▎ 摘　　要

NOVELTY - Aqueous based self-repairing paint comprises 60-70 pts. wt. modified aqueous polyurethane emulsion, 10-20 pts. wt. aqueous acrylic emulsion, 0.1-0.3 pts. wt. antifoaming agent, 0.2-0.3 pts. wt. wetting agent, 1-2 pts. wt. wax powder, 3-5 pts. wt. film-forming auxiliary agent, 3-5 pts. wt. water and 0.1-0.2 pts. wt. thickening agent. The modified aqueous polyurethane emulsion is a modified graphene oxide modified aqueous polyurethane emulsion and the modified graphene oxide is polydimethylsiloxane modified graphene oxide USE - Used as aqueous based self-repairing paint comprising e.g. modified aqueous polyurethane emulsion. ADVANTAGE - The aqueous based self-repairing paint has high mechanical properties and good scratch resistance and self-healing capabilities. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for preparing aqueous based self-repairing paint comprising (1) preparing modified graphene oxide, (2) using the modified graphene oxide as a raw material to prepare a modified aqueous polyurethane emulsion and (3) mixing and stirring the modified aqueous polyurethane emulsion, aqueous acrylic emulsion, antifoaming agent, wetting agent, wax powder, film forming auxiliary agent, water and thickening agent to obtain a finished product
