[0021] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0022] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0023] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that excludes other embodiments.

[0024] Example

[0025] Reference Figures 1-4 This is an embodiment of the present invention, which provides a temperature-controlled color-changing aluminum composite panel coating structure, including:

[0026] Mounting frame 101, a slot 102 provided on one side of mounting frame 101, a tenon 103 fixedly installed on the other side of mounting frame 101, a base plate 104 fixedly connected to the inner wall of mounting frame 101, a reinforcing rib 105 fixedly installed in the inner cavity of base plate 104, and a coating assembly 106 provided on the surface of base plate 104.

[0027] Specifically, the coating assembly 106 includes a base coating 106a coated on the surface of the substrate 104, and a temperature-controlled color-changing layer 106b bonded to the surface of the base coating 106a. The coating assembly 106 also includes a protective layer 106c coated on the surface of the temperature-controlled color-changing layer 106b, and an anti-fouling layer 106d thermally bonded to the surface of the protective layer 106c.

[0028] Furthermore, the base coating 106a is made of epoxy resin material, and the thickness of the base coating 106a is 1mm-2mm. The epoxy resin material has good adhesion and corrosion resistance, and can effectively protect the substrate 104 from the erosion of the external environment.

[0029] Preferably, the thermochromic layer 106b is made of thermochromic dye, and the color-changing temperature range of the thermochromic layer 106b is -10℃ to 80℃. The thermochromic dye can change color when the temperature changes, so that the aluminum composite panel presents different colors at different temperatures, which has a better decorative effect and temperature indication function.

[0030] It should be noted that the protective layer 106c is made of polyurethane material, and the thickness of the protective layer 106c is set to 2mm-4mm. Polyurethane material has excellent wear resistance and impact resistance, which can effectively protect the temperature-controlled color-changing layer 106b from mechanical damage. The anti-fouling layer 106d is made of nano-silica material, and the thickness of the anti-fouling layer 106d is set to 1mm-3mm. Nano-silica material has superhydrophobicity and self-cleaning function, which can effectively prevent dirt from adhering and keep the surface of the aluminum composite panel clean.

[0031] During use, when splicing aluminum composite panels, the mounting frame 101 has a slot 102 on one side and a tenon 103 on the other side. The slot 102 and tenon 103 work together to achieve quick installation and secure connection of the aluminum composite panels. A reinforcing rib 105 is fixedly installed inside the base plate 104, enhancing the overall structural strength and stability and preventing deformation or damage to the aluminum composite panels during installation or use. When the ambient temperature changes, the thermochromic dye in the thermochromic layer 106b senses the temperature change. The molecular structure of the thermochromic dye changes with the temperature, causing a change in its optical properties, and the color of the thermochromic layer 106b changes accordingly. The base coating 1 is made of epoxy resin material. 06a, tightly coated on the surface of substrate 104, epoxy resin has excellent adhesion and corrosion resistance, effectively isolating external moisture, acids, alkalis and other corrosive substances, preventing substrate 104 from being eroded; protective layer 106c made of polyurethane material is coated on the surface of temperature-controlled color-changing layer 106b, polyurethane material has high wear resistance and impact resistance, can absorb external friction, collision and other mechanical forces, and avoid damage to temperature-controlled color-changing layer 106b; anti-fouling layer 106d is made of nano-silica material, hot-melt bonded to the surface of protective layer 106c, when rainwater or cleaning water flows over the surface, water droplets will quickly roll off and carry away surface dust and dirt, keeping the aluminum composite panel surface clean and reducing cleaning and maintenance costs.

[0032] In summary, the aluminum composite panel is quickly installed and securely connected by the slot 102 and tenon 103 of the mounting frame 101. Meanwhile, the reinforcing ribs 105 inside the substrate 104 enhance the overall structural strength and stability, preventing deformation or damage. The thermochromic dye in the temperature-controlled color-changing layer 106b senses changes in ambient temperature and changes color through molecular structure, giving the aluminum composite panel dynamic decorative and temperature indication functions. The epoxy resin base coating 106a adheres tightly to the surface of the substrate 104, providing excellent corrosion resistance, isolating external erosion, and extending service life. The polyurethane protective layer 106c covers the temperature-controlled color-changing layer 106b, absorbing external mechanical forces and ensuring functional stability. The nano-silica anti-fouling layer 106d achieves self-cleaning through its superhydrophobic properties, reducing maintenance costs.
