Abstract
Description
Beschreibungdescription
Die vorliegende Erfindung betrifft ein heizbaren Spiegel mit korrosionsgeschützter Rückseite.The present invention relates to a heated mirror with corrosion-proof Back.
Es sind Spiegel bekannt, auch heizbare Spiegel, deren rückwärtige Fläche durch Lacküberzüge oder aufgeklebte Folien gegen Korrosion geschützt sind. Bei den heizbaren Spiegeln dieser Art erfolgt die Beheizung mittels eines Heizleiters, <It') entweder auf den @@@cküberzug oder in die Folien einge1eL i>L. Lin Spiegel mit auf(eklebter Folie, die einen eingelegten Heizleiter enthält, ist aus der DE-OS 22 27 712 bekannt.There are mirrors known, including heated mirrors, their rear Surface are protected against corrosion by varnish coatings or glued-on foils. The heated mirrors of this type are heated by means of a heating conductor, <It ') either on the cover or in the foil. Lin mirror with on (e-glued film, which contains an inserted heating conductor, is from DE-OS 22 27 712 known.
Solche Spiegel haben den Nachteil, daß ihre Lebensdauer wegen Korrosion des Heizleiters, Ablösen des Heizleiters von der Unterlage oder Ablösen der Unterlage von der Spiegelrückseite begrenzt ist.Such mirrors have the disadvantage that their service life is due to corrosion the heatsealing band, detachment of the heatsealing band from the base or detachment of the base is limited by the back of the mirror.
Ziel der vorliegenden Erfindung ist deshalb ein Spiegel, dessen Rückseite weit besser als herkömmliche Spiegel gegen Korrosion geschützt ist. Dieses Ziel wird mit einem Spiegel und mit einem Verfahren gemäß den Patentansprüchen erreicht.The aim of the present invention is therefore a mirror, the back of which is much better protected against corrosion than conventional mirrors. This goal is achieved with a mirror and with a method according to the claims.
Der erfindungsgemäße Spiegel weist auf seiner Rückseite einen Heizleiter und auf diesem Heizleiter eine Emaille-Schicht auf.The mirror according to the invention has a heating conductor on its rear side and an enamel layer on this heating conductor.
Die Erfindung ist anwendbar auf Hinter- und Vorderfläcllenspiegel, wie z.B. Chrom-, Silber- oder Interferenzspiegel.The invention is applicable to rear and front surface mirrors, such as chrome, silver or interference mirrors.
Der Heizleiter und die Emaille-Schicht können entweder direkt auf die Rückseite des Spiegels oder auf ein Substrat aufgetragen sein, welches vorzugsweise aus einer Dünnglasscheibe besteht. Dieses Substrat wird mit dem Heizleiter und der Emaille zu einem Verbundkörper verbunden, der auf geeignete Weise, z.B. mittels Kunstharz, Klebelack oder Klebeband mit den Spiegel verbunden wird.The heating conductor and the enamel layer can either be directly on the back of the mirror or applied to a substrate, which is preferably consists of a thin glass pane. This substrate is with the heating conductor and the Enamel joined to form a composite body that is suitable for Way, e.g. connected to the mirror using synthetic resin, adhesive varnish or adhesive tape.
Der Heizleiter, der im allgemeinen aus Leitsilber besteht, wird zweckmäßigerweise im Siebdruckverfahren aufgetragen. Die Emaille wird nach dem Heizleiter, beispielsweise in einem Siebdruck-, Spritz- oder Gießverfahren aufgetragen, getrockent und in einem Tempervorgang eingebrannt.The heating conductor, which generally consists of conductive silver, is expedient applied by screen printing. The enamel is after the heating conductor, for example Applied in a screen printing, spraying or casting process, dried and in one Baked in the tempering process.
Es werden vorzugsweise Emailles verwendet, die bei einer Temperatur von etwa 4260C eingebrannt werden. Sie wird in einer Dicke von beispielsweise 120 g/m² (berechnet als nasse Paste) aufgetragen. Nach dem Einbrennen hat die Emaille-Schicht dann eine Dicke etwa 10 - 20 .There are preferably used enamels that are at a temperature can be baked in at around 4260C. It will be 120 in thickness, for example g / m² (calculated as wet paste). After baking, the enamel layer has then a thickness about 10-20.
Die Erfindung wird in der Zeichnung an drei Ausführungsbeispielen erläutert. Figur 1 zeigt schematisch einen Schnitt durch einen Vorderflächenspiegel, auf dessen Rückseite der erfindungsgemäß geschützte Heizleiter aufgebracht ist.The invention is illustrated in the drawing using three exemplary embodiments explained. Figure 1 shows schematically a section through a front surface mirror, on the back of which the heating conductor protected according to the invention is applied.
Figur 2 zeigt einen solchen Schnitt durch den aus Substrat, Heizleiter und Emaille bestehenden Verbundkörper und Figur 3 einen entsprechenden Schnitt durch einen Spiegel mit auf die Rückseite aufgebrachtem Verbundkörper.Figure 2 shows such a section through the substrate, heating conductor and enamel existing composite body and Figure 3 shows a corresponding section through a mirror with a composite body applied to the back.
Auf den Träger 1 ist eine Reflexionsschicht 2. aufgebracht. Bei dem Vorderflächenspiegel (Fig. 1) ist auf der Rückseite des Trägers 1 ein Heizleiter 4 und auf diesen eine Emaille-Schicht 3 aufgebracht, die beide gemeinsam eingebrannt sind.A reflective layer 2 is applied to the carrier 1. In which Front surface mirror (Fig. 1) is on the back of the carrier 1, a heating conductor 4 and applied to this an enamel layer 3, both of which are burned in together are.
Auf das Substrat 5 ist ein Heizleiter 4 und auf diesem eine Emailleschicht 3 aufgetragen. Der daraus gebildete Verbundkörper 6 wird auf die Rückseite des aus dem Träger 1 und der Reflexionsschicht 2 bestehenden Spiegels aufgebracht.On the substrate 5 is a heating conductor 4 and on this is an enamel layer 3 applied. The composite body 6 formed therefrom is on the back of the applied to the carrier 1 and the reflective layer 2 existing mirror.
