▎ 摘　　要

NOVELTY - Intrinsic self-healing anticorrosion coating comprises 80-90 wt.% polyurethane elastomer material, 7-18 wt.% acetone, 1-2 wt.% graphene, 0.5-1 wt.% leveling agent and 0.5-1 wt.% dispersant. USE - Intrinsic self-healing anticorrosion coating. ADVANTAGE - The intrinsic self-healing anticorrosion coating can repair itself or repair the damage under certain conditions after being damaged by the outside, and restore its original anti-corrosion effect. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a method for preparing an intrinsic self-healing anticorrosion coating, which involves: (a) synthesizing polyurethane elastomer material; (b) adding acetone to the three-necked flask as a solvent; (c)adding polyurethane elastomer material at a stirring speed of 200 revolutions per minute (r/min), mixing well; (d) adding graphene, adjusting the rotation speed to 500 r/min; (e) adding leveling agent and dispersant dropwise in order after fully stirring, and stirring for 10 minutes to obtain an intrinsic self-healing anti-corrosion coating.
