    专利说明:

    [0001] The invention relates to insulating glazing units, comprising stacks of thin layers acting on the solar radiation and intended more particularly for solar protection. BACKGROUND OF THE INVENTION
    [0002] The glazing according to the invention is more particularly adapted to equip buildings, even if it is not limited thereto. It can also be used in the automotive field, such as side window, sunroof or rear window or as oven door.
    [0003] In a known manner, by selecting the chemical nature, the thicknesses and the succession of thin layers constituting the stack, it is possible to have a significant effect on the quantity of energy resulting from the solar radiation entering a room or a cabin. In particular, such glazing avoids excessive internal heating in summer and thus helps to limit the energy consumption necessary for their air conditioning. For the purposes of the present invention, therefore, solar protection glazing, or sunscreen glazing with still insulating glazing, is understood to mean a glazing consisting of a substrate, most often made of glass, coated with thin layer (s), of such whereby the amount of solar radiation (particularly visible and near-infrared radiation) passing through said glazing is substantially decreased, by reference to that passing through the same substrate but taken in isolation. The invention also relates to such a glazing used as a lighter once opacified, so as to be part of a facade cladding panel, and which allows to offer, in combination with glazing for vision, exterior surfaces of buildings entirely glazed and uniform.
    [0004] These layered glazings (and spandrels) are subject to a certain number of constraints: as regards the glazing, the layers used must, in the first place, be sufficiently filtering with respect to the solar radiation, that is to say that is to say that they must allow the thermal insulation while allowing however a substantial part of the light, as measured by the light transmission TL. In addition, these thermal performances must preserve the optical appearance and 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, even in transmission. 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 imposed today strongly: when the glazing 20 consist 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 hardened type or annealed if we 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. Thus, 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 modification / degradation of its general appearance observed before tempering.
    [0005] In particular, we will speak in such a case of "bombable" or "hardenable" layers. 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 solar radiation filtration which are made of nickel-nickel alloy. chromium, optionally nitrided, 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 glazings are good sunscreen glazing, having satisfactory mechanical and chemical durability, but are not really "bumpable" or "hardenable" because the oxide layers surrounding the functional layer can prevent its oxidation during bending or quenching, oxidation accompanied by a change in the light transmission, and the overall appearance of the glazing as a whole. Many studies have recently been made to make the layers bumpable / hardenable in the field of low-emissivity glazing, aiming instead for high light transmissions unlike sunscreens. It has already been proposed to use dielectric layers 20 based on silicon nitride over silver functional layers, this material being relatively inert with respect to the oxidation at high temperature and It has been shown that it is capable of preserving the underlying silver layer, as described in EP-0 718 250. Other layer stacks acting on solar radiation which are presumed to be bumpable / hardenable have been described using functional layers other than silver: Patent 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 NiCr nickel alloy functional layers associated with silicon nitride layers. Patent application WO2007 / 028913 also discloses stacking structures using, 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 relatively efficient in terms of its heat reflection properties derived from solar radiation and relatively simple and economical to deposit by the technique of magnetic field assisted sputtering (magnetron). As described in application WO2007 / 028913, the deposition of a stack of the type previously exposed by the vacuum sputtering techniques of targets makes it possible to deposit stacks of layers whose thickness can be controlled to the nearest nanometer, which allows adjusting the desired colorimetry of the glazing, in particular its colorimetric neutrality. It is stated in this publication that the stack thus deposited also gives satisfaction from the point of view of its mechanical strength properties in temperature, especially under thermal treatment conditions around 600-630 ° C., characteristic of the most common quenching processes. or bending. In particular, the glazing according to the application W02007 / 028913, having undergone such a heat treatment, does not present any significant changes in its properties, either in terms of energy performance or colorimetry. Equipped with such a stack and depending essentially on the thickness of the layer based on titanium oxide, the glazing with antisolar properties obtained have light transmission coefficients (TL) of the order of 75 to 60% and light reflection (RL) of the order of 25 to 40%. The solar factor through the glazing is however at least of the order of 65%, within the meaning of the standard NF EN410 (2011), which can be considered insufficient in external conditions of very strong insolations. The object of the present invention is thus to provide glazings of the same type as those described in application WO2007 / 028913, that is to say the functional layers of which are based on titanium oxide, but of which the insulation performance is improved, in particular whose solar factor is less than 60%, or even less than 55%, while maintaining a sufficient light transmission, in particular greater than or equal to 40%, or even greater than or equal to 45% within the meaning of NF EN410 (2011). According to