FIRE-RESISTANT INSULATING SHEET, MANUFACTURING METHOD OF FIRE-RESISTANT INSULATING SHEET, AND FLAME RETARDANT REFRACTORY MATERIAL
To provide fire-resistant insulating sheet with surface strength as allowing its high fire resistance and high workability to be unchanged and further provide flame retardant refractory material using the fire-resistant insulating sheet.SOLUTION: Fire-resistant insulating sheet including: fiber sheet containing thermally expansive graphite and aluminum hydroxide; sodium silicate; and phosphorus or phosphorus compound, is from 35 to 85% in coefficient of water absorption of the fire-resistant insulating sheet. The coefficient of the water absorption exhibits a water absorption amount in the fire-resistant insulating sheet which has been soaked in water at room temperature for two minutes after placed under environment of room temperature and humidity for one hour, being represented by formula (1) where a weight before water absorption is a, and a weight after water absorption b. (Formula 1) Water absorption (%)=(b-a)/bx100.SELECTED DRAWING: Figure 1
【課題】高い耐火性と施工時の高い作業性を維持しながら、表面強度の高い耐火断熱シートを提供することであり、さらに前記耐火断熱シートを適用した防炎耐熱材を提供する。【解決手段】熱膨張性黒鉛と水酸化アルミとを担持する繊維シートと、ケイ酸ナトリウムと、リン又はリン化合物とを含む耐火断熱シートであって、前記耐火断熱シートの吸水率が３５〜８５％である、耐火断熱シート。前記吸水率は前記耐火断熱シートを、常温常湿の環境下に１時間静置したのち、常温の水に２分間浸漬した後の吸水量を表わし、吸水前の重量をａ、吸水後の重量をｂとした場合に下式１で表される。（式１）吸水率（％）＝（ｂ−ａ）／ｂ×１００【選択図】図１
