A conductive carbon black coating liquid, comprising the following components in parts by mass based on total weight: 23-25 parts of a conductive filler containing carbon black; 1-1.5 parts of an acid polyester polyamide solution; 0.8-1.0 part of N-2-(taurine)-3-aminopropyltriethoxysilane; 0.5 part of dimethylsiloxane; 1.8-2.0 parts of a liquid-type blocked isocyanate; 1.3-1.5 parts of 2-phenylimidazole; 1.5 parts of a melamine resin; and the balance of a thermoplastic resin. A conductive thin film comprises a first release layer (1), a conductive carbon black coating (2), an electrodeposition copper foil layer (3), a conductive adhesive layer (4), and a second release layer (5) which are successively arranged, and the conductive carbon black coating (2) is made from the conductive carbon black coating liquid. |
