Abstract

The invention provides a multifunctional car water tank antifreeze fluid. The antifreeze fluid comprises the following components, by weight, 50-65 parts of alcohols, 30-45 parts of deionized water and 1-5 parts of an additive. The freezing point of the antifreeze fluid can reach -40DEG C or lower, so north cold weather demands can be satisfied; and the boiling point of the antifreeze fluid can reach 140DEG C or more, so an overheat case does not appear even in hot summer, thereby the car driving safety and the normal operation of a cooling system are guaranteed. The two used alcohols are nontoxic and harmless, so the damages of harmful substances to human bodies are eliminated, and environmental protection and safety are realized. The antifreeze fluid has the anticorrosion, antirust and antiscale effects, and can effectively protect the car cooling system, so the service life of the cooling system is prolonged.

Description

technical field [0001] The invention belongs to an antifreeze product, in particular to an antifreeze liquid for an automobile water tank. Background technique [0002] With the expansion of automobile ownership, the market demand for automobile antifreeze, which is necessary for daily maintenance of automobiles, is also gradually increasing. Antifreeze is mainly composed of water and organic substances that can lower the freezing point. The main component of existing antifreeze is mostly ethylene glycol, but ethylene glycol is toxic. Long-term use can inhibit the central nervous system of the human body, especially for the eyes. The cornea is an irritant, especially for workers who produce antifreeze. [0003] Therefore, there is a need for a safe and non-toxic antifreeze formula that can reach the freezing point. In addition, a good improvement method is also needed for the phenomenon that the antifreeze corrodes the water tank and is easy to scale, resulting in low work...
