Description
Technical field
The invention belongs to deicing fluid technical field, particularly a kind of anti-freeze cooling liquid for motor vehicle and preparation method thereof.
Background technology
Anti-freeze cooling liquid, be called again deicing fluid, it is the cooling fluid with antifreeze function, except the cooling system for motor car engines such as automobiles, another effect of anti-freeze cooling liquid is, unfrozen cooling fluid while preventing that cold season from stopping and spalling scatterer and freezing engine cylinder block, thus affect the use of motor vehicle, for motor vehicle was used in low period of temperature or area, anti-freeze cooling liquid must have good resistance to frost.
Cooling performance and resistance to frost have formed two large salient featuress of anti-freeze cooling liquid, and at present as the cooling performance of basic property, more and more can not get people's concern.At cooling system for motor vehicle, water cooled system particularly, people trend towards using simple cooling fluid, or are only in water, to add a small amount of frostproofer, with this, prevent the harm that cooling fluid ice up in winter causes motor vehicle.This way has obviously been ignored cooling fluid impact on cooling performance on the incrustation scale of the corrosion of cooling system and generation, life-time service, not only can not effectively reach cooling effect, can cause on the contrary the cooling system that the accumulation of part of cooling system corrosion or incrustation scale causes to lose efficacy, anti-freeze cooling liquid affects the normal operation of motor car engine, therefore also must possess antiseptic property and anti-scaling property.
Existing anti-freeze cooling liquid kind is more, there are alcohols deicing fluid, inorganic salt deicing fluid and polyose deicing fluid etc. multiple, wherein with alcohols deicing fluid, use the most extensive, because it has the corrodibility of part of cooling system little, freezing point is low, the plurality of advantages such as stability is better, and in numerous alcohols deicing fluid, the water base deicing fluid share of market of ethylene glycol is the highest.
The water base deicing fluid of existing ethylene glycol, take ethylene glycol as mother liquor, then adds suitable quantity of water and rust-preventive agent or inhibiter, forms anti-freeze cooling liquid, or adds a small amount of metal passivator, defoamer, so that cooling fluid reaches good antiseptic property.
Application number is that 201010515736.4 Chinese patent application " full organic engine cooling liquid " discloses a kind of anti-freeze cooling liquid that ethylene glycol is mother liquor of take, and its composition comprises ethylene glycol 1000 mass parts, dodecanedioic acid 16-20 mass parts, undecane diacid 5-9 mass parts, phenylpropyl alcohol triazole 1-5 mass parts, 2 ethyl hexanoic acid 3-6 mass parts, hydroxy-benzoic acid 0.5-3 mass parts, hydrolytic polymaleic anhydride 0.05-0.1 mass parts, defoamer 0.1-0.3 mass parts.Hence one can see that, and the technical scheme that this application is claimed, by adding a large amount of organic additives, has improved the anti-performance of hard water of cooling fluid, and had good Corrosion Protection, is the good cooling fluid of effect, but the composition first adding is more, and cost is larger; Secondly, cooling fluid unstable properties, is unfavorable for preserving and life-time service; The 3rd, the freezing point of cooling fluid and the temperature difference of boiling point are also little, and applicable region is limited, and quality is general.
Therefore good anti-freeze cooling liquid, not only needs to have good resistance to frost, and, cooling fluid anticorrosion, anti-scaling property is also most important, how to promote the over-all properties of anti-freeze cooling liquid, is the trend of following anti-freeze cooling liquid development.
Summary of the invention
The technical problem that the present invention solves: for the problems referred to above, the invention provides and a kind ofly not only there is good resistance to frost, and there is the anti-freeze cooling liquid of good anticorrosion and anti-scaling property, and the preparation method of this anti-freeze cooling liquid.
