Elastomer gel water-in-water colorful system paint

Abstract

The invention discloses an elastomer gel water-in-water colorful system paint which is formed by mixing a dispersed phase with a continuous phase, and the elastomer gel water-in-water colorful system painting is characterized in that: the dispersed phase consists of protective glue solution and elastic paint, the protective glue solution contains cation protective glue and is quaternary ammonium salt polysaccharide polymer with low grafting degree; the continuous phase contains gels which is anion polysaccharide cellulose ether; the weight ratio of the dispersed phase and the continuous phase is 1:1-2. When the cation protective glue in the dispersed phase meets the gels in the continuous phase, the cations and the anions can be bonded mutually; and simultaneously, the long-chain quaternary ammonium salt can form complex with acidic polysaccharide, chemical crosslinking occurs among active groups, so that the hardness of the paint can be adjusted, the stability is good, and the proportion of color grains can reach 40-50 percent.

Description

technical field [0001] The invention relates to a water-in-water multicolor paint, which belongs to the technical field of paint formula and preparation, and in particular to an elastomer gel water-in-water multicolor system paint. Background technique [0002] Liquid imitation granite paint is a kind of colloid, which contains a dispersed phase and a continuous phase. In the dispersed phase, there is a protective colloid solution, which makes the surface tension different, so that the two are incompatible with each other. This kind of paint is sprayed through a spray gun and has a colorful effect. After the decoration is completed, the particle pattern blooms naturally like granite. [0003] Liquid imitation granite paint was originally a kind of paint commonly known as "oil-in-water". However, due to the shortcomings of its production process, such as polluting the environment, low stability, low weather resistance and stain resistance, it leads to high production costs an...

Problems solved by technology

[0005] At present, "water-in-water" coatings on the market are mainly divided into two systems according to the hardness, soft particles and hard particles. Soft particles are suitable for large patterns. During the spraying process, the color particles bloom naturally, the borders of the patterns are slightly blurred, and the paint film is smooth and natural. But this system is not suitable for small patterns; the hard particle system is suitable for small patterns, the border of the pattern is clear, and the paint film has a concave-convex feeling, but when this system is used to produce large patterns, the granulation process is difficult to control, and the overall effect is more like terrazzo than terrazzo. Marble and granite, poor adhesion, unnatural patterns

That is to say, this kind of system has high selectivity to emulsion, strong pertinence, and is not widely used. Soft particles usually only correspond to large patterns, and hard particles usually only correspond to small patterns.

In the existing technology, the adjustment of the particle hardness and size of the coating system requires experimental adjustment of the combination of protective glue, gelling agent an
