Water-in-water colorful stone simulated paint

Abstract

The invention provides a novel water-in-water colorful stone simulated paint, and belongs to the technical field of coating preparation. In the process of preparing a dispersion phase, a surface treated calcium carbonate is added, and the dispersion phase prepared from the calcium carbonate can be obviously separated from the aqueous phase; the protective glue component mainly consists of cellulose, water, water-soluble resin, defoaming agent, dispersant and preservative; by adding the protective glue component, the dispersion phase is coated by the protective glue, so that the prepared colorful paint has good stability and the dispersion phase is obviously separated from the dispersion medium; and the aqueous dispersion medium mainly consists of water, organic bentonite, aluminum sulfate and magnesium chloride. On the process design, secondary reaction of base paints is adopted to improve the viscosity of the base paints and the strength of cohesion; and on the formula design, protective solution with polarity is added among the base paints of different colors, and granules are uniformly distributed in the protective solution under mechanical action.

Description

technical field [0001] The invention relates to a building paint or a paint for interior and exterior walls, in particular to a water-in-water type black color imitation stone paint. Background technique [0002] With the improvement of living standards, people's pursuit of life is not only to solve the problem of food and clothing, but to the pursuit of spirit and materials. At the same time, people gradually begin to reflect simple and individual styles in the decoration of interior and exterior walls. The construction of Xuancai paint is relatively simple, and it can meet the needs of consumers in terms of product individuation and diversification, so it has gradually attracted people's attention. [0003] In the 1980s, Xuancai paint was popular in my country, but because it contained organic solvents such as toluene and xylene, a large amount of toxic organic solvents would be released during production and construction, which constituted a threat to the environment and ...

AI Technical Summary

Problems solved by technology

[0006] At present, there are a small amount of water-in-water type Xuancai paint products for sale in the market, but the storage stability is generally poor. After a period of storage, the patterned particles will sink, and there will be a layer of protective glue on it. The solution is in a turbid state, obviously showing the same color as the patterned color grains

And the cohesive force of the patterned particles is not enough, after a period of storage, the patterned particles are easy to become broken, so that the sprayed Xuancai paint has a great change

Therefore, it is urgent to study a new type of water-in-water type Xuancai coating to solve the common problems of poor storage stability and poor cohesion of patterned particles.
