Abstract

The invention discloses a road dust suppressant, and preparation and construction methods thereof, and belongs to the field of environmental protection and dust suppression. The road dust suppressant consists of the following components in percentage by weight: 0.1-2 percent of dispersible emulsion powder, 0.1-10 percent of an emulsion, 0.2-5 percent of a hygroscopic moisturizer, 0.01-0.5 percent of an absorbent, 2-10 percent of an anti-freezing agent, 0.1-0.2 percent of a wetting agent, 1-25 percent of filler and the balance of water. The road dust suppressant, and preparation and construction methods thereof disclosed by the invention have the benefits that inhalable particulate matters, nitric oxide, sulfide and other harmful matters on roads can be effectively reduced; the road dust suppressant has the characteristics that the environment is friendly, the hygroscopicity and the moisture retention are strong, the corrosion to vehicles and the roads is weak, and the road potential safety hazards cannot be caused.

Description

technical field [0001] The invention relates to the field of environmental protection and dust suppression, in particular to a road dust suppressant and its preparation and construction method. Background technique [0002] With the development of industry, air pollution has increasingly become an unavoidable and must-face environmental problem for the whole society. Among them, inhalable particulate matter is a serious pollutant that directly endangers people's health. The largest sources of inhalable particulate matter are coal combustion and automobile exhaust emissions. Among them, automobiles, as a common means of transportation, produce pollutants not only carbon oxides, nitrogen oxides, sulfur oxides, etc. from exhaust emissions, but also car driving. The dust brought in during the process and the carbon dust generated by the friction between the tire and the road surface. [0003] At present, in terms of road dust suppression, the main measure to reduce road dust a...
