AI Technical Summary

Problems solved by technology

[0008] Since silver powder is a precious metal, the cost of conductive ink is high
In addition, silver paste ink is prone to silver ion migration during use, that is, in a humid environment, silver is electrolyzed under the action of an electric field, and positively charged metal silver cations move to the cathode, and finally a short circuit fault occurs
All of these limit the application of silver paste ink

Abstract

The present invention discloses a conductive ink which is good in conductivity, stable in performance and low in cost, and a preparation method thereof. The conductive ink includes the following components: by weight ratio, 40 to 68 parts of conductive particles, 30 to 58 parts of organic carriers, and 1 to 7 parts of auxiliaries.

Description

technical field [0001] The invention relates to a conductive coating composition, which belongs to the technical field of electronic materials. Background technique [0002] Conductive ink is an important electronic material, which is more and more widely used in membrane switch panels, keyboards, flexible conductive cables, electronic shielding, radio frequency identification (RFID) and other fields. [0003] Conductive inks usually consist of conductive fillers, organic polymer carriers, modifying additives and solvents. Among them, conductive fillers include carbon powder and metal powder, wherein carbon powder includes carbon black, graphite, etc., and the cost is low, but the conductivity is poor and the application range is small. Metal powders have good electrical conductivity, and the common ones are silver, copper, nickel, aluminum, iron, etc. However, except silver powder, other metal powders are easy to oxidize and reduce conductivity. Therefore, silver powder i...
