Description

Background
In the sand-in-water coating, especially the litchi surface multicolor paint has higher requirements on the texture and the storage stability of color dots. However, most of strong-quality multi-color paints realize thickening of the paint through the strong association effect of the hydrophobic modified cellulose, the strong reaction type wetting agent and the protective glue, the strong quality of the existing litchi surface multi-color paint is realized by using the idea, but the color point size change of the same engineering construction in different time periods is obvious due to the color point heat storage shrinkage.
CN112940556A discloses a sand-in-water coating and a preparation method thereof, belonging to the technical field of sand-in-water coatings. The sand-in-water coating and the preparation method thereof are simple and reasonable, and the synthetic materials are mixed and stirred in sequence to obtain a finished product with good quality; the environment is protected, and the harm to the health of people is small; the paint has the advantages of good stability, good adhesiveness and film-forming property, difficult peeling, good water resistance and long service life. But that is still faced with the problem of poor heat storage stability of the color dots.
CN112662224A discloses a sand-in-water multicolor paint with high stability, which comprises a sand-containing base paint, a continuous phase emulsion and a second part of protective adhesive, wherein the sand-containing base paint comprises: a first part of protective gum, anionic surfactant, nonionic surfactant, filler, cellulose, emulsion, water and sand; the continuous phase emulsion comprises: an emulsion and water; the protective adhesive comprises: lithium magnesium silicate or modified lithium magnesium silicate, and water; the first part of protective glue and the second part of protective glue are both magnesium silicate or modified magnesium silicate aqueous solutions. Due to the adoption of the mixed surfactant, three colloids of the sand-containing base paint, the continuous phase emulsion and the second part of protective glue in the multicolor paint can interact more uniformly and orderly, and can exist in a finished product more stably; in addition, the surfactant can improve the selection tolerance of the sand-in-water multicolor paint in main raw materials such as protective glue, emulsion, cellulose and the like, and enhance the compatibility. But still faces the problem that the color point heat storage shrinkage causes the color point size of the same project to change obviously in different construction time periods.
In view of the above, there is an urgent need for litchi surface multicolor paint with strong texture and good color point heat storage stability.
