Description

Technical Field

[0001] This utility model relates to the field of isolation and shielding, specifically a high-performance conductive foam. Background Technology

[0002] Conductive foam is a special type of foam material that is conductive. It is typically composed of conductive fillers and a foam matrix. This material combines the lightweight, softness, and shock-absorbing properties of foam with the electrical conductivity of conductive materials. Conductive foam can be used in electronic devices to reduce electromagnetic interference. It can be filled into gaps in the device housing to form a seal, preventing electromagnetic waves from entering or leaving. These properties of conductive foam make it an ideal choice for electronics, aerospace, defense, and other industries that require control of electromagnetic interference and to ensure good electrical contact.

[0003] However, traditional conductive foam is prone to cracking or peeling of the conductive layer after long-term compression or repeated deformation, resulting in an increase in resistivity. To address this issue, we propose a high-performance conductive foam. Utility Model Content

[0004] The purpose of this invention is to provide a high-performance conductive foam to solve the problems mentioned in the background section and overcome its technical defects.

[0005] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is: a high-performance conductive foam, including a foam body, an elastic conductive intermediate layer connected to the outer surface of the foam body, the elastic conductive intermediate layer being a composite material of carbon nanotubes and graphene, a metal plating layer connected to the outer surface of the elastic conductive intermediate layer, the metal plating layer being made of silver-copper alloy, and a conductive polymer fiber layer connected to the outer surface of the metal plating layer.

[0006] As a further improvement of this utility model: a waterproof layer is connected to the outer surface of the foam body, and the waterproof layer is made of polyurethane.

[0007] As a further improvement of this utility model: a connecting piece is connected to the back of the foam body, and an adhesive block is connected to the back of the connecting piece.

[0008] As a further improvement of this utility model: a connecting groove is provided on the upper surface of the foam body, and an adhesive sheet is connected to the inner wall of the connecting groove.

[0009] As a further improvement of this utility model, a connecting block is bonded to the side of the adhesive sheet away from the connecting groove.

[0010] Compared with existing technologies, the beneficial effects of this invention include: Firstly, by replacing the traditional conductive carbon coating layer with a combination of an elastic conductive intermediate layer, a metal plating layer, and a conductive polymer fiber layer, the conductive layer is prevented from cracking or peeling off, which would lead to an increase in resistivity. Furthermore, the conductive polymer fiber layer improves the flexibility and elasticity of the foam. Polymer fibers have excellent flexibility, allowing them to adapt to different shapes and pressures, enabling the foam to maintain good deformation recovery when subjected to external forces, further preventing cracking and peeling. In summary, this high-performance conductive foam, by using polymer fibers and optimizing their flexibility, not only improves its durability and reliability but also brings benefits in installation, maintenance, and user experience, giving it significant advantages in various application scenarios.

Therefore, the following detailed embodiments and accompanying drawings are merely illustrative descriptions of the technical solution of this utility model and should not be considered as the entirety of this utility model or as limitations or restrictions on the technical solution of this utility model.

[0018] An embodiment of the present invention is shown in conjunction with the accompanying drawings.

[0019] A high-performance conductive foam includes a foam body 1, with an elastic conductive intermediate layer 7 connected to the outer surface of the foam body 1. The elastic conductive intermediate layer 7 is a composite material of carbon nanotubes and graphene. Both carbon nanotubes and graphene are excellent conductive materials. Combining them into a composite material as a conductive intermediate layer can provide extremely high conductivity, which is beneficial for applications requiring conductivity, such as electromagnetic shielding and heating elements. A metal plating layer 8 is connected to the outer surface of the elastic conductive intermediate layer 7. Silver and copper are both very good conductive materials. Silver has the highest conductivity among all metals, while copper also has excellent conductivity and is relatively inexpensive. A silver-copper alloy is also available. Combining the advantages of both, it provides extremely high conductivity, which helps it perform well in applications requiring high conductivity. In addition, the foam body 1 and the elastic conductive intermediate layer 7 already provide good elasticity, and the silver-copper alloy plating layer 8 can also maintain this elasticity to a certain extent, while increasing the overall mechanical strength and durability. The metal plating layer 8 is made of silver-copper alloy, and the outer surface of the metal plating layer 8 is connected to a conductive polymer fiber layer 9. The conductive polymer fiber layer 9 can improve the flexibility and elasticity of the foam. The polymer fiber has good flexibility and can adapt to different shapes and pressures, so that the foam can maintain good deformation recovery ability when subjected to external forces.

[0020] In this embodiment, a waterproof layer 6 is connected to the outer surface of the foam body 1. The waterproof layer 6 is made of polyurethane, which is an effective waterproof material that can prevent water from penetrating into the foam body 1, thereby protecting the internal conductive structure from the influence of water and avoiding danger and damage to the equipment.

[0021] In this embodiment, a connecting piece 2 is connected to the back of the foam body 1, and an adhesive block 4 is connected to the back of the connecting piece 2. The adhesive block 4 on the back of the connecting piece 2 can be used to adhere and fix the required position, so that it can be tightly pasted and will not fall off, thus providing good durability for the whole.

[0022] In this embodiment, a connecting groove is provided on the upper surface of the foam body 1, and an adhesive piece 5 is connected to the inner wall of the connecting groove. Multiple splicing can be achieved through the adhesive piece 5 inside the connecting groove, thereby ensuring that even when facing a large application area, no gaps will occur during the pasting process, thus preventing moisture from entering the circuit components through the gaps.

[0023] In this embodiment, the side of the adhesive sheet 5 away from the connecting groove is bonded with the connecting block 3. The design of the connecting block 3 allows the foam body 1 to be easily spliced ​​into multiple parts to form a larger size or a specific shape of foam component. This is very advantageous for application scenarios that require large area coverage or specific shape. The use of the connecting block 3 allows the foam body 1 to be spliced ​​into multiple parts. The use of the connecting block 3 allows the size and shape of the foam component to be adjusted according to actual needs, increasing the design flexibility. Foam components of different sizes and shapes can be flexibly spliced ​​according to different application scenarios.

[0024] Working principle: First, workers use the adhesive tabs 5 inside the connecting groove to splice the connecting blocks 3, forming larger or specifically shaped foam components. This is highly advantageous for applications requiring large-area coverage or specific shapes. Furthermore, the size and shape can be adjusted according to actual needs, increasing design flexibility. Different sizes and shapes of foam components can be flexibly spliced ​​according to different application scenarios. After splicing, the connecting tabs 2 and adhesive blocks 4 are then used to bond and fix the required parts. During use, a polyurethane waterproof layer 6 prevents moisture from penetrating into the foam body 1. Polyurethane is an effective... Waterproof materials prevent water from penetrating into the foam body 1, thus protecting the internal conductive structure from moisture and avoiding potential dangers and equipment damage. Subsequently, carbon nanotubes and graphene conductive materials filled in the elastic conductive intermediate layer 7 are combined into a composite material as a conductive intermediate layer, which can provide extremely high conductivity, making it excellent for applications requiring conductivity. The metal plating layer 8 and conductive polymer fiber layer 9 can improve the flexibility and elasticity of the foam. The polymer fiber has good flexibility and can adapt to different shapes and pressures, enabling the foam to maintain good deformation recovery ability when subjected to external forces.

[0025] The technical scope of this utility model is not limited to the content described above. Those skilled in the art can make various modifications and variations to the above embodiments without departing from the technical concept of this utility model, and all such modifications and variations should fall within the protection scope of this utility model.
