Problems solved by technology

However, there are large van der Waals forces and p-p stacking between graphene sheets, which are prone to agglomeration, which leads to the failure of the excellent performance of graphene, and also deteriorates the material performance, limiting its application.

Abstract

According to the novel waterborne graphene polyurethane coating provided by the invention, modified graphene is added into raw materials of the coating, the modified graphene is modified through hydroxyethyl methylacrylate and diethylene glycol, and hydroxyl and unsaturated double bonds are grafted on the surface of the modified graphene, so that on one hand, dispersion of graphene in the coating can be promoted; and on the other hand, the polyurethane emulsion can be combined with macromolecules in the polyurethane emulsion, so that the finally prepared coating has excellent comprehensive performance. In addition, the invention also provides a preparation method of the coating.

Description

technical field [0001] The invention relates to a novel water-based graphene polyurethane coating and a preparation method of the coating. Background technique [0002] Coatings can be divided into oily and water-based coatings according to the type of solvent. Oil-based paint is mainly used in my country at present, and various organic solvents are used as the medium for dispersion and dilution. As the society pays more and more attention to environmental protection, people pay more and more attention to the harm caused by volatile organic solvents contained in oil-based paints in recent years. Compared with traditional solvent-based oil-based paints, the environmental protection advantages of polyurethane water-based paints are very prominent. Water is used as the dispersion medium, which avoids or reduces the use of organic solvents in traditional oil-based paints. Under normal circumstances, the performance of polyurethane water-based coatings is often inferior to that...
