▎ 摘 要
NOVELTY - Graphene aqueous gravure ink comprises 3-10 wt.% conductive filler, 1.5-10 wt.% aqueous resin, 2.5-40 wt.% water soluble resin, 2.5-40 wt.% aqueous emulsion, 0.1-1 wt.% dispersant, 1-5 wt.% auxiliary agent, and 44-89.9 wt.% alcohol solvent, where the conductive filler is composed of conductive carbon black and graphene formed by mixing according to mass ratio of 0.1-10:1. USE - Used as graphene aqueous gravure ink. ADVANTAGE - The gravure ink overcomes the environmental pollution caused by the traditional solvent, is non-combustible, non-toxic, less smell, strong glossiness, clear character, can quickly adapt to printing. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for preparing graphene aqueous gravure ink comprising (i) mixing the graphene dispersing agent, conductive carbon black and an aqueous resin into double-planetary type stirrer, firstly stirring for 10 minute/hour, at rotating speed of 100-1000 revolutions/minute, then stirring for 10-30 minutes at the rotating speed of 1000-10000 revolutions/minute to obtain premix, then dispersing premix for 30 minute to 5 hours to obtain dispersion, and (ii) adding water soluble resin in the preparative dispersing liquid, aqueous emulsion and auxiliary agent, agitating for 10 minutes/hour at a rotating speed of 100-1000 revolutions/minute to obtain the product.
