Abstract
The present invention relates to a kind of automobile antifreezing solution additive of high rust inhibition and preparation method thereof, belong to anti-icing fluid technical field.Include following component by weight：0.2~0.4 part of 5~10 parts of ammonium nitrate, 3~5 parts of sodium pyrophosphate, 2~4 parts of sodium phosphate, 1~2 part of sodium molybdate benzene, 1~3 part of BTA, 0.5~1 part of itaconic acid homopolymers, 0.1~0.3 part of benzotriazole, 0.1~0.3 part of polyoxyethylene alkylphenol base ether, thiocarbamide or thiourea derivative, 0.1~0.3 part of mould inhibitor, 0.2~0.4 part of hydrocarbon imidazoline quaternary ammonium salt, 0.5~1 part of nonionic surfactant.Amine, borax, silicate are added without in the antifreeze solution additive provided in invention, on environment without influence, the problem of being not in fouling, and freezing point is low, Corrosion Protection is good.
Description
Technical field
The present invention relates to a kind of automobile antifreezing solution additive of high rust inhibition and preparation method thereof, belongs to anti-icing fluid technology neck
Domain.
Background technology
Motor vehicle antifreeze fluid is the circulatory mediator of car engine cooling system, most commonly water.Water have many advantages,
Such as：Source is wide, it is nontoxic, inexpensive, have good heat conductivility etc..For a long time, the water coolant as automobile engine always
Use.But water has many shortcomings, as freezing point is high, when temperature is less than 0 DEG C, water freezing make volume increase easily cause water tank or
Cooling system pipe spalling；The low boiling point of water, during summer high temperature, when engine is in harsh conditions downward driving, water can be caused
Temperature rise, or even boiling, influence automobile normal running；The metallic salt being dissolved in water forms incrustation scale after being heated, reduce heat transfer effect
Rate；Water can also make metal rusting.Therefore, people always search for a kind of new cooling agent to replace water.First using salt
The aqueous solution (such as calcium chloride, magnesium chloride, sodium nitrate, natrium nitrosum) can reduce freezing point to less than -30 DEG C, but can not solve corrosion and ask
Topic.Can also reduce freezing point with sugar and honey, and not corrode metal, but it is expensive, heat endurance is poor.Made with kerosene and diesel oil cold
Though but agent condensation point is low, poor heat transfer, easily burning, there is swelling action to rubber, also do not use.Before and after World War II, once
By the use of methanol, ethanol as cooling agent, although it is inexpensive, freezing point is low, low boiling point, volatile, easy firing can not turn into ideal
Cooling agent.
Need to add other materials in anti-icing fluid, play the effect such as inhibition, anti-corrosion.Using earliest formulation types
It is silicate, silicate is a kind of corrosion inhibiter with multiple efficacies in anti-freeze cooling liquid, and silicate corrosion inhibitor can be preferable
Ground suppresses the generation corrosion phenomenon of aluminium gold metal surface, has good protective effect to many metals such as steel, not only has slow
It is good to rush action effect, and price is extremely cheap, is very suitable for being widely used in for a long time the every field of corrosion protection, the formula
Once obtained broad development but the formula makes the stability of silicate as the difference of additive changes with time increasingly
Difference, can separate out part gelatinous precipitate, easily reduce its corrosion inhibition, and cause the formula to make its heat conductive efficiency in use
Reduce and cause engine to be damaged in itself because temperature is too high.Also have and borate is used in some antifreezing agents, it is in any condition
Under have good anticorrosion ability to steel, iron, and the portion of material such as the copper in radiator, tin are influenceed little.And can
Effectively slow down oxidation, more important is cheap, so being used for main anti-corrosive ingredi more.In the past, the U.S.,
Day, sale was antifreeze with the more type of borate addition on sixties Japanese market originally to begin to use borate anti-icing fluid
Liquid be main in this period, radiator blocking often occurs for automobile aluminum metallization engine-cooling system according to investigations, due to temperature
Failure caused by too high shows that borate can corrode aluminum metallization part by investigation, and its corrosion product will radiate
Device blocks.
It is a kind of anticorrosion antifreeze liquid composition that CN103102872B, which is disclosed, and it is by ethylene glycol, glycerine, sodium nitrate, silicic acid
Sodium, isooctyl acid, SA, DC11, citric acid, sodium benzoate, sodium tripolyphosphate, BTA, 2- sulfydryl benzene
And thiazole sodium, p-nitrophenol, polysiloxanes, defoamer, fluorescent orange, deionized water composition.But contain in above-mentioned anti-icing fluid
There is silicate to separate out part gelatinous precipitate, easily reduce its corrosion inhibition, and cause the formula to make its biography in use
Thermal efficiency reduces and causes engine to be damaged in itself because temperature is too high.
