以下、本発明の実施の形態について、図面を参照しながら説明する。なお、この実施の形態によって本発明が限定されるものではない。 Hereinafter, embodiments of the present invention will be described with reference to the drawings. Note that the present invention is not limited to the embodiments.
(実施の形態1)
図1(a)は本発明の第1の実施の形態における脱臭体を示す外観模式図であり、(b)は脱臭体表面の拡大模式図である。脱臭体1は、担体3としてポリエチレンテレフタレートを代表とするポリエステル繊維やセルロース繊維などの有機繊維や、シリカやアルミナなどの無機繊維から構成される平板および波形板を交互に積層されたハニカム構造体であり、通気方向2へ低い通気抵抗で通気することができる。
(Embodiment 1)
Fig.1 (a) is an external appearance schematic diagram which shows the deodorizing body in the 1st Embodiment of this invention, (b) is an enlarged schematic diagram of the deodorizing body surface. The deodorizing body 1 is a honeycomb structure in which flat plates and corrugated plates made of organic fibers such as polyester fibers and cellulose fibers typified by polyethylene terephthalate as a carrier 3 and inorganic fibers such as silica and alumina are alternately laminated. Yes, it is possible to ventilate in the ventilation direction 2 with low ventilation resistance.
担体3は、触媒作用を有する酸化物4(以下、本実施の形態では触媒酸化物4という)を表面に担持する。触媒酸化物4を担体3にアンカー効果もしくは物理的な結合もしくは化学的な結合などの作用により結合させ、担持されている。 The carrier 3 supports an oxide 4 having catalytic action (hereinafter referred to as catalyst oxide 4 in the present embodiment) on the surface. The catalyst oxide 4 is supported and supported on the support 3 by an action such as an anchor effect or a physical bond or a chemical bond.
このときバインダを添加し、前記効果を高めると良いが、添加量が多い場合、吸着効果や触媒活性を低下させる原因となり、少ない場合、担体3との密着力が低下し、剥がれ落ちやすくなる。 At this time, it is preferable to add a binder to enhance the effect. However, if the addition amount is large, it may cause a decrease in the adsorption effect and catalytic activity, and if it is small, the adhesion with the carrier 3 is lowered and the film is easily peeled off.
望ましくは、触媒酸化物4とバインダとの固形分が重量比で1:1〜20:1程度である。 Desirably, the solid content of the catalyst oxide 4 and the binder is about 1: 1 to 20: 1 by weight.
また、バインダは無機系としてはナトリウムやカリウム成分を極力除去したコロイダルシリカ、リン酸アルミニウムなどが適しており、有機系としては水に酢酸ビニル、アクリル、エチレン、ビニルアルコール、変性ウレタンなどの樹脂粒子や、これらの樹脂からなる共重合樹脂粒子を分散させた水系エマルジョン型接着剤を用いるのが望ましい。 In addition, as inorganic binders, colloidal silica and aluminum phosphate from which sodium and potassium components are removed as much as possible are suitable. As organic binders, resin particles such as vinyl acetate, acrylic, ethylene, vinyl alcohol, and modified urethane are used in water. Alternatively, it is desirable to use an aqueous emulsion adhesive in which copolymer resin particles made of these resins are dispersed.
この有機系バインダは、水を蒸発させることにより、樹脂粒子や共重合樹脂粒子の濃度が高くなり、そしてこれら粒子の表面同士がくっつき始め、粒子表面が互いに溶け合い、被膜を形成することで接着作用が発揮される。 This organic binder increases the concentration of resin particles and copolymer resin particles by evaporating water, and the surfaces of these particles start to stick to each other, and the particle surfaces melt together to form a coating. Is demonstrated.
このように樹脂皮膜となるため、有機繊維に担持後も加工性に優れる一方で、無機系バインダより触媒性能は劣るという短所もある。 Thus, since it becomes a resin film, it is excellent in processability even after being supported on an organic fiber, but has a disadvantage that the catalyst performance is inferior to that of an inorganic binder.
