Description

Technical Field

[0001] This utility model relates to the field of conductive foam technology, and in particular to a multi-layer wear-resistant conductive foam. Background Technology

[0002] Conductive foam refers to conductive cloth wrapped around flame-retardant sponge and treated to achieve good surface conductivity. It can be easily fixed to devices requiring shielding using adhesive tape. Various cross-sectional shapes, installation methods, UL ratings, and shielding effectiveness are available. As a new type of antistatic material, conductive foam is widely used in electronic products such as PDP TVs, LCD monitors, LCD TVs, mobile phones, laptops, and MP3 players for electromagnetic shielding and electrostatic protection. However, existing conductive foams exhibit poor abrasion resistance during use, resulting in a short service life. Utility Model Content

[0003] The purpose of this invention is to at least solve one of the aforementioned technical defects.

[0004] Therefore, one objective of this utility model is to provide a multilayer wear-resistant conductive foam to solve the problems mentioned in the background art and overcome the shortcomings of the existing technology.

[0005] To achieve the above objectives, one embodiment of this utility model provides a multilayer wear-resistant conductive foam, comprising a release layer, a conductive adhesive layer disposed on the upper surface of the release layer, a first conductive cloth layer disposed on the upper surface of the conductive adhesive layer, a first foam layer disposed on the upper surface of the first conductive cloth layer, a metal fiber layer disposed on the upper surface of the first foam layer, a second foam layer disposed on the upper surface of the metal fiber layer, a second conductive cloth layer disposed on the upper surface of the second foam layer, a fireproof interlayer disposed on the upper surface of the second conductive cloth layer, a first wear-resistant layer disposed on the upper surface of the fireproof interlayer, and a first friction protrusion fixedly connected to the top of the first wear-resistant layer. The upper surface of the material is provided with a second wear-resistant layer, and a second friction protrusion is fixedly connected to the upper surface of the second wear-resistant layer. The first friction protrusion and the second friction protrusion are staggered. Both the first wear-resistant layer and the second wear-resistant layer are provided with wear-resistant support structures. The technical effect achieved by the above solution is that, through the cooperation between the release layer, conductive adhesive layer, first conductive cloth layer, first foam layer, metal fiber layer, second conductive foam layer, second conductive cloth layer, fireproof interlayer, first wear-resistant layer, first friction protrusion, second wear-resistant layer, second friction protrusion and wear-resistant support structure, the wear resistance of the conductive foam can be greatly improved through multiple wear-resistant layers, and the service life of the conductive foam can be greatly improved.

[0006] Preferably, in any of the above solutions, the bottom of the second wear-resistant layer is fixedly connected to an adhesive part, the surface of the adhesive part being tangent to the surface of the first friction protrusion. The number of the first friction protrusion, the second friction protrusion, and the adhesive part are all several, and the several first friction protrusions, second friction protrusions, and adhesive parts are equidistantly distributed. The technical effect achieved by the above solution is that the adhesive part enables the first wear-resistant layer and the second wear-resistant layer to be more tightly bonded, thereby reducing the deformation of the second friction protrusion.

A second rod and a third rod are fixedly connected to the top of the first rod. The second rod and the third rod are staggered. One end of the first rod is inserted into the interior of the second friction protrusion, and one end of the third rod is inserted into the interior of the first friction protrusion. The technical effect achieved by the above embodiment is that the first rod, the second rod, and the third rod can support the first friction protrusion and the second friction protrusion, thereby reducing the deformation that occurs when the first friction protrusion and the second friction protrusion rub against each other.

[0008] Preferably, in any of the above schemes, the height of the second rod is greater than the height of the third rod, and there are several second and third rods. These several second and third rods are equidistantly distributed on the surface of the first rod. The technical effect achieved by adopting the above scheme is that the first, second, and third rods can support the first and second friction protrusions, thereby reducing the deformation that occurs when the first and second friction protrusions rub against each other.

[0009] Preferably, in any of the above solutions, the surface of the second wear-resistant layer is provided with a plurality of through holes, and one end of the first friction protrusion penetrates through the through holes. The technical effect achieved by the above solution is that, by having the first friction protrusion pass through the through holes, the friction surface of the second friction protrusion can be reduced when the second friction protrusion is worn to a certain extent, thereby slowing down the wear of the second friction protrusion.

[0010] Preferably, the surfaces of the first wear-resistant layer, the first friction protrusion, the second wear-resistant layer, and the second friction protrusion are all coated with wear-resistant paint, and the first wear-resistant layer and the second wear-resistant layer are bonded and fixed together. The technical effect achieved by adopting the above solution is that the wear resistance of the conductive foam can be further improved by the wear-resistant paint.

[0011] Preferably, the first wear-resistant layer is made of nylon, the second wear-resistant layer and the second friction protrusion are made of non-woven fabric, and the wear-resistant support structure is made of rubber. The technical effect achieved by adopting the above solutions is that the first wear-resistant layer and the second wear-resistant layer can greatly improve the wear resistance of the conductive foam and greatly improve the service life of the conductive foam through multiple wear-resistant layers.
