Heat dissipation coating based on graphene and preparation method thereof

Abstract

The invention provides heat dissipation coating based on graphene and a preparation method thereof. The heat dissipation coating based on the graphene, is mainly prepared from a component A and a component B at the mass ratio of (4 to 12) to 1; the component A is prepared from the following components in parts by mass: 15 to 25 parts of resin, 20 to 45 parts of a solvent, 2 to 5 parts of an auxiliary agent, 0.01 to 5 parts of graphene powder and 30 to 50 parts of filling; the component B is prepared from a solvent, an accelerant and a curing agent; the mass ratio of the solvent to the accelerant to the curing agent is (6 to 14) to (0.6 to 1.4) to (25 to 40). According to the heat dissipation coating based on the graphene, provided by the invention, the heat conductivity and the heat radiation rate are improved and the rapid heat dissipation effect is realized.

Description

technical field [0001] The invention relates to the technical field of heat dissipation coatings, in particular to a graphene-based heat dissipation coating and a preparation method thereof. Background technique [0002] In the information age of the 21st century, all kinds of information are being transmitted all the time. People's pursuit of electronic components is more miniaturized and lightweight, and the input power of electronic components must be greatly increased to meet the demand. The increase in input power leads to a sharp increase in the heat flux density of the chip, which seriously affects the service life of the chip. Therefore, the heat dissipation problem of electronic components has become a technical bottleneck in the development of electronic devices. [0003] Usually, heat sinks, air cooling, liquid cooling, and heat pipes are added in electronic equipment to dissipate the heat in the equipment. In the case of large equipment space, heat sinks and air...
