LAMINATED SHEET
PROBLEM TO BE SOLVED: To provide a laminated sheet having high waterproofness while being lightweight.SOLUTION: A laminated sheet is obtained by laminating an intermediate layer containing a resin on at least one surface of a waterproof layer containing asphalt, and further laminating a fiber layer being a fiber structure on the intermediate layer. The fiber structure may be a hydrophobic non-woven fabric (in particular, polypropylene-based long fiber non-woven fabric) having a plurality of embossed recessed parts at a waterproof layer side. The intermediate layer may contain a polyolefin-based resin. An average thickness of the waterproof layer may be 0.5 mm or less. The waterproof layer may be a structure containing no fiber structure. A unit area mass of the laminated sheet may be 0.9 kg/mor less. In the laminated sheet, an intermediate layer and a fiber layer may be laminated on both surfaces of the waterproof layer. The laminated sheet may be a roof underlayment material.SELECTED DRAWING: None
【課題】軽量であっても、防水性が高い積層シートを提供する。【解決手段】アスファルトを含む防水層の少なくとも一方の面に樹脂を含む中間層を積層し、この中間層の上に繊維構造体である繊維層をさらに積層して積層シートを得る。前記繊維構造体は防水層側に複数のエンボス凹部を有する疎水性不織布（特にポリプロピレン系長繊維不織布）であってもよい。前記中間層はポリオレフィン系樹脂を含んでいてもよい。前記防水層の平均厚みは０．５ｍｍ以下であってもよい。前記防水層は繊維構造体を含まない構造体であってもよい。前記積層シートの単位面積質量は０．９ｋｇ／ｍ２以下であってもよい。前記積層シートは、防水層の両面にそれぞれ中間層及び繊維層が積層されていてもよい。前記積層シートは、屋根下葺材であってもよい。【選択図】なし
