▎ 摘　　要

NOVELTY - The method involves providing (S1) sugar as the raw material of a graphene quantum dot corrosion inhibitor. The water is provided as a solvent. A hydrothermal method is provided. The initial product is prepared by heating at 170-220 °C for 2-5 hours. The initial product is processed by centrifugation, filtration and drying to obtain solid graphene quantum dots. A hydrochloric acid or sulfamic acid solution with a concentration of 5% to 30% is configured (S2) as an acid solution. The graphene quantum dot corrosion inhibitor is added (S3) to the acid solution. The stirring and dissolving are performed. The obtained uniform solution is the rust remover containing the graphene quantum dot corrosion inhibitor. The carbohydrates are provided with one or more of glucose, soluble starch, fructose, and sucrose. The hydrothermal method is carried out in a hydrothermal reaction kettle with a polytetrafluoroethylene lining. USE - Preparation method of rust remover containing graphene quantum dot corrosion inhibitor used in chemical and material scientific preparation and application field for cleaning of carbon steel, copper and other metal. ADVANTAGE - The method provides rust remover with low cost, high degradation, high slow release efficiency and good rust removing effect. The method has simple operation, low cost under the protection of the graphene quantum dot corrosion inhibitor, realizing efficient cleaning of carbon steel, copper and other metal, at the same time, not damaging the metal substrate.
