Definitions
- the present invention relates to the field of decorative glass panels. More specifically, it is intended for decorative panels for interior applications such as partitioning of offices, wall coverings, credenzas, doors and balustrades, or exteriors such as facade glazing, privacy screens and sunshades.
- Glass is a material widely used by architects for the interior design of buildings as well as for their exterior cladding. There is therefore a continual demand for new products to achieve the aesthetic rendering desired by architects.
- Laminated glazing is commonly used in the building sector for their property to be so-called glazing "security". They consist of two sheets of glass bonded together by a lamination interlayer. When it is desired to obtain colored laminated glasses, one of the possibilities is to use a lamination interlayer which is itself colored. The coloring is thus provided during the manufacturing process of the interlayer. This solution is not very flexible for the end user. The coloring (level of color and choice of color) is indeed imposed by the manufacturer of the interlayer and the choice remains limited. In fact, the development of new shades remains problematic for the manufacturer and requires a significant work of adaptation of the formulations to continue to satisfy the customer specifications.
- the change of a component or the proportions of the components in the formulation of the interlayer can affect the performance of the additives and / or the properties of the final product. This is even more so when it is desired to obtain sustained hue, and therefore considerably increase the proportions of dyes in the interlayer. Even if it can be considered, the supply of colored interleaves remains expensive.
- laminated glasses incorporating printed interleaves generally do not have sufficient contrast between the colors, especially between the light colors, to allow a satisfactory distinction of the patterns, in particular when they are exposed outdoors, for example in front of buildings .
- the present invention provides a decorative glass panel to obviate the above disadvantages. More particularly, the present invention relates to a laminated glass comprising a first glass sheet, a second glass sheet and a colored lamination interlayer between the first glass sheet and the second glass sheet, characterized in that a coating is arranged between the first glass sheet and the lamination interlayer, said lining being constituted by the succession of subsequent layers, starting from the surface of the first glass sheet:
- a first stack of dielectric layers optionally, a first stack of dielectric layers
- a second stack of dielectric layers optionally, a second stack of dielectric layers.
- the laminated glass according to the invention makes it possible to widen the choice of aesthetic solutions available without intervening on the formulation of the intermediate of foliation.
- the present invention makes it possible to offer a range of laminated glasses having more sustained colors from already available ranges of colored lamination interleaves.
- the present invention also makes it possible to increase the contrast between the different hues, in particular the light hues. Contrast enhancement is particularly appreciated to improve the visibility of patterns, especially outdoors, whether they are obtained using printed laminated interleaves or from combinations of plain laminated glass panels. different.
- the laminated glass according to the invention comprises a first glass sheet and a second glass sheet each having an inner surface in contact with the lamination interlayer and an outer surface opposite to said inner surface.
- the first and second glass sheets are preferably flat glass sheets, especially sheets of float glass, that is to say having a smooth inner surface and a smooth outer surface.
- smooth surface in the sense of the present invention is meant a surface for which the surface irregularities are such that the incident radiation on the surface is not significantly deflected by these surface irregularities.
- the outer surface of at least one of the first or second glass sheets - optionally each of the first and second glass sheets - may be partially or fully textured.
- a “textured surface” in the sense of the present invention is a surface for which the surface state varies on a scale larger than the wavelength of the radiation incident on the surface, so that the incident radiation is transmitted and reflected. diffusely by the surface.
- Such texturing can be obtained by any known method of texturing, for example by embossing the inner surface of the glass sheet previously heated to a temperature at which it is possible to deform, in particular by rolling by means of a roller having on its surface a texturing complementary to the texturing to be formed on the inner surface of the glass sheet; by abrasion by means of abrasive particles or surfaces, in particular by sanding; by chemical treatment, especially acid treatment; or by etching, possibly using masks to retain at least a portion of the surface of the non-textured substrate.
- the first and second glass sheets are generally clear or extra-clear glass sheets. In some embodiments, however, they may instead be made of tinted glass, such as yellow, blue, green, gray or bronze glass. They typically have a thickness of 2 to 20 mm, in particular 3 to 12 mm, for example 4, 6, 8 or 10 mm.
- the coating disposed between the first sheet of glass and the lamination interlayer is generally in direct contact with the inner surface of the first sheet of glass. It is preferably also in direct contact with the lamination interlayer.
- the second glass sheet is preferably in direct contact with the lamination interlayer.
- an element A "in direct contact” with an element B means that no other element is disposed between said elements A and B. On the contrary, an element A "in contact” with an element B does not exclude the presence of another element between said elements A and B.
- the coating consists of the succession, from the inner surface of the first glass sheet, optionally of a first stack of dielectric layers, a layer based on titanium oxide, and optionally a second stack dielectric layers.
- the term "constituted by” indicates that the coating does not include other layers than those listed above.
- the layer based on titanium oxide is in direct contact on the one hand with the first stack of dielectric layers and on the other hand with the second stack of dielectric layers.
- the coating according to the invention therefore comprises only layers made of dielectric materials. It does not include metal layers, in particular based on silver, platinum, palladium gold, copper or even nickel, NiCr type.
- the coating according to the invention also does not comprise metal nitride layers, in particular of the TiN, NbN or CrN type.
- the coating consists of the succession, from the inner surface of the first glass sheet, of a first stack of dielectric layers, a layer based on titanium oxide, and a second stack of dielectric layers.
- base-based with reference to the composition of a layer means that said layer comprises more than 60%, preferably more than 80%, more preferably more than 90%, and even more than 95% by weight. of the material concerned.
- the layer in question may in particular consist essentially of said material, that is to say comprising more than 99% by weight of said material.
- the layer based on titanium oxide may in particular comprise silicon.
- the overall Si / Ti atomic ratio in said titanium-based layer is preferably 0.01, even 0.05, 0.25, or even 0.20 or 0.15.
- the Si / Ti ratio is preferably homogeneous throughout the thickness of the titanium layer.
- the silicon and titanium atoms preferably represent at least 90%, or even at least 95%, at least 97%, or even all of the atoms other than oxygen in said titanium-based layer.
- the titanium oxide layer generally has a physical thickness of 5 to 70 nm, preferably 20 to 50 nm.
- the titanium oxide layer preferably has a physical thickness of 20 to 50 nm.
- the oxide base layer preferably has a physical thickness of 10 to 50 nm.
- dielectric layer in the sense of the present invention denotes a non-metallic layer, that is to say which is not made of metal.
- This expression denotes in particular a layer made of a material whose ratio between the refractive index and the extinction coefficient (n / k) over the entire range of visible wavelength (from 380 nm to 780 nm) is equal to or greater than 5.
- the dielectric layers of the first stack of dielectric layers and the second stack of dielectric layers are preferably independently selected from layers based on oxides of zinc, silicon, tin, titanium, zirconium, niobium and mixtures thereof, silicon and / or aluminum nitrides, and silicon and / or aluminum oxynitrides.
- the first and second stacks of dielectric layers may independently comprise from 1 to 5 dielectric layers, for example 1, 2 or 3 dielectric layers.
- the coating can thus comprise a total of 3 to 11 layers, for example 3, 4, 5, 6 or 7 layers.
- the overall optical thickness of the first stack of dielectric layers is typically 10 to 150 nm, preferably 20 to 120 nm, for example 20 to 40 nm, 70 to 90 nm or 90 to 110 nm.
- overall optical thickness of a stack is meant the sum of the optical thicknesses of each of the layers constituting the stack, the optical thickness of a layer being defined by the product of the physical thickness of a layer by its refractive index.
