    [0001] The invention relates to glazing comprising a stack of thin layers acting on the solar radiation and intended more particularly the sun protection. The glazing according to the invention is more particularly adapted to equip buildings, even if it is not limited thereto and that it can also be used in the automotive field, such as side windows, sunroof or rear window. . In a known manner, by selecting the chemical nature, the thicknesses and the succession of the thin layers constituting the stack, it is possible to have a significant effect on the amount of energy of the solar radiation entering or leaving a room or a room. cockpit. In particular, such glazing avoids excessive internal heating in summer and thus helps to limit the energy consumption necessary for their air conditioning. The invention also relates to such glazing used as a lighter once opacified, so as to be part of a facade cladding panel, and which allows, in combination with glazing for vision, to provide external surfaces of fully glazed and uniform buildings. These layered glazings (and spandrels) are subject to a certain number of constraints: as regards the glazings, the layers used must, in the first place, be sufficiently filtering with respect to the solar radiation, that is, that is to say, they must allow the thermal insulation while allowing however to pass at least a portion of the light, as measured by the TL light transmission. In addition, these thermal performances must preserve the optical aspect, the aesthetics of the glazing: it is thus desirable to be able to modulate the level of light transmission of the substrate, while keeping a color judged aesthetic and preferably substantially neutral, especially in external reflection. This is also true of lighters with regard to the aspect in reflection. According to another essential aspect, these layers must also be sufficiently durable, and all the more so if, in the glazing once mounted, they are on one of the outer faces of the glazing (as opposed to the "inner" faces, turned towards the gas gap between double glazing for example). Another constraint is strongly required today: when the glazing consists at least in part of glass substrates, they often undergo one or more heat treatments, for example of the bending type if we want to give them a curve (showcase ), or type toughening or annealing if they want them to be more resistant and therefore less dangerous in case of shocks. If depositing the layers after the heat treatment of the glass is complex and expensive, it is also known that the deposition of the layers on the glass before proceeding to said heat treatment can cause a significant change in properties, including optical and energy, said stacks. In this way, it is sought, and it is the object of the present invention, stacks of thin layers that can be able to withstand heat treatments without significantly modifying the optical / thermal properties of the glazing as a whole and without deteriorating its appearance. general observed before quenching. In particular, we will speak in such a case of "bombable" or "hardenable" layers.
    [0002] An example of anti-solar glazing for the building is given by patents EP-0 511 901 and EP-0 678 483: these are functional layers in terms of filtration of solar radiation which are nickel-chromium alloy optionally nitrided, made of stainless steel or tantalum, and which are arranged between two layers of metal oxide dielectric such as SnO 2, TiO 2 or Ta 2 O 5. These windows are good sunscreen, with satisfactory mechanical and chemical durability, but are not really "bombable" or "hardenable" because the oxide layers surrounding the functional layer can prevent its oxidation during bending or tempering, oxidation accompanied by a change in the light transmission, and the overall appearance of the glazing as a whole. Many studies have been conducted recently to make the layers bumpable / hardenable in the field of low-emissive glazing, aimed rather at high light transmissions unlike sunscreens. It has already been proposed to use, over functional silver layers, dielectric layers based on silicon nitride, this material being relatively inert with respect to the oxidation at high temperature and proving able to preserve the underlying silver layer, as described in EP-0 718 250. Other layer stacks acting on solar radiation presumed to be bumpable / hardenable have been described, using layers other than silver: EP-0 536 607 uses metal nitride functional layers, of the TiN or CrN type, with protective layers of metal or of silicon derivatives, patent EP-0 747 329 describes functional nickel alloy NiCr layers associated with silicon nitride layers. Patent application WO2007 / 028913 also discloses stacking structures which use, as a layer acting mainly on the solar radiation, titanium dioxide (TiO 2) or zirconium dioxide (ZrO 2), this layer being deposited on a sublayer of silicon nitride. Such a product has thus appeared to be relatively efficient with regard to its heat reflection properties derived from solar radiation and which is relatively simple and economical to deposit by magnetron sputtering technique. As described in the application WO2007 / 028913, the deposition of a stack of the type previously exposed by such a technique makes it possible to deposit stacks of layers whose thickness can be controlled to the nearest nanometer, which allows the adjustment of the desired colorimetry