Abstract
The present invention provides a kind of high efficiency road deicers and preparation method thereof, the deicer comprises the following components in parts by weight: 0.1-1 parts of polyethylene oxide, 0.2-0.3 parts of potassium acetate, 100-150 parts of plant ash leachate, 2-5 parts of emulsifier, 0.3-0.5 parts of sodium citrate, 0.02-0.05 parts of 2-mercaptobenzothiazole, 0.01-0.03 parts of poly (sodium aspartate), 0.2-0.4 parts of sodium tetraborate, 0.4-0.6 parts of sodium lactate, 0.3-0.6 parts of dicyclohexyl amine nitrite, 3-5 parts of diatom mud dry powder；Deicer is prepared by the methods of dissolution, stirring, heating, multigelation, deicer of the present invention is with sylvite for main deicing component, chloride ion without corrosion metal, it also can effectively prevent corrosion of the deicer to metal and road surface while efficient deicing, and ice and snow dissolve after destruction of the water containing deicer to vegetation, be a kind of energy saving and environment friendly efficient deicer.
Description
Technical field
The present invention relates to road deicing agent technical fields, and in particular to a kind of high efficiency road deicer and preparation method thereof.
Background technique
Winter Snow is a kind of common natural phenomena, however some local temperatures are lower, and road snow is difficult to melt, road
The accumulated snow on road is after vehicle is compacted, and the frictional force on wheel and road surface reduces, the easy left and right sliding of automobile, meanwhile, the braking of automobile away from
From being also difficult to control, once speed is too fast, turning is too anxious, traffic accident may all occur, even if accumulated snow is sunny at noon
When melt, build-up ice also due to temperature is too low, complicated weather condition has seriously affected the situation on road surface, accumulated snow, frost
Freeze, thin ice situations such as happen occasionally, bring huge risk to vehicle driving, it is unimpeded not only to seriously affect urban transit system, and
And traffic safety is influenced, or even cause the heavy losses of national wealth and people's lives and properties.Therefore, advanced technology means are taken
It realizes actively anti-icing, dedusting, ensures the urban transit system safety under ice and snow bad weather, especially guarantee city viaduct, overhead
Bridge up and down the traffic safety of key nodes such as ring road with it is unimpeded, it has also become realistic problem in the urgent need to address.Currently, for height
The deicing measure on the ground such as fast highway, airfield runway, bridge and urban road mainly has snow removal with machine, artificial snow removing and deicer to remove
Snow.Since large-scale snow removing equipment more lacks, the speed that removes the snow and efficiency are lower for snow removal with machine.When artificial snow removing, peace is had often
Full accident occurs, while large labor intensity, influences traffic circulation order and speed.Therefore, domestic and international more options it is time saving, it is laborsaving and
The deicer snow removing mode that sudden hurt accident can be made to reduce.
Deicer is dredged convenient for road by reducing the accumulated snow on ice dissolution temperature thawing road, it is bright to sow place's effect
Aobvious, common deicer is with " villaumite " for main component, such as sodium chloride, calcium chloride, magnesium chloride, potassium chloride, but it has
Harmfulness uses the accumulated snow after deicer although price is also cheap the study found that chloride salt deicer is convenient for deicing, snow melt
It is usually deposited in greenbelt or the farmland of road both sides, its esters residue is all deposited in farmland and greenbelt after the beginning of spring,
Make the salinization of soil, destroy vegetation, crops and trees are afraid of salt, will cause green plants mortality, and harm is even ruined
Going out property, even if after-culture again, also want whole soil removal and replacement, farmland is just more doomed, loses self-evident and such
The residue of villaumite deicer can also corrode road surface and automobile rubber tire.
106318319 A of patent of invention CN discloses a kind of novel deicing aerosol, includes: ethylene glycol, polyethyleneglycol
Methyl ether, neopelex, fatty glyceride, fatty alcohol polyoxyethylene ether, p-methyl benzenesulfonic acid, isopropanol, three ethyl alcohol
Amine, the various ingredients such as deionized water, but it is of limited application, and the effect for melting ice sheet is general, cannot remove road well
On icing.In addition, 103805139 A of patent of invention CN discloses a kind of deicing aerosol, by ethyl alcohol, sodium tetraborate, peppermint
Alcohol, triethanolamine, sodium sulphate, propellant, xanthan gum, the raw materials such as distilled water are made, and made deicing spray can not rise
To ice action is preferably removed, application is also limited.

Moisture dissolution in gas, accelerates ice-melt speed.
For deicer of the present invention with sylvite for main deicing component, the chloride ion without corrosion metal effectively prevent deicer
Destruction of the water containing deicer to vegetation after corrosion and ice and snow to metal and road surface are dissolved.
The polyethylene oxide powder described in the step a of preparation at normal temperature can arbitrary proportion be dissolved in water, therefore by its
It is directly dissolved in plant ash leachate, mixed liquor at this time is viscous liquid, carries out adequately stirring vibration, adds in step b
Enter emulsifier, to reduce the viscosity of mixed liquor, convenient for the preparation of the deicer, while potassium acetate, sodium citrate, four is added
Boratex and sodium lactate improve ice-melt rate, and dispersion each component is accelerated in the stirring of edge height temperature side, and carrying out ultrasonic vibration makes it
Uniformly；Step c joined diatom mud dry powder during preparing corrosion inhibiter powder, increasing temperature stirs evenly it faster；Step
The rapid longer mixing time of e is uniformly dispersed so that each component comes into full contact with, and the deicer finally prepared is more efficient.
The deicer surface being attached to after polyethylene oxide is dry, forms layer protecting film, has stronger adsorption capacity,
Make deicing substance be not easy to be fallen by rain drop erosion, while its long-acting deicing can be promoted with the ice-melt substance that absorbed portion releases
Deicing reduces costs to reduce the usage amount of deicer, more reduces environmental pollution.
Plant ash leachate, main component are sylvite, can be improved ice-melt speed, nontoxic, and contain iron, magnesium
Etc. various trace elements, root growth can be promoted, there are also the effect for mitigating pest and disease damage, a large amount of potassium ion in plant ash, energy
The intensity for effectively weakening fruit tree leaf transpiration water, enhances tree body drought resisting, high-temperature resistance, may additionally facilitate the fortune of carbohydrate
Turn, improves disease-resistant, the insect resistance capacity of tree body.
The molecular porous structure of diatom ooze itself, porosity are up to 90%, and specific surface area is up to 65m2/ g has very strong
Water absorbing capacity, with polyethylene oxide, plant ash synergistic effect after can effectively solve the problem that ice and snow on road surfaces melt after ponding problem.
2-mercaptobenzothiazole, poly (sodium aspartate) and dicyclohexyl amine nitrite synergistic effect be able to suppress metal product and
The corrosion of concrete can protect the destruction of not de-iced dose of road surface, extend the service life of road.
Deicer of the present invention can efficient deicing, in addition to the use for having saved deicing agent material, at the same save
The consumption of the energy in ice detachment, belongs to environmentally friendly deicer, is suitable for a wide range of promote.
