[0001] This utility model relates to the field of sheet metal technology, specifically to a scratch-resistant aluminum composite panel. Background Technology
[0002] Aluminum composite panels (ACPs) are widely used in the building decoration field, especially in interior ceiling projects, due to their advantages such as lightweight, ease of processing, variety of colors, and convenient installation. However, as people's requirements for building decoration continue to increase, some problems have gradually emerged with existing ordinary ACPs. In ceiling applications, due to their insufficient scratch resistance, the surface of the panels is easily scratched by external forces such as construction tools and furniture handling during installation and daily use. This not only damages the aesthetics of the ceiling, but the scratches also accelerate the aging of the panels and shorten their service life. Summary of the Invention

This structure is simple and reliable, effectively solving the aforementioned technical problems and is suitable for widespread use. To achieve the above objectives, this utility model is implemented through the following technical solution:
[0004] A scratch-resistant aluminum composite panel includes a panel body, which comprises a wear-resistant coating, a scratch-resistant protective layer, an upper surface aluminum plate, a first polymer adhesive layer, a polymer foam core layer, a second polymer adhesive layer, and a lower surface aluminum plate. The scratch-resistant protective layer is located between the wear-resistant coating and the upper surface aluminum plate.

[0012] The outstanding and beneficial technical effects of this utility model compared with the prior art are as follows: This scratch-resistant aluminum composite panel significantly improves its scratch and wear resistance through a multi-layer composite structure design.

