Fireproof aluminum-magnesium plate

Abstract

The invention discloses a fireproof aluminum-magnesium plate. The fireproof aluminum-magnesium plate comprises a base plate, a multi-layer composite structure is further arranged on the base plate, and the multi-layer composite structure sequentially comprises a bonding layer, a heat insulation layer and a heat insulation panel, wherein the bonding layer covers the surface of the base plate and used for reinforcing adhesive force; the heat insulation layer covers the surface of the base plate and used for insulating heat and preserving heat; the heat insulation panel is arranged on the surfaceof the heat insulation layer and used for protecting the plate, preventing fires and retarding inflaming; the heat insulation layer is filled with 2-3 mm inorganic heat preservation mortar; the baseplate is an aluminum-magnesium plate, the heat insulation panel is an HIP (heat insulation plate), the heat insulation panel is covered with sintered color sand, and the bonding layer is mainly prepared from compound acrylic resin. The heat insulation layer filled with the inorganic heat preservation mortar and the heat insulation panel covered with the HIP are arranged on the aluminum-magnesium plate, and through compounding with the aluminum-magnesium base plate, double-layer fire prevention and heat insulation are achieved, the plate is firm, can resist wind pressure, and is high in impactresistance and long in service life.

Description

technical field [0001] The invention relates to the technical field of building materials, in particular to a fireproof aluminum-magnesium plate. Background technique [0002] The main element of aluminum-magnesium sheet is aluminum, and a small amount of magnesium or other metal materials are added to strengthen its hardness. The main features are low density, high tensile strength, high elongation, and the weight of aluminum-magnesium sheet is lower than other sheets under the same area. Therefore, it is commonly used in aviation, such as aircraft fuel tanks, and is also widely used in conventional industries. [0003] The aluminum-magnesium plate is light in weight, good in heat dissipation, strong in pressure resistance, high in corrosion resistance, and has outstanding thermal conductivity and strength, which can fully meet the needs of highly integrated, thinner, miniaturized, and drop-resistant 3C products. Collision and electromagnetic shielding and heat dissipatio...
