▎ 摘  要

NOVELTY - Conductive slurry comprises 30-60 wt.% binder, 0.05-3 wt.% dispersant, 0.1-2 wt.% defoamer, 10-50 wt.% conductive filler and 0.1-30 wt.% diluent. The binder includes aqueous polyester resin emulsion and/or aqueous styrene-acrylic emulsion. The dispersant includes polyacrylate, hydroxyethyl cellulose, hydroxypropyl methyl cellulose, polyethylene oxide, polyacrylamide, sodium alginate and/or polycarboxylate. The defoaming agent incudes polysiloxane, polyether defoaming agent and/or organofluorosilicon compound. The conductive filler includes composite powder of graphene, carbon nanotube, and nano conductive carbon powder modified by coupling agent. The diluent is distilled water or ethanol. USE - The conductive slurry is useful for printing circuit and electromagnetic shielding field. ADVANTAGE - The slurry: has light and high conductivity, improved conductivity and storage stability; is aqueous, environment friendly; and also has excellent electrical conductivity, flexibility and moisture and heat resistance after cured at 80-120degrees Celsius. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for preparing conductive slurry.
