Definitions
- the invention relates to a laminated pane which has the features of the preamble of claim 1 and the use of this laminated pane.
- Glazed glass panes are widely used in vehicles and buildings. They perform several functions, such as closing openings and eliminating the risk of injury in case they are destroyed. In addition, these glazings must often not on the one hand not let all the incident solar radiation to not excessively heat the interior space, and secondly pass a sufficiently large amount of light to illuminate enough space inside. Compliance with these two requirements, namely to prevent the excessive entry of energy radiation and to sufficiently illuminate the interior space, constitutes a compromise. There is therefore a demand for laminated glass with increased selectivity in terms of transparency to energy and transparency to light.
- German patent DE 199 27 683 Cl discloses a transparent laminated glass pane consisting of at least two solid glass panes and a transparent bonding layer which connects them to each other, the laminated pane made of glass having a sun protection layer which reflects the infrared radiation.
- the laminated glass pane is characterized in that another transparent layer which essentially reflects the radiation thermal is provided on its surface facing the interior space.
- the glass laminated glass still fulfills a thermal protection function.
- the sun protection function is particularly effective when the layers of the glass laminated pane arranged in front of the sun protection layer are transparent.
- the thermal protection function is achieved by reflecting the long-wave infrared radiation that comes from the interior space to return it to the interior space.
- German Patent Specification DE 102 49 263 B4 discloses thermal comfort glazing which comprises a darkening glass pane and a low E layer, the low E layer being disposed on the space-facing surface. inside the vehicle. In summer, the low E layer has the effect of reducing the radiation temperature of the glass surface towards the inside of the vehicle. In winter, the low E layer must have the effect of reflecting the infrared radiation emitted by the passengers of the vehicle by reflection towards the interior of the vehicle.
- the glazing consists of four layers, namely, starting from the outside, a first glass pane, a sheet of SPD ("suspended particle device") which has an effect of shading, a second glass pane and a low E layer disposed on the latter and turned towards the interior space of the vehicle.
- WO 2005/01 2200 A1 discloses a transparent support having a low solar coefficient and having a system of several layers.
- the layer system is constituted, starting from the support, of a first layer of a dielectric material, a first absorbing layer, a layer which reflects the infrared radiation, a second absorbent layer and a closure layer of dielectric material.
- the absorption of light by the coated support must be greater than or equal to 35% when the support is a transparent glass pane with lime and soda with a thickness of 6 mm.
- the problem underlying the invention is to provide a laminated glass easy to manufacture and which provides an increased sensation of thermal comfort.
- the laminated pane according to the invention therefore consists of two individual tinted windows which absorb the radiation and which are integrally connected to one another by means of an intermediate layer, a system of layers which allows visible light to pass through. a defined frame being disposed within the laminated pane. The part of the radiation that strikes the layer system and does not pass through it is reflected, absorbed or reflected and absorbed by this layer system depending on its nature and structure. The layer system thus selectively acts on the incident radiation spectrum.
- individual tinted glass absorbs another part of the infrared radiation, while visible light is not absorbed to the same extent.
- Individual windows therefore also have a selective effect. Indeed, thanks to its multiple filtering effect, whereby the infrared radiation and in particular the near infrared radiation are prevented to a greater extent from penetrating into the interior space in the form of visible light, the laminated glass according to the The invention has a higher selectivity than laminated glass usually used or that individual tinted windows known.
- the layer system used in the laminated pane according to the invention is transparent to the total radiation energy of the radiation T E at a level of between 8% and 35%.
- total energy of the radiation is meant here the solar radiation in the wavelength range between 250 nm and 2500 nm.
- a proportion of between 92% and 65% of the total energy of the radiation is therefore reflected (R E ) and / or absorbed (A E ), the ratio between the proportions R E and A E being determined by the nature and structure of the layer system.
- the total radiation passing through the window obviously also contains visible light in the wavelength range between 350 nm and 750 nm.
- the transmission T L in the visible range is between 5% and 75%.
- the individual panes of the laminated pane according to the invention may have different hues or absorption capacities to obtain defined effects such as total light transparency or perceived color through the pane.
