WATERPROOF SHEET AND WATERPROOFING METHOD INCLUDING USING SAME

A waterproof sheet which is for application to a site to be waterproofed in order to prevent rainwater infiltration thereinto and retard deteriorations which proceed with time， the waterproof sheet comprising: a base layer that comprises a silicone rubber composition reinforced with reinforcing fibers and that has physical properties including high strength; and a pressure-sensitive silicone adhesive layer that has been formed on one surface of the base layer and that has a low hardness and is highly tacky. The waterproof sheet provided by the present invention less breaks than conventional waterproof sheets because of the reinforcement layer， and can conform to cracks or dislocations occurring in the surfaces to which the waterproof sheet has been applied， due to the pressure-sensitive adhesive layer formed on one surface. Since the waterproof sheet includes silicones as main components and is hence excellent in terms of weatherability， heat resistance， and freeze resistance， this waterproof sheet can retain the function required of waterproof sheets， over a longer period.

本防水卷材用于铺设于待防水部位，以阻挡雨水渗入并延缓随时间推移发生的老化。该防水卷材包含：由增强纤维（reinforcing fibers）增强的硅橡胶组合物（silicone rubber composition）构成的基层，该基层具备高强度等物理性能；以及形成于该基层一侧表面的压敏硅酮胶层（pressure-sensitive silicone adhesive layer），该胶层硬度较低且粘性优异。本发明提供的防水卷材因设有增强层，相较传统防水卷材更不易发生断裂；且由于其一侧表面设有压敏胶层，可适配铺贴表面出现的裂缝或错位。由于该防水卷材以硅酮类物质为主要成分，因此具备优异的耐候性、耐热性及抗冻性，可长期维持防水卷材所需的各项功能。
