摘要
The present invention relates to an antifreeze composition containing a water-soluble liquid alcohol and a corrosion inhibitor system comprising (a) a mixture of at least two aromatic or aliphatic dicarboxylic acids, or of at least two salts of the said acids, (b) at least one 1,3-diazole chosen from imidazole, benzimidazole, imidazoline and hydrocarbon derivatives thereof, and (c) at least one triazole compound. The aqueous fluids containing the said composition have excellent anticorrosive properties and heat stability over long periods of time, in particular when the fluids are used as heat transfer fluids at temperatures above 150° C.
