Definitions

  • the invention relates to a process for the preparation of sol-gel corrosion protection coatings for solar absorbers.
  • Such solar absorber surfaces are made of thin layers of cermet materials deposited on a metallic substrate.
  • mercaptosilanes have also been used mainly for the production of protective films on aluminum alloys, but they have not been recognized as effective corrosion inhibitors for spectrally selective surfaces.
  • the object of the present invention is the development of a method of the type mentioned for the production of ultra-thin, ie from 1 to 500 nm thick coatings, which on the one hand ensure adequate corrosion protection, but on the other hand, do not degrade the optical properties of solar selective surfaces.
  • the method according to the invention comprises mixing at least one mercaptosilane dissolved in an organic solvent with water and an acid catalyst, applying the resulting sol mixture to a substrate for an exposure time sufficient to form an at least monomolecular film on the substrate, the separation of sol and film-coated substrate and a subsequent drying and a final heat treatment.
  • the initial mixing of the mercaptosilane can also be carried out with at least one further silane.
  • mercaptosilane-based sol-gel corrosion protection films preferably having a thickness of between 0.5 and 500 nm
  • various metallic substrates including metallic films provided with optically effective layer systems on their surface selective cermet layers, such as chromoxynitride, titanium oxynitride or titanium-aluminum oxynitride, used in solar heat applications.
  • optically effective layer systems on their surface selective cermet layers, such as chromoxynitride, titanium oxynitride or titanium-aluminum oxynitride, used in solar heat applications.
  • chromoxynitride titanium oxynitride or titanium-aluminum oxynitride
  • solar heat absorber surfaces Most notable is the application of these coatings to solar heat absorber surfaces.
  • the coatings according to the invention advantageously ensure very good corrosion protection and do not impair the thermal emissivity of these surfaces, which can increase by at most a few percentage points, with the solar absorption capacity even increasing.
  • Fig. 4 Photos of exposed in Salzsprühhuntn, different anti-corrosive treated, aluminum samples.
  • the production of nanodynic anti-corrosion films - in particular with a thickness in the range from 0.5 to 500 nm - can be carried out on solar, spectrally selective surfaces, as are typical of the solar absorbers commercially available under the names Sunselect, TiNOX and Eta plus, which made of sheet metal, such as aluminum, copper, iron or their alloys, and with a, for example, chromium and titanium oxynitride existing cermet absorber layer and optionally further, z.
  • Sunselect is an absorber material in which a multilayer optical system is located on a copper carrier, the uppermost layer of which is an antireflection coating made of tin oxide SnO 2.
  • An immediately underlying layer is an absorbing layer consisting of chromium oxynitride CrNO x . Under this layer, in turn, lies a metallic IR reflection layer. The various layers are sputtered over a large area onto the metal substrate.
  • Fig. 1 shows photographs of three differently protected 5 cm x 5 cm samples exposed in a chamber to a salt spray test according to ASTM B 117-07a: ("Standard Practice for Operating Salt Spray (Fog) Apparatus").
  • the left sample (a) had an unprotected cermet surface already showing corrosion after 24 hours
  • the middle sample (b) had a cermet surface protected by a known non-inventive coating and exhibiting corrosion after 120 hours of corrosion, which was prepared on the basis of polyphenylsilsesquioxane
  • the right sample (c) had a cermet surface protected with 3-mercaptopropyltrimethoxysilane sol (MPTMS), which showed no signs of corrosion even after 480 hours. It can be seen that protection with MPTMS significantly improves the corrosion stability in a salt spray chamber.
  • FIG. 2 shows potentiodynamic curves of unprotected (curve a) and MPTMS-protected Sunselect (curve b).
  • the potentiodynamic measurements were carried out with the potentiostat galvanostat device AUTOLAB PGSTAT30, using a three-electrode cell K0235 from Princton Applied Research.
  • the sample to be examined was switched as a working electrode, while a platinum grid was used as the counter electrode and Ag / AgCl as the reference electrode.
  • potential difference polarization curves were recorded at a scanning speed of 0.5 mV / s in a 0.5 molar NaCl electrolyte.
  • the coating causes it to decrease the corrosion current and a shift of the corrosion potential to more negative values, indicating that MPTMS acts as a mixed inhibitor (anodic and cathodic inhibitor) with a more pronounced cathodic efficiency.
  • FIG. 3 shows the hemispherical reflection spectrum of protected (curve a) and unshielded Sunselect (curve b) with calculated values of the solar absorptivity ⁇ s and the thermal emissivity ⁇ j.
  • the optical properties of the samples were measured by measuring the IR absorption and reflection spectra on samples with a minimum size of 5 cm * 5 cm.
