[0017] Referring to Figures 1 to 4 The utility model provides a kind of composite corrosion-resistant rust-proof film, comprising: base film layer 1, the upper surface of the base film layer 1 is fixedly connected with composite layer 2, and the upper surface of composite layer 2 is fixedly connected with reinforcing layer 3, the upper surface of reinforcing layer 3 is fixedly connected with corrosion-resistant layer 4, and composite layer 2 is composed of oxygen-absorbing layer 6, rust-proof layer 7 and barrier layer 8, while the inner side of rust-proof layer 7 is fixedly connected with oxygen-absorbing layer 6, and the outer side of rust-proof layer 7 is fixedly connected with barrier layer 8.

[0018] ​In this embodiment, the uniformly formed through holes 5 on the surface of the base film layer 1 further enhances the air permeability of the base film layer 1, thereby helping to enhance the oxygen consumption effect of the oxygen-absorbing layer 6 on the cavity formed by the anti-rust film covering the object, thus reducing the oxygen content in the cavity covered by the anti-rust layer 7 and reducing the probability of corrosion of the covered object due to oxygen. The anti-rust layer 7 releases VCI anti-rust particles to the surface of the object, thereby further enhancing the anti-rust effect of the covered object. The barrier layer 8 effectively reduces the probability of external gas penetration, preventing the oxygen content in the cavity covered by the anti-rust layer 7 from increasing. The conductive adhesive used in the composite layer 2 and the conductive medium mixed in the reinforcing layer 3 effectively enhance the anti-static effect of the anti-rust film. The mesh-like reinforcing layer 3 also effectively enhances the overall structural strength of the anti-rust layer 7, reducing the probability of the anti-rust layer 7 being accidentally torn during use. At the same time, the corrosion-resistant layer 4 further enhances the corrosion resistance and wear resistance of the outer surface of the anti-rust film, further reducing the probability of accidental damage to the outer surface of the anti-rust film.

[0019] In a preferred embodiment, the base film layer 1 is made of polyethylene, and multiple sets of through holes 5 are uniformly opened on the surface of the base film layer 1, and the through holes 5 have a cylindrical structure.

[0020] In this embodiment, as Figure 1 and Figure 3 The uniformly distributed through holes 5 on the surface of the base film layer 1 can effectively enhance the air permeability of the base film layer 1, thereby helping to enhance the effect of the oxygen absorption layer 6 on the absorption and consumption of the encapsulated oxygen.

[0021] In a preferred embodiment, the reinforcing layer 3 has an overall mesh structure, and the reinforcing layer 3 is woven from polycarbonate fibers, with a conductive medium uniformly added inside the polycarbonate fibers.

[0022] In this embodiment, as Figure 1 and Figure 2 The mesh structure of the reinforcing layer 3 can help enhance the overall structural strength of the anti-rust layer 7 and reduce the chance of the anti-rust layer 7 being accidentally torn. The uniformly added conductive medium gives the anti-rust film a good anti-static effect.

[0023] As a preferred embodiment, the corrosion-resistant layer 4 is made of polytetrafluoroethylene, and the lower surface of the corrosion-resistant layer 4 is simultaneously fixedly connected to the upper surface of the reinforcing layer 3 and the composite layer 2, and the threads of the reinforcing layer 3 will be extruded into corresponding grooves on the surfaces of the corrosion-resistant layer 4 and the composite layer 2.

[0024] In this embodiment, as Figure 1 and Figure 2 During the process of bonding and fixing the corrosion-resistant layer 4 and the barrier layer 8, the reinforcing layer 3 set between the two will help enhance the stability of the fixed connection.

[0025] In a preferred embodiment, the oxygen-absorbing layer 6 is made of polyester film, and easily oxidizable substances are uniformly added to the polyester film, and the lower surface of the oxygen-absorbing layer 6 is fixedly connected to the upper surface of the base film layer 1.

[0026] In this embodiment, as Figure 4 The oxygen-absorbing layer 6 allows the anti-rust film to absorb and consume oxygen from the surrounding air after wrapping the item, thereby reducing the chance of the wrapped item being corroded by oxygen.

[0027] As a preferred embodiment, the barrier layer 8 is made of polyamide, and the upper surface of the barrier layer 8 is simultaneously fixedly connected to the reinforcing layer 3 and the corrosion-resistant layer 4.

[0028] In this embodiment, as Figure 4 The barrier layer 8 effectively reduces the chance of external gas penetrating into the inner cavity of the rust-proof film, thereby helping to reduce the wear rate of the oxygen-absorbing layer 6 and thus extending the protection time of the rust-proof film for the wrapped items.

[0029] In a preferred embodiment, the rust-preventive layer 7 is located between the barrier layer 8 and the oxygen-absorbing layer 6, and the barrier layer 8 and the oxygen-absorbing layer 6 are bonded and fixed on both sides of the rust-preventive layer 7 with conductive adhesive.

[0030] In this embodiment, as Figure 4 The rust-proof layer 7 helps to enhance the rust-proof effect of the wrapped item, and the conductive adhesive helps to enhance the anti-static effect of the inner side of the rust-proof film.

[0031] The composite corrosion-resistant and rust-proof film of this utility model, through the combination of corrosion-resistant layer 4, reinforcing layer 3 and composite layer 2, enables the rust-proof film to have good corrosion resistance and tear resistance, and can effectively consume oxygen in the encapsulated gas, thereby enhancing the protective effect of the rust-proof film on the item. Moreover, the setting of barrier layer 8 can help extend the service time of oxygen-absorbing layer 6 and reduce the oxygen content around the encapsulated item.
