Description

本発明は、電子部品や有機エレクトロルミネセンス素子など乾燥環境を必要とする内容物を収納する容器内に、在中させて使用する瞬発性を有する高機能乾燥剤シートに関するもである。   The present invention relates to a highly functional desiccant sheet having a flashing property that is used in a container that stores contents that require a dry environment, such as electronic components and organic electroluminescent elements.

従来、乾燥環境を必要とする内容物を収納する容器内に在中させて使用する乾燥剤としては、紙に包装された錠剤タイプの乾燥剤、粉状又は粒状の乾燥剤をフィルムの袋に包装した袋タイプの乾燥剤、乾燥剤層の表裏を紙層やフィルム層で挟着したシートタイプの乾燥剤、また、乾燥剤を混入した合成樹脂を射出成形した乾燥剤樹脂などが使用されていた。   Conventionally, as a desiccant used in a container for storing contents that require a dry environment, a tablet-type desiccant, powdery or granular desiccant packaged in paper is used as a film bag. Packaged bag-type desiccant, sheet-type desiccant in which the front and back of the desiccant layer are sandwiched between paper and film layers, and desiccant resin that is injection-molded with synthetic resin mixed with desiccant are used. It was.

しかしながら、上述した従来の乾燥剤においては、錠剤タイプの乾燥剤は、紙で包装しているため、乾燥能力に瞬発性をもたせることや薄肉化が困難であり、袋タイプの乾燥剤は、袋で包装しているため、乾燥能力に瞬発性をもたせることや薄肉化が困難であり、また、粉状の乾燥剤は凝集し易く、粒状の乾燥剤は表面積が小さいく乾燥能力が低くかった。シートタイプの乾燥剤は、外側に紙層やフィルム層があるため乾燥能力の瞬発性が低く、また、乾燥剤樹脂は、合成樹脂中に乾燥剤が分散しているため乾燥能力の瞬発性が低く、高温成形による乾燥剤からの発生ガスによって、収納する内容物によっては品質が損なわれることもあった。   However, in the conventional desiccant described above, since the tablet-type desiccant is packaged with paper, it is difficult to make the drying ability flash or thin, and the bag-type desiccant It is difficult to make the drying capacity instantaneous and thin, and the powdery desiccant tends to agglomerate, and the granular desiccant has a small surface area and low drying capacity. . Sheet type desiccant has a paper layer and a film layer on the outside, so the drying ability is low, and the desiccant resin has a drying ability because the desiccant is dispersed in the synthetic resin. The quality is low depending on the contents to be stored due to the generated gas from the desiccant due to the high temperature molding.

本発明は、上述の従来の乾燥剤の問題点を解決したものであり、乾燥能力が高く瞬発性があり、薄肉化が可能で、低帯電性及び防塵性があり、内容物に影響するガスの発生がない高機能乾燥剤シートを提供するものである。   The present invention solves the problems of the above-mentioned conventional desiccants, has a high drying capacity, has a flashing property, can be thinned, has a low chargeability and a dustproof property, and affects the contents. The present invention provides a highly functional desiccant sheet that is free from the occurrence of water.

すなわち、本発明の第1の発明は、圧縮成形用金型の雌型上に水分バリア性合成樹脂フィルムを披着し、この水分バリア性合成樹脂フィルムの上から粉末状乾燥剤と粉末状合成樹脂の混合成形材料をキャビティ内に充填し、この上に水分バリア性合成樹脂フィルムを披着し、この水分バリア性合成樹脂フィルム上から雄型のコアで圧縮成形し、成形品を離型して、粉末状乾燥剤と粉末状合成樹脂の混合成形体の外側の所定位置で、密着して重ね合わさる二枚の水分バリア性合成樹脂フィルムを切断し、その外周縁部をヒートシールしてシール部を形成して封止し、使用するときに、シール部の内周の内側近接位置を切断して開封することを特徴とする高機能乾燥剤シートである。   That is, according to the first aspect of the present invention, a moisture barrier synthetic resin film is exhibited on a female die of a compression molding die, and a powdery desiccant and a powdery synthesis are formed on the moisture barrier synthetic resin film. Fill the cavity with a resin molding compound material, display a moisture barrier synthetic resin film on top of this, press the moisture barrier synthetic resin film with a male core, and release the molded product. Then, at a predetermined position outside the mixed molded body of the powdery desiccant and the powdered synthetic resin, cut the two moisture barrier synthetic resin films that are in close contact with each other, heat seal the outer peripheral edge and seal The high-functional desiccant sheet is characterized by cutting and opening the inner proximity position of the inner periphery of the seal portion when the portion is formed, sealed, and used.

