and S03, adding the color point dispersion liquid into the continuous phase and carrying out second mixing treatment to obtain the sand-in-water multicolor paint.
According to the preparation method of the sand-in-water multicolor paint provided by the embodiment of the application, the base paint is added into the protective glue solution for first mixing treatment, so that one or more base paints with well-mixed colors are granulated in the protective glue solution; and then, adding the color point dispersion liquid into the continuous phase to mix the color points into the continuous phase, thereby obtaining the sand-in-water multicolor paint capable of forming a film on the substrate. The method promotes the color points to be uniformly dispersed in the paint system, ensures that the paint has good stability, is simple and convenient to operate, and is suitable for large-scale preparation of the sand-in-water multicolor paint.
The compositions and effects of the protective glue solution, the base paint and the continuous phase in step S01 are as described above, and are not repeated herein for brevity.
In step S02, the base paint is added to the protective glue solution and subjected to a first mixing process, so that one or more base paints with well-adjusted colors are granulated in the protective glue solution to obtain color dots with a particle size range meeting the requirement, and the color dots can be independently flaky or particulate in the protective glue solution and are incompatible with each other.
The specific operation of adding the base paint into the protective colloid solution and performing the first mixing treatment may refer to the conventional technique in the art, for example, dispersing the base paint into the protective colloid solution in a stirring device so that the color points are mutually incompatible and can be obtained with proper particle size.
In step S03, the color dot dispersion is added to the continuous phase and a second mixing process is performed to mix the color dots in the continuous phase to obtain a sand-in-water multicolor paint that can be formed on the substrate, and the sand-in-water multicolor paint forms a continuous protective film on the substrate to protect the color dots.
The specific operation of adding the color point dispersion liquid into the continuous phase and performing the second mixing treatment can refer to the conventional technology in the field, for example, adding the color point dispersion liquid into the continuous phase under a high-speed stirring state, so that the color points are uniformly dispersed in the continuous phase, and each color point is independent in a sheet shape or a particle shape in the continuous phase and is not compatible with each other.
Further, after the step of adding the color point dispersion to the continuous phase and performing the second mixing treatment, the viscosity of the paint may be adjusted by adding a small amount of a thickener.
