MOISTUREPROOF SHEET FOR HOUSING MATERIAL AND DECORATIVE PLATE
PROBLEM TO BE SOLVED: To provide a moistureproof sheet for housing material which suppresses warpage of a decorative plate against an influence by a temperature of an environment and a change of humidity even when applied to a fitting such as a door panel, and can keep adhesiveness to a base material.SOLUTION: There is provided a moistureproof sheet 1 for housing material which has a base material layer 2 made from a biaxially stretched synthetic resin, a vapor-deposited layer 3 that is provided on one surface side of the base material layer 2 and is made from an inorganic oxide, a resin layer 4 that is provided on the vapor-deposited layer 3 and mainly contains polyvinyl alcohol, a primer layer 5 for adhesion provided on the surface of the resin layer 4, and a surface wettability modification portion 6 that is formed on the other surface of the base material layer 2 and has modified surface wettability. Preferably, a water vapor permeation of the whole sheet 1 is 1.0 g/mday or less, and the moisture proof sheet has such transparency that the sheet back 6 side can be visually recognized from the sheet surface 5 side.SELECTED DRAWING: Figure 1
【課題】ドアパネルなどの建具に適用しても、環境の温度や湿度の変化による影響に対し、化粧板の反りを抑制し且つ基材との接着性を維持できる建材用防湿シートを提供する。【解決手段】２軸延伸の合成樹脂製からなる基材層２と、基材層２の一方の面側に設けられた無機酸化物からなる蒸着層３と、蒸着層３の上に設けられ主成分をポリビニルアルコールとした樹脂層４と、樹脂層４の表面に設けられた接着用プライマー層５と、基材層２の他方の面に形成され表面濡れ性が改質されている表面濡れ性改質部６と、を有する建材用防湿シート１。好ましくは、シート１全体の水蒸気透過度が１．０ｇ／ｍ２・日以下であり、シート表面５側から裏面側６へ視認可能な透明度を有することが更に好ましい建材用防湿シート１。【選択図】図１
