Embodiment Construction

[0032] In the present invention, an expandable high heat dissipation material and its corresponding preparation method are provided. Combine below figure 1 As shown, first, the prepared product expansion high heat dissipation material is described in detail.

[0033] Such as figure 1 Shown is a schematic diagram of an expandable high heat dissipation material. The expandable high heat dissipation material 100 is composed of a gel 110 and a high heat dissipation film 120 dispersed in the gel.

[0034] The gel 110 refers to that the colloidal particles or macromolecules in the sol or solution are connected to each other under certain conditions to form a spatial network structure. When the dispersion medium filled in the structural voids is a liquid, it is a liquid gel, and the structural voids When the dispersion medium filled in the medium is gas, it is an aerogel, and if the organic aerogel is further carbonized, it will form a carbon aerogel. The gel 110 described in the ...

Abstract

The invention provides an expanding high heat dissipation material and a preparing method thereof, and belongs to the technical field of heat dissipation. The heat dissipation material consists of gels and a high heat conduction membrane distributed in the gels, wherein the gels are liquogels, aerogels and carbon aerogels, the high heat conduction membrane is a graphite membrane or a graphene membrane with a width ranging from 0.001-10 millimeters and a length ranging from 0.1-300 millimeters, the high heat conduction membrane is, by mass, 0.1% to 0.3% of the total heat dissipation material. According to the expanding high heat dissipation material and the preparing method thereof, the expanding high heat dissipation material is obtained by applying the high heat conduction materials to gel products, therefore a novel and light high heat dissipation material is achieved.

Description

technical field [0001] The invention relates to the field of heat dissipation materials. Background technique [0002] Electronic products, machinery, electric power, communications, chemical industry and many other fields will generate different amounts of heat in the process of product processing, production and use. If the generated heat cannot be effectively dissipated, it may affect the processing and use of the product. [0003] The colloidal particles or macromolecules in the sol or solution are connected to each other under certain conditions to form a spatial network structure, and the structural voids are filled with liquid as a dispersion medium, which can also be gas in xerogels. Such a special dispersion The system is called a gel. When the dispersion medium is a liquid, it is called a liquid gel, and when the dispersion medium is a gas, it is called an aerogel. For aerogel, because the gas in its network space is a gas with very low thermal conductivity, it i...
