本発明は、吸放湿性に優れた吸放湿材およびそれを用い
た調湿パネルに関するものである。DETAILED DESCRIPTION OF THE INVENTION (Industrial Field of Application) The present invention relates to a moisture absorbing and releasing material with excellent moisture absorbing and releasing properties and a humidity control panel using the same.
（従来の技術）
従来より、室内や保管庫内の蒸気（湿気）を吸収し、か
つ室内等の過乾燥を放湿により防止して調湿作用を行う
吸放湿材として、木材、木質繊維板、ゾノトライト系ケ
イ酸カルシウム板等の吸放湿性を有する板材が知られて
いる。(Prior art) Wood and wood fibers have traditionally been used as moisture absorbing and desorbing materials that absorb steam (humidity) in rooms and storage areas, and prevent overdrying of indoor spaces by releasing moisture. BACKGROUND ART Board materials having moisture absorbing and releasing properties, such as boards and xonotrite calcium silicate boards, are known.
（発明が解決しようとする問題点）
しかるに、上記従来の材料は何れも、空気中の湿気を取
込んで吸着水として保持しており、雰囲気ａ度の上下変
化により吸放湿するものである。(Problems to be Solved by the Invention) However, all of the above-mentioned conventional materials absorb moisture from the air and retain it as adsorbed water, and absorb and release moisture as the atmospheric temperature changes upward and downward. .
しかも、上記材料ハ？８２Ｓｉ１度下（９５〜１０ｏ％
ＲＨ）での平衡含水率が２０〜３０％程度である。Moreover, what about the above materials? 82Si 1 degree below (95~10o%
The equilibrium water content at RH) is about 20 to 30%.
このため、常に水蒸気が発生する雰囲気中や高湿状態が
長期間に渡る雰囲気中では、その材料の吸湿の飽和点に
達するとそれ以上吸着水として取込むことができないの
で、吸湿能力がなくなりｖ１４湿することができない。For this reason, in an atmosphere where water vapor is constantly generated or where high humidity remains for a long period of time, once the moisture absorption saturation point of the material is reached, no more water can be taken in as adsorbed water, and the moisture absorption capacity is lost. Can't get wet.
一方、低湿度雰囲気中では、上記材料から吸着水を放出
して過乾燥を防ぐので、その放湿能力は上記材料の保有
水分に支配されるが、上記材料では放湿量を上げるため
に吸放湿材の厚さを増すとコストアップや重量が大とな
り取扱い性や納まりが悪くなるという問題点があった。On the other hand, in a low-humidity atmosphere, adsorbed water is released from the above materials to prevent overdrying, so the moisture release ability is controlled by the moisture retained in the materials. Increasing the thickness of the moisture-releasing material has the problem of increased cost and weight, making it difficult to handle and fit.
以上の理由により、比較的長期間高湿状態や低湿状態で
移行する雰囲気下、あるいは常に水蒸気が発生する雰囲
気下にあっては、上記従来公知の吸放湿材単独ではその
能力に限界があり不十分であった。For the above reasons, in an atmosphere where the humidity is high or low for a relatively long period of time, or in an atmosphere where water vapor is constantly generated, there is a limit to the ability of the conventionally known moisture absorbing and releasing materials alone. It was insufficient.
（発明の目的）
本発明はかかる点に鑑みてなされたものであり、上述の
如〈従来の吸放湿材単独ではその能力に限界があること
から、長期に渡って高吸敢湿性を維持し１ｑる材料を得
るとともにこの吸放湿材を中間層とし、その表裏に特定
の材料よりなる表面層及び裏面層を設けて複合パネルと
することにより、吸着水として保持し得る水分以上の水
分を取込むことができて、高湿時に多量の水分を吸収し
、低湿時にそれを放出して調湿効果を上げることができ
、しかも常に水蒸気が発生する雰囲気下にあっても連続
して吸湿し続け１ｑるようにすることを目的とする。(Purpose of the Invention) The present invention has been made in view of the above points, and as mentioned above, since there is a limit to the ability of conventional moisture absorbing and releasing materials alone, it is possible to maintain high moisture absorption properties over a long period of time. By obtaining a material with 1q of water and using this moisture absorbing/releasing material as an intermediate layer, and providing a surface layer and a back layer made of a specific material on the front and back sides of the material to form a composite panel, it is possible to absorb more moisture than can be retained as adsorbed water. It absorbs a large amount of moisture when the humidity is high and releases it when the humidity is low, increasing the humidity control effect, and it continues to absorb moisture even in an atmosphere where water vapor is constantly generated. The purpose is to continue to do so for 1q.
（問題点を解決するための手段）
この目的を達成するため、本発明の吸放湿材は、石膏１
ｏｏｔａ部に対して吸湿性フィラー３〜４０重量部を水
とともに混練硬化させてなる構成としたものである。(Means for solving the problem) In order to achieve this objective, the moisture absorbing and releasing material of the present invention
The structure is obtained by kneading and curing 3 to 40 parts by weight of a hygroscopic filler with water based on the oota part.
ざらに、本発明は、上記吸放湿材を用いたｙ４湿パネル
として、該吸放湿材の表面に透湿性材料よりなる表面材
を、裏面に微細孔を有する裏面材をそれぞれ配して一体
化してなる構成としたものである。Roughly speaking, the present invention provides a Y4 moisture panel using the above-mentioned moisture absorbing/releasing material, in which a surface material made of a moisture permeable material is disposed on the surface of the moisture absorbing/releasing material, and a back material having micropores is disposed on the back surface of the moisture absorbing/releasing material. It has an integrated structure.
