Problems solved by technology

At present, the current oxidized board is processed by mixing magnesium oxychloride cement and some modifiers. The produced fireproof board is easy to be damp and brine and has poor whiteness, which is easy to cause warping, deformation and cracking of the board, which greatly affects the product. The quality of the product limits the application of the product

Embodiment 1

[0015] Embodiment 1 Magnesia refractory board is formed by mixing the following raw materials, and the parts by weight of each raw material are as follows: 75 parts of light-burned magnesium oxide, 30 parts of magnesium chloride, 6 parts of perlite, 2 parts of bentonite, 15 parts of wood chips, 0.5 part of rosin, 6 parts of talcum powder, 4 parts of wollastonite powder, and 8 parts of solid essence.

Embodiment 2

[0016] Embodiment 2 Magnesia refractory board is formed by mixing the following raw materials, and the parts by weight of each raw material are as follows: 65 parts of light-burned magnesium oxide, 38 parts of magnesium chloride, 8 parts of perlite, 3 parts of bentonite, 12 parts of wood chips, 1 part of rosin, 8 parts of talcum powder, 8 parts of wollastonite powder, and 12 parts of solid essence.

Embodiment 3

[0017] Embodiment 3 Magnesia refractory board is formed by mixing the following raw materials, and the parts by weight of each raw material are as follows: 82 parts of light-burned magnesium oxide, 23 parts of magnesium chloride, 5 parts of perlite, 2 parts of bentonite, 19 parts of wood chips, 0.3 part of rosin, 4 parts of talcum powder, 1 part of wollastonite powder, and 3 parts of solid essence.

[0018] The above raw materials are batched, then forcedly stirred to form a magnesium oxychloride slurry, and then mechanically rolled and formed, naturally cured and consolidated, demoulded to dry, cut and shaped to form a magnesium oxide board.

Abstract

The invention discloses a magnesium oxide refractory plate, which is prepared by mixing the following raw materials by weight: 63-83 parts of light calcined magnesium oxide, 21-40 parts of magnesium chloride, 5-8 parts of perlite, 2-3 parts of bentonite, 8-20 parts of sawdust, 0.1-1 part of rosin, 4-8 parts of talcum powder, and 1-8 parts of wollastonite powder. The magnesium oxide refractory plate provided in the invention has the advantages of good halogen resisting performance, difficult buckling deformation cracking, long service life, and good quality.

Description

[0001] technical field [0002] The invention belongs to the technical field of building materials, in particular to a magnesium oxide refractory board. Background technique [0003] Magnesium oxide board is a new type of multifunctional building material, because it not only has the light weight, flexibility and reprocessing performance of wood-based organic boards, but also has the fire resistance and water resistance of inorganic boards. Magnesia board is widely used in wall, ceiling, floor lining. At present, the current oxidized board is processed by mixing magnesium oxychloride cement and some modifiers. The produced fireproof board is easy to be damp and brine and has poor whiteness, which is easy to cause warping, deformation and cracking of the board, which greatly affects the product. The quality of the product limits the application of the product. Contents of the invention [0004] In order to solve the above problems, the present invention provides a magnesi...
