Embodiment 1

[0035] Please refer to image 3, the present embodiment is a kind of flow chart that adopts graphite fiber to manufacture novel high thermal conductivity and heat dissipation coating, it can be seen that it mainly includes the following steps:

[0036] S201: Cut the graphite fiber made by spinning into short graphite fiber;

[0037] Graphite fiber is made by spinning, and the short graphite fiber is cut or crushed according to a preset length through a special tool (such as a gantry knife) or a gas crusher. Of course, in order to better combine with the base resin, before preparing short graphite short fibers, it is necessary to do surface treatment on the graphite fibers according to different resins to improve the performance of the composite material.

[0038] If necessary, it is also necessary to put the treated short graphite fiber into a grinder for grinding; the ground graphite fiber is obtained by further processing the chopped graphite fiber, and generally the choppe...

Abstract

The invention provides a novel high heat conduction and heat dissipation coating and a manufacturing method thereof. The coating is applied in the heat dissipation field of electronic products, and comprises basic resin and filler, wherein the basic resin is coating resin, and the filler comprises one or more of graphite, nanographite, flake graphite, graphene, pyrolytic carbon, pyrolytic graphite, graphite powder, carbon nano tube, carbon fiber, graphite fiber, ceramic fiber, quartz fiber, metal fiber, zirconia, boron nitride, silicon nitride, boron carbide, carborundum, magnesium oxide powder, metasilicic acid fiber, calcium silicate aluminum fiber, alumina fiber, and copper, aluminum, silver, tungsten and molybdenum metal powders. The coating prepared according to the material and the method disclosed by the invention is directly coated or sprayed on the surface of a heat dissipater, heat is transmitted onto the coating, and then the heat is dissipated to the space by the coating so as to accelerate the dissipation of heat generated by an electronic device and avoid the problems of performance reduction or instability, service life shortening and the like of the electronic device due to insufficient heat dissipation.

Description

technical field [0001] The invention relates to the application of a polymer composite material, in particular to a novel high thermal conductivity and heat dissipation paint made of a polymer composite material and a processing and manufacturing method for the novel high heat conduction heat dissipation paint. Background technique [0002] Thermally conductive and heat-dissipating coatings are widely used in fields that require heat dissipation, such as computers, notebook computers, LED lighting, communications, rectifiers, medical and industrial equipment, and are mainly coated on the surface of radiators. However, with the expansion and popularization of the application range of electronic and electrical equipment, the performance and structure requirements of electronic and electrical equipment are becoming more and more stringent and complex, including higher processing speed, higher processing frequency, smaller Smaller size, lighter weight, higher power and other tec...
