Description
Technical field
The invention belongs to Antifreezing/Cooling Fluids for Automotives technical field, in particular to a kind of long-acting antifreeze cooling of synthetic additive type
Liquid and preparation method.
Background technique
In recent years, with the development of the automobile industry, automobile engine technology develops rapidly, and anti-freeze cooling liquid is by car engine
Composition and its material influence it is very big, the requirement to anti-icing fluid is increasingly harsh, thus the remodeling of anti-freeze cooling liquid is regenerated also just
Accelerating, in addition, Modern Automobile Engine power increase and water tank and radiator small, anti-freeze cooling liquid amount subtract
Less, heat exchange area reduces, and causes the temperature of the anti-freeze cooling liquid of engine and cycle-index to increase, thus it requires antifreeze cooling
Liquid has durable high-temp anti-corrosion performance.
It is well known that automobile engine cooling liquid is the circulating heat transfer medium in car water engine-cooling system,
It is to make engine work, the essential component part of operating, directly affects the service life of automobile；Anti-freeze cooling liquid
Major function be: take away the heat that engine generates at work；It prevents from boiling at high temperature and freeze under low temperature；Protection hair
Motivation cooling system metalwork prevents corrosion, corrosion and cavitation erosion；Prevent engine-cooling system from influencing to conduct heat because of fouling
Efficiency.
Current anti-freeze cooling liquid product comprehensive performance existing on the market is still not ideal enough, in order to guarantee engine cool system
Unite each metal parts in use not be cooled corrosion, usually in coolant liquid be added nitrate, nitrite, boric acid
Traditional inorganic salts corrosion inhibiter such as salt, silicate, phosphate, to guarantee the materials such as the copper in cooling system, steel, scolding tin, cast iron
It is not corroded and can be used for a long time；But these are all and to be easy to produce metal erosion to human body and the harmful substance of environment,
Corrode the metalwork of engine-cooling system, formulation stability is poor, and these traditional inorganic salts corrosion inhibiter are very for a long time
It is easy to form fouling and precipitating in conjunction with the calcium and magnesium ion in hard water, influences the work of the radiating efficiency and engine of radiator
Stability；Entire cooling recirculation system can be also blocked when precipitating more.The stability of some corrosion inhibiter such as silicate at low temperature
Also poor, it is easy that precipitating is precipitated, influences anti-corrosion effect.
The existing patent for consulting domestic most anti-freeze cooling liquid is essentially all using traditional inorganic salts inhibition
Agent is aided with a small amount of organic inhibitor by inorganic salts corrosion inhibiter, such as CN 104804713 A, CN 101955755 A, CN
01131412.5, although such product has certain corrosion protection effect, but for a long time, be especially to cast aluminium metal,
After contacting with aluminum metal, aluminium discoloration can be made to black, it is poor to the protecting effect of aluminium in cooling system, it is difficult that full aluminium is suitble to start
Machine, and the air pocket of cylinder sleeve of automobile engine is protected poor.
