Dustfall agent cardinal principle is to be soaked, adhered to dust using dustfall agent, is increased weight after making dust moisture absorption, to settle.For
When Dust Capacity is up to every square metre of 80g or more, existing 1.5-2 times of dustfall agent increment amount could be purified air quality to Dust Capacity
Lower than 10g/m3, will cause dust in this way and glued compared with the mixture of dustfall agent, there is obvious viscous sense to people's sense organ, still can
It influences people to be open to traffic and walk on urban road, and higher cost.
Summary of the invention
In view of the deficiencies of the prior art, the present invention intends to provide a kind of dustfall agent containing sodium alginate,
It has preferable dust-laying effect for high-content, excess soot region.
To achieve the goals above, the invention provides the following technical scheme:
A kind of dustfall agent containing sodium alginate, including the solidifying flocculating composition of figuration auxiliary material, rush, inorganic salts and water；It is described
Promoting solidifying flocculating composition includes sodium alginate, ammonium polyacrylate, citric acid and cellulose suspension；The sodium alginate accounts for depositing dust
The 0.5-10% of agent total weight, the sodium alginate molecular weight are greater than or equal to 10000000D；The cellulose suspension accounts for drop
The 0.1-1.0% of dust agent total weight.
In the present invention, further, the sodium alginate accounts for the 2-6% of dustfall agent total weight, with the cellulose
Suspension quality ratio is 10-20:1.
In the present invention, further, the preparation method of the cellulose suspension: powdered cellulose is crushed, mistake
100-200 mesh disperses to form wadding according to volume ratio with acrylamide or its copolymer and/or sodium acrylate copolymer for 1:10
Shape liquid.
In the present invention, further, the polyvalent mineral salt is calcium chloride or calcium chloride and ferric sulfate, aluminum sulfate, chlorine
Change one or two kinds of combination of the above in aluminium.
In the present invention, further, the figuration auxiliary material accounts for the 2.0-5.0% of dustfall agent total weight；The figuration is auxiliary
Material includes component A and component B, and the two weight ratio is 3:1-2；The component A is selected from Arabic gum, tragacanth, locust bean gum, Huang
The one or two kinds of and above mixture in virgin rubber, guar gum.
In the present invention, further, the component B is selected from modified starch, gelatinized starch or both mixture.
In the present invention, further, the dustfall agent further includes disintegrative system, and the disintegrative system includes at least one
The composition of the disintegrating agent of cellulose and its derivates, water-soluble polyacid and weak base.
In the present invention, further, the disintegrating agent is selected from methylcellulose, carboxymethyl cellulose, carboxyethyl methylphosphinate
The one or two kinds of and above mixture in cellulose, carboxylic propyl methocel, it is described water solubility polyacid be selected from malonic acid,
Adipic acid or both mixture, the weak base are sodium bicarbonates.
In the present invention, further, content of the disintegration in water system in the dustfall agent is less than or equal to
30%.
A kind of preparation method of the dustfall agent containing sodium alginate, preparation method includes the following steps:
(1) sodium alginate, ammonium polyacrylate, citric acid are sequentially placed into blender, it is outstanding that cellulose is added while stirring
Supernatant liquid is sufficiently stirred and thick liquid nano is made to get the solidifying flocculating composition of the rush；
(2) figuration auxiliary material is soluble in water, it is uniformly mixed to form mixed liquor；Machine salt is soluble in water, is stirred
Even formation saturated solution, it is spare；
(3) thick liquid nano that step (1) obtains is promoted solidifying flocculating composition to be slowly added in remaining water, stirring to mixing
Uniformly, static 5-12h sequentially adds the mixed liquor and remaining ingredient of step (2) preparation after its completely defoaming, is uniformly mixed
