Abstract
The present invention relates to an antifreezer for freeze protection of water-bearing particulates. Because of the low freezing point, the antifreezer can change the structure of ice crystal to make water-bearing coal or mineral powder form acicular or formless structure under the condition of-40 DEG C of air temperature. The binding force among the molecules is weak in the acicular or formless structure, so that the freezing strength is weakened. The present invention is prepared from 10 to 40% of diethylene glycol, 10 to 25% of glycol, 15 to 35% of amine carbonate and 0.01 to 0.6% of surfactant.
Description
The present invention relates to a kind of material and compound method thereof of frostproofer.
It is antifreeze that the present invention is suitable for the aqueous particulate thing, is particularly suitable for moisture coal and aqueous fine ore is antifreeze.
At present, in the world during cold district transportation aqueous particulate thing, usually make between the particulate matter, freeze between particulate matter and the car body, brings very big difficulty to unloading because temperature crosses low.Usually, prevent that the way that particulate matter is freezed from being to use frostproofer.United States Patent (USP) for example: a kind of control of ice and snow agent (patent No.: 3928221), i.e. frostproofer mainly is 23～25% urea by weight percent, the ethylene glycol of 11-15%, and 35～40% methyl alcohol is formed.For preventing that carrier vehicle from being corroded, in frostproofer, added weight percent and be 0.2～2% the sodium oleate and the mixture of sulfonic acid Oleic acid sodium salt.The characteristics of this frostproofer are: under-40 ℃ temperature condition, ice and snow is thawed.If spray the aqueous particulate thing with this frostproofer in advance, can under-40 ℃ of temperature conditions, not freeze.But because of containing the methyl alcohol inflammable substance in this frostproofer, make this frostproofer flash-point lower, become the unsafe factor in the transportation.
The purpose of this invention is to provide a kind of good freezing protection effect, cost is low, freezing point is low (not freezing under 40 ℃ of temperature conditions), nonflammable and safe and reliable frostproofer.
Moisture coal or fine ore can be unloaded smoothly, its freezing strength is weakened.Chemical deicers can change the structure of ice crystal because of very low freezing point is arranged, and makes moisture coal or fine ore under-40 ℃ of temperature conditions, becomes acicular or unformed structure.In this structure, the bonding force between the molecule is little, so its freezing strength weakens.
Component of the present invention should be selected water miscible monohydroxy, polyol for use.What preferentially select should be the polyhydroxyalkanes of low carbon atom.For example methyl alcohol, ethanol, ethylene glycol, Diethylene Glycol, propylene glycol etc.Other compound such as triglycol, glycerine and sugar etc. can use.Be best wherein with ethylene glycol.Also having a kind of is water miscible nonvolatile organism.Require to lose by evaporation without any composition in use, this compound has a hydrophilic group at least.For example amine, carboxyl both can be polymkeric substance, also can be non-polymers.As acetic acid, sodium-acetate, Ammoniom-Acetate, carboxamide etc.Polymkeric substance can be used kollidon, polyacrylamide etc.
In addition, in frostproofer, can also add have on a small quantity infiltrative, mainly contain the compound of nonionic or anionic surface activity thing.
Mainly consider ample supply and prompt delivery aspect material choice, low price, nontoxic or toxicity is very little, corrodibility is little to human body, environmental nonpollution, has the long period to prevent ice and snow accumulative ability, validity period is long, blending process is easy etc.
The present invention mainly adopts following raw material, and prepares by following weight percent, temperature of reaction, reaction times:
1. the contained weight percent of various compositions in the frostproofer:
Diethylene Glycol: 10～40%
Ethylene glycol: 10～25%
Carboxamide: 15～35%
Water: 30～60%
Tensio-active agent 105:0.1～0.6%
2. the compound method of frostproofer:
At first in container, put into 10～40% Diethylene Glycol, and stir.Add 10～30% ethylene glycol, 30～60% water, 15～35% carboxamide, 0.1～0.6% tensio-active agent while stirring, use NH at last
4OH regulates pH value, makes pH value reach 8-9.Whole process for preparation carries out at normal temperatures and pressures.
Embodiment:
In container, put into 26% Diethylene Glycol and stir.Add 15% ethylene glycol, 33.4% water, 25% carboxamide, 0.6% 105 tensio-active agents while stirring.Use NH at last
4OH regulates pH value, makes pH value reach 8-9.Whole process for preparation carries out at normal temperatures and pressures.
Tensio-active agent 105: contain chemical ingredientss such as Fatty Alcohol(C12-C14 and C12-C18), Soxylat A 25-7, alkylol amide.
Annotate: tensio-active agent 105 manufacturers are detergent factory, Beijing.
