Description

Technical Field

[0001] This utility model relates to the field of foam-related technology, and in particular to a conductive foam structure. Background Technology

[0002] Due to its excellent properties, conductive foam is widely used in various electronic products. Although existing conductive foams can meet the usage requirements, they still have certain structural shortcomings. For example, conductive foam is not waterproof, has poor compression resilience, weak tensile strength, and is prone to tearing, all of which affect its service life. Utility Model Content

[0003] In order to overcome the existing technical defects, the purpose of this utility model is to provide a conductive foam structure to solve the above-mentioned technical problems.

[0004] The technical solution adopted by this utility model to solve the technical problem is as follows:

[0005] According to one aspect of this utility model, a conductive foam structure is designed, comprising: a foam layer and an elastic support layer connected to the top of the foam layer by conductive adhesive. The elastic support layer comprises, from top to bottom, a waterproof layer, a conductive cloth layer, a first tensile layer, an aerogel particle layer, a second tensile layer, and a conductive layer connected together by conductive adhesive. The thickness of the aerogel particle layer is 0.03-0.15 mm.

[0006] By employing the above technical solution, the conductive foam utilizes the excellent resilience of aerogel to maintain good compressibility and elasticity even after prolonged use, thus extending its service life. By setting a reasonable thickness for the aerogel particle layer, the thickness of the conductive foam is kept relatively thin while ensuring compressibility and elasticity. The inclusion of a first and second tensile layer gives the conductive foam good tensile strength, making it less prone to tearing, further extending its service life. The addition of a waterproof layer provides a degree of water resistance, improving its waterproofing ability. Therefore, the conductive foam's performance in multiple aspects is improved, effectively enhancing its stability and extending its service life.

[0007] To better address the aforementioned technical deficiencies, this utility model also offers a superior technical solution:

[0008] In some embodiments, a wear-resistant layer is provided above the waterproof layer, the wear-resistant layer having a thickness of 0.01-0.025 mm. By providing the wear-resistant layer, the wear resistance of the conductive foam can be improved, further extending its service life.

[0009] In some embodiments, a flame-retardant layer is provided between the waterproof layer and the wear-resistant layer. The flame-retardant layer enhances the flame-retardant properties of the conductive foam, thereby improving safety during use.

[0010] In some embodiments, a carbon fiber layer is disposed between the second tensile layer and the conductive layer.

[0011] In some embodiments, the thickness of the aerogel particle layer is 0.08 mm.

[0012] In some embodiments, an aluminum foil shielding layer with a thickness of 0.012-0.018 mm is provided between the flame-retardant layer and the conductive fabric layer. The aluminum foil shielding layer can improve the electromagnetic shielding performance of the conductive foam.

[0013] In some embodiments, the conductive layer is a graphite conductive film or a graphene conductive film.

[0014] In some embodiments, both the first tensile layer and the second tensile layer are glass fiber woven meshes, and a polyester film layer is attached thereon. Attached Figure Description
