を坦持させたフィルターであって、アンモニア、硫化水素、メチルメルカプタン、トリメチルアミン等の悪臭に効果のある中和反応型のフィルターであるが、圧力損失が低く、耐久性に優れるトイレ臭除去フィルターが求められていた。 The above technology is a filter made of a fabric containing deodorant fibers or a filter in which a hydroxyamine compound is supported on a solid, and is a neutralization reaction type that is effective against bad odors such as ammonia, hydrogen sulfide, methyl mercaptan, and trimethylamine. Although it is a filter, a toilet odor removal filter having low pressure loss and excellent durability has been demanded.
本発明は、かかる技術的背景に鑑みてなされたものであって、家庭用をはじめ公共施設等におけるトイレのいやな臭いである***臭、すなわち硫化水素、メチルメルカプタン、トリメチルアミン等の悪臭に大きな消臭効果があって、しかも圧力損失が低く、さらに耐久性に優れるトイレ臭除去フィルターを提供することを目的とする。 The present invention has been made in view of such a technical background, and is greatly effective for excretion odor, which is an unpleasant smell of toilets in homes and other public facilities, that is, bad odors such as hydrogen sulfide, methyl mercaptan, and trimethylamine.

[1]の発明では、不織布の通気性を生かしながら、発泡剤によって発泡したバインダー樹脂を介して不織布に銅化合物を坦持した無機ケイ素化合物と、リン酸系化合物とを固着させることができる。前記不織布に銅化合物を坦持した無機ケイ素化合物が固着されているので、硫化水素、メチルメルカプタン等の***臭を無機ケイ素化合物に坦持している銅化合物との化学反応によって消臭することができる。かつ、前記不織布にリン酸系化合物が固着されているので、トリメチルアミン等の悪臭を吸着することによって消臭することができる。また、発泡剤によって発泡したバインダー樹脂を介して前記不織布に銅化合物を坦持した無機ケイ素化合物と、リン酸系化合物とを強力に固着させているので、消臭性能を持続することができる。さらに、JIS B9908規格で測定した圧力損失が、フィルターの通過風速が1.0m/秒の条件下で、フィルターの厚さ1cm当たり3〜30Paであるので例えば、家庭用をはじめ公共施設等におけるトイレのいやな臭いである***臭、すなわち硫化水素、メチルメルカプタン、トリメチルアミン等の悪臭を素早く消臭することができる。 In the invention of [1], the inorganic silicon compound carrying the copper compound on the nonwoven fabric and the phosphate compound can be fixed via the binder resin foamed by the foaming agent while taking advantage of the breathability of the nonwoven fabric. Since the inorganic silicon compound carrying the copper compound is fixed to the non-woven fabric, the excretion odor such as hydrogen sulfide and methyl mercaptan can be deodorized by a chemical reaction with the copper compound carrying the inorganic silicon compound. it can. And since the phosphoric acid type compound has adhered to the said nonwoven fabric, it can deodorize by adsorbing malodors, such as a trimethylamine. Moreover, since the inorganic silicon compound which supported the copper compound on the nonwoven fabric and the phosphoric acid compound are strongly fixed via the binder resin foamed by the foaming agent, the deodorizing performance can be maintained. Furthermore, since the pressure loss measured in accordance with JIS B9908 standard is 3 to 30 Pa per 1 cm thickness of the filter under the condition that the passing wind speed of the filter is 1.0 m / second, for example, toilets in homes and public facilities An unpleasant odor such as hydrogen sulfide, methyl mercaptan, trimethylamine and the like can be quickly eliminated.
[2]の発明では、前記バインダー樹脂がアクリル系樹脂であるので、強固に固着することができ、消臭効果の耐久性に優れたトイレ臭除去フィルターを提供できる。 In the invention of [2], since the binder resin is an acrylic resin, it is possible to provide a toilet odor removing filter that can be firmly fixed and has excellent deodorizing effect durability.
