The invention discloses a flame-retardant ceiling and a preparation method thereof. The flame-retardant ceiling is prepared from the following raw materials: modified phosphogypsum, desulfurized gypsum, aluminum silicate, modified aluminum hydroxide, barium stearate, fly ash, talcum powder, sodium tripolyphosphate, calcium borate, sodium polyacrylate and deionized water. The flame-retardant ceiling disclosed by the invention has good flame-retardant performance and compressive strength; according to the flame-retardant ceiling, phosphogypsum is modified, modified phosphogypsum with excellent performance is obtained, the modified phosphogypsum is compact in structure, a large amount of soluble phosphorus, soluble fluorine and organic matter impurities in the phosphogypsum are removed in themodification process, and the intermolecular acting force of the phosphogypsum is improved. Therefore, the modified phosphogypsum capable of remarkably improving flame retardance and compressive strength is obtained, massive accumulation of phosphogypsum can be relieved by using phosphogypsum, and environmental pollution caused by phosphogypsum is reduced.
本发明公开了一种阻燃天花板及其制备方法，由以下原料制成：改性磷石膏、脱硫石膏、硅酸铝、改性氢氧化铝、硬脂酸钡、粉煤灰、滑石粉、三聚磷酸钠、硼酸钙、聚丙烯酸钠、去离子水。本发明所述的阻燃天花板具有良好的阻燃性能和抗压强度；本发明所述的阻燃天花板通过使用对磷石膏进行改性，得到了性能优异的改性磷石膏，改性后的磷石膏结构致密，磷石膏中的大量可溶磷、可溶氟以及有机物杂质在改性过程中被去除，提高了磷石膏分子间的作用力，从而得到了能够显著提高阻燃性能和抗压强度的改性磷石膏，通过使用磷石膏能够缓解磷石膏的大量堆积，并且减少磷石膏对环境的污染。
