Abstract

The invention belongs to the technical field of corrosion-resistant materials, and in particular relates to a graphene silicon-acrylic emulsion corrosion-resistant coating material and a preparation method thereof. First, graphene is prepared by adopting the Hummers method, and then octamethylcyclotetrasiloxane, KOH , silane coupling agent, dimethylsulfoxide, hexamethyldisiloxane to prepare silicone prepolymer; finally use butyl acrylate, methyl acrylate, acrylic acid, styrene, N-methylolacrylamide, silicone Prepolymer solution, etc. to prepare graphene silicon acrylic emulsion corrosion-resistant coating material. The present invention can draw through the measurement of acid resistance, alkali resistance and salt resistance that the corrosion resistance of the film prepared by the silicon-acrylic emulsion added with graphene is stronger than that of the simple silicon-acrylic emulsion. , the mass loss of the film decreases, and when the content of graphene is 5%, the corrosion resistance of the graphene silicon acrylic emulsion corrosion-resistant coating material is the best.

Description

technical field [0001] The invention belongs to the technical field of corrosion-resistant materials, and in particular relates to a graphene-silicon-acrylic emulsion corrosion-resistant coating material and a preparation method thereof. Background technique [0002] Engineering materials undergo harmful chemical changes and electrochemical changes under the influence of the surrounding environment, losing their original excellent properties and becoming corrosion of materials. The common ones are metal material corrosion and carbon steel material corrosion. Iron material is the most widely used metal material, so the corrosion solution for iron products is the most common. Although carbon steel materials have the advantages of cheap price, simple manufacturing process, good plasticity, good toughness, and easy processing, carbon steel materials generally have the weakness of being easy to corrode. In order to solve this problem, scholars at home and abroad have developed ...
