Abstract

The invention discloses a nano-scale pure water-based metal anti-corrosion coating, which comprises the following components in parts by weight: 80-95 parts by weight of nano-scale water-based acrylic copolyester with narrow molecular weight distribution; 4-15 parts by weight of crosslinking agent solution; 0.5-2.5 parts by weight of guiding agent solution; 0.1-0.5 parts by weight of wetting agent; 0.1-0.5 parts by weight of leveling agent; 0.1-0.5 parts by weight of defoamer; 0.1-1.0 parts by weight of thickener; Zinc ammonium ion solution; the cross-linking guide solution is DL-serine solution; nanoscale water-based narrow molecular weight distribution acrylic copolyester achieves cross-linking through the interaction of zinc ions and DL-serine. The metal anti-corrosion coating of the present invention does not use any organic solvent, and still has excellent neutral salt spray resistance under the premise of significantly shortening the aging time of the metal anti-corrosion coating; it has the characteristics of self-drying at room temperature and very fast drying speed.

Description

technical field [0001] The invention belongs to the technical field of coatings, and in particular relates to a nanoscale pure water-based metal anti-corrosion coating and a preparation method and application thereof. Background technique [0002] In the prior art, coatings are usually solvent-based coatings and water-based coatings. Due to its high VOC content, as high as 420mg / L, solvent-based coatings cause environmental pollution and affect human health and gradually decrease. Due to its low VOC content, water-based coatings have been widely promoted. [0003] At present, the main materials for preparing water-based coatings on the market are more acrylic emulsions, polyurethane epoxy resin dispersions and alkyd resins. Among them, the acrylic emulsion is a one-component water-emulsion type waterproof coating obtained by adding a variety of additives to the acrylic polymer emulsion as the base material. Its structure is random copolymer particles, so 150mg / L of polar...
