Abstract

The invention relates to the technical field of coatings, and particularly discloses waterborne epoxy primer and a preparation method thereof. The waterborne epoxy primer comprises a component A and acomponent B, wherein the component A comprises ingredients in percentage by mass as follows: a waterborne epoxy emulsion, a waterborne epoxy acrylic emulsion, a defoaming agent, a dispersing agent, pigment and filler, a base material wetting agent, anti-rust pigment, a thickening agent, an anti-rust auxiliary, an anti-settling agent and the balance deionized water; the component B comprises an amine curing agent and deionized water; a mass ratio of the component A to the component B in the waterborne epoxy primer is (4-6):1. The waterborne epoxy primer is good in gloss retention, good in saltfog resistance, good in stability and low in ingredient cost, has low construction difficulty and is excellent waterborne epoxy primer with good performance and low cost.

Description

technical field [0001] The invention relates to the technical field of coatings, in particular to a water-based epoxy primer and a preparation method thereof. Background technique [0002] Although traditional solvent-based two-component epoxy coatings have excellent properties such as low film-forming temperature, strong adhesion, good wear resistance, and high hardness, their high VOC content seriously pollutes the environment. The traditional oil-based paints are gradually being replaced by environmentally friendly paints, among which the environmentally friendly paints represented by water-based paints are an important part of modern green paints. Water-based paint is recognized by consumers for its characteristics of low VOC, energy saving, non-toxicity, and environmental protection. Due to its stability, salt spray resistance, and gloss retention, it is lower than traditional paints, and the construction is difficult and the cost of ingredients is high. The developmen...
