FIRE-RESISTANT MATERIAL
To provide a fire-resistant material which can maintain fire-resistant performance.SOLUTION: A fire-resistant material includes: a first layer containing a first synthetic resin, ammonium polyphosphate and polyhydric alcohol; and a second layer which is arranged so as to overlap the first layer, and contains a second synthetic resin and thermal expansive graphite. Thus, the fire-resistant performance can be maintained for a long period of time from an initial period of fire in a wide temperature range by combining the two layers having different properties.SELECTED DRAWING: Figure 1
【課題】耐火性能を維持することができる耐火材を提供することを目的とする。【解決手段】耐火材は、第１の合成樹脂と、ポリリン酸アンモニウムと、多価アルコールとを含有する第１の層と、前記第１の層に重ねて配置され、第２の合成樹脂と、熱膨張性黒鉛とを含有する第２の層とを備える。このように、性質の異なる２つの層を組み合わせることによって、火災の初期から長時間かつ広い温度範囲にわたって、耐火性能を維持することができる。【選択図】図１
