Description

Technical Field

[0001] This utility model relates to the field of aluminum-plastic composite panel technology, and in particular to an aging-resistant aluminum-plastic composite panel. Background Technology

[0002] Traditional aluminum-plastic composite panels typically have a three-layer composite structure, with a PE core board in the middle layer and aluminum alloy plates in the upper and lower layers. The PE core board is used to achieve the composite structure of the upper and lower aluminum alloy plates, resulting in a stable structure. However, the surface has insufficient wear resistance and weather resistance.

[0003] Furthermore, most existing aluminum-plastic composite panels are solid structures, resulting in poor sound and heat insulation. Aluminum honeycomb panels can be used as a replacement in many fields. The aluminum sheet and honeycomb core of aluminum honeycomb panels are often bonded together by hot-pressing and melting a cast film at high temperatures. However, the contact area between the honeycomb core and the cast film is small, and the stability of the cast film under high-temperature exposure is not high, leading to a short lifespan for outdoor use. Improvements are needed. Utility Model Content

[0004] The purpose of this utility model is to provide an aging-resistant aluminum-plastic composite panel that improves structural stability and aging resistance, and enhances sound insulation and heat insulation effects.

[0005] To achieve this objective, the present invention adopts the following technical solution:

[0006] An aging-resistant aluminum-plastic composite panel includes: an aluminum honeycomb panel assembly, a plastic filler core, and a first protective coating. The aluminum honeycomb panel assembly includes a first aluminum skin, a honeycomb core panel, and a second aluminum skin. The first aluminum skin is disposed on the top surface of the honeycomb core panel, and the second aluminum skin is disposed on the bottom surface of the honeycomb core panel. The honeycomb core panel is densely covered with honeycomb holes. The first aluminum skin is provided with first stepped holes that communicate with some of the honeycomb holes at intervals. The plastic filler core is disposed in the honeycomb holes that communicate with the first stepped holes. The top of the plastic filler core is provided with a first stepped shaft that fills into the first stepped holes. The first protective coating is disposed on the top surface of the first aluminum skin.

[0007] The second aluminum sheet is provided with second stepped holes that correspond one-to-one with the first stepped holes, and the bottom end of the plastic filling core is provided with a second stepped shaft that fills into the second stepped holes.

[0008] The plastic filling core, the first stepped shaft, and the second stepped shaft are integrated plastic structures.

[0009] The first protective coating is a PVDF coating.

[0010] The bottom surface of the second aluminum sheet is provided with a second protective coating.

[0011] The second protective coating is a PVDF coating.

[0012] The beneficial effects of this utility model are as follows: An aging-resistant aluminum-plastic composite panel utilizes the cooperation of a plastic-filled core, a first-step shaft, and a second-step shaft to fix the first and second aluminum sheets on the top and bottom surfaces of the honeycomb core panel. It has high structural stability, good surface wear resistance and aging resistance, and retains some honeycomb pores, which can enhance the sound insulation and heat insulation effects. It has a wide range of applications. Attached Figure Description

[0014] Figure 2 yes Figure 1 Top view of the first aluminum sheet in the middle. Detailed Implementation

[0015] The following is combined with Figures 1-2 The technical solution of this utility model will be further illustrated through specific embodiments.

[0016] like Figure 1 The aging-resistant aluminum-plastic composite panel shown includes: an aluminum honeycomb panel assembly, a plastic filling core 6, and a first protective coating 4. The aluminum honeycomb panel assembly includes a first aluminum skin 1, a honeycomb core panel 3, and a second aluminum skin 2. The honeycomb core panel 3 is densely covered with honeycomb holes 31. The first aluminum skin 1 is placed on the top surface of the honeycomb core panel 3, and the second aluminum skin 2 is placed on the bottom surface of the honeycomb core panel 3, thereby sealing both ends of the honeycomb holes 31. The honeycomb holes 31 improve the overall sound insulation and heat insulation effect.

[0017] like Figure 2 As shown, first stepped holes 11 communicating with some honeycomb holes 31 are provided at intervals on the first aluminum sheet 1. The plastic filling core 6 is disposed in the honeycomb holes communicating with the first stepped holes 11. The plastic filling core 6 and the honeycomb core plate 3 work together to improve the support of the first aluminum sheet 1 and the second aluminum sheet 2, and have good impact deformation resistance.

[0018] A first stepped shaft 61 is provided at the top of the plastic filling core 3 to fill the first stepped hole 11. The first stepped shaft 61 and the first stepped hole 11 cooperate to tighten the first aluminum skin 1 and prevent the first aluminum skin 1 from separating from the honeycomb core board 3.

[0019] The first protective coating 4 is applied to the top surface of the first aluminum sheet 1. In this embodiment, the first protective coating 4 is a PVDF coating, which has good anti-wear and anti-aging effects, avoiding the corrosion and wear of the first aluminum sheet 1 during outdoor use and extending its service life.

[0020] like Figure 1As shown, the bottom surface of the second aluminum sheet 2 is provided with a second protective coating 5. In this embodiment, the second protective coating 5 is a PVDF coating, which strengthens the protection of the second aluminum sheet 2, so that the aluminum-plastic composite panel can be used on both sides and has a wide range of applications.

[0021] The second aluminum sheet 2 is provided with second stepped holes 21 that correspond one-to-one with the first stepped holes 11. The bottom end of the plastic filling core 6 is provided with a second stepped shaft 62 that fills into the second stepped holes 21. Through the cooperation of the second stepped holes 21 and the second stepped shaft 62, the second aluminum sheet 2 is tightened, and the separation of the second aluminum sheet 2 and the honeycomb core board 3 is avoided. The structure is stable and has good weather resistance.

[0022] In this embodiment, the plastic filling core 6, the first stepped shaft 61, and the second stepped shaft 62 adopt an integrated plastic structure, which can be integrally molded using PE plastic. The first aluminum sheet 1, the honeycomb core plate 3, and the second aluminum sheet 2 are stacked and placed into a mold. Molten PE plastic is injected into the corresponding honeycomb holes and the second stepped shaft 62 through the first stepped hole 11, thereby realizing the integral molding of the plastic filling core 6, the first stepped shaft 61, and the second stepped shaft 62. This results in high production efficiency and a reliable structure.

[0023] 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.
