Problems solved by technology

[0005] In recent years, a paint with the effect of imitating natural stone such as granite or marble has appeared. By spraying on the exterior wall, it can produce a simulated colorful pattern effect. However, most of this type of paint currently adopts a water-in-oil or oil-in-water structure. Inevitably produce harmful gas, and its curing speed is not ideal

Abstract

The present invention discloses an aqueous stone-like paint and a preparation method thereof. During preparation, a dispersing phase and a dispersing medium are respectively prepared; and then the dispersing phase with a single color is added to the dispersing medium to uniformly stir to obtain a one-component aqueous stone-like paint. The aqueous stone-like paint of the present invention has strong decoration, wherein a texture effect created by the aqueous stone-like paint with one spray coating is the same as a texture effect of the original stone, imitation degree exceeds 90%, and a color and patterns can be controlled. In addition, the aqueous stone-like paint of the present invention is widely used for cement base wall surfaces, coating materials, stucco, stone paints and other various foundation walls, and is especially suitable for external thermal insulation systems.

Description

technical field [0001] The invention relates to a paint for building, in particular to a paint with the effect of imitating natural stones such as granite or marble. Background technique [0002] Acrylic emulsions are widely used in the fields of construction and decoration, and can be classified according to their uses: emulsions for interior walls, emulsions for exterior walls, elastic emulsions, waterproof emulsions, sealing emulsions, etc. According to the composition of the product, it can be divided into pure acrylic emulsion, silicone acrylic emulsion, styrene acrylic emulsion, vinegar acrylic emulsion, etc. [0003] For example, pure acrylic emulsion uses acrylic acid copolymer emulsion as film-forming substance, styrene-acrylic emulsion uses copolymer emulsion of styrene and acrylic monomer as film-forming substance, and vinegar-acrylic emulsion uses copolymer emulsion of vinyl acetate and acrylic monomer as film-forming substance. Film-forming substances. [0004...