of the glazing, in particular its colorimetric neutrality. The stack thus deposited also satisfies the point of view of its mechanical strength properties in temperature, especially in heat treatment conditions around 600-630 ° C, characteristics of the most common quenching or bending processes. Thus, the glazing according to the application W02007 / 028913, having undergone such a heat treatment does not show significant changes in its properties, whether in terms of energy performance, colorimetry. Further, it is stated that such a heat treatment does not result in the appearance of any optical defects such as microcracks or pinholes within the stack, often referred to as microcracks or pineholes in the field. However, the experiments carried out by the Applicant have shown that at higher temperatures, that is, when the quenching, bending or annealing heat treatment is carried out above 650 ° C., although the stacking does not occur. presents no microcrack or other defect, a phenomenon of blur appears, without any particular structural modification observable within the glazing can explain such a phenomenon. By blur, measured as a percentage, it is understood within the meaning of the present invention the loss by diffusion of light, that is to say in a conventional manner the ratio between the diffused part of the light (diffuse fraction or Td). on the light directly transmitted through the glazing (TL), usually expressed in percentages. The diffuse transmission thus measures the light fraction diffused by the layers deposited on the surface of the glass substrate. The blur can classically be measured by spectroscopic techniques, using a spectrophotometer, the integration over the entire visible range (380-780 nm) allowing the determination of the normal transmission TL and the diffuse transmission Td . Also, it is possible that such glazings are used in the building sector as lightening glazing once opacified, at least in part or most of the time completely. The lightening glazing, more often called light in the field, can for example allow to obscure building elements such as electrical wiring, plumbing, air conditioning or more generally all structural elements of the building. In particular, in buildings incorporating very large glazed areas, the use of glazing lighters is advantageous to respect the aesthetics and architectural unity of the large glass area, which can cover almost the entire surface of the building. More specifically, for such buildings, given the importance of glazed surfaces, the glazing used must have on their entire surface stacks with solar control properties to limit the cost of air conditioning in summer and preferably the properties thermal insulation to reduce the energy losses emitted by the building in winter. The glazing, present on almost the whole surface of the building, thus covers at the same time the parts which must offer a significant light transmission (called then vision glazing), and those whose transmission must be practically null (effect of occultation) for hide the structural elements of the building (spandrel glazing). For this purpose, it is usual to use opaque enamel layers to obtain such masking. For a uniform aesthetic since an external vision of the building, it is useful to preserve the system of layers even in the parts coated with enamel, which leads to the need to deposit the enamel on the stack of layers on at least a part, mostly on the whole, of the lightening glazing. On these layers, the application of the enamel layer, in particular the heat treatment required for its formation, can also cause the appearance of defects. In particular, the stacks of layers usually formed by vacuum deposition type sputtering, less resistant than the pyrolytic layers, are generally more fragile at high temperatures and enamel deposition frequently causes visible defects after treatment thermal. More specifically, the enamel as it is deposited in the usual way is composed of a powder containing a glass frit (the vitreous matrix) and pigments used as dyes (the frit and the pigments being based on metal oxides ), and a medium also called vehicle allowing the application of the powder on the glass and its adhesion with it at the time of deposit. To obtain the final enamelled coating, it is necessary to cook it, and it is common that this cooking operation is done concomitantly with the tempering / bending operation of the glass. For more details on enamel compositions, reference may be made to patents FR-2,736,348, WO96 / 41773, EP-718,248, EP-712,813 and EP-636,588. Enamel, mineral coating, is durable , adherent to glass and therefore an ideal opacifying coating. However, as indicated above when the glazing is previously provided with thin layers, its use is delicate because the enamel baking involves a heat treatment at high temperature, generally of the order of 650 ° C or higher, for the stack of layers. At such temperatures, chemicals from the enamel preparation or the enamel itself tend to diffuse into the underlying layers of the stack and chemically modify them. To avoid this phenomenon, the application W02011 / 045412 proposes to use a surface layer (that is to say directly in contact with the enamel) of the stack based on titanium oxide, niobium oxide or tantalum oxide, said surface layer being made more resistant by the incorporation of a metal oxide of the group Ta, Nb, Al, Zr, Hf, V, Mn, Fe, Co, Ni, Cu, Si or Zr.
