| description | The invention provides a dust suppressant as well as a preparation method and application thereof. The dust suppressant is prepared from the following components in percentage by mass: 0.018 to 1.32 percent of hydrotalcite, 1.30 to 12.5 percent of polyvinyl alcohol, 0.99 to 5.13 percent of soluble starch, 1.73 to 9.38 percent of macromolecular binder, 0.027 to 1.32 percent of anionic surfactant and the balance of water. Hydroxyl groups of polyvinyl alcohol and the strong permeability of the anionic surfactant can modify hydrotalcite, so that the wettability of the dust suppressant on solid waste residues is effectively improved, the dust suppressant has a good water retention effect, the effective dust suppression time of the dust suppressant can be prolonged, and the service life of the dust suppressant is prolonged. The organic binder and the soluble starch can increase the binding adsorption capacity of the dust suppressant to a dust sample; after the dust suppressant with the specific composition is used |
