Abstract
The invention discloses a kind of high-thermal-conductivity anhydrous engine cooling oil, which comprises the following raw materials in percentage by mass: 85-95% of propylene glycol, 0.5-10% of ethylene glycol, 0.1-3% of an acid, 0.1-2% of vanadium oxide, and 3-5% of nano aluminum nitride. In the invention, the propylene glycol and the ethylene glycol are combined for used, so that the high boiling point and low freezing point of thermal-conducting oil are both ensured, and an appropriate viscosity is obtained; in addition, the addition of the nano aluminum nitride greatly improves the thermal conduction effect of the thermal-conducting oil. According to the invention, based on a consideration that an engine is used for a long time, the coefficient of thermal conductivity is high, and no corrosion is caused to an engine system, the defects that the thermal conductivity of cooling oil in the prior art is low, and the like are overcome.
Description
Technical field
The present invention relates to a kind of organic and inorganic chemical composition for engine cool, is a kind of motor car engine cooling oil furtherly.
Background technology
For a long time, China's engine-cooling system is generally all used the deicing fluid of boiling point lower (100 ~ 110 ℃) as cooling fluid, there is many problems in this cooling fluid, such as, when engine temperature surpasses 100 ℃, cooling fluid vaporization aggravation, very easily produces a large amount of bubbles, have a strong impact on the effect of Cooling Heat Transfer, temperature further raise (or highlands) even produce the problem such as boil; In addition, moisture height in lower boiling cooling fluid, easily produces the problems such as corrosion and dirt.
In recent years, domestic scientific worker has developed the substitute products of many moneys automobile cooling.CN 101481601 A disclose a kind of engine cool oil, mainly comprise deionized water, ethylene glycol, monobasic/binary of fatty acids and caustic alkali, and boiling point can reach 125 ~ 140 degree.CN 101481601 discloses a kind of by water, propylene glycol, and the cooling fluid that organic acid and potassium hydroxide form, freezing point is at-38 ~-42 ℃, and boiling point is in 125 ~ 140 ℃.But such cooling fluid thermal conductivity is lower, weakened the exchange capability of heat of cooling fluid.These moisture cooling oil systems exist certain vaporization losses characteristic and the corrosive problem to cooling system equipment, need frequent replacing in vehicle use procedure.Anhydrous condition, during the useful life of vehicle, can not change in theory, thereby traditional various inhibiter that contain have been avoided, Scale inhibitors, sterilant, the trouble of the aq. type engine coolant periodic replacement of the Harmful chemicalss such as defoamer, and the problems such as environmental pollution brought of discarded cooling fluid.High boiling point attribute can make cooling system equipment work under suitable high-temperature low-pressure environment, and fuel oil working temperature is high, and sufficient combustion has improved the temperature difference of high temperature coolant and environment and forced heat exchange and heat-sinking capability.CN 102585782 A disclose a kind of nano waterless cooling oil, mainly by propylene glycol, nano-oxide, cesium formate, Trimethyl glycine, citric acid and ammonium citrate, formed, this cooling fluid is compared traditional cooling fluid thermal conductivity and is increased, but effect is still undesirable.
Summary of the invention
Based on engine use for a long time, high thermal conductivity coefficient with to the free from corrosion consideration of engine system, the invention discloses a kind of waterless cooling oil, make up prior art heat-conducting effect low wait not enough.
The object of the invention is to overcome the deficiencies in the prior art, a kind of nano aluminum nitride cooling oil for engine high-temperature cooling technology is provided.
The anhydrous engine cool oil of high heat-conducting type of the present invention, wherein the quality group of each raw material becomes:
Propylene glycol 85 ~ 95%
Ethylene glycol 0.5 ~ 10%

Weigh successively propylene glycol, ethylene glycol, organic acid and organic vanadium, be fully stirred to completely and dissolve, then add nano aluminum nitride, under the condition of clarifixator homogeneous, be dispersed to transparent oily liquid.
Described propylene glycol and ethylene glycol are main body composition, and the interpolation of a small amount of ethylene glycol can effectively reduce oil viscosity, improve thermal conductivity;
Described organic acid is monobasic or diprotic acid, specifically includes but not limited to lauric acid, citric acid, Trimethyl glycine, and described mineral acid can be hydrochloric acid, sulfuric acid, phosphoric acid etc.;
Described vanadium oxide specifically includes but not limited to vanadous oxide, methyl ethyl diketone vanadyl (IV), mainly plays and dissolves heat-exchange system oxide on surface, the effect that improves heat exchanger effectiveness;
Described nano aluminum nitride particle diameter is lower than 40 nanometers.
The present invention is with respect to the advantage of prior art cooling oil: propylene glycol and ethylene glycol are used in combination, and makes thermal oil both guarantee high boiling point and low-freezing, obtains again suitable viscosity; In addition, adding of nano aluminum nitride, has improved the heat-conducting effect of thermal oil greatly.
