Description
Technical field
The present invention relates to a kind of Snow Agent, particularly a kind of environment protection snow-dissolved agent and preparation method thereof.
Background technology
The snowfall in winter has caused great inconvenience for the China and the traffic and transportation system of other countries in the world, causes road block, and traffic hazard increases, and when snowfall is big even compelled closing high-speed highway, has seriously restricted the traffic and transportation system normal operation.Snow removing work behind the snow becomes the key that ensures that traffic and transportation system runs well.Present snow-removing method mainly contains artificial snow removing, snow removal with machine and Snow Agent snow removing three major types, but artificial, snow removal with machine efficient is lower, the consumption human and material resources are bigger.For ease, fast, snow removing efficiently, the mankind bring into use Snow Agent snow removing.At present to be mainly chloride salt be two or three mixture in sodium-chlor, magnesium chloride, the calcium chloride to the Snow Agent used of road; But the chloride salt Snow Agent causes serious corrosion to road, bridge and automobile chassis; Cause salt damage with farm crop and green plants, thereby cause enormous economic loss the road both sides.As the countermeasure that solves, people add various inhibiter like silicates, phosphoric acid salt, tartrates etc. in Snow Agent.Like Granted publication number is the Chinese patent of CN1242016C.This patent is in the inorganic salts Snow Agent, to have added the rust-preventive agent Starso; Though the adding of these inhibiter has suppressed corrosion to a certain extent; But because of their particle diameter less; Mix different substances together the back with Snow Agent and be prone to layering takes place, reduced the snow melt effect and can not evenly cause corrosion mitigating effect undesirable by thorough mixing with Snow Agent.Non-chloride salt Snow Agent such as CMA though environmental protection costs an arm and a leg and freezing point is lower, have limited its use range greatly.Granted publication number is the Chinese patent of CN 1657586C, though this patent changes the cost that working method has reduced CMA, realizes turning waste into wealth also difficult and traditional Snow Agent competition on the price.Publication number is the one Chinese patent application of CN1648192A, and disclosed environment protection snow-dissolved agent in use produces deposition, and on the road surface, this not only influences the snow melt effect, and the cleaning of returning road brings difficulty; In addition, be acid, can shorten the work-ing life of road with the solution after this Snow Agent snow melt.Because the cost on Ordinary Rd, motorway, airport is with different to the corrosive requirement, it is extremely urgent to develop snow melt speed environment-friendly snowmelt agent fast, moderate, environmentally safe.
Summary of the invention
The objective of the invention is to overcome the defective of prior art; A kind of environment protection snow-dissolved agent and preparation method thereof is provided; This environment-friendly snowmelt agent has characteristics such as low price, pollution-free, no burn into are easy to use, suitable for mass production, is applicable to that different kinds of roads and bridge, airport etc. need the occasion of snow removing.
The present invention seeks to realize through following technical scheme:
A kind of environment protection snow-dissolved agent mainly is made up of magnesium nitrate and sodium acetate.

(1) the A3 steel disc is bright with the polishing machine polishing, to remove the virgin metal surface layer, the quick water of steel disc that polishing is good, magnesia powder paste etc. fully deoil and wash, then with ketone, alcohol flushing.Put into moisture eliminator after the drying rapidly, the placement room temperature is surveyed its area, weight and is numbered one by one.
(2) in 12 beakers, add 300 ml distilled waters respectively, wherein 3 beakers add sodium-chlor 30 grams, are divided into three groups at other 9 beakers, and every group of Snow Agent 30 grams that add respectively by embodiment 1-3 promptly are made into concentration and are 10% solution.
(3) steel disc of step (1) being handled is suspended in the solution for preparing with nylon rope respectively, makes steel disc be in the position of solution lower middle.
(4) with steel disc successive soaking 24 hours in solution, take out the back and falls steel disc surface iron rust with brush, use alcohol, acetone rinsing then, put into moisture eliminator after the rapid drying, weigh one by one.Snow Agent is as shown in table 2 to the Corrosion rate in Carbon Steel experimental result.
Table 2
Can find out that from last table Snow Agent of the present invention is about half of sodium-chlor depth of corrosion than low mostly of sodium-chlor average corrosion depth, and is suitable with the average corrosion depth of pure water.
Test of the infringement test of 3 Snow Agent of the present invention to plant
Snow Agent of the present invention and sodium salt have carried out toxicity test to the lawn, and experimental period is elected the early spring as, and this moment, little grass was more tender and lovely relatively more responsive to toxic substance.Experiment content: be dissolved in 1 premium on currency with 20 gram sodium-chlor with by the Snow Agent that embodiment 1-3 processes respectively, evenly be sprayed at 300 * 300mm (0.09m
2) the lawn on, the sprinkling amount is about 200g/m
2The obvious flavescence in little careless tip after five days in the lawn of spraying sodium chloride solution; Spray in the lawn of this Snow Agent solution little grass with spray before do not change; The little careless big area of spraying after one month in the lawn of sodium chloride solution is dead, and the little careless growing way of spraying in the lawn of this Snow Agent solution is luxuriant.
Test the corrosion experiment of 4 Snow Agent of the present invention to the concrete road surface
Using the Snow Agent of processing according to embodiment 1-3 to be made into concentration respectively is 20% solution, and concrete test block has been carried out corrosion experiment, and soak time is 240 hours, soaks the back concrete blocks and does not have considerable change.Loose phenomenon appears in the concrete test block surface that the sodium-chlor of employing same experimental conditions soaked, and has very strong corrodibility.
Test the experiment that 5 Snow Agent of the present invention use the back surface friction coefficient to change
This experiment is equipped with the slide block simulation actual wheel of rubber tyre and the friction condition of ice face with the bottom; Water in the concrete road surface and to process real ice face; Under-10 ℃ of conditions, measure the frictional coefficient of glare ice face earlier, evenly sprinkle 10 gram Snow Agent of the present invention and sodium-chlor more successively; The result shows, is sprinkled into the frictional coefficient on road surface after the Snow Agent of the present invention and improves 60% and 40% respectively than the frictional coefficient of glare ice face, the frictional coefficient that is sprinkled into the road surface of sodium-chlor.
