Embodiment 1

[0028] Add 0.8g of polyanionic cellulose and 0.4g of hydroxypropyl methylcellulose into 85g of water, and stir evenly to obtain a matrix solution; dissolve 0.2g of calcium chloride and 0.25g of potassium carbonate in 12.59g of water, and add the calcium chloride solution to Stir the matrix solution evenly, then add the potassium carbonate solution into the matrix solution and stir evenly; continue to stir for 3 hours, during which time add 0.05g xylitol, 0.01g fatty acid sulfoalkyl ester, and 0.7g urea in turn to obtain an environmentally friendly construction site dust suppressant finished product.

Embodiment 2

[0030] Add 1.6g of sodium carboxymethylcellulose and 0.3g of hydroxypropylmethylcellulose into 80g of water, and stir evenly to obtain a matrix solution; dissolve 1.2g of sodium silicate and 0.89g of oxalic acid in 15.11g of water, and dissolve the sodium silicate solution Add the matrix solution and stir evenly, then add oxalic acid into the matrix solution and stir evenly; continue stirring for 4 hours, during which time add 0.4g glycerol, 0.3g sodium dodecylbenzenesulfonate, and 0.2g urea in sequence to obtain an environmentally friendly construction site Finished dust suppressant.

Embodiment 3

[0032] Add 2.5g of hydroxyethylcellulose and 0.05g of hydroxypropylmethylcellulose into 80g of water, and stir evenly to obtain a matrix solution; dissolve 0.31g of calcium nitrate and 0.2g of sodium carbonate in 14.04g of water, and add the calcium nitrate solution to the matrix Stir the solution evenly, then add sodium carbonate to the matrix solution and stir evenly; continue to stir for 5 hours, during which time, add 0.9g propylene glycol, 1g succinate sulfonate, and 1g urea in sequence to obtain the finished environmental-friendly dust suppressant for construction sites.

Abstract

The invention discloses environment-friendly construction site dust suppressant and a preparing method thereof. The dust suppressant comprises, by weight, 0.8% to 2.5% of water-soluble macromolecule polymer matrix, 0.05% to 1.5% of macromolecule polymer builder, 0.2% to 2% of A particle precursor, 0.2% to 1% of B particle precursor, 0.05% to 1.5% of cross-linking agent, 0.01% to 1% of surface active agent and 0. 01 % to 1% of mobility modifier. Raw materials of the dust suppressant are industrial grade drugs and industrial water, and the dust suppressant can be produced under normal pressure and temperature and have no pungent odor and is low in cost. The purpose of the environment-friendly construction site dust suppressant is to govern swirling dust caused by open-air source on the construction site, and the dust suppressant is used in material piles and road surfaces, can form a layer of a solidification shell and have the advantages of being small in solidification shell crack, long in duration and environmentally friendly. The dust suppressant is beneficial to the physical and psychological health of constructors, reduces the waste of raw materials, maintains good environment around a construction unit and can produce great economic benefits and social benefits.

Description

technical field [0001] The invention belongs to the technical field of environmental protection, and in particular relates to an environment-friendly construction site dust suppressant and a preparation method thereof. Background technique [0002] The rapid development of the national economy has led to the vigorous rise of municipal construction, followed by a large number of dust generated by construction sites during the construction process, but it has a very bad impact on the surrounding environment. Statistics show that construction site dust accounts for more than 20% of the city's total dust, and the PM10 produced is about 10% of the entire city. Therefore, strict control of dust pollution on construction sites is one of the important means to improve the air environment. [0003] At present, the prevention and control measures for open dust sources mainly include sprinkling water to suppress dust, covering dust with thatch, setting up windshield walls to suppress ...
