Abstract

The invention relates to a high performance fireproof magnesite board which comprises magnesium oxide, magnesium chloride, sawdust, vermiculite, glass fiber sieve cloth, talcum powder, pearlite and water. The manufacturing process of the high performance fireproof magnesite board comprises the steps of agitating, pouring, rolling and forming, maintaining and curing, edge cutting, sanding, and inspecting and packaging. The specific process of agitating comprises 1) preparing raw materials by weight percentage; 2) setting the agitating time; and 3) adding magnesium chloride, vermiculite, glass fiber sieve cloth, talcum powder, magnesium oxide, sawdust and glue into purified water; adding pearlite at 2 minutes of countdown and discharging. The invention has the beneficial effects that the high performance fireproof magnesite board has the advantages of strong resistance to deflection, shear-resistance, shock resistance, fire prevention, no smoke spreading, no deformation after being dipped into water, moth-prevention, and mildew prevention.

Description

technical field [0001] The invention relates to building boards, in particular to a high-performance fireproof magnesite board and its manufacturing process. Background technique [0002] At present, wooden materials are commonly used for home improvement panels. Although they have advantages, they have the disadvantages of being unable to prevent fire or poor fire performance, moisture and water resistance, and need to be treated with insects. In addition, with the deterioration of human living environment, protecting forests has become an important issue. Environmental protection is the primary task of all countries in the world, so it is of great significance to replace wood materials with high-performance fire-resistant magnesite boards. Most of the existing lightweight boards on the market are composed of gypsum powder, glass fiber, resin, magnesium oxide, and additives. The mass percentage of gypsum powder is 40%-45%, and the mass percentage of glass fiber is 8%-14%. ...
