Vehicle engine fluid

Abstract

The invention discloses a vehicle engine fluid, relating to an engine fluid for a vehicle engine cooling system. The vehicle engine fluid is composed of glycol, sodium stannate, sebacic acid, adipic acid, benzotriazole, sodium benzoate, sodium salicylate, 1-carboxyl-2-hexyl-5-(7-carboxyl)-hexamethylene-3-alkene, hydrolyzed polymaleic anhydride, silane coupling agent KH-550, bis-imidazoline, dye, sodium hydroxide, deionzied water and the like. The vehicle engine fluid has the advantages of good corrosion effect, stable property, excellent corrosion inhibition property, no precipitate and no toxicity, and is not easy to volatilize, can be well absorbed on the surface of metal so as to form an absorption film, and can effectively inhibit corrosion of an antifreeze solution on soldering tin; and the selected additive is cheap and available and has good economic benefits and social benefits, and the like. The vehicle engine fluid can be widely applied to a cooling system of a vehicle engine, especially is used as a vehicle antifreeze solution in a low-temperature region.

Description

A kind of automobile engine antifreeze technical field The invention belongs to the technical field of antifreeze, and in particular relates to the antifreeze of an automobile engine cooling system. Background technique Antifreeze (also known as coolant, antifreeze) is the cooling medium of the internal combustion engine circulating cooling system. It has excellent performances such as antifreezing in winter, anti-boiling in summer, anti-scale and anti-corrosion throughout the year. my country's research on antifreeze began in the 1970s, and products did not appear until the 1980s. Although it has developed rapidly, there is still a significant gap with similar foreign products. With the continuous improvement of environmental awareness and quality of life, people's demand for environmentally friendly and safe antifreeze is increasing year by year. In recent years, since more and more aluminum metal components are used in engine systems, such as aluminum cylinders, water ...
