Definitions
- Laminated glazing is glazing in which two sheets of glass are adhesively bonded by means of a lamination insert. The latter makes it possible in particular to retain shards of glass in the event of breakage, but also provides other functionalities, in particular in terms of burglary resistance or improved acoustic properties.
- These glazings often include coatings of various types, intended to impart different properties.
- Layers of enamel are often deposited on part of the glazing, usually in the form of a peripheral strip intended to conceal and protect against ultraviolet radiation the polymeric seals used to fix and position the glazing on the body bay. Enameled areas also conceal the attachment areas for the interior mirror and various connectors and sensors.
- these enamel layers are generally arranged on face 2, the faces being traditionally numbered starting from the face intended to be positioned outside the vehicle. Face 2 is therefore a face in contact with the lamination insert.
- the aesthetic appearance of the enamel layer seen from the outside of the vehicle is of particular importance for automakers.
- Enamel is generally obtained by firing above 500°C a composition comprising a glass frit and pigments.
- a glass frit consists of fine particles of a low melting point glass, which under the effect of a baking heat treatment softens and adheres to the glass sheet.
- a mineral layer is thus formed, generally opaque, with high chemical and mechanical resistance, adhering perfectly to the glass while maintaining the pigment particles.
- the firing step is generally carried out simultaneously with the bending of the glass sheet.
- the two sheets of glass of the glazing are often bent together, the sheet of glass intended to be positioned inside the vehicle generally being arranged above the other sheet of glass, who wears the enamel. In other processes, each sheet of glass is bent separately.
- enamels containing bismuth that is to say obtained from glass frits containing bismuth oxide, are usually used.
- Coatings generally in the form of stacks of thin layers, can also be present on one of the glass sheets of the laminated glazing. They may in particular be electrically conductive layers, which may provide two types of functionality. The electrically conductive layers can on the one hand, when current leads are provided, dissipate heat by Joule effect. These are then heating layers, useful for example for defrosting or demisting.
- These layers present on the other hand, by their reflection of the radiation infrared, solar control or low emissivity properties. The layers are then appreciated for improving thermal comfort or for the energy savings they provide, by reducing consumption for heating or air conditioning.
- These stacks of layers are generally arranged on face 3 of the laminated glazing, therefore also in contact with the lamination insert. It may however be interesting, in certain cases which will be detailed later, to arrange the enamel layer and the stack of thin layers on the same glass sheet, and therefore on the same face of the glass sheet in question. so that these coatings are protected inside the laminated glazing.
- the subject of the invention is a process for obtaining a curved laminated glazing, in particular for the windshield or roof of a motor vehicle, comprising the following successive steps: a. providing a first glass sheet, coated on at least part of one of its faces with a stack of thin layers, b.
- the invention also relates to a curved laminated glazing, in particular for the windshield or roof of a motor vehicle, obtained or capable of being obtained by this process.
