UNDERLAYER MATERIAL FOR WATERPROOFING URETHANE COATING
To provide an underlayer material for waterproofing urethane coating which has good adhesiveness with a urethane coated waterproof material, which has excellent strength and rich durability, which can be cut easily by a pair of scissors and a cutter knife, and which can retain smoothness without bending even in a portion where a self-adhesive layer is not laminated.SOLUTION: An underlayer material for waterproofing urethane coating is made of a sheet-like molded article 2 formed by calcium carbonate (CaCO3) 60-80% and high density polyethylene (HDPE resin) or polypropylene resin (PP resin) 40%-20%, and polyurethane resin 3 dissolved in an organic solvent is coated on the surface.SELECTED DRAWING: Figure 1
【課題】ウレタン塗膜防水材との付着性がよく、しかも、強度に優れ、耐久性に富み、また、鋏やカッターナイフ等での切断も容易で、しかも、自己粘着層が積層されていない部分でも撓まずに平滑性が保持できるウレタン塗膜防水用下張り材を提供する。【解決手段】炭酸カルシウム（ＣａＣＯ３）６０〜８０％と高密度ポリエチレン（ＨＤＰＥ樹脂）もしくは、ポリプロピレン樹脂（ＰＰ樹脂）４０％〜２０％で形成したシート状成形品２からなり、表面に有機溶剤に溶解したポリウレタン樹脂３を塗布した。【選択図】図１