- the outer pane may be less tinted than the inner pane to increase the effect of the layer system in terms of blocking the infrared radiation and at the same time obtain a defined overall tint or overall absorption of the laminated pane using a tinted glass inner glass more strongly.
- the layer system may be installed on the outer pane, on the inner pane or on the intermediate layer, provided it is disposed within the pane.
- a known thin-film system having one or more silver functional layers and appropriate layers of blocking and interference is preferred. These thin film systems are usually deposited on the support by vacuum coating (e.g., magnetron sputtering or PVD processes). The thickness of these individual layers as well as the coating materials used can be adapted to the particular case of use in a laminated pane according to the invention.
- the individual panes used in the laminated pane according to the invention can be made of glass, glass ceramic or a synthetic material, for example polycarbonate.
- the individual panes of the laminated pane according to the invention are preferably made of glass so as to form with the intermediate layer which connects the two panes a laminated glass safety glass.
- the panes will have a thickness of preferably between 1 mm and 5 mm.
- the windows will have to make it possible to reach a compromise as good as possible between a thin thickness and a good one. stability, especially when the laminated pane is mounted in an automobile. Such a compromise can be obtained with windows whose thickness is between 1.6 mm and 3.1 mm.
- polyvinyl butyral has proven to be a material that is suitable for the intermediate layer, and is used in most cases in thicknesses of 0.38 mm or 0.76 mm. mm.
- the total thickness of the laminated pane which presents the glass panes and the PVB as intermediate bonding layer is therefore in a preferred range of between about 3.6 mm and 7 mm.
- thermoplastics such as copolymers of ethylene and vinyl acetate (EVA), polyurethane (PU) or poly (vinyl chloride) (PVC). Casting resins can also be used to connect the individual panes.
- Tinted glass windows that absorb infrared radiation are known in different thicknesses of glass, depth of hue and colors.
- the Applicant proposes for example under the names SGS THERMOCONTROL ® Venus Green, SGS THERMOCONTROL ® Venus Gray and SGS THERMOCONTROL ® Absorbing TSA3 + glasses tinted green or gray in the mass, at different depths of hue and thicknesses that allow to obtain different transmission values.
- SGS designates Saint-Gobain Sekurit.
- a carrier sheet of polyethylene terephthalate (PET) has proven to be well suited, and is incorporated between two sheets of PVB after coating. In this way, a three-layer sheet is obtained which serves as an intermediate layer for connecting the individual panes into a laminated pane.
- thin film systems based on other materials, for example based on metal oxides, are also known. for example tin oxide doped with indium.
- Such a thin film system is also basically suitable for use in a laminated pane according to the invention.
- thin reflective and / or absorptive thin film systems still exist which do not contain electrically conductive functional layers but which individually form an interference layer system by means of a plurality of individual layers which have different refractive indices.
- 3M offers a sheet with such a layer system as the 3M TM Solar Reflecting Film (SRF).
- the laminated pane according to the invention reflects up to 50% of the visible radiation incident on the outer side by appropriate selection of the system of layers and windows used. From the outside, the laminated glass has the appearance of a mirror (partial). If necessary, the reflective colors of the layer system used can be modified or attenuated by tinting the outer glass pane. This is particularly useful when certain color effects are not desired or the external appearance hinders the association with other neighboring components.
- the intermediate layer may also have a clean hue and / or have an effect of absorption of infrared radiation.
- the intermediate layer When the intermediate layer must enhance the absorption effect of the infrared radiation of the outer pane, it must obviously be arranged in front of the layer system when viewed from the outside. It is only in this succession that the reflection colors of the intermediate layer can be further modified and that we can act on them.
- laminated glass according to the invention generally has a high selectivity.
- the selectivity is defined by a ratio between the transmitted light T L and the transmitted energy T E (T L / T E ), greater than 1.8.
- a selectivity greater than 2.4 will be established.
- the layer system will be preferably thermally stable so that a flat glass pane can first be provided with the layer system and then bent and / or preloaded
- the laminated pane according to the invention is suitable for use in roof windows, side windows or rear windows of vehicles.
- these windows are used as side windows from column B, the legal requirement which imposes a minimum transmission of 75% in the visible wavelength range is indeed not applicable, at least in Germany.
