Description
Die Erfindung betrifft Glasgeschirr aus gepreßtem, gegossenem oder geblasenem Glas, Geschirr aus temperaturbeständigem Porzellan und Geschirr aus unglasierter oder teilweise glasierter Keramik, insbeson dere Schüssel, Schalen, Behälter, Töpfe, Pfannen und Auflaufformen zum Kochen, Braten, Schmoren, Dünsten und Garen in Koch- und Backherden sowie in Mikrowellen, dessen Oberfläche teilweise oder vollständig mit einer weitgehend kratzfesten Antihaftschicht aus Poly tetraflouräthylen (Teflon) beschichtet ist, die zur besseren Haftung auf einer farbigen Glas-/Keramikgrundierung aufgetragen und bei 380°C-420°C eingebrannt wird.The invention relates to glassware made of pressed, cast or blown glass, tableware made of temperature - resistant porcelain and Utensils made of unglazed or partially glazed ceramic, in particular bowls, bowls, containers, pots, pans and casserole dishes for cooking, roasting, braising, steaming and cooking in cooking and Ovens and in microwaves, the surface of which is partly or completely with a largely scratch-resistant non-stick layer made of poly tetrafluoroethylene (Teflon) is coated, which improves adhesion applied a colored glass / ceramic primer and at 380 ° C-420 ° C is baked.
Antihaftbeschichtungen von Koch- und Bratgeräten aus Metallen sind seit vielen Jahren gut bekannt. Die guten Eigenschaften, die mit sol chen Beschichtungen erreicht werden, haben zu einer weiten Verbrei tung derartiger Geschirre aber auch zu einer ständigen Verbesserung der Beschichtungstechnologien geführt.Non-stick coatings of cooking and roasting utensils are made of metal well known for many years. The good properties that come with sol Chen coatings are achieved have a wide range of such harnesses also leads to constant improvement of coating technologies.
Der gegenwärtige Stand der Technik ist dadurch gekennzeichnet, daß neben den üblichen Materialien für die Herstellung von antihaftbe schichteten Brat- und Kochgeschirren aus Aluminium und Alumini umguß auch Verfahren zur Beschichtung von anderen metallischen Materialien entwickelt wurden. In der Schrift DE 28 43 681 wird ein Verfahren zur Beschichtung von Stahlgeschirren beschrieben, bei dem die Haftfähigkeit der Antihaftschicht auf Edelstahl durch den Einsatz einer speziellen Trägerschicht erreicht wird. In der Schrift G 93 19 104.9 werden antihaftbeschichtete Kochgeschirre beschrieben, herge stellt aus einem Verbundwerkstoff aus aluminimbeschichtetem Eisen blech, die die wärmetechnischen Vorteile des Eisens und die Kor rosionsbeständigkeit sowie die guten Haftungseigenschaften des Alu miniums gegenüber Teflon vereinen.The current state of the art is characterized in that in addition to the usual materials for the production of non-stick layered roasting and cooking utensils made of aluminum and aluminum also casting process for coating other metallic Materials were developed. In the document DE 28 43 681 a Process for coating steel tableware described, in which the adhesion of the non-stick layer to stainless steel through the use a special carrier layer is achieved. In the publication G 93 19 104.9 non-stick coated cookware are described, herge is made of a composite material made of aluminim-coated iron sheet metal, the thermal advantages of iron and the cor corrosion resistance and the good adhesion properties of the aluminum unite miniums compared to Teflon.
Die Beschichtung von hochtemperaturfestem Glasgeschirr mit einem temperaturbeständigem Kunststoff wird in der Schrift P 16 79 115.4 aus dem Jahre 1966 beschrieben. Da die Haftungseigenschaften von Teflon auf Glas sehr schlecht sind und die Antihaftschicht beim Ge brauch sehr leicht abgekratzt und zerstört wird, wird vorgeschlagen die innere Oberfläche der Glasgefäße bei der Herstellung zu strukturieren, so daß beim Kratzen die Antihaftschicht nur an den Spitzen der Struk turelemente beschädigt werden kann. Derartig Glasgeschirre verlieren aber durch die Beschichtung nicht nur ihre Transparenz, sondern durch die Strukturierung auch ihre glatte innere Oberfläche und werden beim Gebrauch sehr schnell unansehnlich, da die Antihaftschicht an den Spitzen der Elemente noch stärker beansprucht und schnell zerstört wird. Damit weisen diese Glasgeschirre gegenüber metallischen Koch geschirren keinerlei Vorteile mehr auf, die ihre schlechteren Wärmeei genschaften aufwiegen. Sicher ein Grund, daß sich derartig antihaftbe schichtete Glasgeschirre nicht bewährt haben.The coating of high temperature resistant glassware with a temperature-resistant plastic is described in P 16 79 115.4 from 1966. Because the adhesive properties of Teflon on glass are very bad and the non-stick layer in Ge need to be scraped off and destroyed very easily, it is proposed structure the inner surface of the glass vessels during manufacture, so that when scratching the non-stick layer only at the tips of the structure door elements can be damaged. Lose such glassware but not only through the coating, but also through its transparency the structuring also their smooth inner surface and are used in the Use very quickly unsightly, because the non-stick layer on the Peaks of the elements are even more stressed and quickly destroyed becomes. These glassware thus point towards metallic cookware harness no more benefits that their worse heat egg outweigh properties. Certainly a reason that such non-stick layered glassware have not proven.
