Engine anhydrous cooling liquid and preparation method thereof

Abstract

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.

Description

technical field [0001] The invention relates to an engine coolant, in particular to a waterless engine coolant and a preparation method thereof. Background technique [0002] The engine is the core component of the car. The power of the car and the driving of the car air conditioner are all borne by the engine. However, the efficiency of the engine with too high temperature will be reduced or even damaged, and the engine with too low temperature will increase fuel consumption. Therefore, the cooling system is the most effective guarantee to ensure the normal operation of the engine at normal operating temperature. [0003] With the continuous expansion of the engine market, the coolant used in conjunction with it has also been greatly developed. At present, the coolants on the market are basically water-containing coolants (water, ethylene glycol). Water has a high freezing point and freezes at 0°C, and has a low boiling point and "boils" at 100°C. Icing will freeze the cy...

Problems solved by technology

However, although the cooling system can be directly used in theory without water, the actual situation is that in the assembly of new cars, due to factors such as sales costs and post-maintenance industry chain profits, few domestic and foreign models are equipped There is no water coolant, so when some users need to replace it in the later maintenance, due to the complex structure of the cooling system, it is impossible to completely eliminate the old water-containing antifreeze, so the remaining part will destroy the simple propylene glycol, causing uncontrollable destructiveness , so the existing propylene glycol anhydrous coolant does not have a wide range of adaptability, and cannot be perfectly compatible with the residual water-containing antifreeze

Secondly, the existing propylene glycol anhydrous coolants at home and abroad are not toned in order to advertise the difference from water-containing coolants, resulting in leaks in the cooling system that cannot be detected in advance, resulting in minor hidden dangers and major failures
