Description

Technical Field

[0001] This application relates to the field of aluminum composite panel technology, specifically a corrosion-resistant aluminum composite panel. Background Technology

[0002] Aluminum single-layer panels, as a high-quality decorative material, are widely used in the construction field due to their unique properties, becoming an important choice for beautifying the appearance of buildings.

[0003] An existing patent (publication number: CN222009348U) discloses a corrosion-resistant aluminum panel, including an aluminum panel. A connector is rotatably installed on the right end of the aluminum panel. A glass plate is slidably installed on the inner side of the stop. An upper sliding strip is slidably installed on the upper end of the aluminum panel. A positioning hole is provided at the lower center of the aluminum panel to fix a fixing plate to a wall or steel structure. A sealing ring is installed on the back frame plate of the aluminum panel. The mounting parts on the back frame plate are hung on the U-shaped parts. Similarly, other aluminum panels are placed side by side. After the connector is flipped, it engages with the left groove on the adjacent aluminum panel, thereby causing the sealing ring to squeeze and seal the gap. The positioning screw is inserted into the positioning hole to complete the quick installation of the aluminum panel. After squeezing the upper sliding strip, the glass plate is inserted into the stop. Under the action of the spring, the upper sliding strip automatically pops outward to seal the glass plate. With the help of the anti-corrosion layer, the corrosion resistance of the aluminum panel can also be improved. This set of aluminum panels has strong corrosion resistance and is easy to install.

[0004] The aforementioned comparative document points out that the anti-corrosion layer on aluminum panels is prone to cracking or peeling due to exposure to corrosive environments and temperature changes, resulting in corrosion and damage to appearance and performance. It also mentions using glass panels to improve the corrosion resistance of aluminum panels. To further optimize the corrosion resistance of aluminum panels, a corrosion-resistant aluminum panel is proposed. Utility Model Content

[0005] To address the shortcomings of existing technologies, this application provides a corrosion-resistant aluminum panel with a corrosion-resistant coating on the surface of the aluminum panel, which further optimizes the corrosion resistance of the aluminum panel and enables the glass panel to be tightly attached to the aluminum panel when fixing the glass panel, avoiding gaps between the glass panel and the aluminum panel, optimizing the protective effect of the glass panel, and thus improving the overall corrosion resistance of the aluminum panel.

[0006] To achieve the above objectives, this application provides the following technical solution: a corrosion-resistant aluminum panel, comprising a building body, an aluminum panel on the front of the building body, a frame fixedly connected to the back of the aluminum panel, a corrosion-resistant coating on the front of the aluminum panel, the corrosion-resistant coating comprising a nano-zinc oxide coating, a graphene-reinforced epoxy resin coating, and a fluorocarbon ceramic composite coating, a glass panel on the front of the aluminum panel, four expansion bolts fixedly connected inside the building body, four first mounting holes opened inside the aluminum panel, the aluminum panel slidingly engaging with the expansion bolts through the first mounting holes, four mounting frames fixedly connected inside the glass panel, each mounting frame having a second mounting hole opened inside, the mounting frame slidingly engaging with the expansion bolts through the second mounting holes, and a nut threadedly connected to the outer circumference of each expansion bolt.

[0007] The above solution further optimizes the corrosion resistance of aluminum panels by coating them with a corrosion-resistant coating consisting of a nano zinc oxide coating, a graphene-reinforced epoxy resin coating, and a fluorocarbon ceramic composite coating. By using expansion bolts and nuts to install and position the aluminum and glass panels, the glass panels can be tightly attached to the aluminum panels, avoiding gaps between them. This optimizes the protective effect of the glass panels on the aluminum panels and the corrosion-resistant coating, thereby improving the overall corrosion resistance of the aluminum panel.

[0008] Furthermore, the nano zinc oxide coating, the graphene-reinforced epoxy resin coating, and the fluorocarbon ceramic composite coating are sequentially coated on the outer surface of the aluminum panel.

[0009] Through the above methods, nano zinc oxide exhibits excellent antibacterial, UV-resistant, and corrosion-resistant properties. It can absorb and scatter ultraviolet rays, effectively preventing UV damage to aluminum panels. Simultaneously, its antibacterial properties help maintain the cleanliness of the aluminum panel surface, reducing the risk of corrosion caused by microbial growth. Graphene, as a novel nanomaterial, possesses extremely high strength and conductivity. Combining it with epoxy resin can significantly improve the mechanical strength and corrosion resistance of the coating. The addition of graphene also enhances the coating's adhesion and wear resistance, extending its service life. The fluorocarbon ceramic composite coating combines the weather resistance of fluorocarbon resin with the high hardness and wear resistance of ceramic materials. This coating can maintain its vibrant color for a long time, resist fading, and withstand various harsh environmental conditions, such as high temperature, low temperature, and humidity.

[0010] Furthermore, the mounting frame is made of hard metal, and the outer surface of the mounting frame is coated with an anti-rust coating.

