THERMOEXPANDABLE FIREPROOF SHEET
To provide a thermoexpandable fireproof sheet which can, in the case of no fire, prevent moisture absorption thereby inhibiting deterioration of fire resistance performance, and can, in the case of fire, prevent inhibition of formation of a foam heat insulating layer thereby exhibiting the fire resistance performance.SOLUTION: A thermoexpandable fireproof sheet 1 comprises a heat-resistant sheet 13, a first resin layer 11 and a second resin layer 12 in this order. The first resin layer 11 contains a blowing agent. The second resin layer 12 has a melting temperature in a range from 150°C to 400°C inclusive.SELECTED DRAWING: Figure 1
【課題】非火災時には、吸湿しにくくして、耐火性能が劣化するのを抑制することができ、火災時には、発泡断熱層の形成を阻害しにくくして、耐火性能を発揮させることができる熱膨張性耐火シートの提供。【解決手段】耐熱シート１３と第１樹脂層１１と第２樹脂層１２とをこの順に備え、第１樹脂層１１は、発泡剤を含有し、第２樹脂層１２は、溶融温度が１５０℃以上４００℃以下の範囲内である熱膨張性耐火シート１。【選択図】図１