（作用）
上記の構成により、本発明で得られた吸ｔｌｉ湿材およ
びその吸放湿材の表面に透湿層を、裏面に微細孔を有す
る材料を一体化したパネルを、一定温度で高湿度下に放
置すると、次の現象が生じた。(Function) With the above configuration, a panel in which a moisture-absorbing material obtained by the present invention and a material having a moisture-permeable layer on the surface of the moisture-absorbing and desorbing material and a material having micropores on the back surface are integrated is heated at a constant temperature. When left under humidity, the following phenomenon occurred.
■ 本発明の吸放湿材単独では従来のものに比べて４〜
６倍の重量増加率であったが、水の滴下はなかった。■ The moisture absorbing and desorbing material of the present invention alone has a
Although the weight increase rate was 6 times, no water dripped.
■ 透湿層（表面材）は単体で吸湿して平衡に達する以
上のｌｆｆ１となった。■ The moisture permeable layer (surface material) had an lff1 higher than that which reached equilibrium by absorbing moisture by itself.
■ 裏面材も単体で吸湿して平衡に達する以上・の重量
となった。■ The weight of the backing material was greater than that required by itself to absorb moisture and reach equilibrium.
■ 調湿パネル中層に保持された吸放湿材は吸湿初期は
ほとんど重量増加がなく、部分的に重量が減少している
ところもあった。■ There was almost no weight increase in the moisture absorbing/releasing material held in the middle layer of the humidity control panel at the initial stage of moisture absorption, and there were some areas where the weight decreased.
■ 更に高湿度下に放置しておくと裏面層から水が滴下
してきた。■ When left in high humidity conditions, water began to drip from the back layer.
以上の現象により、吸放湿材に含有された吸湿フィラー
が流出することなく石膏硬化体の微細孔に保持されてお
り、吸放湿材を中層にして一体化した場合、裏面層及び
表面層は単体で吸湿し１りる以上の水分を自由水として
科内で生じたか、あるいは取込んだことになる。Due to the above phenomenon, the hygroscopic filler contained in the hygroscopic material is retained in the fine pores of the hardened gypsum without flowing out, and when the hygroscopic material is integrated with the middle layer, the back layer and the surface layer This means that the substance absorbs moisture by itself, and more than 1 liter of water is produced or taken in as free water within the body.
この自由水の生じるメカニズムは明確でないが推察する
に、透湿層は吸放湿材が吸放湿するのを妨げないだけで
なく、高湿度下では透湿層が飽和に達してもその裏面に
ある吸放湿材が吸湿しようとするので、透湿層を通過し
ようとする蒸気が凝縮して該透湿層内で液化し自由水と
して保持されることになる。The mechanism by which this free water is generated is not clear, but it is speculated that the moisture permeable layer not only does not prevent the moisture absorbing and releasing material from absorbing and desorbing moisture, but also that under high humidity, even if the moisture permeable layer reaches saturation, its back surface Since the moisture absorbing/releasing material in the moisture absorbing layer tends to absorb moisture, the vapor that attempts to pass through the moisture permeable layer condenses and liquefies within the moisture permeable layer and is retained as free water.
また、吸放湿材の裏面層は吸放湿材より実質部の吸湿性
が小さくかつ微細孔があるので、高湿虐下では微細孔内
に湿気が飽和蒸気に近い状態で存在する一方、吸放湿材
は吸湿余力があるので、両者間に微小な蒸気圧差及び温
度差を生じ、微細孔の凝集力により液化し、微細孔内で
自由水として保持されることになる。In addition, the back layer of the moisture absorbing and releasing material has a lower hygroscopicity in the real part than the moisture absorbing and releasing material and has fine pores, so under high humidity conditions, moisture exists in the fine pores in a state close to saturated vapor. Since the moisture absorbing and releasing material has residual moisture absorption capacity, a small difference in vapor pressure and temperature is generated between the two, which is liquefied by the cohesive force of the micropores, and is retained as free water within the micropores.
更に、高湿度下に放置されると、上記微細孔内で水を保
持できなくなり、引力や吸引手段により材外に滴下され
ることとなる。尚、以上の実験では一定温魔王で行って
いるが、実用上は温喰の上下変化があるので、裏面層で
の液化は更に促進されるものと推定される。Furthermore, if left under high humidity, water cannot be retained within the micropores and will drip out of the material due to gravitational force or suction means. In addition, although the above experiment was conducted at a constant temperature, in practice there is a vertical change in the temperature, so it is presumed that the liquefaction in the back layer is further accelerated.
（実施例） 以下、本発明の実施例について説明する。(Example) Examples of the present invention will be described below.

である。The moisture absorbing and releasing material according to the present invention is prepared by mixing 3 to 40 parts by weight of a moisture absorbing and releasing filler to 100 parts by weight of gypsum, and adding 50 to 2 parts by weight of water.
By adding 00 parts, kneading, hardening and drying, 1 part is removed. The above hygroscopic filler includes calcium chloride,
Single substances or mixtures of deliquescent compounds such as magnesium chloride, lithium chloride, and sodium silicate, water-soluble polymers such as sodium isolyacrylate and PVA, and porous minerals such as seviolite and zeolite are used. Among the above-mentioned hygroscopic fillers, l#I decomposable compounds and water-soluble polymers are preferable because they have good kneadability with gypsum and water and are easily retained in the fine voids after hardening and molding.

できる。In addition, the humidity control panel of the present invention using the above-mentioned moisture absorbing and releasing material as an intermediate layer has a moisture permeable layer on the surface and a back layer having micropores on the back surface combined with the intermediate moisture absorbing and releasing material. Since it can take in more water as free water than it can hold, it absorbs more water at high humidity than the damping material alone, and quickly releases it at low humidity to control humidity. You can increase the effect. What's more, even if the panel is placed in an atmosphere where water vapor is constantly generated, moisture can be discharged from the back layer to the outside of the panel. Moisture absorption can continue.
