[0023] Example
[0024] To address the limitation of existing conductive foams in complex electromagnetic environments or scenarios requiring high material versatility, reference was made to... Figure 1 As shown, this application discloses a high-performance magnetic conductive foam structure, including a foam body 10. A conductive cloth 30 is adhered to the outside of the foam body 10 by hot melt adhesive 20, and one side of the conductive cloth 30 is adhered to the other side of the conductive cloth 30 by hot melt adhesive 20. A flexible magnetic material 40 is provided on the side of the conductive cloth 30 that is in contact with the front and / or back of the foam body 10 and is in contact with the hot melt adhesive 20. Based on the combination of the foam body 10 and the conductive cloth 30 by hot melt adhesive 20, the functions of conducting electricity and absorbing waves of traditional conductive foam can be realized. In addition, in specific use, one or both sides of the conductive foam structure are attached to electronic components. In this way, the corresponding flexible magnetic material 40 can automatically attract the electronic components and thus achieve fixation. This structure has good flexibility and can be adjusted and installed according to changes in spatial environment and shape, and it is relatively stable in use.
[0025] refer to Figure 2 As shown, in another embodiment, the conductive cloth 30 of this application has a flexible magnetic material 40 that is bonded to the hot melt adhesive 20 on the side that is in contact with the front of the foam body 10, or the conductive cloth 30 has a flexible magnetic material 40 that is bonded to the hot melt adhesive 20 on the side that is in contact with the back of the foam body 10; the conductive cloth 30 has a conductive adhesive 50 on the outside of the side that is not covered with the flexible magnetic material 40. As an auxiliary material, release paper 60 is attached to the conductive adhesive 50. In some application scenarios, one side of the conductive foam structure can be attracted to electronic components through the flexible material, and the other side can be attracted to electronic components through the conductive adhesive 50. Of course, in actual use, the operator must tear off the release paper 60.
