Definitions
- the invention relates to a material comprising a transparent substrate coated with a functional coating capable of acting on solar radiation and/or infrared radiation.
- the invention also relates to glazing comprising these materials as well as the use of such materials for manufacturing thermal insulation and/or solar protection glazing.
- glazings can be intended for both buildings and vehicles, in particular with a view to reducing the air conditioning effort and/or preventing excessive overheating, so-called “solar control” glazings.
- the solar factor “FS or g” corresponds to the ratio in % between the total energy entering the room through the glazing and the incident solar energy.
- Known selective glazing comprises transparent substrates coated with a functional coating comprising a stack of several metallic functional layers, each placed between two dielectric coatings.
- a functional coating comprising a stack of several metallic functional layers, each placed between two dielectric coatings.
- These functional coatings are generally obtained by a succession of deposits made by cathode sputtering possibly assisted by a magnetic field.
- the faces of a glazing are designated starting from the outside of the building and by numbering the faces of the substrates from the outside towards the inside of the passenger compartment or the room it equips. This means that the incident sunlight passes through the faces in increasing order of their number.
- Known selective glazing is generally double glazing comprising the functional coating located on face 2, that is to say on the outermost substrate of the building, on its face facing the spacer gas layer.
- the invention relates specifically to highly selective glazing comprising complex silver-based functional coatings.
- silver-based functional coatings are qualified as complex by the number of layers constituting them, by the nature of the materials constituting these layers and by the adjustment of the thickness of these layers.
- silver-based functional coatings are generally more efficient in terms of selectivity compared to other known infrared-reflecting functional coatings such as coatings comprising conductive oxide-based layers.
- One way to increase selectivity is to further increase the number of reflective layers in the IR.
- the multiplication of the layers of agent affects the transmission spectrum of the glazing which takes on a green tint.
- the glazings which comprise these complex functional coatings are generally slightly greenish, or yellowish in transmission.
- Document WO 2006/043026 describes solar control glazing with very low light transmission, in particular laminated comprising a solar control coating (“low E”) on one face and an absorbing layer which absorbs radiation of higher wavelength at 400 nm on another side.
- the absorbent layers described are based on Ti or NiCrN & TiN. It is specified that the absorption in the visible and the IR is substantially constant over the entire spectrum from 400 nm to 100 pm. The TL obtained are 14 and 15%, which limits the applications of these glazings to “privacy glazing”. The energy efficiency is quite low, these glazings are not very selective.
- colored glazing composed of a clear glass substrate on which is deposited a colored coating is known, the colorimetric characteristics of which are easily adjustable and modifiable.
- the coating comprises metallic nanoparticles in an inorganic matrix of an oxide, for example TiOx:Ag.
- the colored coatings respectively exhibit a plasmon absorption peak at 550 nm, 480 nm, 520 nm, and 610 nm (Examples A to D) and 490, 440 and 420 nm (Examples E to G).
- examples A to D it can be seen in fig. 1 that the half-widths are 567, 138, 180 and 194 nm, respectively.
- the goal was not energy efficiency but to provide colored glazing.
- the object of the invention is therefore to develop an anti-sun glazing, in particular the transmission of which is between 30 and 80%, having an improved aesthetic appearance without having too much of an impact on the thermal performance, in particular the selectivity.
- the desired aesthetic is in particular to avoid the greenish coloring in transmission, or even the most neutral coloring possible.
- the applicant has developed a new solution making it possible to adapt the colorimetry of glazing comprising functional coatings without modifying the complex stacking of these functional coatings.
- the greenish appearance is attributable in part to the fact that the glazing comprising functional coatings based on a metallic layer, in particular based on silver, exhibit peaked transmission spectra around 550nm. This phenomenon is accentuated with the number of functional layers in the coating.
- the proposed solution consists in adding a particular colorimetric adjustment absorbing element which selectively absorbs solar radiation in a very limited part of the visible spectrum.
- the absorbent element is an absorbent layer which has an absorption profile with a peak centered between 505 and 555 nm, in particular between 520 and 530 nm.
