NOVELTY - A conductive ink comprises 5-50 pts. wt. water-based resin binder, 1-40 pts. wt. conductive filler, 1-50 pts. wt. swelling agent and 1-50 pts. wt. solvent. USE - The conductive ink is used for preparing plastic material, which is used for preparing electroplated plastic (all claimed) and for printing conductive points or conductive lines. ADVANTAGE - The conductive ink has good conductivity and good binding force. The electroplated plastic prepared using the conductive ink has good coating binding force, electrical conductivity, film layer uniformity, salt spray resistance and cold and heat shock resistance. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are included for: a method for preparing the conductive ink comprising mixing the raw materials of the conductive ink; a method for preparing a plastic material comprising providing a plastic substrate and the conductive ink, coating the conductive ink on the surface of the plastic substrate, and drying; the plastic material obtained by the above method comprising a plastic substrate and an ink layer formed on the surface of the plastic substrate; and an electroplated plastic comprising the plastic material and at least one metal plating layer, where the metal plating layer is formed on the side of the ink layer away from the plastic substrate, the metal of the metal plating layer is one or more of gold, silver, molybdenum, rhodium, palladium, copper, iron, tin, zinc, cobalt, nickel, chromium, cadmium, antimony, indium and bismuth.
