Concrete Surface Coloring Composition

Abstract

A composition for coloring the surface of concrete, according to the present invention, comprises: 8 wt% of a coloring dye having a size of 0.01-1 nm; 45 wt% of a diluent formed by mixing ion exchange water and ethylene glycol in a ratio of 7:3 by weight; 7 wt% of methyl methacrylate; 0.06 wt% of polydimethylsiloxane; 0.5 wt% of a fluoropolymer; 6 wt% of colloidal silica; and 25 wt% a modified silicate. According to the present invention, the pH of a surface-colored part is 11-13, which is as alkaline as the concrete of an alkaline component having a hydroxyl group of Ca(OH)3, and a firm and beautiful concrete surface is completed since the coloring thereof is carried out by penetrating 2-3 mm. In addition, semi-permanent durability is provided to the surface of concrete while simultaneously enabling stable color expression, and there are no agglomeration of a preparation or no two colors, and no spots or development phenomena during coloring.

Description

technical field [0001] The present invention relates to a concrete surface coloring composition, in particular to a concrete surface coloring composition that can be penetrated and coated on the concrete surface during the concrete surface grinding process, so that it can not only endow the concrete surface with semi-permanent durability and realize stable color expression, but also Concrete surface coloring composition that does not cause coagulation of materials, or does not cause blotches or color development when different colors are colored, and expresses vivid colors. Background technique [0002] Usually, the factors that determine the strength of concrete are the ratio of water and cement, the amount of cement used, the ratio of admixture materials, and the size of the main material. However, it is impossible to meet the freeze-thaw resistance and durability requirements stipulated in the current concrete standards based on the above factors alone. Therefore, in ord...

Problems solved by technology

[0007] However, the disadvantage of the above-mentioned registered patent No. 920672 is that the durability improvement process by water retention agent and surface strengthening agent treatment and the coloring process by pigment treatment are performed separately and cumbersomely, and the organic combination of these two processes is carried out in order to achieve a synergistic effect. It is carried out directly on site, so in order to ensure reliability, it must be carried out very carefully when working on site

[0008] In particular, the above-mentioned registered patent No. 920672 does not disclose the most important components and contents of the coloring composition.
