本発明は空気清浄機等のエレメントとして用いる多孔質
ガラスペーパーに関する。DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to porous glass paper used as an element of an air cleaner or the like.
（従来の技術）
アンモニア、トリメチルアミン、硫化水素、メルカプタ
ン系等の悪臭の脱臭用素材として従来から活性炭が主流
として用いられている。この活性炭は粒状あるいは粉状
であるが、これには極微粒子がかなり含まれているため
、空気清浄機のエレメントとして用いると目詰まりを起
こす原因となる。(Prior Art) Activated carbon has conventionally been mainly used as a material for deodorizing bad odors such as ammonia, trimethylamine, hydrogen sulfide, and mercaptan. This activated carbon is in the form of granules or powder, but since it contains a considerable amount of extremely fine particles, it can cause clogging when used as an air purifier element.

叩解されたパルプ、ＰＥＴＳＰＰ、ＰＶＡ等の有機繊維
が用いられる。これらの繊維はいずれも水中で分散させ
た後、該ガラス繊維を混抄させてペーパーを形成する。Therefore, recently, porous glass fibers made from phase-splitting glass such as high-Si content soda borosilicate glass have been used instead of the activated carbon-based elements. At this time, the porous glass fiber is usually formed into a paper shape, which is then formed into a cardboard shape, and then rolled into a spiral shape to fill the resulting unit into a purifier. In order to maintain the fiber shape during shaping, appropriately beaten pulp, organic fibers such as PETSPP, and PVA are used as binders. After all of these fibers are dispersed in water, the glass fibers are mixed to form paper.
ところで前記パルプはフィブリル化によってガラス繊維

態でガラス繊維と接着一体化させるもので、ＰＥＴやＰ
Ｐの熱融着と類似している。By the way, the above-mentioned pulp is integrated with glass fibers by fibrillation, PET and PP are heated and fused after being mixed and integrated with glass fibers, and PVA is semi-dissolved and integrated with glass fibers by adhesion. So, PET and P
It is similar to thermal fusion of P.
（発明が解決しようとする課題）
ところが、前記従来の有機バインダー繊維では、次のよ

特徴とするＢＥＴ表面積や細孔容積を減殺してしまうと
いう欠点がある。That is, PET, PP, and PVA fibers cover the fine pores of porous glass fibers by means of fusion or semi-melting;
There is a drawback that the characteristic BET surface area and pore volume are reduced.
一方、ペーパーにした後に、ガラス繊維を多孔化させる

状を維持できない。On the other hand, when making glass fiber porous after making it into paper, acid treatment is inevitably performed, but at this time PET and PP
Since fibers have excellent acid resistance, they cannot be made porous as desired, and in the case of PVA, they are sensitive to acids and cannot maintain their paper shape.
これに対しパルプはフィブリル化しているので繊維同士

熱には到底耐えるものではなかった。On the other hand, since pulp is fibrillated, the paper shape can be maintained by intertwining the fibers, so synthetic pulp does not have the disadvantages of PETSPP and PVA fibers, but synthetic pulp has a low melting point, and even natural pulp has a low melting point. , the maximum temperature is about 170 to 180"C, and the paper retention time is said to be several hours. Therefore, even if the binder fiber is made of PET, PP, or PVA, or even pulp is used, When these papers are used as elements in air purifiers and are regenerated by removing moisture and adsorbed gases after long-term use, they cannot withstand the heating required.

能が損なわれない。(Function) The porous glass paper of the present invention was used by being filled in an air cleaner as an element. When air containing basic gas such as ammonia gas or cigarette smoke was passed through the purifier, the porous glass fibers in the paper suitably adsorbed the basic gas and nicotine in cigarette smoke. When the adsorption performance for gases, smoke, etc. deteriorates, the element is taken out from the purifier and heated to 180°C by appropriate heating means after dust removal.
By heating back and forth, adsorbed gas, moisture, etc. are released and regenerated. At this time, the performance of the porous glass paper is maintained despite the heating, and the heat-resistant organic fibers are not affected by heat, and the function of the porous glass fibers as a binder is not impaired.

孔質化させる方法を採用する。Porous glass fiber is produced by separating alkali borosilicate glass into a silica phase and an alkali boric acid phase through heat treatment, and eluting the alkali boric acid phase through acid treatment to form porous glass fiber. In producing the porous glass paper of the present invention, glass fibers that have already been made porous are used and mixed with fibrillated heat-resistant organic fibers. A method is adopted in which heat-treated glass fibers are used, mixed with fibrillated heat-resistant organic fibers, and then the mixed paper is subjected to acid treatment to make the glass fibers porous. .

It is preferable to use fibers with a fiber length of 3 to 12+ nm, and the blending ratio of the porous glass fiber and the heat-resistant organic fiber is:
A wide range of 9:1 to 1:9 can be adopted. In this case, of course, the smaller the ratio of the latter heat-resistant organic fibers, the better the water filtration properties, which improves the workability during production, and naturally also improves the pore properties of the resulting paper itself. In addition, during paper mixing, the side fibers are well dispersed in water, and after paper mixing, the paper is dried and, if necessary, pressed, etc., to obtain paper. Pressing in this way is preferable because higher tensile strength can be obtained. It is.
