Description

Technical Field

[0001] This utility model relates to the field of microwave absorbing materials technology, and in particular to a combinable polystyrene foam microwave absorbing material structure. Background Technology

[0002] Polystyrene foam is lightweight, shock-resistant, has a uniform texture, and good thermal insulation properties, making it an ideal choice for microwave absorbing materials. Furthermore, its lightweight and efficient characteristics have led to its widespread application in electromagnetic compatibility (EMC) applications such as base station antennas and shielding boxes. However, with technological advancements, the performance requirements for microwave absorbing materials are constantly increasing. Traditional microwave absorbing materials often struggle to meet complex demands such as wide bandwidth, high strength, and lightweight design. Therefore, there is a need to design a combinable polystyrene foam microwave absorbing material structure.

[0003] To address this issue, patent CN206909035U discloses a microwave absorbing material comprising: a base layer; a ferromagnetic thin film layer disposed on the base layer, the ferromagnetic thin film layer and the base layer forming an absorption unit; and a rubber layer disposed on the absorption unit. By applying the technical solution of this invention, and by combining the ferromagnetic thin film layer, the base layer, and the rubber layer to form the microwave absorbing material, the microwave absorbing material can possess both the low-frequency absorption performance of the absorption unit and the high-frequency absorption performance of the rubber material, thereby increasing the frequency range of electromagnetic waves absorbed by the microwave absorbing material. Therefore, the technical solution of this invention can solve the problem of the narrow frequency range of electromagnetic waves absorbed by existing microwave absorbing materials.

[0004] While the aforementioned absorbing materials can solve the problem of narrow frequency range of electromagnetic wave absorption in existing absorbing materials, it is inconvenient to increase the length of the absorbing material according to the application scenario. Therefore, it is necessary to design a combinable polystyrene foam absorbing material structure. Utility Model Content

A connecting rod is fixed to one side of the combined rod. The mounting base is fixed to the outer wall of the protective edging away from the combined rod. A mounting groove is provided inside the mounting base.

[0009] A wave-absorbing structure is fixed at the top of the paint layer.

[0010] Furthermore, the substrate is a polystyrene foam layer, and the protective underlayer is a rubber sheet layer.

[0016] The present invention provides a combinable polystyrene foam microwave absorbing material structure, the advantages of which are:

[0017] With the addition of a combination structure, the two sets of microwave absorbing materials can be easily combined and connected by the interference fit between the combination rod and the mounting base. This makes installation convenient, time-saving, and labor-saving, and realizes that the device has the function of facilitating the combination and installation of microwave absorbing materials, thus improving the convenience of using the polystyrene foam microwave absorbing material structure.
