Abstract
The invention relates to an organic/inorganic composite environment-friendly snow melting agent. The snow melting agent comprises 30 to 90 parts of formate, 25 to 75 parts of nitrate, 0.5 to 10 parts of sulfate, 0.5 to 15 parts of acetate, 1 to 20 parts of urea and 5 to 25 parts of calcium carbonate. The snow melting agent has a high snow melting speed and a good effect. Compared with the traditional chloride snow melting agent, the snow melting agent has low corrosivity on roads and bridges and low harmfulness on plants. Compared with the traditional calcium magnesium acetate snow melting agent, the snow melting agent is relatively low in cost. A preparation method for the snow melting agent is simple and practicable and applicable to large-scale mechanized operation, and has high popularization and application prospects.
Description
Technical field
The present invention relates to the friendly type Snow Agent in a kind of organic-inorganic complex loop border, be specifically related to a kind of with the reasonable composite environment friendly type snow melt agent that forms of components such as formate, nitrate salt, urea.
Background technology
The snowfall of cold district has brought very big inconvenience for people's life and trip, and very easily brings out traffic hazard, and especially on motorway, also might freeze because of accumulated snow or snow melt stops transport the compelled sealing of motorway, causes great financial loss.Therefore, how fast snow removing is antifreeze, ensures that highway is unimpeded fast, has important economic implications and social effect undoubtedly.
Present snow-removing method mainly contains artificial the snow removing, snow removal with machine and Snow Agent snow removing three major types, but artificial snow removing and snow removal with machine efficient are lower, and be difficult to remove totally, stay residual snow and can freeze once more at low temperatures.The Snow Agent that spreading is an amount of can be removed the accumulated snow on the highway apace, and ice and snow is thoroughly melted neatly, has become indispensable part in the antifreeze work that removes the snow in the winter time, plays an important role.
Snow Agent commonly used is a villaumite, and particularly sodium-chlor reduces good, the ample supply and prompt delivery, cheap of freezing point performance; But villaumite has corrodibility to concrete and metal; Plant and soil are had hazardness, when thawing ice and snow, subgrade and pavement, greening, vehicle etc. are all caused damage.For this reason, people add " inhibiter " in the villaumite Snow Agent, though suppressed corrosion to a certain extent, still have higher chlorine ion concentration.Mostly inhibiter is nitrite, can only be used for Reinforced Concrete Bridge, and in case infiltrates soil meeting polluted underground water.And traditional environment-friendly snowmelt agent is staple with the calcium acetate magnesium salt, though have characteristics pollution-free, environmental protection, the deicing effect is influenced by environmental temperature, and snow melt efficient is lower, and it costs an arm and a leg, general only on the airport, important place such as large-scale square uses.Therefore develop environmental protection, efficient, the significant and application and popularization value of novel Snow Agent that price is suitable.
Summary of the invention
The present invention provides a kind of organic-inorganic complex loop border friendly type Snow Agent.Snow Agent of the present invention is by reasonable composite the forming of components such as formate, nitrate salt, urea warp.Snow Agent staple of the present invention have cost low, biodegradable, little to concrete in the highway foundation facility and corrosion of metal property, basically soil and water source such as are not polluted at advantage.
Environment friendly type snow melt agent according to the invention, its essentially consist and mass fraction are:
Formate is a kind of of sodium formiate, potassium formiate or their mixture.Nitrate salt is a kind of of SODIUMNITRATE, nitrocalcite, magnesium nitrate, saltpetre or their mixture.Vitriol is a kind of of sodium sulfate, vitriolate of tartar or their mixture.Acetate is a kind of of sodium-acetate, Potassium ethanoate, calcium acetate, magnesium acetate or their mixture.
Except said components, Snow Agent of the present invention can also contain Snow Agent field other various supplementary additives commonly used.
The present invention also provides the preparation method of above-mentioned Snow Agent: formate, nitrate salt, vitriol, acetate, urea are tentatively mixed in said ratio; To just mix thing then pulverizes and sieves through kibbler; Again with enclose in the Plastic film Bag immediately behind the calcium carbonate granule thorough mixing; Add woven bag and seal, promptly make Snow Agent of the present invention.
Snow Agent of the present invention can solve traditional Snow Agent and be used for the problem that the road snow removing is produced.Snow Agent of the present invention does not contain villaumite, is beneficial to environmental protection; Compare with calcium acetate magnesium salt, snow melt speed is fast, snow melt is effective, and price is relatively cheap; Preparation technology is simple, is applicable to that mass mechanized manipulates.
