Abstract

The invention discloses a graphene infrared heat radiation coating and a preparation method thereof. The graphene infrared heat radiation coating comprises, by mass, 20-45% of film forming resin, 1-10% of graphene, 30-50% of an infrared radiation functional one-dimensional nano-material, 1.5-5% of a hard functional auxiliary filler, and 0-3% of a resin curing agent. Two-dimensional graphene is compounded with the one-dimensional infrared radiation functional filler, and the hard functional material is assisted, so the above three materials have synergistic effects to make a coating layer formed by the graphene infrared heat radiation coating have high radiance, high surface-directional heat conduction coefficient and excellent wear and scratch resistance. The preparation method has the advantages of guaranteeing of the stable performances of a coating dispersion system, easy control of technologic conditions, realization of stable performances of the prepared graphene infrared heat radiation coating, and effective reduction of the production cost.

Description

technical field [0001] The invention relates to the field of coatings, in particular to a graphene infrared heat dissipation coating and a preparation method thereof. Background technique [0002] With the development of science and technology, people have increasingly strong demand for electronic devices such as light weight, small size, and portability, and electronic devices are gradually developing in the direction of miniaturization, intelligence, and high power. This has also led to the heat dissipation of electronic devices gradually becoming the bottleneck of development. The heat dissipation problem has not been solved, and the power and volume of electronic heaters continue to increase, and the heat dissipation problem has been paid more and more attention. However, most of this heat dissipation method realizes heat dissipation through conduction and convection, and the heat dissipation efficiency is not high. Especially when the difference between the ambient temp...
