Definitions
- this glass is unrolled, heated in an oven and rolled down to a layer thickness of up to 5 ⁇
- plastic-glass composite systems with glass layer thicknesses are offered by about 25 ⁇ currently. Massive difficulties are the physics of the glass, namely the brittleness and the associated high fragility.
- glass foils with such small thicknesses per se are already extremely sensitive as free-standing foils, both mechanically and with respect to contamination, which can subsequently lead to irreversible defects due to sintering or rolling on. This means that the glass sheets must first be laminated to plastic films for any further handling. Because of the high risk of breakage and contamination, this process is also very critical.
- CONFIRMATION COPY is clearly below 25 ⁇ go, the process is not practicable to date. Below 5 ⁇ there are currently no Kunststofffolienverbunde.
- ultrathin glass layers on temperature-resistant substrates can also be prepared via sol-gel processes by sputtering processes by applying a sol to the substrate (for example glass, metals, ceramics) and then heating to temperatures in the range around Tg, ie via a subsequent energy-supplying, in particular thermal, process, the sol is first converted into a gel phase and then into the glass phase (see book Brinker / Scherer).
- a sol for example glass, metals, ceramics
- the sol is first converted into a gel phase and then into the glass phase (see book Brinker / Scherer).
- the synthesis of the ceramic phases usually only takes place after the shaping.
- a stable mold is produced by the various processes described in the relevant literature and then converted into the ceramic phase in a sintering process, which consists of one to several components, wherein glass phases can also occur, especially in the grain boundaries.
- the preparation of thin ceramic layers via sputtering processes on a substrate and removal of this substrate after adhering to a second substrate is described in the literature, but no such temperature-condensing or self-supporting layers are known.
- such layers are not sufficiently diffusion-tight in the case of vapor deposition or sputtering processes, since the crystallites which generally grow adjacent to one another do not form a tightly closed layer.
- the ITO layers used in architectural glazing as efficient infrared blockers can only be applied to the inside of double-glazed windows because they are not sufficiently mechanically stable or weatherproof due to their non-hermetic sealing layer.
- the latter is due to the fact that because of the non-dense packing water can enter the interface ceramic / glass, which leads to the destruction of the function of the layers.
- the composition of sputtered ceramic layers is limited to relatively simple compositions. More complex systems are practical with this method. table not feasible, especially if they are to be diffusion-tight. This also means that, with ceramic layers sputtered onto substrates, unsupported thinnest ceramic layers or foils can practically not be produced by this process.
- ultra-thin ceramic layers can only be produced by sol-gel processes by applying a sol to a temperature-resistant substrate (glass, metals, ceramics). Through a subsequent thermal process, the sol is first converted into a gel phase and then into the ceramic phase.
- a temperature-resistant substrate glass, metals, ceramics
- the sol is first converted into a gel phase and then into the ceramic phase.
- thin ceramic layers can be produced by such methods, they are generally inseparably bonded to the substrate and thus can not be produced as freestanding films.
- Another variant of the coating is the deposition of particles via electrophoresis, as described in the relevant literature.
- compositions which result in sputtered inorganic glasses such transfer methods are not described.
- only a limited number of glass-forming elements can be used via sputtering methods, since the deposition of multicomponent glasses is very critical, and in some cases not possible.
- temperatures of at least Tg are required, and these are usually in the range of 500 ° C and above.
- the object of the invention was to produce ultrathin glass / ceramic composite systems in which either stable intermediates without the complex process steps described above and / or the intermediate stage of a self-supporting film no longer are required, and in which the existing state of the art limit of 5 ⁇ can be significantly below.

- This can z. Example, be repeated several times, and it can be used for the multilayers sols of different composition.
- the ascent laminate of the coated substrate is carried on a carrier system, and removing said substrate '(A).
- this basic principle even complex components can be produced if, after drying the wet-chemically produced thin sol layer on the removable substrate, this layer system is pressed into any desired shape.
- Example of plastic films on the molded layer system can be done for example with thermoformable substrates using the form used for forming the composite layer.
- the production method does not exclude or permit the principles for a continuous production or an additional functionalization.
- the glass / ceramic composite system can be transferred to any substrates and also has sufficient flexibility to coat non-planar substrates can. Alternatively, the substrate may also be removed prior to lamination and the remaining self-supporting film applied to a carrier sheet.
- the heating process is carried out so that no residues of organic nature remain in the resulting glass, for example by means of a heating rate of 1 to 30 ° C / min, for example from 4 to 12 ° C / minute.
- the atmosphere (oxygen content) and the heating curve are adjusted so that a complete oxidation takes place.
- Various techniques can be used for heating, such as convection heating, continuous flow furnaces or stationary ovens. However, radiation curing with UV, visible light, microwaves (if no conductive substrate (A) is used) or IR can also be used.

- the thin-glass carrier system can, for example, with the Glass side or the carrier system side to the atmosphere on a substrate or component laminated or glued. With suitably adjusted adhesion can be removed in the case of a directed to the atmosphere carrier system and then, for example, only the Dünnstglas für remains on the component or substrate.

(Sheet drawings, Fig. 1). As substrates (C) z. As plastic films, textiles, wood or chemically resistant papers are used.
- the composite systems can also be produced continuously.
- the principle of continuous production is based in particular on a so-called roll-to-roll process in which a supply roll is coated with a temperature-resistant, thin, flexible substrate by means of a roll application process with a desired gel layer. After the layer has dried, it can optionally also be provided with an embossing for structuring. Optionally, the sol can also be embossed with egg texture. This is followed by compaction via energy supply, for example in an oven, via infrared radiation or via flash-light method.

- the primer solution prepared in this way is applied to a polycarbonate film in a layer thickness of 3 ⁇ m. Dried for 5 min at room temperature.
- the cured coated aluminum foils are placed with the layer side on the transparent thermoplastic polycarbonate film and sealed with a heated to 140 ° steel plate at a pressure of 0.5 bar for 10 min. After dissolution of the aluminum in an acid bath and rinsing of the resulting aluminum hydroxide thin glass or ceramic layer composites are obtained according to Example 5.
- Example 17 Production of a glass textile composite with the Na-Li-Si glass system via direct bonding.
- Example 18 Production of a Textured Glass Textile Composite with the Na-Li-Si Glass System via Direct Bonding.
- a glass film according to Example 5 of 4 cm edge length and 4 ⁇ thickness of the Na-Li-Si- G lassystems was glued to a provided with a commercial PU adhesive, textile polyester-based fabric (substrate component (C)) by pressing a soft rubber plate and 1 h allowed to cure for a long time.
- the result is a firmly adhering, transparent and -flexibles glass textile composite system with a fabric-derived surface texture.
- Example 19 Production of a Glass-Coated Molded Body
- a glass film according to Example 5 was placed on a concave circular mold and poured out with a plastic mass. The result is a thin glass-coated hemisphere without cracks in the coating.
