▎ 摘  要

NOVELTY - Graphene conductive slurry comprises 0.5-15.0 wt.% graphene layer, 0.1-5.0 wt.% dispersant, 80-99.4 wt.% diluent and 10-40 wt.% organic resin. USE - Graphene conductive slurry. ADVANTAGE - The slurry is easy to disperse into diluent, and has good dispersion stability, improved slurry stability, good compatibility and low cost techniques. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are included for: (1) preparation of graphene conductive slurry comprising expanding graphite raw material, pre-dispersing expanded graphite raw material to obtain pre-dispersed graphite raw material, mechanically grinding to obtain fine graphite raw material, mechanically stripping fine graphite material, and centrifuging to obtain product; (2) application graphene conductive slurry comprising mixing 200 pts. wt. graphene slurry, 500 pts. wt. water epoxy resin emulsion, 50 pts. wt. de-ionized water, 100 pts. wt. calcium carbonate, 70 pts. wt. talc, 50 pts. wt. titanium pigment, 20 pts. wt. dispersant, wetting agent, delusterant, 3 pts. wt. antifoaming agent, 20 pts. wt. thickening agent and 5 pts. wt. multifunctional auxiliary agent, dispersing, stirring, adding aqueous epoxy resin curing agent, uniformly stirring and coating plate; and (3) preparation of graphene slurry comprising mixing 91.0 wt.% de-ionized water and 2.0 wt.% polyethylene oxide dispersant, drying and cleaning stirring tank, stirring for 30 minutes to completely dissolved, adding 7.0% graphene layer, high speed stirring for 120 minutes, placing into high speed emulsifying machine or colloid mill with 2.0 mm zirconia balls as medium, and dispersing under 1500 rpm for 5 times to obtain product.