[0011] The above solution uses a hard metal frame to ensure sufficient strength and stability, resisting deformation and damage, and ensuring the safe installation of the glass panel. Applying an anti-rust coating to the outer surface of the frame can further improve its corrosion resistance. The anti-rust coating can isolate moisture and oxygen, prevent the frame from rusting and corroding, and extend its service life.

[0012] Furthermore, a sealing strip is fixedly connected to the back edge of the glass plate, and the back of the sealing strip is in close contact with the front of the aluminum panel.

[0013] By fixing a sealing strip to the back edge of the glass panel using the above method, a tight contact between the glass panel and the aluminum panel can be ensured. The sealing strip can isolate moisture and dust, preventing them from entering the installation gap, thereby optimizing the protective effect on the corrosion-resistant coating. At the same time, the sealing strip can also provide a certain buffering effect, reducing the risk of glass panel breakage caused by external forces.

[0014] Furthermore, each of the expansion bolts has a washer slidably fitted onto its outer circumferential surface, and the washer is located between the mounting frame and the nut.

[0015] The above solution increases the contact area between the mounting frame and the nut, disperses pressure, prevents the nut from loosening or damaging the mounting frame, and also provides some vibration isolation, reducing noise and damage risks caused by vibration.

[0016] Furthermore, each of the expansion bolts has a decorative cover threaded onto its outer circumferential surface, and the nut is located inside the decorative cover.

[0017] The above solution allows the decorative cover to conceal the expansion bolts and nuts, improving the overall aesthetics. The decorative cover also provides some protection, preventing the expansion bolts and nuts from being exposed to the outside environment and corroded.

[0018] Furthermore, a sealing ring is fixedly connected to the back of the decorative cover, and the back of the sealing ring is in close contact with the front of the mounting frame.

[0019] Through the above solution, the sealing ring can isolate moisture and dust, preventing them from entering the interior of the decorative cover, thereby keeping the installation area dry and clean, and avoiding corrosion of the expansion bolts and nuts by rainwater, etc.

[0020] Furthermore, the back of the aluminum panel is fixedly connected with reinforcing ribs, which are arranged in a grid pattern.

[0021] By fixing reinforcing ribs to the back of the aluminum panel using the above method, the strength and rigidity of the aluminum panel can be increased. The reinforcing ribs are arranged in a grid pattern, which can evenly distribute the external force and prevent the aluminum panel from deforming or being damaged due to excessive force.

[0022] Compared with the prior art, the technical solution of this application has the following beneficial effects:

[0023] This corrosion-resistant aluminum panel further optimizes the corrosion resistance of the aluminum panel by coating its surface with a corrosion-resistant coating consisting of a nano zinc oxide coating, a graphene-reinforced epoxy resin coating, and a fluorocarbon ceramic composite coating. By using expansion bolts and nuts to install and position the aluminum panel and glass panel, the glass panel can be tightly attached to the aluminum panel, avoiding gaps between the glass panel and the aluminum panel. This optimizes the protective effect of the glass panel on the aluminum panel and the corrosion-resistant coating, thereby improving the overall corrosion resistance of the aluminum panel.

[0041] In this embodiment, a corrosion-resistant aluminum panel 2 is further optimized by coating the surface of the aluminum panel 2 with a corrosion-resistant coating 4 composed of a nano zinc oxide coating 401, a graphene-reinforced epoxy resin coating 402, and a fluorocarbon ceramic composite coating 403. By using expansion bolts 6 and nuts 10 to install and position the aluminum panel 2 and the glass panel 5, the glass panel 5 can be tightly attached to the aluminum panel 2, avoiding gaps between the glass panel 5 and the aluminum panel 2, thus optimizing the protective effect of the glass panel 5 on the aluminum panel 2 and the corrosion-resistant coating 4, and thereby improving the overall corrosion resistance of the aluminum panel 2.

The graphene-reinforced epoxy resin coating 402 significantly improves the mechanical strength and corrosion resistance of the coating, enhances its adhesion and wear resistance, thereby extending the service life of the coating. The fluorocarbon ceramic composite coating 403 combines the weather resistance of fluorocarbon resin with the high hardness and high wear resistance of ceramic materials, enabling the coating to maintain its properties for a long time. With vibrant colors that resist fading and withstand corrosion from various harsh environments, the aluminum panel's corrosion resistance is further optimized. Both the aluminum panel 2 and the glass panel 5 are installed and positioned using expansion bolts 6 and nuts 10. The expansion bolts 6 pass through the first mounting hole 7 of the aluminum panel 2 and the second mounting hole 9 of the mounting frame 8 of the glass panel 5, and are fixedly connected to the building body 1. The nuts 10 are tightened onto the expansion bolts 6, firmly fixing the aluminum panel 2 and the glass panel 5 to the building body 1, ensuring a tight contact between the glass panel 5 and the aluminum panel 2, and avoiding gaps. At the same time, the sealing strip 11 on the back edge of the glass panel 5 effectively isolates moisture and dust, preventing them from entering the installation gaps, optimizing the protective effect of the glass panel 5 on the aluminum panel 2 and the corrosion-resistant coating 4, thereby improving the overall corrosion resistance of the aluminum panel.
