FIRE-RESISTANT MATERIAL AND COMPOSITE FIRE-RESISTANT SHEET
To provide a fire-resistant material serving as a char layer which is easily expanded by being heated and which is less likely to be deformed at high temperature.SOLUTION: A fire-resistant material includes a carbonizing agent and a foaming agent. A temperature at which the value of a shear storage elastic modulus becomes 1×105 Pa in a temperature range at 345°C or lower in a relation curve between a shear storage elastic modulus and temperature while putting the shear storage elastic modulus at a measurement frequency 1 Hz of the fire-resistant material on a vertical axis and putting the temperature on a lateral axis, includes a first temperature T1 and a second temperature T2 higher than the first temperature T1. In the relation curve, the shear storage elastic modulus decreases according to increase in temperature at the first temperature T1 and the shear storage elastic modulus increases according to increase in temperature at the second temperature T2. A decomposition temperature or a vaporization temperature of the foaming agent is lower than the second temperature T2.SELECTED DRAWING: Figure 1
【課題】本開示は、加熱されることで膨張しやすく、かつ高温下において変形しにくい炭化層となりうる耐火材料を提供する。【解決手段】耐火材料は、炭化剤と、発泡剤とを含有する。耐火材料の測定周波数１Ｈｚでのせん断貯蔵弾性率を縦軸、温度を横軸とするせん断貯蔵弾性率−温度の関係曲線において、３４５℃以下の温度範囲における、せん断貯蔵弾性率の値が１×１０5Ｐａになる温度は、第一温度Ｔ1と、第一温度Ｔ1よりも高い第二温度Ｔ2とを含む。関係曲線において、第一温度Ｔ1では温度上昇にしたがってせん断貯蔵弾性率が低下し、かつ第二温度Ｔ2では温度上昇にしたがってせん断貯蔵弾性率が増大する。発泡剤の分解温度又は気化温度は、第二温度Ｔ2よりも低い。【選択図】図１
