[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0021] Example: Please refer to Figures 1-3 This utility model provides a technical solution:

[0022] An antibacterial and mildew-resistant aluminum composite panel includes a panel body 1. The panel body 1 includes two sets of aluminum composite panel base layers 15, a fireproof core material 2, a cationic coating 3, an antibacterial fiber layer 4, a silver ion antibacterial coating 5, a zeolite antibacterial layer 6, and a protective layer 7. The fireproof core material 2 is bonded between the two sets of aluminum composite panel base layers 15. The cationic coating 3 is coated on the other side of the aluminum composite panel base layers 15. A connecting component is installed on the panel body 1 to connect two adjacent sets of panel bodies 1. When in use, the device can effectively improve the antibacterial effect through the cooperation between the cationic coating 3, the antibacterial fiber layer 4, the silver ion antibacterial coating 5, the zeolite antibacterial layer 6, and the protective layer 7. The structure is simple and easy to operate, effectively improving the overall antibacterial and mildew-resistant effect, reducing the possibility of bacterial growth and mold growth, and ensuring the aesthetics and structural strength of the panel body 1.

[0023] In this embodiment, as Figure 1 , Figure 2 and Figure 3As shown, the antibacterial fiber layer 4 is bonded to the side of the cationic coating 3 away from the aluminum composite panel base layer 15, and the silver ion antibacterial coating 5 is coated on the side of the antibacterial fiber layer 4 away from the cationic coating 3. Firstly, the fireproof core material 2 is a magnesium oxysulfate core material, located between the two sets of aluminum composite panel base layers 15. In the event of a fire, the magnesium oxysulfate core material possesses excellent fireproof and heat insulation properties, effectively preventing the transfer of flames and heat between the two sides of the panel. This allows the antibacterial and mildew-resistant aluminum composite panel to maintain structural integrity for a certain period when facing a fire threat, buying valuable time for personnel evacuation and fire rescue, playing a crucial role in ensuring building fire safety. The fireproof core material 2 can isolate the high temperature generated by a fire on one side, preventing it from rapidly spreading to the other side and avoiding greater harm to items and personnel on the other side.

[0024] In this embodiment, as Figure 1 , Figure 2 and Figure 3 As shown, the protective layer 7 is a nano-silver-montmorillonite composite material layer, the fireproof core material 2 is a magnesium oxysulfate core material, and the antibacterial fiber layer 4 is nano-silver fiber. Then, a cationic coating 3 is applied to one side of the aluminum composite panel base layer 15. The cationic coating 3 changes the charge distribution on the surface of the aluminum composite panel base layer 15. On the one hand, its cationic properties can interact with the negative charge on the surface of bacterial cells, interfering with the normal physiological activities of bacteria, thereby inhibiting the initial attachment of microorganisms to the surface of the panel. On the other hand, it can significantly improve the adhesion between the antibacterial fiber layer 4 and the aluminum composite panel base layer 15, ensuring the stability of the structure. The antibacterial fiber layer 4, made of nano-silver fiber, is fixed to the surface of the cationic coating 3 away from the aluminum composite panel base layer 15 by adhesive bonding. Nano-silver has strong antibacterial activity. The nano-silver in the antibacterial fiber layer 4 can interact with the cell membrane, proteins, and nucleic acids of bacteria, inhibiting or even killing bacteria and mold. Due to the properties of nano-silver fiber, the antibacterial fiber layer 4 not only gives the panel antibacterial function but also enhances the flexibility and mechanical properties of the panel.

[0025] In this embodiment, as Figure 1 , Figure 2 and Figure 3As shown, the zeolite antibacterial layer 6 is bonded to the side of the silver ion antibacterial coating 5 away from the antibacterial fiber layer 4, and the protective layer 7 is bonded to the side of the zeolite antibacterial layer 6 away from the silver ion antibacterial coating 5. Further, after thoroughly mixing silver ions with carrier materials such as epoxy resin, the mixture is uniformly coated onto the side of the antibacterial fiber layer 4 away from the cationic coating 3, forming the silver ion antibacterial coating 5. The silver ion antibacterial coating 5 further enhances the antibacterial ability of the board, comprehensively inhibiting various microorganisms through the continuous release of silver ions. Simultaneously, working synergistically with the antibacterial fiber layer 4, it can cover a wider range of microorganisms and maintain the stability of the antibacterial effect during long-term use. The zeolite antibacterial layer 6 is bonded to the side of the silver ion antibacterial coating 5 away from the antibacterial fiber layer 4. Zeolite loaded with antibacterial ions has a large specific surface area and good adsorption performance. In practical use, the zeolite antibacterial layer 6 can adsorb moisture, odors, and some harmful substances in the environment, thereby creating a favorable microenvironment for inhibiting microbial growth. Simultaneously, the antibacterial ions it carries are continuously and slowly released, working in conjunction with the silver ion antibacterial coating 5 to further enhance the long-lasting antibacterial and antifungal effect. The nano-silver-montmorillonite composite material layer, as a protective layer 7, is bonded to the side of the zeolite antibacterial layer 6 away from the silver ion antibacterial coating 5. The nano-silver-montmorillonite composite material layer not only possesses certain antibacterial and antifungal capabilities itself, but also provides a physical barrier for the various functional layers within, preventing damage to the board from external mechanical damage, chemical corrosion, and ultraviolet radiation. The layered structure of montmorillonite contributes to the uniform dispersion and stability of nano-silver, enabling it to stably exert its antibacterial and antifungal effects for a long time.

