Definitions
- the invention relates to an object with an easily cleanable surface by means of a double coating with a hydrophobic outer layer having a component which reacts with free OH groups and an inner inorganic sol-gel layer.
- Such objects can consist of ceramic material, such as tiles, sanitary ceramic products or can be enamels, e.g. Oven muffles, metals such as Stainless steel or plastics.
- a preferred application are objects made of glass or glass ceramic, such as oven inner panes or transparent fireplace doors, which are exposed to high temperatures and / or heavy soiling and must be cleaned continuously so that they can fully perform their function.
- the invention further relates to a method for producing such coated articles.
- Hydrophobic surfaces can be created in different ways.
- a layer consisting of an inorganic-organic nanoparticle network can be crosslinked thermally or with UV light via unsaturated organic groups.
- a typical example is the inorganic-organic hybrid polymer, which is known under the brand ORMOCER® of the Fraunhofer Institute for Silicate Research.
- WO 00/37 374 shows an example This approach is not mechanically very stable and is also limited by the organic components in the maximum operating temperature.
- Hydrophilic, photocatalytic layers are e.g. offered by Pilkington ("Aktiv Glas®") as easy-to-clean facade glasses. To achieve a cleaning effect, activation by UV light is imperative. In addition, the degradation rate is very low and not suitable for contact contamination.
- DE 100 18671 A1 discloses an object made in particular of glass or ceramic material, with a thin underlayer made of a metal compound, in particular made of inorganic or organic compounds with preferably tetravalent metals such as Si, Al, Ti, Zr, which are dispersed by spraying or Dipped or powdered, but also applied to the surface of the object with appropriate brine or gels and burned out at very high temperatures with decomposition of the organic components. After cooling, an outer hydrophobic organic layer made of siloxanes, silanes, fluorosilane polyurethane or tetrafluoropolyethylene is applied to this underlayer by known methods and dried.
- a metal compound in particular made of inorganic or organic compounds with preferably tetravalent metals such as Si, Al, Ti, Zr, which are dispersed by spraying or Dipped or powdered, but also applied to the surface of the object with appropriate brine or gels and burned out at very high temperatures with decomposition of the organic components.
- the EP document describes an object made of glass with a first, lower layer of silica (silica) and a second, outer, silane-containing hydrophobic layer. With this object, too, the pebble layer is burned out before the hydrophobic layer is applied. According to relevant experience, these known double layers are not sufficiently stable in the cleaning process. Due to the high burn-out temperatures, which lead to a glassy lower layer, the reactive groups in the lower layer react as far as possible, so that the chemical bonds with partners in the outer hydrophobic layer are extremely small.
- the invention has for its object to provide the above-mentioned object with a coating that passes the tests listed above, necessary for oven inner panes.
- This object is achieved by an object with an easily cleanable surface by means of a double coating with a hydrophobic outer layer having a component which reacts with free OH groups and an inner inorganic sol-gel layer, in which, according to the invention, the outer hydrophobic layer is coated on a moderate temperatures up to a maximum of 100 ° C only dried, very reactive inner sol-gel layer and firmly anchored to it by condensation reactions, and only the double-layer system on the surface of the object is baked at temperatures above 50 ° C.
- the task is accomplished by a method for producing an object with an easily cleanable surface by means of a double coating, with the steps:
- the inventive two-layer process makes it possible to produce articles with a visually unobtrusive, mechanically stable and easily cleanable protective layer.
- the lower layer the inner sol-gel layer
- the reactive groups i.e. receive the OH groups of the sol-gel layer and can form a chemical bond with molecules of the hydrophobic top layer, in particular by a condensation reaction.
- Essential for the invention is therefore the still very reactive lower sol-gel layer, the inorganic sol-gel network, which firmly anchors the second layer through a condensation reaction.
- This second layer is highly hydrophobic and therefore dirt-repellent.
- the sol-gel method is known to be a method with which mechanically stable metal oxide layers can be produced.
- a reaction of metal-organic starting materials in the dissolved state is used for the formation of the layers.
- a controlled hydrolysis and condensation reaction of the organometallic starting materials builds a typical metal oxide network structure, ie a structure in which the metal atoms are connected to one another by oxygen atoms, along with the elimination of reaction products such as alcohol and water.
- the hydrolysis reaction can be accelerated by adding catalysts.
- the lower layer therefore presents itself as a gel made of organometallic materials, in the case of the invention the preferred metals being Ti, Si, Zr, Al, Sn.
- It typically has a thickness of 10 nm to 1 ⁇ m and is applied to the surface of the object to be coated, preferably a glass substrate, using conventional methods, preferably spraying or dipping.
- spraying or dipping all methods known to the person skilled in the art can be used, e.g. also centrifugal process or steam separation process (VD, preferably CVD process).
- the surface of the object is activated before the coating with the sol-gel layer.
- activation methods are diverse and known to the person skilled in the art and include oxidation and plasma treatments or also treatment with acid and / or alkalis.
- adhesion promoter layers made of gas or liquid phase at these points before coating the object according to the invention.
- Adhesion promoter layers of this type are diverse and known to the person skilled in the art, and are easy to determine for the respective substrate material.
- a common adhesion promoter are silanes and silanols, which have reactive groups.
- it is expedient to roughen the substrate surface beforehand for example mechanically by sandblasting or chemically, for example by etching.
- Other physical methods such as corona discharge, flame treatment, UV treatment, can also be used, as can combinations of the aforementioned measures.
- a hydrophobic layer preferably a perfluorinated silane with a
- the second layer preferably contains fluoroalkyl silanes as hydrophobic components.
