THERMALLY EXPANSIVE FIREPROOF SHEET
To provide a heat expansible fireproof sheet which can secure heat insulation properties despite a smaller amount of use of foaming agent and the like than before.SOLUTION: The heat expansive fireproof sheet comprises a first resin layer 11, a fireproof sheet 13, and a second resin layer 12 in this order. The first resin layer 11 includes an ethylene-vinyl acetate copolymer (A), a nitrogen-containing foaming agent (B), a phosphorus-based fire retardant (C), a carbonizing agent (D), and titanium dioxide (E). The ethylene-vinyl acetate copolymer (A) has a vinyl acetate content of 15 mass% to 35 mass% and a melt flow rate in the range of 10 g/10 min to 40 g/10 min. The second resin layer 12 includes a thermally decomposable inorganic compound (G) and a thermoplastic resin (H).SELECTED DRAWING: Figure 1
【課題】従来よりも発泡剤等の使用量が少ないにもかかわらず、断熱性を確保することができる熱膨張性耐火シートの提供。【解決手段】第１樹脂層１１と耐熱シート１３と第２樹脂層１２とをこの順に備え、第１樹脂層１１は、エチレン酢酸ビニル共重合体（Ａ）と含窒素発泡剤（Ｂ）とリン系難燃剤（Ｃ）と炭化剤（Ｄ）と二酸化チタン（Ｅ）とを含有し、エチレン酢酸ビニル共重合体（Ａ）は、酢酸ビニル含有率が１５質量％以上３５質量％以下の範囲内、かつ、メルトマスフローレイトが１０ｇ／１０ｍｉｎ以上４０ｇ／１０ｍｉｎ以下の範囲内であり、第２樹脂層１２は、熱分解性無機化合物（Ｇ）と熱可塑性樹脂（Ｈ）とを含有する熱膨張性耐火シート。【選択図】図１
