Definitions
- the present invention relates to a substrate with an alkali-resistant protective layer based on titanium oxide / cerium oxide, the substrate or at least one surface layer of the substrate consisting of an inorganic non-metallic matrix material.
- Substrates or coatings made of glass, glass ceramics and ceramics are often attacked by bases.
- high-energy radiation such as UV radiation, high temperatures or a combination of these factors can also cause damage.
- chemical and pharmaceutical industry e.g. The dissolution and aging of glass in production machines, laboratory equipment and also in windows is a major problem.
- the aging or dissolution process of the glass network can, e.g. can be represented by the following equation:
- Some high-temperature resistant materials such as Ti-sputtered BN layers are extremely durable. However, the production of these layers is technically complex and therefore very expensive. In addition, they are not transparent and cannot be applied to geometrically sophisticated glasses.
- JP-A-2002036427, EP-A-1050603 and EP-A-696624 describe coatings made of metal oxides such as Zr0 2 , Al 2 0 3 , Y 2 0 3 and La 2 0 3 , which are also Ce0 2 - and / or Ti0 2 additives can contain, described as protection for metals and metal alloys against corrosion.
- metal oxides such as Zr0 2 , Al 2 0 3 , Y 2 0 3 and La 2 0 3 , which are also Ce0 2 - and / or Ti0 2 additives can contain, described as protection for metals and metal alloys against corrosion.
- the object of the present invention was to protect inorganic non-metallic materials from attack by alkaline media.
- the protective layer should also have high heat resistance, be stable against UV light and not impair the optical effects of the material.
- the manufacture should be simple and inexpensive.
- a protective layer based on titanium oxide / cerium oxide which is obtainable by applying a coating composition comprising titanium oxide and cerium oxide precursors to a substrate with a surface made of an inorganic non-metallic matrix material and compacting the coating composition at a temperature of at least 500 ° C. Astonishingly, when compaction takes place at a temperature of at least 500 ° C., there is a layer whose permeability to alkaline media is severely restricted, so that alkali and OH " ions can no longer attack the underlying substrate or its coating
- the barrier or protective layer used according to the invention provides excellent protection for inorganic non-metallic materials, in particular glass, glass ceramic and ceramic, against attack by alkaline media.
- the alkali-resistant protective layer is also resistant to high temperatures, stable against UV radiation and transparent.
- the protective layer can be coated by conventional wet chemical coating processes, e.g. Spraying or dipping can be applied in one step. The production is therefore simple and inexpensive.
- the titanium oxide / cerium oxide layer is therefore suitable as an alkali-resistant, high-temperature-resistant, UV-stable and transparent protective layer for inorganic non-metallic materials.
- the substrate can have different geometries.
- An advantage of the invention is that even objects with more complex geometries can be coated easily.
- the substrate can also only be partially provided with the protective layer. For example, it is possible to only coat the inside of glass jars.
- Coated or uncoated substrates are suitable as substrates, part or all of the surface consisting of an inorganic non-metallic matrix material. Coated substrates can also have more than one layer. If there is a coating of an inorganic non-metallic matrix material, the substrate can be made of any other material.
- the inorganic matrix may also contain organic groups, e.g. Methyl groups.
- the inorganic non-metallic materials for the substrate itself or the coating are, for example, glass, glass ceramic or ceramic. This closes also oxide ceramics and enamel.
- Oxide ceramics are usually understood to mean ceramics that are not based on silica as the main component.
- semiconductors such as optionally doped Si or Ge, are also suitable as inorganic non-metallic matrix materials.
- Glass substrates such as e.g. B. borosilicate glass, soda-lime glass or silica glass. It can be flat glass, hollow glass such as container glass, or laboratory equipment glass.
- ceramics are ceramics based on the oxides Si0 2 , Al 2 0 3 , Zr0 2 or MgO or the corresponding mixed oxides.
- additional components can be contained in the matrix made of glass, glass ceramic or ceramic, which serve, for example, as function carriers.
- the matrix can contain, for example, pigments or metal colloids as coloring components.
- Substrates can have a functional coating, for example made of glass, glass ceramic or ceramic, which, for example, has a decorative effect or has electrical conductivity or optoelectronic effects.
- the substrates can, for example, be coated with indium tin oxide (ITO), antimony tin oxide (ATO) or fluorine-doped tin oxide (FTO) in order to achieve optoelectronic effects.
- Metals can be coated with a layer of glass or an enamel before the protective layer is applied. An example of such a Si0 2 coating of metal surfaces is described in DE-A-19714949.
- the inorganic non-metallic materials for the substrate itself or the coating can optionally also be organically modified inorganic polycondensates (for example made from tetraalkoxysilanes and methyltrialkoxysilanes), which are usually glass-like.
- These glass-like materials are glasses that can contain organic groups in the inorganic matrix structure. It is known that organic groups such as methyl may remain in the matrix even at the high temperatures required to compact the protective layer.
- the alkali-resistant protective layer is preferably applied directly to glass, glass ceramic or ceramic substrates, to glass-coated metals or to glass substrates provided with at least one functional layer.
- a coating composition comprising titanium oxide and cerium oxide precursors is applied to the surface of the substrate.
- the coating composition is usually obtained from cerium and titanium compounds in a solvent, preferably by the so-called sol-gel process.
- At least one cerium salt and at least one hydrolyzable titanium compound are preferably converted in a solvent according to the sol-gel process into the titanium oxide and cerium oxide precursors, usually in the form of a sol.
- hydrolyzable compounds are usually hydrolyzed with water, if appropriate with acidic or basic catalysis, and, if appropriate, at least partially condensed.