[0015] To make the objectives, technical solutions, and advantages of this application clearer, the technical solutions in the embodiments will be clearly and completely described below with reference to the accompanying drawings. However, the specific implementation methods and embodiments described below are for illustrative purposes only and are not intended to limit the present invention.
[0016] In the description of this utility model, it should be understood that the terms "longitudinal," "lateral," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," and "outer," etc., indicate the orientation or positional relationship based on the appendix. Figure 1 The directions or positional relationships shown are for the purpose of describing this utility model only, and are not intended to indicate or imply that the device or component referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model.
[0017] In the description of this application, the terms "first," "second," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated.
[0018] To solve the above technical problems, such as Figure 1 , 2 As shown, this utility model designs a scratch-resistant aluminum composite panel, including a panel body. The panel body includes a wear-resistant coating 1, a scratch-resistant protective layer 2, an upper surface aluminum plate 3, a first polymer adhesive layer 4, a polymer foam core layer 5, a second polymer adhesive layer 6, and a lower surface aluminum plate 7. After installation, the upper surface aluminum plate 3 faces downwards and the lower surface aluminum plate 7 is positioned above. In this panel, the outermost wear-resistant coating 1 is in direct contact with the outside environment, effectively resisting friction and wear during daily use, extending the service life of the panel, and maintaining the surface smoothness and aesthetics. The scratch-resistant protective layer 2 is located between the wear-resistant coating 1 and the upper surface aluminum plate 3, further enhancing the scratch resistance of the panel, ensuring that the surface remains intact when scratched by a sharp object, reducing the generation of scratches, and maintaining the visual effect of the panel.
[0019] The polymer foam core layer 5 is bonded to the upper surface aluminum plate 3 and the lower surface aluminum plate 7 through the first polymer adhesive layer 4 and the second polymer adhesive layer 6 on the upper and lower sides, respectively. The polymer foam core layer 5 is preferably a polyethylene foam board or a polycarbonate foam board. The polymer foam core layer 5 has a closed-cell structure. As the core part of the board, this design not only reduces the density of the board and lightens the weight, but also provides excellent thermal insulation performance, which helps to regulate indoor temperature. At the same time, its closed-cell structure enhances the water resistance and corrosion resistance of the material.
[0020] Through this multi-layer composite design, the scratch-resistant aluminum composite panel of this utility model not only has excellent scratch and wear resistance, but also good thermal insulation and structural strength. It is suitable for a variety of building decoration scenarios, especially in ceiling applications, where it performs exceptionally well. It can effectively resist wear and tear during daily use, maintain the aesthetics and functionality of the ceiling, and at the same time reduce the building's self-weight, improving construction efficiency and convenience.
[0021] In this embodiment, it is further preferred that the scratch-resistant protective layer 2 is a polyester film. Polyurethane film has excellent scratch resistance and wear resistance, which can significantly enhance the scratch resistance of the board surface, extend its service life, and maintain a certain degree of light transmittance and aesthetics.
[0022] In this embodiment, it is further preferred that the thickness of the scratch-resistant protective layer 2 is 20-100μm. A thinner scratch-resistant protective layer 2 can reduce the overall weight and cost of the material, while also reducing the impact on light transmittance.
[0023] In this embodiment, it is further preferred that the wear-resistant coating 1 is a nano-ceramic coating layer or a fluorocarbon resin layer. The nano-ceramic coating layer has extremely high hardness and wear resistance, and can form a solid protective barrier on the surface of the plate, effectively resisting various physical wear and scratches.
[0024] In this embodiment, it is further preferred that the first polymer adhesive layer 4 and the second polymer adhesive layer 6 are both modified polyolefin hot melt adhesive film layers. Modified polyolefin hot melt adhesive film layers have excellent adhesion and temperature resistance properties, and can maintain good adhesion strength over a wide temperature range, ensuring tight adhesion between the layers of the board and preventing interlayer peeling, thereby improving the stability and reliability of the entire composite structure. In addition, this hot melt adhesive film has a fast curing speed, which helps to improve production efficiency and reduce processing costs.
[0025] Considering the poor corrosion resistance of conventional panels, especially aluminum composite panels used as ceiling panels in humid environments like bathrooms or when exposed to acidic or alkaline substances, their surfaces are easily corroded, leading to panel damage. To address this issue, this embodiment further preferably includes an anti-corrosion primer coating (not shown in the figure) on the outer surfaces of the upper aluminum panel 3 and the lower aluminum panel 7. This anti-corrosion primer coating is an epoxy resin coating or a chromate coating, which can resist the erosion of various chemical substances, such as cleaning agents and disinfectants commonly used in bathrooms and other similar places. This prevents these substances from damaging the panels, maintains the integrity of the panels, prevents structural damage caused by corrosion, helps maintain the overall structural stability of the panels, ensures the safety of the ceiling during long-term use, and prevents accidents such as ceiling collapse caused by panel corrosion.
[0026] Conventional aluminum composite panels have limited structural strength and are prone to deformation during installation and use, affecting the flatness and stability of the ceiling. In this embodiment, a further preferred embodiment is that a reinforcing frame is bonded to the surface of the lower aluminum plate 7 of the main body of the panel. The reinforcing frame includes horizontal support rods 8 and vertical support rods 9. The two horizontal support rods 8 and the two vertical support rods 9 form a rectangle, creating a stable rectangular frame structure. Made of lightweight aluminum, this significantly enhances the structural strength of the panel, enabling it to withstand greater loads and pressures and preventing bending or deformation. Since the lower and upper aluminum plates 7 face upwards after installation, and the upper aluminum plate 3 faces downwards as the display surface, the reinforcing frame is hidden and does not affect the aesthetics. The cross-sections of the horizontal support rods 8 and the vertical support rods 9 are both U-shaped. The U-shaped structure significantly enhances the frame's torsional resistance. Its unique shape allows the frame to utilize its structural characteristics to prevent the panel from twisting and deforming in the horizontal plane when resisting torsion. It also reduces weight and saves costs while achieving the same reinforcement effect.
[0027] The above embodiments are merely preferred embodiments of this utility model and are not intended to limit the scope of protection of this utility model. Therefore, all equivalent changes made by those skilled in the art based on the structure, shape, and principle of this utility model should be included within the scope of protection of this utility model.
