[0002] Electro-galvanizing is an advanced metal surface treatment process that uses electrolysis to evenly coat the surface of iron sheets with a layer of zinc, giving them excellent corrosion resistance and an attractive appearance. This process not only effectively extends the service life of iron sheets but also enhances their market value. During processing, carefully selected iron sheets undergo rigorous pretreatment to ensure a clean and impurity-free surface before entering the electro-galvanizing bath. Under precisely controlled current, voltage, and plating solution conditions, zinc ions are reduced and deposited on the iron sheet surface, forming a dense coating.

[0003] However, currently, hot-dip galvanized iron sheets in existing technologies are all individual pieces, which makes them inconvenient to splice, cannot guarantee the tightness and accuracy of the joints, and are inconvenient to use. In addition, the existing hot-dip galvanized iron sheets have poor structural strength and cannot meet the needs of users. Utility Model Content

[0023] refer to Figures 1 to 4 The high impact-resistant reinforced electro-galvanized iron sheet described in this embodiment includes a zinc-iron sheet body 1, a reinforcing rib 2 at the lower end of the zinc-iron sheet body 1, and a connecting mechanism 3 on the outer side of the zinc-iron sheet body 1.

[0024] The zinc-iron plate body 1 is composed of a base layer 101, a graphene-reinforced zinc-based composite coating 102, a polymer nano-coating 103, and a biodegradable polymer coating 104. The graphene-reinforced zinc-based composite coating 102 is disposed between the base layer 101 and the polymer nano-coating 103, and the polymer nano-coating 103 is disposed between the graphene-reinforced zinc-based composite coating 102 and the biodegradable polymer coating 104. Graphene and the zinc-based coating are combined through an electrochemical method to form a composite coating. The layered structure of graphene can effectively disperse impact force, and its high thermal conductivity helps to dissipate heat quickly, reducing the impact of thermal stress on the coating. Nanotechnology is used to uniformly disperse the polymer in the coating to form a nanoscale network structure. This structure can effectively absorb and disperse impact energy. Using biodegradable polymer materials as the coating matrix, it maintains excellent impact resistance while having good corrosion resistance and wear resistance, meeting the needs of various application scenarios.

[0025] The connecting mechanism 3 includes an expansion groove 301, which is located on the outside of the zinc-iron plate body 1. The groove opening of the expansion groove 301 is provided with a connecting sleeve 302. A connecting groove 304 is provided on the outside of the zinc-iron plate body 1. A mating block 305 is provided on the inner side of the connecting groove 304. A fixing bolt 303 is provided on the inner side of the zinc-iron plate body 1. A locking nut 306 is threadedly connected to the outer side of the fixing bolt 303. When two zinc-iron plate bodies 1 are spliced ​​together, the connecting sleeve 302 of one zinc-iron plate body 1 is inserted into the mating block 305 of the other zinc-iron plate body 1. During the insertion process, the connecting sleeve 302 enters the corresponding connecting groove 304. At the same time, one end of the mating block 305 passes through the connecting sleeve 302 and is inserted into the corresponding expansion groove 301. Then, the fixing bolt 303 is inserted from the top of the zinc-iron plate body 1 until it passes through, and then the locking nut 306 is used to lock it.

[0026] refer to Figure 1The reinforcing ribs 2 at the lower end of the zinc-iron plate body 1 are in the form of a grid, and the cross-section of the reinforcing ribs 2 is trapezoidal. By using grid-shaped reinforcing ribs 2, the impact resistance of the zinc-iron plate body 1 can be further improved.

[0027] refer to Figure 2 The connecting sleeve 302 is rectangular in shape. The inner wall of the connecting sleeve 302 is on the same plane as the inner wall of the expansion groove 301. Through the expansion groove 301 corresponding to the connecting sleeve 302, when the two zinc-iron plate bodies 1 are connected, the mating block 305 of one of them can be extended into the expansion groove 301 through the connecting sleeve 302 of the other, thereby ensuring the connection strength of the two zinc-iron plate bodies 1.

[0028] refer to Figure 2 and Figure 3 The inner side of the connecting sleeve 302 is provided with a first connecting hole 7, one end of which extends through the sleeve wall of the connecting sleeve 302. The inner side of the zinc-iron plate body 1 is provided with a second connecting hole 9, one end of which extends through the mating block 305. When the two zinc-iron plate bodies 1 are connected, the first connecting hole 7 and the second connecting hole 9 at the corresponding connection positions overlap, which facilitates the insertion of the fixing bolt 303.

[0029] refer to Figure 3 A positioning groove 8 is provided at the upper end of the second connecting hole 9. The end of the fixing bolt 303 is inserted into the positioning groove 8. The positioning groove 8 at the second connecting hole 9 can be used to conveniently position the end of the fixing bolt 303. After the fixing bolt 303 is inserted, the operator does not need to use other tools to position the fixing bolt 303. The locking nut 306 can be used directly to lock it, making the installation more convenient.

[0030] refer to Figure 3 A gasket 10 is provided between the zinc-iron plate body 1 and the locking nut 306. One end of the fixing bolt 303 moves through the center of the gasket 10. By setting the gasket 10, pressure can be distributed, surface defects can be compensated, and sealing or anti-loosening properties can be provided to ensure the long-term stability of the connection under load, vibration or environmental medium.

[0031] Operating principle and advantages: When splicing two zinc-iron plate bodies 1, the connecting sleeve 302 of one zinc-iron plate body 1 is inserted into the mating block 305 of the other zinc-iron plate body 1. During the insertion process, the connecting sleeve 302 enters the corresponding connecting groove 304, and at the same time, one end of the mating block 305 passes through the connecting sleeve 302 and is inserted into the corresponding expansion groove 301. Then, the fixing bolt 303 is inserted from the top of the zinc-iron plate body 1 until it passes through, and then the locking nut 306 is used to lock it.

[0032] During use, graphene is combined with a zinc-based coating through an electrochemical method to form a composite coating. The layered structure of graphene can effectively disperse impact force, while its high thermal conductivity helps to dissipate heat quickly and reduce the impact of thermal stress on the coating. Nanotechnology is used to uniformly disperse polymers in the coating to form a nanoscale network structure. This structure can effectively absorb and disperse impact energy. Biodegradable polymer materials are used as the coating matrix, which maintains excellent impact resistance while having good corrosion resistance and wear resistance, and can meet the needs of various application scenarios.
