Definitions
- the present invention relates to Laminated assembly made to protect and/or to add functionalities to a panel, and in particular large size panels.
- Panels such as decorative signs, painted panels, pieces based on natural material,... can be damaged, scratched, peeled, attacked due to
- Such treatments can be a protective paint, a stain, a lacquer and/or a chemical surface treatment.
- Another way of protection is to add a layer on top of the panel such as plastic layer or an alumino-silicate glass to be as discrete as possible and then as thin as possible.
- U.S. patent application Ser. No. 2009/0202808 discloses a alumino- silicate glass article used as a cover glass to protect an electronic devices such as such as cell phones, hand held games, MP3 players, watches, laptop computers, mobile GPS.
- Alumino-silicate needs specific furnaces or specific processes. This kind of glass articles is expensive to produce and can be used only for small articles due to the price and difficulties to handle.
- alumino-silicate glass Another problem with alumino-silicate glass is the need to be chemically tempered to be used as a protection or a cover glass, to be handled and in order to have sufficient mechanical strength. This causes a large fragmentation of the glass and prevents the use once it is cracked meaning that the glass article exposes in a lot of very small glass pieces. This phenomena is due to the huge and deep interdiffusion coefficient of K+ into the glass matrix during the tempering process.
- DOL depth of layer
- the chemical strengthening of a glass article is a heat induced ion- exchange, involving replacement of smaller alkali sodium ions in the surface layer of glass by larger ions, for example alkali potassium ions. Increased surface compression stress occurs in the glass as the larger ions“wedge” into the small sites formerly occupied by the sodium ions.
- Such a chemical treatment is generally carried out by immerging the glass in an ion-exchange molten bath containing one or more molten salt(s) of the larger ions, with a precise control of temperature and time.
- Aluminosilicate-type glass compositions such as for example those from the products range DragonTrail® from Asahi Glass Co. or those from the products range Gorilla® from Corning Inc., are also known to be very efficient for chemical tempering.
- the invention relates to an
- improved laminated assembly comprising a chemically tempered glass sheet and a panel maintained together by a polymer interlayer.

- tempering time t
- ion exchange depth d.
- the latter is measured either by Scanning Electron Microprobe on the polished section of the chemically tempered glass, or by optical diffractometric method on the face of the tempered glass, with equipment like FSM, a surface stress meter. Then the interdiffusion coefficient can be calculated as follows :
- the glass To determine the interdiffusion coefficient, D, the glass must be chemically tempered with a known temperature and a known duration, and the CS and DoL measured. If this glass is already tempered, the glass has to be polished to remove a depth higher than the exchange depth. Typically polishing more than 100 pm is enough. A after the polishing, the glass sheet has to be chemically tempered to determine the interdiffusion coefficient.
- the glass sheet has a thickness equal to or lower than 25 mm, preferably equal to or lower than 6 mm, more preferably equal to or lower than 3 mm.
- the glass sheet has a thickness equal to or greater than 0.1 mm, preferably equal to or greater than 0.2 mm, more preferably equal to or greater than 0.5 mm.

- the panel can be used to ensure the structural properties of the laminated assembly allowing to reduce the thickness of the glass sheet in order to reduce the weight of the assembly.
- the panel can also be used as a decorative element or to give specific properties to the laminated assembly such as electrical conductivity, lighting functions or any other properties know by the skilled man in the art.
- the thickness of the layer of material is comprises between 0.1 mm to 50 cm meaning that the layer of material can be a thin slice of material but also can have a thick piece of material.

- the glass pane can be obtained by a floating process, a drawing process, a rolling process or any other process known to manufacture a glass pane starting from a molten glass composition.

- At least one glass sheet of the laminated assembly can be at least partially etched or painted to give an additional aesthetic or decorative aspect to the laminated assembly.

- At least one glass sheet of the panel is prestressed, preferably tempered and more preferably chemically tempered to reinforce the assembly.
- prestressed glass means a heat strengthened glass, a thermally toughened glass, or a chemically strengthened glass.
- Heat strengthened glass is heat treated using a method of controlled
- This heat treatment method delivers a glass with a bending strength greater than annealed glass but less than thermally toughened safety glass.
- Thermally toughened glass is heat treated using a method of controlled heating and cooling which puts the glass surface under compression and the core glass under tension. Such stresses cause the glass, when impacted, to break into small granular particles instead of splintering into jagged shards. The granular particles are less likely to injure occupants or damage objects.
- At least one glass sheet of the panel has a interdiffusion coefficient of K+ into the glass matrix at 420°C is included in the range from 2.0 x10 15 m 2 /s to 20.0 x10 15 m 2 /s, for a chemical tempering process of glass in a molten salt containing potassium.

- PVB polyvinyl butyral
- the at least one polymer interlayer comprises a material selected from the group consisting of ethylene vinyl acetate, and/or polyvinyl butyral, more preferably polyvinyl butyral.

- present invention is a transparent or translucent polymer interlayer.
- the polymer interlayer may be coloured or patterned.
- Typical thicknesses (measured in the direction normal to the plane, P) for the at least one polymer interlayer are 0.3 mm to 3.5 mm, preferably 0.75 mm to 1.75 mm.
- Commercially available polymer interlayers are polyvinyl butyral (PVB) layers of 0.38 mm, 0.76 mm, 1.52 mm, 2.28 m and 3.04 mm. To achieve the desired thickness, one or more of those layers can be used.
- PVB polyvinyl butyral polymer interlayers are preferably used.
- Polyvinyl butyral (or PVB) is a resin known for applications that require strong binding, optical clarity, adhesion to many surfaces, toughness and flexibility.
- PVB- films are prepared from polyvinyl alcohol by reaction with butyraldehyde.
- Trade names for PVB- films include KB PVB, Saflex, GlasNovations, WINLITE, S-Lec, Trosifol and EVERLAM.
- the bonding process takes place under heat and pressure also designated as autoclave process which is well known in the art.
- the PVB interlayer becomes optically clear and binds the two panes of glass together. Once sealed together, the laminate behaves as a single unit and looks like normal glass.
- the polymer interlayer of PVB is tough and ductile, so brittle cracks will not pass from one side of the laminate to the other.
- Another process known in the art and preferred for the present invention is the autoclave free laminated glass production.
- This process reduces energy costs but has the drawback of limiting the types and thickness of polymer interlayer.
- Autoclave free oven makes preferentially EVA and dedicated PVB laminated glass. In such case, to achieve the desired thickness and security requirements, one or more of those autoclave free polymer interlayers can be used.
