Environmental-friendly dust suppressant and preparation method thereof

Abstract

The invention relates to an environmental-friendly dust suppressant and a preparation method thereof, which are characterized in that the environmental-friendly dust suppressant comprises the following components in percentage by mass: 0.10 to 3.50 percent of polyvinyl alcohol, 0.05 to 1.50 percent of urea, 0.10 to 1.50 percent of propanetriol, 0.10 to 1.50 percent of glycol, 0.05 to 1.00 percentof surfactant and 91 to 96 percent of water. The environmental-friendly dust suppressant is prepared in the following steps that: preparation of solution A; preparation of solution B; the prepared A and B solution is mixed and stirred uniformly to obtain dust suppressant stock solution; and when in use, the stock solution is directly diluted by water by ration on demand. The invention is characterized by no toxin, no pollution, no corrosion, scientific and reasonable formula, simple preparation process, low cost, safety, environmental protection and energy saving, can form a continuous hard shell with a certain strength on a surface after being sprayed on the surface of material, and the dispersed material is sealed below the hard shell so as to have a dust-proof function and bring wide economic and social benefits.

Description

technical field

[0001] The invention belongs to the technical field of environmental pollution control, and relates to a dust suppressant, in particular to an environment-friendly dust suppressant and a preparation method thereof. Background technique

[0002] In iron and steel enterprises and coal plant power generation enterprises, a large amount of raw materials such as coal and mineral bulk materials and wastes such as fly ash and tailing ash are often stored or transported. Surface solidification dust suppression is an effective method for solid dust control, which can prevent bulk materials from being blown up by the wind and reduce losses during bulk material transportation and stacking. The method utilizes the bonding and film-forming properties of the solidified dust suppressant to form an effective protective layer after spraying on the surface of the granular bulk material to achieve the purpose of dust suppression. This method is also applied to aspects such as ...
