Abstract

The invention discloses a composite multi-functional two-component aqueous wood white top coat, which comprises a component A, a component B and water according to a mass part ratio of 100:20-25:10-20, wherein the component A is prepared from the following raw materials by mass: an aqueous hydroxy acrylic acid resin, a compound modified self-cross-linking acrylic acid polymer, an aqueous titanium white slurry, an aqueous matting agent, a defoamer, a wetting agent, a thickening agent, a dispersant, a leveling agent, an anti-mildew bactericidal agent, and the balance of water, and the component B is prepared from the following raw materials by mass: hydrophilic aliphatic polyisocyanate and propylene glycol methyl ether acetic acid ester. The composite multi-functional two-component aqueous wood white top coat of the present invention has advantages of good antibacterial effect, good aldehyde removing effect, good stain resistance, environmental protection, good hardness, high fullness, and moderate cost.

Description

technical field [0001] The invention belongs to the technical field of two-component waterborne woodware coatings, in particular to a composite multifunctional two-component waterborne woodware white topcoat and a preparation method thereof. Background technique [0002] As a decorative material, wood coatings have higher and higher decorative requirements and environmental protection performance. As wood decorative materials, traditional two-component solvent-based PU wood coatings have mature product formulations and processes, and product performance can also be satisfied. The higher demand is mainly manifested in good fullness, high hardness, up to 2H-3H, good high temperature and alcohol resistance, and not easy to tarnish, but because it contains a large amount of volatile organic compounds (VOC), it is harmful to air pollution and The health of construction workers will bring certain harm, and it is more and more obvious that they are restricted by relevant national e...
