Problems solved by technology

However, the effective dust suppression time of the dust suppressant is short, only 5 days, and the ability to resist the crushing of heavy trucks is poor, so it is not suitable for use on roads transported by a large number of heavy trucks
[0008] Therefore, there are few existing dust suppressants that can be truly applied to effectively suppress dust when a large number of trucks are transported on the open road, and there are common problems such as not being resistant to rolling, short dust suppression time, and corrosion of vehicles. Development of new low-cost, high-quality Long-lasting dust suppressant is very necessary

Abstract

The invention discloses a road dust suppressant, which is prepared by mixing and blending 0.1-2.0% of water-soluble high molecular polymer, 20-50% of moisture absorption humectant, 1.0-5.0% of preservative, 0.5-5.0% of penetrating agent and the balance water. The road dust suppressant is a dynamic dust-proof and dust-suppressing liquid product which combines functions of wetting, bonding, permeating, adsorbing moisture and the like into a whole and has extremely strong pressurization-resistant function. The road dust suppressant has the advantages of obvious anti-evaporation performance and good water retention hygroscopicity, and dust on the road surface can be coagulated and is unlikely to fly. The road dust suppressant disclosed by the invention not only can be applied to road dust suppressing but also can be simultaneously used for the aspects, such as the mine exploration and transportation environment, storage yards of coal ash, coal and other ores, and the treatments of municipal construction earthwork dust raise.

Description

technical field [0001] The invention relates to the technical field of environmental pollution control, in particular to a dust suppressant for suppressing road dust. The road dust suppressant of the invention is especially suitable for controlling dust during the operation of heavy trucks. Background technique [0002] Dust pollution is one of the main factors leading to environmental pollution. In production and storage sites such as ports, power plants, cement plants, and coal storage yards, as well as during railway and road transportation, a large amount of dust is often generated, which not only directly threatens the safety of production, but also causes great pollution to the surrounding environment. [0003] Dust pollution is particularly serious in surface mining. With the continuous increase of open-pit mining in my country, the production intensity continues to increase, the level of mechanization continues to improve, and the dust pollution in production operat...
