BYD develops a new and excellent antifreeze coolant

The antifreeze coolant prevents the coolant from freezing during a cold season and bursts the radiator and freezes the engine block. Antifreeze is not only used in winter. It should be used throughout the year. In every normal maintenance of the car, the antifreeze must be changed every year.

At present, there are many antifreeze coolants on the market, but many of them have disadvantages such as low boiling point, easy evaporation loss, high freezing point, flammability, low freezing point, high cost, and high price. Recently, BYD Auto Co., Ltd. has claimed that it has developed an ideal antifreeze coolant and has obtained national patents. The researchers explained in more detail the preparation method of this antifreeze coolant, which was obtained by mixing ethylene glycol, water, sebacic acid, sodium silicate, cinnamic acid, mannitol and defoamer evenly. This type of antifreeze coolant The storage stability is better, and the inhibitory effect on aluminum corrosion is greatly improved. It has the characteristics of high boiling point, low foaming tendency, good viscosity-temperature performance, anti-corrosion and anti-scaling, etc. It is an ideal antifreeze coolant. Cinnamic acid plays a key role in the experimental preparation of this antifreeze coolant. This new product has been widely used in BYD Co., Ltd.