- the appearance of the light transmission of the windows is secondary and the priority is that the laminated pane gives an increased sensation of thermal comfort and a certain brightness inside the vehicle, the increased thermal comfort being obtained by means of a high selectivity in terms of light transmission and energy transmission.
- Table 1 shows the structure of the layer system used in the laminated panes tested in the comparative example and the two embodiment examples 1 and 2.
- the layer systems which all have two functional layers of silver, are deposited using a vacuum deposition method on the inner surfaces of the individual panes of the laminated panes.
- the lining of the inner pane is usual, because thus a border layer possibly necessary to prevent corrosion can be masked from the outside by means of an opaque edge coating installed on the inner surface of the pane. exterior.
- the edge coating is generally made of a printed ceramic color and then fired.
- the layers can obviously also be installed on the inner surface of the outer pane.
- Table 1 Structure of layers and glasses used for laminated glass
- Table 3 Optical properties of laminated glasses
- the laminated windows of the exemplary embodiments have a selectivity T L / T E significantly higher than the laminated pane of the comparative example.
- the laminated glass of the comparative example is used mainly as sun protection glazing in automobile windshields, and for this reason, the value of the light transmission T L must be set at 75% in order to comply with the legal requirements.
- absorbent windows are used which allow to bring the selectivity to values significantly higher than that of 1.7 of the comparative example by means of thin films adapted.
- the laminated panes according to the invention can not be used as windscreen panes, but are exceptionally well suited as panes of glass. roof or as windows for what is called “dark tail", ie applications in which the total energy of the radiation is reduced while allowing a certain amount of light to pass through.
- the laminated glass according to the invention is therefore particularly suitable as solar glazing and / or glazing protection and screen.
- the layer system makes the laminated pane reflective enough. But if we combine the system of reflective layers with absorbent outer glass panes, the laminated glass appears quite absorbent.
- the absorption of light by the outer glass makes it possible to reduce the reflection of light.
- a layer system consisting of two silver functional layers separated from one another by a dielectric is used as has already been indicated.
- Other dielectric layers are installed between the glass and the lower layer of silver and above the upper layer of silver. Thanks to these dielectric layers, on the one hand the layer system can, among other things, partly provide an antireflective effect by virtue of interference effects and, on the other hand, it is possible to act on the reflection and transmission colors.
- layer systems which have more than two functional layers.
- the largest number of dielectric interlayers also offers more opportunities for action to create as many layers as reflective • antireflective layers.
- it opens the possibility of adapting the color of the diaper system to the wishes of the customer. Frequently, it is desired in reflection a neutral blue or gray color.
- FIGS. 1 to 3 show, by way of example, the evolution of the percentage transmission of radiation as a function of wavelength for certain individual panes used in laminated glasses, namely for SGS PLANILUX ® , SGS THERMOCONTROL ® Absorbing TSA3 + and SGS THERMOCONTROL ® Venus Gray 10 (VG10), each for glass with a thickness of 2.1 mm.
- Figures 4.1 and 4.2 show the evolution of the radiation transmission and the reflection of the radiation as a percentage as a function of the wavelength, for the comparative example.
- the transmission and percentage reflectance values are shown for the embodiment example 1, and in FIGS. 6.1 and 6.2 for the exemplary embodiment 2.
- FIGS. 4 to 6 which show the optical values for the overall systems of the laminated panes
- the transmission is lower than in the comparative example, especially in the near infrared radiation spectrum.
- the transmission is also less, but, as already indicated, it does not matter for the preferred application.
- said reduced transmission of the visible light of the screen glass or protection against the view is even desirable.
- the embodiment example 1 Compared to the comparative example, the embodiment example 1 has both a lower transmission and a lower reflection in the visible area of the spectrum and thus obtains a laminated pane with absorption action and dark appearance.
- the figures of the embodiment 2 show that in the visible range of the spectrum, the reflection is relatively high.
- the laminated pane of the embodiment 2 has the appearance of a laminated glass pane that reflects in the visible range.
- the two exemplary embodiments apparently have very different effects, they still have a high selectivity T L / T E of 2.3 and 2.8, respectively.
- the laminated panes according to the invention make it possible to act in a controlled manner on the appearance of the laminated panes without subtracting from the desired high selectivity.
