Definitions
- Laminated glazing comprising a transparent substrate with a heating layer having flow lines the whole of which is of variable width
- the glazing of transport vehicles (planes, trains, helicopters, boats, cars ...) and, in some cases, the glazing of buildings can be fitted with heating functions integrated into the glazing to prevent / eliminate, as appropriate. fogging on the inside or frost on the outside.
- Heating is characterized by its specific power (W / m 2 ) which is
- the heating system consists for example of son screen printed on the
- the heating system is supplied via electrodes at a voltage available on the vehicle or the building.
- glass is meant here in a preferred manner any mineral glass, but also a rigid transparent substrate of polymer material of which a typical example is
- PMMA poly (methyl methacrylate)
- electrical conductivity gradient typically obtained by a thickness gradient of the electrically conductive layer such as conductive metal oxide (typically ITO); large variations in layer thickness make it possible to limit the current density in certain parts of the heating surface; the more complex the shape, the more the thickness gradient is marked and difficult to achieve from an industrial point of view;
- ITO conductive metal oxide
- the means put in place to deposit the thickness gradient of electrically conductive layer can be difficult to control and the overall electrical resistance of the layer, over the entire surface of the glazing, can vary significantly.
- the nominal total power for an overall resistance R of the electrically conductive layer is equal to U 2 / R; if this overall resistance R is too low this may result in too high power (too much power consumed by the heating system) and in the extreme case, the product will have to be discarded, the product no longer being within the required tolerances .
- the heated glazing is of complex shape and that flow lines are made on the electrically conductive layer so as to guide the electric current and to a certain extent homogenize the local heating power density, inhomogeneities of this power density over the entire surface of the glazing may nevertheless remain; in particular in acute angles of the surface of the glazing, the density of heating power is lower, insufficiently high.
- the power P dissipated locally is equal to Ri 2
- the power density Ps is equal to P / S, in Watt / dm 2 for example, S being the area between two flow lines.
- the invention therefore endeavors to design a heated glazing whose nominal power does not exceed a certain maximum value, and whose power densities are homogenized to a controlled extent over the entire surface glazing, and in particular whose minimum power densities, in certain corner areas for example, are increased.
- laminated glazing consisting of several rigid transparent substrates bonded to one another in pairs by means of an adhesive layer
- interlayer at least one of these transparent substrates being coated with an electrically conductive layer, an area of this transparent substrate having four opposite edges in pairs, a first and a second bus bar being arranged along two opposite edges, the electrically conductive layer having flow lines for guiding the electric current between the bus bars, characterized in that the set of flow lines is of variable width.
- variable width flux lines makes it possible to better control the ohmic resistance of the layer and to best adjust the power consumed by the layer.
- the widening of the flux lines correlatively decreases the width of the electroconductive bands having the consequence both of increasing their resistance R and decreasing their surface S, a double source of increase of. the power density Ri 2 / S locally.
- the invention makes it possible to substantially reduce cold spots, even in the absence of a thickness gradient of the heating layer.
