Abstract

The invention discloses a water-free cooling liquid for an automobile engine. The water-free cooling liquid for the automobile engine is prepared from, by weight, 40-50 parts of ethylene glycol, 30-40 parts of propylene glycol, 5-8 parts of benzotriazole, 3-5 parts of 2-mercaptobenzothiazole, 1-3 parts of sodium benzoate, 0.5-1 part of sodium sebacate, 0.5-0.8 part of cinnamic acid, 0.5-0.8 part of sebacic acid, 1-2 parts of sodium oleate, 0.5-1 part of sodium molybdate, 5-8 parts of calcium chloride, 8-10 parts of dimethyl silicone oil, 0.01-0.05 part of borax, 0.3-0.5 part of triethanolamine oleic soap and 8-10 parts of carboxymethyl cellulose. The water-free cooling liquid for the automobile engine has a lower freezing point and a higher boiling point and has better metal corrosion prevention property, cavitation prevention property and scaling prevention property and long service life.

Description

technical field [0001] The invention belongs to the technical field of engine cooling, and in particular relates to an anhydrous coolant for an automobile engine. Background technique [0002] Coolant, also known as antifreeze, antifreeze, etc., is the cooling medium of the automobile circulating cooling system. Its main function is to protect the normal and good operation of the engine. It circulates in the engine water tank to achieve antifreeze, antiboiling, antirust and anticorrosion effects. , with the development of the automobile industry, the performance requirements of the engine are getting higher and higher, not only requires the coolant to have a lower freezing point and a higher boiling point, but also should have better metal corrosion resistance, anti-cavitation, anti-corrosion Fouling, and has a long service life and other comprehensive performance. According to domestic relevant data reports, in the maintenance work of the automobile engine in normal use, 6...
