Description
Technical field
The present invention relates to a kind of water-free cooling, relates more specifically to a kind of water-free cooling for automobile engine,
Belong to coolant preparation field.
Background technology
Traditional general freezing point of coolant only has -25~-45 DEG C, and boiling point typically can only achieve 120 DEG C, therefore, run into low temperature
Or during overheat, engine start may be caused difficult, or engine overheat produces vapour lock.Traditional coolant due to containing
Water, the problems such as easily producing incrustation scale, burn into vapour lock, poor lubricity and service life short waste of resource, have a strong impact on cooling system
Operating efficiency and service life.The automobile waterless coolant of long-life and energy-conserving and environment-protective is as coolant development and application
Direction, still, water-free cooling is mainly the composition that a variety of corrosion inhibitors of liquid addition obtain based on propane diols at present,
Because propane diols viscosity is larger, freezing point is higher, it is impossible to meet the requirement of engine, also have some report propane diols polynary with other
Alcohol is mixed into the invention of basal liquid, such as：
A kind of life-cycle water-free cooling solution of CN102367379A patent applications report, including propane diols 10-50%, second
Glycol 50-80%, triazole class compounds 0.1-1%, decanedioic acid 0.5-3%, adipic acid 0.2-1%, sodium benzoate 0.5-
1.5%th, inorganic base 0.3-5%, defoamer 0.01-0.1%, coloring agent 0.01-0.1%, solves ethylene glycol-water type coolant
The shortcomings that.
CN102061147A patent application discloses a kind of non-aqueous heat transfer fluid, including ethylene glycol 60-70%, propane diols
30-40%, at least one preservative.Realize the anhydrous and substantially nontoxic effect of coolant.
A kind of non-aqueous coolant for engine of CN102250591A patent applications report, it is with no less than 55% weight ratio
The propane diols of component is that main base-material forms to obtain water-free cooling.
A kind of non-aqueous coolant for engine of CN103059819A patent applications report, the coolant include basal liquid and
Compound corrosion inhibitor, wherein basal liquid include propane diols, ethylene glycol and diethylene glycol (DEG), can also add triethylene glycol and propane diols
Ether, wherein propylene glycol are propane diols or its condensation product and the ethers product generated after alcohols generation condensation reaction.
Although existing various engines water-free cooling in the prior art, cryogenic property is still suffered from i.e. in freezing point index
The requirement (can reach -55 DEG C northern China winter outdoor road temperature is minimum) of China's natural environment can not be met,
The boiling point of the common coolant in China highlands may only have 70~100 DEG C, and phenomenon of boiling often occurs in engine-cooling system,
Great potential safety hazard often also is brought because the high vehicle water tank of temperature boils in south China summer, is only improved cooling
Liquid boiling point could solve this problem.For defect present in prior art, the present inventor concentrates on studies the lists of various components
One performance and compound property, it is intended to develop a kind of anhydrous cooling of the comprehensive automobile engine of performance, it passes through the suitable of component
Screening and ratio optimization, promote respective storeroom to play larger cooperative effect, make coolant that there is good cryogenic property, ice
Point reaches less than -60 DEG C requirements for meeting China's all regions；There is high boiling point simultaneously, reach more than 185 DEG C, both
Solving plateau boiling point reduces the requirement that problem also meets southern summer.The present invention has uniqueness in coolant anti-corrosive properties
Advantage, substantially reduce coolant and the corrosiveness of engine is particularly to metallic aluminium (Technical Reform of Engine Castings main material) with good
Good defencive function；Other anti-oxidative stability of the present invention also has significant progress, it is therefore prevented that the oxidation of coolant own material
And acidifying, not only reduce corrosion but also substantially prolongs the service life of coolant, realization and engine same life-span, vehicle need not
Coolant is changed, i.e. energy-conservation environmental protection again.
