Definitions

  • the invention relates to a mixture of a zinc alkanolamine mixed salt of phosphonobutane-tricarboxylic acid with an alkanolamine salt of a di- and / or branched monocarboxylic acid, their use as an anti-corrosion additive, containing anti-corrosion additives or consisting of these mixtures and press water, hydraulic fluid or cooling lubricant containing this mixture.
  • Water-soluble corrosion protection additives are required for press water, water-soluble hydraulic fluids, that are flame-retardant hydraulic fluids such as HF-A, HF-B and HF-C, and water-miscible and water-soluble cooling lubricants for metalworking.
  • the water-miscible and water-soluble cooling lubricants are used in the chipless and span metalworking, such as rolling, drawing, punching, compression molding, drilling, grinding, sawing, milling, broaching, cutting, honing, lapping and polishing.
  • the water-miscible cooling lubricants are emulsions, mostly oil-in-water emulsions.
  • Water-soluble cooling lubricants are synthetic, semi-synthetic and chemical cooling lubricants, e.g. Glycols, their oligomers and polymers, alkoxylates and dispersions and solutions with inorganic substances.
  • the corrosion inhibitors used to date such as nitrites, chromates, salts of p-tertiary butylbenzoic acid, mono- and dicarboxylic acids, such as isononanoic acid and sebacic acid, and salts of sulfonamidocarboxylic acid and sarcosine may in some cases no longer be used due to toxic and environmental reasons, or are no longer used for odor reasons or unsatisfactory due to insufficient spectrum of activity as well as foam and sticking tendency.
  • Salts of 2-phosphonobutane-1,2,4-tricarboxylic acid have been proposed as corrosion inhibitors for agitated aqueous systems, such as cooling circuits, in DE-OS 2 225 645.
  • zinc ions significantly improve the corrosion protection effect.
  • DE-OS 2 333 353 describes further synergistic effects of 2-phosphono-butane-1,2,4-tricarboxylic acid with benzimidazole derivatives, polyvinylpyrrolidones, polyetylenimines and lignin sulfonates.
  • the invention thus relates to a mixture of a phosphonobutane-tricarboxylic acid-Zn-alkanolamine mixed salt with an alkanolamine salt of a dicarboxylic acid and / or a branched monocarboxylic acid having 8 to 12 carbon atoms, the alkanolamine salts of the carboxylic acid surprisingly resulting in a synergistic effect on the effectiveness of the mixture increase considerably without disadvantage of the further requirements.
  • the mixture according to the invention preferably consists of 1 mol of 2-phosphonobutane-1,2,4-tricarboxylic acid salt and 0.1 to 1 mol, particularly preferably 0.5 mol of an alkanolamine salt of a dicarboxylic acid and / or branched monocarboxylic acid with 8-12 C- Atoms, especially 9-10 carbon atoms.
  • a 1.5% by weight solution in water should have a pH of 7.5 to 10, preferably 8 to 9.
  • the phosphonobutane tricarboxylic acid salt can be prepared as follows:
  • the equimolar excess of alkanolamine results from the complex binding of the alkanoamine to the Zn ion.
  • the alkanolamine salts of the carboxylic acids are prepared by neutralizing 1 mol of alkanolamine or 1 mol of dicarboxylic acid with 1 mol or 2 mol of alkanolamine.
  • the mixture according to the invention can be obtained by 48.8-89.5 parts by weight of the 2-phosphonobutane-1,2,4-tricarboxylic acid-Zn-alkanolamine mixed salt with 1.5-51.2 parts by weight. Mix parts of the mono and / or dicarboxylic acid alkanolamine salt and adjust to the necessary pH by adding a further 4.7 to 98.2 parts by weight of alkanolamine.
  • the preparation can also be carried out simultaneously by reacting 1 mol of 2-phosphonobutane-1,2,4-tricarboxylic acid with 0.1-1 mol, preferably 0.5 mol, of ZnO at 80-90 ° C. with stirring and after filtration any turbidity is neutralized with the total amount of 5-8 moles of alkanolamine. 0.1 to 1 mol of the mono- and / or dicarboxylic acid are then stirred into this solution.
  • alkanolamines suitable for salt formation are commercially available products, such as. Monoethanolamine, diethanolamine, triethanolamine, monopropanolamine, dipropanolamine and tripropanolamine, preferably diethanolamine.
  • Suitable mono- or dicarboxylic acids are, for example. Isononanoic acid, isodecanoic acid, isododecanoic acid, suberic acid, trimethyladipic acid, azelaic acid, sebacic acid and isosebacic acid, preferably sebacic acid.
  • the corrosion protection additive according to the invention can be used in a concentration of 0.1-10% by weight, preferably 0.5-4% by weight, based on the total amount of press water, hydraulic fluid or cooling lubricant, depending on the water quality and requirements.
  • a combination with other suitable corrosion inhibitors and other active substances is possible.
  • Other active ingredients are biocides, emulsifiers, antiwear and high pressure additives, non-ferrous metal deactivators, antioxidants, foam suppressants and dyes.
  • Product D shows that the synergistic effects, such as those found in DE-OS 2 333 353 for agitated aqueous systems, cannot be transferred to use in cooling lubricants.
