Wetting type composite road surface dust suppressant and use method thereof

Abstract

The invention provides a wetting type composite road surface dust suppressant. The wetting type composite road surface dust suppressant consists of a moisture absorbent, a humectant, a thickening agent and a surfactant. The moisture absorbent is selected from lithium bromide, lithium chloride or fructose, the humectant is selected from PCA-Na, trimethylglycine or polyethylene glycol, the thickening agent is selected from sodium carboxymethyl cellulose, amine oxide, water glass or polyacrylamide, and the surfactant is selected from sodium dodecyl benzene sulfonate, sodium dodecyl sulfate or sodium succinate. The wetting type composite road surface dust suppressant has the advantages of no toxicity, no side effect, low price, excellent performance, long effective action time, no environmental pollution, easily available raw materials and convenience in use.

Description

[Technical field] [0001] The present invention belongs to the field of environmental protection. More specifically, the present invention relates to a wet type composite pavement dust collecting agent, and also relates to the use of the wet-type composite pavement dust collecting agent. 【Background technique】 [0002] With the development of social economy, the acceleration of industrialization and urbanization process, environmental pollution problems are increasing. The dust pollution problem is a worldwide problem, and the harm to humans is also more serious. No tissue dust emissions as one of the main sources of air pollution, causing serious harm to people's living environment and personal health, has become the focus of governance in recent years. The urban hardening road dust is the main source of urban secondary dust. At present, people have made a large number of research work in inhibiting dust pollution, such as CN 102660226 A discloses a polymer polymer dust collectin...

AI Technical Summary

Problems solved by technology

However, there are still some technical problems in these dust suppressants, for example, some dust suppressants have poor bonding and adsorption effects, short lasting moisturizing effect, some hygroscopic salts are corrosive, and the cost of dust suppression is high

[0003] In addition, at present, water spraying method is mainly used at home and abroad to suppress dust on the road surface. Sprinkling water is simple and convenient, but the evaporation speed is fast and the action time is short, which cannot meet the long-term and effective dust suppression requirements for roads with large dust thickness.
