AI Technical Summary

Technical Problem

Existing water-based inks lack conductivity in smart printing, and traditional conductive inks are harmful to the environment, failing to meet the requirements of environmental protection and high conductivity.

Method used

Casein is used as a water-based binder, combined with conductive pigments such as conductive carbon black, conductive titanium dioxide, conductive graphene, and conductive carbon nanotubes. High-gloss water-based inks are prepared by modifying casein and using an environmentally friendly water-based system to achieve high-efficiency printing.

Benefits of technology

The prepared ink has high gloss, good adhesion and easy degradability, meeting the high-quality image reproduction requirements of intelligent printing, while being environmentally friendly and pollution-free.