本実施の形態では、脱臭体1に有機繊維で構成される平板および波形板を交互に積層されたハニカム構造体を用いたが、触媒酸化物4を格子状に押出成型を行ったハニカム構造
体を用いても良い。
In the present embodiment, a honeycomb structure in which flat plates and corrugated plates made of organic fibers are alternately stacked on the deodorizing body 1 is used. However, a honeycomb structure in which the catalyst oxide 4 is extruded in a lattice shape. May be used.
これにより、バインダを用いることがなくハニカム構造体全体を触媒酸化物4にすることができるので、酢酸への転化率が高い脱臭体を実現できる。 Thereby, since the whole honeycomb structure can be made into the catalyst oxide 4 without using a binder, a deodorizing body having a high conversion rate to acetic acid can be realized.
触媒酸化物4は、コバルトを主成分とする酸化物でスピネル型の結晶構造のCo3O4とすることが望ましい。 The catalyst oxide 4 is preferably an oxide containing cobalt as a main component and Co3O4 having a spinel crystal structure.
その他、Mn、Fe、Ni、Cu、Znなどの遷移金属を加え、スピネル型構造の複合酸化物としても良い。 In addition, transition metals such as Mn, Fe, Ni, Cu, and Zn may be added to form a composite oxide having a spinel structure.
これは、スピネル型構造の酸化物触媒がアセトアルデヒドを酸化し岩塩型構造となり、次に岩塩型構造が空気中の酸素により酸化されスピネル型構造に戻り、その繰り返しで触媒作用を発揮するため、スピネル型構造を選択することでアセトアルデヒドを酢酸へ転化する性能が高く、除菌・防カビ効果の高い脱臭体を実現できる。 This is because the spinel type oxide catalyst oxidizes acetaldehyde to form a rock salt type structure, and then the rock salt type structure is oxidized by oxygen in the air to return to the spinel type structure. By selecting the mold structure, it is possible to realize a deodorizing body having high performance of converting acetaldehyde into acetic acid and having high sterilizing and antifungal effects.
また、本実施の形態で用いた触媒酸化物4は0.1〜100μm程度の径であるが、この大きさに限定されるものではない。 The catalyst oxide 4 used in the present embodiment has a diameter of about 0.1 to 100 μm, but is not limited to this size.
しかしながら、大きさを小さくした方が、同体積での表面積を大きくとることができるので好ましい。 However, it is preferable to reduce the size because the surface area can be increased with the same volume.
さらに、触媒酸化物4の形も図中にあるような球状に限定されるものではなく、また実際は触媒酸化物4の一次粒子が集まり、二次粒子を形成したり、さらには三次粒子を形成したりした粒子が担体3へ担持されていると考えられる。 Further, the shape of the catalyst oxide 4 is not limited to the spherical shape as shown in the figure, and actually, the primary particles of the catalyst oxide 4 gather to form secondary particles or even tertiary particles. It is considered that the damaged particles are supported on the carrier 3.
次に担持方法について説明する。触媒酸化物4の担体3への担持方法については、スプレーなどを用いた噴霧法、ディップ法などあるが、担体3が無機繊維の場合、触媒酸化物4を必要に応じてバインダを水や溶剤などに分散させ、ハニカム構造体をそのスラリーに浸漬することで担持するディップ法が望ましい。 Next, the carrying method will be described. Examples of the method for supporting the catalyst oxide 4 on the carrier 3 include a spraying method using a spray and the dipping method. When the carrier 3 is an inorganic fiber, the catalyst oxide 4 is replaced with water or a solvent as necessary. A dipping method in which the honeycomb structure is supported by immersing the honeycomb structure in the slurry is desirable.
また担体3が有機繊維の場合、抄紙工程中に有機繊維に加えて触媒酸化物4を混合しておくことで抄紙を行い、これらを担持させることができる。 When the carrier 3 is an organic fiber, paper can be made by supporting the catalyst oxide 4 in addition to the organic fiber during the paper making process, and these can be supported.
