High-performance aqueous graphene paint and preparation method thereof

The invention discloses high-performance aqueous graphene paint and a preparation method thereof. The preparation method of the high-performance aqueous graphene paint comprises the following steps of: oxidizing natural graphite in an oxidant, adopting a two-step chemical reduction method to obtain organic molecule-modified graphene aqueous solution; and adding polyester, a neutralizing agent, a flatting agent, an antifoaming agent, a cross-linking agent and a catalyst by adopting a solution co-mixing method to obtain aqueous graphene paint. A conductive coating with high conductive performance and mechanical performance is obtained by carrying out spray-coating, ink-jet printing and printing on the obtained paint, the conductive coating can be applied to the field such as electromagnetic shielding, static electricity preventing, corrosion preventing, radiating, wear-resisting and electronic circuits, and therefore, the application value is extensive.
