Example Embodiment

[0028] Example 1

[0029] Water-based acrylic wood coatings, including the following components by weight: 41 parts of water-based pure acrylic emulsion, 24 parts of starch emulsion, 2 parts of dipropylene glycol methyl ether, 1 part of silicone leveling agent, and associative polyurethane thickener 1.2 Parts, 2.4 parts of calcium naphthenate, 15 parts of water, 4.2 parts of tributyl phosphate, 0.1 parts of casson, 9 parts of filler diatomaceous earth, 0.7 parts of sodium polyacrylate.

[0030] The preparation method of the wood coating is:

[0031] (1) Add sweet potato starch, potato starch, and purple potato starch with a mass ratio of 3:3:1 to a phosphoric acid solution with a mass concentration of 3%. The total weight of sweet potato starch, potato starch, and purple potato starch is compared to the weight of the phosphoric acid solution. The ratio is 1:3. Stir the starch solution evenly in a slurry state, transfer it to a constant temperature water bath, heat it to 50°C and sti...

Abstract

The invention provides a waterborne acrylic wood coating. The waterborne acrylic wood coating comprises, by weight, 40-45 parts of acrylic emulsion, 20-25 parts of starch emulsion, 2-4 parts of coalescing agent, 0.5-1 part of leveling agent, 1-1.5 parts of thickener, 2-3 parts of drier, 15-20 parts of water, 4-5 parts of fire retardant, 0.1-0.2 part of mildew-proof agent, 9-14 parts of filler and 0.5-1 part of sodium polyacrylate. The invention further provides a preparation method of the waterborne acrylic wood coating. The waterborne acrylic wood coating is high in adhesive force and capable of purifying air effectively.

Description

technical field [0001] The invention relates to a coating, in particular to a water-based acrylic wood coating and a preparation method thereof. Background technique [0002] Water-based wood coatings are water-based wood coatings that use water as the main solvent or can be diluted with water. They can be called water-based wood coatings. They have the same or similar functions as solvent-based wood coatings. They mainly protect and decorate wood. Water-based wood coatings The biggest difference between paints and solvent-based wood coatings is that they can be diluted with water. Due to the large amount of VOC (organic solvents) in solvent-based wood coatings, they participate in the oxidation reaction to form ozone under the action of sunlight and heat, resulting in poor air quality and summer smog, which is harmful to the earth's organisms. At the same time, VOC also causes great harm to the human body, mainly in the following ways: one is that the smell stimulates the ...