    [0003] The object of the invention is then to develop a glazing comprising a glass-type substrate carrying a stack of thin layers acting on incident solar radiation, which allows to solve the problems previously discussed. In particular the glazing sought according to the invention has thermal properties suitable for solar protection of buildings, optical colorimetric properties and light transmission also suitable for such use, and an ability to withstand heat treatments without damage, especially an enameling, that is to say without occurrence of blur, even at very high temperature, that is to say greater than or equal to 650 ° C. In its most general form, the present invention relates to a sun protection glazing comprising a preferably glass substrate provided with a stack of thin layers, wherein said stack consists of the succession of the following layers from the glass surface: an underlayer or a set of underlays, the one or more overcoats consisting of dielectric materials, and a layer based on titanium oxide further comprising silicon, the overall Si / Ti atomic ratio. in said layer being between 0.01 and 0.25, a layer in which Si and Ti represent at least 90% of the atoms other than oxygen, preferably at least 95%, or even at least 97% or even all of atoms other than oxygen, the thickness of said layer being between 20 and 70 nm, - an overcoat or a set of overlays, said overlay or layers being made of dielectric materials. According to particular and preferred embodiments of the present invention which can of course possibly be combined with one another: the dielectric materials constituting the overcoats and the underlays are chosen from zinc, silicon and tin oxides; titanium, zinc and tin, silicon and / or aluminum nitrides, silicon and / or aluminum oxynitrides. The overall optical thickness of the sub-layer (s) is between 30 and 90 nm, more preferably between 40 and 70 nm. The overall optical thickness of the overcoat (s) is between 7 and 30 nm, more preferably between 10 and 20 nm. The glazing comprises, between the surface of the glass and the titanium oxide layer, two sub-layers including a layer based on silicon oxide whose physical thickness is preferably between 10 and 20 nm and a silicon nitride-based layer whose physical thickness is preferably between 15 and 25 nm. The glazing comprises, between the surface of the glass and the titanium oxide layer, a single sublayer based on silicon nitride, the physical thickness of which is preferably between 15 and 35 nm. The glazing comprises, above the titanium oxide layer, the succession of an overlay based on silicon oxide, preferably having a physical thickness of between 5 and 10 nm, and an overlayer based on titanium oxide, preferably of thickness between 1 and 3 nm. In a first embodiment, said Si / Ti ratio is homogeneous throughout the thickness of the titanium oxide layer. According to another embodiment different from the previous one, the layer based on titanium oxide comprises a succession of layers in which the Si / Ti ratio varies between 0 and 0.20. The overall Si / Ti atomic ratio in the layer is between 0.05 and 0.20, more preferably between 0.05 and 0.15. The TL light transmission of the glazing is between 50 and 80% and more preferably between 60 and 70% and the solar factor FS is close to the TL value. By the term "neighbor" it is meant that the difference between the two values is less than 5% and more preferably is less than 3%, or even is of the order of a percentage. The glazing according to the invention may have undergone a heat treatment such as bending, quenching and / or annealing. The invention also relates to a spandrel glazing, at least partially opacified, and preferably completely opacified, by an additional coating, said coating being in the form of an enamel or a lacquer. In such lightening glazing the additional coating in the form of enamel or lacquer may be deposited above the stack of layers. The invention finally relates to a multiple glazing, in particular double glazing, incorporating glazing as previously described. As indicated above, the stack of layers according to the invention is enamelable at very high temperatures, in particular of the order of 650 ° C. or even higher, in that the frit of the enamel can be deposited on the surface. facing the uncoated substrate or preferably on the face already coated with the stack of layers and bake it at high temperature without substantially modifying the optical appearance of the glazing as a whole, with reference to a vision glazing