[0042] The second aspect of the embodiment of the present application provides a method for preparing the above-mentioned water-based conductive ink, comprising the following steps:
[0043] After mixing the silver-coated copper powder, modified water-based acrylic resin, water-based amino resin, neutralizer, solvent, defoamer, wetting agent, dispersant and anti-blocking agent in the formula, the gradient speed-up mixing process is carried out to obtain Water-based conductive ink.
[0044] The preparation method of the water-based conductive ink provided in the second aspect of the application, the silver-coated copper powder, modified water-based acrylic resin, water-based amino resin, neutralizer, solvent, defoamer, wetting agent, dispersant and After the anti-blocking agent is mixed, the raw material components are mixed evenly through the gradient speed-up mixing process, and then the water-based conductive ink is obtained. The process is simple, the preparation time is sh...
