Problems solved by technology

It is disclosed that there are ammonium bicarbonate, red phosphorus, potassium chloride, calcium nitrate, magnesium nitrate, ethylene glycol and other ingredients, reducing the content of chloride salts, changing from chloride salts to other inorganic salts, although the corrosion has been solved to a certain extent However, the damage to soil, water sources, plants and aquatic animals has not been solved. On the contrary, it will cause the increase of nitrogen content and eutrophication of water body. It is not a real environmental protection deicing agent.
All kinds of environmentally friendly deicing agents that appeared successively later could not get rid of inorganic salts, and failed to fundamentally solve the problems of environmental protection and environmental friendliness.

Embodiment 1

[0035] (1) Take 40Kg of ethanol and add it to the preparation kettle, start stirring, put 125kg of pure water into the kettle to make it fully uniform, and then inject the prepared ethanol solution into the reaction kettle with a metering pump. Replace with high-purity nitrogen to reduce the oxygen content to below 0.1%, pressurize with nitrogen to the pressure of the reactor to 1.0MPa. Turn on the heat-conducting oil furnace, heat up the reaction kettle to 180° C., and stir for 2 hours.

[0036] (2) Add 125kg of pure water, 5Kg of sucrose, 1.25kg of isosorbide, 2.5Kg of ethylene glycol, 25g of glycerol, 1.25kg of acesulfame potassium, 37.5kg of sodium tripolyphosphate, 6.25kg of aspartame, and Add 7.5kg of sodium phosphate, 125kg of methanol, and 8.75kg of threitol into the preparation kettle, start stirring to fully dissolve them, turn on the metering pump, inject the prepared solution into the reaction kettle, heat, and stir for another 2 hours.

Embodiment 2

[0040] (1) Take 10Kg of ethanol and add it to the preparation kettle, start stirring, add 30Kg of pure water into the preparation kettle to make it fully uniform, and then inject the prepared ethanol solution into the reaction kettle with a metering pump. Replace with high-purity nitrogen to reduce the oxygen content to below 0.1%, pressurize with nitrogen to the pressure of the reactor to 1.1MPa. The heat conduction oil furnace was turned on, the temperature of the reaction kettle was raised to 178° C., and the mixture was stirred for 12 hours.

[0041] (2) 30Kg of pure water, 3.0kg of sucrose, 1g of isosorbide, 1Kg of ethylene glycol, 5Kg of glycerin, 1kg of acesulfame potassium, 5kg of sodium tripolyphosphate, 1kg of spartame, 5kg of sodium hexametaphosphate, Add 1Kg of methanol and 5Kg of threitol into the preparation kettle, start stirring to fully dissolve them, turn on the metering pump, inject the prepared solution into the reaction kettle, heat, and stir for 48 hours....

Embodiment 3

[0045] Take 50Kg of ethanol and add it to the preparation kettle, start stirring, add 200Kg of pure water into the preparation kettle to make it fully uniform, and then inject the prepared ethanol solution into the reaction kettle with a metering pump. Replace with high-purity nitrogen to reduce the oxygen content to less than 0.1%, and pressurize with nitrogen until the pressure of the reactor is 0.8MPa. Turn on the heat-conducting oil furnace, heat up the reaction kettle to 185° C., and stir for 20 hours.

[0046] 200Kg of pure water, 5Kg of sucrose, 10kg of isosorbide, 100kg of ethylene glycol, 500Kg of glycerin, 10Kg of acesulfame potassium, 50Kg of sodium tripolyphosphate, 10Kg of aspartame, 10Kg of sodium hexametaphosphate, 300Kg of methanol, Add 10Kg of threitol into the preparation kettle, start stirring to fully dissolve it, turn on the metering pump to inject the prepared solution into the reaction kettle, heat, and stir for another 6 hours.

Abstract

The invention relates to a snow-melting agent, in particular to an environment-friendly snow-melting agent and a preparation method thereof. The environment-friendly snow-melting agent comprises, by weight, 10-60 parts of water, 1-5 parts of ethyl alcohol, 0.3-0.5 part of saccharose, 0.1-1.0 part of isosorbide, 0.1-10 parts of ethanediol, 0.5-50 parts of glycerine, 0.1-1 part of acesulfame, 0.5-5 parts of sodium tripolyphosphate, 0.1-1 part of aspartame, 0.5-1 part of sodium hexametaphosphate, 0.1-30 parts of methyl alcohol and 0.5-1 part of threitol. The snow-melting agent prepared through the method is very high in snow melting efficiency, convenient to transport, safe to use and store, convenient to spray, low in use labor intensity, small in labor cost, small in dosage, high in snow melting speed and free of residues, does not pollute water resources, does not corrode buildings or pavements, does not do harm to plants or aquatic animals, does not destroy the pH value of soil and does not cause salinization of the soil.

Description

technical field [0001] The invention relates to a deicing agent, in particular to an environment-friendly deicing agent and a preparation method thereof. Background technique [0002] Traditional deicing agents are chlorine-salt deicing agents, which consist of or contain inorganic chlorine salts such as sodium chloride, magnesium chloride, and calcium chloride, among which calcium chloride is the main active ingredient. Such deicing agents will inevitably cause certain damage to buildings and roads, water sources, soil, plants and aquatic animals. In view of this, the chloride-salt deicing agent was improved later, and it was improved to other nitrates and mixed with a certain amount of ethylene glycol. For example, the patent application number is 99109322.4, and the patent name is: environmental-friendly snow-melting agent for ice and snow fast solvent and its preparation method. It is disclosed that there are ammonium bicarbonate, red phosphorus, potassium chloride, ca...
