Description
Technical field
The invention belongs to automobile protective articles for use and its preparing technical field, particularly to efficient corrosion-proof motor vehicle antifreeze fluid and its
Preparation method.
Background technology
Coolant also known as anti-icing fluid, by antifreeze additive and prevent metal from producing liquid that the additive of corrosion and water form
Body.It needs with freeze-proof, corrosion protection, heat conductivity and stay-in-grade performance.Motor vehicle antifreeze fluid is that efficient corrosion-proof contains spy
The coolant of different additive, is mainly used in liquid cooled engine cooling system, and it is antifreeze that anti-icing fluid has a winter, summer anti-boiling, entirely
Year scale-deposit-preventing, the premium properties such as anticorrosion.
The engine-cooling system of internal combustion vehicle is a liquid-cooled sealing and circulating body being made up of cylinder, chuck and water tank
System.The working condition of cooling system directly affects the normal operation of vehicle and the service life of vehicle.Anti-icing fluid is that internal combustion engine follows
The cooling medium of ring cooling system, is mainly made up of antifreezing agent, corrosion inhibiter, defoamer, coloring agent, antifungus agent, buffer agent etc..Respectively
Substantial amounts of research has all been done to this by state, constantly releases formula patent and excellent anti-icing fluid commodity.Some advanced countries antifreeze
Liquid popularity rate has reached 100 %.The popularity rate of domestic anti-icing fluid is relatively low, and it is import that commercially available anti-icing fluid has a great deal of, by
Higher in price, it is generally used for imported vehicle.Although domestic anti-icing fluid production increase in recent years is quickly, many products are due to lacking
Weary strict quality inspection and unified touchstone.For that purpose it is necessary to absorbing external advanced technology and combining the reality of China,
Development and Production multi-functional high efficient antifreeze liquid is meeting the growing market demand.Now domestic and international 95% second two used above
The aqua type anti-icing fluid of alcohol, ethylene glycol will not cause the obvious corrosion of material at normal temperatures, but temperature raises, and ethylene glycol can be by oxygen
Change, so that acidity is increased, generate multiple corrosive substances: the precipitation of these corrosive deposits and cause engine thermal conductivity decline,
Cause cooler pipe portion easily to block, cause engine overheat.
With the development of auto industry, the performance requirement also more and more higher to electromotor, the anti-icing fluid commonly used at present is antifreeze
Performance, thermal stability and corrosion-resistant stability all can not meet requirement it is therefore desirable to develop efficient corrosion-proof performance more
Plus excellent motor vehicle antifreeze fluid.
Content of the invention
The technical problem to be solved is for above-mentioned the deficiencies in the prior art, provides a kind of resistance to frost excellent
Different, thermal stability is good, has higher inhibition efficiency, efficient corrosion-proof motor vehicle antifreeze fluid of low cost and preparation method thereof.
For solving above-mentioned technical problem, the technical scheme that the present invention takes is: efficient corrosion-proof motor vehicle antifreeze fluid, by quality hundred
Divide ratio, be made up of following component: ethylene glycol 50-60%, glycerol 15-25%, BTA 0.1-0.15%, penta sodium pentachlorophenate
0.5-1.5%, sodium salicylate 0.5-1%, acrylic acid 1.5-2%, rare-earth salts 0.01-0.1%, defoamer 0.01-0.04%, dyestuff
0.005-0.01%, deionized water is surplus, and the preparation process of above-described motor vehicle antifreeze fluid is as follows:
(1) weigh each component according to mass percent；
(2) by deionized water, ethylene glycol, glycerol, rare-earth salts, defoamer and dyestuff mixed dissolution, it is warmed up to 25-35 DEG C, treats
After the clarification of this mixed solution, then add other components, be thoroughly mixed dissolving；
(3) mixed liquor obtaining step (2) is warming up to 50-60 DEG C, is incubated under conditions of vacuum is for 0.02-0.03mpa
45-60 minute, that is, obtain motor vehicle antifreeze fluid.
The invention has the beneficial effects as follows: ethylene glycol freezing point is low, and boiling point is high, viscosity little it is ensured that anti-icing fluid antifreeze and following
Ring cooling effect, glycerol good stability, low cost, can suitably reduce the consumption of ethylene glycol, further reduces cost, benzo three
Nitrogen azoles plays good corrosion mitigating effect to engine-cooling system metal erosion, and it is by the reaction on BTA molecule
The metal ion generating in group and corrosion process interacts and forms precipitation membrane or insoluble coordination compound film and play inhibition
Effect.Rare-earth salts, to there is synergism between BTA and other corrosion inhibiter, makes the protecting film of metal surface complete, from
And suppress corrosion of metal.Employ heating and the technique of vacuum heat-preserving in preparation method, substantially reduce each medium ingredients
The mixed dissolution time, improve efficiency, it is to avoid the generation of oxidation deterioration in process for preparation.