- the reaction of the cerium salts with water is also regarded here as hydrolysis.
- the hydrolysis and / or condensation reactions lead to the formation of compounds or condensates with hydroxyl, oxo groups and / or oxo bridges, which serve as titanium oxide and cerium oxide precursors, which precursors can also consist of condensates which contain both elements (Ce, Ti ) contain.
- Stoichiometric amounts of water but also smaller or larger amounts can be used.
- the sol that forms can be adjusted by suitable parameters, e.g.
- Cerium (III) salts are preferably used as cerium compounds.
- Cerium (III) salts which are found at room temperature in dissolving an alcohol are, for example, the nitrate and the chloride, the nitrate being particularly preferred.
- the titanium compound is in particular a hydrolyzable compound of the formula TiX 4 , where the hydrolyzable groups X are, for example, hydrogen, halogen (F, Cl, Br or I, in particular Cl and Br), alkoxy (preferably C.sub.14-alkoxy, in particular C. ⁇ alkoxy, such as methoxy, ethoxy, n-propoxy, i- propoxy, butoxy, i-butoxy, sec-butoxy and tert-butoxy), aryloxy (preferably C6. 10, aryloxy, such as phenoxy), acyloxy (preferably C ⁇ acyloxy, such as acetoxy or propionyloxy) or alkylcarbonyl (preferably C 2.
- the hydrolyzable groups X are, for example, hydrogen, halogen (F, Cl, Br or I, in particular Cl and Br), alkoxy (preferably C.sub.14-alkoxy, in particular C. ⁇ alkoxy, such as methoxy, ethoxy,
- alkylcarbonyl such as acetyl
- Preferred hydrolyzable radicals are alkoxy groups, in particular C 1-4 alkoxy.
- Specific and preferably used titanates are Ti (OCH 3 ) 4 , Ti (OC 2 H 5 ) 4 and Ti (n- or i-OC 3 H 7 ) 4 .
- an organic solvent in which the cerium and titanium compounds used are soluble is used as the solvent.
- alcohols are used, preferably an alcohol having 1 to 4 carbon atoms, e.g. Methanol, ethanol, propanol and isopropanol, or a mixture thereof.
- the resulting solution is in the presence of water, for example under reflux, at room temperature (about 20 ° C.) or at a slightly elevated temperature for a time-dependent period, for example from 1 min to several days ( for example up to 8 days), in order to obtain the coating composition comprising the titanium oxide and cerium oxide precursors, in particular in the form of a sol.
- the treatment can, for example, take place under reflux for 1 minute to 24 hours or at 30 ° C. for 10 hours to 5 days.
- the amounts of the titanium and cerium starting compounds are preferably chosen so that the molar ratio, based on Ti: Ce, is 1: 2 to 2: 1.
- brine by dissolving cerium (III) salt eg cerium (III) nitrate hexahydrate
- cerium (III) salt eg cerium (III) nitrate hexahydrate
- a titanium tetraalkoxide in concentrations of 0.05 to 0.5 mol per liter, preferably 0.2 to 0.3 mol per liter
- heating the clear solution under reflux or at a slightly elevated temperature 25 to 40 ° C
- Prehydrolysis and / or condensation takes place, forming a sol and increasing the viscosity.
- These brines can be stored for several weeks, especially when stored at temperatures around -20 ° C.
- the coating composition may optionally contain other components, e.g. B. hydrolyzable compounds or salts of other elements for the matrix or other additives such as sintering aids.
- the hydrolyzable compounds of other elements which can optionally be incorporated into the oxide matrix are, in particular, compounds of glass- or ceramic-forming elements, for example compounds of at least one element M from the main groups IM to V and / or the subgroups II to IV of the periodic table of the elements. These can be hydrolyzable compounds of Si, Al, B, Sn, Ti, Zr, V or Zn.
- hydrolyzable compounds can also be used, such as those of elements of main groups I and II of the periodic table (for example Na, K, Ca and Mg) and subgroups V to VIII of the periodic table (for example Mn, Cr, Fe and Ni) or hydrolyzable compounds other lanthanides.
- such other components based on the solids content of the finished protective layer, make up no more than 20% by weight, preferably no more than 5% by weight and in particular no more than 2% by weight.
- the protective layer is particularly preferably formed only from the titanium oxide / cerium oxide.
- the coating composition is applied to the substrates to be coated using the usual coating methods after the viscosity has been adjusted, if appropriate, by adding or removing solvent.
- the coating can be done, for example, by spraying, dipping, brushing or spin coating.
- the substrates are generally dried at room temperature or at elevated temperature (for example up to 100 ° C.). This is followed by compaction of the applied layer at temperatures in the range from 500 ° C. to just below the softening point of the substrate or coating material. Temperatures are preferably chosen just below the softening point of the material to be coated (Tg of the glass), which of course depends on the type of substrate or coating.
- the coating composition can be compacted into crack-free, transparent and homogeneous coatings despite the possibly present organic components.
- the heat treatment for compression can e.g. in the oven, by means of IR radiation or by flaming.
- the protective layer is annealed by the heat treatment.
- a matrix of oxides or mixed oxides (double oxides) of titanium and cerium (TiOj / CeO ;,) is obtained, here referred to as titanium oxide / cerium oxide, the stoichiometry depending on the molar ratio of the starting compounds used.
- the protective layer obtained offers extremely good protection against attack by alkaline media.
- the coating was able to achieve exceptional alkali resistance. In this way, a 30% sodium hydroxide solution could be heated to 80 ° C. in the reactor coated in this way without damage to the reactor being observed.
