Abstract
The invention discloses a method for preparing a double-component fine dust agglutinant and belongs to the field of agglutinants. Acrylamide and sodium hydroxide are dissolved in water and then undergo a reaction with acrylic acid and then undergo coupling with nano-silica to obtain a component A, ethylene glycol, glycerol and water are mixed to obtain a component B, and in use, the fine dust agglutinant which is low in cost and convenient to store and can effectively agglutinate fine dust in air is prepared in a mode of mixing the component A and the component B.
Description
Technical field
The present invention relates to agglutinant, particularly the technical field of the agglutinant of tiny dust in gas.
Background technology
The diameter be present in air is that the quality of solid particulate on air of 0.1 ~ 5 μm has significant impact, particularly diameter to be the particulate matter of about 2.5 μm, i.e. PM2.5 is very serious to the infringement of air, very harmful to human body.These fine dusts are difficult to because volume is little, specific surface area defines metastable aerosol greatly, in atmosphere remove, and some the general physical filtering methods for the larger particle of particle diameter can not play similar effect in the removal of fine dust.
For this problem, at present the higher certain methods of efficiency is eliminated to fine dust and all have employed the thinking first for fine dust aggegation removed again.
Summary of the invention
The object of the present invention is to provide a kind of can effectively aerial fine dust be carried out aggegation, easy to use, be easy to the preparation method of agglutinant that preserves.
Technical scheme of the present invention is as follows:
A preparation method for pair component fine dust agglutinant, described agglutinant comprises A, B two components, and wherein the preparation of component A comprises the following steps:
1) acrylamide, sodium hydroxide is soluble in water, obtain the first solution after stirring, by this solution warms to 80 ~ 90 DEG C, keep backflow under nitrogen atmosphere;
2) in the first solution, add vinylformic acid, be uniformly mixed, constant temperature backflow obtained the second solution after 4 ~ 6 hours;
3) the second solution is cooled to 60 ~ 70 DEG C, adds silane coupling agent wherein, add nano silicon after stirring, constant temperature obtains the 3rd solution after stirring 10 ~ 20min;
4) the 3rd solution heating evaporation is overflowed completely to moisture, namely obtain described component A;
The mixture of the ethylene glycol of described B component to be mass ratio be 1:1:10 ~ 15, glycerol and water;
In use, component A is mixed with B component.
Its preferred embodiment for: described in described first solution, the mass ratio of acrylamide, sodium hydroxide, water is 20 ~ 30:4 ~ 6:100.
Its another preferred embodiment is: described acrylamide and described acrylic acid mass ratio are 1.5 ~ 2:1.
Its another preferred embodiment is: the mass ratio of described acrylamide and described nano silicon is 20 ~ 30:5 ~ 7.
Its another preferred embodiment is: the mass ratio of described acrylamide and described ethylene glycol is 20 ~ 30:8 ~ 10.
Its another preferred embodiment is: the quality of described silane coupling agent is 1% ~ 1.5% of described nano silicon quality.
When reality uses, A, B component mixing can directly be sprayed after shaking up in the air containing more fine dust, after spraying, fine dust can drop because being aggregated into larger agglomerate, also can assist further and use general filter plant to carry out dust-filtering.
Process of the present invention is simple, and cost is lower, and aerial fine dust effectively can be carried out aggegation by products therefrom, is convenient to the removal of fine dust, and product of the present invention is easy to preserve simultaneously, easy to use.
