Description

technical field [0001] The invention relates to the technical field of preparation of conductive carbon paste, in particular to an environment-friendly low-resistance graphene carbon fiber conductive carbon paste and a preparation method thereof. Background technique [0002] Conductive carbon paste is a viscous slurry formed by uniformly distributing carbon-based particles of non-metallic conductor materials in thermoplastic or thermosetting resins. It is also customarily called carbon-based conductive ink. After the carbon paste is screen-printed and heated and cured (generally lower than 150°C), the resulting graphic film has good electrical conductivity, is not easily oxidized, has stable performance, and is resistant to acid, alkali and solvent corrosion. It has strong adhesion to the substrate, anti-peeling, and is suitable for substrates of different materials such as PET. The square resistance of conductive carbon paste is generally greater than 30Ω / sq. Compared wit...