ディップ法の場合、粉末状の触媒酸化物4とを分散させスラリーを作製するが、触媒酸化物4の平均径は小さい方が望ましく、一次粒子の平均径で1μm以下程度が望ましい。 In the case of the dip method, a powdered catalyst oxide 4 is dispersed to prepare a slurry. The average diameter of the catalyst oxide 4 is preferably small, and the average primary particle diameter is preferably about 1 μm or less.
さらには、なるべく凝集が起こらないように水や溶媒に分散させることが望ましく、必要に応じて分散剤を添加すると良い。 Furthermore, it is desirable to disperse in water or a solvent so that aggregation does not occur as much as possible, and a dispersant may be added as necessary.
ディップ法の場合、スラリーに硫酸、硝酸、塩酸、酢酸などを添加し、酸性にしておくことが望ましい。 In the case of the dip method, it is desirable to add sulfuric acid, nitric acid, hydrochloric acid, acetic acid or the like to the slurry to make it acidic.
その後、乾燥させることにより、触媒酸化物4の表面に酸が残り、それが電子の授受を速やかに行えるようにする作用があるため、触媒活性を向上させることができる。特に、硫酸で行った場合、硫酸の沸点が高いため長期間触媒酸化物4の表面上に残るため、触媒活性の高い状態を長期間維持することができる。 Thereafter, by drying, an acid remains on the surface of the catalyst oxide 4, and this has an effect of enabling quick exchange of electrons, so that the catalytic activity can be improved. In particular, when carried out with sulfuric acid, since the boiling point of sulfuric acid is high, it remains on the surface of the catalyst oxide 4 for a long period of time, so that a state of high catalytic activity can be maintained for a long period of time.
また、ディップ時ではなく、予め触媒酸化物4を酸に浸漬させ、乾燥させることで表面を酸性にしておくことも可能である。 It is also possible to make the surface acidic by dipping the catalyst oxide 4 in an acid in advance and drying it, not at the time of dipping.
このように作製した脱臭体では、空間中に存在するアセトアルデヒドを酢酸に変え、それによって脱臭体表面や脱臭体に堆積したホコリなどの除菌もしくは防カビを行うことができる。 In the deodorant produced in this way, acetaldehyde present in the space can be changed to acetic acid, whereby sterilization or mold prevention such as dust accumulated on the deodorant surface or deodorant can be performed.
(実施の形態2)
図2(a)は本発明の第2の実施の形態における脱臭体を示す外観模式図であり、(b)は脱臭体A表面の拡大模式図である。
(Embodiment 2)
FIG. 2A is a schematic external view showing a deodorizing body in the second embodiment of the present invention, and FIG. 2B is an enlarged schematic view of the surface of the deodorizing body A.
脱臭体1は、実施の形態1で用いたものと同様であり、その風下に脱臭体A5が隣接されている。 The deodorizing body 1 is the same as that used in Embodiment 1, and the deodorizing body A5 is adjacent to the leeward side.
脱臭体1と脱臭体A5とのサイズや形は異なっていてもよいし、また図2のように必ずしも密着させなくてもよい。 The size and shape of the deodorizing body 1 and the deodorizing body A5 may be different from each other, and may not necessarily be in close contact as shown in FIG.
脱臭体A5も、担体3としてポリエチレンテレフタレートを代表とするポリエステル繊維やセルロース繊維などの有機繊維や、シリカやアルミナなどの無機繊維から構成される平板および波形板を交互に積層されたハニカム構造体であり、通気方向2へ低い通気抵抗で通気することができる。 The deodorizing body A5 is also a honeycomb structure in which flat plates and corrugated plates made of organic fibers such as polyester fibers and cellulose fibers typified by polyethylene terephthalate as the carrier 3 and inorganic fibers such as silica and alumina are alternately laminated. Yes, it is possible to ventilate in the ventilation direction 2 with low ventilation resistance.
担体3は、物理吸着作用を有する吸着剤6(以下、本実施の形態では物理吸着剤6という)を表面に担持する。 The carrier 3 carries an adsorbent 6 having a physical adsorption action (hereinafter referred to as a physical adsorbent 6 in the present embodiment) on the surface.
