その気泡構造により不陸調整機能、すなわち貼着される
表面（コンクリート、モルタル等）に存在する表面凹凸
を吸収して新たな平滑表面を与える機能を有する。[Prior Art] A heat insulating sheet having a closed cell structure is usually pasted on the roof ring of a building in order to impart heat insulation or waterproof properties to the floor, walls, etc. (for example, see Utility Model Publication No. 52-37449). reference). This foam sheet has the above-mentioned functions, and
Due to its bubble structure, it has an unevenness adjustment function, that is, a function to absorb surface irregularities existing on the surface to be adhered (concrete, mortar, etc.) and create a new smooth surface.
しかし、従来使用されてきた断熱シートは下記に示す欠

接着剤とを貼着する際、断熱シート上に設けられる補強
シートの上からローラー等により加圧すると、断熱シー
ト中の気泡がしばしば破壊される。1) When attaching the primer under the insulation sheet and the adhesive on the concrete, if pressure is applied with a roller, etc. from above the reinforcing sheet provided on the insulation sheet, air bubbles in the insulation sheet are often destroyed. .
２）床面に断熱シートを貼着したのち防水膜を塗設し、
完全に乾燥しない状態でその上を歩行すると、塗膜が靴
に粘着して靴を持ち上げる際に断熱シート中の気泡の破
壊がしばしば生じる。2) After pasting a heat insulating sheet on the floor, a waterproof membrane is applied.
If you walk on the insulation sheet before it is completely dry, the paint film will stick to the shoe and when you lift the shoe, the air bubbles in the insulation sheet will often burst.
気泡が破壊すると中の空気の温度上昇に伴い膨張し、断
熱シート表面に凹凸が生じ、外観を悪くするだけでなく
、その上に施した塗膜に亀裂を生じるなどして塗膜の劣
化が早くなる。When the bubbles are destroyed, the air inside expands as the temperature rises, creating unevenness on the surface of the insulation sheet, which not only worsens the appearance, but also causes cracks in the paint film applied on top of it, causing deterioration of the paint film. It gets faster.