  • Visible (VIS) and near-infrared (NIR) reflectance spectra were determined with the Perkin Elmer Lambda 950 UVA / is / NIR device using an integrating sphere (150 mm module), while the mid IR spectra were determined were determined using a Bruker IFS 66 / S spectrometer equipped with an integrating sphere (OPTOSOL).
  • OPSOL integrating sphere
  • gold plate was used as standard for the diffuse reflection.
  • the values of the solar absorptivity ⁇ s and the thermal emissivity ⁇ j were calculated according to a standard method described in M. Kohl, G.
  • the curve comparison indicates no significant change in selectivity through the coating.
  • the increase in the thermal emissivity of a sample protected according to the invention was less than 0.35, typically less than 0.10. An increase of less than 0.05 could be achieved if one were to pay even more attention to a corresponding preparation of the coating according to the invention.
  • the preservation of selectivity on the one hand, and the increase in corrosion stability, on the other hand, are the most important effects of the present invention.
  • the inventive method for increasing the corrosion protection is also suitable for bare metallic substrates such as copper, aluminum, iron and their alloys.
  • Fig. 4 where photos of AI 2024-T3 samples of size 5 cm * 5 cm are shown, which are also in salt spray chambers a salt spray test after the o. Standard ASTM B 117-07a were subjected. The exposure of the samples took place over different periods.
  • the upper row shows samples not adequately protected by a layer based on isobutyltrimethoxysilane according to the invention, while the photos in the lower row represent samples which were protected according to the invention with a sol containing MPTMS according to Embodiment 3 described below. It can be seen that the samples protected according to the invention show excellent corrosion stability in the salt spray chamber, corrosion only beginning after 13 days, whereas in comparison the samples with the coating containing no MPTMS were completely corroded after one day.
  • an organic solvent preferably an aliphatic alcohol, in particular ethanol, or else 3-butoxy-2-propanol or propylene glycol monobutyl ether;
  • an acid catalyst any compound whose aqueous solution has a pH between 0-6.9 selected from the group consisting of HCl, HBr, HI, HNO 3 , H 2 SO 4 , H 3 PO 4 , ants -, acetic, propionic, butyric, salicylic, trifluoroacetic, trichloroacetic, trifluoromethanesulfonic and methanesulfonic acid, so that the final concentration is 1 .mu.mol to 1 mmol;
  • the mixture is prepared in such a way that only monomeric and oligomeric species are formed by the SoI gel method;
  • the sol consists only of fully hydrolyzed monomers and dimers of very low Amount of fully hydrolyzed linear thmeres.
  • the regulation of the hydrolysis / condensation ratio is achieved with an appropriate amount of added water. Therefore, it is advantageous to use more than one equivalent of water for each hydrolyzable alkoxy group.
  • the mixing time for preparing the sol-mixture can be in the range of one minute to seven days.
  • the substrate is immersed in the sol mixture so long that it can soak up in the event that it has a porous surface, the immersion time being sufficient for the sol to be one, preferably virtually self-forming, at least monomolecular Gel layer formed on the surface of the substrate.
  • Commercial solar absorber surfaces are porous, so this step is of great importance. If the SoI can penetrate deeply into this porous structure, better corrosion protection is possible.
  • the formation of a layer that preferably bonds itself together so that the condensation reaction proceeds and the penetration of the sol can take place in particular within a period in the range of one second to five hours, wherein the immersion time is preferably more than five seconds and less than four hours should be.
  • the removal of the sol can be done in a number of ways, but it should be understood that the rate at which the removal of the sol occurs significantly affects the thickness and anti-corrosive effect of the later protective layer. Too thick a film can degrade the solar spectral selectivity of the sample. Therefore, the speed of the sample removal from the sol should be between 0.1 cm / s and 100 cm / s, whereby in a discontinuous process the sample can be pulled out of the sol, especially on a laboratory scale by hand.
  • the sample is then after removal of the sol or from the sol over a period in the range between one second and two days, preferably in Range between one second and 36 hours, air dried to remove the solvents.
  • the sample is subjected to a heat treatment, also referred to as baking, to complete the condensation and achieve complete crosslinking.

  • the coating of samples may be accomplished using different techniques for applying the sol to the substrate. If the substrate is sheet-shaped, it can be coated by means of the above-described - also referred to as a batch process - dip coating process.
  • the substrate is in the form of a tape wound in roll form - a so-called coil - because then a continuous coating process can be used.
  • the substrate strip is preferably guided from a coil consisting of uncoated substrate by means of a transport cylinder arrangement through a container which contains the sol mixture for producing the coating, wherein the intended immersion time, which may correspond to that of the batch process, is maintained , Thereafter, the tape is pulled out of the bath, dried by blowing with air and then passed through an oven where it is heated to complete the condensation. Finally, it is cooled to room temperature and rolled up into a coil of coated substrate.
