REDUCING THE CORROSION OF SILVER WIRES ON A GLASS SUBSTRATE

Abstract

A vehicle pane includes a glass substrate with elemental silver applied thereon discontinuously, as one or a plurality of lines, wherein the elemental silver has a coating that contains a thiol and/or a silicone resin and/or a silicate.

Claims

1. A vehicle pane comprising a glass sub strate with elemental silver applied thereon discontinuously as one or a plurality of lines, wherein the elemental silver has a coating that contains a thiol and/or a silicone resin and/or a silicate.

2. The vehicle pane according to claim 1, having the form of a rear window.

3. The vehicle pane according to claim 1, wherein the silver is applied as a plurality of lines that are connected to one another at their ends.

4. The vehicle pane according to claim 3, wherein the plurality of lines form part of a heating system.

5. The vehicle pane according to claim 1, wherein the elemental silver applied as one or a plurality of lines forms one or a plurality of conductor tracks of at least one sensor or at least one antenna.

6. The vehicle pane according to claim 1, wherein the coating contains a thiol.

7. The vehicle pane according to claim 1, wherein the coatingcontains a silicone resin.

8. The vehicle pane according to claim 7, wherein the coating additionally contains one or more of a zinc salt, a zinc complex, a zirconium salt, and a zirconium complex.

9. The vehicle pane according to claim 1, wherein the coating contains silicate.

10. The vehicle pane according to claim 1, wherein the glass substrate is a heat-treated glass.

11. The vehicle pane according to claim 1, wherein the coating is applied only on the elemental silver.

12. The vehicle pane according to claim 1, wherein the coating is applied substantially over an entire surface of the vehicle pane.

13. A method for producing a vehicle pane according to claim 1, comprising: providing a glass substrate that has a system applied thereon formed from one or a plurality of wires that contain elemental silver, applying a coating that comprises a thiol and/or a silicone resin and/or silicate on the one or the plurality of wires, and optionally, curing the coating.

14. A method comprising manufacturing a vehicle pane that includes a system formed from one or a plurality of wires comprising elemental silver, the manufacturing comprising applying a composition on the wires as a coating, the composition comprising a thiol and/or a silicone resin.

15. A method comprising manufacturing a vehicle pane that includes a system formed from one or a plurality of wires comprising elemental silver, wherein silicate that is applied on the wires as a coating is produced from a composition by combustion, the composition comprising a silicate precursor.

16. The vehicle pane according to claim 6, wherein the thiol is an aliphatic C12 to C20 thiol.

17. The vehicle pane according to claim 7, wherein the silicone resin is an alkylated silicone resin.

18. The vehicle pane according to claim 9, wherein the coating is made of silicate.

19. The vehicle pane according to claim 10, wherein the glass substrate is a tempered glass.

20. The method according to claim 14, wherein the coating is a protective coating against discoloration.

Description

[0061] The invention is explained in detail with reference to figures and exemplary embodiments. The drawings are schematic representations and not to scale. The figures in no way restrict the invention. They depict:

[0062] FIG. 1 a schematic viewof a vehicle pane implemented as a rear windowcomprising a glass substratel with a plurality of wires made of elemental silver2 applied thereon, which are connected to one another at their ends via common bus bars 3. According to the invention, at least the wires are provided with a coating.

[0063] FIG. 2 a schematic view of a cross-section of a wire made of elemental silver2 with a surface coating 4 made of thiols on a glass substrate 1. The wire is, for example, a heating wire,

[0064] FIG. 3 a schematic view of a cross-section of a wire made of elemental silver2 with a surface coating 4 made of silicone on a glass substrate 1, wherein the entire surface of the glass substrate 1 is covered with the silicone. The wire is, for example, a heating wire.

[0065] Overall, the implementation of the invention is not limited to the aspects highlighted above and the examples described above, but, rather, is also possible in a large number of variations that are within the scope of the appended claims.
