Definitions
- the present invention relates to laminated glazing for all applications, especially for transport vehicles and in particular as automobile windshields, or for the building, and which comprise a functional layer such as heatable (anti-freeze, anti-fog) and / or sunscreen. that is to say, intended to reflect a more or less significant fraction of the solar radiation to limit the heating of a passenger compartment of a transport vehicle or a building enclosure.
- a functional layer such as heatable (anti-freeze, anti-fog) and / or sunscreen.
- the term "layer” frequently refers to a stack of thin layers of thicknesses as small as of the order of a few nanometers, in particular formed by a vacuum process, in particular by magnetron assisted sputtering.
- a heatable functional layer is electroconductive and connected to a current source via bus bars formed in contact with the layer.
- a functional layer designates, for example, in a privileged manner a ClimaCoat® stack marketed by Saint-Gobain Sekurit, which is heatable, anti-fog / anti-fog and antisolar. This type of stacking saves 0.1 1/100 km by reducing the need to use air conditioning.
- It may be a stack of three layers of silver, as described in the application WO 2010/037968, with two or four layers of silver, of any other layer / functional heatable stack such as ITO (oxide indium doped with tin) but also non heatable.
- ITO oxide indium doped with tin
- the faces of the glass sheets of a laminated glazing are numbered from 1 for the face in contact with the external atmosphere, then 2 for the face of the same glass sheet oriented towards the passenger compartment of the vehicle transport or inside the building, then from the outside to the inside, consecutively 3 and 4 for both sides of the second glass sheet, and so on if more than two sheets of glass are present, all the glass sheets being glued in pairs by a polyvinyl butyral (PVB), ethylene-vinyl acetate (EVA) interlayer adhesive or the like.
- PVB polyvinyl butyral
- EVA ethylene-vinyl acetate
- the functional layer is unglazed, that is to say eliminated on a peripheral fraction of the surface of the glazing, for example with a wire brush, it may be necessary for the sake of aesthetics to hide the edge of the glass.
- the functional layer unmasked from the outside, for example by depositing at the periphery of the face 2 of the laminated glazing (inner face of the first outer glass sheet) an opaque enamel peripheral band, for example black.
- the deposition of a functional layer in face 2 of a laminated glazing can be advantageous compared to a deposition in face 3: obviously when it is a deicing layer, bring the heating layer of the frost is advantageous.
- the object of the invention is therefore to provide improved functional laminated glazings with esthetic qualities that are at least preserved.
- the subject of the invention is a laminated glazing unit comprising a first and a second glass sheet bonded to one another by an interlayer adhesive layer, characterized in that the face of the first glass sheet facing the second comprises an opaque enamel peripheral strip and an ungured functional layer whose edge covers the peripheral enamel band being entirely located inside the surface thereof, and that the second glass sheet has a thickness strictly less than 1, 4 mm.
- the opaque enamel peripheral band hides the edge of the functional layer unmasked from the outside.
- the deicing efficiency is increased compared to a deicing layer on the face 3 of the glazing, and therefore further away from the frost to be removed; there is no screen effect of the interlayer adhesive layer unlike a deicing layer in front 3.
- the first glass sheet has a thickness of at least 1.4 mm and is not quenched.
- a relatively large thickness makes the handling and implementation of the sheet easier on an industrial scale.
- the tools for depositing layers, processing ... glass sheets on industrial chains, are adapted to these thicknesses.
- the functional layer deposited on the first glass sheet perfectly resists bending of the sheet and is not degraded at all, it is particularly advantageous to be able to deposit it on a flat substrate; it is known for example that the deposition of a silver trilayer stack (Ag) on a curved substrate leads to a control of the optical properties of the extremely difficult stack, and therefore to a very low deposition efficiency.
- Ag silver trilayer stack
- the second glass sheet has a thickness at most equal to 1.1 mm. This arrangement reduces the weight of the final laminated glazing.
- the display devices on the inner face of the laminated glazing such as head-up displays (HUD -) on the windshields, the fineness of the inner glass sheet induced an almost superposition of the images reflected on the faces 4 and 2 of the laminated glazing, in other words a virtual disappearance of ghost images (ghost images) or double images.
- HUD - head-up displays
- the second glass sheet is a thin glass of thickness at most equal to 1.1 mm
- depositing the functional layer on the first glass is particularly advantageous.
- the conventional industrial thin-layer stacking deposition lines such as the ClimaCoat® product
- magnetron-assisted sputtering being adapted to produce glasses of PLF (Full Width Float) thickness greater than or equal to 1, 4 mm
- deposit on glasses of thickness less than or equal to 1, 1 mm would require substantial modifications of said lines, especially for all glass handling steps (stripping / stacking, conveying, cutting). Otherwise, the production yields would be greatly degraded (glass breaks, deposition efficiency lower than the usual yields), which would not be economically profitable.
