Abstract

The invention discloses an aqueous conductive ink. The aqueous conductive ink comprises, by mass, 20-30 parts of a water-soluble acrylic resin, 15-20 parts of water, 1-3 parts of an assistant, 10-30 parts of a dye, 4-8 parts of nanometer conductive carbon black, 2-4 parts of nanometer copper powder, 5-15 parts of ethanol, 5-10 parts of triethylamine and 3-5 parts of phosphor. The aqueous conductive ink has the advantages of environmental protection, good conductivity, and especially good bonding force with hard-to-brush glass, metals and plastic films. The granularities and the mutual matching of above conductive materials are optimized, and an epoxy silane coupling agent increasing the adhesion to a base material is added, so the aqueous conductive ink has excellent performances, the maneuverability is guaranteed, and a preparation method of the ink is obviously better than existing technologies.

Description

technical field [0001] The invention belongs to the technical field of ink, and in particular relates to a water-based conductive ink. Background technique [0002] Flexible circuits are key components to realize multi-function, integration, miniaturization and low cost of electronic information products. With the development of electronic products and equipment in the direction of light, thin, small, low cost, multi-functional, high reliability, etc., the amount of flexible circuits is increasing. Using conductive ink or conductive ink by printing or printing, in flexible The formation of conductive lines on insulating substrates has attracted extensive attention of researchers. Conductive ink can be divided into structural type and filling type according to its structure. The conductive inks currently used in the electronics industry are mainly composite conductive inks. The conductive fillers used are generally inorganic fillers, such as gold, silver, copper, nickel, ca...