another important feature of the glazing according to the present invention, they most often have a very low colorimetry in the sense previously described, including after a heat treatment such as bending or quenching or even enamelling. Also, it is possible that such glazings are used in the building sector as lightening glazing once opacified, at least partly or most of the time completely. Lightening glazing, more often referred to as a light in the field, can for example be used to conceal elements of constructions 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 all the building surface. More specifically, for such buildings, given the importance of glass surfaces, the glazing used must have on their entire surface stacks with solar control properties to limit the cost of cooling in summer and preferably the internal thermal insulation properties to reduce energy losses of the building in winter. The windows, 25 present on almost the entire surface of the building, therefore cover both the parts that must offer a significant light transmission (called vision glazing), and those whose transmission must be virtually zero (occultation effect) to hide the structural elements of the building (glazing lighters). For this purpose, it is usual to use opaque enamel layers to achieve such masking. The object of the invention is then to develop a glazing comprising a glass-type substrate carrying thin film coatings acting on incident solar radiation, which allows to solve the problems as previously discussed. In particular, the glazing sought according to the invention has suitable thermal properties for the solar protection of buildings, as well as optical properties, in particular colorimetry and light transmission properties, also suitable for such use, as well as an ability to withstand heat treatments without damage, consisting of quenching, bending or enameling, 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 substrate, preferably glass, said substrate being covered with a coating of dielectric materials on each of its two faces. In the glazing unit 15 according to the invention, each of said coatings consists of a layer based on titanium oxide or a stack of layers of dielectric materials incorporating such a layer based on titanium oxide. According to the present invention, the thickness of the titanium oxide-based layers in each of said coatings is between 10 and 70 nm. For the purposes of the present invention, the layers based on titanium oxide comprise, for the most part, the elements O and Ti, in a ratio preferably close to 2 (even though deviations from this theoretical value are of course possible without departing from the scope of the invention. the present invention, in particular as a function of the deposition conditions of said layer or of a possible doping of said layer). In particular, Ti and O together represent, according to the invention, at least 85% of the atoms present in the layer, and preferably at least 90% or even at least 95% of the atoms present in the layer. According to possible and preferred embodiments of the present invention, which can of course be combined with each other if appropriate: said dielectric materials are chosen from nitrides, oxides or oxynitrides. The dielectric materials, in addition to the layers based on titanium oxide, are chosen from zinc, silicon, tin, zinc and tin oxides, silicon and / or aluminum nitrides, oxynitrides of silicon and / or aluminum. At least one of said coatings, possibly both coatings, is constituted by a stack according to the succession of the following layers, starting from the surface of the glass: an underlayer or a set of sub-layers, said one or more overcoats consisting of dielectric materials, - a layer based on titanium oxide whose thickness is between 10 and 70 nm, Preferably, such a stack further comprises an overlayer or a set of overlays, or said overlays being made of dielectric materials. Such a stack preferably has the following characteristics: 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 layer based on titanium oxide, 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 layer based on titanium oxide, 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-based layer, the succession of an overlay based on silicon oxide, preferably of physical thickness between 5 and 10 nm, and a overcoat based on titanium oxide, preferably with a thickness of between 1 and 3 nm. At least one of said coatings, or both coatings, is constituted by a single layer based on titanium oxide, preferably deposited by pyrolysis. - The glazing comprises on a first face of the substrate a first coating deposited by CVD, in particular by pyrolysis and on a second side of the substrate a second coating deposited by a vacuum deposition technique, in particular sputtering. In particular, according to this embodiment, the coating deposited by pyrolysis is a layer based on titanium oxide and the coating deposited by a vacuum deposition technique is a stack of layers and constituted by the succession of the following layers, starting from the surface of the glass: an underlayer or a set of underlays, the at least one layer consisting of dielectric materials, a layer based on titanium oxide having a thickness of between 10 and 70 nm, Preferably, such a stack further comprises an overlayer or a set of overlays, the one or more overcoats being made of dielectric materials. Of course, the preferred embodiments of such a stack as previously described applies to this embodiment. According to another embodiment, the glazing comprises on each of its faces a coating deposited by a vacuum technique and constituted by the succession of subsequent layers, from the surface of the glass: an underlayer or a set of sub-layers; layers, the one or more overcoats consisting of dielectric materials, - a layer based on titanium oxide whose thickness is between 10 and 70 nm. Preferably, such a stack further comprises an overlayer or a set of overlays. said one or more overcoats being made of dielectric materials. According to another alternative, at least one of the coatings deposited by a vacuum technique, or both coatings, may be constituted by a single layer based on titanium oxide.
