Description

Technical Field

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

[0002] In the operation of electronic equipment and mechanical protection, foam components with both conductive and cushioning functions are often required to achieve electromagnetic shielding, electrostatic discharge, or circuit conduction, while also coping with vibration and compression conditions. Existing conductive foams mostly employ a composite structure of a single conductive layer and sponge. While this meets basic conductivity and cushioning requirements, it has significant drawbacks: Most products only have a common conductive layer on one side, which has poor wear resistance. During long-term use, the conductive layer is easily damaged by friction, thus losing its conductive function. Although some improved structures increase the thickness of the conductive layer, they ignore the stability of the interlayer connection and often use non-conductive adhesives to bond the layers, which can easily form conductive breaks and affect the overall conductivity continuity. Utility Model Content

[0003] To address the technical problems existing in the background art, this utility model proposes a foam structure made of wear-resistant and conductive material.

[0004] This utility model proposes a wear-resistant and conductive foam structure, which includes a first conductive cloth, a first acrylic adhesive, a conductive sponge, a second acrylic adhesive, and a second conductive cloth stacked sequentially from the inside out. A third acrylic adhesive is provided on the side of the second conductive cloth away from the conductive sponge, and a release paper is provided on the side of the third acrylic adhesive away from the second conductive cloth.

[0005] Furthermore, the first conductive cloth and the second conductive cloth are made of the same material, and both are wear-resistant materials.

[0006] Furthermore, the wear-resistant material is configured as conductive fibers.

[0007] Furthermore, the first, second, and third acrylic adhesives have the same thickness and all have both conductive and adhesive functions.

[0008] Furthermore, the conductive sponge is a conductive foam with elasticity and a compression recovery rate of not less than 80%.

[0009] Furthermore, the surface of the release paper is provided with an anti-stick coating, and the size of the release paper is adapted to the size of the third acrylic adhesive.

[0010] Furthermore, the thickness of both the first conductive cloth and the second conductive cloth is 0.1-0.3 mm, and the surface is flat and wrinkle-free.

[0011] The beneficial effects of this utility model are as follows: Through the multi-layer synergistic design of double-layer conductive fiber conductive cloth, three-layer conductive acrylic adhesive, high-resilience conductive sponge, and adaptable release paper, it can achieve stable conductivity and excellent wear resistance during long-term use by means of double-layer wear-resistant conductive cloth and continuous conductive adhesive channels, avoiding functional failure due to friction damage or conductive breakage. It can also adapt to deformation conditions such as vibration and compression by means of high-resilience conductive sponge, and can be quickly installed by directly pasting after peeling off the release paper. At the same time, it ensures that the adhesive is not contaminated during storage and transportation. Finally, it achieves integrated functions of wear resistance, conductivity, cushioning, and easy installation, effectively extending service life and expanding the applicable scenarios to meet the comprehensive performance requirements of high-precision electronic equipment, mechanical components, etc. Attached Figure Description

[0014] Reference Figure 1 This utility model proposes a wear-resistant and conductive foam structure. This structure comprises multiple functional components stacked sequentially from the inside out, forming a complete integrated wear-resistant and conductive structure. Each layer is tightly bonded, synergistically achieving conductive, wear-resistant, adhesive, and protective functions. The specific technical solution is as follows: The innermost layer is the first conductive cloth 1, which serves as the inner conductive and wear-resistant protective layer of the structure. Its material is conductive fiber, with a thickness controlled between 0.1-0.3mm. The surface is flat and wrinkle-free, which can ensure stable conductivity and resist wear when internal components come into contact with the outside. The outer side of the first conductive cloth 1 is bonded and fixed to the conductive sponge 3 by the first acrylic adhesive 2. The first acrylic adhesive 2 has both conductive and adhesive functions. While achieving interlayer fixation, it ensures the continuity of the conductive path. The conductive sponge 3 is the core elastic conductive component of the structure. It uses conductive foam with elasticity and a compression recovery rate of not less than 80%. It can quickly return to its original shape after being squeezed. It can adapt to the deformation requirements under different working conditions and maintain stable conductivity. The outer side of the conductive sponge 3 is connected to the second conductive cloth 5 by the second acrylic adhesive 4. The second acrylic adhesive 4 has the same specifications and thickness as the first acrylic adhesive 2 and also has the same conductive and adhesive functions, ensuring the firmness of the interlayer connection and the continuity of conductivity. The second conductive cloth 5 has the same material and thickness as the first conductive cloth 1. As the outer wear-resistant conductive layer of the structure, it forms a two-way protection with the first conductive cloth 1, further improving the wear resistance of the overall structure and strengthening the conductivity. The outer side of the second conductive cloth 5 is coated with a third acrylic adhesive 6. The thickness of the third acrylic adhesive 6 is the same as that of the first two layers of acrylic adhesive, maintaining the overall uniformity of the structure's thickness. Its main function is to achieve the bonding and fixing of the entire foam structure to the external components to be installed, while continuing the conductive path to ensure that good conductivity is maintained after installation. Release paper 7 is attached to the outer side of the third acrylic adhesive 6. The surface of the release paper 7 is provided with an anti-stick coating and its size is perfectly matched with the third acrylic adhesive 6. It can effectively protect the adhesive surface of the third acrylic adhesive 6 and prevent it from being contaminated or prematurely bonded during storage and transportation. When using it, you only need to peel off the release paper 7 to quickly stick the foam structure to the target position. Through the precise coordination of each layer of components, the entire foam structure achieves stable conductivity while enhancing wear resistance with the conductive cloth made of double-layer conductive fiber material. Conductive acrylic adhesive ensures interlayer connection and conductivity continuity, and high-resilience conductive sponge adapts to deformation requirements. Ultimately, it achieves wear resistance, conductivity, easy installation, and long service life, and can be widely used in electronic devices, mechanical components, and other scenarios that require both conductivity and wear resistance.

Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
