detailed description

The utility model provides an aluminum non-combustible composite board. In order to make the purpose, technical scheme and effect of the utility model clearer and clearer, the utility model is further described in detail with reference to the accompanying drawings and examples. It should be understood that the specific embodiments described here are only used to explain the utility model, and are not intended to limit the utility model.

An aluminum non-combustible composite panel as shown in Figure 1, which includes an inorganic core material layer 100, the upper and lower surfaces of the inorganic core material layer are respectively covered with a polymer film layer 200 and an aluminum alloy thin plate layer 300, wherein, The inorganic core material layer is a palm environmental protection board layer. Preferably, the palm environmental protection board layer is a palm fiber inorganic board layer. Inorganic core material layer adopts palm fiber inorganic plate layer so that the utility model composite board has excellent thermal insulation performance, because the thermal conductivity of palm fiber inorganic plate layer is low, so the thermal insulation performance of the palm fiber inorganic plate layer is excellent, making this utility model The practical new aluminum non-combustible composite board does not need to add an additional insulation layer as a decorative board, so it has a strong competitive advantage compared with similar products in the market.

At the same time, the inorganic board layer of palm fiber is an inorganic material, so that the fire protection grade of the aluminum non-combustible composite board of the utility model reaches A grade, which can meet the increasingly stringent requirements of building fire protection grade, and adapt to the development trend of future building decoration materials.

The palm fiber inorganic board layer also has the characteristics of low water absorption, so that the aluminum non-combustible composite board of the utility model has excellent waterproof and moisture-proof performance, and the strong weather resistance can help the aluminum non-combustible composite board to have a longer service life. In order to ensure thermal insulation and decorative effects, the thickness of the palm environmental board layer is 3-30mm.

Further, the polymer film layer is an aluminothermic composite polymer adhesive film layer. Since the aluminum non-combustible composite board of the utility model adopts the palm fiber inorganic board layer as the core material, it is necessary to use the aluminothermic composite polymer adhesive film layer as the bonding layer to firmly bond the aluminum alloy thin board layer and the palm fiber inorganic board layer together to avoid cracking problems between the two. Preferably, the polymer film layer has a thickness of 0.06-0.15 mm. The polymer film layer within this thickness range can provide the strongest connection strength between the aluminum alloy thin plate layer and the palm fiber inorganic plate.

Preferably, the thickness of the aluminum alloy sheet layer is 0.1-0.6 mm. The aluminum alloy thin plate layer within this thickness range can take into account the decoration and the overall strength of the composite board. The aluminum alloy thin plate layer can not only provide support strength for the composite board as a whole, ensure that the aluminum non-combustible composite board does not deform, but also adapt to the adhesion of the polymer film layer. The joint strength ensures the tightness of the connection of each layer of the aluminum non-combustible composite panel.

In a preferred embodiment, the surface of the aluminum alloy sheet layer is provided with a decorative coating 400 . The decorative coating is specifically a coated aluminum coil layer, so the aluminum non-combustible composite panel of the utility model can select different decorative coatings according to needs, thereby achieving different decorative effects.

In order to realize the continuous production of the aluminum non-combustible composite board of the present invention on the production line, the pressing condition of the aluminum non-combustible composite board is: under the temperature of 120-250 ° C, the pressure flat machine applies a pressure of 0.4-0.6 mpa/c㎡ and maintains 1- 10 minutes. The aluminothermic composite polymer bonding film layer with a thickness of 0.06-0.15mm can give full play to its excellent bonding characteristics under the above-mentioned pressing conditions, thereby realizing efficient continuous production while ensuring the product quality of aluminum non-combustible composite panels.

The utility model discloses an aluminum non-combustible composite board. The fireproof grade of the composite board reaches Class A, which meets the needs of buildings with high fireproof grade requirements. Therefore, it has a strong competitive advantage compared with the composite boards on the market. It has the characteristics of low thermal conductivity and low water absorption, so the aluminum non-combustible composite board of the utility model also has excellent thermal insulation performance and waterproof and moisture-proof function.
