[0025] The technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0026] Refer to Figures 1-3 , an embodiment provided by the present utility model: a high-hardness waterproof and corrosion-resistant nano-coating structure, including a hard layer 1. The material used for the hard layer 1 is titanium nitride, which can increase the surface hardness, improve the wear resistance and scratch resistance, and make the coating more durable. The top end of the outer wall of the hard layer 1 is fixedly connected with an anti-corrosion layer 2. The material used for the anti-corrosion layer 2 is a zinc-nickel alloy coating, which can protect the substrate from the erosion of chemical substances and moisture. The top end of the outer wall of the anti-corrosion layer 2 is fixedly connected with a hydrophobic layer 3. The material used for the hydrophobic layer 3 is tetrafluoroethylene. This material not only makes the liquid form water droplets on the surface, but also can greatly reduce the residual water droplets. This coating has high innovation in the fields of anti-fouling and self-cleaning. The top end of the outer wall of the hydrophobic layer 3 is fixedly connected with a high-temperature resistant layer 4. The material used for the high-temperature resistant layer 4 is, and the silicon carbide coating has excellent high-temperature resistance and oxidation resistance, suitable for applications in high-temperature environments. The top end of the outer wall of the high-temperature resistant layer 4 is fixedly connected with a photocatalytic layer 5, which uses light energy to catalyze the decomposition of harmful substances to keep the surface clean and anti-fouling ability. The top end of the outer wall of the photocatalytic layer 5 is fixedly connected with an oleophobic layer 6. By setting the oleophobic layer 6, it can prevent grease and oil pollutants from adhering to the surface, suitable for application occasions that need to resist oil stains, and the material used for the oleophobic layer 6 is a silane compound. A strengthening component is provided at the top end of the hard layer 1.

[0027] Refer to Figures 2-3 , the strengthening component includes a positioning column 7. Positioning holes are formed on the surface of the anti-corrosion layer 2. The positioning column 7 penetrates and is slidably connected to the inner wall of the positioning hole of the anti-corrosion layer 2. Positioning holes are formed on the surface of the hydrophobic layer 3. The positioning column 7 penetrates and is slidably connected to the inner wall of the positioning hole of the hydrophobic layer 3. Positioning holes are formed on the surface of the high-temperature resistant layer 4. The positioning column 7 penetrates and is slidably connected to the inner wall of the positioning hole of the high-temperature resistant layer 4. By arranging the positioning column 7 on the surface of the hard layer 1 to penetrate the anti-corrosion layer 2, the hydrophobic layer 3 and the high-temperature resistant layer 4, a certain support can be provided by the columnar structure, enhancing the stability between materials. And the material used for the positioning column 7 is carbon nanotube, which has high strength, high toughness and good electrical conductivity. Due to its unique tubular structure and excellent properties, it can be used to construct columnar structures to enhance the mechanical properties and electrical conductivity of the coating. Multiple groups of positioning columns 7 are provided. Multiple groups of positioning columns 7 are fixedly connected to the top end of the outer wall of the hard layer 1. The top end of the outer wall of the positioning column 7 is fixedly connected to the bottom end of the outer wall of the high-temperature resistant layer 4.

[0028] Working principle: In practical applications, this nano-coating structure first functions through the hard layer 1 at the bottommost layer. The hard layer 1 is made of titanium nitride, and its high hardness significantly increases the hardness of the coating surface, effectively improving the wear resistance and scratch resistance. This enables the coating to maintain good integrity and durability when facing external forces such as friction and scratching. The anti-corrosion layer 2 above the hard layer 1 is composed of a zinc-nickel alloy coating, which can form an effective protective barrier to prevent chemicals and moisture from eroding the substrate, thereby protecting the internal structure from corrosion damage and extending the service life of the coating and the substrate. The hydrophobic layer 3 uses tetrafluoroethylene material, and its unique molecular structure causes liquids to form water droplets on the surface and roll off quickly, greatly reducing the remaining water droplets. It performs excellently in anti-fouling and self-cleaning, effectively preventing the accumulation of moisture and pollutants. The silicon carbide coating of the high-temperature resistant layer 4 ensures that the coating can still maintain stable performance in high-temperature environments due to its excellent high-temperature resistance and oxidation resistance, and is suitable for various high-temperature working conditions. The photocatalytic layer 5 can utilize light energy to catalytically decompose harmful substances, maintain the cleanliness and anti-fouling ability of the coating surface, and further enhance the self-cleaning and protection effects of the coating. The oleophobic layer 6 uses silane compounds to effectively prevent the attachment of grease and oil pollutants, making it play an important role in occasions where oil pollution needs to be resisted.

[0029] In terms of strengthening the coating structure, multiple positioning columns 7 composed of carbon nanotubes play a key role. These positioning columns 7 penetrate upward from the surface of the hard layer 1 through the anti-corrosion layer 2, the hydrophobic layer 3, and the high-temperature resistant layer 4. Their high strength and high toughness provide strong support between the layers, enhancing the stability between the coating materials. At the same time, the good electrical conductivity of carbon nanotubes may also help improve the electrical conductivity of the coating, enabling it to have more excellent comprehensive performance in specific applications.

[0030] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements for some of the technical features.
