Embodiment Construction
[0020] according to figure 1 As shown, the weight composition is: aluminum hydroxide 20-50%, magnesium hydroxide 15-45%, calcium carbonate 10-50%, perlite 1-6%, alkali-resistant fiber 2-10%, quartz powder 4- 20%, blast furnace mineral powder 5-20%, add flame retardant and glue to make inorganic fireproof core layer 2, use three-layer co-extrusion blown film equipment, blow PE or EVA and upper and lower layers of hot melt resin into a film, The thickness of the interlayer PE or EVA is 0.01-0.08mm, so that it forms a polymer film adhesive material 5 with a film thickness of 0.05-0.15mm, and the decorative coating 1, The processed and coated aluminum base material 3, the polymer film adhesive material 5, the inorganic fireproof core layer 2, the polymer film adhesive material 6 and the aluminum base material 4 are manufactured by hot pressing and continuous composite molding. Fireproof aluminum alloy composite panel.

Abstract
The invention discloses a class A fireproof aluminum alloy composite board, which is provided with a decorative coating (1) on the surface of an aluminum substrate, a processed and coated aluminum substrate (3), and an inorganic fireproof core layer ( 2) and the aluminum substrate (4), characterized in that a polymer film bonding material (5) is provided between the processed and coated aluminum substrate (3) and the inorganic fireproof core layer (2), and the inorganic fireproof A polymer film adhesive material (6) is arranged between the core layer (2) and the aluminum base material (4); PE or EVA is interposed in the middle of the molten resin layer, and the thickness of the polymer film is 0.05-0.15mm; it can reduce the cost of manufacturing composite boards, so that the hot-melt resin can be well bonded with PE or EVA, and can also be bonded with inorganic The core material is bonded firmly by hot melting, and it can also be bonded firmly with aluminum, increasing the strength and increasing the tension used, while reducing the cost, so that the composite board preparation process can achieve the purpose of continuous compounding.
Description
technical field [0001] The invention relates to a class A fireproof aluminum alloy composite board. Background technique [0002] At present, with the continuous improvement of the country's fire protection grade requirements for building decoration materials, it is stipulated that buildings with more than three floors must meet the A-level fire protection index. This kind of aluminum composite panel has reached the highest fire protection level A-level fire protection index. The use of this panel not only meets the aesthetic requirements of general decoration, but also improves the safety performance. [0003] At present, hot-melt adhesive film, also known as polymer film, is used in the production of aluminum-plastic composite panels. The plastic composite board is a structure with PE sandwiched between two aluminum boards. When the two are combined, the side of the hot melt adhesive can be bonded to the aluminum, and the other side of the PE can be fused with PE. When ma...