provided with the same layers , especially in external reflection. In particular, it is possible according to the invention to deposit the enamel at very high temperature without blur on the glazing. Thanks to such advantages, it becomes possible to propose lighters offering a harmony of color and a great similarity in external appearance with the vision glazing, and thus to constitute uniformly and aesthetically glazed facades. According to the invention, the overlay or underlayer of dielectric materials of the stack, in particular those based on silicon, in particular silicon nitride or oxynitride, may also contain a minority metal relative to silicon, for example aluminum, for example up to 10 mol% relative to silicon. This is particularly useful for accelerating magnetic resistor-assisted sputtering of the layer, where the silicon target is made more conductive by "spiking" with aluminum. For the purposes of the present invention, it is thus more generally understood that the overcoats or underlays of dielectric materials consist essentially of said materials, without excluding, however, that other elements, in particular other cations, are present but in quantity. very minor, especially in order to facilitate the deposition of the layers by the processes used, especially magnetron sputtering. Optical thicknesses within the meaning of the present invention conventionally means the product of its actual thickness (physical) by its refractive index. Thus an optical thickness of 50 nm of Si3N4, whose refractive index is about 2.0, corresponds to a deposit of 25 nanometers (physical thickness) of said material.
    [0004] The subject of the invention is the "monolithic" glazings (that is to say constituted of a single substrate) or the multiple insulating glazings of the double-glazed or even triple-glazed type, of which at least one of the constituents (of the leaflets) is glazing according to the invention. Preferably, whether monolithic glazing or double glazing, the stack of layers are arranged in face 2 or face 4 (conventionally, the faces of the glass substrates are numbered from the outside to the inside of the glass. cabin), and thus provide an optimal effect of protection against solar radiation. Glazing of more particular interest to the invention has a TL of the order of 50 to 80% or 60 to 70%, and a solar factor FS close to the TL value. They also preferentially have a relatively neutral coloration with possibly a blue or green color in external reflection (on the side of the substrate without layers), with in particular in the international colorimetric system (L *, a *, b *) values of a * and b * negative (before and after any heat treatment). There is thus a pleasant shade and low intensity in reflection, sought in the field of building.
    [0005] For the purposes of the present description, the optical and energy magnitudes according to the invention are measured according to the data reported in the international standard IS09050 (2003). The subject of the invention is also the layered substrate at least partially opacified by a coating of lacquer or enamel type, with a view to making lighters, where the opacifying coating may be in direct contact with the face of the substrate already coated with the stack of layers. The stack of layers can be perfectly identical for vision glazing and for the lighter. In particular, according to the invention, the face of the substrate already provided with a stack of thin layers and to which an enamel composition can be deposited according to conventional techniques, without the appearance of optical defects in the substrate, can be considered as "enamelable". stacking, and with a very limited optical evolution, and in particular without the appearance of blur. This also means that the stack has satisfactory durability, without annoying deterioration of the layers of the stack in contact with the enamel or during its cooking, or over time once the glazing mounted.
    [0006] If the application more particularly targeted by the invention is glazing for the building, it is clear that other applications are possible, especially in the windows of vehicles (apart from the windshield where a very demanding high light transmission), such as side glasses, roof-car, rear window.
    [0007] The advantages of the present invention are illustrated with the aid of the following nonlimiting examples, according to the invention and comparative. All the substrates are 6 mm thick clear glass of Planilux type marketed by Saint-Gobain Glass France.