    [0006] Of course, the preferred embodiments of such a stack as previously described applies to this embodiment. At least one titanium oxide-based layer further comprises an element X chosen from silicon, zirconium, niobium and tantalum, the overall X / Ti atomic ratio in said layer being between 0.01 and 0; , 25, Ti and X representing at least 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 the atoms other than oxygen. According to such a mode, X is very preferably silicon.
    [0007] According to one such embodiment in which X is silicon: according to a first embodiment, said Si / Ti ratio is homogeneous throughout the thickness of the titanium oxide-based 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. According to an alternative or complementary mode, at least one layer based on titanium oxide, or even the set of layers based on titanium oxide in said coatings, consists essentially of titanium and oxygen. The at least one titanium oxide-based layer comprises, in particular, less than 1 mol% of elements other than titanium and oxygen. The thickness of the titanium oxide-based layers in each coating is between 20 and 60 nanometers, preferably between 30 and 55 nm. - The light reflection on each side of the glazing is greater than 30%. - The solar factor of the glazing is less than 60%, preferably wherein the solar factor is less than 55%. 5 - The light transmittance of the glazing is between 45 and 60%. - The glazing has undergone a heat treatment such as bending, quenching and / or annealing. According to the invention, the overcoat or underlays of dielectric materials of the stack, in particular those based on silicon, in particular oxide, nitride or silicon oxynitride, may also contain a metal minority relative to silicon, for example aluminum, for example up to 10 mol% relative to silicon. This is particularly useful for accelerating magnetic and magnetic field assisted sputtering of the layer, where the silicon target is made more conductive by "doping" with aluminum. Within the meaning 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 are conventionally understood to mean the product of its real (physical) thickness 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. The subject matter of the invention is "monolithic" glazings (that is to say constituted by a single substrate) or multiple insulating glazings of the double-glazed or even triple-glazed type, of which at least one of the constituents ( leaflets) is glazing according to the invention.
    [0008] The glazings of particular interest to the invention have a TL of the order of 40 to 60%, in particular between 45 and 60%, and an energy transmission, measured by the solar factor, close to the value of TL, at 5%. % near. 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 *) 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. For the purposes of the present description, the optical and energy magnitudes according to the invention are measured according to the data reported in standard NF EN410 (2011 version). 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 lime. 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 a satisfactory durability, without annoying deterioration of the layers of the stack in contact with the enamel during its cooking, or over time once the glazing mounted. If the application more particularly targeted by the invention is glazing for the building (including residential), it is clear that other applications are possible, especially in the windows of vehicles (apart from the windshield where a very high light transmission is required, such as side windows, car roof, rear window or oven doors. The advantages of the present invention are illustrated by means 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. All layers are deposited by pyrolysis or by well-known magnetic field assisted sputtering techniques. More specifically: the layers based on titanium oxide are deposited either by pyrolysis (sputtering of organometallic precursors of titanium on the surface of the hot glass at the outlet of the float bath) or from titanium-based metal targets (the targets being sprayed in an oxidizing atmosphere), the silicon nitride layers are deposited from a metal silicon target comprising 8% by weight of aluminum, pulverized in a reactive atmosphere containing nitrogen (40% by weight). and 60% N2). 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, but this time sprayed in an oxidizing reactive atmosphere, according to the techniques well known in the art. EXAMPLE 1 (prior art): In this example obtained according to the teaching of the application WO2007 / 028913, a stack consisting of a sub-layer of silicon nitride, a layer of titanium oxide TiOX and of an overlay of SiO 2 is deposited on one side of the glass substrate by magnetic field assisted sputtering techniques as previously described.
