▎ 摘　　要

NOVELTY - Graphene-modified aqueous conductive ink comprises 10-40 pts. wt. aqueous resin, 10-30 pts. wt. water, 5-25 pts. wt. cosolvent, 1-10 pts. wt. additive, 30-80 pts. wt. conductive carbon black and 0.1-20 pts. wt. graphene. USE - Graphene-modified aqueous conductive ink (claimed). ADVANTAGE - The graphene-modified aqueous conductive ink is environmentally-friendly, has excellent thermal conductivity, mechanical property, bending resistance, adhesive force, stripping resistance and acid-, alkali- and chemical solvent-corrosion resistance and high flexibility, prevents the printing product from oxidation after being cured, can replace the oily product, reduces the usage and emission of the organic solvent, and reduces the emission of volatile organic compound. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for the preparation method of graphene-modified aqueous conductive ink, which involves (a) weighing the raw materials, adding the weighed raw materials to a dispersing kettle, stirring, uniformly pre-dispersing the mixture, transferring the pre-dispersed material to a mill to carry out crushing until the fineness of the material is less than or equal to 10 microns, and filtering the crushed material to obtain graphene-modified aqueous conductive ink.
