Abstract

The invention discloses a double-component conductive ink and a preparing method thereof. The double-component conductive ink is prepared from, by mass, 6-30 parts of conductive filler, 6-15 parts of resin, 0.5-1.5 parts of a dispersing agent, 1-5 parts of an auxiliary and 48.5-85 parts of a solvent. The preparing method of the double-component conductive ink comprises the following steps that firstly, a part of the solvent is taken and mixed with the resin through stirring until a transparent bonding material is obtained; secondly, the bonding material, the conductive filler, the auxiliary, the dispersing agent and the rest of the solvent are added into a ball grinder, and ball milling beads are added for grinding for 3-10 h after the conductive filler is wetted; thirdly, the ground material is filtered, and the finished product conductive ink is obtained. By means of the double-component conductive ink and the preparing method thereof, the problem that the preparing process and the preparing period of conductive ink are long in the prior art is solved, and the conductive ink has better conductivity and higher dispersibility.
