Description
Technical field
The present invention relates to a kind of organic coolant, the organic coolant of more particularly to a kind of automobile engine and its preparation side
Method.
Background technology
Engine coolant, also known as anti-icing fluid, anti frozen liquid, water tank treasured etc..Major function is normally good for protection engine
Operation, circulates in engine water tank, plays antifreeze, anti-boiling, antirust, anticorrosion and other effects.
Engine coolant is made up of water, antifreezing agent, additive three parts, can be divided into alcohol by antifreeze component difference
The coolant of the types such as type, glycerol type, ethylene glycol type.Alcohol type coolant is to make antifreezing agent, price with ethanol (being commonly called as alcohol)
Cheaply, good fluidity, preparing process is simple, but boiling point is relatively low, easy evaporation loss, freezing point easily raise, are inflammable etc., gradual quilt
Eliminate；Glycerol type coolant boiling point is high, volatility is small, be not easy to catch fire, nontoxic, corrosivity is small, but reduce freezing point it is ineffective, into
This is high, expensive, and user is difficult to receive, and only a small number of Northern European countries are still using；Ethylene glycol type coolant is spent glycol
Make antifreezing agent, and add the composite additives such as a small amount of anti-foaming, anticorrosion and be formulated., can be with because ethylene glycol is soluble in water
Arbitrarily be made into the coolant of various freezing points, its minimum reachable -68 DEG C of freezing point, this coolant have boiling point is high, foam tendency is low,
Viscosity temperature characteristic is good, anti-corrosion and the features such as antiscale, is a kind of ideal coolant, at present both at home and abroad used in engine and
The coolant that in the market is sold nearly all is this ethylene glycol type coolant.
However, if ethylene glycol is met naked light, high fever or contacted with oxidant, there is the danger for causing combustion explosion.If meeting high fever,
Container internal pressure increases, and has the danger of cracking and blast.Meanwhile ethylene glycol has certain toxicity, inhalation poisoning is shown as repeatedly
Ictal faintness, and can have nystagmus, lymphocytosis.Acute poisoning divides three phases after oral：First stage is main
For central nervous system symptom, the lighter shows like ethylism, and severe one produces rapidly stupor twitch, last dead；Second stage,
Cardiopulmonary symptom is obvious, and several cases can have pulmonary edema, Bronchopneumonia, heart failure；Phase III is mainly shown as different journeys
Spend renal failure.Oral lethal dose of this product of people is estimated as 1.4ml/kg (1.56g/kg).It is in addition, Celsius 80 for a long time
For degree to working under 90 degrees Celsius, ethylene glycol can first be oxidized to glycolic, then be oxidized to oxalic acid, i.e. ethanedioic acid (oxalic acid), contain
There are 2 carboxyls.Oxalic acid and its accessory substance can first influence central nervous system, followed by heart, then influence kidney.As without appropriate
Treatment, death can be caused by absorbing excessive ethylene glycol.
Therefore, to find a kind of organic cooling liquid formulation of automobile engine can substitute ethylene glycol as the leading of coolant
Status, it is this area research staff's urgent need to solve the problem.
Therefore, a kind of organic cooling of automobile engine whether energy-conserving and environment-protective, also become weigh its performance important indicator.
