Fireproof gypsum board and manufacturing method thereof
The invention provides a fireproof gypsum board and a manufacturing method thereof, and relates to the field of gypsum boards. The fireproof gypsum board comprises a flame-retardant gypsum layer, a first heat conduction layer and a second heat conduction layer, the first heat conduction layer is arranged on one side of the flame-retardant gypsum layer, and the second heat conduction layer is arranged on the other side of the flame-retardant gypsum layer; the flame-retardant gypsum layer comprises a gypsum component and a basic cupric carbonate component, the interior of the flame-retardant gypsum layer is foamed to form closed air holes, and the closed air holes are filled with flame-retardant gas in a sealed mode. When the flame-retardant gypsum layer is heated and decomposed, the blocky gypsum becomes powder, the flame-retardant gas in the closed air holes is released accordingly, and the carbon dioxide gas released by the reaction of the basic cupric carbonate and the flame-retardant gas released by the decomposition of the flame-retardant gypsum layer jointly form a flame-retardant atmosphere. The fireproof gypsum board is low in production process difficulty, the structural strength of the gypsum board at the normal temperature is guaranteed, the amount of gas released by the gypsum board at the high temperature is large, and the effects of effectively inhibiting combustion and preventing fire are achieved.
本发明提供了一种防火型石膏板及其制作方法，涉及石膏板领域。防火型石膏板包括阻燃石膏层、第一导热层和第二导热层，第一导热层设置于阻燃石膏层的一侧，第二导热层设置于阻燃石膏层的另一侧；阻燃石膏层包括石膏成分和碱式碳酸铜成分，阻燃石膏层的内部发泡形成有封闭气孔，封闭气孔的内部密封填充有阻燃气体。当阻燃石膏层发生受热分解时，块状石膏变为粉末状，封闭气孔中的阻燃气体随之释放出来，碱式碳酸铜反应释放出的二氧化碳气体与阻燃石膏层分解释放出的阻燃气体共同组成了阻燃气氛。该防火型石膏板的生产工艺难度低，保证了石膏板在常温时的结构强度，且高温情况下石膏板释放出的气体量大，起到了有效抑制燃烧和防火的作用。