[3]の発明では、前記発泡剤がアルキルスルホン酸のアルカリ金属塩であるので、バインダー樹脂を均一に発泡することができ、しかも安定した発泡状態とすることができるので、前記不織布に銅化合物を十分均一に固着することができ、しかも通気性の低下を抑制することができる。 In the invention of [3], since the foaming agent is an alkali metal salt of an alkyl sulfonic acid, the binder resin can be uniformly foamed and a stable foamed state can be obtained. Can be sufficiently uniformly fixed, and a decrease in air permeability can be suppressed.
[4]の発明では、前記不織布に銅化合物を坦持した無機ケイ素化合物を30〜120g/m2固着しているので、硫化水素、メチルメルカプタンの悪臭を十分消臭でき、前記不織布にリン酸系化合物を30〜120g/m2固着しているので、トリメチルアミン等の悪臭を十分消臭できる。 In the invention of [4], since the inorganic silicon compound carrying a copper compound is fixed to the nonwoven fabric in an amount of 30 to 120 g / m 2 , the bad odors of hydrogen sulfide and methyl mercaptan can be sufficiently eliminated, and phosphoric acid is added to the nonwoven fabric. Since 30 to 120 g / m 2 of the compound is fixed, it is possible to sufficiently deodorize malodors such as trimethylamine.
[5]の発明では、トイレ臭除去フィルターの厚さが1〜10mmであるので、消臭性能を確保しながらかさばらず省スペースであり、しかも圧力損失が抑制されたトイレ臭除去フィルターを提供できる。 In the invention of [5], since the thickness of the toilet odor removal filter is 1 to 10 mm, it is possible to provide a toilet odor removal filter that is compact and space-saving while suppressing the deodorizing performance and that suppresses pressure loss. .

本発明の銅化合物としては、例えば銅(II)の硫酸塩、硝酸塩、ギ酸塩、シュウ酸塩などの銅化合物が挙げられるが、これら例示のものに特に限定されるものではない。これら銅化合物は、硫化水素、メチルメルカプタンの悪臭の分解に優れた効果を発揮する。 Examples of the copper compound of the present invention include copper compounds such as copper (II) sulfate, nitrate, formate, and oxalate, but are not particularly limited to these examples. These copper compounds exhibit an excellent effect in the decomposition of malodor of hydrogen sulfide and methyl mercaptan.

And in order to make a copper compound carry on an inorganic silicon compound, what is necessary is just to mix the dispersion liquid of a copper compound with the alkali salt of the said inorganic silicon compound.

本発明のトイレ臭除去フィルターの不織布は、特に限定されることなくどのようなものも使用でき、例えばケミカルボンド不織布、サーマルボンド不織布、ニードルパンチ不織布、ウォーターニードル不織布、スパンボンド不織布などが用いられ、不織布の素材は、特に限定されるものではなく、ポリエステル繊維、ポリアミド繊維、ポリプロピレン繊維、アクリル繊維等の合成繊維、あるいは、麻、綿、羊毛等の天然繊維等の繊維から構成される。なお、不織布の素材は耐久性の点で合成繊維からなるのが好ましく、必要に応じて難燃性を付与された不織布を用いても良い。 The non-woven fabric of the toilet odor removal filter of the present invention can be used without any particular limitation, for example, a chemical bond nonwoven fabric, a thermal bond nonwoven fabric, a needle punch nonwoven fabric, a water needle nonwoven fabric, a spunbond nonwoven fabric, etc. The material of the nonwoven fabric is not particularly limited, and is composed of synthetic fibers such as polyester fibers, polyamide fibers, polypropylene fibers, and acrylic fibers, or fibers such as natural fibers such as hemp, cotton, and wool. In addition, it is preferable that the raw material of a nonwoven fabric consists of a synthetic fiber from a durable point, and you may use the nonwoven fabric provided with the flame retardance as needed.
