Fire-proof gypsum board
The invention relates to a fire-proof gypsum board which comprises components as follows: 20 parts of semi-hydrated gypsum powder, 5 parts of fly ash, 1 part of glass fibers, 2 parts of volcanic rock fibers, 5 parts of high-strength gypsum, 1 part of sodium sulfate, 15 parts of zirconium silicate, 2 parts of calcium carbonate, 4 parts of aluminum oxide clay, 7 parts of magnesium oxide, 6 parts of magnesium chloride and 1 part of epoxy resin. The fireproof function of the fire-resistant gypsum board can reach the national requirement standard, the connection strength of the whole gypsum board is greatly improved, the fire-proof performance of connection positions between boards is also improved, and the cost of the whole gypsum board is reduced.
