Ardealite fireproof gypsum board and preparation method thereof
The invention provides an ardealite fireproof gypsum board and a preparation method thereof. The fireproof gypsum board comprises the following formula components in percentage by weight: 70-90% of ardealite; 5-20% of high bauxite; 1-8% of refractory fiber; 0.5-2% of a water reducing agent; 0.005-0.01% of a retarder; 0-0.5% of a waterproof agent; 0.1-0.2% of a defoaming agent; and 3-10% of a pH regulator. All indexes of the gypsum board provided by the invention are superior to performance requirements in GB/T23451-2009, the fire endurance is long and can be longer than 4 hours, the physical and mechanical properties are high, the water absorption rate is small, the production and processing are convenient and rapid, the problems that a common gypsum board on the market is short in fire endurance and cannot be used in a special high fire endurance environment are effectively solved, another new path is opened up for comprehensive utilization of phosphogypsum, and the prospect is wide.
本发明提出一种磷石膏防火石膏板及其制备方法，该防火石膏板包括以下重量比的配方成分：磷石膏70～90％；高铝矾土5～20％；耐火纤维1～8％；减水剂0.5～2％；缓凝剂0.005～0.01％；防水剂0～0.5％；消泡剂0.1～0.2％；PH调节剂3～10％。本发明提供的石膏板所有指标优于GB/T23451‑2009中性能要求，且耐火极限长，能大于4h，且物理力学性能高，吸水率小，生产加工方便快捷，有效解决了市场上普通石膏板耐火极限短，不能用于特殊高耐火极限环境的问题，为磷石膏综合利用开辟了另一条新路径，前景广阔。
