Problems solved by technology

In the prior art, there are also many patents or documents disclosing some two-component water-based wood coatings and their production methods, but the coating effects in these patents mostly only meet some basic physical performance indicators of environmental performance and paint film, and other special The additional functions are not very ideal, and the cost is high. In addition, most of these coatings do not have the characteristics of stain resistance and additional composite functions such as anti-mold and formaldehyde removal at the same time.

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 water-based woodware coatings, and in particular relates to a composite multifunctional two-component water-based woodware white finish 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 decoration materials, the traditional two-component solvent-based PU wood coatings have mature product formulas and processes, and the product performance can also meet The higher demand is mainly manifested in good fullness, high hardness, which can reach 2H-3H, high temperature resistance and alcohol resistance, and is 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 hazards, which are increasingly restricted by the relevant...
