Description

Technical Field

[0001] This utility model belongs to the field of conductive foam, and specifically relates to a multifunctional conductive foam. Background Technology

[0002] Foam is a high molecular polymer material with many small pores. It is lightweight, elastic, and corrosion resistant, and is widely used in industrial manufacturing, electronic equipment, new energy, and many other fields.

[0003] However, traditional foam is easily ignited when exposed to a heat source and releases a large amount of toxic gases during combustion. For example, in the battery packs of new energy vehicles, traditional foam cannot effectively prevent fires caused by thermal runaway of the battery. At the same time, traditional foam is very easy to deform under pressure due to its lack of support, which affects the normal use of the equipment.

[0004] Therefore, there is an urgent need to design a new type of foam to solve the above problems. Utility Model Content

[0005] Purpose of the utility model: In order to overcome the above shortcomings, the purpose of this utility model is to provide a multifunctional conductive foam. Through the design of several air bladder strips, combined with the triangular grid structure of the foam layer, the support capacity is greatly improved. The two conductive cloth layers realize the conductivity of the foam. At the same time, the flame retardant cavity and flame retardant layer, together with the setting of vent holes, prevent the foam from being exposed to fire or overheating and burning, thus greatly improving the safety performance of the foam.

[0006] Technical Solution: To achieve the above objectives, this utility model provides a multifunctional conductive foam, comprising a foam layer, an airbag layer in the middle of the foam layer, flame-retardant layers on both sides of the foam layer, a plurality of flame-retardant cavities between the foam layer and the flame-retardant layers, a conductive cloth layer on the side of the flame-retardant layer away from the foam layer, and an airbag layer comprising a plurality of airbag strips arranged in parallel, each airbag strip comprising a plurality of airbags and a plurality of connecting holes, with the airbags and connecting holes spaced apart. The flame-retardant layers on both sides of the foam layer provide more comprehensive fire protection, and the flame-retardant cavities further isolate heat, reducing the impact of flames on the internal foam layer. Simultaneously, the airbag strip design effectively disperses pressure under external force, providing a uniform cushioning effect. Integrating multiple functions such as cushioning, flame retardancy, and conductivity, this greatly expands the application scenarios and effectiveness of the foam.

[0007] Furthermore, a release layer is provided on the side of the conductive fabric layer away from the foam layer. The release layer prevents the conductive fabric layer from adhering to the surface of other materials or equipment during processing, thereby ensuring the smooth progress of the processing; at the same time, the release layer allows the conductive foam to be easily peeled off the protective layer during installation, exposing the conductive fabric layer, which is convenient for bonding to the target surface.

[0008] Furthermore, several ventilation holes are provided on both sides of the foam layer; these ventilation holes penetrate the foam layer, flame-retardant layer, conductive fabric layer, and release layer. The design of these ventilation holes greatly improves the material's permeability, allowing air to circulate freely between the layers, which helps to quickly dissipate heat and reduce the operating temperature of the equipment.

[0009] Furthermore, the foam layer and the airbag layer, the foam layer and the flame-retardant layer, the flame-retardant layer and the conductive fabric layer, and the conductive fabric layer and the release layer are all connected by adhesive. Adhesive bonding enhances the adhesion between the layers, allowing them to work together to withstand external forces when subjected to stretching, compression, or bending.

[0010] Furthermore, the flame-retardant cavity is equipped with flame-retardant powder. During combustion, the flame-retardant powder absorbs a large amount of heat, reducing the surface temperature of the material, slowing down the combustion rate, and significantly improving safety during use.

[0011] Furthermore, the airbag is designed in a teardrop shape. The teardrop shape allows for a more uniform stress distribution when inflated or subjected to force, reducing localized stress concentration and thus lowering the risk of airbag rupture.

[0012] Furthermore, the foam filling within the foam layer employs a triangular mesh structure as its basic support unit. This triangular mesh structure ensures a more uniform stress distribution when the foam is subjected to external forces, reducing the risk of deformation or damage caused by stress concentration.

[0013] As can be seen from the above technical solution, this utility model has the following beneficial effects:

[0014] 1. This utility model provides a multifunctional conductive foam, which greatly enhances its support capacity through the design of several air bladder strips and the triangular grid structure of the foam layer.

[0015] 2. This utility model provides a multifunctional conductive foam. The two conductive fabric layers enable the foam to conduct electricity. At the same time, the flame-retardant cavity and flame-retardant layer, together with the setting of vent holes, prevent the foam from burning when it comes into contact with a fire source or overheating, greatly improving the safety performance of the foam.
