Abstract

The invention provides a nano-modified epoxy heavy-duty anti-corrosion coating which comprises a component A and a component B at a mass ratio of (8-10): 1, wherein the component A comprises the following raw materials in parts by mass: 35-50 parts of epoxy resin, 2-10 parts of a modified nano material, 5-20 parts of modified scale aggregate, 6-10 parts of a mixed solvent, 5-15 parts of a silane coupling agent, 2-8 parts of an antirust agent, 1-5 parts of an auxiliary agent, 5-10 parts of a filler and 3-12 parts of a pigment; and the component B comprises the following raw materials in parts by mass: 15-30 parts of a polyamide epoxy curing agent, 10-15 parts of a cashew nut oil modified epoxy curing agent and 35-50 parts of a mixed solvent. By applying the above formula, the compactness ofthe coating can be effectively improved, the corrosion resistance of the coating is enhanced, and the durability of the coating is improved.

Description

technical field [0001] The present application relates to the technical field of anti-corrosion coatings, in particular to a nano-modified epoxy heavy-duty anti-corrosion coating. Background technique [0002] Metal materials have high strength, homogeneity, and strong designability, so they have been widely used in various fields. However, metal materials are inevitably in contact with the external environment during use, so they are easily corroded by external corrosive media, thereby reducing the durability of the structure, shortening the service life, and causing unnecessary economic losses. [0003] At present, the more common method for metal anti-corrosion treatment is to apply a layer of paint on the metal surface to isolate the metal surface from the external corrosive medium. The main principle of using the coating for anti-corrosion is to isolate the medium from the substrate. [0004] However, the coatings used in the prior art often have pores. One of the por...