物理吸着剤6を担体3にアンカー効果もしくは物理的な結合もしくは化学的な結合などの作用により結合させ、担持されている。 The physical adsorbent 6 is supported and supported on the carrier 3 by an action such as an anchor effect or a physical bond or a chemical bond.
このときバインダを添加し、前記効果を高めると良いが、添加量が多い場合、吸着効果や触媒活性を低下させる原因となり、少ない場合、担体3との密着力が低下し、剥がれ落ちやすくなる。 At this time, it is preferable to add a binder to enhance the effect. However, if the addition amount is large, it may cause a decrease in the adsorption effect and catalytic activity, and if it is small, the adhesion with the carrier 3 is lowered and the film is easily peeled off.
望ましくは、物理吸着剤6とバインダとの固形分が重量比で1:1〜20:1程度である。 Desirably, the solid content of the physical adsorbent 6 and the binder is about 1: 1 to 20: 1 by weight ratio.
また、バインダは無機系としてはナトリウムやカリウム成分を極力除去したコロイダルシリカ、リン酸アルミニウムなどが適しており、有機系としては水に酢酸ビニル、アクリル、エチレン、ビニルアルコール、変性ウレタンなどの樹脂粒子や、これらの樹脂からなる共重合樹脂粒子を分散させた水系エマルジョン型接着剤を用いるのが望ましい。 In addition, as inorganic binders, colloidal silica and aluminum phosphate from which sodium and potassium components are removed as much as possible are suitable. As organic binders, resin particles such as vinyl acetate, acrylic, ethylene, vinyl alcohol, and modified urethane are used in water. Alternatively, it is desirable to use an aqueous emulsion adhesive in which copolymer resin particles made of these resins are dispersed.
この有機系バインダは、水を蒸発させることにより、樹脂粒子や共重合樹脂粒子の濃度が高くなり、そしてこれら粒子の表面同士がくっつき始め、粒子表面が互いに溶け合い、被膜を形成することで接着作用が発揮される。 This organic binder increases the concentration of resin particles and copolymer resin particles by evaporating water, and the surfaces of these particles start to stick to each other, and the particle surfaces melt together to form a coating. Is demonstrated.
このように樹脂皮膜となるため、有機繊維に担持後も加工性に優れる一方で、無機系バインダより触媒性能は劣るという短所もある。 Thus, since it becomes a resin film, it is excellent in processability even after being supported on an organic fiber, but has a disadvantage that the catalyst performance is inferior to that of an inorganic binder.
本実施の形態では、脱臭体A5に有機繊維で構成される平板および波形板を交互に積層されたハニカム構造体を用いたが、物理吸着剤6を格子状に押出成型を行ったハニカム構造体を用いても良い。これにより、バインダを用いることがなくハニカム構造体全体を物理吸着剤6にすることができるので、脱臭効果の高い脱臭体を実現できる。 In the present embodiment, a honeycomb structure in which flat plates and corrugated plates made of organic fibers are alternately laminated on the deodorizing body A5 is used. However, a honeycomb structure in which the physical adsorbent 6 is extruded in a lattice shape. May be used. Thereby, since the whole honeycomb structure can be made into the physical adsorbent 6 without using a binder, a deodorizing body with a high deodorizing effect is realizable.
物理吸着剤6は、ゼオライト、シリカゲル、セピオライト、アルミナ、活性炭等の物理吸着作用を有する物質が用いられるが、臭気物質の吸脱着速度が速いゼオライトが最も望ましく、特にシリカ/アルミナ比が大きいため極性が小さい疎水性ゼオライトを用いるとよい。 As the physical adsorbent 6, a substance having a physical adsorption action such as zeolite, silica gel, sepiolite, alumina, activated carbon or the like is used. However, a zeolite having a fast adsorption / desorption rate of an odorous substance is most desirable, and the polarity is particularly large because of a large silica / alumina ratio. It is preferable to use a hydrophobic zeolite having a small particle size.
