Abstract

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.

Description

technical field [0001] The invention relates to a fireproof board, in particular to a high-strength water-resistant magnesium oxysulfide fireproof board and a preparation method thereof. Background technique [0002] Magnesium cement is a special kind of cement, which was invented by the Frenchman Sorrell in 1867, so it is also called Sorrell cement. And because most of it is formed by the condensation of magnesium chloride and magnesium oxide, it is also called magnesium oxychloride cement. At the same time, it uses magnesium oxide as the main component, and people are used to calling them magnesium cement. For more than 100 years, although scientists have conducted continuous research and development on magnesium cement and made great progress, its fatal shortcomings have seriously hindered people's development and use of it. The inherent disadvantages of magnesium oxychloride cement are: (1) poor water resistance: no matter it is the dissolution theory or the hydrolysis...
