TRANSPARENT NONFLAMMABLE SHEET
PROBLEM TO BE SOLVED: To provide a transparent nonflammable sheet having high transparency and high mechanical strength and a suppressed warpage by heat, which can be used for a smokeproof hanging wall, a smokeproof shutter, a partition wall, a smokeproof curtain, a touch panel or the like.SOLUTION: There is provided a transparent nonflammable sheet 1 which comprises a plurality of glass fiber cloths 2 and a cured resin composition layer 3 impregnated in the plurality of glass fiber cloths 2, where the cured resin composition layer 3 is formed of a cured product of a resin composition containing a curable resin, the central part in the thickness direction of the glass fiber cloths 2 is positioned on the surface side from the central part in the thickness direction of the cured resin composition layer 3, each of the glass fiber cloths 2 is disposed on both surface sides of the cured resin composition layer 3, and the transparent nonflammable sheet 1 has a total light transmittance of 80% or more and a haze of 30% or less.
【課題】高い透明性及び高い機械的強度を有し、更に熱による反りが抑制された透明不燃性シートの提供。【解決手段】複数のガラス繊維布帛２と、複数のガラス繊維布帛２に含浸された硬化樹脂組成物層３とを含む透明不燃性シート１であって、硬化樹脂組成物層３が、硬化性樹脂を含む樹脂組成物の硬化物により形成されており、ガラス繊維布帛２の厚み方向における中央部が、硬化樹脂組成物層３の厚み方向における中央部よりも表面側に位置し、硬化樹脂組成物層３の少なくとも両表面側において、各々ガラス繊維布帛２が配置され、透明不燃性シート１の全光線透過率が８０％以上であり、透明不燃性シート１のヘーズが３０％以下である、透明不燃性シート１。【効果】透明不燃性シートは、透明性が高く、機械的強度も高く、熱による反りも効果的に抑制されており、防煙垂壁、防煙シャッター、間仕切壁、防煙カーテン、タッチパネル等に使用できる。【選択図】図２
