Abstract

The invention provides water-based conductive ink. The water-based conductive ink comprises the following components in percentage by mass: 30-38% of deionized water, 15-20% of water-based acrylic resin, 6-10% of propylene glycol methyl ether, 10-16% of carbon nanotubes, 5-9% of conductive carbon black, 20-30% of ethanol, 1-3% of sodium p-octadecyl toluene sulfonate, 2-5% of triethanolamine, 0.5-1.5% of a dispersant and 0.5-1% of wax powder. The water-based conductive ink overcomes the defect of non-conductivity of the traditional ink, has the advantages of stable electrical conductivity, good resistance to bending and strong adhesive force, and can be applied to drawing of water-based circuit boards; and due to the high electrical conductivity and low conductive resistance, the water-based conductive ink can be flexibly used, and the flexibility of design is improved.

Description
