Abstract
A high performance and environment-protective snow-melting agent consists of MEG alcohol powder and/or modified ammonium bicarbonate and/or micro-capsulated percarbide acylamide, associated with water absorbing agent, heating materials, neutralizing agent, anti-skid agent, and corrosion-proof agent, with nano co-crystallizing process, by proportioning, mixing and stirring. It is cheap, easy to be used and no toxicity.
Description
Technical field
The present invention relates to the Snow Agent field.
Background technology
The Snow Agent major ingredient that now uses is villaumite, environmental protection far from, the content severe overweight of chlorine in the snow-broth that melts.It also can corrode vehicle, damage trees, greenery patches and urban operating mechanism and road etc.United States Patent (USP) 3,296,246 reveal a kind of method by starch direct production MEG, but do not relate to the processing and the utilization of mother liquor; Though Chinese patent CN1057052A relates to the method for mother liquor aftertreatment, but be intended to improve the productive rate of major product MEG, the problem of utilizing that does not also relate to mother liquor, the present invention has found the snow melt function of MEG mother liquor, and be main snow melt actives with it, being equipped with other two kinds of existing snow melt abilities has the nanometer DCD modified ammonium bicarbonate and the micro encapsulation percarbamide of heating and function such as anticorrosion again, increase the snow melt ability, improve snow melt speed, adopt nanometer cocrystallization and micro encapsulation new and high technology, made high-efficient environmental protective snowmelting agent.
Summary of the invention
Snow Agent generally must possess three big functional materialss: reduce freezing point material, exothermic material and water-absorbing material.The MEG mother liquor itself is exactly a kind of good reduction freezing point material, water-absorbing material and exothermic material.It is a kind of polyvalent alcohol of uniqueness, is non-reducing grape grain derivative, and it is nontoxic, non-stimulated, biological degradation is fast and thoroughly.PH value is 5-8, belongs to neutral substantially.Unique ring texture makes it can keep the stable and mobile of height.It is composite that principal character of the present invention just is that freezing point material (as alcohol, percarbamide and calcium oxide, modified ammonium bicarbonate), exothermic material (as lime carbonate, iron powder), water-absorbing material (as bentonite and super strength water absorbent) science are fallen in MEG mother liquor and other, makes the nondestructive high-efficient environmental protective snowmelting agent of nontoxic, non-stimulated, no burn into.Feature of the present invention also is when selecting these materials for use, taken into full account their synergy to the snow melt ability.
Embodiment
Illustrate that below in conjunction with embodiment the present invention is achieved in that
One, the snow melt actives of first-selection of the present invention is MEG mother liquor and alcohol synthetic powder (hereinafter to be referred as MEG-alcohol powder), and it can make freezing point be reduced to-25 ℃, and it also is a water-absorbing material simultaneously.Its method for making is:
Embodiment 1:
The raw spirit of 20%-40% weight and the MEG mother liquor dehydrate of 60%-80% weight are added in the kneader, airtight back constantly is being heated to 50-65 ℃ under the kneading, under this temperature kneading 1-2 hour, then under continuous kneading with being cooled to normal temperature in 1-2 hour, stop kneading, discharging is pulverized, and gets MEG-alcohol powder.
Two, another snow melt actives of the present invention's selection is a nanometer DCD modified ammonium bicarbonate, during it is soluble in water, can make freezing point reduce to-10 ℃, and heat absorption when it is dissolved in the water takes place but be mixed with thermopositive reaction, and DCD is again a viscosity modifier simultaneously.Its method for making is:
Embodiment 2:
Accurately take by weighing 200 gram bicarbonate of ammonia and place the 500ml triangular flask, measure 100ml distilled water, after adding the whole dissolvings of 5 gram DCD, the distilled water adding that will contain DCD is equipped with in the triangular flask of bicarbonate of ammonia, stirred 10 minutes with rod, make bicarbonate of ammonia dissolve and quicken as far as possible the association of bicarbonate of ammonia and DCD Hydrogen-bond Cluster.Place the ice groove then, make its decrease temperature crystalline, isolating crystallization at last is exactly modified ammonium bicarbonate.
Three, the present invention has also selected for use micro encapsulation to cross the phosphinylidyne ammonium, and as the snow melt actives, it can make freezing point drop to-10 ℃, it is soluble in water, is dissolved in to be slightly acidic in the water, and it can regulate pH value, the hydrogen peroxide that it contains is a strong oxidizer, can react by promotes oxidn, emits a large amount of heats.It is again a sanitas simultaneously.
Four, the water-absorbing material selected for use of the present invention is wilkinite and super-strong moisture absorbing resin, water-retaining capacity can reach own wt tens to hundred times, and even thousands of times.
Five, the exothermic material selected for use of the present invention is iron powder, ferric sulfate lime carbonate and calcium oxide etc., their heat releases when contacting with water with oxygen.Iron powder is again the catalyzer that percarbamide decomposes thermopositive reaction.
Six, the preparation of Snow Agent
The three big functional materialss that Snow Agent has been arranged also must add some auxiliary materials, as neutralizing agent, sanitas, viscosity modifier etc., just can prepare the Snow Agent of excellent property.Because of the difference of environment for use, application scenario, application process, particularly avenge the difference of condition, the prescription of Snow Agent should be formulated as the case may be, can only provide the approximate range of each consumption of main materials here:
Three kinds of main snow melt activess: MEG-alcohol powder, nanometer DCD modified ammonium bicarbonate, micro encapsulation are crossed the phosphinylidyne ammonium, can select wherein a kind of, two or three all use: account for 20%-50%;
Water-absorbing material (super strength water absorbent, wilkinite): account for 0.1%-50%;
Exothermic material (iron powder, lime carbonate and calcium oxide): account for 1%-30%;
Other auxiliary material (neutralizing agent: slipproofing agent, sanitas): an amount of.
Embodiment 3:MEG-ethanol powder itself is exactly the solid Snow Agent, and the aqueous solution of 20-30% is exactly the liquid Snow Agent.
Embodiment 4: modified ammonium bicarbonate itself is exactly the solid Snow Agent, and the aqueous solution of 20%-30% is exactly the liquid Snow Agent.
Embodiment 5: the micro encapsulation percarbamide itself is exactly the solid Snow Agent, and the aqueous solution of 20%-30% is exactly the liquid Snow Agent.
Embodiment 6: the MEG-ethanol powder with 25%, 25% modified ammonium bicarbonate, 35% wilkinite, 4% iron powder, 1% high-strength absorbing agent, 5% lime carbonate or the percarbamide thorough mixing of calcium oxide and 5% just make the compound solid high-efficient environmental protective snowmelting agent.
