The invention discloses an engine
anhydrous cooling liquid and a preparation method thereof, wherein the engine
anhydrous cooling liquid comprises the following raw materials by the weight percentage:60-70% of
propylene glycol, 25-30% of
ethylene glycol, 3-4% of 1,2-aminoazophenylene, 1-2% of
sodium nitrate, 2-3% of
glycerol, 1-2% of
triethanolamine, 0.5-1.5% of
sodium hydroxide, and 0.1-1% of apigment. The
anhydrous cooling liquid has the
freezing point lower than -52 DEG C and the
boiling point more than 190 DEG C and has a large thermal safe space, so with the use of the product, the anhydrous cooling liquid can maintain a good state for operation, adequate power is maintained,
noise is reduced, a water tank does not produce 'boiling', and cylinder
score is not generated. With use ofthe anhydrous cooling liquid, zero
corrosion can be achieved, no water
rust is generated, cleaning and repair are not needed forever, and boiling, cylinder
score, water tank blocking, water
rust, water scale,
corrosion and
cavitation corrosion, engine fatigue,
nausea, explosive vibration, precombustion, large
noise, unstable
idle speed,
cylinder pressure reduction, insufficient power,
oil consumption increase and large
exhaust gas emission
smoke and other phenomena are thoroughly eliminated.
