The invention provides a coloring agent for the concrete ground and a preparation method of the coloring agent, and relates to a coloring agent and a preparation method thereof. The coloring agent for the concrete ground comprises raw materials as follows: primary-color pigments, a silane coupling agent, an antioxidant, polyvinyl alcohol, a polyacrylic acid emulsion, n-butyl alcohol, organic small molecular alcohol and 100 nm sericite powder. The preparation method comprises steps as follows: step one, sericite is dispersed in water and ground with a wet mixing method until the grain size of sericite is smaller than 200 nm, and the sericite is filtered and dried; step two, polyvinyl alcohol, the polyacrylic acid emulsion, n-butyl alcohol and organic small molecular alcohol are added and dispersed for 30-40 min, the primary-color pigments, the silane coupling agent and the antioxidant are sequentially added, and the mixture is subjected to ultrasonic dispersion to be uniform and is left to stand to obtain the coloring agent for the concrete ground. The product has the advantages of high penetration performance, extremely low surface strength, excellent wearing resistance, high tinting strength, uniform color distribution, stable hue and pure tone, and is safe, environment-friendly, non-toxic, odorless and free of acid and alkali corrosion; the coloring efficiency is high; the construction technology is simple, and the construction is fast, safe and controllable.
