Description

Technical Field

[0001] The utility model relates to the membrane field, in particular to an anti-rust membrane structure. Background Art

[0002] Traditionally, in order to prevent metal products from rusting, a layer of grease is applied to all places on the metal products that may come into contact with the air to block oxygen and water from coming into contact with the metal products. In addition, some people absorb grease on paper and use the grease-absorbed paper to package metal products. However, traditional metal product packaging methods have the following disadvantages: 1. Packaging is time-consuming and costly; 2. Grease will deteriorate after being stored for a long time; 3. Unpacking is time-consuming and requires high manpower; 4. The large amount of grease used seriously causes environmental pollution and is not environmentally friendly. Therefore, a vacuum packaging method has emerged, which can completely block the contact between oxygen and water in the air and metal products; but its cost is too high, and after the metal products have been stored for a long time, their packaging materials will deteriorate, and oxygen and water in the air will also penetrate into the packaging, causing the metal products to rust.

[0003] The existing aluminum foil anti-rust film cannot meet the needs of users in actual use, and has a complex structure and high cost, which leads to increased production costs.

[0004] The patent with announcement number: CN206426592U proposes an improved aluminum foil anti-rust film structure, in which a carbon fiber mesh is arranged between the middle structural layer and the inner structural layer. This can not only enhance the structural strength of the anti-rust film, but also meet the quality requirements of lightweight anti-rust film, and the carbon fiber mesh also has conductive properties.

[0005] However, the anti-rust film of this type of structure does not have an anti-corrosion effect. When in use, its service life may be short. In addition, during use, the anti-rust film may rupture due to insufficient toughness, which will affect the use effect of the anti-rust film and reduce the anti-rust strength of this type of anti-rust film. Utility Model Content

[0006] Based on this, the purpose of the utility model is to provide an anti-rust film structure to solve the technical problem that the anti-rust film of this type of structure does not have an anti-corrosion effect, which may result in a short service life when used, and during use, the anti-rust film may be broken due to insufficient toughness of the anti-rust film, thereby affecting the use effect of the anti-rust film and reducing the anti-rust strength of this type of anti-rust film.

[0007] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: an anti-rust membrane structure, including an aluminum membrane structure, an anti-corrosion layer is arranged on the top of the aluminum membrane structure, and a composite membrane is fixedly connected to the top of the anti-corrosion layer, an anti-rust inner layer is arranged on the bottom of the aluminum membrane structure, a carbon fiber mesh is fixedly connected between the composite membrane, the anti-corrosion layer, the aluminum membrane structure and the anti-rust inner layer, the anti-corrosion layer is made of type III polypropylene material, and the anti-rust inner layer is made of polyethylene PE masterbatch.

[0008] By adopting the above technical scheme, the anti-corrosion layer made of type III polypropylene material can improve the anti-corrosion performance of the anti-rust film of this structure, extend its service life, and thus improve the anti-rust strength of such anti-rust film. This can not only enhance the structural strength of the anti-rust film, but also meet the quality requirements of lightweight anti-rust film. The carbon fiber mesh also has conductive properties.

[0009] The utility model is further configured that the composite film, the anti-corrosion layer, the aluminum film structure and the anti-rust inner layer are all combined into an integrated structure by an adhesive, and the adhesive is glue.

[0010] By adopting the above technical solution, the composite film, the anti-corrosion layer, the aluminum film structure and the anti-rust inner layer can be better connected and fixed, and the production cost is not high, which is conducive to production.

[0011] In summary, the utility model mainly has the following beneficial effects:

[0012] 1. The utility model can improve the anti-corrosion performance of the anti-rust film of this structure by using the anti-corrosion layer made of three types of polypropylene materials, prolong its service life, and thus improve the anti-rust strength of such anti-rust film;

[0013] 2. The utility model has a carbon fiber mesh fixedly connected between the composite film, the anti-corrosion layer, the aluminum film structure and the anti-rust inner layer, so that the structural strength of the anti-rust film can be enhanced and the quality requirement of lightweight anti-rust film can be met. The carbon fiber mesh also has conductive properties. BRIEF DESCRIPTION OF THE DRAWINGS
