Description
Technical field
The present invention relates to a kind of dust suppressants and preparation method thereof, more particularly, to a kind of outdoor dump coverture of natural environmental-protective
Preparation method.
Background technique
For a long time, coal is occupied an leading position always in the production and consumption structure of China's energy as basic resource.
It is predicted according to relevant expert, to the year two thousand fifty, specific gravity of the coal in China's non-renewable energy, which is thrown away, will occupy 50% or more.Since China is existing
Stage economic situation and basic condition are determined that the coal storage that China produces at present is most to use air storage, coal
Charcoal occupied area is wide, and when being acted on by natural conditions such as wind-force, heap coal yard can generate a large amount of coal dusts, pollutes working environment, and
Most coal dusts belong to respirable dust particle, and respirable dust, which enters human body, can cause human lung's lesion, due to for
Timeliness that dust is done harm to huamn body and insufficient, operation work in such a case for a long time is recognized the potentiality that production threatens
Make, worker extremely agrees that silicosis can be obtained, and health is seriously damaged.According to investigations, caused by all because of various dust
In Pneumoconiosis Cases, the specific gravity that coal miner accounts for is maximum.
Traditional physics dump depositing dust is mainly the generation that dust is regularly reduced to dump water spray or paulin covering method,
But the anti-evaporating performance of water is poor, needs continuous spray water, causes the waste of water resource；Tarpaulin covering method is suitable for some small
The dump of type, for big dump, operating difficulties needs a large amount of manpower, and the uvioresistant of tarpaulin is poor, needs often more
It changes；More and more scholars studied wind screen to inhibit the generation of dust in recent years, mainly passed through the wind direction of control incoming flow wind
The generation of dust is reduced with wind speed, but wind screen cost of investment is big, and has a single function, dust suppression rate is low.Pressed down based on tradition
The deficiency of dirt measure has been the direction of outdoor Coal Stack Yard dust controlling research using chemical dust suppressant.
Dust suppressant type currently on the market is more, but has the disadvantage that: 1) preparation process is cumbersome, improve its at
This；2) viscosity number of product solution is too big, easily blocking spray head；Viscosity is too small, and solution is extremely easy to prolong due to gravity
Dump low side is flowed to, causes the thin lower end in dump cured layer upper end thick, that is, influences the intensity of cured layer, and cause the wave of solution
Take；3) not degradable, cause secondary environmental pollution；4) water-resistance is poor, after undergoing the rainy day, dries again, formation is solidified into
Resisting wind erosion is poor, influences anti-dust effect；5) high and low temperature resistance is poor, cured layer experience high temperature ultraviolet line or cryogenic freezing after,
Cured layer intensity is lower, and wind resistance effect is deteriorated.
Summary of the invention
The purpose of the present invention is in view of the above problems, providing a kind of preparation side of dedicated coverture for outdoor dump
Method, the dedicated coverture can be uniformly sprayed on dump surface, the cured layer with some strength be formed after 4h, and solidify
The thickness of layer is uniform, has good elasticity, can effectively prevent coal dust floating under the action of the wind and pollutes ring in air
Border solves the problems, such as Coal Loss and pollution environment and harmful to human health.It is simple to cover agent solution preparing process, at
This is low, can be biodegradable, the not influence of climate condition.
Above-mentioned purpose is achieved through the following technical solutions: the outdoor dump coverture of natural environmental-protective, and formula includes as follows
Mass percentage composition:
Preferably, it is made of following mass fraction:
Preferably, the binder is selected from one of Sodium Polyacrylate, polyacrylamide, sodium alginate or a variety of polymerizations
Object.
Preferably, the film forming agent is sodium carboxymethylcellulose, in sodium carboxymethylcellulose pyce, polyvinyl alcohol, sodium alginate
One or more mixtures.Preferably, the crosslinking agent be one of polyethylene glycol, glycerine, sodium chloride, aluminium chloride or
A variety of mixtures.
Preferably, the surfactant is fatty alcohol polyoxyethylene ether, lauryl sodium sulfate, octadecyldimethyl
One of glycine betaine or a variety of mixtures.
In the present invention, binder and film forming agent are high molecular polymer, these substances form net under the action of crosslinking agent
Shape structure enhances the stability of the product, and the cured layer for being sprayed at the formation of dump surface has certain toughness and intensity, tool
There is preferable anti-dust effect.
Beneficial effects of the present invention are as follows: in laboratory conditions, it is 15cm, the circle of a height of 5cm that coal dust, which is piled diameter,
Cone-shaped after spraying the coverture with the amount of 2Kg/m3, is formed on its surface one layer of complete cured layer, the thickness up and down of cured layer
Degree uniformly, for 3-5mm, avoids the too small low side that is cast to of solution viscosity and causes tip thickness small, the big phenomenon of low side thickness.It should
Cured layer is after multiple high/low temperature, then carries out weather-proof experiment, and crack does not occur in surface.And resistance to compression reality is carried out to it
Detection is tested, with the cured layer on pressure gauge pressing dump surface until skin breakage, compression strength 40-50KPa.Sprinkling covering
The dump of agent continuously resists after blowing 2h, surface does not rupture, and weather-proof rate reaches 99.8%, dust suppression under conditions of wind speed is 15m/s
Effect is good.Natural environmental-protective coverture spray solution of the invention can generate the high cured layer of compression strength to dump surface, and anti-
Answer temperature in room temperature, it is at low cost, it is without secondary pollution.
Specific embodiment
In specific implementation below, binder be selected from one of Sodium Polyacrylate, polyacrylamide, sodium alginate or
Multiple polymers, preferably Sodium Polyacrylate；Film forming agent is selected from sodium carboxymethylcellulose, sodium carboxymethylcellulose pyce, polyvinyl alcohol, seaweed
One of sour sodium or a variety of mixtures, preferably carboxymethyl cellulose sodium；Crosslinking agent is selected from polyethylene glycol, glycerine, chlorination
One of sodium, aluminium chloride or a variety of mixtures, preferably polyethylene glycol；Surfactant be selected from fatty alcohol polyoxyethylene ether,
One of lauryl sodium sulfate, octodecyl betaine or a variety of mixtures, preferred fat alcohol polyoxyethylene
Ether.
When coverture sprays, dump surface is uniformly sprayed at by the amount of 2Kg/m3.
