VENTILATION BUFFER SHEET WITH ADHESIVE LAYER
To provide a ventilation buffer sheet with an adhesive layer which prevents a step between a partially coated adhesive part and a non-adhesive part from manifesting even on not only the surface of the ventilation buffer sheet with the adhesive layer but also the surface of a coating film waterproof layer, after being laid on a construction surface, and can maintain a smooth surface state.SOLUTION: A ventilation buffer sheet TS with an adhesive layer has a sheet-like object 1 and an adhesive layer 2, wherein the sheet-like object has tensile elastic modulus of 3,000-5,500 MPa on at least the uppermost layer and the lowermost layer, and biaxially stretched polyester films 1a and 1e having a coefficient of linear expansion of 2.0×10-5 or less in a vertical direction and a transverse direction, and a core material 1c which has tensile elastic modulus of 5-2,000 MPa and contains a soft vinyl chloride resin, an ethylene-vinyl acetate copolymer resin, a polyethylene resin, a polypropylene resin, a polyester resin, a natural rubber, a chloroprene rubber, a nitrile rubber, an ethylene propylene rubber, a butyl rubber or a polyurethane rubber as an intermediate layer, are laminated.SELECTED DRAWING: Figure 1
【課題】施工面に敷設された後、部分的に塗工されている粘着剤部位と非粘着剤部位との段差が、粘着層付き通気緩衝シートの表面でも塗膜防水層の表面でも顕在化せず、平滑な表面状態を維持できる粘着層付き通気緩衝シートを提供する。【解決手段】シート状物１及び粘着層２を有する粘着層付き通気緩衝シートＴＳであって、該シート状物が、少なくとも、最上層と最下層に、引張弾性率が３０００～５５００ＭＰａであり、線膨張率が縦方法・横方向ともに２．０×１０－５以下の二軸延伸法ポリエステルフィルム１ａ・１ｅと、中間層に、引張弾性率が５～２０００ＭＰａの、軟質塩化ビニル樹脂、エチレン・酢酸ビニル共重合樹脂、ポリエチレン樹脂、ポリプロピレン樹脂、ポリエステル樹脂、天然ゴム、クロロプレンゴム、ニトリルゴム、エチレンプロピレンゴム、ブチルゴム、又は、ポリウレタンゴムを含有する芯材１ｃと、が積層されている粘着層付き通気緩衝シート。【選択図】図１
