Abstract
The invention relates to a motor vehicle antifreeze fluid additive with high corrosion inhibition performance and a preparation method thereof and belongs to the technical field of antifreeze fluid. The motor vehicle antifreeze fluid additive is prepared from, by weight, 5-10 parts of ammonium nitrate, 3-5 parts of sodium pyrophosphate, 2-4 parts of sodium phosphate, 1-2 parts of sodium molybdate benzene, 1-3 parts of benzotriazole, 0.5-1 part of itaconic acid homopolymer, 0.1-0.3 part of methyl benzotriazole, 0.1-0.3 part of polyoxyethylene alkylphenol ether, 0.2-0.4 part of thiourea or thiourea derivative, 0.1-0.3 part of mildew preventive, 0.2-0.4 part of hydrocarbon imidazoline quaternary ammonium salt and 0.5-1 part of nonionic surfactant. Amine, borax and silicate are not added to the antifreeze fluid additive, environment is not influenced, the problem of scaling is avoided, the freezing point is low, and good corrosion resistant performance is achieved.
Description
Technical field
The present invention relates to automobile antifreezing solution additive of a kind of high rust inhibition and preparation method thereof, belong to deicing fluid technical field.
Background technology
Automobile antifreeze solution is the circulatory mediator of car engine cooling system, and the most frequently used is water.Water have many advantages, as: originate wide, nontoxic, inexpensive, have good heat conductivility etc.For a long time, water uses as the cooling fluid of motor car engine always.But water has many shortcomings, as freezing point is high, when temperature is lower than 0 DEG C, water freezing makes volume increase. easily cause water tank or Cooling system pipe spalling; The boiling point of water is low, during summer high temperature, when travelling under engine is in severe condition, water temperature can be caused to raise, even seethe with excitement, affect automobile normal running; Form incrustation scale after the metallic salt be dissolved in water is heated, reduce heat transfer efficiency; Water also can make metal rusting.Therefore, people are finding a kind of novel refrigerant to replace water always.First adopt the aqueous solution of salt (as calcium chloride, magnesium chloride, SODIUMNITRATE, Sodium Nitrite) freezing point can be reduced to less than-30 DEG C, but corrosion problem can not be solved.Also can freezing point be reduced with sugar and honey, and not corroding metal, but expensive, poor heat stability.Though it is low to make refrigerant condensation point with kerosene and diesel oil, poor heat transfer, easily burning, there is swelling action to rubber, also do not adopt.Before and after World War II, once used methyl alcohol, ethanol as refrigerant, although it is inexpensive, freezing point is low, boiling point was low, volatile, easy firing can not become desirable refrigerant.
Need the material adding other in deicing fluid, play inhibition, the effect such as anticorrosion.Application formulation types is the earliest silicate, silicate is a kind of inhibiter with multiple efficacies in anti-freeze cooling liquid, silicate corrosion inhibitor can suppress the generation corrosion phenomenon on aluminum metal surface preferably, good provide protection is all had to many metals such as iron and steel, not only there is shock absorption effective, and price is extremely cheap, the very applicable every field being widely used in corrosion prevention for a long time, this formula once obtained broad development. but this formula makes the stability of silicate worse and worse over time along with the difference of additive, part gelatinous precipitate can be separated out, very easily reduce its corrosion inhibition, and cause this formula in use to make its heat conductive efficiency reduce and cause the Yin Wendu of engine own too high and damage.Also have in some frostproofers and use borate, it has good anticorrosion ability to steel, iron under any condition, and little on portion of material impacts such as the copper in scatterer, tin.And effectively can slow down oxygenizement, more importantly low price, so be used to main anti-corrosive ingredi more.In the past, in the U.S., Japan just to bring into use borate deicing fluid, the sixties Japanese market is sold based on the more type deicing fluid of borate addition. in this period, often there is scatterer blocking in automobile aluminum metallization engine-cooling system according to investigations, the fault caused because temperature is too high. show through investigation, borate can corrode aluminum metallization parts, and scatterer blocks by its corrosion product.
It is a kind of Anti-freeze fluid fluid composition that CN103102872B discloses, and it is by ethylene glycol, glycerine, SODIUMNITRATE, water glass, isocaprylic acid, SA, DC11, citric acid, Sodium Benzoate, tripoly phosphate sodium STPP, benzotriazole, Vencide, p-NP, polysiloxane, defoamer, fluorescent orange, deionized water forms.But part gelatinous precipitate can be separated out containing silicate in above-mentioned deicing fluid, very easily reduce its corrosion inhibition, and cause this formula in use to make its heat conductive efficiency reduce and cause the Yin Wendu of engine own too high and damage.
Summary of the invention
The object of the invention is: provide a kind of deicing fluid additive, this additive goes for glycol/water deicing fluid, effectively can produce protection against corrosion, press down the effect of bubble, and make deicing fluid have lower freezing point.
Technical scheme is:
