Description
Technical field
The invention belongs to the dust suppression technologies in environment protection field.In particular it relates to a kind of dust suppressant, especially
Ground is related to a kind of rain-proof crust dust suppressant and its application method.
Background technique
With the industrialization of human society, the quickening of urbanization process, urban sprawl, mineral exploration and exploitation are reclaimed wasteland et al.
Class activity produces a large amount of exposed soil side slope, outdoor mineral reserve, abandoned mine, powder stockyard, and exposed soil and powder stockyard are by wind
Will dust fly upward, put to no little inconvenience to the living trip of resident, while also will form the pollutants such as fugitive dust, particulate matter, shadow
Ring the health of resident.At present for the exposed earthwork, industrial and mineral stock ground such as building soils, some is hidden using non-woven fabrics or sunshade net
Lid, encounters strong wind weather fugitive dust and still remains；Use water spray dust's measure also, after moisture is evaporated quickly, dust continues
It flies upward.
At present for exposed accumulations of the earthwork such as building soils, generallys use following several method and solve: one, sprinkling water.Building
The fugitive dust problem in the regions such as building site, road, coal mine, rickyard can be alleviated with watering, but moisture will soon steam
Hair, dust can wave with the wind again, then proceed to watering dust prevention.In cycles, if things go on like this, a large amount of water resource is consumed.Two,
Cover Air Filter.Air Filter can weaken wind-force, reduce the Dust Capacity being blown up, and can play a degree of dust-proof work
With, but drawback is also apparent from.Firstly, reply bad weather ability is poor, wind-force reaches 6 grades or more and just loses dust-proof effect substantially.
Secondly, breakage easy to aging after being irradiated for a long time by sunlight, the Air Filter after breakage performs practically no function, and does not have dustproof effect not only, and
And be easy to be blown off and can not recycle by strong wind, still landfill disposal is either blown off by wind after aging is damaged, is caused secondary
Pollution.And Air Filter is non-watertight, meets with rainwater and easily generates runoff, leads to soil erosion even landslide.
Chinese patent CN109609094 discloses a kind of crustization agent, using farinose as adhesive, but both
For material after forming shell, cohesive force is poor, is easy to be smashed when rainy by rain drop erosion or dispelled by high wind, shell is held time
It is shorter, and farinose etc. cannot be directly dissolved in water, need to dissolve using glycerol as solvent, liquid composition leads to it not
Convenient for storage transport, glycerol has certain risk, is not easy to preservation.
Summary of the invention
To overcome technological deficiency of the existing technology, the invention discloses a kind of rain-proof crust dust suppressant and its users
Method.
Rain-proof crust dust suppressant of the present invention, is made: 10~50 parts of adhesive, high score of the component of following portions by weight
1~10 part of sub- film forming agent, 5~30 parts of dispersing agent, 1~10 part of waterproofing agent;The adhesive is fenugreek gum, sesbania gum, gelatin
One or more of.
Specifically, the macromolecule film former is polyvinyl alcohol, polyvinyl butyral, hydroxypropyl methyl cellulose, shell
One or more of glycan, carboxymethyl cellulose.
Specifically, the dispersing agent is one or more of sodium chloride, potassium chloride, magnesium chloride.
Specifically, the waterproofing agent is one or more of organosilicon, multi-component copolymer waterproofing agent.
Preferably, further include 1~15 part of toner, the toner be one of pre-gelatinized starch, glutinous rice starch or
It is several.
It preferably, further include toner, the toner is one or more of iron oxide green, iron oxide yellow, iron oxide black.
It preferably, further include 1-4 parts of crosslinking agents, the crosslinking agent is organosilicon cross-linking agent, in borax, boron zirconium crosslink agent
It is one or more of.
The application method of rain-proof crust dust suppressant of the present invention are as follows: mixed by the 0.5%~4% of aqueous solution total weight with water
Stirring, standing 10-30 minutes after mixing evenly dissolves it sufficiently, then uniformly sprays dust suppression agent solution by the amount of 0.5~3L/ ㎡
It is sprinkled upon subject surface.
Using rain-proof of the present invention crust dust suppressant, have the following advantages:
1. compared with prior art, rain-proof crust dust suppressant of the present invention, raw material are non-toxic, pollution-free, degradable
Substance not will cause secondary pollution.
2. shelling can be consolidated without rainfall within 2~4 hours summers, 12~24 hours winters after present invention sprinkling, formed
Crust layer.In the case that no external force is destroyed, crust layer can keep out the erosion of 8 grades of strong wind and moderate rain or heavy rain.
3. of the invention using easy to operate, construction is can be completed in 1~2 people, is destroyed if crusting after construction by external force
Failure, can fill spray reinforcing at any time, and maintenance is simple.The present invention once spray construction after without mechanical external force destroy in the case where can keep
4~6 months, 6~12 months can gradually natural degradation, be not required to artificial treatment, into can also form nutrient needed for plant in soil,
Conducive to plant growth.
Specific embodiment
Specific embodiments of the present invention will be described in further detail below.
Rain-proof crust dust suppressant of the present invention, 10~50 parts of adhesive, 1~10 part of macromolecule film former, dispersing agent 5~
