Description
Technical field
The invention belongs to coolant liquid technical fields more particularly to a kind of coolant, automobile cooling and preparation method thereof.
Background technique
Automobile cooling is also known as anti-icing fluid, is mainly made of coolant, additive and water three parts.Coolant and water master
Play a part of to conduct heat, additive mainly has buffer, corrosion inhibiter, defoaming agent, preservative, dirt dispersion agent, emulsifier
With colorant etc..Combustion in IC engine gasoline in automobile engine generates power, and along with generating a large amount of heat, these
Heat needs timely to pass away, just can guarantee the normal work of engine.Extra heat passes through in cooling system in engine
Coolant liquid conducted, therefore it is required that coolant liquid not only good cooling results, summer anti-boiling, winter are antifreeze, and also have anti-corrosion
Erosion, anti-corrosion, prevents the functions such as bubble at scale-deposit-preventing, and cooling system can just be effectively protected, guarantee the safety traffic of automobile.
Most common automobile cooling has the disadvantage that currently on the market: (1) generally using ethylene glycol is coolant, a side
The freezing point of face ethylene glycol is minimum to be only sufficient to reach -50 DEG C, can not adapt to the high cryogenic region of severe cold, the biology poison of another aspect ethylene glycol
Property it is high, leakage and discarded ethylene glycol type coolant liquid cause to seriously endanger to natural environment；(2) the big portion of corrosion inhibiter used at present
Be divided into the compounds such as inorganic inhibitor, such as nitrite, phosphate, silicate, amine, on the one hand these substances to human body and
Environment is harmful, and still further aspect, these inorganic matters are unstable in coolant system, formation precipitating easy to reunite, anti-corrosion effects
Difference reduces the service life of coolant liquid to reduce the heating conduction of cooling system；(3) preservative used at present is most of
Containing phenyl ring or it is Form aldehyde release body for the substances such as benzoic acid and its salt, Kathon CG and paraben esters, dermatitis can be caused and increased to cause
Cancer risk, it is harmful to human body and environment, and the preservative due to using is lipophilicity substance, is easily layered in coolant system,
Cause entire coolant system unstable.
