器、温風器などに装填されて、有害ガス、有臭ガスなど
を吸着除去することにより空気を清浄化する空気浄化用
フィルターに関する。DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Field] The present invention relates to an air purification filter.
The present invention relates to an air purification filter that is installed in an air conditioner, a cooler, an air purifier, a kerosene stove, a cooler, a warmer, etc., and purifies air by adsorbing and removing harmful gases and odorous gases.
空気中に含まれる有害成分や臭気を有する成分などを
除去する目的で、エアコン、クーラーなどに空気浄化用
フィルターが用いられている。Air purifying filters are used in air conditioners, coolers, and the like for the purpose of removing harmful components and odorous components contained in the air.
従来の空気浄化用フィルターにおいては、スポンジに
活性炭を含浸させたものや、活性炭ハニカム、活性炭繊
維紙コルゲートなどが吸着材として用いられていた。In a conventional air purification filter, a sponge impregnated with activated carbon, an activated carbon honeycomb, an activated carbon fiber paper corrugate, or the like has been used as an adsorbent.
〔発明が解決しようとする課題〕 ところで、空気浄化用フィルターとしては、吸着能力
が大きくて、圧力損失（以下、「圧損」という）の小さ
いものが好ましい。[Problems to be Solved by the Invention] As the air purification filter, a filter having a large adsorption capacity and a small pressure loss (hereinafter, referred to as “pressure loss”) is preferable.
しかしながら、従来においてはかかる理想的なフィル

用いた、従来のフィルターの活性炭含有量および圧損を
示したものであり、同表に示すように、活性炭含有量が
少ないもの、或いは、圧損が大きいものしか存在しなか
った。However, such an ideal filter has not been obtained conventionally. The table shows the activated carbon content and pressure loss of a conventional filter using activated carbon powder as an adsorbent.As shown in the table, only those having a low activated carbon content or those having a large pressure loss exist. Did not.
活性炭含有量が多いフィルター（表中、500セルおよ

ィルターの寿命が長く、この点では好ましいものの、圧
損が0.90以上と大きい。このため、装置を駆動するため
に大きなファン動力を必要とし、運転音が大きいなどの
問題があった。 Filters with a high content of activated carbon (honeycomb with 500 cells and 300 cells in the table) have a large adsorption capacity and therefore a long filter life, which is preferable in this respect, but has a large pressure loss of 0.90 or more. For this reason, there has been a problem that a large fan power is required to drive the device, and the operation noise is loud.
一方、圧損が比較的小さいフィルター（表中、HR−08
（ブリジストン社製、商品コード）、HR−10（同）、コ
ルゲート）は、活性炭含有量が少ない。このため、吸着
能力が小さいとともに、フィルター寿命が短いためフィ
ルター交換を頻繁に行う必要があるという問題があっ
た。On the other hand, a filter with a relatively small pressure loss (HR-08 in the table)
(Bridgestone, product code), HR-10 (same as above, corrugate) have low activated carbon content. Therefore, there is a problem that the adsorption capacity is small and the filter life is short, so that the filter needs to be frequently replaced.
なお、活性炭含有量を多くするために活性炭粉末に代
えて、粒状活性炭を用いることも考えられるが、それで
は圧損が大きくなってしまう。In order to increase the content of activated carbon, it is conceivable to use granular activated carbon instead of activated carbon powder, but this increases the pressure loss.
また、スポンジシートに活性炭を添着したものもある
が、添着量に限界があるため、活性炭含有量の多いフィ
ルターを得ることはできない。Some sponge sheets have activated carbon impregnated. However, since the amount of impregnation is limited, a filter having a high activated carbon content cannot be obtained.
表中の活性炭コルゲートは、穴を小径化することによ
り活性炭含有量を多くすることができるものの、そうす
ると目詰まりが起きて圧損が大きくなってしまうという
問題が生じる。Activated carbon corrugates in the table can increase the content of activated carbon by reducing the diameter of the hole, but this causes a problem that clogging occurs and pressure loss increases.
本発明は以上の事情に鑑みなされたものであって、そ
の目的とするところは、フィルター寿命が長く、しかも
圧損の小さい、優れた吸着能力を有する空気浄化用フィ
ルターを提供するにある。The present invention has been made in view of the above circumstances, and it is an object of the present invention to provide an air purification filter having a long filter life, a small pressure loss, and an excellent adsorption capacity.
本発明の空気浄化用フィルターは上記の課題を達成す

