[0021] The invention discloses a method for preparing a water-based multicolor paint, which can be realized by appropriately improving process parameters for reference by those skilled in the art. In particular, it should be pointed out that all similar substitutions and modifications are obvious to those skilled in the art, and they are all considered to be included in the present invention. The method and application of the present invention have been described through preferred embodiments, and the relevant personnel can obviously make changes or appropriate changes and combinations to the method and application described herein without departing from the content, spirit and scope of the present invention to realize 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 in conjunction with specific embodiments.

Embodiment 1

[0024] (1) Preparation of protective glue A Prepare the protective glue A solution and set it aside;

[0025](2) Color matching According to the desired pattern, add the white base paint B with a titanium dioxide content of less than 10% to the white base paint B solution with various color pastes to obtain a color base paint with a good color, according to the color The white base paint B of suitable titanium dioxide content can be selected for depth, as preferred, the present embodiment selects titanium dioxide content as the base paint latex paint of 10% and does not contain titanium dioxide and only contains the 0% base paint latex paint of filler to mix final To obtain a white base paint B with a titanium dioxide content of 5%, the mass fraction of the color paste in the final color base paint is no more than 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±5KU 10KU, add the color b...

Embodiment 2

[0050] (1) Preparation of protective glue A Prepare the protective glue A solution and set it aside;

[0051] (2) Color matching According to the desired pattern, add the white base paint B solution with a titanium dioxide content of less than 10% to the white base paint B solution with various color pastes (iron black, iron red and iron yellow) The color base paint of 5 colors of dark red, light red, dark gray, light gray, and light white can be obtained by toning, and the white base paint B with suitable titanium dioxide content can be selected according to the depth of the color. As a preference, all titanium dioxide is selected in this embodiment. For the white base paint B with 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...

Abstract

The invention belongs to the technical field of water-based coatings, and discloses a preparation method of a water-based multicolor paint. The method comprises the following steps: adding color pastes of various colors into a white base paint B solution containing titanium dioxide to obtain a colored base paint, adding the colored base paint into a transparent dispersion phase C, uniformly stirring to obtain a colored paint dispersion phase, adding the colored paint dispersion phase into a protective glue A solution, and granulating to obtain a finished product of the water-based multicolor paint. The mass fraction of titanium dioxide in the white base paint B is within 10%, and the mass fraction of color paste in the colored base paint does not exceed 20%. The viscosity of the dispersion phase of each color of basic color paint prepared by the method is basically consistent, the granulation particle size is controllable, and conditions are created for the stability of batches during large-scale production in a workshop.

Description

technical field [0001] The invention relates to the technical field of water-based paints, in particular to a preparation method of water-based colorful paints. Background technique [0002] Water-in-water multi-color paint is a series of products of water-based environmental protection paint system, also known as liquid stone, which was born to meet the continuous development of today's building exterior wall paint market. It is made of high-tech modified resin and stable pigments. It is fully water-based and one-time spraying colorful granite paint. The color produced is more realistic and durable. According to the granite samples provided by the designer, the degree of simulation It can reach 99%, and it is the best product to replace the granite of the exterior wall. The production process of water-in-water multi-color paint, which is more popular in the market now, is basically divided into three steps: 1. Produce the dispersed phase of the base paint; 2. Color the col...
