Definitions

• the invention relates to a laminated glass for use in vehicles or the architecture with a selective reflection of electromagnetic radiation from the wavelength spectrum of sunlight.
• optically partially transparent multilayer systems are used.
• Such multilayer systems are used for selective selective influencing of the transmission as well as reflection of electromagnetic radiation emitted by the sun and thereby on substrates which are transparent to the electromagnetic radiation, in particular glass or glass
• the goal is connected to reflect the highest possible proportion of radiation in the non-visible range (eg solar energy range, or near-infrared spectral range), so that the proportion of transmitted solar energy is minimized.
• a particular aim is to increase the value of glass, which is equipped with such a multi-layer system on said carrier, the total solar transmitted transmission T T s (Calculated according to DIN ISO 13837, Case 1) to a maximum of 40%, emitted by the sun and impinging on the earth's surface electromagnetic radiation, to limit.
• the heating is minimized inside rooms or vehicles and the energy cost to create a person in the interior pleasant ambient climate can be reduced.
• multilayer systems have been used for a long time, which are formed on substrates (glass or plastic). These may be alternating layer systems in which high and low refractive layers of dielectric materials are formed on each other.
• oxides and nitrides should have optical refractive indices at a wavelength of 550 nm in the range 1.8 to 2.5.
• reflective metals such as gold or copper, silver or silver alloys (Ag-Au, Ag-Cu, Ag-Pd and others) which have very good optical properties for these applications are preferably used for the metal layers.
• the laminated glass according to the invention has an optical multilayer system with which a total solar transmission T T s ⁇ 40%, a transmission T vis in the wavelength range of visible light> 70%, a reflection in the wavelength range of visible light R vis ⁇ 12% is achieved.
• the optical multilayer system can be formed directly on a glass surface or on an optically transparent polymer film or another suitable carrier material.
• the coated polymer film or a carrier material can be surface-mounted with a bonding agent or an adhesion-promoting film on a glass surface or sandwiched between two glass panes which can be joined together in this way.
• the energy transmission for example the total solar transmission T TS , is determined according to ISO 13837.
• the laminated glass has a reflection color limited by ASTM 308 for transmission and reflection at normal incidence within a color space (color box) bounded by the values Ra * of -5 to 5 and Rb * of -25 to -40, and the reflection color is determined with an illumination source D65 and standard observer 10 °.
• a spectrophotometer preferably with integral sphere, as available, for example, from Perkin Elmer under the type designation PE900.
• the values for the reflection color within the color space (s) can be in a range of ⁇ 5, preferably ⁇ 2 for the values of Ra * and Rb * , lie.
• the size of the color spaces results from production-related layer thickness variations (typically ⁇ 2% of the respective target layer thickness), which influence the exact color layer.
• a multilayer optical system for selective reflection of electromagnetic radiation from the wavelength spectrum of the sunlight may be formed with at least one layer of silver or a silver alloy and at least one dielectric layer.
• a silver layer or a layer formed with a silver alloy may have a layer thickness in the range 5 nm to 25 nm and a dielectric layer may have a layer thickness in the range 5 nm to 150 nm.
• a silver layer or a layer formed with a silver alloy each having a seed layer and a cap layer, is coated over its entire surface on both surfaces
• a silver alloy in which Au, Pd or Cu with small proportions are present.
• the layers are generally referred to as a silver layer.
• the proportion of additional metal contained should be kept very small, possibly less than 2%.
• a multilayer optical system or more of these multilayer systems may be formed on top of one another on the glass or polymer surface.
• use can be made of conventional vacuum coating methods, in particular PVD methods and particularly advantageously magnetron sputtering.
• X with X for example Al 2 0 3 , Ga 2 0 3 , Sn0 2 , ln 2 0 3 or MgO can be used.
• the seed layer and / or the cover layer should have a layer thickness in the range 5 nm to 15 nm and the silver layer a layer thickness between 5 nm and 25 nm, preferably 10 nm.
• the cover layer can also consist of a thin metal layer - a so-called blocking layer - in which blocker coats are typically formed from Ti, NiCr and Cu and have layer thicknesses ⁇ 5 nm.
• two or more can be used in a sequence of coating steps
• a monoseal layer system may be a construction of a dielectric layer, a thin seed layer, a silver layer, a cap layer, and a final dielectric layer.
• the thicknesses of the silver layers and the thicknesses of the dielectric layers should be adapted.
• the dielectric layers present in such a multilayer system usually have a refractive index of n> 1.8 at a wavelength of 550 nm and lower absorption, and may for example be formed from ln 2 0 3 .
• a dielectric layer structure formed between two silver layers which can be composed of cover layer, dielectric layer and seed layer, has the effect of a dielectric spacer layer in an optical filter system for defining the position of the spectral transmission region and the color appearance of a laminated glass.
• the use of dielectric materials as a seed and cover layer is advantageous because the thicknesses of the seed and cover layers contribute to the layer thickness of dielectric spacer layers and thereby produce a corresponding optical effect, like other dielectric materials, so that they contribute to the overall optical effect.
