Problems solved by technology

However, the matte oils currently used in China are mainly oil-based systems, which contain a large amount of organic solvents, which will volatilize during production and construction, causing adverse effects on the health of construction workers. Therefore, the development of environmentally friendly water-based matte oils has become a research hotspot.

Embodiment 1

[0024] Add 40 parts (weight, the same below) of surface-modified silica matting powder into the mixing tank, 320 parts of polyacrylate soft emulsion with a glass transition temperature of -5°C, and 80 parts of polyacrylate soft emulsion with a glass transition temperature of 80°C. Polyacrylate hard emulsion, 4 parts of polyethylene wax powder, 120 parts of deionized water, 0.2 parts of wetting agent, 2 parts of anti-scratch agent, mix at low speed until the emulsion is fully infiltrated with matte powder, and then stir at high speed with a high-speed mixer For 60 minutes, the speed is 2000 rpm, and the matte powder is fully dispersed in the emulsion.

[0025] Pour the mixed material into the mixing tank, add 0.2 parts of defoamer, turn on the homogenizer of the mixing tank, stir and turn on the vacuum for 30 minutes to remove the air bubbles in the material due to high-speed stirring. Release the vacuum and pressurize the mixing tank with an air compressor, open the valve at t...

Embodiment 2

[0027] Adopt 55 parts of polyacrylate hard emulsions, 245 parts of polyacrylate soft emulsions as the connecting material, other formulas and processes are all the same as in Example 1, and compared with Example 1, the obtained water-based matte oil has lower film hardness. However, the film-forming performance is better, the surface drying time is short, and the coating film adheres better to the substrate.

Embodiment 3

[0029] Adopt 100 parts of polyacrylate hard emulsions, 300 parts of polyacrylate soft emulsions as the connecting material, other formulas and processes are all the same as in Example 1, the water-based matte oil obtained is compared with Example 1, and the surface drying time of the coating film is shorter Long, but better hardness and wear resistance.

Abstract

Disclosed is a watersoluble whose components and content of mass are:latex base material, wax powder 0.7-0.8%, water 20-25%, assistant 2-3%. Besides,the preparing method for the watersoluble is also disclosed. It is a watersoluble polyacrylate latex,with better hardness and flexibility,when it is coated on the paper surface,its wear resistance and film forming performance are all good,as well as hand feeling.

Description

technical field [0001] The invention relates to a water-based matte oil, and also relates to a preparation method of the water-based matte oil. Background technique [0002] Matte oil is a kind of low-gloss paint, which is widely used in developed countries such as the United States and Japan, and it has also been listed in my country for a long time. The paint film obtained by varnish decoration has a plump and thick appearance and a mirror-like luster. Matte is relative to bright light, the paint film has no strong luster, also called soft light. Gloss and matte have the same aesthetic feeling and have different decoration styles. The glossy paint film is smooth and glamorous, but sometimes people feel uncomfortable when there is too much strong light reflection in a certain environment. The matte paint film is very soft, giving people an elegant and comfortable feeling, and has a strong texture, which just caters to the current psychology of returning to simplicity and...
