Abstract

The invention relates to an electric conduction plastic wire material for electrical arc spray coating, and a preparation method thereof. The electric conduction plastic wire material comprises a plastic substrate and a carbon material electric conduction substance, wherein the carbon material electric conduction substance is continuously distributed in the plastic substrate along the axial direction. The preparation method comprises: (1) completely mixing the molten-state or powder-state plastic substrate and the carbon material electric conduction substance powder to obtain a mixture; and (2) carrying out wire production on the mixture on a wire production device to obtain the electric conduction plastic wire material for electrical arc spray coating. The electric conduction plastic wire material of the present invention is suitable for electrical arc spray coating, and can be used for the anti-corrosion anti-wear coating of the metal equipment so as to substantially improve the service life of the metal equipment.

Description

technical field [0001] The present invention generally relates to a wire material for thermal spraying, in particular to a conductive plastic wire material for arc spraying and a preparation method thereof. Background technique [0002] Industrial equipment (such as containers, pipes, etc.) made of metal (such as steel) is prone to corrosion and wear during use. Using a thermal spraying process to prepare a layer of anti-corrosion and / or wear-resistant coating on the surface of metal equipment can effectively improve Service life of metal equipment. Common thermal spraying processes, such as flame spraying, plasma spraying, explosive spraying, etc., all use powder as thermal spraying materials, and these thermal spraying equipment have complex structures, many auxiliary equipment, high energy consumption, and are not easy to move on site. Arc spraying equipment has the advantages of small size, high efficiency, and easy on-site mobile operation, and is widely used in metal ...
