[0029] See also Figure 1-5 The metal core composite decorative panel includes an aluminum honeycomb core panel 1, and metal plates 2 are bonded on both sides of the aluminum honeycomb core panel 1; in some embodiments, the metal plate 2 can be an aluminum plate or a steel plate; in this embodiment, the metal plate 2 is an aluminum plate.

[0030] The aluminum honeycomb core panel 1 and the metal panels 2 on both sides thereof form a metal core having a certain thickness and being lighter in weight than pure aluminum panels of the same thickness.

[0031] The outer side of the metal plate 2 is bonded with a veneer layer 3. In this embodiment, the veneer layer 3 is preferably made of Phoebe nanmu. Phoebe nanmu is a precious wood material with the characteristics of being beautiful, solid and durable. It is also widely used in traditional interior decoration panels and furniture and has good cultural and ornamental value.

[0032] In this embodiment, the outer sides of the veneer layer 3 are coated with a paint layer, which is not shown in the figure; the paint layer can protect the surface of the golden nanmu and increase its aesthetics.

[0033] Since the aluminum honeycomb core panel 1 has uniform hexagonal mesh holes, the bonding area between the metal plate 2 and the aluminum honeycomb core panel 1 is small, which limits the improvement of the bonding strength. Therefore, in this embodiment, a number of reinforcements 4 are bonded between the metal plates 2 on both sides of the aluminum honeycomb core panel 1, and the span of the reinforcements 4 is the same as the thickness of the aluminum honeycomb core panel 1. The reinforcements 4 are evenly arranged and pass through the mesh holes of the aluminum honeycomb core panel 1; this significantly increases the bonding area of ​​the metal plate 2, enhances the integrity, and improves the connection strength.

[0034] In this embodiment, the reinforcement 4 includes an intermediate body 41 and two connecting bodies 42. The connecting body 42 is in the shape of a flat plate. The two connecting bodies 42 are fixedly connected to the two ends of the intermediate body 41 to make the reinforcement 4 in an I-shape. The two connecting bodies 42 are respectively bonded to the metal plates 2 on both sides of the aluminum honeycomb core panel 1; in this embodiment, the material of the reinforcement 4 is aluminum, and the reinforcement 4 can be formed by using an aluminum profile with an I-shaped cross-section and cutting it.

[0035] Production process: cut and shape two metal plates 2 of the same size, and evenly apply glue on one side of the two metal plates 2;

[0036] Cut and shape an aluminum honeycomb core panel 1 with a size matching that of the metal plate 2, and stick the aluminum honeycomb core panel 1 to the glue-coated side of the metal plate 2;

[0037] A plurality of reinforcement members 4 are evenly placed in the grid holes of the aluminum honeycomb core panel 1;

[0038] The glue-coated side of another metal plate 2 is pressed against the other side of the aluminum honeycomb core plate 1 for pressing and bonding;

[0039] Brush glue on the outside of the metal plate 2, and press and stick the veneer layer 3; thus, a glue layer 5 is formed between the veneer layer 3 and the metal plate 2, and between the metal plate 2 and the aluminum honeycomb core plate 1;

[0040] Finally, paint is applied to the outside of the veneer layer 3 to form a paint layer.

[0041] Specific embodiment 2 of the metal core composite decorative panel provided by the utility model:

[0042] See also Figure 6 The difference between this embodiment and embodiment 1 is that in embodiment 1, the shape of the connector 42 is a flat plate, while in this embodiment, both ends of the connector 42 are provided with bending portions 421, so that the shape of the connector 42 is U-shaped, the U-shaped openings of the two connectors 42 of the reinforcement 4 are opposite, and the outer side of the bending portion 421 is bonded to the inner wall of the grid hole of the aluminum honeycomb core panel 1.

[0043] The bending portion 421 can be attached to the inner side of the grid hole of the aluminum honeycomb core panel 1; during the production process, the outer side of the bending portion 421 also needs to be coated with glue. After the glue is cured, the reinforcement 4 is bonded to the aluminum honeycomb core panel 1, further improving the connection strength of the composite decorative panel.

[0044] Finally, it should be noted that the above is only a preferred embodiment of the utility model and is not intended to limit the utility model. Although the utility model is described in detail with reference to the above embodiments, those skilled in the art can still modify the technical solutions recorded in the above embodiments without creative work, or replace some of the technical features therein with equivalents.
