    • Provided is an underlay cushioning sheet that is arranged on the surface of a foundation and that has a waterproof coating film formed thereon. The underlay cushioning sheet is provided with a cushioning layer having an overlay surface and a curing acceleration layer having a coating film formation surface on the opposite side from the overlay surface. A waterproof coating film comprising a polyurethane resin is formed on the coating film formation surface of the curing acceleration layer by applying a one pack-type liquid waterproofing material. The curing acceleration layer comprises a reactive material that is capable of reacting with the liquid waterproofing material. The reactive material either (1) comprises a functional group that is capable of reacting with an isocyanate included in the liquid waterproofing material or (2) reacts with a latent curing agent included in the liquid waterproofing material and generates a functional group that is capable of reacting with the components of the liquid waterproofing material.
    • 本发明提供一种衬垫缓冲片,其布置在基础的表面上并且具有在其上形成的防水涂膜。 衬垫缓冲片设置有缓冲层,缓冲层具有覆盖表面和固化加速层,固化加速层在覆盖表面的相对侧上具有涂覆膜形成表面。 通过涂布单组分型液体防水材料,在固化促进层的涂膜形成表面上形成包含聚氨酯树脂的防水涂膜。 固化促进层包含能够与液体防水材料反应的反应性材料。 (1)的反应性材料包含能够与包含在液体防水材料中的异氰酸酯反应的官能团,或(2)与包含在液体防水材料中的潜伏性固化剂反应并产生官能团,所述官能团能够 与液体防水材料的组分反应。