前記不織布の厚さは、1〜10mmであるのが好ましい。1mm未満では、銅化合物を坦持した無機ケイ素化合物と、トリポリリン酸アルミニウムの固着量を確保するのが難しくなるので、十分な消臭性能が得られなくなる。10mmを超えると十分な空気の通過量を確保することが難しくなり、消臭性能の低下を招くおそれがあり、またコスト的にも好ましくない。 The nonwoven fabric preferably has a thickness of 1 to 10 mm. If the thickness is less than 1 mm, it is difficult to secure the fixed amount of the inorganic silicon compound carrying the copper compound and the aluminum tripolyphosphate, so that sufficient deodorizing performance cannot be obtained. If it exceeds 10 mm, it is difficult to ensure a sufficient amount of air passing, which may cause a reduction in deodorizing performance, and is not preferable in terms of cost.
前記不織布の見掛け密度は0.01〜0.1g/cm3であるのが好ましい。0.01g/cm3未満では、銅化合物を坦持した無機ケイ素化合物と、トリポリリン酸アルミニウムの固着量を確保するのが難しくなるので、十分な消臭性能が得られなくなる。0.1g/cm3を超えると十分な空気の通過量を確保することが難しくなり、消臭性能の低下を招くおそれがあり、好ましくない。 The apparent density of the nonwoven fabric is preferably 0.01 to 0.1 g / cm 3 . If it is less than 0.01 g / cm 3 , it becomes difficult to secure the fixed amount of the inorganic silicon compound carrying the copper compound and the aluminum tripolyphosphate, so that sufficient deodorizing performance cannot be obtained. If it exceeds 0.1 g / cm 3 , it is difficult to ensure a sufficient amount of air passage, which may cause a decrease in deodorizing performance, which is not preferable.
前記不織布を構成する繊維の繊度は5〜50dtexの範囲であるものを用いるのが好ましく、5dtex未満では、通気性を確保し難く、消臭性能も低下することからも好ましくない。50dtexを超えると、銅化合物の固着量を確保するのが難しくなるので、十分な消臭性能が得られなくなる。中でも、繊度は10〜30dtexの範囲とするのがより好ましい。 The fineness of the fibers constituting the nonwoven fabric is preferably in the range of 5 to 50 dtex, and if it is less than 5 dtex, it is difficult to ensure air permeability and the deodorizing performance is also deteriorated. If it exceeds 50 dtex, it will be difficult to ensure the amount of copper compound fixed, so that sufficient deodorizing performance cannot be obtained. Among these, the fineness is more preferably in the range of 10 to 30 dtex.
銅化合物を坦持した無機ケイ素化合物の不織布への固着量は30〜120g/m2が好ましい。30g/m2を下回ると消臭性能の低下を招き、120g/m2を越えると圧力損失の増加を招くおそれがあり、好ましくない。トリポリリン酸アルミニウムの不織布への固着量は30〜120g/m2が好ましい。30g/m2を下回ると消臭性能の低下を招くおそれがあり、120g/m2を越えても圧力損失を増加させるおそれがあり、好ましくない。 The adhesion amount of the inorganic silicon compound carrying the copper compound to the nonwoven fabric is preferably 30 to 120 g / m 2 . If it is less than 30 g / m 2 , the deodorizing performance is lowered, and if it exceeds 120 g / m 2 , there is a risk of increasing pressure loss, which is not preferable. The amount of aluminum tripolyphosphate fixed to the nonwoven fabric is preferably 30 to 120 g / m 2 . If it is less than 30 g / m 2 , the deodorizing performance may be lowered, and if it exceeds 120 g / m 2 , the pressure loss may be increased, which is not preferable.
