Problems solved by technology

[0005] Based on the wide application and excellent physical and chemical properties of two-component epoxy coatings, two-component epoxy coatings have been widely used. There are many reports on the research of two-component epoxy coatings, but the But the research of lacquer coating is rarely reported, and the main reason is that the coloring difficulty of epoxy primer coating, the anti-ultraviolet agent is difficult to be compatible with component material, and the adhesion ability of material is weak, for existing technology deficiency, so far there is no one implement an effective solution

Abstract

The invention provides a double-component water-dispersed epoxy primer coating and a preparation method thereof. The epoxy primer coating is composed of an A component and a B component, wherein the mass ratio of the A component to B component is 100:12-14, the A component is prepared from 50-52% of epoxy emulsion, 1.1-1.5% of wear-resistant agent, 0.5-0.8% of de-foaming agent, 0.2-0.4% of graphene dispersing agent, 0.2-0.4% of titanium-chrome yellow, 1.1-1.2% of coalescing agent, 0.5-0.8% of wetting agent, 1-1.5% of nanometer titania, 1.1-1.2% of sterilizing agent, 0.02-0.04 % of prussian blue and balance deionized water; the B component is prepared from 26-28% of curing agent and balance deionized water. The double-component water-dispersed epoxy primer coating and the preparation methodthereof have the advantages that the obtained epoxy primer coating not only has high ultraviolet decomposition resistance performance and high adhesive force, but also has simple technology method, low technology cost, and is suitable for large-scale industrial production.

Description

technical field [0001] The invention relates to the preparation of wood epoxy primer paint, in particular to a two-component water-dispersible epoxy primer paint and a preparation method thereof. Background technique [0002] Paint is coated on the surface of the object to be protected or decorated, and can form a continuous film firmly attached to the object to be coated, usually based on resin, or oil, or emulsion, with or without adding pigments, fillers, and adding corresponding Additives, viscous liquids prepared with organic solvents or water. Coatings belong to organic chemical polymer materials, and the formed coating film belongs to the type of polymer compounds. According to the classification of modern chemical products, coatings belong to fine chemical products. Modern coatings are gradually becoming a class of multifunctional engineering materials and an important industry in the chemical industry. There are four main functions of coatings: protection, decora...
