Abstract

The invention relates to an oxidized-graphene-based high-temperature-resistant double-component epoxy resin paint. The oxidized-graphene-based high-temperature-resistant double-component epoxy resin paint is made from a component A and a component B according to the mass ratio that the component A to the component B is 3 to 1, wherein the component A comprises the following ingredients in parts by weight: 100 parts of polyurethane modified epoxy resin, 30-60 parts of hydrogenated bisphenol A epoxy resin, 1-6 parts of modified oxidized graphene, 10-20 parts of aluminum oxide, 1-3 parts of an antioxidant, and 20-30 parts of a solvent; and the component B comprises the following ingredients in parts by weight: 6-10 parts of a phenolic aldehyde curing agent, 3-5 parts of an organic silicon curing agent and 10-30 parts of a solvent. Paint curing products have excellent high temperature resistance and excellent water resistance, besides, the flexibility, the heat conductivity, the oxidation resistance and the like of the epoxy resin paint are also improved, and requirements of the prior art are met.

Description

technical field [0001] The invention relates to an epoxy resin coating, in particular to a graphene oxide-based high temperature resistant two-component epoxy resin coating. Background technique [0002] Epoxy resin refers to the general term for compounds that contain two or more epoxy groups in their molecular structure and can form a three-dimensional network cured product in the presence of appropriate chemical reagents. It is an important class of thermosetting resins. As the resin matrix of adhesives, coatings and composite materials, epoxy resin is widely used in the fields of water conservancy, transportation, machinery, electronics, home appliances, automobiles and aerospace. Epoxy resin has strong cohesion, strong adhesion, small curing shrinkage, excellent electrical insulation, good stability, excellent chemical resistance, and the heat resistance of epoxy cured products is generally 80-100 °C. Heat-resistant varieties of epoxy resins can reach 200°C or higher. ...
