Embodiment Construction

[0017] The present invention will now be described in further detail in conjunction with the accompanying drawings and preferred embodiments. These drawings are all simplified schematic diagrams, which only illustrate the basic structure of the present invention in a schematic manner, so they only show the configurations related to the present invention.

[0018] like figure 1 A kind of aluminum-magnesium-calcium composite board shown comprises upper and lower two-layer aluminum boards 1 as the surface layer, and a fireproof layer 3 is arranged between the two layers of aluminum boards 1; the fireproof layer 3 is composed of magnesium hydroxide, calcium powder, It is made by mixing and calendering glass fiber and inorganic glue, and the mass percentage of each substance is 34% magnesium hydroxide, 60% calcium powder, 4% glass fiber, and 2% inorganic glue.

[0019] The invention replaces the interlayer of plastic products in the middle of the traditional aluminum-plastic board...

Abstract

The invention relates to an aluminum-magnesium-calcium composite plate. The aluminum-magnesium-calcium composite plate comprises an upper layer of aluminum plates and a lower layer of aluminum plates, and the upper layer of aluminum plates and the lower layer of aluminum plates are used as the surface layers; a fire protection layer is placed between the two layers of aluminum plates; and the fire protection layer is formed by mixing and calendaring magnesium hydrate, calcium powder, glass fibers and inorganic glue. The aluminum-magnesium-calcium composite plate adopts magnesium-based inorganic A1-level fire proofing material, so that greater performances on fire proofing and water proofing are brought; the aluminum-magnesium-calcium composite plate is high in bending and impacting resistance, and has the combustion performance meeting national A-level standard and the smoke toxicity reaching safety level AQ1 which are both the highest levels on fire proofing and smoke toxicity.

Description

technical field [0001] The invention relates to a composite board, in particular to an aluminum-magnesium-calcium composite board with extremely high fireproof performance. Background technique [0002] Composite board refers to a layer of board covered with another layer of board to achieve the effect of increasing mechanical strength and reducing costs. At present, the widely used composite panels include metal composite panels, wood composite panels, color steel composite panels and rock wool composite panels. Among them, taking metal composite panels as an example, aluminum-plastic panels are commonly used in the market at present, that is, three-layer composite panels with aluminum panels on both sides and polyethylene in the middle layer made by coating, extrusion, bonding and other methods. It is generally coated and mainly used as a decorative material. However, because the middle layer is made of polyethylene, it is lacking in fire resistance and cannot meet the n...
