[0021] The invention discloses a preparation method of a water-based colorful paint, and those skilled in the art can learn from the content of this article and appropriately improve the process parameters to achieve. It should be particularly pointed out that all similar substitutions and modifications will be apparent to those skilled in the art, and are deemed to be included in the present invention. The method and application of the present invention have been described through the preferred embodiments, and it is obvious that relevant persons can make changes or appropriate changes and combinations of the methods and applications described herein without departing from the content, spirit and scope of the present invention to achieve and Apply the technology of the present invention.

[0022] In order to enable those skilled in the art to better understand the present invention, the present invention will be further described in detail below with reference to specific emb...

Embodiment 1

[0024] (1) Prepare protective glue A Prepare protective glue A solution and set it aside for use;

[0025](2) Toning According to the required pattern, add the white base paint B with titanium dioxide content within 10%, and add the color pastes of various colors to the white base paint B solution for toning to obtain the color base paint that has been adjusted according to the color. A white base paint B with a suitable titanium dioxide content can be selected for the depth. As a preference, in this example, a base paint latex paint with a titanium dioxide content of 10% and a base paint latex paint containing no titanium dioxide and only 0% filler are selected to mix the final A white base paint B with a titanium dioxide content of 5% is obtained, the mass fraction of the color paste in the final color base paint does not exceed 7%, the viscosity of the color base paint is adjusted to 110±5KU, and the viscosity of the transparent dispersed phase C is adjusted to 125± 10KU, a...

Embodiment 2

[0050] (1) Prepare protective glue A Prepare protective glue A solution and set it aside for use;

[0051] (2) Toning According to the desired pattern, add the white base paint B solution with a titanium dioxide content of less than 10%, and use various color pastes (iron black, iron red and iron yellow) to add the white base paint B solution to the solution. The color base paint of 5 colors of dark red, light red, dark gray, light gray and light white is obtained by color matching. According to the color depth, a white base paint B with a suitable titanium dioxide content can be selected. White base paint B with a white powder content of 8%, the mass fraction of color paste in the final color base paint is not more than 3%, the viscosity of the color base paint can be easily adjusted to 110±5KU, and the viscosity of the transparent dispersed phase C is adjusted to 125±10KU, add 5 colored base paints into the transparent disperse phase C and stir for 5-10 minutes to obtain 5 c...

Abstract

The invention belongs to the technical field of water-based paint, and discloses a preparation method of water-based colorful paint. The method is to add various color pastes into the white base paint B solution containing titanium dioxide to obtain a colored base paint, add the colored base paint to the transparent dispersed phase C and stir evenly to obtain a dispersed phase of the colored paint, and add the dispersed phase of the colored paint to the protective glue A The finished water-based colorful paint is obtained by granulating in the solution; wherein, the mass fraction of titanium dioxide in the white base paint B is within 10%, and the mass fraction of the color paste in the color base paint is not more than 20%. The viscosities of the dispersed phases of the basic paints of various colors prepared by the method are basically the same, and the particle size of the granulation is controllable, which creates conditions for the stability between batches during mass production in the workshop.

Description

technical field [0001] The invention relates to the technical field of water-based paints, in particular to a preparation method of a water-based colorful paint. Background technique [0002] Water-in-water colorful paint is a series of water-based environmentally friendly paint systems, also known as liquid stone, which was born to meet today's ever-developing architectural exterior paint market. It is made of high-tech researched and developed modified resins and pigments with good stability. It is an all-water-based, one-time sprayed colorful granite coating, which produces more realistic and durable colors. According to the granite samples provided by the designer, the degree of simulation is Up to 99%, it is the best product to replace granite for exterior wall. The more popular water-in-water colorful paint production process on the market today is basically divided into three steps: 1. Produce the dispersed phase of the base paint; 2. Color tones directly according t...
