Abstract

The invention relates to the field of heavy-duty paint, and discloses metal flake type single-component water-based heavy-duty paint and a preparation method thereof. The water-based heavy-duty paintis prepared from the following raw materials in parts by mass: 40-60 parts of carbon titanium cage resin, 8-15 parts of rust-proof pigment, 20-30 parts of deionized water, 2-3 parts of a directional alignment agent, 1-3 parts of a dispersant, 1-2 parts of a defoamer, 0.5-1 part of a thickener and 0.5-1 part of a leveling agent. Selected metal flake such as aluminum flake and zinc aluminum alloy flake or aqueous aluminum silver paste with solid content higher than 70% have the double functions of cathodic protection and physical shielding in the paint, and corrosion resistance of a paint film is greatly improved. The prepared heavy-duty paint is novel carbon titanium cage water-based paint, has excellent corrosion resistance and strong adhesive force, and can be used alone or in combinationwith other intermediate paint and primer.

Description

technical field [0001] The invention relates to the field of heavy-duty anti-corrosion coatings, in particular to a metal flake-type one-component water-based heavy-duty anti-corrosion coating with dual anti-corrosion approaches and a preparation method thereof. Background technique [0002] Heavy-duty anti-corrosion coatings are used in harsh environmental conditions and are mostly used in marine and chemical industries, which have extremely high requirements on corrosion performance. They have two main features: long-term effect and thick film. Heavy-duty anti-corrosion coatings generally require multi-layer construction, including primers, intermediate paints and topcoats. At present, the application of traditional heavy-duty anti-corrosion coatings in production is mainly organic solvent-based heavy-duty anti-corrosion coatings. In terms of anti-rust pigments and fillers, traditional talcum powder, titanium dioxide and other non-metallic fillers have only a single anti-...
