【発明の詳細な説明】 「発明の目的」 本発明は膜状素材の創案に係り、各種液体、気体の処理操作に適した比較的薄層な機能性膜状素材を提供しようとするものである。 DETAILED DESCRIPTION OF THE INVENTION "OBJECT OF THE INVENTION" The present invention relates to invented membrane-like material, various liquid, intended to provide a relatively thin layer of a functional film-like material suitable for gas processing operations is there.

(産業上の利用分野) 各種液体、気体の分離、機能的処理ないし脱気や給気などに用いられる膜材。 Various liquids (relates), separation of the gas, functional processing or degassing or air supply such as a membrane material for use in.

(従来の技術) 各種液体、気体の分離、機能的処理、脱気または散気目的において各種合成樹脂膜が採用されている。 (Prior Art) Various liquids, separation of gases, the functional process, various synthetic resin films in a degassing or aeration purposes has been adopted. 例えば電池などのセパレータとしてイオン交換樹脂膜、又セロファンなどの微孔性天然高分子フィルムやプラスチックフィルムにアクリル酸やメタクリル酸をグラフト重合させた膜などが知られている。 Such as ion exchange resin membrane, and the like microporous natural polymer film or plastic film membrane obtained by graft polymerization of acrylic acid or methacrylic acid such as cellophane is known as a separator, such as a battery. 又液体に対する散気ないし脱気に関する多孔質樹脂フィルムを用いることが行われている。 Also the use of the porous resin film is made as to an air diffuser to degassed for liquids.

更に各種フィルターとしても多孔質樹脂フィルムが用いられている。 It has been used a porous resin film as further various filters.

また各種混合液体、気体の特定成分の分離に関しても夫々の分離機能を有する樹脂膜が利用されている。 The various liquid mixture, a resin film having also a respective separation function with respect to the separation of a specific component gas is utilized.

(発明が解決しようとする問題点) 然し上記したような従来のものにおいてはなお問題点が多い。 (Invention Problems to be Solved) But still many problems in the prior art as described above. 即ちイオン交換樹脂を製膜したものは薄膜状となし、あるいは交換容量を上げたりするとその強度や液中における安定性に劣ることとなる不利がある。 That which was formed the ion exchange resin is disadvantageous to be poor in stability in a thin film shape and without, or when raising the exchange capacity thereof strength and submerged. 微孔性天然高分子フィルムによるものでは酸化剤により酸化されて劣化する傾向が大であり、プラスチックフィルムにアクリル酸などをグラフト重合させたものにおいては活物質の拡散が起ったり、腐食性に問題がある。 Is due to the microporous natural polymer film is greater tendency to degrade is oxidized by an oxidizing agent, in which the acrylic acid is graft polymerized on a plastic film or occurred diffusion of the active material, corrosive There's a problem. 更にこのような樹脂フィルムは一般的に撥水性を有し、微細化された気体粒子に種々の影響を与え、充分に均一微細で効率のよい散気目的を達し得ない。 Further, such resin film typically has a water repellency, give various effects to the miniaturized gas particles, not reach an efficient aeration purposes in a sufficiently uniform and fine.

なお疏水性多孔質樹脂フィルムを水系フィルターとして使用するときは高い透水圧の適用が必要である等の問題がある。 Note there are problems like requires the application of high magnetic pressure when using a hydrophobic porous resin film as an aqueous filter. また水分の選択的透過性が高く、耐熱性のある分離膜は極めて限られている。 The high selective permeability of moisture, the separation membrane having heat resistance is extremely limited.

「発明の構成」 (問題点を解決するための手段) ポリテトラフルオロエチレンの延伸多孔質フィルムに対し重量比で10〜30%のパーフロロ系イオン交換樹脂を均一状態に添着一体化し膜厚3〜50μmとされたことを特徴とする膜状素材。 "Configuration of the invention" (Means for Solving the Problems) polytetrafluoroethylene stretched porous film impregnated integrated into uniform state 10-30% of perfluoro-based ion exchange resin in a weight ratio with respect to the thickness 3 film-like material, characterized in that it is a 50 [mu] m.
