Problems solved by technology
The characteristic of antifreeze is that it is cheap but very corrosive and needs to be replaced every year; the service life of the coolant is 2 years, the price is high and it is corrosive at the same time. Over time, the internal waterway and water tank of the engine will be damaged due to corrosion. Although it is easy to take, after a long time of use, a large amount of scale will be generated inside the engine, which will block the waterway
After the above cooling medium is used for a long time, a large number of engines will generate high temperature, which will damage the engine

Embodiment Construction
[0019] Non-limiting examples are described as follows:
[0020] Put 94kg of ethylene glycol, 1kg of sebacic acid, and 1.2kg of n-octanoic acid into the preparation kettle, start stirring and raise the temperature to 85-95°C, and keep it warm for half an hour; take 1kg of potassium hydroxide and 2.2kg of deionized water to prepare potassium hydroxide Put the solution into the preparation kettle under stirring, and finally add 0.6 kg of urotropine, stir evenly, and then cool to obtain. The pH value of the cooling liquid is 7.8 to 8.2.

The invention relates to an energy-saving cooling fluid which takes glycol as a base material, and has the following components according to mass percentage: 92 to 95 of the glycol, 1 to 3 of deionized water, 0.5 to 1.5 of decanedioic acid, 0.6 to 2 of n-octanoic acid, 0.4 to 1.5 of potassium hydroxide, and 0.3 to 0.8 of methenamine. The cooling fluid has low freezing point, wide boiling spread, excellent heat conductivility at high temperature, and energy-saving efficiency, prevents frozen injury and occurrence of steam blocking layer when the engine works, improves the thermal equilibrium temperature when the engine works, with the fuel completely combusted, reduces tail gas discharge, and obviously promotes the power.
Description
1. Technical field [0001] The invention relates to a cooling liquid for an automobile engine (engine), in particular to an energy-saving cooling liquid. 2. Background technology [0002] At present, all vehicles basically use antifreeze, coolant and other products, mostly water. The characteristic of antifreeze is that it is cheap but very corrosive and needs to be replaced every year; the service life of the coolant is 2 years, the price is high and it is corrosive at the same time. Over time, the internal waterway and water tank of the engine will be damaged due to corrosion. Although it is easy to take, after a long time of use, a large amount of scale will be generated inside the engine, which will block the waterway. After the above cooling medium is used for a long time, a large number of engines will generate high temperature, which will damage the engine. 3. Contents of the invention [0003] The invention aims to provide an energy-saving cooling liquid for autom...
