Abstract

Abstract

Electrothermal coating is a kind of functional coating which can directly convert electric energy into heat or radiation energy on the basis of conductive coating. A waterborne epoxy two-component thermal coating system with modified carbon fiber and graphene as conductive filler was studied. Scanning electron microscopy (SEM) was used to characterize the surface and section of the coating. It was found that the carbon fibers were evenly distributed in the coating, forming a good conductive and heat transfer network.The thermal conductivity test results show that the thermal conductivity coefficient of the coating is 0.40 W / (m·K). The temperature rise curve of the coating increased regularly in three stages, and reached the peak value in 15~28 min, and the theoretical thermal efficiency reached 63.02%. The safe voltage of the coating is 24 V, and it has good insulation performance, which can guarantee the use safety.
