Road dust inhibitor and preparation method thereof

Abstract

The invention discloses a road dust inhibitor and a preparation method thereof. The road dust inhibitor is characterized in that the raw materials of the road dust inhibitor comprises surface active agents, stabilizers, hydrophilic agents, thickeners, anti-freezing auxiliaries, antibacterial agents and water. The preparation method comprises, firstly, adding an appropriate amount of water into a reactor; secondly, adding the surface active agents and the stabilizers in; thirdly, after the surface active agents and the stabilizers are fully dissolved, slowly adding the hydrophilic agents and the thickeners in and stirring to achieve dissolution; fourthly, adding the anti-freezing auxiliaries and the antibacterial agents in; lastly, adding the residue water in until reaching a designated concentration. By means of the surface active agent, the road dust inhibitor can form a layer of isolating film on the contact surface between dust and air, and the isolating film has high water carry capacities and adhesive performance; by adding a small amount of salt, the road dust inhibitor obtain certain anti-freezing and antibacterial effects.

Description

technical field

[0001] The invention belongs to the field of environmental protection, and relates to a dust suppressant, in particular to a road dust suppressant and a preparation method thereof. Background technique

[0002] At present, my country's air quality is worrying, and smog and PM2.5 are hard to guard against, seriously affecting people's lives and health. Investigating its root cause, there are many sources of pollutants. The main air pollutants in most northern cities are inhalable particulate matter. Particulate pollutants mainly come from construction sites, garbage dumps and road dust. Most of the material accumulation on the construction site is in the open air. After being exposed to wind and sun, the surface of the material pile is refined, and it is easy to enter the atmosphere to form particulate pollutants. Therefore, piled materials such as construction sites and garbage piles are the main sources of urban dust. The dust particles enter the air, sl...

preparation example Construction

[0030] The preparation method of road dust inhibitor of the present invention, carries out as follows:

[0031] Add an appropriate amount of water to the reaction kettle, add 10%-15% of surfactant and 10%-15% of stabilizer, and slowly add 5%-10% of hydrophilic agent and stabilizer after the surfactant and stabilizer are fully dissolved. 5%-10% of the thickener is stirred and dissolved, and finally 5%-10% of the antifreeze additive and 5%-10% of the antibacterial agent are added, and finally water is added to the specified concentration to obtain the road dust inhibitor.

[0032] in:

[0033] The surfactant is selected from one or a mixture of APG, sodium alginate, phytosterol and tea saponin.

[0034] The stabilizer is selected from one or a mixture of polyethylene glycol and polyvinyl alcohol.

[0035] The hydrophilic agent is selected from one or a mixture of sucrose and water-soluble starch.

[0036] The thickener is selected from one or a mixture of sodium silicate, hyd...

Embodiment 1

[0041] Calculated by weight percentage, the total amount of each raw material is 100%; add an appropriate amount of water to the reaction kettle, add 15% tea saponin and 15% polyethylene glycol, and wait until the tea saponin and polyethylene glycol are fully dissolved Then slowly add 10% sucrose and 10% sodium silicate and stir to dissolve, finally add 5% sodium chloride and 5% sodium benzoate, and finally add the remaining water to make the product reach the specified concentration to obtain the road dust inhibitor.

[0042] When used on site, dilute the product with water at a ratio of 1:200, load it into a spray truck, and spray the road to prevent dust. The dust concentration in the air before spraying dust remover is 90mg.m 3 . After spraying the dust remover, the dust concentration in the air is 20.2mg.m 3 . The dust removal efficiency is 77.6%. The dust removal effect is obvious.

Embodiment 2

[0044] Calculated by weight percentage, the total amount of each raw material is 100%; add an appropriate amount of water to the reactor, add APG15% and polyethylene glycol 10%, and wait until sodium lauryl sulfate and polyethylene glycol are fully dissolved Then slowly add 5% water-soluble starch and 10% sodium silicate and stir to dissolve, then add 5% sodium chloride and 5% sodium benzoate, and finally add the remaining water to make the product reach the specified concentration to obtain the road dust inhibitor.

[0045] When used on site, dilute the product with water at a ratio of 1:100, put it into a spraying vehicle, and spray the road to prevent dust. The dust removal efficiency is high and the dust removal effect is obvious.
