Description
【発明の詳細な説明】 〔産業上の利用分野〕 本発明は、PVA系ラミネートフィルムに関する。更に
詳しくは、ガスバリヤー性および可動性を備えたPVA系
ラミネートフィルムに関する。The present invention relates to a PVA-based laminate film. More specifically, the present invention relates to a PVA-based laminated film having gas barrier properties and movability.

れていたが、これらのゴム材料は樹脂材料と比較して、
可動性（耐歪特性）や圧縮永久歪の点ではすぐれている
ものの、肝心のガスバリヤー性の点では十分に満足され
ていない。Gas barrier properties such as butyl rubber and nitrile rubber have been used in places where gas barrier properties and mobility are required, such as bladders, diaphragms, hoses, and bellows. do it,
Although excellent in terms of mobility (distortion resistance) and compression set, they are not sufficiently satisfied in terms of essential gas barrier properties.
また、ゴム材料と樹脂材料とを積層すると、圧縮永久

塑剤を加えることにより改善可能であるが、ポリビニル
アルコール系樹脂に使用可能なポリオール系可塑剤は、
加熱条件下で蒸発し易く、長時間の使用に耐えられない
という問題がみられる。Further, when a rubber material and a resin material are laminated, although the compression set becomes good, there is a drawback that the resin is low in critical strain (elongation), so that cracks tend to occur particularly in a low temperature range. The problem of cracking in such a low-temperature region can be improved by adding a plasticizer to the resin material, but a polyol-based plasticizer that can be used for the polyvinyl alcohol-based resin is:
There is a problem that the composition easily evaporates under heating conditions and cannot be used for a long time.

る。In commercially available polyvinyl alcohol-based resin films,
Usually, about 5% of glycerin is added, but the present invention suppresses the evaporation of the plasticizer due to the heating experience of the polyvinyl alcohol-based resin film to which the polyol-based plasticizer is added, and improves the low-temperature characteristics of the plasticizer. The purpose is.