粒子からなる配合物に、ガラス繊維を加えて前記と同様
に作製したフィルターも本発明に含まれている。The air purification filter of the present invention has been developed in order to achieve the above object, and is a blend of 100 parts by weight of activated carbon fine particles and a thermoplastic resin or mesoface pitch fine particle in an amount not exceeding 50 parts by weight. Thickness formed by heating and pressing molding method is 0.1mm or more, and 3mm
A filter characterized in that strip-shaped adsorbent elements obtained by cutting the following sheet-shaped molded body are loaded in a state of being arranged in parallel with each other. Further, the present invention also includes a filter prepared by adding glass fibers to a blend comprising the above-mentioned activated carbon fine particles and thermoplastic resin or mesoface pitch fine particles in the same manner as described above.
本発明の空気浄化用フィルターに使用する吸着剤には
活性炭の微粒子を使用する必要がある。活性炭微粒子は
生活空間に含まれる殆どの有害成分や悪臭を有する成分
を吸着・除去する能力が優れている。It is necessary to use fine particles of activated carbon as the adsorbent used in the air purification filter of the present invention. Activated carbon fine particles have excellent ability to adsorb and remove most harmful components and components having bad odors contained in the living space.
活性炭微粒子の粒度は、特に限定しないが、通常１μ
mm〜0.3mm程度の粒径の微粒子が好ましい。The particle size of the activated carbon fine particles is not particularly limited, but is usually 1 μm.
Fine particles having a particle diameter of about mm to 0.3 mm are preferred.
本発明で使用される熱可塑性樹脂は特に限定しない
が、例えば、ポリエチレン、ポリプロピレン、ABS、PE
T、ナイロン、PBT、エチレンアクリル樹脂、PMMA樹脂等

フェースピッチも使用できる。The thermoplastic resin used in the present invention is not particularly limited, for example, polyethylene, polypropylene, ABS, PE
Fine particles such as T, nylon, PBT, ethylene acrylic resin, and PMMA resin can be used. Mesoface pitch other than thermoplastic resin can also be used.
本発明においては、活性炭微粒子100重量部に対し
て、50重量部を越えない量の熱可塑性樹脂またはメソフ
ェースピッチの微粒子を用いる必要がある。50重量部を
越えた場合、活性炭含有量の減少による吸着能の低下が
生じるからである。活性炭微粒子の粒度や比重によって
異なるが、通常２〜50重量部の熱可塑性樹脂等を用いる
ことが好ましい。成形体が破損、破壊しない程度の必要
最小限の熱可塑性樹脂等を用いることが活性炭の含有率
を高くする意味からより好ましい。In the present invention, it is necessary to use thermoplastic resin or mesoface pitch fine particles in an amount not exceeding 50 parts by weight based on 100 parts by weight of activated carbon fine particles. If the amount exceeds 50 parts by weight, the adsorptivity will decrease due to the decrease in the activated carbon content. Although it depends on the particle size and specific gravity of the activated carbon fine particles, it is usually preferable to use 2 to 50 parts by weight of a thermoplastic resin or the like. From the viewpoint of increasing the content of activated carbon, it is more preferable to use a minimum necessary thermoplastic resin or the like that does not break or break the molded body.
本発明に用いるシート状成形体のシート厚は0.1mm以
上であり、且つ、3mm以下である必要がある。これはシ
ート厚が0.1mm以下の場合、シート状成形体の強度が低
く、フィルター枠に装填することが困難になるからであ
り、またシート厚が3mm以上である場合、圧損が大きく
なり空気の流通速度が低下するため、活性炭含有量が多
いにもかかわらず、吸着速度が高いフィルターを得るこ
とが困難になるからである。The sheet thickness of the sheet-shaped molding used in the present invention needs to be 0.1 mm or more and 3 mm or less. This is because when the sheet thickness is 0.1 mm or less, the strength of the sheet-like molded body is low, and it becomes difficult to load the filter into the filter frame.When the sheet thickness is 3 mm or more, the pressure loss increases and air This is because, since the flow rate is reduced, it is difficult to obtain a filter having a high adsorption rate despite a large content of activated carbon.
次に、本発明に係る空気浄化用フィルターの製造方法

高周波等を照射したりする方法がある。The activated carbon fine particles and the fine particles of a thermoplastic resin or the like can be adhered to each other only by mixing. However, in order to further strengthen the adhesion between the two and prevent the particles from falling off, it is preferable to heat and mix. Examples of the heating method in this case include applying static electricity, microwaves, infrared rays, far infrared rays,
There is a method of irradiating a high frequency or the like.

形するおそれはない。Next, the above-mentioned composition was formed into a sheet, and the sheet thickness was 0.1 mm.
A sheet-shaped molded product of about 3 mm is produced. In the sheet forming, various conventionally known pressure forming machines such as a dry press, a roll press, a belt press, a doctor blade and the like can be used. Here, the heating temperature at the time of the above-mentioned heating and pressure molding is in the range of softening to melting temperature of the thermoplastic resin, and is much lower than the softening and melting temperature of glass fiber. Therefore, there is no possibility that the shape of the glass fiber contained in the molded body is deformed.

Since the amount is large, harmful components and components having an odor in the air are efficiently removed.
