UNDERLAYER CUSHIONING SHEET, AND WATERPROOF STRUCTURE
PROBLEM TO BE SOLVED: To provide an underlayer cushioning sheet that accelerates curing of a coat and curtails work period, without affecting ease of coating work, when implementing waterproofing work using a single-component (moisture-curing) waterproof material.SOLUTION: An underlayer cushioning sheet is provided that is installed on a surface of a substrate 20, and a waterproof coat is formed on the underlayer cushioning sheet. The underlayer cushioning sheet includes a cushioning layer 12 having an overlapped surface 12a, and a curing promotion layer 11 having a coat formation surface 11a on a side opposite the overlapped surface 12a. The coat formation surface 11a of the curing promotion layer 11 has a waterproof coat of a polyurethane resin, formed by applying a single-component liquid waterproof material. The curing promotion layer 11 contains a reactive material that reacts with the liquid waterproof material, and either [1] or [2] below applies to the reactive material: [1] containing a functional group that reacts with isocyanate contained in the liquid waterproof material; or [2] forming a functional group that reacts with a component of the liquid waterproof material, by reacting with a latent curing agent contained in the liquid waterproof material.SELECTED DRAWING: Figure 1
【課題】１液型（湿気硬化型）の防水材を用いた防水施工において、塗膜の硬化速度を高めて工期の短縮を図ることができ、かつ塗布作業の容易さが損なわれることがない下張緩衝シートを提供する。【解決手段】下地２０の表面に設置されて、その上に防水塗膜が形成される下張緩衝シートを提供する。重ね面１２ａを有する緩衝層１２と、重ね面１２ａとは反対側に塗膜形成面１１ａを有する硬化促進層１１とを備えている。硬化促進層１１の塗膜形成面１１ａは、１液型の液状防水材の塗布によりポリウレタン樹脂からなる防水塗膜が形成される。硬化促進層１１は、液状防水材と反応可能な反応性材料を含み、前記反応性材料は、次の［１］、［２］のいずれかに該当する。［１］前記液状防水材に含まれるイソシアネートと反応可能な官能基を有する。［２］前記液状防水材に含まれる潜在性硬化剤と反応して、前記液状防水材の成分と反応可能な官能基を生成する。【選択図】図１
