Definitions
- the invention relates to a method and means for passivating iron and steel surfaces chemically with the aid of aqueous solutions which react weakly alkaline and contain a combination of certain corrosion-inhibiting substances.
- Passivation agents are also used as an additive to pressure baths, quenching water, such as for induction hardening, cooling circuits, such as in engine test benches, and also as hydraulic fluids.
- passivation A number of methods are known for passivation. For example, it can be carried out with oils or fats or also corresponding plastic emulsions, although undesirable layers often form. It is therefore often advisable to passivate the metal surfaces with aqueous solutions that contain appropriate chemical additives.
- Such corrosion inhibiting passivating agents for iron surfaces are, for example, alkali nitrites, alkali chromates, soaps, benzoates and alkanolamines. Alkanol amide salts of maleic acid have also been used for the passivation of iron and steel surfaces (see; e.g. EP-A-0002780).
- Suitable maleic acid monoalkylamides are both amides with straight-chain and branched alkyl radicals having 6 to 14 carbon atoms, preferably having 8 to 10 carbon atoms.
- Suitable alkanolamines are short-chain compounds such as mono-, di- and triisopropanolamine, n-propanolamine, N, N, N ', N'-tetrakis (2-hydroxyethyl) ethylenediamine and preferably mono-, di- and triethanolamine, in particular as Mixture, into consideration.
- Suitable complexing phosphonic acids are: 1-hydroxyalkyl-1,1-diphosphonic acids, 1-aminoalkyl-1,1-diphosphonic acid, phosphonocarboxylic acids, such as in particular 2-phosphono-1,2,4-tricarboxylic acid and / or Phosphonic acids of the general formula in the means.
- 1-Hydroxyethane-1,1-diphosphonic acid, 2-phosphonobutane-1,2,4-tricarboxylic acid and nitrilotrimethylenephosphonic acid have preferably proven successful.
- the phosphonic acids can also be used as alkali salts or alkanolamine salts.
- the free phosphonic acids can also be added to the corresponding solutions. In such a case, an excess of alkanolamine in the solution can then be used to adjust the pH to 7.5 to 10.5.
- An essential feature of the combination according to the invention is the weight ratio of maleic acid monoalkylamide to alkanolamine, which should be 1 0.3 to 1:10 and preferably 1: to 1: 4.
- the weight ratio of maleic acid monoalkylamide to phosphonic acid is the process according to the invention 1: 0.01 to 1: 0.5 and preferably 1: 0.1 to 1: 0.5.
- a further increase in the addition of phosphonic acid is possible, but does not bring any additional synergistic effects.
- the pH of the solution from 7.5 to 10.5 which is suitable for carrying out the process is not already achieved by the alkalinity of the substances used, it can be adjusted by adding a small amount of alkali.
- the metal surfaces made of iron or steel can be treated at elevated temperatures between 30 and 100 ° C., but preferably at room temperature.
- the agents can also contain further substances.
- surfactants preferably nonionic low-foaming surfactants. Especially if cleaning is desired at the same time as the passivation or if greased or partially greased parts are to be treated in one operation.
- low-foaming nonionic surfactants the addition products of ethylene or propylene oxide onto polypropylene glycol or polyethylene glycol and addition products of ethylene and / or propylene oxide onto mono- or polyalcohols, mono- or polyamines, fatty acids, amides and alkylphenols with an alkyl radical of preferably 8 to 20, in particular 12 to 18 carbon atoms.
- the concentration in the aqueous passivation solution is between 0.005 to 0.3 percent by weight.
- agents according to the invention may also be expedient in some cases to add builders, which increase the action of the surfactants, to the agents according to the invention in order to enhance the cleaning action.
- builders which increase the action of the surfactants, to the agents according to the invention in order to enhance the cleaning action.
- Ortho- or polymer phosphates and / or borates should be mentioned in particular.
- a builder content in amounts of 0.2 to 2 percent by weight, based on the aqueous solution, is preferred.
- the agents according to the invention can also contain alkanolamine soaps of short-chain fatty acids - d. H. of fatty acids with 6 to 12 carbon atoms -, for example caprylic or isononanoic acid, which reinforce the corrosion protection effect in a manner known per se and act as a solubilizer and as a foam regulator.
- the solutions according to the invention may optionally also contain preservatives for preventing bacterial decomposition, such as chlorophenols, diphenyl derivatives, hexahydrotriazine derivatives and / or for non-ferrous metal inhibition, benztriazole, mercaptobenztriazole and lignin sulfonate in amounts of about 0.05 to 0.1 percent by weight.
- preservatives for preventing bacterial decomposition such as chlorophenols, diphenyl derivatives, hexahydrotriazine derivatives and / or for non-ferrous metal inhibition, benztriazole, mercaptobenztriazole and lignin sulfonate in amounts of about 0.05 to 0.1 percent by weight.
- agents used contain the components mentioned in the stated amounts. If desired, however, the corresponding agents can also be prepared in concentrated form in order to be diluted to the stated concentration immediately before use.
- the corrosion protection obtained with the solutions according to the invention is considerably higher than the sum of the properties of the individual substances and exceeds the passivating agents used hitherto.
- the outstanding corrosion protection properties of the method according to the invention were tested in the corrosion protection test according to DIN 51 360/2 with cast chips GG 30 at an exposure time of 2 hours.
- the test solutions were prepared at room temperature with 20 ° hard water.
- the pH of all test solutions was between 8.5 and 10.5; Test and comparison solution were adjusted to the same pH.
- the concentration of the respective combination was 1, 1.5 and 2% in the DIN tests.
- the comparative tests are listed under a) and the solutions according to the invention under b).
