Abstract

The invention belongs to the technical field of coatings, and particularly relates to a graphene heat dissipation coating as well as a preparation method and application thereof. The graphene heat dissipation coating comprises organic silicon modified acrylic resin, amino resin, polycarbonate resin, graphene, auxiliaries, a filler and water, has good scratch resistance, wear resistance and heat dissipation performance, and has the advantage of being environmentally friendly due to the fact that all the components are environmentally friendly. When the graphene heat dissipation coating is used for heat dissipation of an electric appliance, a relatively good heat dissipation effect can be provided for the electric appliance, the problems of paint peeling and the like caused by overlong service time of the electric appliance can be avoided, and the graphene heat dissipation coating has a good application prospect and market value.

Description

technical field [0001] The invention belongs to the technical field of coatings, and in particular relates to a graphene heat dissipation coating and a preparation method and application thereof. Background technique [0002] During the operation of electrical appliances, there are many reasons that cause electrical heating, such as: when the current flows through the conductive parts inside the electrical appliance, the capacitive effect of insulating materials loaded with alternating voltage, frictional heating between moving parts, and so on. If the heat dissipation is not timely or the heat dissipation effect is not good, it will cause overheating of the electrical appliances, and the life of the electrical appliances will be shortened and malfunction, and the consequences such as explosions and fires will occur in severe cases. Therefore, it is essential to provide proper heat dissipation for electrical appliances. [0003] At present, the problem of heating of electri...