本発明で用いるバインダ−樹脂として、どのような樹脂でも使用することができる。例えば、アクリル樹脂、ウレタン樹脂、メタアクリル樹脂、シリコン樹脂、グリオキザ−ル樹脂、酢酸ビニル樹脂、塩化ビニリデン樹脂、ブタジエン樹脂、メラミン樹脂、エポキシ樹脂、アクリル−シリコン共重合体樹脂、エチレン−酢酸ビニル共重合体樹脂、イソブチレン無水マレイン酸共重合体樹脂、エチレン−スチレン−アクリレート−メタアクリレ−ト共重合体樹脂などが挙げられる。また、これらの樹脂を2種類以上混合してバインダ−樹脂としてもよい。中でも、アクリル樹脂がヒドラジド化合物と相性がよく好ましい。 Any resin can be used as the binder resin used in the present invention. For example, acrylic resin, urethane resin, methacrylic resin, silicone resin, glyoxal resin, vinyl acetate resin, vinylidene chloride resin, butadiene resin, melamine resin, epoxy resin, acrylic-silicone copolymer resin, ethylene-vinyl acetate copolymer Examples thereof include a polymer resin, an isobutylene maleic anhydride copolymer resin, and an ethylene-styrene-acrylate-methacrylate copolymer resin. Two or more of these resins may be mixed to form a binder resin. Of these, acrylic resins are preferred because of their good compatibility with hydrazide compounds.
本発明の発泡剤として、どのような発泡剤でも使用することができる。例えば、アルキルスルホン酸のアルカリ金属塩、アルキルフェノールエチレンオキシド付加物、アルキルスルホコハク酸のアルカリ金属塩などを挙げることができる。中でも、アルキルスルホン酸のアルカリ金属塩が好ましい。アルキルスルホン酸のアルカリ金属塩として、例えば、ラウリル硫酸ナトリウムを挙げることができる。 Any foaming agent can be used as the foaming agent of the present invention. For example, an alkali metal salt of alkyl sulfonic acid, an alkylphenol ethylene oxide adduct, an alkali metal salt of alkyl sulfosuccinic acid and the like can be mentioned. Of these, alkali metal salts of alkylsulfonic acid are preferable. Examples of the alkali metal salt of alkylsulfonic acid include sodium lauryl sulfate.
発泡剤によるバインダー樹脂の発泡倍率は4〜8倍にするのが好ましい。すなわち、発泡剤をバインダー樹脂に加えたのち、例えばミキサーによって、機械的に泡立てて嵩を大きくした状態で不織布に塗布するのであるが、その際の発泡倍率は4〜8倍に設定する。そうすると、バインダー樹脂が発泡されているから、少ないバインダー樹脂でありながら不織布に銅化合物を坦持した無機ケイ素化合物と、トリポリリン酸アルミニウムとを十分均一に固着することができ、しかも通気性の低下を抑制することができる。中でも、バインダー樹脂の発泡倍率は5〜7倍にするのがより好ましい。 The expansion ratio of the binder resin with the foaming agent is preferably 4 to 8 times. That is, after adding a foaming agent to binder resin, it applies to a nonwoven fabric in the state which made it foamed mechanically, for example with a mixer, and increased the volume, but the foaming ratio in that case is set to 4-8 times. As a result, since the binder resin is foamed, the inorganic silicon compound carrying the copper compound on the nonwoven fabric and the aluminum tripolyphosphate can be sufficiently uniformly fixed with a small amount of the binder resin, and the air permeability is reduced. Can be suppressed. Among these, the expansion ratio of the binder resin is more preferably 5 to 7 times.
