NOVELTY - Preparing a metal abrasion self-repairing protective agent involves separating a graphene oxide solution at low speed, taking an upper layer liquid to be used, and mixing upper layer liquid and shell powder in a mass ratio of 4-20:1. The mixed solution is freeze-dried to obtain a composite powder of fluffy graphene oxide and shell powder. The composite powder is heated under vacuum at 80-120 degrees C. The composite powder, vegetable pine oil, dispersion medium and dispersing agent are mixed weight ratio of 20:2:80-100:10-15, fully stirred, and then put into the shearing machine for carrying out a reaction at 40-45 degrees C for 30-40 minutes. The physical stirring of reaction product is carried out to obtain a finished product. USE - Method for preparing a metal abrasion self-repairing protective agent. ADVANTAGE - The method ensures good repairing effect of the metal abrasion self-repairing protective agent.
