Abstract

The invention discloses a wearing-resistant double-component graphene anti-corrosion coating and belongs to the technical field of macromolecule anti-corrosion materials. The method comprises the following steps: sequentially weighing the following components in parts by weight: 25-40 parts of an epoxy resin, 15-22 parts of a solvent, 3-5 parts of a leveling agent, 2-4 parts of a defoaming agent,3-5 parts of a dispersant, 12-16 parts of zinc powder, 10-15 parts of coarse whiting and 20-28 parts of modified graphene; mixing the epoxy resin with the solvent, adding the leveling agent, the defoaming agent, the dispersant, the zinc powder, the coarse whiting and the modified graphene, and conducting stirring and mixing so as to obtain a component A; sequentially weighing the following components in parts by weight: 10-15 parts of a curing agent and 5-6 parts of a solvent, mixing the curing agent with the solvent, and conducting stirring and mixing so as to obtain a component B; separatelypackaging the component A and the component B, so as to obtain the wearing-resistant double-component graphene anti-corrosion coating. The wearing-resistant double-component graphene anti-corrosion coating disclosed by the invention is excellent in wearing resistance and corrosion resistance.

Description

technical field [0001] The invention discloses a wear-resistant two-component graphene anticorrosion coating, which belongs to the technical field of polymer anticorrosion materials. Background technique [0002] In recent years, with the rapid development and high-speed construction of cities, a large number of metal materials have been used in infrastructure, energy, chemical industry, construction, transportation and other fields, and the ensuing metal corrosion has become more and more serious. It has brought a lot of inconvenience to people's work and life, and caused huge losses to the national economy. However, traditional anti-corrosion coatings have problems such as large environmental pollution, single anti-corrosion effect, and poor anti-corrosion effect, which make them unable to meet the needs of industry development. Therefore, it is imperative to develop a new type of high-efficiency anti-corrosion coating. The anti-corrosion filler in some existing graphene-...
