Detailed ways

Fig. 1 shows the front view of the composite panel. The composite panel includes a frame 11 made of square side beams. The frame 11 includes a frame 13 and a cavity with a plurality of holes that separate the cavity of the frame into several small cavities. Square longitudinal beams 12 and crossbeams 14 are filled with core boards 10 in the small cavity, and the side beams, crossbeams 14, longitudinal beams 12 and core boards 10 constitute the middle laminate of the composite board, and the middle laminate of the The two sides are covered with thin metal sheets 9 by bonding.

Fig. 2 is the cross-sectional view of the composite panel, the composite panel is made up of panel 19, aluminum alloy frame side beam 15, middle beam 18 and polystyrene plate 17 filled in the middle, panel 19, aluminum alloy frame and polystyrene panel filled in the middle The plate 17 is bonded by the upper and lower surface adhesive layers 16, 21, the upper surface thin steel plate 19 is a colored steel plate, the lower surface steel plate 20 is a galvanized steel plate, and the upper surface thin steel plate can also be an ordinary strength steel plate, an extra high strength steel plate, an aluminum plate, Stainless steel plate, FRP plate, etc., the steel plates on the inner and outer surfaces can be made of the same material, or two of the above-mentioned plates can be used in combination according to needs. The material filled in the aluminum alloy frame can use high-density, medium-density and low-density polystyrene boards according to the different requirements for the strength of the composite board. The thickness of the polystyrene board is the same as that of the aluminum alloy frame, but The thickness tolerance of the polystyrene board is positive to ensure that the upper and lower panels are in full contact with the surface of the aluminum alloy frame and the surface of the polystyrene board when the bonding is completed, so as to ensure that the bonding surfaces are completely bonded together. The adhesive of the adhesive layer adopts a one-component polyurethane adhesive, or other types of higher-strength adhesives. After the panel and the core board are bonded, heat-compression lamination or lamination at room temperature and pressure is carried out.
