[0001] The utility model relates to the technical field of conductive foam, in particular to a flame retardant conductive foam. Background Art

[0002] Conductive foam is a special material that obtains good conductivity by wrapping conductive cloth on flame retardant sponge or mixing in fillers with good conductive properties. After a series of treatments, this material has excellent surface conductivity and can be easily fixed on various electronic products with adhesive tape.

[0003] However, with the development of science and technology, electronic products are constantly updated, their working components are becoming more and more sophisticated, the working speed and efficiency are getting higher and higher, and the heat generation is also getting higher and higher. Therefore, it is not only required to be equipped with corresponding heat dissipation foam, but also to have flame retardant ability to prevent the temperature from being too high, which may cause flammable products to become flammable. Therefore, a flame retardant conductive foam is proposed. Utility Model Content

[0006] The protective device includes flame-retardant through holes, a fire extinguishing agent bag, a conductive layer, a heat absorbing layer, a heat-conducting column, a flame-retardant layer and an outer protective layer. The interior of the foam layer is provided with flame-retardant through holes, the interior of the foam layer is movably connected with a fire extinguishing agent bag, the bottom of the foam layer is fixedly installed with a conductive layer, the bottom of the conductive layer is fixedly installed with a heat absorbing layer, the top of the heat absorbing layer is fixedly installed with a heat-conducting column, the top of the foam layer is fixedly installed with a flame-retardant layer, and the top of the flame-retardant layer is fixedly installed with an outer protective layer.

[0011] Furthermore, the material of the flame retardant layer is aramid fiber, and the material of the outer protective layer is metallized film.

[0012] Beneficial Effects

[0013] Compared with the prior art, the technical solution of this application has the following beneficial effects:

[0014] The flame retardant conductive foam can expose the adhesive layer by removing the release paper, and the device is fixed on the electronic product through the adhesive layer, and then the heat generated during the operation of the electronic product is absorbed by the heat absorption layer, and then the absorbed heat is discharged from the inside of the device through the heat conductive column to dissipate the heat of the electronic product, and the conductive layer has a conductive function. At the same time, due to the particularity of the conductive layer material, it can also play a certain electromagnetic shielding function. The flame retardant through holes opened inside the foam layer cooperate with the flame retardant layer to prevent combustion caused by excessive temperature, so as to achieve the purpose of preliminary flame retardancy.

[0022] Specifically, Figure 2 As shown, the ceramic fiber inside the heat absorption layer 404 not only has good high temperature resistance, but also has certain thermal conductivity, and can maintain stable performance in a high temperature environment. In addition, the ceramic fiber usually also has good flame retardant properties, which can prevent the spread of fire.

[0023] Specifically, Figure 2 As shown, the graphene film inside the conductive layer 403 has excellent conductive properties and extremely low resistivity, which is far superior to traditional metal materials. Arranging the graphene film inside the conductive foam can significantly improve its conductive properties. The graphene film not only has excellent conductive properties, but also has good electromagnetic shielding properties, which can effectively prevent electromagnetic interference and signal leakage, ensure the normal operation of electronic equipment and data security, and the graphene film can withstand extremely high temperatures without being damaged.

It can maintain structural stability at high temperatures, does not melt or drip, and can effectively prevent the spread of flames. At the same time, the aramid fiber also has good thermal conductivity, which can assist the conductive foam in dissipating heat and improve the overall thermal stability.

[0026] Specifically, Figure 2As shown, the metallized film inside the outer protective layer 407 refers to a film with metallic properties formed by depositing metal atoms or ions on the substrate surface or the film surface by physical or chemical methods. This film has excellent electrical conductivity, thermal conductivity and shielding properties.

[0027] In summary, the flame retardant conductive foam can expose the adhesive layer 2 by removing the release paper 3, and the device is fixed on the electronic product through the adhesive layer 2, and then the heat generated during the operation of the electronic product is absorbed by the heat absorption layer 404, and then the absorbed heat is discharged from the inside of the device through the heat conductive column 405 to dissipate the heat of the electronic product, and the conductive layer 403 has a conductive function. At the same time, due to the particularity of the conductive layer 403 material, it can also play a certain electromagnetic shielding function. The flame retardant through hole 401 opened inside the foam layer 1 cooperates with the flame retardant layer 406 to prevent combustion caused by excessive temperature, so as to achieve the purpose of preliminary flame retardancy. When the electronic product accidentally catches fire, the heat of the flame will melt the outside of the fire extinguishing agent package 402, and the fire extinguishing dust in the fire extinguishing agent package 402 can extinguish the flame, so as to achieve the purpose of flame retardancy, and then the conductivity of the device is increased through the outer protective layer 407, so as to achieve the purpose of high temperature resistance and flame retardancy.
