▎ 摘　　要

NOVELTY - Salt spray-resistant powder coating comprises 50-65 wt.% graphene and carbon nanotube modified polyester resin, 10-30 wt.% polyaniline modified layered filler, 4-7 wt.% curing agent, 0.8-1.2 wt.% leveling agent, 0.7-28 wt.% pigment, 10-30 wt.% inorganic filler, and 0.5-2 wt.% auxiliary agent. USE - Salt spray-resistant powder coating used for characterizing relative strength of corrosion resistance of the material. ADVANTAGE - The salt spray-resistant powder coating has excellent salt-fog resistance and corrosion resistance, and prevents water vapor, oxygen, salt and other material permeation. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a method for preparing salt spray-resistant powder coating, which involves: pre-mixing raw materials in the mixing tank, extruding through the extruder, tabletting, pulverizing, grinding, sieving, and packaging to obtain a product.
