NON-INFLAMMABLE WALL SURFACE SHEET
To provide a non-inflammable wall surface sheet that has a small total calorific value and is less prone to damage.SOLUTION: A non-inflammable wall surface sheet includes a sheet body layer 2 and a design layer 3 laminated on a surface of the sheet body layer 2. The sheet body layer 2 includes a resin component containing chlorinated vinyl chloride, an inorganic filler, and a plasticizer. The non-inflammable wall surface sheet includes 40-80 wt.% of the inorganic filler relative to 100 wt.% of the whole sheet body layer. In a pyrogenicity test where radiation heat of 50 kW/m2 is emitted from a radiant electric heater to a sheet surface, a total calorific value for 20 minutes after starting heating is less than 7.2 MJ/m2, and an overall thickness is 0.30-0.65 mm.SELECTED DRAWING: Figure 2
【課題】 総発熱量が小さく、且つ損傷し難い不燃壁面シートを提供する。【解決手段】 シート本体層２と、前記シート本体層２の表面に積層された意匠層３と、を有し、前記シート本体層２が、塩素化塩化ビニルを含む樹脂成分と、無機充填剤と、可塑剤と、を含み、前記無機充填剤が、前記シート本体層全体を１００重量％としたときに、４０重量％～８０重量％含まれており、輻射電気ヒーターからシート表面に５０ｋＷ／ｍ２の輻射熱を照射する発熱性試験における加熱開始後の２０分間の総発熱量が７．２ＭＪ／ｍ２未満であり、全厚が０．３０ｍｍ～０．６５ｍｍである。【選択図】 図２
