FIREPROOF SHEET FOR WALLPAPER BACKING
To provide a fireproof sheet for wallpaper backing, which has excellent coatability of an inorganic particle layer, has good flatness of a polyvinyl chloride resin-coated surface of the fireproof sheet for wallpaper backing, does not cause the strike-through of the polyvinyl chloride resin, combines flexibility, fire resistance, and noncombustibility, and has excellent folding resistance.SOLUTION: There is provided a fireproof sheet for wallpaper backing including a base material and an inorganic particle layer. The base material contains glass fibers, wet heat adhesive binder fibers, fibrillated fibers, and an inorganic binder having a fiber shape. The glass fibers contain glass fibers with both circular and flattened cross-sections. The content of the fibrillated fiber is 2 mass% or more and 9 mass% or less with respect to the total raw material constituting the base material. The inorganic particle layer contains inorganic particles and an inorganic binder.SELECTED DRAWING: Figure 1
【課題】本発明の課題は、無機粒子層の塗工性に優れ、壁紙裏打ち用耐火シートにおけるポリ塩化ビニル樹脂塗工表面の平坦性が良好で、さらにポリ塩化ビニル樹脂の裏抜けがなく、柔軟性と耐火性と不燃性を兼ね備え、耐折強度に優れた壁紙裏打ち用耐火シートを提供することにある。【解決手段】基材と無機粒子層とを含有し、該基材がガラス繊維と湿熱接着性バインダー繊維とフィブリル化繊維と繊維形状を有する無機バインダーを含有し、該ガラス繊維が円形断面と扁平断面の両方のガラス繊維を含有し、該フィブリル化繊維の含有率が、該基材を構成する全原料に対して２質量％以上９質量％以下であり、該無機粒子層が無機粒子と無機バインダーを含有していることを特徴とする壁紙裏打ち用耐火シート。【選択図】図１
