Problems solved by technology

The main reason is that traditional coatings have poor high temperature resistance and low thermal conductivity, which leads to poor heat transfer in anti-corrosion environments and poor corrosion resistance at high temperatures, which makes many production equipment unable to work normally.
The poor heat dissipation effect of traditional coatings not only restricts the use of traditional industrial chemical equipment, but also causes many problems when used in high-power electrical appliances, automobiles and other fields

Description

technical field [0001] The invention belongs to the technical field of coatings, in particular to a heat-conducting anti-corrosion coating based on graphene functional materials and a preparation method thereof. Background technique [0002] Chemical equipment, oil and gas pipelines, steam pipelines and other equipment are in harsh environments with high humidity, high salinity, and high temperature. This requires that the coatings used not only have good anti-corrosion performance, but also put forward higher requirements for their thermal conductivity. At present, although anti-corrosion coatings are widely used in the petrochemical field, they are mainly concentrated on the outer walls of oil tanks and pipelines, and less used in heat exchangers and steam pipelines. The main reason is that traditional coatings have poor high temperature resistance and low thermal conductivity, which leads to poor heat transfer in anti-corrosion environments and poor corrosion resistance ...
