MOISTURE-PROOF FILM
To provide a moisture-proof film used for a decorative material for a floor where curving or warping is restrained from being occurred even when a decorative sheet with low moisture permeability is laminated on a front surface of woody base material.SOLUTION: The present invention relates to a moisture-proof film used in a decorative material for a floor that is in a laminated structure having, from a front surface to a rear surface, a decorative sheet 1 with at least one thermoplastic resin layer, a woody base material 3 of which dimensional change amount per 1% water content rate is greater than 0.02% and of which average water content rate is 6-10 wt.%, and the moisture-proof film 5. The moisture-proof film has a water-vapor permeability equal to or smaller than 1 g/m2 24 hr and is a laminate body having a primer layer consisting of at least one selected from a group consisting of an ester-based resin, an urethane resin, an acrylic resin, a polycarbonate-based resin, a polyvinyl chloride-acetic-acid copolymer, a polyvinyl butyral-based resin and a nitro cellulose-based resin, and an aluminum vapor deposition layer in this order on one surface of the thermoplastic resin layer.SELECTED DRAWING: Figure 1
【課題】木質基材のおもて面に透湿性の低い化粧シートを積層した場合でも、反りや曳き曲がりの発生が抑制された床用化粧材に用いる防湿フィルムを提供する。【解決手段】おもて面から裏面にかけて、少なくとも一層の熱可塑性樹脂層を備える化粧シート１と、１％含水率変化当たりの寸法変化量が０．０２％よりも大きく、且つ平均含水率が６〜１０重量％である木質基材３と、防湿フィルム５とを具備する積層構成を備える床用化粧材に用いる前記防湿フィルムであって、前記防湿フィルムは、透湿度が１ｇ／ｍ２・２４時間以下であり、熱可塑性樹脂フィルムの片面にエステル系樹脂、ウレタン系樹脂、アクリル系樹脂、ポリカーボネート系樹脂、塩化ビニル−酢酸ビニル共重合体、ポリビニルブチラール系樹脂、及びニトロセルロース系樹脂からなる群から選択される少なくとも一種からなるプライマー層とアルミニウム蒸着層とを順に備えている積層体である。【選択図】図１
