Abstract

The invention provides a graphene conductive printing ink. The graphene conductive printing ink comprises, by weight, 4.71 to 5.62% of phenolic resin, 83.12 to 84.08% of graphene, 2.6 to 3.5% of ethyl cellulose, 4.26 to 4.75% of ethanol, 1.2 to 1.36% of Al2O3 powder and 3.13 to 3.42% of SiO2 powder.

Description

technical field [0001] The invention relates to a conductive ink, in particular to a graphene conductive ink. Background technique [0002] Graphene is widely used in conductive coatings and thermally conductive materials because of its excellent electrical and thermal conductivity. For example, the Chinese invention patent with the notification number CN103113786B discloses a graphene conductive ink, which includes the following components and the mass percentages of each component are: resin 0.01%-25%; graphene 0.1%-95%; 0.1%-30.0% solvent; 5.0%-99.79% solvent; the Chinese invention patent with the notification number CN103319954B discloses a graphene conductive ink, which consists of the following components by weight percentage: graphene 0.001wt%-80wt%; Linking material 1wt%-60wt%; auxiliary agent 0.1wt%-30wt%; the balance is solvent. [0003] However, after the above-mentioned graphene conductive ink is used in printed circuits, because of its low strength, it is easy...
