FIREPROOF MULTILAYER SHEET
To provide a fireproof multilayer sheet having at least a substrate, a thermal expansion material, and a separator, in which detachment of the substrate and the separator respectively, and generation of wrinkles in the substrate and the separator respectively are prevented even with flexure.SOLUTION: A fireproof multilayer sheet has a substrate 1, a thermal expansion material 2, an adhesive layer 3 and a separator 4 which are arranged on one surface of the substrate 1. The thermal expansion material 2 consists of a thermal expandable resin composition containing a binder resin and thermal expandable graphite. The adhesive layer 3 and the separator 4 are arranged on a surface in an opposite side to a surface where the substrate 1 of the thermal expansion material 2 is arranged. Thickness of the substrate 1 is 1 to 20% of the fireproof multilayer sheet 2, and thickness of the separator 4 is 0.3 to 10% of the fireproof multilayer sheet 2.SELECTED DRAWING: Figure 1
【課題】湾曲しても、基材、セパレーターのそれぞれの剥離と、基材、セパレーターのそれぞれへの皺の発生が防止される、少なくとも基材と熱膨張材とセパレーターが設けられている耐火多層シートを提供する。【解決手段】耐火多層シートが、基材１と基材１の一方の面に設けられる熱膨張材２と粘着層３とセパレーター４とを備える。熱膨張材２は、バインダー樹脂及び熱膨張性黒鉛を含む熱膨張性樹脂組成物からなる。粘着層３とセパレーター４は、熱膨張材２の基材１が設けられた面と反対側の面に設けられる。基材１の厚みは耐火多層シート２の１〜２０％であり、セパレーター４の厚みは耐火多層シート２の０．３〜１０％である。【選択図】図１
