Flying dust inhibitor for environmental protection and preparation method thereof

Abstract

The invention discloses a flying dust inhibitor for environmental protection. The flying dust inhibitor comprises the following components (in percentage by mass): 55-60 percent of water; 18-23 percent of a reinforcing agent; 5-10 percent of a coagulant; 7-12 percent of a surfactant; 2-5 percent of a bacteriostatic agent; silicic acid gel is alternately generated through a sodium silicate solutionand a calcium chloride solution; a layer of silicic acid gel film is formed on the surface of the dust in a wet environment to reinforce dust and avoid dust raising phenomenon; bentonite is added into the flying dust inhibitor, the moisture loss of dust can be reduced, moisture is locked in molecules for a long time and the surface of the dust is kept moist so as to achieve the flying dust inhibition function, improve the moisture retention and the adhesion of the flying dust inhibitor, ensure the humidity of the silicic acid gel layer formed on the surface of the dust, improve the adhesion strength of the silicic acid gel layer formed on the surface of the dust, effectively inhibit the flying dust flying, and provide the long-term flying dust flying.

Description

technical field [0001] The invention relates to the technical field of dust suppressants, in particular to a dust suppressant for environmental protection and a preparation method thereof. Background technique [0002] Flying dust is an open pollution source that enters the atmosphere due to the dust on the ground being driven by wind, man-made or other drives, and is an important part of the total suspended particulate matter in the ambient air. [0003] The dust suppressant is composed of new multifunctional polymers; the degree of cross-linking between polymer molecules will form a network structure, and there are various ionic groups between the molecules, which can generate strong affinity with ions. Heli; its mechanism of action is to capture, absorb, and agglomerate dust particles, and lock them tightly in the network structure, so as to play the role of wetting, bonding, condensation, moisture absorption, dustproof, anti-corrosion and anti-scouring; Dust suppressant...

Problems solved by technology

[0006] The treatment effect of the existing dust suppressant cannot last for a long time; the dust suppressant lacks a strong binder to tightly bond the particles in the fly ash, the particles are small, and the water retention is poor. blow up
