Conductive ink for mobile phone antenna

The invention provides conductive ink for a mobile phone antenna. Based on the total weight of the conductive ink as the reference, the conductive ink is mainly composed of the following ingredients, by weight, 10-20% of modified epoxy resin, 50-70% of silver powder, 10-30% of a solvent, 0.5-2% of a dispersant, 0.5-2% of an antifoaming agent, 0.5-1% of a thixotropic agent and 2-5% of a coupling agent. Resistance value of the conductive ink provided by the invention is low and stable. The conductive ink is environmentally friendly, is safe to use, has excellent adhesive force, chemical resistance and stability, and has a good application prospect.
