［課題を解決するための手段］
本発明は上記の目的を達成すべくなされたもので、ちっ

If it is laminated and bonded into a hob-like shape and then expanded and formed, a flat aggregate of hollow columnar cells will be formed.
z becomes a cam. By adjusting the adhesive application process and the application interval, the shape and size of the cells after molding can be controlled.
本発明においては、成形状態（展張状態）の保持をコロ
イダルシリカ系ゾルの含浸、硬化により行う。In the present invention, the molded state (stretched state) is maintained by impregnating and curing colloidal silica-based sol.

イド溶液を言い、その特性値はたとえば次の如くである
。ただしこの特性値は典型的な場合を示したものであり
、種々の変更が可能である。Colloidal silica-based sol is a transparent milky-white to milky-white colloidal solution in which ultrafine particles of silicic anhydride with a particle size of several micrometers to several tens of mB are dispersed in water (or alcohol in some cases), and its characteristic values are as follows: For example: However, this characteristic value shows a typical case, and various changes are possible.

8 to 11 or 2 to 4 Particle size near -50 Terminal viscosity + 25 eps/25°C or less Stability: 6 months to semi-permanent The amount of colloidal silica-based sol supported on the base sheet can be selected from a wide range, but 1 It is often set to about 100 g/m'', but it can also be set higher.
コロイダルシリカ系ゾルは、アルミナゾル、ケイ醜ナト
リウム水溶液などと併用することもできる。必要に応じ
骨材や硬化剤を配合してもよい。Colloidal silica-based sol can also be used in combination with alumina sol, aqueous sodium silica solution, and the like. Aggregates and hardening agents may be added as necessary.

そのままの成形状態を保持する。If a honeycomb is impregnated with colloidal silica-based Solwo 111 by spraying, coating, or infiltration, and the honeycomb is temporarily fixed in a molded state and then dried or heat-treated, the moisture will evaporate and it will harden, so the temporary fixation can be released. However, the honeycomb retains its molded state.

る。FIG. 1 is a perspective view of a main part of an example of a honeycomb for a filter according to the present invention, and FIG. 2 is a plan view thereof, in which impregnated and hardened colloidal silica sol is shown as scattered dots. FIG. 3 is a perspective view of a honeycomb before being impregnated with a colloidal silica sol. In each figure, (1) is a honeycomb in a formed state, (2) is its cells, and (3) is a cell wall.

［作 用］
本発明は、繊維質の基材シートを用いて成形されたハニ
カムを、その成形状態を保持させるためにコロイダルシ
リカ系ゾルを含浸させ、硬化させた構成よりなるので、
以下の如く作用する。[Function] The present invention has a structure in which a honeycomb formed using a fibrous base sheet is impregnated with colloidal silica-based sol and hardened in order to maintain its formed state.
It works as follows.
すなわち、き浸に用いるコロイダルシリカ系ゾルは無臭
であり、かつハニカムに含浸させた場合コロイダルシリ
カ系ゾルはハニカムの各セルを形成するセル壁面に強固
に付着し、これを乾燥または加熱処理により硬化させる
と、固いゲルを形成して皮膜化されるため、ハニカムコ
アの成形状態を強固に保持することができる。In other words, the colloidal silica-based sol used for soaking is odorless, and when impregnated into a honeycomb, the colloidal silica-based sol firmly adheres to the cell wall surface forming each cell of the honeycomb, and is hardened by drying or heat treatment. When this is done, a hard gel is formed into a film, so that the molded state of the honeycomb core can be firmly maintained.
また、含浸されたコロイダルシリカ系ゾルを硬化させる
際には、その中に含まれていた水分が空気中に放出され
るのみで臭気を発生することがないので２作業環境が損
なわれることがない上、製品の保管、輸送中などにも臭
気が発生することがない、従って、成形されたフィルタ
用のハニカムを直ちにフィルタとして用いることができ
る。In addition, when the impregnated colloidal silica-based sol is cured, the water contained in it is only released into the air and no odor is generated, so the working environment is not affected. Moreover, no odor is generated during storage or transportation of the product. Therefore, the formed honeycomb for filters can be used immediately as a filter.
ハニカムの各セル中に活性炭等の脱臭材を充填した後、
ハニカムの両面を不織布等の通気材により覆って使用す
る場合にも、充填された脱臭材の脱臭機能がハニカム自
体から発生する臭気を吸着して損なわれるおそれがない
。After filling each cell of the honeycomb with deodorizing material such as activated carbon,
Even when the honeycomb is used with both sides covered with ventilation materials such as non-woven fabrics, there is no risk that the deodorizing function of the filled deodorizing material will be impaired by adsorption of odors generated from the honeycomb itself.
