Description
Technical field
The present invention relates to dust-proof dust suppression technology field, the dust-proof dust suppressant of specifically a kind of humidity-preserving type multipurpose and its work is prepared
Skill.
Background technology
The particle diameter of airborne dust particulate matter is although little, but causes the primary factor of city Particulate Pollution.PM10, PM2.5's
Though particle is little, specific surface area is big, is vulnerable to various pollutions, is more easy to accumulate a large amount of harmful elements, is detrimental to health.It is outdoor to adopt
Ore deposit and stockyard, construction site airborne dust, construction material stockyard, desert etc. be all produce dust main place, be world's public hazards it
One.With taking place frequently for the pollution problems such as mist thunderbolt, affected area is more and more, badly influenced people normal life and
It is healthy.10 mouthfuls of September in 2013, State Council prints and distributes《Prevention and control of air pollution action plan》Notice.Specify that and refer specifically to
" by 2017, national region above city inspirable particle concentration declined 10% than 2012 to mark, and very big renovation dynamics is strengthened
Construction fugitive dust is supervised, and actively pushes forward green construction, and wind-proof dust-suppression measure is strengthened in coal yard, stockyard ".Indicate that China's atmosphere pollution is prevented
Control work and the airborne dust dust suppression in construction, coal yard, stockyard is incorporated into emphasis supervision and the scope renovated.
The dust-control method of current various places is basic or watering and covering protection thing etc..Although the method for watering is easy easily
OK, but because the adhesion between airborne dust and moisture is very weak, moisture is easy to evaporation, can not meet the demand of permanently effective dust suppression
Hold time it is short and require to spray frequency it is high, hot weather and drought and water-scarce area are inconvenient to cause dust-proof effect bad and
High cost.The earth material stacked for long-time and a prose style free from parallelism for long-distance transportation play dirt goods and also do not have dust-proof and anti-splash work
With；Dust-proof mode is covered, the secondary utilization rate of conventional Air Filter is low, and degradation speed causes slowly secondary pollution, is also easy to
Damaged using effect is poor, can not solve the problems, such as reentrainment of dust.At present, dust suppressant is more and more studied in China
And application, but still have many incomplete places, urgent need develop it is cheap, it is easy to use, can moistening effect and it is lasting when
Between long, the good dust-proof dust suppressant of humidity-preserving type of dust suppression, solidification effect.
Existing dust-proof dust suppressant, is generally divided into two classes, and a class is the crust type of stockyard (coal yard), railway transportation dust suppression,
The patent No. 20101080552.7《Dust suppressant and its using method》, the patent No. 201310175832.2《Bi-component soaks one pack system
Curing type Coal Transport and storage dust suppressant》Its principle is the shell after surface structure ties 1-2cm, so that wind does not rise
Come, the latter adds the NMFs such as triethylene glycol, but deeper research is not done in intensity；Another kind of is for construction site and road
The wet type dust suppressant on road, mainly makes water be kept for the long period in surface dust by macromolecule moisturizing material, and having reached prevents
The purpose of airborne dust.The patent No. 200610130475.8《A kind of wet type dust suppressant and its production and use》, the patent No.
201210130914.0《Road dust suppressant》、201310194118.8《A kind of Novel environment-friendlyroad road surface dust suppressant》Though emphasis is main
For the dust-proof dust suppression of road, but it is a moisturizing for Main Means, as construction site rolling repeatedly due to Construction traffic, because
This dust-proof time is shorter (most 10 days or so), needs repeatedly to spray, could be in order to be effective.
Therefore, from the point of view of application, it is badly in need of wanting a kind of universal dust-proof suppression as the construction site of Large scale construction
Dirt agent, is easy to construction operation, from performance for, on the one hand can crust, on the other hand need certain moistening effect, it is heavier
What is wanted is to stand rolling back and forth for Construction traffic often to spray without Jing, so as to reduces cost.
The content of the invention
It is an object of the invention to provide a kind of moisture retention is good, surface strength is high, frost resistance good, dust suppression time length, resistance to stone roller
The dust-proof dust suppressant of humidity-preserving type multipurpose of pressure and its preparation technology, to solve the problems, such as above-mentioned background technology in propose.
For achieving the above object, the present invention provides following technical scheme：
A kind of dust-proof dust suppressant of humidity-preserving type multipurpose, is made up of the following raw material according to mass parts：
Another object of the present invention is to provide a kind of preparation technology of the dust-proof dust suppressant of humidity-preserving type multipurpose, comprising following step
Suddenly：
1) deionized water is added in reactor and is heated to 90-100 DEG C, be slowly added to polyvinyl alcohol, sodium metasilicate, fluosilicic acid
Magnesium constant temperature stirring reaction is no less than the 1h times；
2) 60-70 DEG C is cooled to, hydroxypropyl methyl cellulose, lauryl sodium sulfate, ammonium persulfate is added under agitation
Or potassium peroxydisulfate reaction stirring is no less than 0.5h；
3) 35 DEG C are cooled to, alcohol ester 12, ethylene glycol, glycerine, polyacrylamide stirring 0.5h is added, are then filtered,
Obtain finished product.
As further scheme of the invention：Step 1) in, heating reaches 95 DEG C, and the stirring reaction time is no less than 1h, and
For the isothermal reaction time.
As further scheme of the invention：Step 2) in, the temperature of reaction at 65 DEG C, mixing time 0.5-1h.

Application examples 1
In May, 2016, using the dust-proof dust suppressant of humidity-preserving type multipurpose of foregoing invention in the park building of northwest new district
The test applied of earth material stockyard：Test area 5000m2, using dust-proof dust suppressant of the invention according to every square of 0.3kg
Dosage, the dust-proof dust suppressant of common 1500kg fully diluted with the water of 5000kg, diluted while stirring, after stirring 10 minutes,
Equipment is sprayed using vehicular the aqueous solution after dilution is equably sprayed at into windrow surface using spray appliance, per square
About 1kg dilutions are sprayed, the soil layer of top layer about 2cm is immersed.After the 5h times, hence it is evident that visible surface crusts.Keep still after 3 months
Preferably, and solidify after pliability it is good, surface is not slided when moist.Twice heavy rain is not also washed away by rainwater experience, not by big rain shadow
Ring.
Application examples 2
In November, 2015, using dust-proof dust suppressant the applying in the park building of northwest new district of humidity-preserving type multipurpose of the present invention
Work sidewalk carries out road dust Control experiment：Test section width 8m, length 2km.Current vehicle is generally 60-80 ton dregs transportations
Car, bulk cement carrier, reinforcing bar transport vehicle and other Construction traffics, day, traffic volume was more than 500 times.Using dust-proof dust suppressant of the invention
According to the dosage of every square of 0.6kg, the water of dust-proof dust suppressant 9600kg and 32000kg is fully diluted, and is diluted while stirring,
After stirring 10 minutes, equipment is sprayed using vehicular the aqueous solution after dilution is equal in three times every the 3h times using spray appliance
Road surface being sprayed at evenly, making dilution infiltrate into road surface 3-4cm positions, after spraying 10 days, there is certain guarantor on road surface
Humidity, does not occur because rolling the surface dust for causing, it is seen that a part for strong roadbed is defined after solidification.Test is thought：This
