Abstract

The invention discloses conductive ink for printing. The conductive ink is prepared from the following substances in parts by weight: 20-30 parts of bisphenol A glycidyl ether epoxy resin, 4-5 parts of epoxy curing agent, 1-3 parts of nanometer silver powder, 4-6 parts of nanometer copper powder, 5-10 parts of malonic acid, 40-50 parts of tetrahydrofuran and 3-7 parts of polyethylene glycol. The conductive ink for printing disclosed by the invention is friendly to the environment, and good in conductivity, and especially has good binding force on difficult-to-print glass, metal and plastic films. According to the conductive ink, the epoxy curing agent is optimized. The conductive ink has the advantages that the conductive ink can be cured with epoxy resin at normal temperature, and is fire-retardant and non-toxic, and the cured product is high in strength and stability. Compared with the prior art, the conductive ink has significant progress. The electrical conductivity of the ink is improved by adopting the nanometer copper powder and the nanometer silver powder.

Description

technical field [0001] The invention belongs to the technical field of ink, and in particular relates to a conductive ink for printing. Background technique [0002] The traditional etching printing method needs to use ammonia-based etching solution to corrode the plate, the etching solution is highly polluting, and consumes more water when rinsing the plate. Nowadays, the voice of "low carbon" is getting higher and higher all over the world. It is imperative to promote the use of printed conductive ink instead of etching method, and "green" printed conductive lines are imperative. Avoiding the use of volatile organic solvents and developing environmentally friendly conductive inks for printing will inevitably attract more and more attention. Conductive inks with different conductivity fillers, and the research on adding conductive fillers to conductive polymers to improve the conductivity of inks have become the key development directions of printing inks.
