Description
Technical field
Invention belongs to the deicing fluid technical field, is specifically related to a kind of deicing fluid system of motorcycle cooling system being carried out omnibearing protection, relates in particular to a kind of locomotive anti-freezing fluid.
Background technology
Deicing fluid claims again non-freezing solution, and full name is anti-freeze cooling liquid, is as the automotive engine cooling system heat exchange medium, it is a kind of liquid of low freezing point, and the aqueous solution that contains at low temperatures certain glycol concentration can not freeze, and boiling point improves relatively, through after the technical finesse, its flowability, heat exchange performance be more in superior, has a winter antifreeze, prevent summer " boiling ", annual scale-deposit-preventing, the premium propertiess such as protection against corrosion, thereby operating mass and the work-ing life of improving locomotive engine.
Along with improving constantly of environmental consciousness and quality of life, people are to the demand cumulative year after year of Environmental Safety locomotive anti-freezing fluid.The kind of deicing fluid can be divided into eco-friendly organic acid type deicing fluid and general inorganic salt type deicing fluid according to the evaluation to environmental influence, and owing to easily biological degradation, pollution on the environment is little comparatively speaking for organic acid type deicing fluid.Nowadays at European ﹠ American Market, the deicing fluid such as phosphorous, boron ban use of, Volkswagen's engine fluid standard code can not contain the molybdic acid salt, and its smell etc. is had regulation, can not use the organic compound such as pungency, stink as additive.Therefore, relevant criterion requires more and more stricter to the deicing fluid that locomotive engine uses.
Summary of the invention
The purpose of this invention is to provide a kind of locomotive anti-freezing fluid, have low temperature resistantly, anti-boil, protection against corrosion, good antiscale property, high, the antibiotic algae of heat transfer efficiency, volatility are low, free from extraneous odour, to high-performances such as environmental protection close friends.
Realize that purpose technical scheme of the present invention is: a kind of locomotive engine deicing fluid mainly by mass percentage, comprises following component:
Ethylene glycol 28.4-57%

Defoamer 0.0002-0.0008%
Pigment dyestuff (green) 0.005%
The deionized water surplus
Locomotive anti-freezing fluid base type of the present invention is-No. 10 ,-No. 25 ,-No. 30 ,-No. 40 ,-No. 45 the trade mark of petrochemical industry standard, adapts to the wide geographic area use that minimum temperature is not less than-45 ℃.
The preparation method of locomotive anti-freezing fluid of the present invention: press 80% of ratio of component and add deionized water to reactor, and heat to 40-60 ℃ of addings other component materials except sodium hydroxide, EDTA, pigment dyestuff; After the stirring and dissolving, adding ethylene glycol proceeds to stir, dissolve sodium hydroxide with remaining 20% deionized water again, and add EDTA in this alkali lye, after the EDTA dissolving, add reactor and continue to stir 5-10min, and the green pigment dyestuff of limit stirring adding, at this moment solution is light green, and the pH value is 8-8.5; From reactor, solution is pumped into subsequently, pump into hyperfiltration machine (being not more than 100nm), make locomotive anti-freezing fluid.
The invention has the beneficial effects as follows, this antifreeze liquid phase is uniformly dispersed, good fluidity, and heat transfer efficiency is high, do not contain human body and harmful molybdenum salt, nitrite, borax and the amines additives of engine, protection against corrosion, scale-deposit-preventing belongs to organic type locomotive anti-freeze cooling liquid.
The present invention can be widely used in the cooling system of each machine locomotive engine, and particularly suitable is done the cooling fluid of low temp area locomotive engine.
