Abstract

The invention provides high-performance water-based epoxy anticorrosive coating. The coating comprises a component A and a component B. The component A is prepared from the following components in parts by weight: 60-70 parts of waterborne epoxy resin emulsion, 5-8.5 parts of styrene-acrylic emulsion, 2-3.5 parts of a zinc oxide / graphene oxide composite material, 0.5-1.2 parts of cerium-doped nanotitanium dioxide, 1-2 parts of nano attapulgite, 3-5 parts of organic bentonite, 0.2-3 part of pigment, 0.3-0.5 part of a silane coupling agent, 2-3 parts of n-butyl alcohol, 0.3-0.6 part of a dispersing agent, 0.3-0.5 part of a defoamer, 0.2-0.4 part of a leveling agent and 18-25 part of deionized water. The component B is prepared from the following components in parts by weight: 30-35 parts ofpolyether amine, 3-5 parts of diethylenetriamine, 25-32 parts of wet sericite powder and 8-12 parts of talcum powder. The anticorrosive coating is environmentally friendly, all the raw materials arematched with one another, and the prepared coating is good in anticorrosive effect, excellent in mechanical property and high in adhesive force.

Description

technical field [0001] The invention relates to the technical field of coatings, in particular to a high-performance water-based epoxy anticorrosion coating. Background technique [0002] As one of the thermosetting resins, epoxy resin has the advantages of good anti-corrosion performance, excellent adhesion, excellent physical and mechanical properties, good electrical insulation performance and strong chemical resistance and stability, and is widely used in the field of heavy-duty anti-corrosion coatings. Epoxy coating products are mainly solvent-based, which have the disadvantages of volatile organic solvents and easy environmental pollution during production and use. The development of waterborne epoxy coatings is one of the effective ways to avoid the use of organic solvents or reduce the content of organic solvents. The key technology for the preparation of water-based epoxy coatings is the water-based epoxy resin base material, that is, using an aqueous solution inst...
