Definitions
- the shaping is all done by cold bending, but systematically with a support glass: whether with a thick tempered glass serving as a support for the lamination, or else with piston glasses to shape a sandwich of thin glasses.
- the shaping of thin glasses is very complex and cold bending therefore seems the best option to obtain this, the solutions proposed systematically involving a “master” glass to guarantee the correct geometry of the sandwich (in the case of small glazings of quarter type, it would therefore be necessary to continue to form a small tempered glass to have a set with a thin glass on one of the two sides).
- the present invention seeks to provide an alternative solution to the prior F at, namely a process making it possible to produce curved and thin laminated glazing in a simple and industrial manner.
- the present invention relates to glazing of curved shape comprising a first sheet of glass with a thickness of less than 1.6 mm and more preferably less than 1.2 mm, a second sheet of glass with a thickness of less than 1 .6mm and more preferably less than 1.2mm, an intermediate film of thickness less than the thickness of the thinnest sheet of glass of the glazing and arranged between the first sheet of glass and the second sheet of glass, the glazing comprising in addition a seal encapsulating all sides of said glazing
- the invention further relates to laminated glazing of curved shape resulting from the assembly of a first sheet of flat glass with a thickness of less than 1.6mm and more preferably less than 1.2mm, of an interlayer sheet and a second sheet of glass with a thickness of less than 1.6mm and more preferably less than 1.2mm, the second sheet of glass also being flat before its assembly with the first sheet of glass and the interlayer sheet, said glazing comprising in addition a seal encapsulating all its sides and in which
- the first glass sheet and/or the second glass sheet is chemically or thermally reinforced.
- the joint is reinforced by a reinforcing element.
- the reinforcing element comprises at least one metal wire embedded in the joint.
- the interlayer film is a sheet made of a PVB or PET type material.
- the interlayer film is a layer deposited on one of the two sheets of glass of said glazing.
- the layer forming the interlayer film is an OCA resin or a natural rosin.
- the glazing has a maximum deflection of 70mm.
- the glazing has a thickness not exceeding 4mm, more preferably 3mm and even more preferably 2mm.
- the glazing has a maximum surface area of 0.8m2.
- the invention further relates to a method of manufacturing curved shaped glazing comprising a first sheet of glass with a thickness of less than 1.6 mm and more preferably less than 1.2 mm, a thermoplastic interlayer sheet and a second sheet of glass with a thickness of less than 1.6mm and more preferably less than 1.2mm, said process comprising:
- the method further comprises, before the assembly step, a step of chemical or thermal reinforcement of the first sheet of glass and/or the second sheet of glass.
- FIG.2 represents curved laminated glazing according to the invention
- a glazing 1 according to the invention is a laminated glazing, visible in [Fig.l], comprising an exterior glass 2 or first sheet, an interior glass 3 or second sheet and an interlayer film 4.
- the interlayer film 4 is arranged between the exterior glass and the interior glass.
- the outer glass 2 is a glass having a thickness less than 1.6mm and more preferably less than 1.2mm.
- the inner glass 3 is a glass having a thickness of less than 1.6mm and more preferably less than 1.2mm.
- the glazing 1 comprises two sheets of glass of the same thickness or of different thicknesses.
- the interlayer film 4 has a thickness less than the thickness of the thinnest glass of the sandwich or in other words whose thickness is less than 50% of the complete glazing thickness.
- the interlayer film has a thickness less than that of the thinnest glass sheet, having the lowest thickness.
- the interlayer film 4 can be in the form of a sheet or a film and be made of a thermoplastic material such as PVB or PET.
- the glazing 1 has a thickness which does not exceed 4mm, more preferably 3mm and even more preferably 2mm.
- the glazing 1 is produced by, firstly, providing the exterior glass and the interior glass.
- the inner glass 3 and the outer glass 2 are assembled with the interlayer film 4, the latter being placed between the two glasses 2, 3 to then undergo the classic assembly process as visible in the figures 3 and 4.
- This assembly process can include a calendering step then a heating step in an autoclave oven. Once the glazing 1 has been formed, the process consists of shape to form a curved glazing.
- the shaping of the glazing 1 is carried out at the same time as its encapsulation.
- encapsulation consists of providing said glazing 1 with a peripheral seal 5, as visible in [Fig.2], going around, extending on all sides of the glazing. This encapsulation is useful for glazing intended to be inserted into a bay.
