【発明の詳細な説明】
吸湿能力を充分保持゛し、かつ対象保護物を汚染する恐
れの全く無い吸湿材の開発を鋭意研究した結果、生理的
に無害なＣＭＣ（カルボキシメチルセルロースナトリウ
ム）を素材とした吸湿材の発明に成功した。[Detailed description of the invention] As a result of intensive research into the development of a moisture absorbing material that retains sufficient moisture absorption ability and has no risk of contaminating the object to be protected, we have developed a material made from physiologically harmless CMC (sodium carboxymethylcellulose). succeeded in inventing a moisture-absorbing material.
従来ＣＭＣは吸湿性を有することが知られていたが、吸
湿剤としては専らシリカゲル、生石灰等が使用されてい
て、ＣＭＣを吸湿剤とした商品は無かった。Conventionally, CMC has been known to have hygroscopic properties, but silica gel, quicklime, etc. have been used exclusively as hygroscopic agents, and there have been no products that use CMC as a hygroscopic agent.
本発明者はＣＭＣの吸湿剤としての能力を検討した処、
吸湿速度、吸湿量に於いてもシリカゲルに劣るものでは
なく、更に自由な形に成形出来ること及び粉状で使用せ
ず、例えばフィルム状に成形しても吸湿速度が余り変ら
ないことを見出し、本発明に至った。The present inventor investigated the ability of CMC as a moisture absorbent, and found that
We discovered that it is not inferior to silica gel in terms of moisture absorption rate and amount, and that it can be molded into any shape, and that the moisture absorption rate does not change much even if it is not used in powder form, but is formed into a film, for example. This led to the present invention.
即ち、本発明はＣＭＣを主剤とする吸湿材ζＣＭＣを主
剤として平板状に成形した吸湿材及びＣＭＣ連続層を例
えば紙の如き多孔性素材でサンドウィッチにした吸湿材
である。平板状とはフィルム状、板状の意味である。That is, the present invention is a moisture absorbent material containing CMC as a main ingredient ζ A moisture absorbent material formed into a flat plate shape using CMC as a main ingredient and a CMC continuous layer sandwiched with a porous material such as paper. The term "flat" means film-like or plate-like.
ＣＭＣは生理的に無害であるので、食品添加物として認
められており、そのまま食品に接触してもさしつかえな
いが、ＣＭＣ単独の平板状物はもろいため、可塑剤を添
加する方が良い。可塑剤としては、例えばグリセリン、
プロピレングリコール等がある。又セルロース繊維を混
合して補強しても良い。又両面に紙を積層して補強して
も良い。Since CMC is physiologically harmless, it is accepted as a food additive and can be brought into contact with food as it is, but since a plate-like object made of CMC alone is brittle, it is better to add a plasticizer to it. Examples of plasticizers include glycerin,
Examples include propylene glycol. Further, it may be reinforced by mixing cellulose fibers. It may also be reinforced by laminating paper on both sides.
ＣＭＣを平板状に成形するには粉末状ＣＭＣな水で湿ら
せて熱板ではさんで乾燥させる方法でｔく、その場合紙
を両面に置けば、サンドウィッチ状のものが得られる。To form CMC into a flat plate, the powdered CMC is moistened with water and dried by sandwiching it between hot plates.In this case, by placing paper on both sides, a sandwich-like product is obtained.
実施例では両面にＪ１紙をあててサンドウィッチ状にし

ンドウィッチ状にしたものもＣＭＣのみの平板状のもの
も吸湿性能は同じであるが、サンドウィッチ状の方が強
度があって、包装材を兼ねることが出来、実用的である
。In the example, a sandwich-like structure was described in which both sides were covered with J1 paper, but the present invention is not limited to this. Both the sandwich-shaped one and the CMC-only flat plate-shaped one have the same moisture absorption performance, but the sandwich-shaped one is stronger and can double as a packaging material, making it more practical.
以下実施例によって本発明の詳細な説明する。The present invention will be explained in detail below with reference to Examples.

The moisture content of the contents after a certain period of time is determined by placing the intentionally moisture-absorbed hail and glue in a cylindrical container together with the moisture-absorbing material of the present invention (a plate-shaped molded product made by sandwiching a continuous layer of CMC with one paper), and sealing the container tightly. I looked into it. In the same way, a comparison with silica gel, which has been commonly used in the past, was also carried out. Table -
Test conditions are listed in Table 1, and test results are listed in Table 2.
