White conductive ink composition and preparation method thereof

The invention relates to a white conductive ink composition and a preparation method thereof. The white conductive ink composition comprises the following components in parts by weight: 100 parts of polyester resin, 200-500 parts of organic solvent, 30-500 parts of conductive filler, 30-500 parts of nonconductive filler and 5-25 parts of ink additive. The white conductive ink composition has good conductivity and excellent high-temperature thermal aging resistance, mainly can be printed on glass, ceramics, metals, hard plastics, mobile phone protection pates and the like, replaces conventional white conductive ink, and improves and supplements the conductivity on a flexible circuit.
