PROCESS FOR THE PREPARATION OF RETARDING LIQUIDS BASED ON GLYCOL COMPOUNDS INHIBITED TO AVOID CORROSION OF METALS

摘要

The brake fluid described consists essentially of A) at least one glycol compound as the main component, B) at least one inhibitor for fluids based on glycol compounds and C) an effective quantity of a mixture of acidic phosphate esters which essentially consists of monophosphate esters and diphosphate esters and has been obtained by reacting a phosphorus-containing compound with a monohydric alcohol and a polyol. The novel brake fluid shows high corrosion inhibition, in particular towards the metal tin.