In der Schrift P 26 21 255.5 wird die Beschichtung der Innenfläche von Backformen aus Keramik mit Antihaftmitteln beschrieben. Der Vorteil derartig beschichteter Backformen besteht vor allem in der Verbindung der guten Backeigenschaften von Keramikformen und den Antihafteigenschaften der Beschichtung, die ein Festkleben der Back ware an der Innenfläche der Formen verhindert. Bei einem Auftrag der Antihaftschicht auf eine unglasierte poröse Innenfläche entsteht eine feste weitgehend kratzfeste Beschichtung. Weniger kratzfest ist aber eine Beschichtung auf einer glasierten, glatten Oberfläche, da hier die schlechten Antihafteigenschaften von Polytetraflouräthylen auf Glas zum Tragen kommen.P 26 21 255.5 describes the coating of the inner surface described of ceramic baking molds with non-stick agents. Of the The advantage of baking tins coated in this way is particularly that Combining the good baking properties of ceramic molds and Non-stick properties of the coating that prevent the back from sticking would be prevented on the inner surface of the molds. With an order from A non-stick layer on an unglazed porous inner surface is created solid, largely scratch-resistant coating. But it is less scratch-resistant a coating on a glazed, smooth surface, because here the poor non-stick properties of polytetrafluoroethylene on glass come to fruition.
Der Erfindung liegt die Aufgabe zugrunde, Glas- und Porzellange schirre mit glatten inneren Oberflächen und Keramikgeschirre mit teilweise oder ganz glasierten Oberflächen mit einem Antihaftbelag aus hochtemperaturfestem Kunststoff zu beschichten, der bezüglich der Eigenschaften und Haltbarkeit mit denen von beschichteten Metallge schirren vergleichbar ist und bei dem auch nach längerem Gebrauch die Geschirre ihre Antihafteigenschaften und ihr dekoratives Aussehen behalten.The invention has for its object glass and porcelain harness with smooth inner surfaces and ceramic dishes partially or completely glazed surfaces with a non-stick coating to coat high-temperature-resistant plastic with respect to the Properties and durability with those of coated metal harnessing is comparable and even after prolonged use the harnesses their non-stick properties and their decorative appearance to keep.
Dies wird erfindungsmäßig dadurch gelöst, daß die Antihaftschicht nicht direkt auf die ganz fein mechanisch aufgeraute Innenfläche der Glas-, Porzellan- oder Keramikgeschirre aufgebracht wird, sondern auf eine spezielle Glasgrundierung, die auf Glas, Porzellan oder der Keramikglasur weit bessere Haftungseigenschaften als Teflon besitzt und die während des Sinterprozesses beim Einbrennen der Antihaft schicht eine feste dauerhafte Verbindung mit dem Polytetraflouräthylen bildet. In der Fig. 1 ist der Aufbau eines derartigen Beschichtungs belages am Beispiel einer Auflaufform dargestellt.This is solved according to the invention in that the non-stick layer is not applied directly to the very finely mechanically roughened inner surface of the glass, porcelain or ceramic tableware, but to a special glass primer which has far better adhesion properties than glass, porcelain or ceramic glaze and which forms a firm, permanent connection with the polytetrafluoroethylene during the sintering process when the non-stick layer is baked on. In Fig. 1, the structure of such a coating is shown using the example of a baking dish.
