Abstract

The invention relates to an electroconductive polymer printing ink for offset printing, gravure printing and screen printing. A conductive substance of the ink adopts a conducting polymer based on poly-ethylene-dioxythiophene. The electroconductive polymer printing ink comprises water-based polymer resin, conductive polymer aqueous dispersion solution, propanetriol, dimethyl sulfoxide, N,N-dimethylethanolamine and a water-based thickening agent. The invention also relates to a method for preparing the electroconductive polymer printing ink for offset printing, gravure printing and screen printing, which comprises the following steps: mixing the conducting polymer aqueous dispersion solution based on the poly-ethylene-dioxythiophene with the dimethyl sulfoxide according to the proportion; and mixing the water-based polymer resin with the water-based thickening agent according to the proportion for standby; adjusting pH of the mixture to be between 7.5 and 9.5; evenly mixing the mixture with the water-based resin; and adding the propanetriol into the mixture. The electroconductive polymer printing ink and the method have the advantages of thin thickness of an ink film, high printing precision and high printing speed, and also have the advantages of environmental protection, good electroconductive performance, high stability and the like.

Description

technical field [0001] The invention relates to conductive ink, more specifically, to a conductive polymer printing ink used for offset printing, gravure printing and screen printing and a production method thereof. Background technique [0002] Traditional inks are mostly solvent-based, and the pollution caused by volatile organic substances released during production and use is currently listed as the main pollution source in cities after cars. With the advancement of science and technology and the rapid development of the economy, the shortage of resources and energy has attracted the attention of countries all over the world. Saving money and energy and protecting the environment are the main problems facing the world's chemical industry. Non-toxic, non-polluting and environmentally friendly water-based inks will gradually replace solvent-based inks in the near future. The traditional production method of conductive ink is to use conductive silver paste or carbon paste,...
