Problems solved by technology

The traditional method is to add thermally conductive fillers to the coating to improve the thermal conductivity of the coating. Therefore, in order to obtain a coating with higher thermal conductivity, it is necessary to increase the amount of thermally conductive fillers, but this leads to a decrease in the corrosion resistance of the coating.

Description

technical field [0001] The invention relates to a coating and a preparation method thereof, in particular to a graphene heat-conducting anticorrosion coating and a preparation method thereof. Background technique [0002] Under normal circumstances, anti-corrosion coatings do not conduct heat, but in some special working conditions, not only excellent anti-corrosion performance is required, but also good thermal conductivity. The traditional method is to add thermally conductive fillers to the coating to improve the thermal conductivity of the coating. Therefore, in order to obtain a coating with higher thermal conductivity, it is necessary to increase the amount of thermally conductive fillers, but this leads to a decrease in the corrosion resistance of the coating. . The thermal conductivity and corrosion resistance of coatings are a pair of contradictions and restrict each other. [0003] Graphene is a new type of two-dimensional nanosheet material, which is composed of...
