FIELD: chemistry.
SUBSTANCE: anticorrosion agent for working fluids of hydraulic systems contains the following in wt %: 5-80 of at least one fatty acid alkanol amide based on saturated or unsaturated fatty acids with 10-20 carbon atoms, 5-80 of at least one alcohol with 2-14 carbon atoms and 5-80 of at least one aromatic monocarboxylic acid or one aliphatic dicarboxylic acid with 10-12 carbon atoms. The water-miscible concentrate for working fluids of hydraulic systems based on water contains 2-20 wt %, preferably 5-15 wt % anticorrosion agent. In order to prepare working fluids of hydraulic systems, 1-20 % concentrate is mixed with 80-99 % water.
EFFECT: improved anticorrosion characteristics.