- Preferred silanes in the process according to the invention have the general formula
- n and m independently of one another are an integer from 0 to 20 and together give a maximum of 30 and R is a straight-chain, branched, saturated or unsaturated (optionally containing heteroatoms) Ci - to Cs-alkyl radical.
- Preferred alkyl radicals are methyl, ethyl and propyl radicals, as well as their amino derivatives.
- silanes which have heteroatoms or heteroatoms comprising functional groups which increase or mediate the water solubility of the silane.
- the sol-gel layer Before the spraying of the hydrophobic solution, the sol-gel layer has to be solidified to such an extent that there are no flow disturbances, such as contraction of the coating.
- the double-layer system is then baked at 50 ° to 450 ° C., preferably 250 ° C. to 380 ° C., for 2 minutes to 2 hours.
- the advantage of the method according to the invention is also a significant reduction in process times.
- the course and drying time of the sol-gel layer can be controlled in such a way that both layers can be applied in one spray pass with two spray heads.
- a mixed oxide underlayer is produced in such a way that a concentrate of titanium in a weight ratio of 1: 2 is added to the concentrate from Example 1a.
- the titanium concentrate is made from TiCl and ethanol by making a 128 g / L solution.
- solutions which are processed by spraying 8 g of the SiO 2 concentrate and 4 g of the titanium concentrate are mixed with 320 g of alcohol.
- a hydrophobic layer is prepared in such a way that a hydrophobic silane (e.g. Degussa, F8261) and a catalyst (acetic acid) are mixed in a weight ratio of 1:70 in acetone. This solution is then applied to a lower layer of Examples 1a and 1b.
- a hydrophobic silane e.g. Degussa, F8261
- a catalyst acetic acid
- a further hydrophobic layer is produced in such a way that equal amounts of silica ester and alcoholic solvent are briefly stirred together. Then 5% by weight of hydrophobic silane (e.g. Degussa, F8800) are mixed with the solution. 22% by weight of a mixture of water and a little catalyst (hydrochloric acid) are then slowly stirred in. The resulting concentrate then rests for 4 hours.
- a spray solution is prepared by mixing the concentrate and acetone in a 1:20 ratio by weight. This solution is then applied to an intermediate layer in Examples 1.
- hydrophobic layer system is obtained by applying a commercially available, hydrophobic solution which reacts with free OH groups (for example NanoTop®, from Flexotec, or Easy-to-Clean products from Nano-X) to one of the Lower layers Example 1 applied and applied according to the method described in Example 4 on a glass substrate.
- a commercially available, hydrophobic solution which reacts with free OH groups (for example NanoTop®, from Flexotec, or Easy-to-Clean products from Nano-X) to one of the Lower layers Example 1 applied and applied according to the method described in Example 4 on a glass substrate.
- the lower layer of Examples 1 is applied to heat-reflecting substrate glass using a conventional spraying method.
- a micro spray nozzle (from Krautzberger) is used to ensure the best possible atomization.
- the underlayer dries at room temperature.
- the hydrophobic layer (Examples 2) is applied to the dried underlayer with a micro-spray nozzle.
- the entire system is then baked at 300 ° C./20 min in such a way that the organic constituents are not decomposed, but a very good (condensation) reaction between and in the layers and the substrate is ensured.
- Example 2 As in Example 1, an SiO 2 layer was applied by spraying to two identical substrates. One sample was heated in an oven at 500 ° C for 30 minutes while the second sample was kept at room temperature under ambient ambient conditions.
- both substrates were coated with a fluorosilane by spraying, as in Example 2a, and then heat-treated at 300 ° C. for 20 minutes. Both samples were then tested by mechanically rubbing the coated surface with a wet felt pad under a 1 kg load. After a predetermined number of rubbing cycles, the contact angle of water on the rubbed surface was measured. As can be seen from the table below, the sample according to the prior art with the burned-out SiO 2 underlayer shows a rapid decrease in the contact angle with the number of friction cycles compared to the second sample coated according to the invention with an unburned SiO 2 underlayer.
- the durability of the layers is therefore strongly dependent on the temperature treatment of the lower layer.
- the layer according to the invention shows clear advantages.
- Example 6 In order to investigate the optimal lying time between the application of the hydrophobic outer layer to the unburned underlayer, samples according to Example 2a were produced with different lying times. The laydown times were 5 minutes to 1 week under normal laboratory ambient conditions. Differences in the abrasion resistance of the double layer, carried out with simplified oven cleaning tests, could practically not be determined. With regard to the short process times to be sought because of the economy, the lay time should generally be kept relatively short.
- the lay time should not exceed a certain period of time for other reasons.
- the aforementioned comparison samples (with different lay times) were mechanically rubbed with a wet felt pad, as in Example 5.
- the table below shows the contact angle before and after 500 rubbing cycles of three samples with lay times of 0.5, 6 or 24 hours before the hydrophobic layer was applied.
- the contact angle of the sample practically did not change with the lying time of 0.5 h; he stays high.
- the contact angle drops dramatically for samples with a lay time of longer than 0.5 hours from. Therefore short lay times are preferred, which should not exceed 6 hours.
- the objects which are provided with the double layer according to the invention can consist of ceramic material, such as tiles, sanitary ceramic products, or can be enamels, e.g. Oven muffles, metals such as Precious metals or plastics.
- Objects made of glass or glass ceramics represent a preferred application, such as, for example, oven inner panes or transparent fireplace doors, which are each exposed to high temperatures and / or heavy soiling and must be cleaned continuously.
