Problems solved by technology

However, the existing magnesia boards are often eaten by moths after being used for a long time, which not only affects the appearance, but also reduces the service life of the magnesia boards
At the same time, 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 quality of the product. quality, which limits the application of the product

Embodiment 1

[0014] Example 1 Magnesium oxide mothproof waterproof refractory board is made by mixing the following raw materials. The weight parts of each raw material are as follows: 82 parts of light burned magnesia, 28 parts of magnesium chloride, 5 parts of perlite, 12 parts of wood chips, and 6 parts of talc. 4 parts of wollastonite powder, 6 parts of camphor, 0.2 parts of mothproof essential oil, 2 parts of neoprene latex.

Embodiment 2

[0015] Example 2 Magnesium oxide mothproof waterproof refractory board is made by mixing the following raw materials. The weight parts of each raw material are as follows: 90 parts of light burned magnesia, 32 parts of magnesium chloride, 7 parts of perlite, 15 parts of wood chips, 7 parts of talcum powder, 2 parts of wollastonite powder, 8 parts of camphor, 0.5 parts of mothproof essential oil, 3 parts of neoprene latex.

Embodiment 3

[0016] Example 3 Magnesium oxide mothproof waterproof refractory board is made by mixing the following raw materials, and the weight parts of each raw material are as follows: 75 parts of light burned magnesium oxide, 27 parts of magnesium chloride, 8 parts of perlite, 12 parts of wood chips, and 5 parts of talc. 7 parts of wollastonite powder, 2 parts of camphor, 0.9 parts of mothproof essential oil, 5 parts of neoprene latex.

[0017] The above raw materials are mixed and added to the mixing equipment, mixed evenly for 20 minutes to form a magnesium oxychloride slurry, and then mechanically rolled and formed, natural curing and consolidation, demoulding, drying, cutting and shaping to form a magnesium oxide board.

Abstract

The invention discloses a mothproof waterproof magnesium oxide refractory slab. The refractory slab is prepared by mixing the following mixed raw materials in parts by weight: 72-98 parts of light calcined magnesia, 25-35 parts of magnesium chloride, 5-8 parts of perlite, 8-20 parts of wood bits, 4-8 parts of talcum powder, 1-8 parts of wollastonite powder, 1-10 parts of camphor, 0.1-1 parts of mothproof essential oil, and 2-5 parts of neoprene latex. The mothproof waterproof magnesium oxide refractory slab disclosed by the invention is quite good in halogen resistance, less in warping, deformation and cracking possibility, mothproof and quite long in service life.

Description

Technical field [0001] The invention belongs to the technical field of building materials, and in particular relates to a magnesium oxide mothproof, waterproof and refractory board. Background technique [0002] Magnesium oxide board is a new type of multifunctional building material. Because of its light weight, flexibility and reprocessing performance of wooden organic board, it also has the fire resistance and water resistance of inorganic board. It is used in walls, ceilings, floor linings and It is used in the decoration of other parts with fire protection requirements. However, the existing magnesium oxide board is often eaten by insects after a long time of use, which not only affects the appearance, but also reduces the service life of the magnesium oxide board. At the same time, the current oxide board is processed by mixing magnesium oxychloride cement and some modifiers. The fireproof board produced is susceptible to moisture and halogenation and poor whiteness. It is...