発泡剤によって発泡したバインダー樹脂を介して不織布に銅化合物を坦持した無機ケイ素化合物と、トリポリリン酸アルミニウムとを固着させるには、例えば次のようにして固着させることができる。あらかじめ銅化合物を水に均一に分散させた銅化合物分散液を用意し、銅化合物分散液に無機ケイ素化合物を加え均一に分散させ反応させた後、吸引ろ過してから水洗・乾燥することで銅化合物を坦持した無機ケイ素化合物を得る。次に、銅化合物を坦持した無機ケイ素化合物と、トリポリリン酸アルミニウムとを水に加え均一に分散させた後、バインダー樹脂を加えた後に発泡剤を加え、例えばミキサーによって、機械的に泡立てて嵩を大きく発泡させた処理液を用意する。この処理液には、発泡させる前に分散剤などの各種添加剤を、各種特性向上のため配合してもよい。前記処理液を不織布に塗布する手段としては、特に限定されるものではないが、例えば浸漬法、コーティング法等が挙げられる。中でも、コーティング法が好ましい。 In order to fix the inorganic silicon compound supporting the copper compound on the nonwoven fabric and the aluminum tripolyphosphate through the binder resin foamed by the foaming agent, for example, the fixing can be performed as follows. Prepare a copper compound dispersion liquid in which the copper compound is uniformly dispersed in water beforehand, add the inorganic silicon compound to the copper compound dispersion liquid, uniformly disperse and react, then suction filter, wash with water and dry. An inorganic silicon compound carrying the compound is obtained. Next, an inorganic silicon compound carrying a copper compound and aluminum tripolyphosphate are added and uniformly dispersed in water, a binder resin is added, and then a foaming agent is added. Prepare a treatment liquid with a large foam. Various additives such as a dispersant may be added to the treatment liquid to improve various characteristics before foaming. The means for applying the treatment liquid to the nonwoven fabric is not particularly limited, and examples thereof include a dipping method and a coating method. Of these, the coating method is preferable.
上記のように、処理液を塗布した後に乾燥させるが、乾燥手段としては、加熱処理する方法が乾燥効率から好ましい。加熱処理温度は、100〜180℃とするのが好ましい。この温度での加熱処理によって、固着性をより高め、悪臭除去性能の持続耐久性を一層向上させることができる。 As described above, the treatment liquid is applied and then dried. As a drying means, a heat treatment method is preferable from the viewpoint of drying efficiency. The heat treatment temperature is preferably 100 to 180 ° C. By heat treatment at this temperature, it is possible to further improve the sticking property and further improve the durability of the malodor removal performance.
本発明のトイレ臭除去フィルターの圧力損失は、フィルターの厚さ1cm当たり3〜30Paである。3Pa未満では、不織布に対する銅化合物を坦持した無機ケイ素化合物と、トリポリリン酸アルミニウムの固着量を確保するのが難しくなるので、十分な消臭性能が得られなくなる。30Paを超えると十分な空気の通過量を確保することが難しくなり、消臭性能の低下を招くおそれがある。 The pressure loss of the toilet odor removal filter of the present invention is 3 to 30 Pa per 1 cm thickness of the filter. If it is less than 3 Pa, it becomes difficult to secure the fixed amount of the inorganic silicon compound carrying the copper compound to the nonwoven fabric and the aluminum tripolyphosphate, so that sufficient deodorizing performance cannot be obtained. If it exceeds 30 Pa, it will be difficult to ensure a sufficient amount of air passage, and the deodorizing performance may be reduced.
本発明のトイレ臭除去フィルターの厚さは、1〜10mmであるのが好ましい。1mm未満では、不織布に対する銅化合物を坦持した無機ケイ素化合物と、トリポリリン酸アルミニウムの固着量を確保するのが難しくなるので、十分な消臭性能が得られなくなる。10mmを超えると十分な空気の通過量を確保することが難しくなるおそれがあり、消臭性能の低下を招くおそれがあり、またコスト的にも好ましくない。 The thickness of the toilet odor removal filter of the present invention is preferably 1 to 10 mm. If the thickness is less than 1 mm, it is difficult to secure the fixed amount of the inorganic silicon compound carrying the copper compound to the nonwoven fabric and the aluminum tripolyphosphate, so that sufficient deodorizing performance cannot be obtained. If it exceeds 10 mm, it may be difficult to ensure a sufficient amount of air passage, which may cause a reduction in deodorizing performance, and is not preferable in terms of cost.
