Problems solved by technology

Although the traditional matting powder can achieve a matte effect, due to the complex structure of the water-based multi-color coating itself, it is more difficult to overcome the problems of water resistance, whitening and storage stability after adding the matting powder. At the same time, there are more harms to the human body. , such as silicosis

preparation example Construction

[0054] A kind of preparation method of the matte water-based multicolored coating that does not need covering, comprises the following steps:

[0055] Stir 0.5-2 parts of thickener ASE-60 and water in equal proportions and add it to 20-50 parts of the continuous phase. After stirring again, add 30-70 parts of color dots and stir evenly to obtain a non-coating Matte water-based multicolor paint.

[0056] The preparation method of the colored dots is as follows: adding 200-500 parts of the colored base paint into 100-300 parts of the colloidal solution, then performing point cutting, and screening according to particle shape requirements to obtain the colored dots. The way of adding the color base paint is one of adding at the same time and adding in batches; the way of cutting the point is one of vacuum filtration and shearing of the dispersing disc.

[0057] The preparation method of the colloidal solution: add 20-40 parts of lithium magnesium silicate while dispersing in 400...

[0075] A kind of preparation method of the matte water-based multicolored coating that does not need covering, comprises the following steps:

[0076] Stir 0.5 parts of thickener ASE-60 and water in equal proportions and add it to 50 parts of the continuous phase. After stirring again, add 30 parts of color dots and stir evenly to obtain a matte water-based multicolor paint without overcoating.

[0077] The preparation method of the color dots: add 200 parts of the color base paint to 100 parts of the colloidal solution at the same time, then carry out vacuum filtration to cut the points, and screen according to the shape requirements of the particles to obtain the color dots.

[0078] The preparation method of the colloidal solution: add 20 parts of lithium magnesium silicate while dispersing in 400 parts of water, and finally disperse at high speed for 30 minutes, fully dissolve until there are no particles at all, filter and stand for use.

Abstract

The invention relates to finish-coat-free matte water-based colored paint and a preparation method thereof and belongs to the field of building paint. According to the paint provided by the invention, styrene-acrylic emulsion, a phosphate type dispersant, cellulose, a colloidal solution and polyamide wax have a common effect so that color points are stable and the suspension property is high; COASOL and two types of silicone modified acrylic emulsion with obvious particle size difference, and the polyamide wax are used as continuous phases of multi-colored paint; compared with traditional finish-coat matte water-based multi-colored paint, matting powder does not need to be added into the multi-colored paint and matte finish-coat varnish does not need to be brushed, and the matting and vintage effects can also be realized; the finish-coat-free matte water-based colored paint has excellent water resistance, water white resistance and storage stability; the disadvantages of traditional finish-coat matte water-in-water multi-colored paint are successfully overcome; the finish-coat-free matte water-based colored paint is applicable to non-plane matte water-based water-in-water paint and finish-coat-free matte multi-colored paint and the like.

Description

technical field [0001] The invention relates to a matte water-based paint, in particular to a matte water-based multi-color paint without overcoating and a preparation method thereof, belonging to the field of architectural paints. Background technique [0002] Water-based colorful paint usually contains more than two colors of color particles, and the color patterns are also colorful and diverse, so the water-in-water colorful exterior wall is a rising star of the real stone texture exterior wall paint, and it is more and more sought after by everyone. However, high-gloss coatings are irritating to human eyes, and people's vision is prone to fatigue for a long time, while matte coatings are soft in color and smooth in appearance, which can cover up the surface defects of the coating to a certain extent and overcome this defect of high-gloss materials. Meet people's aesthetic needs. People's pursuit of high-quality life makes matte water-based materials more and more demand...
