▎ 摘  要

NOVELTY - Aqueous dip-coated graphene self-drying paint comprises 50-70 wt.% styrene-acrylic emulsion, 2-10 wt.% film-forming aid, 0-1 wt.% defoamer, 0-1 wt.% leveling agent, 0-1 wt.% dispersant, 1-5 wt.% graphene, 0.5-3 wt.% liquid anti-rust pigment, 0-2 wt.% anti-flash rust agent, 0-2 wt.% thickener, and balance is water. USE - Aqueous dip-coated graphene self-drying paint. ADVANTAGE - The aqueous dip-coated graphene self-drying paint improves anti-settling performance of the dip-coated coating in a low viscosity state, improves anti-corrosion performance of the paint film, neutral salt spray test reaches more than 200 hours, improves hardness and scratch resistance of the paint film, improves scratch resistance significantly and has important application value. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a method for preparing aqueous dip-coated graphene self-drying paint, which involves: (A) pre-mixing dispersing agent, defoaming agent, film-forming aid with water, and adding graphene to disperse the pulp at high speed; (B) grinding slurry through a sand mill to a fineness below 15 micrometer; and (C) adding styrene-acrylic emulsion to the slurry and other additives under agitation to adjusting into a finished paint.