- the inventors have discovered that the addition of an absorbent layer, selectively absorbing the visible wavelengths responsible for the green color, the peak of which is particularly fine, makes it possible to maintain thermal performance, in particular the selectivity remains high if the absorption peak of the absorbent element has a width at mid-height of less than 50 nm, preferably less than 40 nm.
- the present invention makes it possible to create a satisfactory material without making a complex functional coating refit.
- the invention proposes a method for neutralizing the green color of a material comprising an existing functional coating by inserting a green-absorbing layer.
- the absorption profile in the visible is determined by carrying out the absorption spectrum. It corresponds to the variations of the absorbance according to the wavelength.
- the absorbent layer can be a layer deposited on one of the faces of the glazing, preferably by liquid means; or can be constituted by one of the substrates or by at least one interlayer sheet.
- the absorbent layer has substantially the same surface as that of the functional coating.
- the invention relates to a material comprising one or more transparent substrates, each substrate comprising two main faces
- an absorbent colorimetric adjustment layer whose average absorption peak is centered between 500 and 555 nm, preferably centered between 510 and 540 nm and whose width at mid-height is less than 50 nm, preferably less than 40 nm.
- the absorbent layer comprises an organic pigment, for example of the eosin type.
- the material according to the invention equipping a building or passenger compartment comprises at least two transparent substrates, the faces of each substrate being numbered from the outside towards the interior of the building or passenger compartment, the functional covering being placed on the inside face of the outermost substrate (side 2).
- the material also comprises a lamination interlayer
- the absorbent layer may consist of the lamination interlayer which includes an organic pigment (tinted interlayer).
- the absorbent layer can also be constituted by one of the substrates (colored glass).
- the absorbent layer consists of a layer deposited on one of the faces of one of the substrates.
- the layer is deposited by any known technique for depositing layers, in particular by the liquid route.
- the functional coating that can act on solar radiation and/or infrared radiation comprises one or more metallic functional layers, generally based on silver, each placed between two dielectric coatings.
- the functional coating may in particular comprise one, two, three or four metallic functional layers.
- the functional coating is generally deposited by sputtering assisted by a magnetic field (magnetron process).
- the material according to the invention could also comprise several layers of colorimetric adjustment.
- the invention has the advantage of decoupling the obtaining of the energy performance (selectivity, etc.), largely ensured by the functional coating, and the obtaining of the aesthetic appearance, ensured by the absorbent colorimetric adjustment layer. .
- the colorimetric adjustment absorbent layer influences energy performance but to a lesser extent.
- the solution of the invention has the additional advantage, starting from a single functional coating of high light transmission, of obtaining a whole range of glazing with lower light transmission and/or of varied color. It is no longer necessary to develop for each range of light transmission a complex functional coating presenting both energy performance and colorimetric properties. It suffices, starting from the same complex functional coating, to select the absorbent colorimetric adjustment layer with a less complex structure allowing the desired colors to be obtained.
- the material according to the invention can be in the form of monolithic, laminated and/or multiple glazing, in particular double glazing or triple glazing, or double glazing with laminated outer glass.
- a monolithic glazing comprises a material comprising a transparent substrate. Face 1 is outside the building and therefore constitutes the outer wall of the glazing, face 2 is inside the building and therefore constitutes the inner wall of the glazing.
- a multiple glazing unit comprises at least two substrates separated by at least one spacer gas layer.
- the glazing creates a separation between an exterior space and an interior space.
- Double glazing for example, has 4 faces, face 1 is outside the building and therefore constitutes the outer wall of the glazing, face 4 is inside the building and therefore constitutes the inner wall of the glazing, the faces 2 and 3 being inside the double glazing.
- a laminated glazing comprises at least two substrates separated by at least one lamination insert.
- a laminated glazing therefore comprises at least one structure of the material/lamination insert/additional substrate type.
- all the faces of the additional materials and substrates are numbered and the faces of the lamination inserts are not numbered.
- Face 1 is outside the building and therefore constitutes the outer wall of the glazing
- face 4 is inside the building and therefore constitutes the inner wall of the glazing
- faces 2 and 3 being in contact with the interlayer of leafing.
- a laminated and multiple glazing unit comprises at least three substrates, at least one spacer gas layer, and at least one lamination spacer.
- refractive indices are measured at a wavelength of 550 nm.
