[0025] The present invention will be described in further detail below with reference to the accompanying drawings.

[0026] Combined with attachment Figure 1 To the attached Figure 5 A corrosion-resistant aluminum profile comprises a profile body 1, wherein the upper and lower ends of the profile body 1 are integrally formed with connecting parts, and the left and right outer sides of the profile body 1 are fixed with a bonding reinforcement layer 2, wherein the bonding reinforcement layer 2 is a chromate conversion film layer with a thickness of 0.5 microns to 1 micron, and a barrier protective layer 3 is fixed to the outside of the bonding reinforcement layer 2, wherein the barrier protective layer 3 is an epoxy resin coating with a thickness of 50 microns to 100 microns, and a strong corrosion-resistant layer 4 is fixed to the outside of the barrier protective layer 3, wherein the strong corrosion-resistant layer 4 is a polytetrafluoroethylene coating with a thickness of 20 microns to 50 microns, and a strengthening support layer 5 is fixed to the inside of the profile body 1, wherein the strengthening support layer 5 is a carbon fiber reinforced composite material layer with a thickness of 1 mm to 2 mm, and a stress buffer layer 6 is fixed to the inside of the strengthening support layer 5, wherein the stress buffer layer 6 is a rubber elastic material layer with a thickness of 0.5 mm to 1 mm.

[0027] The working principle of the highly corrosion-resistant aluminum profile of the utility model is as follows: when the aluminum profile is in a corrosive environment, the outermost strong corrosion-resistant layer plays a role first, and the polytetrafluoroethylene coating blocks the erosion of most corrosive media with its extremely low surface energy and excellent corrosion resistance and weather resistance. If a small amount of corrosive substances breaks through this layer, the epoxy resin coating of the barrier protective layer will further block it and prevent it from contacting the profile body. The bonding reinforcement layer ensures the tightness of the bonding between the layers, and also provides preliminary corrosion protection for the entire protection system. Inside the profile body, the carbon fiber reinforced composite material of the strengthening support layer provides high strength and high rigidity support for the aluminum profile, ensuring that it is not easily deformed when subjected to external forces. The rubber elastic material of the stress buffer layer can absorb and relieve the stress to which the aluminum profile is subjected during use, and prevent fatigue damage caused by stress concentration.

[0028] Bond Enhancement Layer 2 (Chromate Conversion Coating): This layer forms a dense protective film on the profile surface, strengthening the bond with the barrier layer and preliminarily improving the corrosion resistance of the aluminum profile. Through chemical treatment, the profile is immersed in a solution containing chromate. Under certain temperature and time conditions, the chromate reacts with the aluminum profile surface to form a chromate conversion coating.

[0029] Barrier Protective Layer 3 (Epoxy Coating): This layer offers excellent chemical and water resistance and strong adhesion, effectively preventing external corrosive substances from contacting the profile, further enhancing the aluminum profile's corrosion resistance. The epoxy coating is evenly applied to the bonding reinforcement layer by spraying or dipping, then cured at a specific temperature to form a 50 to 100 micron thick epoxy coating.

[0030] Strong Anti-Corrosion Layer 4 (PTFE Coating): With extremely low surface energy and excellent corrosion and weather resistance, it provides the outermost layer of strong protection for the aluminum profile, preventing erosion by various corrosive media. The PTFE coating is evenly applied to the barrier layer by spraying or electrostatic spraying, forming a PTFE coating with a thickness of 20 to 50 microns.

[0031] Strengthening support layer 5 (carbon fiber reinforced composite material layer): This layer offers high strength and rigidity, enhancing the overall strength and stability of the aluminum profile. First, carbon fibers are mixed with materials such as resin to create a carbon fiber reinforced composite prepreg. This prepreg is then tightly bonded to the profile body through processes such as winding and molding, forming a strengthening support layer with a thickness of 1 to 2 mm.

[0032] Stress buffer layer 6 (rubber elastic material layer): This absorbs and relieves stress experienced by the aluminum profile during use, improving its fatigue resistance. The rubber elastic material is processed through extrusion, injection molding, or other methods into a layered structure that matches the internal shape of the profile. This layer is then embedded and fixed within the profile, forming a stress buffer layer with a thickness of 0.5 to 1 mm.

[0033] The above description of the present invention and its embodiments is non-limiting. The drawings show only one embodiment of the present invention, and the actual structure is not limited thereto. In short, if a person skilled in the art is inspired by the above, and does not deviate from the purpose of the present invention, without inventive design, a structure and embodiment similar to the technical solution should fall within the scope of protection of the present invention.
