▎ 摘  要

NOVELTY - A graphene shielding film paste comprises 3-50 pts. wt. aqueous polymer resin, 0.1-20 pts. wt. graphene powder, 15-35 pts. wt. carbon black, 0.1-2 pts. wt. carbon nanotubes, 0.1-30 pts. wt. conductive filler, 10-30 pts. wt. dispersant, 0.5-5 pts. wt. functional additive, and 20-45 pts. wt. deionized water. USE - The graphene shielding film paste is useful for shielding layer of signal transmission cable (claimed). ADVANTAGE - The graphene shielding film paste has excellent shielding performance. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are included for the following: (1) a method for preparing the graphene shielding film paste, which involves (S1) adding the above-mentioned components to a mixing tank, and (S2) placing the mixing tank on a dispersing machine, stirring and dispersing at a high speed of 300-1200 rpm for 20-30 minutes to prepare an alkaline graphene shielding film paste; and (2) use of the graphene shielding film paste for shielding layer of signal transmission cable.