    [0008] All layers are deposited by well-known magnetic field assisted sputtering techniques. More specifically: the layers based on titanium oxide are deposited from titanium metal targets also comprising, according to the examples of silicon or zirconium, the targets being sprayed by a plasma in an oxidizing atmosphere for the deposition of the various layers to titanium oxide base, - the silicon nitride layers are deposited from a metal silicon target comprising 8% by weight of aluminum, sprayed in a reactive atmosphere containing nitrogen (40% Ar and 60%). % N2 for SiNx). The silicon nitride layers therefore also contain a minority amount of aluminum. - The silicon oxide layers are deposited from a metal silicon target of the same composition as the previous one, sprayed in an oxidizing reactive atmosphere. The following examples were made to obtain glazing provided with stacks whose thickness and the nature of the layers is adjusted to obtain the same energy performance, ie a solar factor of 68%. . EXAMPLE 1 In this comparative example and in accordance with the teaching of the previous application WO2007 / 028913, a stack consisting of a sublayer of silicon nitride, a titanium oxide layer TiOX and two overlays on SiO2 and TiOX, is deposited on the glass substrate in the following sequence: Glass / SiN ,, (30 nm) / TiO x (22 nm) / SiO 2 (7 nm) / TiO '(1 nm) In this comparative example, the titanium oxide layer is deposited from a metal target consisting solely of titanium.
    [0009] EXAMPLE 2 In this example according to the invention, a stack similar to that described according to Example 1 is deposited on the same substrate but the TiOX layer is replaced by a layer based on TiOX, also comprising silicon. The layer is deposited from a metal target comprising an alloy of titanium and silicon in an atomic proportion of 90/10. The thicknesses of the various constituent layers of the stack are further adjusted according to the techniques of the art so that the energy performance of the glazing thus obtained is identical to that of the glazing according to Example 1 above. The deposited stack corresponds to the following sequence: Glass / SiN ,, (23 nm) / TiO, 9Si0.10x (31 nm) / SiO2 (7 nm) / TiO '(1 nm) It was verified by ray spectroscopy X (EPMA microprobe) that the atomic proportions of titanium and silicon in the titanium oxide layer deposited in this way substantially correspond to those initially present in the metal target, the measured Si / Ti atomic ratio being approximately 0.1. EXAMPLE 3 In this comparative example, a stack of the same nature as that described according to Example 1 is deposited on the same substrate but the TiOX layer is replaced by a TiOX-based layer also comprising zirconium. The layer is deposited from a metal target comprising an alloy of titanium and zirconium in an atomic proportion of 90/10. The thicknesses of the various constituent layers of the stack are further adjusted according to the techniques of the art so that the energy performance of the glazing thus obtained is identical to that of the glazing according to Example 1 above.
    [0010] The deposited stack therefore corresponds to the following sequence: Glass / SiN ,, (25 nm) / TiO, 9Zr0.10x (30 nm) / SiO 2 (7 nm) / TiO '(1 nm) The optical properties and the colorimetry of the The different glazings thus obtained according to Examples 1 to 3 are measured according to the following criteria: transmission TL: light transmission in λ / 0 according to the illuminant D65, - luminous reflection on the glass side: (RLv) in) / 0.25 - a * (Rv), b * (Rv): colorimetric coordinates in external reflection according to the colorimetry system L *, a *, b *. - light reflection on the layer side: (RL,) in `) / 0, - a * (Rc), b * (Rc): colorimetric coordinates in external reflection according to the colorimetry system L *, a *, b * 30 Energy transmission solar factor FS in)) / 0 which measures the ratio between the total energy entering the room and the incident solar energy.

