preparation example Construction

[0064] The invention also discloses a preparation method of a water-based anti-scratch full-matte solid-color wood paint, comprising the following steps:

[0065] (1) Prepare raw materials: including 55-72% water-based polycarbon matte polyurethane dispersion, 3-8% water-based acrylic copolymer dispersion, 7-10% water, 1-1.5% cosolvent, 0.3- 0.8% defoamer, 10-25% water-based titanium dioxide paste, 0.2-1% leveling agent, 0.2-0.5% wetting agent, 0.3-0.8% hand feeling agent, 0.5-1.3% thickening agent and 0.7-5% water-based color paste.

[0066](2) Under normal temperature conditions, put the water-based acrylic copolymer dispersion in a conventional high-speed disperser according to the mass percentage, put in the mixed solution of co-solvent and water, dispersant and defoamer at medium speed, and stir at high speed for 20-30 minutes After that, the detection fineness is less than or equal to 25 microns.

[0067] (3) Under normal temperature conditions, put the water-based pol...

Embodiment 1

[0075] A water-based, scratch-resistant, full-matte solid wood coating consisting of:

[0076]

[0077] Prepare raw materials at normal temperature (note: normal temperature is 25°C), put water-based polycarbon matte polyurethane dispersion and water-based acrylic copolymer dispersion in a conventional high-speed disperser according to percentage, and put cosolvent and water at medium speed. After mixing liquid, defoamer, water-based titanium dioxide slurry, wetting agent, leveling agent, hand-feeling agent, thickening agent, and water-based color paste, stir for 20-30 minutes, and the fineness is less than or equal to 30 microns, and the pH is in 7.5-9, there is no shrinkage crater and other bad film effects by spraying. After hard drying, check the gloss, and take out the finished product after passing the test.

[0078] The present embodiment 1 obtains the results in the following table through comparison with conventional waterborne wood coating products and inspection:...

Abstract

The invention discloses a water-based anti-scratch full-dull solid-color wood coating and a preparation method thereof. The coating includes 55-72% water-based polycarbonate matte polyurethane dispersion, 3-8% water-based acrylic acid copolymer dispersion, 7-72% 10% water, 1-1.5% co-solvent, 0.3-0.8% defoamer, 10-25% water-based titanium dioxide paste, 0.2-1% leveling agent, 0.2-0.5% wetting agent, 0.3 ‑0.8% hand feel agent, 0.5‑1.3% thickener; by using the water-based polycarbonate matte polyurethane dispersion in the present invention, the full matte effect can be achieved without adding any matting additives, while maintaining the brilliance of the color, water-based acrylic The copolymer dispersion provides pigment encapsulation and avoids color fading during wiping. The addition of polyether modified silicone hand agent in the formula system can bring good scratch resistance and excellent slipperiness.

Description

technical field [0001] The invention relates to the technology in the field of coatings, in particular to a water-based anti-scratch full-matte solid-color woodware coating and a preparation method thereof. Background technique [0002] With the rapid development of my country's social economy, consumers have higher and higher requirements for the quality of life. In terms of wood decoration and furniture purchase, the demand for high-end solid wood furniture is much higher than that of panel furniture or wood-based panel furniture. [0003] Water-based wood paint is a polymer material that uses water instead of organic solvents in traditional oil-based paints as a dispersion medium. However, the water-based solid color wood paints on the market generally have a high gloss, or cannot maintain the vividness of the color and the scratch resistance of the surface when the gloss is extremely low. Therefore, the present invention provides a low-gloss, anti-scratch, high-color-br...
