Abstract

The invention discloses a graphene heat dissipation coating, which is composed of the following components in mass part: 50-80 parts of epoxy acrylic resin, 5-10 parts of graphene, 60-80 parts of water, 10-15 parts of coloring agent, and 20-30 parts of auxiliary agent, wherein the coloring agent is one type or a mixture of multiple types from phthalocyanine blue, azo red and azo blue; the auxiliary agent comprises dispersing agent, defoaming agent, curing agent and adhesion promoter. The graphene heat dissipation coating is simple in preparation process and low in production cost, and can be cured at room temperature. The graphene is adopted as the main heat dissipation medium to provide channels for heat transfer, so that heat release is facilitated. The coating is applied onto the surface of a heat dissipation device, so that the heat dissipation area is increased, the heat dissipation effect is improved, and the characteristics of high efficiency and favorable environment friendliness are achieved.

Description

technical field [0001] The invention relates to a coating, in particular to a graphene heat dissipation coating, which belongs to the technical field of new coatings. Background technique [0002] As an industrial product, the main function of paint is decoration, and its function is relatively single. With the development of science and technology and the improvement of human living standards, traditional coatings with a single function can no longer meet the needs of reality. [0003] As a new type of coating, heat dissipation coating not only has the basic function of decoration, but also has the effect of improving heat dissipation efficiency, and has received extensive attention and research. However, most of the heat-dissipating coatings currently on the market use expensive heat transfer media as fillers. The production process is complicated and the cost is high, which is not conducive to the mass production and large-scale application of coatings. Contents of the...
