Abstract
The present invention proposes a kind of oil engine cooling oil, be made up of following component: 8 ~ 15% deionized waters, 78 ~ 84% dibasic alcohol, 0.5 ~ 5% 8 carbon atom and above unary fatty acid and/or binary of fatty acids, 0.15 ~ 1.5% Sodium Benzoate and 0.5 ~ 3% caustic alkali.Cooling oil freezing point of the present invention can-55 ~-45 DEG C, boiling point can change between 115 ~ 124 DEG C, meet the demand of domestic automobile oil engine to boiling point, both improved internal-combustion engine cooling system outlet temperature, its life performance can not be affected again.
Description
Technical field
The present invention relates to the oil engine cooling oil that a kind of cooling system for motor vehicle uses.
Background technology
China's internal-combustion engine cooling system uses the deicing fluid of boiling point 100 ~ 108 DEG C as heat-eliminating medium always for many years, and easily producing steam when engine temperature is more than 100 DEG C affects heat-transfer effect.According to complex reaction mechanism, the interval heat conductivility that liquid seethes with excitement is nearly the strongest.It is reported, external water-free cooling uses boiling point to reach 191 DEG C, but usually makes engine cylinder cap, high oil temperature, while elimination engine boils, produces again other drawback.Chinese patent CN101481601A discloses a kind of car combustion engine cooling oil, this cooling oil freezing point can-38 ~-42 DEG C, boiling point can change between 125 ~ 140 DEG C.The cooling oil that this patent provides is only applicable to imported auto oil engine.But China's domestic automobile is due to the restriction of the condition such as steel, sealing technology, and oil engine works long hours the life-span of easily causing oil engine damage, shortening oil engine more than 125 DEG C, affects machine oil viscosity, affect its sealing and lubricant effect.
Summary of the invention
The present invention proposes a kind of internal combustion engine of motor vehicle cooling oil of applicable China's national situation, and technical problem to be solved is cooling oil moderate boiling point, has both improved internal-combustion engine cooling system outlet temperature, can not affect its life performance again.
Technical scheme of the present invention is achieved in that
A kind of oil engine cooling oil, its raw material composition counts by weight percentage and comprises:
Described dibasic alcohol is selected from one or both mixing dibasic alcohol in ethylene glycol, propylene glycol or butyleneglycol.
Described organic acid is selected from eight carbon atoms and above unary fatty acid and/or binary of fatty acids as suberic acid, sad, nonane diacid, n-nonanoic acid, sebacic acid, capric acid etc., and is the mixture of unary fatty acid and binary of fatty acids, preferably octanoic acid and sebacic acid.
Described caustic alkali is sodium hydroxide or potassium hydroxide, preferred sodium hydroxide.
The pH of described oil engine cooling oil is 7.5 ~ 8.5.
Making method of the present invention:
The dibasic alcohol measured in proportion is joined in reactor, stirs, then the organic acid measured in proportion, stir, be heated to 80 ~ 100 DEG C, be incubated 30 minutes to 1 hour, obtain transparent liquid.Be dissolved in deionized water by caustic alkali and Sodium Benzoate, slowly join in reactor, adjust ph is 7.5 ~ 8.5, cools and obtain outward appearance clarification, transparent cooling oil after stirring.
The freezing point of this cooling oil can-55 ~-45 DEG C, boiling point changes between 115 ~ 124 DEG C, when deionized water consumption is on the high side, freezing point is higher, boiling point is lower, and instead then freezing point is lower, boiling point is higher.This makes cooling oil of the present invention can adapt to the needs of different oil engine.
Caustic alkali of the present invention and organic acid reaction, generate aliphatic salt, prevent all kinds of metallic corrosion, not easily produce high pressure, thus reach and prevent air chamber from producing.
Oil engine is when starting, and thermostat is not opened, and electronic fan does not also turn, and object reaches rapidly working temperature to shorten start time.Cooling oil of the present invention has temperature variant running viscosity, slow in the heat radiation of engine temperature less than 100 DEG C, and more than 100 DEG C more close to boiling section between heat-transfer effect better, this low-temperature heat accumulating and high temperature fall apart the working condition of the very proper oil engine of thermal property.
