NONFLAMMABLE SHEET, SMOKEPROOF VERTICAL WALL AND SMOKEPROOF SCREEN/CURTAIN USING NONFLAMMABLE SHEET, AND METHOD FOR PRODUCING NONFLAMMABLE SHEET
To provide a nonflammable sheet which can be easily produced, prevents generation of a waste generated in a conventional production process, and is excellent in flexibility and cutting properties.SOLUTION: A nonflammable sheet 1 that is formed by laminating a thermoplastic resin layer 4 on both surfaces of a glass cloth 2 through an adhesive layer 3, where a yarn count of a glass fiber in the glass cloth 2 is 3-20 tex, a density total of warp and weft is 80-190/25 mm, the adhesive layer 3 is formed of a resin composition containing a polyvinyl chloride (PVC) paste resin and at least one plasticizer having a molecular weight of 380 or less, a percentage content of the plasticizer to the total amount of the resin composition constituting the adhesive layer 3 is 30-80 mass%, and total light transmittance thereof is 75% or more.SELECTED DRAWING: Figure 1
【課題】容易に製造でき、従来の製造過程で発生していた廃棄物が発生せず、柔軟性及び裁断性に優れた不燃性シートの提供。【解決手段】ガラスクロス２の両面に接着層３を介して熱可塑性樹脂層４を積層してなる不燃性シート１において、ガラスクロス２中のガラス繊維の番手が３〜２０ｔｅｘ、経糸と緯糸の密度合計が８０〜１９０本／２５ｍｍであり、接着層３が、ポリ塩化ビニル（ＰＶＣ）ペーストレジンと、少なくとも１種の分子量３８０以下の可塑剤とを含む樹脂組成物からなり、接着層３を構成する樹脂組成物の総量に対する前記可塑剤の含有率が３０〜８０質量％であり、かつ、全光線透過率が７５％以上である不燃性シート１。【選択図】図１
