Abstract

The invention discloses water-based single-component primer-topcoat paint and a preparation method thereof and relates to the technical field of anti-corrosion coatings. The water-based single-component primer-topcoat paint is prepared by mixing and stirring the following components in parts by weight: 400-600 parts of a water-based epoxy resin-modified acrylic emulsion, 1-3 parts of a pH modifier, 30-80 parts of an environment-friendly cosolvent, 5-20 parts of a dispersing agent, 0.5-3 parts of an antifoaming agent, 2-3 parts of a flatting agent, 3-5 parts of a base material wetting agent, 5-20 parts of a flash-rust inhibitor, 10-20 parts of a thickener, 20-40 parts of an anti-settling agent, 50 parts of a pigment, 70-150 parts of a rust protection filler and 150-250 parts of deionized water. The water-based single-component primer-topcoat paint has the characteristics of being high in drying speed, high in anticorrosion property, low in VOC (volatile organic compound), simple in construction and operation and high in one-time film-forming property.

Description

technical field [0001] The invention relates to the field of anti-corrosion coatings, in particular to a water-based one-component bottom-surface-in-one paint and a preparation method thereof. Background technique [0002] Today, there are mainly two types of traditional anti-corrosion coating systems in China, which are primer + primer + top coat composite anti-corrosion coating system or primer + top coat composite anti-corrosion coating system. Among them, the primer mainly protects the surface of the substrate, and at the same time provides good adhesion and anti-corrosion performance; the primer mainly plays the role of repairing and filling, making the surface of the substrate smooth, which is beneficial to the topcoat coating, and the topcoat is mainly used for decoration. Protective effect, with high hardness, high wear resistance, high chemical properties and so on. However, these two kinds of coating processes are complicated, and the construction period is long, ...
