Abstract

The invention belongs to the technical field of water-based wood ware paint, and particularly relates to a water-based wood stain-resistant white finish paint and a preparation method thereof. The water-based wood stain-resistant white finish paint includes a main paint A and a curing agent B; the main paint A includes: water-based acrylic acid Emulsion, 48‑60wt%, coalescent, 4‑8wt%, water-based additive, 1.3‑5.8wt%, titanium dioxide, 18‑24wt%, matting powder, 0.3‑1.2wt%, water, 1.0‑28.4wt% %; Curing agent B is a sulfonate hydrophilic modified HDI trimer. On the basis of maintaining its excellent hardness, scratch resistance and adhesion, the water-based stain-resistant white finish paint for woodware of the present invention has good resistance and tolerance to different stains, especially for red wine, mustard, coffee, alkali stains, etc. Has obvious anti-fouling effect.

Description

technical field [0001] The invention belongs to the technical field of water-based woodware paint, in particular to a water-based stain-resistant white finish paint for woodware and a preparation method thereof. Background technique [0002] Furniture is a necessary article for people's daily life and work. It is not only a practical product, but also an ornament to beautify the environment and give people aesthetic enjoyment. China is a big country in the production and export of furniture, and the total demand for furniture coatings is quite large; in 2018, the output of wood coatings in my country was more than 1.4 million tons, accounting for about 7% of the total output of coatings. increase. my country is a big exporter of furniture, and exported furniture has high requirements for environmental protection, which requires furniture manufacturers to use water-based wood coatings. With the improvement of people's awareness of environmental protection and home safety and...
