The invention relates to a dust suppressant and a preparation method thereof. The dust suppressant comprises the following raw materials in parts by weight: 0.05-0.15 part of polyanionic cellulose, 0.01-0.09 part of Triton X-100, 0.03-0.07 part of a functional additive and 100 parts of water. The dust suppressant has the advantages that olyanionic cellulose and Triton X-100 are utilized in a matched manner, so that an excellent coagulation and dust suppression effect is generated on raised dust within a short time, and the dust suppressant is suitable for dust suppression for dynamic coal flow; meanwhile, the raised dust is coagulated to form large particles through penetration and wetting, so that rapid falling is realized for dust suppression; compared with the conventional dust suppressant, the dust suppressant provided by the invention eliminates the dust suppression method that a solidified layer is formed on the surface of coal flow through crusting, so that the impact of the dust suppressant on coal loading, unloading, transferring, and conveying on a belt is avoided; besides, the dust suppressant further has the advantages of being easy to degrade, environmentally friendly, pollution-free, and low in cost.