- This seal 5 is made of a vulcanized TPE type material such as PP/EPDLM or SEBS.
- the encapsulation step uses an encapsulation device comprising a mold 6 in which at least part of the glazing is inserted and into which the seal material is injected as visible in [Fig.5] .
- This mold 6 comprises, for example, at least two matrices enclosing the glazing to form a space 61 into which the material is injected.
- the seal 5 extends over the entire periphery of the glazing, the mold 6 is arranged accordingly.
- the encapsulation device further comprises a means of deforming the glazing 7 used to give curve to said glazing.
- This means of deformation 7 of the glazing comprises at least one actuator 70, as visible in [Fig.9], controlled by a computer to apply at least one force F on the glazing to deform it.
- This force can be the result of at least one suction and/or at least one physical contact such as stretching or pushing as visible in Figures 6 and 7.
- the encapsulation device can be equipped with at least one at least two different actuators 70 to give curve to the glazing.
- the encapsulation device 7 may comprise a finger-type actuator 70 which comes into contact with the glazing to begin to give it a curved shape. Subsequently, at least one suction type actuator 70 such as a suction bell can take over from F finger type actuator.
- the encapsulation device is used to, simultaneously, deposit the seal 5 on the sides of the glazing while deforming it as visible in [Fig.8].
- the advantage of the invention is that the encapsulation seal 5, which is placed simultaneously with the forming of the glazing, which will harden. This hardening of the seal 5 takes place while the forming is still in progress, that is to say that the force exerted on the glazing to give it the desired shape is still applied.
- the seal 5 hardens and reaches a certain level of hardness, it makes it possible to freeze the position of the glazing 1 in opposing its return to its initial position.
- the present invention thus makes it possible to produce thin but laminated glazing 1 and therefore with all the advantages of laminated glass (anti-intrusion / acoustic / anti-UV etc.) while drastically reducing their thickness and their mass.
- the minimum thickness of laminated products is 3.96mm for 8kg/m, the present invention easily allows it to go down to around 3mm (7.5kg/ m2 ) or even 2mm (5kg/ m2 ).
- the glazing according to the invention has a shape which can be cylindrical or spherical or have a complex shape.
- the glazing obtained can have a maximum deflection of 70mm.
- the glazing obtained is also characterized by its surface, this has a maximum value of 0.8m2.
- the area and the deflection value can be linked, that is to say, the larger the area, the greater the deflection. So, for example, for an area of 0.8m2, we could have an arrow of 50mm and for an area of 0.1m2, an arrow of 35mm.
- the outer glass (or first sheet) 2 and/or the inner glass (or second sheet) 3 undergoes, prior to the assembly of the glazing, a hardening or strengthening process.
- This reinforcement can be chemical or thermal.
- this hardening process is chemical quenching. This involves completely immersing the glass used in a bath of molten salts, subjected to a temperature of around 400°.
- the very specific salt bath allows a chemical exchange which will have the effect of lastingly compressing the exterior surface of the glass.
- this hardening process is a thermal reinforcement process. This involves heating the glass then suddenly cooling it to generate a given stress in the glass. Unlike thermal tempering on thick glass in which the stresses in the glass come from a significant thermal gradient, the thermal reinforcement process generates stress via a limited thermal gradient in the glass due to its low thickness.
- the seal 5 is reinforced.
- the joint includes a reinforcing element.
- This reinforcing element comprises, for example, a metal wire placed in the space formed by the mold 6 is overmolded, embedded in the material forming the joint.
- the reinforcement can be in the form of any element that can accomplish the same function.
- This reinforcement of the joint which partly serves to maintain the curve of the glazing, makes it possible to use a less resistant material for the joint.
- this reinforcement of the joint makes it possible to apply greater stress to the glass while ensuring that the joint can maintain this curve.
- the interlayer film 4 between the two glasses is chosen to be thinner than a commonly used PVB interlayer.
- the interlayer is a material of the OCA (Optical clear adhesive) resin or natural rosin type, that is to say that the interlayer is in the form of a layer.
- the glazing manufacturing process comprises the following steps:
- the layer has a thickness less than 1OOpm, ideally 30pm. This layer is dried by UV drying.
- the glasses undergo hardening by chemical quenching
- the chemical quenching is carried out after cutting or before.
- the glasses to form glazing come from large forming glass plates called PLF whose dimensions are for example 3m x 6m. These large plates are then cut to the right shape and dimensions.
- PLF large forming glass plates
