Abstract
Description
(2)保水性高分子重合体、防カビ剤及びバインダー樹脂が添着された補強用不織布と、フィルター材とを貼り合わせてなる、上記(1)に記載の防カビエアフィルター濾材。
(3)保水性高分子重合体と防カビ剤の比率が、固形分重量比で、1:10~500である、上記(1)又は(2)に記載の防カビエアフィルター濾材。
(4)防カビ剤とバインダー樹脂の比率が、固形分重量比で、1:0.5~10である、上記(1)~(3)のいずれかに記載の防カビエアフィルター濾材。
(5)保水性高分子重合体が、下記式(1)で表される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である、上記(1)~(4)のいずれかに記載の防カビエアフィルター濾材。
(6)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が、2-(メタ)アクリロイルオキシエチル-2’-(トリメチルアンモニオ)エチルホスフェートと、ヒドロキシ基、カルボキシル基、ホスホン酸基、スルホン酸基、アミド基、アミノ基、ジアルキルアミノ基、トリアルキルアミノ塩基、トリアルキルホスホニウム塩基及びポリオキシエチレン基からなる群より選ばれる親水性基を少なくとも1つ有する親水性単量体を共重合してなる重合体である、上記(5)に記載の防カビエアフィルター濾材。
(7)親水性単量体が、トリアルキルアミノ塩基を有する親水性単量体である、上記(6)に記載の防カビエアフィルター濾材。
(8)トリアルキルアミノ塩基を有する親水性単量体が、2-ヒドロキシ-3-(メタ)アクリロイルオキシプロピルトリメチルアンモニウムクロライドである、上記(7)に記載の防カビエアフィルター濾材。

(10)上記(1)~(9)のいずれかに記載の防カビエアフィルター濾材をプリーツ状に加工したプリーツ状濾材と、該プリーツ状濾材が収納される枠体とを備えた防カビエアフィルター。
また、バインダー樹脂を添着させているため、補強用不織布(裏打ち材)を構成する繊維の種類や形状などの影響を受けることなく、バインダー樹脂の作用で、防カビ剤をより強固に添着させることができる。空調設備を稼動して空気の流れが生じても、添着した防カビ剤の脱落を防ぐことができるため、長期間に亘って防カビ効果を発揮する。
なお、本発明において「防カビ」とは、カビの発生・育成・増殖を抑制することをいい、特に製品表面のカビの増殖を抑制することをいう。また、「抗菌」とは、微生物の発生・生育・増殖を抑制することをいい、特に製品表面の細菌の増殖を抑制することをいう。
以上の「防カビ」及び「抗菌」の定義については、文献「抗菌・防カビ技術」(株式会社東レリサーチセンター調査研究部門、2004年、p22)を参考とした。
この中でも、2-(メタ)アクリロイルオキシエチル-2'-(トリメチルアンモニオ)エチルホスフェートが好ましく、さらに2-(メタクリロイルオキシ)エチル-2'-(トリメチルアンモニオ)エチルホスフェート(略称:MPC)が入手性等の点で好ましい。

防カビエアフィルター濾材1を枠体5に固定する際、補強用不織布(裏打ち材)2を、濾過する風の流れに対し上流、下流のどちら側に配置しても構わないが、補強用不織布2がごみを補足することで、防カビエアフィルター濾材1の寿命を延ばすことができる点より、濾過する風の流れに対して上流側に配置することが好ましい。
