There are many types of coated steel wire, the most common of which include galvanized steel wire and magnesium alloy coated steel wire. By applying one or more layers of metal coating to the surface of the steel wire, its corrosion resistance can be significantly improved, thereby meeting the higher performance requirements of steel wire products in different fields. However, although these coated steel wires have a certain degree of corrosion resistance, their service life is relatively short.

Various aspects of this utility model are described in this disclosure with reference to the accompanying drawings, which illustrate numerous illustrative embodiments. The embodiments of this disclosure are not necessarily defined to include all aspects of this utility model. It should be understood that the various concepts and embodiments described above, as well as those described in more detail below, can be implemented in any of many ways, because the concepts and embodiments disclosed in this utility model are not limited to any particular implementation. Furthermore, some aspects of this utility model can be used alone or in any suitable combination with other aspects disclosed in this utility model.

[0018] Example 1

[0019] like Figure 1-3As shown, this is the first embodiment of the present invention. This embodiment provides a magnesium alloy coated steel wire with an alloy structural steel base, including an inorganic coating 1 and a steel base 2. A reinforcing core 3 is fixedly connected to the inner cavity of the steel base 2. The reinforcing core 3 is used to improve the strength of the steel base 2. A recessed area 5 is opened on the surface of the steel base 2. A magnesium alloy coating layer 4 is provided in the inner cavity of the recessed area 5. The surface of the magnesium alloy coating layer 4 is also coated with an isolation layer 6, a first anti-corrosion layer 7, and a second anti-corrosion layer 8. The isolation layer 6 is used to protect the magnesium alloy coating layer 4.

[0020] like Figure 1-3 As shown, the reinforcing core 3 fixed inside the steel substrate 2 enhances the strength of the steel substrate 2, making the steel wire more stable under external force and reducing coating damage caused by deformation. A recessed area 5 is formed on the surface of the steel substrate 2, and a magnesium alloy coating layer 4 is installed inside the recessed area 5, covering part of the surface of the steel substrate 2 and forming a smooth and flat surface together with the steel substrate 2. This not only increases the contact area between the coating and the substrate, improving adhesion, but the design of the recessed area 5 also helps to slow down the direct erosion of the substrate by corrosive media. An isolation layer 6 is coated on the surface of the magnesium alloy coating layer 4. Used to protect the magnesium alloy coating layer 4, the isolation layer 6 can effectively isolate the external environment from the corrosion of the magnesium alloy coating layer 4 and reduce the formation of magnesium oxide. The isolation layer 6 is coated with a first anti-corrosion layer 7 and a second anti-corrosion layer 8 in sequence, which further enhances the anti-corrosion performance of the steel wire. The first anti-corrosion layer 7 has good anti-corrosion performance and mechanical strength, which can further enhance the anti-corrosion ability of the steel wire. The second anti-corrosion layer 8 has excellent hydrophobic properties, which can further prevent moisture and corrosive media from corroding the steel wire. The outermost layer is an inorganic coating 1, which not only provides additional protection, but may also have aesthetic and marking functions.

[0021] Example 2

[0022] Reference Figure 1-3 This is the second embodiment of the present invention, which is based on the previous embodiment.

[0023] In this embodiment, the isolation layer 6 is coated on the surface of the magnesium alloy coating layer 4, and the inner cavity of the recess 5 forms a smooth and flat surface with the surface of the steel substrate 2 through the magnesium alloy coating layer 4.

[0024] The first anti-corrosion layer 7 is coated on the surface of the isolation layer 6, the second anti-corrosion layer 8 is coated on the surface of the first anti-corrosion layer 7, and the inorganic coating 1 is located on the surface of the second anti-corrosion layer 8.

[0025] The isolation layer 6 is coated with fluorocarbon paint, the first anti-corrosion layer 7 is made of epoxy glass flake material, and the second anti-corrosion layer 8 is made of NC550 nano hydrophobic material.

[0026] The steel substrate 2 adopts a 35CrMo alloy structure, and the inorganic coating 1 adopts inorganic pigments.

[0027] like Figure 1-3 As shown, the steel substrate 2 adopts a 35CrMo alloy structure, which is suitable for occasions that need to withstand large stress and complex environments. The isolation layer 6 adopts a fluorocarbon paint coating, which has excellent weather resistance and corrosion resistance, and can effectively isolate the external environment from the erosion of the magnesium alloy coating layer 4. The first anti-corrosion layer 7 adopts epoxy glass flake material, which has good anti-corrosion performance and mechanical strength, and can further enhance the anti-corrosion ability of the steel wire. The second anti-corrosion layer 8 adopts NC550 nano hydrophobic material, which has excellent hydrophobic properties and can prevent moisture and corrosive media from further eroding the steel wire. The inorganic coating 1, as the outermost layer, not only provides additional protection, but may also give the steel wire a specific color and aesthetics through the selection of inorganic pigments. Through multi-layer protection and anti-corrosion design, combined with high-strength alloy steel substrate and coating materials, the characteristics of high strength, corrosion resistance and long service life are achieved.

[0028] In use, the steel substrate 2, as the main structure of the steel wire, bears the main load. Employing a 35CrMo alloy structure, it possesses high strength and toughness. The reinforcing core 3 enhances the strength of the steel substrate 2, further increasing the load-bearing capacity of the steel wire. A recess 5 is formed on the surface of the steel substrate 2 to accommodate the magnesium alloy coating layer 4. The magnesium alloy coating layer 4 fills the recess 5, forming a smooth and flat surface with the steel substrate 2, improving the surface smoothness and corrosion resistance of the steel wire. The isolation layer 6 uses a fluorocarbon paint coating to protect the magnesium alloy coating layer 4 from external environmental corrosion. The fluorocarbon paint coating has excellent weather resistance and corrosion resistance, effectively extending the service life of the magnesium alloy coating layer 4. The first anti-corrosion layer 7 uses epoxy glass flake material to further enhance the anti-corrosion capability of the steel wire. Epoxy glass flake material has good anti-corrosion performance and mechanical strength, forming a dense anti-corrosion layer that prevents corrosive media from eroding the steel wire. The second anti-corrosion layer 8 uses NC550 nano-hydrophobic material to provide additional anti-corrosion protection and increase the hydrophobicity of the steel wire. The NC550 nano-hydrophobic material can form a nano-scale hydrophobic layer to prevent further erosion of the steel wire by moisture and corrosive media. The inorganic coating 1 uses inorganic pigments as the outermost layer to provide additional protection and aesthetics. The inorganic coating 1 has good weather resistance and chemical stability, and can resist the erosion of the external environment. At the same time, it gives the steel wire a specific color and texture. The layers interact with each other to form a composite material with excellent performance. The reinforcing core 3 improves the strength of the steel wire. The magnesium alloy coating layer 4, the isolation layer 6, the first anti-corrosion layer 7 and the second anti-corrosion layer 8 together enhance the corrosion resistance of the steel wire, while the inorganic coating 1 provides additional protection and aesthetics. Through the multi-layer structure design, the strength, corrosion resistance, wear resistance and aesthetics of the particulate magnesium alloy coated steel wire are effectively improved, making it suitable for a variety of complex environments and applications.