[0026] In this embodiment, as Figure 1 , Figure 2 and Figure 3As shown, the connecting assembly includes multiple sets of storage slots arranged at the bottom of the main body 1 of the sheet metal. A damping shaft is rotatably connected to one end of each storage slot. A lever 8 is fixedly sleeved on the outer side of the damping shaft. A connecting plate 9 is installed at the center of one side of the lever 8. Limiting grooves are formed on both sides of the connecting plate 9 on the outer wall of the lever 8. A limiting block 10 is slidably connected inside the limiting groove. An extension plate 11 is installed at the other end of the limiting block 10. A guide surface 12 is formed on one side of the extension plate 11. A first threaded hole is formed inside the main body 1 corresponding to the mating groove. A second threaded hole is formed inside the connecting plate 9 corresponding to the first threaded hole. The inner side of the perforated hole is connected to a fixing bolt 14. Furthermore, when it is necessary to connect adjacent plate bodies 1, the lever 8 and the damping shaft can be rotated out to connect the corresponding docking grooves and extension plates 11 on the two sets of plate bodies 1. The guide surface 12 on the extension plate 11 can retract as it abuts against the docking groove port. The extension plate 11 is pushed along with it and moves smoothly in conjunction with the limiting block 10 and the limiting groove, so that it squeezes the first spring 13 to retract until the extension plate 11 and the connecting plate 9 are completely pushed into the docking groove. The first spring 13 can hold the extension plate 11 against the inner wall of the docking groove, temporarily connecting the positions of the first threaded hole and the second threaded hole, so that the two will not be misaligned when rotating the fixing bolt 14. Then the fixing bolt 14 can be screwed into the first threaded hole and the second threaded hole to complete the docking assembly of the two sets of plate bodies 1.

[0027] The implementation principle of an antibacterial and mildew-resistant aluminum composite panel in this application embodiment is as follows: the fireproof core material 2 is a magnesium oxysulfate core material, located between two sets of aluminum composite panel base layers 15. In the event of a fire, the magnesium oxysulfate core material has good fireproof and heat insulation properties, effectively preventing the transmission of flames and heat between the two sides of the panel. This allows the antibacterial and mildew-resistant aluminum composite panel to maintain structural integrity for a certain period of time when the building faces a fire threat, buying valuable time for personnel evacuation and fire rescue, and playing a key role in ensuring building fire safety. The fireproof core material 2 can isolate the high temperature generated by the fire on one side, preventing it from spreading rapidly to the other side and avoiding greater harm to items and personnel on the other side. The cationic coating 3 is applied to one side of the aluminum composite panel base layer 15. The cationic coating 3 alters the charge distribution on the surface of the aluminum composite panel base layer 15. On one hand, its cationic properties can interact with the negative charge on the surface of bacterial cells, interfering with the normal physiological activities of bacteria and thus inhibiting the initial attachment of microorganisms to the panel surface. On the other hand, it significantly improves the adhesion between the antibacterial fiber layer 4 and the aluminum composite panel base layer 15, ensuring structural stability. The antibacterial fiber layer 4, made of nano-silver fibers, is fixed to the surface of the cationic coating 3 away from the aluminum composite panel base layer 15 by adhesive bonding. Nano-silver has strong antibacterial activity; the nano-silver in the antibacterial fiber layer 4 can interact with bacterial cell membranes, proteins, and nucleic acids, inhibiting or even killing bacteria and molds. Due to the properties of nano-silver fibers, the antibacterial fiber layer 4, while giving the panel antibacterial function, also enhances the panel's flexibility and mechanical properties. After thoroughly mixing silver ions with carrier materials such as epoxy resin, it is uniformly coated on the side of the antibacterial fiber layer 4 away from the cationic coating 3, forming a silver ion antibacterial coating 5. The silver ion antibacterial coating 5 further enhances the panel's antibacterial ability by continuously releasing silver ions, comprehensively inhibiting various microorganisms. Simultaneously, working synergistically with the antibacterial fiber layer 4, it can cover a wider range of microorganisms and maintain the stability of its antibacterial effect during long-term use. The zeolite antibacterial layer 6 is bonded to the side of the silver ion antibacterial coating 5 away from the antibacterial fiber layer 4. Zeolite loaded with antibacterial ions has a large specific surface area and good adsorption performance. In practical use, the zeolite antibacterial layer 6 can adsorb moisture, odors, and some harmful substances in the environment, thus creating a favorable microenvironment for inhibiting microbial growth. At the same time, the antibacterial ions it loads are continuously and slowly released, working in conjunction with the silver ion antibacterial coating 5 to further enhance the long-term antibacterial and antifungal effect. The nano-silver-montmorillonite composite material layer, as a protective layer 7, is bonded to the side of the zeolite antibacterial layer 6 away from the silver ion antibacterial coating 5. The nano-silver-montmorillonite composite material layer not only possesses certain antibacterial and antifungal capabilities itself, but also provides a physical barrier for the internal functional layers, preventing damage to the board from external mechanical damage, chemical corrosion, and ultraviolet radiation.The layered structure of montmorillonite helps to ensure the uniform dispersion and stability of nano-silver, enabling it to exert its antibacterial and antifungal effects stably for a long time. When it is necessary to connect adjacent plate bodies 1, the lever 8 and damping shaft can be rotated out to connect the corresponding docking grooves and extension plates 11 on the two sets of plate bodies 1. The guide surface 12 on the extension plate 11 can retract as it abuts against the port of the docking groove, and the extension plate 11 is pushed along with it. With the help of the limiting block 10 and the limiting groove, it moves smoothly and compresses the first spring 13 to retract until the extension plate 11 and the connecting plate 9 are completely pushed into the docking groove. The first spring 13 can hold the extension plate 11 against the inner wall of the docking groove, temporarily connecting the positions of the first threaded hole and the second threaded hole to prevent misalignment when rotating the fixing bolt 14. Then, the fixing bolt 14 can be screwed into the first threaded hole and the second threaded hole to complete the docking assembly of the two sets of plate bodies 1.
