Waterborne two-component woodware coating and preparation method thereof

The invention discloses a waterborne two-component woodware coating and a preparation method thereof. The waterborne two-component woodware coating is prepared from main agent A and curing agent B. The main agent A comprises high-hydroxyl-value acrylic emulsion, low-hydroxyl-value acrylic emulsion, an aqueous polyurethane dispersion, a film forming auxiliary, a moistening agent, a leveling agent, an antifoaming agent, wax, extinction powder, a thickening agent, a preservative and deionized water, and the curing agent B comprises waterborne isocyanate and a solvent. The waterborne two-component woodware coating uses hydroxyl acrylic and the aqueous polyurethane dispersion as main film forming matters, the waterborne isocyanate serves as a cross-linking agent, the extinction powder and a wax auxiliary are added, curing reaction is performed at the normal temperature, and the coating has the advantages of high hardness, excellent chemical resistance, good scratch resistance, better transparence and simple, economical and reasonable production process, and can be widely applied to products such as wooden furniture and doors and windows.