    [0009] The glazing provided with its stack is shown schematically by the following sequence: Glass / SiN ,, (23 nm) / TiO x (30 nm) / SiO 2 (7 nm) EXAMPLE 2 (Comparative): In this comparative example, a stack of the same kind that the one described in Example 1 is deposited on the same substrate with the only difference that the device is set so that the TiOX layer is twice as thick (60 nm). The glazing with its stack is shown schematically by the following sequence: Glass / SiN ,, (23 nm) / TiO x (60 nm) / SiO 2 (7 nm). EXAMPLE 3 (Comparative): In this comparative example, a stack of the same The nature of that described in Example 1 is deposited on the same substrate with the only difference that the deposited TiOX layer is even thicker, to reach a thickness equal to 70 nm. The glazing provided with its stack is shown schematically by the following sequence: Glass / SiN 3 (23 nm) / TiO 2 (70 nm) / SiO 2 (7 nm) EXAMPLE 4 (according to the invention) In this example according to US Pat. In the invention, a stack similar to that described according to Example 1 is deposited on a glass substrate of the same type by vacuum sputtering techniques. The other side is this time provided with a pyrolytic coating of titanium oxide, previously deposited on the hot glass ribbon at the outlet of the float bath, according to conventional techniques in the field. The glazing provided with the two coatings on each of its faces is shown schematically by the following sequence: TiO 2 pyro (30 nm) / glass / SiN 3 (23 nm) / TiO 2 (30 nm) / SiO 2 (7 nm). Example 1, according to Examples 2 and 3, an excess thickness of TiO 2 is deposited in the stack of layers in order to improve the solar protection performance of the glazing unit.
    [0010] Alternatively, according to Example 4 according to the invention, this same additional amount of TiO 2 is added to the glazing of Example 1, but on the other side of the glazing and not within the stack. The optical properties and the colorimetry of the different glazings thus obtained according to Examples 1 to 4 are measured according to the following criteria in accordance with the NF EN410 (2011) standard: - TL transmission: light transmission in% according to the illuminant D65, - reflection luminous glass side: (RLv) in ') / 0, 15 - a * (Rv), b * (Rv): colorimetric coordinates in external reflection according to the colorimetry system L *, a *, b *. - light reflection on the layer side: (R1_, c) in `) / 0, - a * (Rc), b * (Rc): colorimetric coordinates in external reflection according to the colorimetry system L *, a *, b * 20 Factor solar FS in `) / 0 which measures the ratio between the total energy entering the room and the incident solar energy.

    [0011] The comparison of Examples 1 to 3 show that increasing the thickness of the titanium oxide layer within a stack present on a single face of the glass substrate does not lead to improvement of the insulation properties. glazing, as indicated by the solar factor values reported in Table 1.
    [0012] On the contrary, the deposition of a layer of titanium oxide corresponding to the thickening of the layer according to Example 2, but this time on the other side of the glass substrate (Example 4 according to the invention) this time causes a significant improvement in the energy insulating properties of the glazing, while preserving a light transmission of greater than 50%. The previous stacks are then subjected to the same heat treatment as that indicated in the previous application W02007 / 028913, consisting of heating at 620 ° C for 10 minutes, followed by quenching in air.
    [0013] We define the colorimetric variation AE * in the following way: AE * = (AL * 2 + Aa * 2 + Ab * 2) 1/2, with AL *, Aa * and Ab * the difference in the measurements 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.
    [0014] No optical defects of the type microcracks or pinholes are observed on the three windows. Examples 5 to 10 (according to the invention) In these examples, single layers of titanium oxide are coated on the Planilux® glass substrate by vacuum cathode sputtering techniques on each of its faces. For each example, different thicknesses are deposited, as reported in Table 2 below.
    [0015] The glazing provided with the two layers of titanium oxide is shown schematically by the following sequence: TiOX (xi nm) / Glass / TiOX (x2 nm) The luminous and energetic characteristics of the various glazings obtained are measured as previously indicated and shown in the table 2 next: EXAMPLE THICKNESS THICKNESS TRANSMISSION TRANSMISSION layer TiO2 layer TiO2 ENERGETIC first face second face (Solar Factor) (xi) (x2) Ti a * b * FS (%) Example 5 55 10 58 1 1 62 (invention) Example 6 55 Example 5 55 (Example 5) Example 5 55 40 50 45 (Example 5) (invention) Table 2 The results reported in Table 2 show that the solar factor 5 can be brought to much lower values by application of the present invention and can in particular be lowered by 13% (in absolute value) relative to the best performance observed according to the configurations of the prior art (example 1 above), which appears quite considerable for the application 10 sought. Thus, in all cases, the energetic performances observed for the glazings according to the invention are greater than that which can be obtained according to the teaching of the application WO2007 / 028913, the light transmission remaining at an acceptable level for use particularly in the building or else 15 as side glazing.
