Description

Technical Field

[0001] This utility model relates to the field of composite board technology, and in particular to a hot-pressed composite board that is easy to assemble. Background Technology

[0002] To achieve the composite between the core board and the surface layer made of the same or different materials, hot melt adhesive can be added between the core board and the surface layer. The hot melt adhesive is melted by hot pressing and then cooled to form a hot-pressed composite board of a certain thickness, thereby improving the utilization rate of materials and the functionality of the hot-pressed composite board.

[0003] Since the area of ​​a single hot-pressed composite panel is limited, multiple panels are usually assembled for use. Assembly of adjacent hot-pressed composite panels can be achieved using glue, mortise and tenon joints, or installation connectors. However, applying glue on-site is slow, and the lack of planar constraints between panels results in poor assembly accuracy. Mortise and tenon joints are often exposed, affecting the surface aesthetics of the hot-pressed composite panel. Installing connectors requires screws, which damages the structure of the hot-pressed composite panel and is inefficient; these methods need improvement. Utility Model Content

[0020] The following is combined with Figures 1-4 The technical solution of this utility model will be further illustrated through specific embodiments.

[0021] like Figure 1The hot-pressed composite panel shown is easy to assemble and includes: a first honeycomb core panel 1, a second honeycomb core panel 2, a first decorative layer 10, a second decorative layer 14, and a first adhesive layer 7. The first honeycomb core panel 1 is arranged parallel above the second honeycomb core panel 2 and provides heat insulation through the honeycomb structure, thereby improving the heat preservation effect of the hot-pressed composite panel.

[0022] A first extension 5 is provided at the front end of the first honeycomb core board 1, extending to the upper front side of the second honeycomb core board 2, and a second extension 4 is provided at the rear end of the second honeycomb core board 2, extending to the lower rear side of the first honeycomb core board 1. During the assembly process, the first extension 5 and the second extension 4 of the two adjacent hot-pressed composite boards are cross-composite.

[0023] In this embodiment, the first honeycomb core panel 1 and the first extension 5 adopt an integrated structure, and the second honeycomb core panel 2 and the second extension 4 adopt an integrated structure. Both can be made of aluminum honeycomb core panels, which are lightweight.

[0024] An upwardly extending positioning pin 3 is provided in the second extension 4, such as... Figure 2 As shown, the positioning pin 3 is directly inserted into the honeycomb hole of the second extension 4, which is simple to operate. During the assembly of the front and rear hot-pressed composite plates, the positioning pin 3 is engaged with the honeycomb hole in the first extension of the rear hot-pressed composite plate to limit the position of the two adjacent hot-pressed composite plates, thereby improving the assembly accuracy and structural stability.

[0025] In addition, such as Figure 4 As shown, a layer of pressure-sensitive adhesive 6 is provided on the top of the second extension 4. The pressure-sensitive adhesive 6 is used to bond the first extension and the second extension of two adjacent hot-pressed composite plates, thereby improving the structural stability after assembly. In this embodiment, the pressure-sensitive adhesive 6 is provided with through holes corresponding to the positioning pins 3, which does not affect the installation of the positioning pins 3.

[0026] like Figure 3 As shown, the first adhesive layer 7 is disposed between the first honeycomb core panel 1 and the second honeycomb core panel 2. In this embodiment, the first adhesive layer 7 is a hot melt adhesive, which melts during hot pressing to bond the first honeycomb core panel 1 and the second honeycomb core panel 2. A first fiber mesh 11 is embedded in the first adhesive layer 7. The first fiber mesh 11 is made of glass fiber mesh or nylon mesh. The first fiber mesh 11 not only improves the overall structural stability, but also reduces the amount of hot melt adhesive flowing into the honeycomb cells of the first honeycomb core panel 1 and the second honeycomb core panel 2 after the first adhesive layer 7 melts. This allows a small amount of hot melt adhesive to flow into the first honeycomb core panel 1 and the second honeycomb core panel 2, which improves the bonding stability of the first honeycomb core panel 1 and the second honeycomb core panel 2, and also ensures the thermal insulation effect of the first honeycomb core panel 1 and the second honeycomb core panel 2.

[0027] The first decorative layer 10 is disposed above the first honeycomb core panel 1, and the second decorative layer 14 is disposed below the second honeycomb core panel 2. In this embodiment, the first decorative layer 10 and the second decorative layer 14 are respectively made of wood grain paper, providing a wood grain-like appearance with good aesthetics.

[0028] A second adhesive layer 8 is provided between the first decorative layer 10 and the first honeycomb core board 1, and a third adhesive layer 9 is provided between the second honeycomb core board 2 and the second decorative layer 14. In this embodiment, the second adhesive layer 8 and the third adhesive layer 9 are respectively made of hot melt adhesive, and the first decorative layer 10 and the second decorative layer 14 are fixed by hot pressing process.

[0029] like Figure 2 As shown, a second fiber mesh 12 is embedded in the second adhesive layer 8, and a third fiber mesh 13 is embedded in the third adhesive layer 9. The second fiber mesh 12 and the third fiber mesh 13 are both made of glass fiber mesh or nylon mesh, which can improve the stability of the second adhesive layer 8 and the third adhesive layer 9, provide more stable support for the first finishing layer 10 and the second finishing layer 14, and have good impact resistance.

[0030] The above description is only a preferred embodiment of this utility model. For those skilled in the art, there will be changes in the specific implementation method and application scope based on the idea of ​​this utility model. The content of this specification should not be construed as a limitation of this utility model.
