Description
Technical field
The present invention relates to a kind of engine coolant, belong to the chemical composition technical field.
Technical background
Water uses as the engine coolant of motor car engine always.But the freezing point height, when temperature was lower than 0 ℃, water freezing increased volume, causes water tank or the spalling of cooling system pipeline easily; Be dissolved in metallic salt in the water back that is heated and form incrustation scale, reduce heat transfer efficiency; Water also can cause the metallic corrosion of engine-cooling system.People adopt the aqueous solution (as calcium chloride, magnesium chloride, SODIUMNITRATE, Sodium Nitrite) of salt can reduce freezing point to below-30 ℃, but can not solve the metallic corrosion problem.Afterwards, it is found that the performance of aqueous glycol solution is good, freezing point can reach below-60 ℃ when certain ratio, and boiling point is more than 110 ℃, and it can not damage rubber hose, adds behind the rust-preventive agent not corroding metal, and price is relatively cheap, does not have bad smell.Therefore this liquid extensively adopts the frostproofer as the engine coolant of automobile cooling system at present.
The additive formulations technology is the core of engine coolant technology.
Because silicate is the special corrosion inhibitor of aluminium and aluminium alloy,, the good corrosionproof protection of aluminium is become both at home and abroad research emphasis to automobile engine cooling liquid along with the widespread use of aluminium alloy at car engine cooling system.Simultaneously, the chemical substance that contains harm environment such as amine substance, nitrite, phosphoric acid salt, imidazoles and human health in not wishing to fill a prescription.Conventional inorganic silicate is that antifreeze formulations is arisen at the historic moment, but because the silicate instability, gel is separated out and is formed precipitation easily, and use is restricted.
External in order to solve the problem of this respect, brought into use full organic acid type to send out engine coolant.And full organic acid type engine coolant is because the production cost height, and easily produces cavitation corrosion and use and be subjected to certain limitation.
