Abstract

The invention relates to an anticorrosive antifreezing solution composition which comprises ethylene glycol, glycerol, sodium nitrate, sodium silicate, isooctanoic acid, sebacic acid, undecanedioic acid, citric acid, sodium benzoate, sodium tripolyphosphate, benzotriazole, sodium 2-mercaptobenzothiazole, p-nitrophenol, polysiloxane, defoaming agent, methylene blue and deionized water. According to the invention, the anticorrosive antifreezing solution can be prepared from existing chemical materials on the domestic market through the method provided by the invention, can effectively solve the problem of corrosion to copper, steel, iron, aluminum and tin and the problem on precipitation in the storage process, and simultaneously has the advantages of high stability quality, low volatilization possibility, low pipeline blocking possibility and high freezing protection, rust prevention and scaling resistance.

Description

A kind of engine fluid
Technical field
The present invention relates to a kind of modulation formula of engine fluid.
Technical background
According to investigations, the motor car engine source of trouble of the whole world more than 50% is in cooling system.Along with the improvement of engine structure and the progress of material technology, Modern Automobile Engine is compared with old-fashioned engine, the operating temperature that outstanding feature is exactly Modern Engine is high, normal working temperature higher limit generally all surpasses 100 ℃, and this has just proposed Secretary to the deicing fluid of engine.But most of deicing fluid of selling in the market is the product take ethylene glycol as main raw material, the ethylene glycol boiling point is high, volatility is little, modest viscosity and vary with temperature little, Heat stability is good, be a kind of desirable frostproofer mother liquor, adding appropriate phosphoric acid salt or silicate to reach antiseptic and rustproof effect, be combined into together deicing fluid.But although because the use of phosphoric acid salt and silicate can reach antiseptic and rustproof effect, cause simultaneously the generation of the phenomenon such as fouling, silicate material is gum deposit very easily, stops up cooling system, has reduced the transfer efficiency of circulating liquid; In addition, because phosphoric acid salt easily forms incrustation scale in hard water.And the incrustation scale that forms is attached to the metallic surface of scatterer inside, if can not regularly clear up it, thick incrustation scale will seriously affect the function of heat-removal system, cause boiling, lack of water, and even sticking cylinder, tile kilning.
Summary of the invention
The invention provides a kind of modulation formula of engine fluid.
Deicing fluid forms with following ingredients: ethylene glycol, glycerine, SODIUMNITRATE, water glass, isocaprylic acid, SA, DC11, citric acid, Sodium Benzoate, tripoly phosphate sodium STPP, benzotriazole, Vencide, p-NP, polysiloxane, defoamer, methylenum coeruleum, deionized water.Concrete weight proportion is as follows:
Ethylene glycol 35~50%
Glycerine 2~15%
SODIUMNITRATE 0.3~0.05%
Water glass 3.0~1.0%
Isocaprylic acid 2.0~2.5%
SA 0.4~0.45%
DC11 0.6~0.5%
Citric acid 1.8~2.4%
Sodium Benzoate 2.5~0.8%
Tripoly phosphate sodium STPP 0.2~0.01%
Benzotriazole 0.45~0.05%
Vencide 0.8~0.05%
P-NP 0.2~0.01%
Polysiloxane 0.2~0.05%
Defoamer 0.03~0.005%
Methylenum coeruleum 0.006~0.001%
The deionized water surplus.
The present invention contains stable silicate, and provides remarkable anticorrosive protection to cooling system, and it is different from the conventional deicing fluid of the ethylene glycol fundamental mode of selling on the existing market.Its advantage is: anti-condensation, overheated, get rusty and corrode, the protection refrigeration system all metallic surfaces, comprise aluminum hardware.Can not damage the rubber components such as radiator hose, packing ring, simultaneously, can also prevent too much foam, prevent due to the caused calcium magnesium precipitate of water hardness, thereby avoid forming focus in end and block part.This deicing fluid can reach-65 ℃ of left and right and keep liquid after testing, and boiling point is more than 100 ℃.
Concrete formula is as follows:
Embodiment 1
Ethylene glycol 45%
Glycerine 10%
SODIUMNITRATE 0.2%
Water glass 1.5%
Isocaprylic acid 2.2%
SA 0.43%
DC11 0.55%
Citric acid 2.0%
Sodium Benzoate 1.5%
Tripoly phosphate sodium STPP 0.1%
Benzotriazole 0.3%
Vencide 0.5%
P-NP 0.1%
Polysiloxane 0.1%
Defoamer 0.02%
Methylenum coeruleum 0.005%
The deionized water surplus.
Record the type deicing fluid through the glassware corrosion test and can satisfy the driving driving demand of 2~3 years, design parameter is as follows:
Figure 107765DEST_PATH_IMAGE001
After the present invention's process repetition test, screening, adopt scientific and reasonable raw material and proportioning, and through the operating procedure of standard, the deicing fluid of making has good antifreezing effect, and the contained material of deicing fluid of the present invention is nontoxic, non-corrosiveness, and adjusts pH value in process for preparation, form suitable alkalescence, therefore, life-time service can not produce burn into corrosion and fouling to water tank, satisfies service requirements fully.
