Embodiment 1

[0035] A kind of preparation of cleaning soil-fixing and dust-suppressing agent, described dust-suppressing agent is calculated by 100 parts by weight, and its raw material composition is:

[0036]

[0037]

[0038] The balance is water.

[0039] Specific steps: Dissolve corresponding proportions of sodium silicate and sodium carboxymethylcellulose in water and corresponding proportions of glycerol in a three-necked flask at a reaction temperature of 45° C. and fully mix and react for 15 minutes. Then add pure acrylic emulsion to the mixed solution prepared by the reaction, fully react and mix for 30 minutes at 30°C, and finally add sodium dodecylbenzenesulfonate solution and continue to fully react and mix for 15 minutes at 30°C to obtain the clean soil-fixing pH Dust final product. The dust suppression efficiency of the dust suppressant is as high as 98.6%, and the dust suppression period is as long as 30 days.

Embodiment 2

[0041] A kind of preparation of cleaning soil-fixing and dust-suppressing agent, described dust-suppressing agent is calculated by 100 parts by weight, and its raw material composition is:

[0042]

[0043] The balance is water.

[0044] Specific steps: Dissolve corresponding proportions of sodium silicate and sodium carboxymethylcellulose in water and corresponding proportions of glycerol in a three-necked flask at a reaction temperature of 45° C. and fully mix and react for 15 minutes. Then add pure acrylic emulsion to the mixed solution prepared by the reaction, fully react and mix for 30 minutes at 30°C, and finally add sodium dodecylbenzenesulfonate solution and continue to fully react and mix for 15 minutes at 30°C to obtain the clean soil-fixing pH Dust final product. The dust suppression efficiency of the dust suppressant is as high as 95.3%, and the dust suppression period is as long as 27 days.

Embodiment 3

[0046] A kind of preparation of cleaning soil-fixing and dust-suppressing agent, described dust-suppressing agent is calculated by 100 parts by weight, and its raw material composition is:

[0047]

[0048] The balance is water.

[0049] Specific steps: Dissolve corresponding proportions of sodium silicate and sodium carboxymethylcellulose in water and corresponding proportions of glycerol in a three-necked flask at a reaction temperature of 45° C. and fully mix and react for 15 minutes. Then add pure acrylic emulsion to the mixed solution prepared by the reaction, fully react and mix for 30 minutes at 30°C, and finally add sodium dodecylbenzenesulfonate solution and continue to fully react and mix for 15 minutes at 30°C to obtain the clean soil-fixing pH Dust final product. The dust suppression efficiency of the dust suppressant is as high as 96.1%, and the dust suppression period is up to 25 days.

Abstract

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.

Description

technical field [0001] The invention belongs to the field of chemical industry, and relates to a method for preventing and controlling environmental pollution, in particular to a cleaning, soil-fixing and dust-suppressing agent and a preparation method thereof. Background technique [0002] In today's rapid economic development, poor air quality has always been a serious problem facing our country. In recent years, the problem of smog has been heard more and more. In the northern cities of our country, the environmental protection department is struggling with air quality due to the characteristics of the climate. Among them, fugitive dust accounts for a considerable proportion of the total suspended particulate matter in urban air, but we lack systematic research on dust pollution, which makes the contribution of fugitive dust to atmospheric particulate matter more and more important. With the advancement of my country's urban integration, there will inevitably be more pro...
