High-strength waterproof magnesium oxysulfate fireproof board and manufacturing method thereof
The invention discloses a high-strength waterproof magnesium oxysulfate fireproof board. The high-strength waterproof magnesium oxysulfate fireproof board comprises a fiber layer and slurry, wherein the slurry comprises a bottom material, an intermediate material and a surface material; the bottom material, the intermediate material and the surface material respectively comprise the following components in parts by weight: 80-240 parts of magnesium sulfate solution having the baume degree being 23-28 degrees, 100-300 parts of 85% light calcined magnesia, 0.1-5 parts of tartrate, 2-10 parts of butylbenzene emulsion, 0-100 parts of heavy-weight filler, 0-100 parts of lightweight filler and 0.1-5 parts of water reducing agent. The high-strength waterproof magnesium oxysulfate fireproof board has the advantages of low thermal expansion and shrinkage rate, low heat conduction coefficient, high strength, excellent waterproof property, no warping and deformation, over 0.95 softening coefficient, no halogenation, no scumming, excellent freezing resistance and noninflammability and the like.
