[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.
