Abstract

The invention discloses a fluorosilicone resin waterproof colorant and a preparation method thereof, and belongs to the technical field of colorant. The colorant is a semitransparent colored agent andis used for making up for chromatic aberration existing on the surface of a cement base; the colorant comprises the following components by the weight percentage: 10%-50% of an organosilicon emulsion; 1%-10% of a small-molecular permeable material; 1%-10% of a fluororesin emulsion or fluorocarbon modified acrylic emulsion; 5%-40% of an opaque spherical polymer emulsion; 0.1%-1.3% of a catalyst; 2%-10% of a photocatalytic material powder or suspended photocatalyst; 1.2%-2.5% of a defoamer; and the balance water. The problems that a product in the prior art is unable to solidify at room temperature, poor in hardness and wear resistance of a coating layer and unable to decompose pigments and specific binders are solved; the colorant makes visual compensation for the color difference existingon the surface of the cement base so as to achieve color uniformity.

Description

technical field [0001] The invention relates to a color pulling agent and a preparation method thereof, in particular to a fluorosilicone resin waterproof color pulling agent and a preparation method thereof, belonging to the technical field of color pulling agents. Background technique [0002] The color of GRC decorative concrete slabs is mainly formed by mixing white cement or ordinary cement with various color pastes or toners. At the same time, specific texture, color and texture are formed on the GRC surface through other processes, so that the assembly of each GRC slab Finally, the value of expressive art is achieved. GRC decorative concrete is an extremely complex mixed product. There are many reasons that cause the color of each piece of GRC to be slightly different. After being installed on the exterior wall of the building, the color difference will eventually be formed. A piece of GRC may already have color difference problems when it is demoulded, such as the di...
