Embodiment 1

[0025] Preparation of a kind of high hardness and abrasion resistance waterborne wood lacquer:

[0026] (1), preparation of nano-alumina slurry:

[0027] Directly adding nano-alumina powder into the wood lacquer system is not easy to disperse, because the stable nano-alumina slurry is prepared in advance, and then added to the wood lacquer system during the let-down stage.

[0028] a. Nano-alumina slurry is prepared from the following raw materials by weight: nano-alumina powder: 10, defoamer: 0.2, wetting agent: 0.2, stearic acid 0.5, aluminate 1.1, pH value adjustment Agent: 0.1, thickener: 0.4, deionized water: 87.5;

[0029] b. Preparation method: Add deionized water, defoamer, wetting agent, dispersant stearic acid and aluminate, and pH regulator in sequence in the stirring state of the disperser. After adding, disperse at a medium-low speed 5-10 minutes, then add nano-alumina powder, increase the speed to medium-high speed, then slowly add thickener, disperse at high s...

Embodiment 2

[0036] Preparation of a wood primer with high hardness and fullness for home decoration:

[0037] Step (1) is with embodiment 1.

[0038] (2), preparation of wood primer:

[0039] a. Water-based wood paint is prepared from the following raw materials by weight: water-based polyurethane dispersion: 500, acrylic emulsion 345, nano-alumina paste: 100, defoamer: 2, wetting agent: 5, pH adjustment Agent: 1. Coating agent: 14. Leveling agent: 4. Thickener: 4. Slip agent: 3. Deionized water: 20;

[0040] b. Preparation method: Add water-based polyurethane dispersion, acrylic emulsion, defoamer, wetting agent, and pH value regulator in order by weight in the stirring state of the disperser, disperse at a low speed for 5 minutes, and then slowly add nano-alumina slurry , disperse at medium speed for 20-30 minutes, defoam at low speed for 5-10 minutes, then add film-forming aids, leveling agents, thickeners, slip agents and deionized water in sequence, stir at medium speed for 5-15 mi...

Embodiment 3

[0042] Preparation of a wood primer with high hardness and fullness for furniture:

[0043] Step (1) is with embodiment 1.

[0044] (2), preparation of wood primer:

[0045] a. Water-based wood lacquer is prepared from the following raw materials by weight: water-based polyurethane dispersion: 845, nano-alumina paste: 100, defoamer: 2, wetting agent: 5, pH regulator: 1, Coating agent: 14, leveling agent: 3, thickener: 4, slip agent: 4, deionized water: 20;

[0046]b. Preparation method: Add water-based polyurethane dispersion, defoamer, wetting agent, and pH value regulator in sequence according to the weight of the disperser, disperse at low speed for 5 minutes, and then slowly add nano-alumina slurry, medium speed Disperse for 20-30 minutes, defoam at low speed for 5-10 minutes, then add film-forming aids, leveling agents, thickeners, slip agents and deionized water in sequence, stir at medium speed for 5-15 minutes, and filter out.

Abstract

The invention discloses high-hardness and wear-resistance aqueous wood lacquer and a preparation method thereof. The wood lacquer is prepared from the following raw material in part by weight: 500 to 850 parts of aqueous polyurethane dispersion, 0 to 350 parts of acrylic acid emulsion, 90 to 110 parts of nano aluminum oxide slurry, 2 to 5 parts of defoaming agent, 4 to 6 parts of wetting agent, 1 to 2 parts of pH regulator, 13 to 15 parts of film-forming assistant, 3 to 5 parts of leveling agent, 3 to 5 parts of thickener, 2 to 4 parts of slipping agent and 15 to 25 parts of deionized water. Because the nano aluminum oxide additive is added into the aqueous wood lacquer system, the hardness and wear resistance of the aqueous wood lacquer are improved; and the aqueous wood lacquer is environmentally-friendly, stable in performance and suitable for home decoration and furniture industry.

Description

technical field [0001] The invention relates to the technical field of water-based wood lacquer, in particular to a water-based wood varnish with high hardness and wear resistance and a preparation method thereof. Background technique [0002] With the increasing awareness of environmental protection, the use of solvent-based coatings has been increasingly limited, and water-based coatings have the advantages of no environmental pollution, low toxicity and no fire hazards, and more and more people's attention and attention. In developed countries such as Europe and the United States, with the deepening of environmental protection regulations, the sales of solvent-based wood lacquers are decreasing year by year, and the consumption of water-based wood lacquers is increasing year by year. In our country, with the deepening of reform and opening up, the rapid development of the national economy and the improvement of people's living standards, low-pollution and high-performance...
