Road dust suppressant and preparation method thereof

Abstract

The invention discloses a road dust suppressant. The road dust suppressant is prepared from, by weight, 5-10% of sodium diethylhexyl sulfosuccinate, 88-93% of glycerol, 0.5-2% of carboxymethylcellulose, 0.1-0.3% of polyacrylamide, and the balance of water for preparation. The road dust suppressant has the advantages of easily obtained components, easiness in preparation, substantial flying dust adsorption effect, and good penetration and moisture retention effects, and the highly-viscose carboxymethylcellulose and polyacrylamide also have an incrustation and dust proofing effects on road surfaces; the road dust suppressant is nontoxic and has no irritation to skins, so the dust suppressant has no threat to the body health of dust suppressant sprinkling workers and passerby; and the dust suppressant has low cost, is suitable for being used in long-distance railway coal transport, road transport, and especially the non-pavement road transport process, and has a substantially better dust suppressing effect than traditional water sprinkling dust suppression and common road dust suppressants.

Description

technical field [0001] The invention relates to the technical field of environmental protection, in particular to a road dust suppressant and a configuration method thereof. Background technique [0002] Dust pollution is one of the main factors leading to environmental pollution. During the transportation of railways, highways and non-paved roads, a large amount of dust is often generated, which not only directly threatens the safety of production and transportation, but also causes great pollution to the surrounding environment. The most commonly used method to suppress road dust is artificial or machine sprinkling. The main function of sprinkling is to moisten the fine dry dust, increase its relative density, and bond into larger particles, which fall on the ground, but the effect is limited and It has caused a great waste of water resources. In today's increasingly scarce water resources, sprinkling water to suppress dust is no longer a long-term practice. There are man...

The most commonly used method to suppress road dust is artificial or machine sprinkling. The main function of sprinkling is to moisten the fine dry dust, increase its relative density, and bond into larger particles, which fall on the ground, but the effect is limited and It has caused a great waste of water resources. In today's increasingly scarce water resources, sprinkling water to suppress dust is no longer a long-term practice. There are many types of dust suppressants on the market, and the components are also different. Various deficiencies, such as weak adsorption and binding force between dust suppressant molecules and coal dust, too fast evaporation of water, poor dust sealing, etc.
