Abstract

The invention provides a silicone acrylate emulsion and graphene oxide-modified inorganic paint and a preparation method thereof. The paint is an anticorrosion priming paint which takes an alkali metal aqueous solution as a film forming substance, takes graphene oxide and zinc dust as a main filling material, and takes the silicone acrylate emulsion as a modifier. The silicone acrylate emulsion is obtained by the processes that an appropriate auxiliary agent is added in an organosilicon monomer containing an unsaturated bond as well as an acrylic acids monomer, and the materials are polymerized through a core-shell coating polymerization technology; flexibility of a film is improved when the emulsion is added in the inorganic paint, and Van der Waals force of a coating on a base material is increased. and the graphene oxide has excellent conductive performance and mechanical property. The experiment proves that flexibility, salt fog resistance, adhesive force and conductivity of the paint are obviously increased.
