Problems solved by technology

However, this method needs to prepare sodium carboxymethylcellulose grafted acrylamide polymer, and its cost is too high to be used in large quantities.
[0006] Although the above-mentioned dust suppressants can settle the dust to a certain extent, they generally have disadvantages such as poor degradability and great environmental pollution, and are expensive to use, so they cannot comprehensively realize economic and environmental benefits.

Abstract

The invention provides an environment-friendly wetting type dust suppressant, a preparation method, a use method and application thereof. The environment-friendly wetting type dust suppressant is prepared from the following components in percentage by mass: 2-10% of a non-ionic surfactant, 2-5% of a zwitterionic surfactant, 0.01-1% of an inorganic salt additive, 0.2-1.5% of a moisture absorbent and the balance of water, wherein the non-ionic surfactant comprises alkyl glycoside and fatty alcohol-polyoxyethylene ether, and the zwitterionic surfactant is prepared from lecithin. According to theenvironment-friendly wetting type dust suppressant provided by the invention, the surface tension of water is reduced by adding the wetting agent, so that dust particles, especially hydrophobic dust particles, can be wetted more easily, the dust starting wind speed is increased, and dust raising is relatively not likely to happen; and the environment-friendly wetting type dust suppressant can be used in places such as storage yards, roads, belt transportation and the like, and achieves the purpose of effectively treating dust pollution in open environments.

Description

technical field [0001] The invention belongs to the technical field of environmental pollution control, and relates to a dust suppressant and a preparation method thereof, in particular to an environment-friendly wetting dust suppressant, a preparation method, a use method and an application thereof. Background technique [0002] The hazards of dust to humans and the environment are well known. If humans inhale high-concentration dust for a long time, the incidence of lung disease will increase. Strong dust particle stimulation can cause respiratory inflammation such as bronchitis, rhinitis, and pharyngitis; Corrosion, the impact on environmental sanitation is also very prominent. Therefore, the research and development of dust control technology has been highly valued, and its development level is also constantly improving. [0003] At present, dust suppression methods mainly include sprinkling dust suppression, wind-shielding dust suppression net dust suppression, coveri...
