Problems solved by technology

The production mechanism of protective glue is roughly the same. Most water-based colorful paints use protective glue with trade names of RD, RDS, GTS, and VS-15, but the difference in subsequent processing methods makes the performance of the protective glue quite different; and the application of cellulose There are many varieties, and the variety and quality of the emulsion are also uneven, which causes the protective glue in the existing water-in-water colorful paint to be easily affected by factors such as ambient temperature. The water-based colorful paint system is unstable, and the following problems exist: 1. The particles are easy to shrink, Bleeding; 2. The paint is easy to settle and delaminate; 3. The paint film is easy to turn white when it meets water; 4. The water resistance of the paint film is poor
In order to solve these problems, the patent CN103952051A discloses a preparation method of internal cross-linking water-based colorful coatings, and its technical scheme is to reduce the cross-linking reaction speed by adding an organically modified gelling agent to the dispersed phase containing polysaccharides, so that The cross-linking agent can be evenly dispersed in the dispersed phase, and gradually cross-link the gel in the later stage, so that the color particles are cross-linked as a whole, which greatly improves the strength and protection range of the gel, thereby ensuring the stability of the colorful paint and expanding the application range; However, the inventors of the present application have found that this chemical crosslinking method requires the use of expensive organically modified gel agents to carry out crosslinking reactions and control the gel speed. At the same time, chemical crosslinking gels are irreversible, which makes internal crosslinking The preparation technology of multi-color paint is limited

Abstract

The invention discloses high-performance colorful paint. The high-performance colorful paint is prepared through adding component A colored particles, with different colors and shapes, shaped in the component C into the component B. The colored particles of the component A are prepared from water, protective colloid, a thickener A, a wetting agent, a dispersant, a pigment, a filler, a defoaming agent, a pH adjusting agent, an elastic pure acrylic emulsion and surface organic modified cellulose ether. The component B is prepared from water, a silicone acrylic emulsion, a film-forming aid, a bactericide, a thickener B and a silane coupling agent. The component C is prepared from water and protective colloid. The protective colloid is subjected to surface organic treatment. The component A colored particles, with different colors and shapes, shaped in the component C and the component B are uniformly stirred so that the high-performance colorful paint is obtained. The invention also discloses a preparation method of the high-performance colorful paint. The high-performance colorful paint has high strength and can be applied through spray-coating.
