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.