Die Verwendung der Glasgrundierung bietet außerdem den Vorteil, daß diese nach dem Trocknen auf der Glas-, Porzellan- oder Keramik oberfläche eine harte, kratzfeste und glatte Oberfläche bildet. Durch die Möglichkeit der farblichen Gestaltung der Grundierung erhalten Glasgeschirre, die nur innen beschichtet sind, ein dauerhaftes deko ratives Aussehen.The use of the glass primer also offers the advantage that after drying on the glass, porcelain or ceramic surface forms a hard, scratch-resistant and smooth surface. By get the opportunity to color the primer Glass dishes that are only coated on the inside, a permanent decoration ratative appearance.
Die Grundierung wird auf die glatte oder teilweise mechanisch aufge raute Innenfläche der Geschirre aufgetragen und bei etwa 100°C getrocknet. Durch ihre auf Glas und Porzellan abgestimmten Haftungseigenschaften entsteht ein fester, geschlossener, glatter Untergrund. The primer is applied mechanically to the smooth or partially rough inner surface of the dishes and applied at about 100 ° C dried. Through their matched to glass and porcelain Adhesion properties create a firm, closed, smoother Underground.
Nach dem Auftragen der Antihaftbeschichtung auf die Grundierung wird das Geschirr bei 380°C-420°C etwa 10-15 Minuten getem pert, so daß durch den Sinterprozeß eine feste Verbindung zwischen der Antihaftschicht und der Grundierung entsteht. Dieser Belag aus einer einfachen oder mehrfachen Beschichtung mit Teflon und der Grundierung bildet auf der harten Oberfläche der Glas-, Porzellan- oder Keramikgeschirre eine festere Schicht als ein vergleichbarer Belag auf einer Aluminiumunterlage.After applying the non-stick coating on the primer the dishes are heated at 380 ° C-420 ° C for about 10-15 minutes pert, so that through the sintering process a firm connection between the non-stick layer and the primer are created. This topping a single or multiple coating with Teflon and the Primer forms on the hard surface of the glass, porcelain or Ceramic dishes have a firmer layer than a comparable surface on an aluminum base.
Derartig beschichtete Glasgeschirre besitzen somit auf der Außenseite die pflegeleichten Eigenschaften von Glas, sind durch die nach außen durchscheinende Grundierung dauerhaft dekorativ zu gestaltet und haben auf der Innenseite eine äußerst haltbare, weitgehend kratzfeste und glatte Antihaftbeschichtung.Glass dishes coated in this way thus have on the outside The easy-care properties of glass are due to the outside translucent primer designed to be permanently decorative and have an extremely durable, largely scratch-resistant on the inside and smooth non-stick coating.
Neben den hochtemperaturfesten Geschirren aus Preßglas lassen sich auch geblasenen Gebrauchsgegenstände aus Glas, wie Schüsseln und Behälter derartig beschichten. Durch eine nur teilweise Beschichtung der Innenfläche, z. B. bei Back- oder Auflaufformen, bleibt zudem die dem Glas eigene Transparenz teilweise erhalten.In addition to the high-temperature-resistant tableware made of pressed glass, also blown glass utensils, such as bowls and Coat containers like this. Due to only a partial coating the inner surface, e.g. B. in baking or casserole dishes, also remains some of the glass's own transparency.
Porzellan- und Keramikgeschirre lassen sich in dieser Art sowohl innen als auch außen beschichten. Durch eine komplette Beschichtung er halten diese Geschirre weit bessere Gebrauchseigenschaften. Keramik geschirr wird durch die Beschichtung komplett versiegelt und nimmt beim Spülen kein Wasser mehr auf. Dadurch läßt es sich ebenso wie Porzellangeschirr zum Kochen in der Mikrowelle verwenden.Porcelain and ceramic tableware can be used on the inside in this way as well as coat outside. Through a complete coating keep these harnesses far better in use. Ceramics dishes are completely sealed by the coating and take no more water when rinsing. This makes it just as easy Use porcelain dishes for cooking in the microwave.
Durch die beschriebene Beschichtungsverfahren entstehen somit Ge schirre mit neuen verbesserten Gebrauchseigenschaften, die sich viel fältig einsetzen lassen. In der Fig. 2 sind einige Formen von Geschirr und Gebrauchsgegenstände aus Glas, Porzellan oder Keramik ange geben, die sich vorzugsweise für eine Antihaftbeschichtung auf einer Glas-/Keramikgrundierung eignen.The coating method described thus creates harnesses with new improved performance properties that can be used in a variety of ways. In Fig. 2 some forms of dishes and utensils made of glass, porcelain or ceramic are given, which are preferably suitable for a non-stick coating on a glass / ceramic primer.
