Embodiment 1

[0030] A kind of high hardness wear-resistant anti-scratch one-component self-drying water-based wood varnish of the present invention comprises the following components by mass percentage:

[0031]

[0032] The water-based acrylic dispersion is Alberdingk AC2742, which is a pure acrylic dispersion emulsion with multiphase self-crosslinking, with higher TG, finer particle size than traditional core-shell dispersions, high fullness, and osmotic wettability. Good resistance, excellent film hardness, anti-stick, anti-scratch, anti-yellowing, stain resistance and chemical resistance.

[0033] The waterborne polyurethane dispersion is Bayhydrol UH 2593 / 1, which is a fatty acid modified anionic aliphatic polyurethane dispersion, which has excellent wet film transparency, high hardness and excellent scratch resistance.

[0034] Described environment-friendly solvent is the mixture of dipropylene glycol methyl ether and dipropylene glycol butyl ether, and the mass ratio of describe...

Embodiment 2

[0048] A kind of high hardness wear-resistant anti-scratch one-component self-drying water-based wood varnish of the present invention comprises the following components by mass percentage:

[0049]

[0050]

[0051] A method for preparing a high-hardness, wear-resistant and scratch-resistant one-component self-drying water-based wood varnish of the present invention comprises the following steps:

[0052] (1) Take each component according to the described components, and stir the water-based acrylic dispersion and the water-based polyurethane dispersion for 5 min at a speed of 500 r / min;

[0053] (2) Mix deionized water and pH regulator Amp95 at a ratio of 5:1, then add it to the stock preparation pot and stir for 5 minutes, then add the mixture of deionized water and environmentally friendly solvent to the stock preparation pot, and stir at a speed of 1000r / min for 10 minutes;

[0054] (3) Add defoamer, wetting agent, dispersant, matting powder, wax powder, leveling ag...

Embodiment 3

[0056] The difference between embodiment 3 and embodiment 1 is: a kind of high hardness wear-resistant anti-scratch one-component self-drying water-based wood paint of the present invention comprises the following components by mass percentage:

[0057]

[0058]

[0059] A method for preparing a high-hardness, wear-resistant and scratch-resistant single-component self-drying water-based wood paint of the present invention is characterized in that it comprises the following steps:

[0060] (1) Take each component according to the described components, and stir the water-based acrylic dispersion and the water-based polyurethane dispersion for 5 minutes at a speed of 560r / min;

[0061] (2) Mix deionized water and pH regulator Amp95 at a ratio of 5:1, then add it to the stock preparation pot and stir for 5 minutes, then add the mixture of deionized water and environmentally friendly solvent to the stock preparation pot, and stir at a speed of 800r / min for 10 minutes;

Abstract

The invention discloses a high-hardness, wear-resistant and anti-scratching single-component self-drying water-based wood paint and a preparation method for the same. The high-hardness, wear-resistantand anti-scratching single-component self-drying water-based wood paint is prepared from the following components in percentage by mass: 55 to 65 percent of water-based acrylic dispersion, 10 to 20 percent of water-based polyurethane dispersion, 3 to 5 percent of environment-friendly solvent, 0.3 to 0.5 percent of substrate wetting agent, 0.4 to 0.6 percent of antifoaming agent, 3 to 8 percent ofde-ionized water, 0.2 to 0.3 percent of dispersant, 0.8 to 1 percent of wax powder, 0.5 to 1 percent of extinction powder, 0.3 to 0.5 percent of leveling agent, 5 to 10 percent of silica sol, 0.5 to1 percent of water-based associated modified polyurethane thickener and 0.2 percent of pH conditioner. The high-hardness, wear-resistant and anti-scratching single-component self-drying water-based wood paint is low in VOC (volatile organic compound) and cost and high in wear resistance and anti-scratching performance.

Description

technical field [0001] The invention relates to the technical field of coatings, in particular to a high-hardness, wear-resistant and scratch-resistant one-component self-drying water-based wood paint and a preparation method thereof. Background technique [0002] Water-based coatings have been a hot topic in recent years, especially in today's increasingly stringent environmental protection requirements, water-based coatings with low pollution have become the focus of the development of major coating factories. Therefore, in recent years, major coatings Enterprises have launched water-based wood paint. [0003] However, compared with traditional solvent-based wood lacquers, water-based wood lacquers are much more expensive than nitro-lacquers, harder than two-component polyester lacquers, and even more incomparable in terms of wear resistance and scratch resistance. Therefore, two-component polyester paint has always been used as the main product in the field of convention...
