Definitions
- the present invention relates to a functional fluid corrosion inhibitor, a water-miscible water-based functional fluid-containing concentrate containing this corrosion inhibitor, and the use thereof.
- HFA fluids are liquids used as lubricants, abrasives, coolants and lubricants for metal forming and metal cutting, and more particularly as hydraulic fluids, namely, hydraulic fluids.
- These water-based functional fluids are also referred to as HFA fluids or HFA hydraulic fluids.
- HFA hydraulic fluids are used in particular in the hydraulic longwall mining systems. They are prepared on site by mixing from 1 to 20% by weight of a water-miscible concentrate containing the necessary active ingredients with correspondingly 99 to 80% by weight of water. The concentrates may contain as lubricants, synthetic products or those based on mineral oil.
- the HFA hydraulic fluid obtained is either an emulsion (HFAE), including a microemulsion, with mineral or synthetic oil, or solutions (HFAS).
- HFAE emulsion
- HFAS HFAS
- Such HFA hydraulic fluids have the viscosity of water and can be used in a temperature range of + 5 ° C to + 55 ° C.
- Corrosion inhibitors and other auxiliaries such as animal, vegetable, mineral and / or synthetic oils, fats, oil or fat components as lubricants, fatty alcohols, biocides, fungicides, complexing agents, heavy metal inhibitors, nonionic or anionic emulsifiers, dispersants and defoamers.
- a water-miscible coolant concentrate known which contains natural or synthetic mineral oils, emulsifiers, solubilizers, preservatives, metal inhibitors and other conventional additives and having a pH of less than 7.7 for the purpose of ensuring skin compatibility.
- this concentrate may contain reaction products of boric acid with primary or tertiary alkanolamines, ethoxylated or propoxylated fatty acids or fatty acid alkanolamides, phosphoric acid esters, triazoles of the thiadiazoles either alone or in combination.
- a water-mixed cooling lubricant can be produced with these concentrates, whose pH is as close to the neutral point and still does not lead to rusting of metal parts that have been processed with an aqueous solution of the coolant, these assets Concentrates and the functional fluids produced therewith based on water, especially with regard to their corrosion effect unsatisfactory.
- these waterborne coolants when in contact with metal surfaces for extended periods of time, such as when used in hydraulic equipment, can result in corrosion of the exposed metal surfaces, particularly by pitting and the deposition of undesirable deposits.
- EP-A-591 771 describes lubricant compositions for metal forming comprising as lubricating component an ethoxylated fatty amine or amide, an amine or amide salt, an Imidazolinsalz, a polyalkylene glycol or lanolin, as a film-forming component one or more vinyl or acrylic polymers, cellulose ethers, fatty alcohols or waxes and anticorrosive a mixture of mono and dicarboxylic acids, a fatty acid ethanolamide or a glycol derivative.
- lubricating component an ethoxylated fatty amine or amide, an amine or amide salt, an Imidazolinsalz, a polyalkylene glycol or lanolin, as a film-forming component one or more vinyl or acrylic polymers, cellulose ethers, fatty alcohols or waxes and anticorrosive a mixture of mono and dicarboxylic acids, a fatty acid ethanolamide or a glycol derivative.

- the method of corrosion testing by means of this crevice corrosion test has been published in Johnsonauf 138 (2002) No. 5, pages 208-212 , The method consists in that the pressure fluid or hydraulic fluid to be tested in a defined punch unit (piston-cylinder) is stored under purely static conditions for 21 days at a humidity of 95% and a test temperature of 35 ° C.
- the gap region is formed between the cylinder inner surface and a bronze part located on the piston. On the bronze part, a commercially available sealing ring is mounted.
- the stamp unit After a contact time with the liquid to be tested for 21 days, the stamp unit is dismantled and examined the gap area on the cylinder inner surface with respect to a corrosion formation.
- this crevice corrosion test shows that inadequate corrosion protection in addition to a pitting and cratering also deposit-like, very different color corrosion products are deposited in the gap area on the cylinder surface. If these deposits are found in the gap area of the sealing ring on the cylinder surface, they are usually also found on the sealing ring surface and the bronze surface. In particular, smaller particles collect on the sealing lip, which are responsible for a linear corrosion in the circumferential direction of the cylinder surface.
- crevice corrosion reference should be made to the standard DIN EN ISO 8044-3.17.
- Water-mixable concentrates are first prepared from the constituents indicated in the following Tables 1 to 3, which are then mixed in a ratio of 2 parts by weight concentrate with 98 parts by weight of water, to form a HFA hydraulic fluid, which is examined in the above-mentioned crevice corrosion test.
- water is initially introduced, after which potassium hydroxide is added and dissolved with stirring.
- the particular acids used such as sebacic acid, dodecanedioic acid, undecanedioic acid or in Comparative Example E neodecanoic acid added, and it is stirred at a temperature of 50 ° C until the pH of the mixture is 7.
- sodium citrate and monoethanolamine are added and the mixture is allowed to cool with stirring to 25 ° C.
- a portion of the aliphatic hydrocarbon lubricant (50%) is heated in a separate vessel and then the fatty acid alkanolamides, sodium petroleum sulfonate is added with stirring and then the remaining aliphatic hydrocarbon followed by the remaining ingredients.
- the mixture is then thoroughly mixed and, with stirring, the water-containing mixture obtained in the first stage is added to the aliphatic hydrocarbon-based mixture.
- This gives a light brown, clear, slightly viscous concentrate, which is then mixed with water to form a water-based functional fluid (HFA hydraulic fluid) containing 2 wt .-% of the concentrate and 98 wt .-% water.
- HFA hydraulic fluid water-based functional fluid
- This HFA hydraulic fluid is introduced into the gap area of the stamp unit for the crevice corrosion test and statically stored for 21 days at a humidity of 95% and a temperature of 35 ° C.
- the tester is examined with regard to the sludge in the bottom area of the outer tube, in the gap area and bronze piston area and deposits before cleaning in the inner tube and the outer tube and on tarnish after cleaning in the inner tube and in the outer tube and on solid deposits on the inner surface of the cylinder and in the gap region of the cylinder and on the surface of the bronze piston examined.
- the HFA hydraulic fluids of the present invention do not give rise to any corrosion effects, while the products of Comparative Examples A to B do not pass the corrosion test according to DSK Standard N 762 830, since both deposits are present the cleaning on the cylinder notice, as well as solid deposits in the gap region of the cylinder and a line-shaped corrosion in the circumferential direction in the gap region of the cylinder.
- Comparative Example E reveals that a water-based hydraulic fluid containing neodecanoic acid, ie a C 10 monocarboxylic acid, develops considerable corrosive effects and consequently unsuitable for use as HFA hydraulic fluid, while the corrosion inhibitor according to the invention and the HFA hydraulic fluid containing it , which differs from the product of the prior art by the inventive selection of the particular aliphatic dicarboxylic acids, shows no corrosive action and readily for the Use in, for example, hydraulic longwall mining systems suitable for mining.
