▎ 摘　　要

NOVELTY - A light carbon-based electromagnetic shielding paint comprises 10-25 wt.% electromagnetic shielding filler, 2-5 wt.% electromagnetic shielding filler dispersant, 28-40 wt.% polyurethane modified epoxy resin, 4-8 wt.% curing agent, 25-35 wt.% rare material and 2-5 wt.% auxiliary agent. The electromagnetic shielding filler comprises three-dimensional graphene and/or nickel-plated carbon nanotube. USE - Light carbon-based electromagnetic shielding paint. ADVANTAGE - The paint reaches purpose of keeping high shielding efficiency and reducing density, promotes uniform dispersion of nickel-plated carbon nanotube in resin system, and improves electromagnetic shielding performance and conductivity. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for a method for preparing of light carbon-based electromagnetic shielding paint comprising dissolving dried polyurethane modified epoxy resin by dilute material, adding electromagnetic shielding filler, electromagnetic shielding filler dispersant and auxiliary agent, uniformly dispersing to obtain electromagnetic shielding filler dispersion, uniformly mixing electromagnetic shielding filler dispersion, adding curing agent and uniformly stirring.