これにより、非極性の臭気分子も吸着するようになり、また雰囲気の湿度に依存することなく臭気分子を吸脱着できるため、多様な臭気分子を吸脱着できる脱臭体を実現できる。 As a result, non-polar odor molecules can be adsorbed, and the odor molecules can be adsorbed and desorbed without depending on the humidity of the atmosphere, so that a deodorant capable of adsorbing and desorbing various odor molecules can be realized.
また、ゼオライトやセピオライト等にはナトリウムやカリウム成分を極力除去したものを用いることが望ましい。 In addition, it is desirable to use zeolite or sepiolite from which sodium and potassium components are removed as much as possible.
これによりアルデヒド類からカルボン酸への転化率が向上する。 This improves the conversion rate of aldehydes to carboxylic acids.
本実施の形態で用いた疎水性ゼオライトは0.1〜100μm程度の径であるが、この大きさに限定されるものではない。 The hydrophobic zeolite used in the present embodiment has a diameter of about 0.1 to 100 μm, but is not limited to this size.
しかしながら、大きさを小さくした方が、同体積での表面積を大きくとることができるので好ましい。 However, it is preferable to reduce the size because the surface area can be increased with the same volume.
さらに、物理吸着剤6の形は図中にあるような球状に限定されるものではなく、また実際は物理吸着剤6の一次粒子が集まり、二次粒子を形成したり、さらには三次粒子を形成したりした粒子が担体3へ担持されていると考えられる。脱臭体の表面に凹凸を設けることにより、単位体積あたりの表面積を増やすことができるようになり、より効果的である。 Further, the shape of the physical adsorbent 6 is not limited to the spherical shape as shown in the figure, and actually, the primary particles of the physical adsorbent 6 gather to form secondary particles or even tertiary particles. It is considered that the damaged particles are supported on the carrier 3. By providing irregularities on the surface of the deodorizing body, the surface area per unit volume can be increased, which is more effective.
次に担持方法について説明する。物理吸着剤6の担体3への担持方法については、スプレーなどを用いた噴霧法、ディップ法などあるが、担体3が無機繊維の場合、物理吸着剤6を必要に応じてバインダを水や溶剤などに分散させ、ハニカム構造体をそのスラリーに浸漬することで担持するディップ法が望ましい。 Next, the carrying method will be described. The method for supporting the physical adsorbent 6 on the carrier 3 includes a spraying method using a spray, a dip method, and the like. When the carrier 3 is an inorganic fiber, the physical adsorbent 6 is replaced with water or a solvent as necessary. A dipping method in which the honeycomb structure is supported by immersing the honeycomb structure in the slurry is desirable.
また担体3が有機繊維の場合、抄紙工程中に有機繊維に加えて物理吸着剤6を混合しておくことで抄紙を行い、これらを担持させることができる。 In the case where the carrier 3 is an organic fiber, paper can be made and supported by mixing the physical adsorbent 6 in addition to the organic fiber during the paper making process.
ディップ法の場合、粉末状の物理吸着剤6を分散させスラリーを作製するが、物理吸着剤6の平均径は小さい方が望ましく、一次粒子の平均径で1μm以下程度が望ましい。 In the case of the dip method, a powdery physical adsorbent 6 is dispersed to produce a slurry, and the average diameter of the physical adsorbent 6 is preferably small, and the average primary particle diameter is preferably about 1 μm or less.
さらには、なるべく凝集が起こらないように水や溶媒に分散させることが望ましく、必要に応じて分散剤を添加すると良い。 Furthermore, it is desirable to disperse in water or a solvent so that aggregation does not occur as much as possible, and a dispersant may be added as necessary.
このように作製した脱臭体では、空間中に存在するアセトアルデヒドを酢酸に変え、それによって脱臭体表面や脱臭体に堆積したホコリなどの除菌もしくは防カビを行い、発生した酢酸や他の臭気を下流側に配置した脱臭体Aで除去できる脱臭体を実現できる。 In the deodorant produced in this way, the acetaldehyde present in the space is changed to acetic acid, thereby sterilizing or preventing the dust accumulated on the surface of the deodorant and the deodorant, and removing the generated acetic acid and other odors. A deodorizing body that can be removed by the deodorizing body A arranged on the downstream side can be realized.
