Clean soil-stabilizing and dust-suppression agent and preparation method thereof

The invention provides a clean soil-stabilizing and dust-suppression agent which is composed of, by weight, 2-5 parts of sodium silicate, 0.3-0.6 part of sodium carboxymethylcellulose, 1.5-2 parts of glycerol, 5-10 parts of pure acrylic emulsion, 0.25-1 part of sodium dodecyl benzene sulfonate and the rest of water. The invention also provides a preparation method of the above clean soil-stabilizing and dust-suppression agent. The preparation method comprises the following steps: firstly dissolving sodium silicate and sodium carboxymethylcellulose in water, adding the solution and glycerol into a reaction vessel, fully mixing at the temperature of 40-50 DEG C, adding pure acrylic emulsion, fully reacting and mixing at 25-35 DEG C, adding a sodium dodecyl benzene sulfonate solution, and continuously fully reacting and mixing so as to obtain a clean soil-stabilizing and dust-suppression agent. The dust-suppression agent of the invention has bonding and moisture-absorption effects, and has strong anti-evaporation property and good permeability. Effective dust suppression time is as long as 30 d, and dust suppression efficiency is maintained to be 95% and above.
