The water-in-water multicolor paint is also called liquid stone. Commonly known in the industry as water-in-water multicolor paint. The aqueous multicolor paint is actually a dispersed aqueous phase of an aqueous latex paint, and is a multi-phase suspension of a continuous phase consisting of a protective glue solution.
Bentonite is also called montmorillonite, and its element is called "universal" clay. Generally, the color is white, gray, pink, yellow soil and other colors. The bentonite is divided into nano bentonite, calcium bentonite, hydrogen bentonite and organic bentonite according to the types of cations among the bentonite layers. Bentonite is a clay containing montmorillonite as main ingredient, the montmorillonite is layered aluminosilicate mineral, and has two (Si-Al) -O tetrahedral layers sandwiching one [ Al (Mg, Fe) - (O, OH)]Octahedral layer composition. The clay mineral with 3 layers is TOT type, is rich in crystal water, has negative charges between layers, and can adsorb Mg2+、Ca2+、Na+、k+And the like. The performance of bentonite is mainly determined by the type and content of montmorillonite contained in the bentonite, the bentonite has strong hygroscopicity, water swelling is easy to form thixotropic gel, a colloid suspension is dispersed in an aqueous medium, a concentrated dispersion system of the bentonite has the characteristic of typical shear thinning, and after the shearing action is stopped, the structure of the bentonite is gradually restored along with the prolonging of time due to the positive thixotropy of the system, so that the viscosity of the bentonite is increased. In addition, the material has huge surface area, so that the ion exchange capacity and the adsorption capacity are strong.
The montmorillonite mineral crystal structure is a layered silicate with cationic isomorphic substitution in the structural unit layers, such as Al3+Can replace Si in silicon-oxygen tetrahedron4+，Fe2+Or Mg2+Substitution of Al in aluminous octahedra3+Interlayer negative charges are generated. The negative charge of montmorillonite is mainly due to Mg2+A part of Al in substituted aluminoxy octahedron3+Generated and distributed between the layers, so that the montmorillonite unit cell acts like a "macroanion" that adsorbs cations. However, most of these negative charges are distributed on the surface of the layered silicate, and the negative charges in the aluminous octahedron are far from the cations adsorbed on the surface of the clay mineral, so that the weak cation binding force promotes the cation exchange. Cation exchange capacity is the most important feature of montmorillonite. Therefore, when the bentonite is dispersed in the paint, the polar groups-OH, -COOH, -CH of organic molecules such as polyvinyl alcohol, acrylic acid, polyvinyl acetate, hydroxyethyl cellulose, and carboxymethyl cellulose in the paint2CH2OH and the like are attracted by negative charges between montmorillonite layers in bentonite, and are further inserted into the layers to form a montmorillonite-organic molecule composite. The composite has an anti-settling effect in the coating, because montmorillonite and organic molecules are mutually crosslinked to form a uniformly distributed three-dimensional network structure, and the three-dimensional network can realize a good suspension effect. And organic molecules can enter between the montmorillonite layers, so that the consistency of the coating is increased. The montmorillonite organic composite has irreversible property, and can be dehydrated to obtain hydrophobic substance, so as to improve water resistance of coating film.
