Graphene modified aqueous epoxy heavy anti-corrosion coating and detection method thereof

Abstract

The invention discloses a graphene modified aqueous epoxy heavy anti-corrosion coating which is prepared by mixing a component A and a component B in a weight ratio of 4:1, wherein the component A comprises 40-50 parts of a bisphenol A aqueous epoxy emulsion, 0.5-2 parts of graphene, 4-8 parts of aqueous zinc phosphate, 4-8 parts of aqueous zinc molybdate, 10-15 parts of iron oxide red, 1-2 parts of fumed silica, 1-2 parts of nano zinc oxide, 5-10 parts of mica iron oxide red, 1-2 parts of an organic corrosion inhibitor, 1-2 parts of a 179 anti-flash rust agent, 0.3-0.6 part of a 190 dispersant, 0.3-0.5 part of a 1008 wetting agent, 0.5-1.5 parts of a BYK-011 defoamer, 0.3-0.5 part of a 7580 foam inhibitor, 0.1-1.5 parts of a BYK420 anti-sagging auxiliary agent, 0.3-0.5 part of an AMP-95 pH regulator and some deionized water; the component B is a polyamine addition product aqueous epoxy curing agent. The coating disclosed by the invention has excellent physical property and excellent chemical resistance, in particular salt fog resistance; a film with the coating is firm and tenacious and wear-resistant, is high in adhesive force and construction adaptability and has very good environment-friendliness.

Description

technical field [0001] The invention relates to the field of anti-corrosion coating of metal materials, in particular to a graphene-modified water-based epoxy heavy-duty anti-corrosion coating and a detection method thereof. Background technique [0002] In the development of anti-corrosion coatings, the country has played a great role in promoting the development of anti-corrosion coatings industry in terms of energy conservation and emission reduction, environmental protection, and low-carbon construction. At the same time, it has also put forward higher requirements for the anti-corrosion coatings industry. Require. With the continuous improvement of environmental awareness, paint companies are urged to develop alternatives to traditional solvent-based coatings (water-based anti-corrosion coatings, etc.); to develop alternatives to traditional heavy-pollution, toxic anti-corrosion coatings containing heavy metal pigments (such as the development of composite phosphate ant...
