Abstract
In order to improve the anti-friction performance of water-based flexographic ink, we made up different kinds of water-base flexographic ink by changing the kinds of film-forming resin or adding different kinds of friction resistant additives, and then evaluated the friction resistant performance of the ink by the rate of density decay. According to analysis the influencing factors of the anti-friction performance of ink, aiming at improving the cohesion of molecular systems and smooth degree of membrane surface, and reducing the friction coefficient as well. The result shows that different molecular structure of film-forming resin ink will cause different cohesion of molecules system in ink, which impacts the ink friction performance. Adding appropriate anti-friction performance additives can improve ink cohesion of molecular system, and improve the ink anti-friction performance as well.