- a thin glass sheet in an application of the type of those of the invention, is preferably mechanically reinforced, especially hardened chemical.
- depositing a layer on a chemical toughened glass can only be done after chemical quenching. Indeed, it is impossible to deposit the layer or the stack before performing the chemical quenching, because it would destroy many layers / functional stacks such as those mentioned above. above inhomogeneously.
- the quenching would then be asymmetrical because of the presence of an alkali barrier layer in the functional stack; and asymmetric ion exchange between the two faces of the glass would result in asymmetric mechanical stresses, and finally, curl, rippling on the glass. It is therefore imperative to form the functional layer on the substrate already chemically quenched.
- the bending of a chemically toughened glass sheet would lead to a loss of the chemical quenching (rehomogenization of the ions by thermal diffusion), and consequently reduce the mechanical strength of the thin glass, the chemical quenching is necessarily carried out after the bending the substrate.
- Deposition of a functional layer on a thin sheet of chemically hardened thin glass would therefore be performed on the curved substrate, which is extremely unfavorable as explained above.
- the use of a thin glass sheet in a laminated glazing therefore encourages the functional layer to be deposited on another sheet of glass of the relatively thick, flat laminated glazing before it is bent.
- the invention further relates to a method of manufacturing a laminated glazing as described above.
- a first method comprises the operations of:
- first glass sheet of dimension at least equal to that of a primitive and at most that of a PLF (6 mx 3.21 m) one or more bands of opaque enamel according to a geometry delimiting a portion less than the periphery of the laminated glazing or windows, by screen printing or the like;
- the opaque enamel is generally black and of known compositions; instead of opaque enamel, we can use a silicate paint, black for example.
- Precooking at 500 - 600 ° C has a duration of 1 to 5 min and can be replaced by any suitable drying means without departing from the scope of the invention.
- the first operations of the process, up to the deposition of the functional layer included, are performed indifferently on the primitive of the first glass sheet or conveniently on a glass of larger dimensions from which several primitives can be cut.
- Such larger dimensions may be those of the Full Float Width (PLF) (3.21 m X 6 m) or smaller areas of which one side is 3.21 m (for example 3.21 m X 2 m), in which one can cut several primitives of 1, 50 m X 1 m for example.
- Cutting the primitive of the first glass sheet may be the first step, or performed at any time before the introduction into an assembly line of laminated glass.
- the removal of the functional layer is carried out with a wire brush or equivalent.
- the bus bars can in known manner be made of silver.
- the functional layer is highly resistant to hot bending.
- the opaque enamel tape hides from an outside view the peripheral boundary of the ungapped functional layer as well as bus-bars.
- a second method comprises the operations of:
- the second sheet of glass is subjected to chemical quenching
- a second opaque enamel band is deposited on the bus bars or the functional layer in a geometry delimiting a part at less than the periphery of the laminated glazing, it is dried and precured at a temperature between 500 and 600 ° C; this second opaque enamel band has the function of hiding the bus bars and the peripheral boundary of the functional layer unmasked from a view of the passenger compartment of the vehicle, the interior of the building ..., which does not This is not always necessary depending on the configuration of the body bay or the frame of the laminated glazing.
- a laminated windshield of a motor vehicle is manufactured in accordance with the foregoing teaching.
- the 2.1 mm thick glass sheet is intended to be in contact with the outside atmosphere, that of 1 mm thick with the passenger compartment of the vehicle.
- a strip of black peripheral enamel is deposited by screen printing
- the glass sheet is precooked at a temperature of approximately 550 ° C. for 1 to 5 min in order to completely eliminate the organic binders and to precook the black enamel;
- ClimaCoat® stack sold by the Saint-Gobain Sekurit Company, which is heatable, anti-fog / anti-fog and antisolar, is deposited on the glass sheet by magnetic field-assisted sputtering under reduced pressure; it is a stack of three layers of silver, as described in the application WO 2010/037968.
- the Full Float Width (PLF) glass sheet is then cut into a primer from the glass.
- This primitive and that of the second 1 mm thick glass sheet are introduced into an assembly line of laminated glazings.
- the primitives of the first and second glass sheets are cut to their final shape and passed through the washing machine.
- the second glass sheet 1 mm thick is chemically quenched.
- the laminated glazing unit is assembled by means of a 0.76 mm thick layer of polyvinyl butyral (PVB), by the implementation of various possible and known combinations of thermal cycling means - temperature profiles, increased pressure means and / or reduced.
- PVB polyvinyl butyral
- the laminated glazing provides excellent anti-sun and sunscreen functions sought; its aesthetic appearance meets current requirements.
