Abstract

A single acrylic resin has poor conductivity and toughness, but strong hydrophilicity, which limits its application in high-voltage transmission corona prevention. In response to this issue, this article investigates the preparation of four types of acrylic composite conductive coatings with different additions of carbon fiber powder, multi-walled carbon nanotubes, and nano titanium dioxide. Through experimental testing, compare and analyze the effects of various fillers on the mechanical properties, conductivity, hydrophobicity, and heat resistance of acrylic composite conductive coatings. The experimental results show that the acrylic conductive coating prepared with thermoplastic acrylic resin as the matrix, carbon fiber powder and multi-walled carbon nanotubes as conductive fillers, and nano titanium dioxide as a self-cleaning agent has excellent performance characteristics in all aspects, and is suitable for corona prevention in ultra-high voltage transmission. This acrylic composite coating can be used to repair burrs and scratches on the surface of transmission lines, fill gaps in stranded wires, and achieve the goal of reducing the local electric field of high-voltage transmission lines to prevent wire corona.
