Abstract
The present invention provides a kind of multifunctional anti-freezing liquid suitable for various liquid cooling systems of internal combustion engine. The anti-freezing liquid consists of organic polyol, water, triethanolamine, organic phosphoric acid, substituted radical sulfonate, hydrolyzed maleic anhydride, EDTA or its sodium salt, water soluble fuel, etc. The present invention also relates to the preparation process of the anti-freezing liquid. The anti-freezing liquid has anti-freezing, anti-boiling, anticorrosive, anti-dust and antiscaling functions and stable storage performance.
Description
Invention field
The present invention relates to a kind of deicing fluid that is used for the liquid-cooled engine cooling system, be particularly useful for automobile and tractor.That this deicing fluid has is antifreeze, anticorrosion, rust cleaning, resistive connection dirt and be suitable for the stability of storage.This deicing fluid main body is with polyvalent alcohol water, and adds the homogeneous system that the number of chemical material is formed.
Background technology
Bleed off water coolant in machine owing to people forget for the moment winter, and the thing of many bodies and water tank bursting by freezing is happened occasionally.Thereby caused very big loss.Chinese patent CN1041382A discloses a kind of deicing fluid, and it is to be effective constituent with the alcohols.But as everybody knows, cooling system tends to transpiration cooling water constantly, if moisture evaporation too much, the machine temperature will raise, and is raised to a certain degree alcohols and will sends out and be inflammable, explosion hazard gases, will cause fire or blast in case meet fire, has potential safety hazard.In addition, the production cost of alcohols deicing fluid is also high.
Summary of the invention
Deicing fluid provided by the present invention is formed and is comprised:
(1) organic polyhydric alcohol is selected from ethylene glycol, vinylcarbinol, Diethylene Glycol, propylene glycol or its mixture, wherein preferred ethylene glycol;
(2) water comprises natural water, deionized water, distilled water, preferred distilled water;
(3) trolamine;
(4) organic phospho acid is selected from: 1-Hydroxy Ethylidene-1,1-Diphosphonic Acid (HEDP), amino many acyl groups methylenephosphonic acid (PAPEMP), 1.2.4-tricarboxylic acid, PBTC2-HPAA (HPA) 1-Hydroxy Ethylidene-1,1-Diphosphonic Acid (HEDP), wherein preferred HEDP;
(5) hydrolysis maleic anhydride;
(6) EDTA or its sodium salt;
(7) water-soluble dye, preferred methylene blue dye.
The proportioning of each component is in the deicing fluid:
Proportion of composing
Organic polyhydric alcohol 20-80
Water 20-75
Trolamine 0.5-2
Organic phospho acid 0.5-1
Hydrolysis maleic anhydride 0.1-0.5
EDTA or its sodium salt 0.1-0.05
Methylene blue dye 0.05-0.02
The preparation method of deicing fluid provided by the present invention is as follows:
(1) accurately takes by weighing organic polyhydric alcohol, trolamine, organic phospho acid, hydrolysis maleic anhydride, EDTA or its sodium salt, and methylene blue in proportion;
(2) water is added to the enamel still or the stainless steel still that can heat and have stirring, and stirs;
(3) with three ethanol, organic phospho acid EDTA or its sodium salt add in the entry successively, constantly stir, and make its dissolving, can heat in case of necessity;
(4) gently ethylene glycol is added in the above-mentioned mixed system, stirring fully is mixed;
(5) methylene blue dyestuff is joined in the mixed solution, fully be mixed, this moment, the PH of mixed solution was between the 8-9;
(6) with the filter stamen bucket filter of ∮=1UM, filtrate is deicing fluid;
(7) according to processing requirement to the examination and test of products, mainly be to detect freezing point, boiling point, pH value, and insolubles;
(8) open valve qualified deicing fluid is carried out can, the warehouse-in of labelling, dispatch from the factory.
The prepared deicing fluid of the present invention have good antifreezely, anti-boil, protection against corrosion, resistant to tarnishing, resistive connection dirt and can remove the dirty erosion of water tank, not volatile, long storage is stable.The preparation method of the utility model deicing fluid is simple, and chemical substance is all from domestic, and is common agents.Facility investment is low, does not lose a kind of methods of comparatively ideal preparation anti-icing fluid.This deicing fluid is applicable to import, the cooling system of homemade various motor car engines.
