Abstract
The present invention discloses a kind of dust suppressant of multi-environment depositing dust, including the following raw material ingredient and weight percent：Surfactant 10 40%, ethylene glycol 5 20%, glycerine 5 10%, thickener 1 5%, fungicide 0.2 1%, deionized water 40 70%.The dust suppressant reduces the surface tension of water, is sprayed in air in a manner of wet operation, and water mist is combined with the dust particles in air, forms the aggregate of dust and water mist, is then reached dust suppression purpose by gravitational settling.
Description
Technical field
The present invention relates to environmental technology fields, and in particular to a kind of dust suppressant and preparation method thereof of multi-environment depositing dust.
Background technology
It is well known that construction site, urban pavement, open coal mine, more dust workshop all in dust atmosphere pollute, especially
It is 10 microns of dust below of diameter, it is difficult to natural subsidence, seriously affects the health of the mankind, up to the present, tradition
Dust-proof use wet operation (i.e. watering or atomized water spray) it is limited for fine particles inhibiting effect, dust-laying effect is bad, and
Water consumption is big.
Invention content
The present invention in view of the shortcomings of the prior art, provide a kind of dust suppressant and preparation method thereof of novel multi-environment depositing dust,
This dust suppressant is diluted in 1: 500~1: 1000 ratio with tap water, the surface tension of water is reduced, with wet operation side
Formula is sprayed in air, and water mist is combined with the dust particles in air, forms the aggregate of dust and water mist, then heavy by gravity
Drop reaches dust suppression purpose.
A kind of dust suppressant of multi-environment depositing dust, including the following raw material ingredient and weight percent：
A kind of dust suppressant of multi-environment depositing dust, the surfactant is neopelex, alkyl phenol is poly-
Ethylene oxide ether, fatty alcohol polyoxyethylene ether, polyoxyethylene carboxylate, sorbitan ester, alkylolamides polyoxyethylene ether
One or more of mixing.
A kind of dust suppressant of multi-environment depositing dust, the thickener are polyvinyl alcohol and/or xanthans.
A kind of dust suppressant of multi-environment depositing dust, the fungicide are dodecyl benzyl dimethyl ammonium chloride, 12
One or more of Alkyl dimethyl benzyl ammonium bromide, myristyl benzyl dimethyl ammonium chloride mix.
A kind of preparation method of the dust suppressant of the multi-environment depositing dust, includes the following steps：
(1) 10-40% surfactants, 1-5% thickeners and 40-70% deionized waters are added in reactor, constant temperature
Heating stirring is to being completely dissolved；
(2) ethylene glycol 5-20%, glycerine 5-10%, fungicide 0.2-1% are slowly added to and are stirred evenly, clarified
Transparent solution, i.e. dust suppressant stoste.
The preparation method, the whipping temp in step (1) are 40-50 DEG C, and mixing time is 30~40min.
The preparation method, the whipping temp in step (2) are 30-40 DEG C, and mixing time is 10~20min.
The preparation method, the dust suppressant stoste that step (2) obtains, when in use as needed according to 1: 500~1:
1000 ratio is diluted use with tap water.
The invention has the advantages that：
The present invention uses the surfactant of biradical end (hydrophobic group, hydrophilic group), by shape between hydrone and dust particles
At bridge, to which dust particles are wrapped up by hydrone.It is captured again by moisture attached bag by the thickener of macromolecular network structure
The dust wrapped up in, forms the aggregate of dust and water mist, and this dust-suppression method can adequately capture 10 microns of micronic dusts below of diameter
Then suspended particulate is reached dust suppression purpose by gravitational settling.It can be used for construction site, urban pavement, open coal mine, more dust
The dust suppression of a variety of adverse circumstances such as workshop uses.
