Efficient dust suppressant for preventing and treating building dust pollution and preparation method of efficient dust suppressant

The invention provides an efficient dust suppressant for preventing and treating building dust pollution and a preparation method of the efficient dust suppressant, and relates to the technical field of preparation of dust suppressants. The efficient dust suppressant is prepared from the following raw materials in percentage by weight: 0.5 to 1.0 percent of polyacrylamide, 0.15 to 0.30 percent of pectin, 0.15 to 0.30 percent of sodium lignin sulfonate, 0.05 to 0.15 percent of an initiator, 0.05 to 0.10 percent of a cross-linking agent, 0.25 to 2.50 percent of a water-retaining agent, 0.125 to 1.125 percent of a surfactant and the balance of water. The efficient dust suppressant is wide in raw material source, simple in preparation condition, higher in viscosity and wettability compared with water, high in water retention capacity, capable of effectively improving the solidification strength of dust and good in dust falling effect. 本发明提供了一种防治建筑粉尘污染的高效抑尘剂及其制备方法，涉及抑尘剂的制备技术领域。本发明高效抑尘剂按重量份数配比的原料是0.5%~1.0%聚丙烯酰胺、0.1