そして、本発明の第2の発明は、圧縮成形用金型の雌型上に水分バリア性合成樹脂フィルムを披着し、この水分バリア性合成樹脂フィルムの上に水分バリア性合成樹脂フィルムと熱融着しない水分透過性合成樹脂フィルムを披着し、この水分透過性合成樹脂フィルムの上から粉末状乾燥剤と粉末状合成樹脂の混合成形材料をキャビティ内に充填し、この上に水分透過性合成樹脂フィルムを披着し、この水分透過性合成樹脂フィルム上に、水分透過性合成樹脂フィルムと熱融着しない水分バリア性合成樹脂フィルムを披着し、この水分バリア性合成樹脂フィルム上から雄型のコアで圧縮成形し、成形品を離型して、粉末状乾燥剤と粉末状合成樹脂の混合成形体の外側の所定位置で、密着して重ね合わさる二枚の水分バリア性合成樹脂フィルムと二枚の水分透過性合成樹脂フィルムを切断し、その外周縁部をヒートシールしてシール部を形成して封止し、使用するときに、表裏の水分バリア性
合成樹脂フィルムを水分透過性合成樹脂フィルムから剥離して開封すること特徴とする高機能乾燥剤シートである。
According to a second aspect of the present invention, a moisture barrier synthetic resin film is displayed on a female mold of a compression molding mold, and a moisture barrier synthetic resin film and a heat barrier are formed on the moisture barrier synthetic resin film. A moisture-permeable synthetic resin film that is not fused is displayed, and a mixed molding material of powdery desiccant and powdered synthetic resin is filled into the cavity from above the moisture-permeable synthetic resin film, and moisture-permeable A synthetic resin film was exhibited, and a moisture barrier synthetic resin film that was not thermally fused to the moisture permeable synthetic resin film was exhibited on the moisture permeable synthetic resin film. Two moisture-barrier synthetic resin films that are pressed and molded at the core of the mold, released from the molded product, and closely bonded at a predetermined position outside the mixed molded product of the powdery desiccant and powdered synthetic resin When Cut a sheet of moisture permeable synthetic resin film, heat seal the outer periphery to form a seal part, seal the moisture barrier synthetic resin film on the front and back when using the moisture permeable synthetic resin It is a highly functional desiccant sheet that is peeled off from a film and opened.

本発明の高機能乾燥剤シートは、粉末状乾燥剤と粉末状合成樹脂の混合成形材料を圧縮成形により、粉体状乾燥剤を粉末状合成樹脂をバインダーとしてシート状に固めたものであり、薄肉化が可能であり、多孔質で粉体状乾燥剤の露出面積が多く、凝集もないため、乾燥能力が高く、瞬発性がある。   The high-functional desiccant sheet of the present invention is obtained by compression-molding a mixed molding material of a powdery desiccant and a powdered synthetic resin, and solidifying the powdery desiccant into a sheet using the powdered synthetic resin as a binder, It can be thinned, is porous, has a large exposed area of the powdery desiccant, and does not agglomerate. Therefore, it has a high drying capacity and is instantaneous.

また、本発明の高機能乾燥剤シートは、圧縮の摩擦熱により粉末状合成樹脂が粉末状乾燥剤を包み込むように多孔状態に固着するもであり、粉塵が発生しにくく、電子が移動しにくいため低帯電性であり、高温で成形しないため内容物に影響するガスを発生することがない。また、粉末状乾燥剤と粉末状合成樹脂の混合成形体の表裏に水分透過性合成樹脂フィルムを設けた本発明の高機能乾燥剤シートは、使用しているときの防塵性がさらに良好である。   In addition, the highly functional desiccant sheet of the present invention is fixed in a porous state so that the powdery synthetic resin wraps the powdery desiccant by the frictional heat of compression, so that dust is hardly generated and electrons are not easily transferred. Therefore, it has low chargeability and does not form at a high temperature, and therefore does not generate gas that affects the contents. In addition, the high-functional desiccant sheet of the present invention in which a moisture-permeable synthetic resin film is provided on the front and back of a mixed molded body of a powdery desiccant and a powdery synthetic resin has even better dust resistance when in use. .

また、未開封の本発明の高機能乾燥剤シートは、表裏から水分バリア性合成樹脂フィルムで密封されているため、流通・保管過程における乾燥能力の保持性が極めて良好である。   Moreover, since the unopened highly functional desiccant sheet of the present invention is sealed from the front and back with a moisture-barrier synthetic resin film, the retention of drying capacity in the distribution and storage process is extremely good.
