Description
Technical field
The present invention relates to a kind of highway coal transportation dust-depressors and preparation method thereof, belong to dust suppressant technical field.
Background technique
Fugitive dust is the decentralized system using gas as decentralized medium, solid-state fine particle for dispersed phase in highway Coal Transport.
Its fugitive dust factor is mainly: 1, dust is dry, oxidizable, make surface particles become smaller to be formed it is powdered.2, extraneous to stop without radix saposhnikoviae
Device is affected by the wind.
Common dust is mainly collectively formed by organic fillers such as coal miberal powder particle, dust particles.In Automobile Transportation mistake
In journey gravity, wind-force drive under bleed around to form dust pollution around.
Thus be directed to above situation, to catch dust suppression fine particle be outside air humidity, flash, stream amount, drop etc. because
The key of element variation and floating, with the large area of present high-tech means manufacture fine particle, deep degree connection mechanism, to have
Firmly the solidifying it of effect is integrated, and is made it not recede from, except material heap structure organization, can both be prevented and reduce coal
Transport fugitive dust.
Dust suppression spray water first is that increasing the water content of coal, the especially water content of skin granulate preferably reaches water content
6%-8%, to increase the weight of particle；Second is that changing dirt source surface particle diameter distribution, the distribution of mainly micro- wholegrain, by ability of swimming mist
Micro- wholegrain is captured or agglomeration, dust moisture absorption will lead to cohesion, influences the degree of scatter of particle.
Absorption water in dust is coated on dust particles surface in the form of moisture film, actually its group being dust particles
At part.Moisture film is coated on the surface of dust colloid with great suction, and this power maximum can reach 10000 atmospheric pressure
(142000osi).But since ambient humidity is changed the content of this water, restores prototype rapidly again after drying and volatilizing, become
Quan Yuan.Therefore the dust heavy workload generated in the water spray anti-Coal Transport of dust suppression, effect are undesirable.
The dust suppressant price of Vehicles Collected from Market quotient is high, and without dedicated automobile coal transportation dust-depressor.Develop a kind of public affairs
The defeated New Dust-Depressor of road transport is imperative.
Summary of the invention
To solve technical problem of the existing technology, the present invention provides one kind can effectively inhibit dust, have at
Film thickness, solid highway coal transportation dust-depressor that dirt is strong, waterproof performance is good and preparation method thereof.
To achieve the above object, the technical scheme adopted by the invention is as follows a kind of highway coal transportation dust-depressor, according to
Lower parts by weight are matched, 10-20 parts of high hydroscopic resin, 3-8 parts of gypsum, 6-15 parts of polyacrylamide, polymer dispersion powder 15-
30 parts, 40-60 parts of urea.
Preferably, matched according to following parts by weight, 15 parts of high hydroscopic resin, 5 parts of gypsum, 10 parts of polyacrylamide,
25 parts of polymer dispersion powder, 55 parts of urea.
A kind of method for being used to prepare highway coal transportation dust-depressor, follows the steps below operation,
A, gypsum, urea are first ground to 100-150 mesh；
B, polyacrylamide, dispersibility latex powder are heated to 35 DEG C -40 DEG C, be sufficiently dried again；
C, it mixes: the gypsum prepared, urea, polyacrylamide, dispersibility latex powder being successively added into reaction kettle
And high hydroscopic resin, it stirs；
D, mixed powder is added water and stirred 15 minutes according to the ratio of 1:100-1:150, being then allowed to stand half an hour goes out
Kettle packaging.
Preferably, the mixing speed in the step c is 3000 revs/min.
Compared with prior art, the present invention has following technical effect that the present invention mainly uses hydroscopic high-molecular resin, gathers
After acrylamide, urea, gypsum are mixed with dispersed rubber powder by certain configuration, tap water is added to be mixed into certain density liquid
Body is sprayed on automobile loose unpacked material, it can form a kind of shell membrane substance by dust, particle mutually under lock and key, have at film thickness,
Gu the features such as dirt is strong, waterproof performance is good, green, environment-friendly degradable, can effectively prevent particle, dust to drift and migrate, be one
Kind Automobile Transportation logistics can be prevented to be scattered, prevent fugitive dust, and can reduce transport Coal Logistics loss, reduced and be lost, saving at
This.
Specific embodiment
In order to which technical problems, technical solutions and advantages to be solved are more clearly understood, tie below
Embodiment is closed, the present invention will be described in further detail.It should be appreciated that specific embodiment described herein is only used to solve
The present invention is released, is not intended to limit the present invention.
Embodiment one