- the electrically conductive layer is based on doped metal oxide such as indium oxide doped with tin (ITO) and / or tin oxide doped with fluorine SnÜ2: F and / or zinc oxide doped aluminum (AZO), and / or a metal such as Au gold and / or Ag silver, optionally in the form of a multilayer stack, in particular of the type comprising at least one layer of silver;
- doped metal oxide such as indium oxide doped with tin (ITO) and / or tin oxide doped with fluorine SnÜ2: F and / or zinc oxide doped aluminum (AZO), and / or a metal such as Au gold and / or Ag silver, optionally in the form of a multilayer stack, in particular of the type comprising at least one layer of silver;
- the electrically conductive layer has a thickness between 2 and 1600 nm;
- the electrically conductive layer has a thickness gradient, that is to say a variation of its thickness; which is not constant;
- the flow lines have a width of between 5 and 1000 ⁇ m;
- the distance between two neighboring flux lines is at least equal to 8, at most 40, and in order of preferably increasing to 30, 25 and 20 mm;
- the electrically conductive layer has phase separation lines consisting of ablation lines of width between 500 and 2000 pm; these phase separation lines delimit three zones of different phases in the implementation of three-phase current;
- said rigid transparent substrates are made of glass such as soda-lime, aluminosilicate, borosilicate, optionally chemically reinforced, semi-toughened or thermally toughened, or of polymeric material such as poly (methyl methacrylate) (PMMA), polycarbonate ( PC), poly (ethylene terephthalate) (PET) or polyurethane (PU);
- PMMA poly (methyl methacrylate)
- PC polycarbonate
- PET poly (ethylene terephthalate)
- PU polyurethane
- the electrically conductive layer is on the inside facing side of the
- laminated glazing of at least one of the two rigid transparent substrates constituting the two exterior surfaces of the laminated glazing;
- the intermediate adhesive layer is chosen from polyvinyl butyral (PVB), polyurethane (PU), poly (ethylene - vinyl acetate) (EVA), ionomer alone or as a mixture of several of them;
- PVB polyvinyl butyral
- PU polyurethane
- EVA poly (ethylene - vinyl acetate)
- a flow line (92; 93) at least has a locally increased width, to locally increase the electrical resistance, locally decrease the surface of the conductive area and locally increase the heating power density, so as to remove a cold spot; this is particularly the case in a corner area of complex shape deviating from a right angle, in which the heating power density is insufficient.
- the invention also relates to a method of manufacturing a laminated glazing described above, comprising the formation on an electrically conductive layer of variable width flow lines controlled by ablation by means of a pulsed laser associated with a scanner to move the laser spot, and / or by localized chemical etching of the electroconductive layer and / or by deposition of a first coating such as an ink in a pattern corresponding to the flux lines, deposition as a second coating of the electroconductive layer, then elimination such as dissolution of said first coating and of the fraction of the electrically conductive layer covering it.
- This latter process is known in English as "I ift-off”.
- Another object of the invention consists in the application of laminated glazing described above, as heated glazing for an air vehicle, land vehicle in particular rail, water in particular marine, armored.
- the faces of said rigid transparent substrates are numbered from that in contact with
- the external atmosphere defined as the face 1 and the electrically conductive layer has a face n of the laminated glazing, with n greater than or equal and preferably equal to 2, for an application as deicing / anti-icing glazing.
- the electrically conductive layer takes up one face n of the laminated glazing, with n greater than or equal to 3, preferably the face oriented towards the inside of the laminated glazing, of the rigid transparent substrate in contact with the interior volume of the vehicle, for an application as defogging / anti-fogging glazing.
- FIG.1 shows a rigid transparent substrate coated with a layer
- FIG.2 is a schematic partial front view of an anti-icing heating layer such as that of [Fig.1] comprising flow lines according to the invention.
- a transparent substrate made of aluminosilicate glass is coated with an electrically conductive layer 2 of indium oxide doped with tin (ITO) of substantially homogeneous thickness, including a zone 1 present.
- ITO indium oxide doped with tin
- Ablation lines of the electroconductive layer 2 constitute flux lines 9 to guide the electric current between the bus bars 7, 8.
- the corner area surrounded in [Fig.1] is an area of lower heating power density than that of the central areas of the anti-icing heating layer 2. In this corner area, the power density is insufficient.
- the flow lines 9 are of variable width according to the invention, as shown [Fig.2]
- the flow line 91 is of constant width 200 m
- the flow line 92 of width constant 600 ⁇ m
- the flow line 93 of width varying from 200 to 600 ⁇ m.
- Tables 1, 2 and 3 below give examples of resistance gain between leads (bus bars) (total resistance) Ra of an ITO electrically conductive layer 200 nm thick, provided with 60 equidistant flux lines , between leads spaced 100 mm apart, depending on the width of the heating layer and the width of the flow lines.