The previous stacks are then subjected to the same heat treatment as that indicated in the previous application WO2007 / 028913, consisting of heating at 620 ° C. for 10 minutes, followed by quenching. We define AE * in the following way: AE * = (4L * 2 + 4a * 2 + Ab * 2) 1/2, with AL *, Aa * and Ab * the difference in the measures of L *, a * and b * before and after heat treatment. The AE * before and after heat treatment is of the order of or close to 1% and all the glazings retain their anti-solar property unchanged, as measured by the FS factor. They are also perfectly calibrated on the aesthetic level, especially in external reflection where the values of a * and b * are close to zero or slightly negative, giving a very neutral or slightly blue-green color accepted for glazings with strong external reflection. . All the measured values evolve very weakly under the influence of the heat treatment: the values of TL and FS are conserved to about 1% close, the colorimetric data change very little, there is no change from one shade to another hue in external reflection. No optical defects of the type microcracks or pinholes are observed on the three windows.
    [0012] The resistance of the stacks to heat treatments at a higher temperature is then measured according to the following experimental protocol: Lamellae of the same glazings as previously described according to Examples 1 to 3 are initially coated with an enamelling tab at above the stack of thin layers, deposited by screen printing and consolidated by drying at 160 ° C. The lamellae are then subjected to heat treatment in a gradient oven comprising 3 zones of different strengths.
    [0013] The setpoints of the 3 zones are initially adjusted so that the temperature experienced by the lamellae varies from one end to the other between 580 and 680 ° C. The gradient is measured at the outlet of the gradient furnace glass using a pyrometer which records 14 measurement points on the enamel. After cooling, it is verified that none of the samples has an optical defect of the type microcracks or holes (pinholes). The surface of the stacks on the three samples thus appears regular, homogeneous and without defects.
    [0014] The measurement of the parameters L *, a *, b * in reflection is carried out in a second step through the glass on the side of the uncoated side (that is to say on the glass side). The measurement is carried out using a Minolta CM-600d commercial spectrocolorimeter in D65 mode (illuminant D65). Such a measurement appears representative of the observation of a glazing from the outside. In addition, it is an indirect measure of the blur generated on the surface of the glazing, seen from the outside. In particular, the black enamel layer being an absorbing layer of the light directly transmitted through the glazing, the parameter L * measured in reflection by the spectrocolorimeter on the surface of the lamella (glass side) is directly proportional to the diffusion of the light generated at the level of the stack of thin layers. In other words, the parameter L * measured on the glass side is all the more important since the scattered fraction of light by the glazing (in particular by the stack of layers) is important. The tests carried out by the applicant company have shown that a measured value of L * of the order of 10 or higher appears perceptible to the naked eye. In particular, beyond this critical value of the blur, the glazing loses its transparency and has an undesirable milky (translucent) appearance, especially since the L * is high. The various values thus measured of L * are plotted in FIG. 1, as a function of the temperature gradient undergone by the different samples. Significant differences in the fuzziness can be observed depending on the nature of the layer based on titanium oxide present in the stack, and in particular on the critical heating temperature beyond which the glazing provided with its stack has a value L * that is too great, that is to say typically greater than 10: This temperature is 610 ° C for the glazing comprising the TiOx layer only, 640 ° C for the glazing comprising the Tio layer, 9Zro, 10x and 675 ° C for the glazing comprising the Tio layer, 9Si0, 10. In particular, the data shown in the graph of FIG. 1 show that only the glazing comprising the Tio layer, 9Si0, 10 , in the solar control stack can undergo a heat treatment of the order of 650 ° C, especially necessary in a method of depositing a black email on the surface of the glazing. In conclusion, the solar protection glazings according to the invention are very advantageous for equipping buildings, without excluding applications in the automobile and all vehicles: the side windows, the rear windows, the roof-car, which can moreover present enamelled coatings. With a stack of layers fixed, in particular according to the values of TL and energy transmission (FS) that we are looking for, we can thus, without having to modify, manufacture glasses for vision that are not intended to undergo heat treatments or which must be bent / tempered / annealed, make lighters in good colorimetric harmony with visions glazings, which can be lacquered or enamelled: it can thus standardize the manufacture of interference layers on large substrates, which is a great advantage on the industrial level.
