Abstract

The invention discloses automobile coolant, which is prepared from the following raw material formula components in parts by weight: 12-16 parts of ethylene glycol, 10-15 parts of salicylic acid, 9-13 parts of tolylthiourea, 12-18 parts of para-thiocresol, 7-11 parts of sodium nitrate, 7-10 parts of propyl sulfide, 8-14 parts of diamyl amine, 5-8 parts of sodium phosphate, 6-10 parts of sodium silicate, 10-15 parts of polyoxypropylene oxyethylene glycol ether, 2-3 parts of dimethicone, 2-3 parts of hydroxyl silicone oil, 3-4 parts of polydimethylsiloxane, 4-5 parts of butanol, 1-3 parts of methylene blue and 100-140 parts of deionized water. Therefore, the automobile coolant has the advantages of being low in cost, nonvolatile, safe and reliable.

Description

technical field [0001] The invention relates to the technical field of coolant, in particular to an automobile coolant. Background technique [0002] Coolant is the cooling medium of the engine circulating cooling system, and its main function is to protect the normal operation of the engine; automotive engine coolant has gone through several generations of development, such as water, inorganic salt type, methanol, ethanol type, ethylene glycol type, etc.; With the development of the automobile industry, the engine is developing towards high load and high technology, and the working state of the cooling system directly affects the normal operation of the engine and the service life of the vehicle. Therefore, engine coolant not only requires a lower freezing point and a higher boiling point, but also has excellent metal corrosion inhibition, anti-cavitation, anti-scaling properties, and is environmentally friendly and has a long service life. and other aspects of comprehensi...
