Description
Technical field
The present invention relates to the technical fields of solid dust agent, and in particular to a kind of green dust agent and preparation method thereof admittedly.
Background technique
Treating flour dust is an important topic of current atmospheric prevention and cure of pollution, and many dust problems all originate from anthropogenic discharge,
Such as construction dust from construction sites, mining fugitive dust, road transport fugitive dust, industrial production fugitive dust.
It is current most common, the simplest dust removal method that waterpower depositing dust, which consolidates dirt, but the surface tension of water it is big, to dust
Effect of impregnation is poor, and volatile, therefore by sprinkling water, solid dirt efficiency is lower and action time is very short merely, it is difficult to full
The needs of the current environmental protection of foot.
In recent years, various countries achieve many progress in terms of solid dust agent, but these products have difficult drop in various degree
Solution, at high cost, secondary pollution problems.CN200810057756.4 prepares solid dust agent by primary raw material of silica gel, and silica gel is in original
For ratio in material 80 or more percent, this method is primarily present the difficult problem of degradation；CN201010204156.3 is with height
Molecule synthesis water-soluble polymer, propylene glycol phenylate, polyvinyl alcohol, ammonium polyacrylate salt and water prepare dust suppressant, and this method is deposited
The secondary pollution the problem of；CN201210329645.0 is with sodium hydroxyethlcellulose, carboxylic propyl sodium starch, hydrogen peroxide, glycerol, chlorine
Change calcium, sodium fluoride, dibutyl phthalate, bentonite and water and dust suppressant is made, complex process equally exists secondary pollution and asks
Topic；CN201110160998.8 prepares dust suppressant with natural emulsion, natural plant fibre, glycerine, surfactant and water, at
This is higher, equally exists problem difficult to degrade；CN106350014A is with hydrolyzed animal protein, lauryl sodium sulfate, ethoxy
Cellulose, silicone resin polyethers lotion etc. are made dustfall agent, and this method has complex manufacturing process, at high cost.
Summary of the invention
In order to solve the above problems existing in the present technology, the present invention provides it is a kind of it is environmentally protective, be easy to degrade, environment
The strong green of friendly, solid dirt ability consolidates dust agent and preparation method thereof.By adjusting the sulphur oxygen ratio in the rare-earth oxide sulfate,
The colorant of different colours can be obtained.The solid dust agent of green is with improved plant polysaccharide compound (pre-gelatinized starch, paste
Essence, xanthan gum, cellulose ether derivatives compounding mixture) be primary binder, adhesive supplemented by plant disaccharide (sucrose)
Aqueous solution；The solid dust agent takes full advantage of the colloid property of plant polyose, can be formed between dust and soil particle stable
Multiple spot commissure reticular structure is captured and is fixed to dust and the efficient of soil to realize；The solid dust agent is green safe, environment
Close friend, preparation is simple, easy to use, can meet the solid dirt needs under different condition.
The technical scheme adopted by the invention is as follows:
A kind of solid dust agent of green, raw material components include:

The cellulose ether derivatives are carboxymethyl cellulose, hydroxypropyl methyl cellulose, hydroxyethyl cellulose, hydroxypropyl
The mixture of one or more of base cellulose.
A method of the solid dust agent of the green is prepared, is included the following steps:
(1) it successively takes pre-gelatinized starch, dextrin, xanthan gum, cellulose ether derivatives, sucrose, be sufficiently mixed uniformly, obtain
To mixed powder；
(2) add water into the mixed powder, stirring mixes them thoroughly uniformly to get the solid dust agent of the green.
In step (1), 80 mesh of partial size < (0.175mm) of the gelatinized starch, viscosity > 300mpas；The dextrin
DE value 15-19%, solubility > 98%；80 mesh of partial size < (0.175mm) of the xanthan gum, viscosity > 1200mpas；
80 mesh of partial size < (0.175mm) of the cellulose ether derivatives, viscosity > 600mpas.
In step (2), the temperature for carrying out the stirring is 15-60 DEG C, and the time for carrying out the stirring is 45-120min；
The rate for carrying out the stirring is 60-180rpm.
The invention has the benefit that
The solid dust agent of green of the present invention, it is derivative by using precuring starch, dextrin, xanthan gum, cellulose ethers
Object, sucrose, water are raw material and carry out weight proportion appropriate, and the green being finally prepared consolidates dust agent, with pre-gelatinized starch, paste
Essence, xanthan gum, cellulose ether derivatives compounding mixture be primary binder, adhesive supplemented by sucrose, take full advantage of plant
The colloid property of object polysaccharide can form stable multiple spot commissure reticular structure between dust and soil particle, to realize to powder
Dirt and the efficient of soil capture and fix；It has the advantage that as follows: (a) by the infiltration of the plastic characteristic of plant polyose and plant disaccharide
Characteristic organically combine, can upper soll layer form a film while quickly permeate downwards, formed outside soil it is stable, have it is higher
Intensity, continuous cured layer, can effectively fixing soil and dust granule, efficiently inhibit fugitive dust；(b) formed cured layer has
Good stability, and have certain abrasion resistance, Gu dirt effect is good, Gu the dirt period is long, can meet exposure, high temperature, rainfall,
Solid dirt under the varying environments such as high wind needs, and consolidates dirt test by the wind regime under 6-8 grades of wind conditions；(c) all formulas are set
Meter is considered using environmentally protective as premise, therefore Product Green safety, environmental-friendly, pollution-free, not will cause " secondary dirt
Dye "；(d) construction is simple, operation is convenient, can meet the needs of the different solid dirt environment such as site construction, mine, industry manufacture；(f)
Manufacturing cost is low, and preparation process is simple, easy to industrialized production and large-scale promotion.
