Description

TECHNICAL FIELD

[0001] The present invention relates to a high-strength glazing and a method usable for the production of such a glazing, in particular as a transparent marine window, but also as a building glazing or a window for ground or air transportation vehicles. BACKGROUND

[0002] Considering for example a marine window, high loads generated by waves or gusts or gales impacting on the marine window can lead to high mechanical loads and even very high loads of the marine window, resulting in a possible damage and even breakage of the window or glazing and thus possibly in a danger for the passengers and crew inside the ship. Similar considerations apply to high-strength glazings used in buildings or ground and air transportation vehicles. SUMMARY

[0003] It is therefore an object of the present invention to provide a high-strength glazing which exhibits a reduced likelihood of damage even under high mechanical load conditions.

[0004] This object is solved by the high-strength glazing or window as set forth in the present invention. Thus, the high-strength glazing, in particular for marine windows, comprises at least an outer high-strength glass layer and an inner high-strength glass layer in the form of a laminate and comprises a delaminating functional block arranged and integrated between the outer high-strength glass layer and the inner high-strength glass layer in the laminate.

[0005] The glazing of the present invention provides a significant advantage in that the functional block is itself protected from too strong mechanical pressure due to the arrangement of the functional block in the position between the high-strength glass layers or glass panes. Thus, the present invention enables the functional block to have a long-lasting durability without damage, such as for example a crack in the functional block, and thus also the entire laminate of the glazing.

[0006] The "high-strength glass layer" of the present invention preferably exhibits a strengthened glass with a fracture strength in the range of about 160 MPa to 400 MPa. This means that the allowable mechanical stress of the high-strength glass layer is about 40 MPa to 100 MPa for a short load period. The strengthened glass preferably corresponds to a tempered or strengthened or safety glass which has been strengthened in its strength (compared to a float glass or annealed glass) by a controlled thermal or chemical treatment.

[0007] The delaminating functional block provides additional functionality to the glazing, mainly but not limited to solar protection, for example, a switchable light transmission of the glazing, an electronic circuit layer or an antenna layer, etc.

[0008] The layered functional block preferably comprises a layered solar protection device arranged and integrated between the outer high-strength glass layer and the inner high-strength glass layer in the laminate, wherein the layered solar protection device preferably suppresses UV (ultraviolet) and / or IR (infrared) solar radiation by, but not limited to, reflection. In this embodiment of the present invention, the layered solar protection device is protected itself from excessive, not allowed mechanical stresses, as it is located between the high-strength glass layers. Thus, the present invention enables a long-lasting durability of the solar protection without damage, such as e.g. cracks in the structure of the solar protection, thus resulting in a long-lasting durability of the entire laminate of high-strength glazing.

[0009] Preferably, the glazing comprises a neutral line or layer extending inside, adjacent to or close to the layered functional block or solar protection device to avoid excessive, not allowed mechanical stresses to the functional block or solar protection layer of the present invention. By "neutral line or layer" is meant a line or neutral layer of the cross-sectional area of the glazing which exhibits a mechanical stress close to zero or at most the allowable mechanical stress, if the glazing is subjected to a mechanical load from the outside. The neutral line or layer of the glazing extends through the center or main focus of the cross-sectional area of the unloaded glazing.

[0010] The functional block or the layered solar protection device can be positioned in the glazing of the present invention such that the mechanical stress resulting from an outside bending load acting on the outer high-strength glass layer is not higher than the allowable bending tensile stress of the functional block or the layered solar protection device, thereby avoiding damage of the functional block or the layered solar protection device.

[0011] The layered functional block can comprise at least one annealed glass pane. Preferably, the annealed glass pane is positioned in the glazing such that the mechanical stress resulting from an outside bending load acting on the outer high-strength glass layer is not higher than the allowable bending tensile stress of the annealed glass pane. The annealed glass pane can extend on, along or parallel to the neutral line or neutral layer of the glazing.

[0012] The layered solar protection device preferably comprises at least one annealed glass pane and a solar protection layer provided on the annealed glass pane, wherein the annealed glass pane is positioned in the glazing such that the mechanical stress resulting from an outside bending load acting on the outer high-strength glass layer is not higher than the allowable bending tensile stress of the annealed glass pane, wherein the annealed glass pane extends on, along or parallel to the neutral line or neutral area of the glazing.

[0013] The middle portion of the cross-sectional area of the insulating glass unit near the neutral line or neutral layer of the insulating glass unit is usually in slight compression or at most under slight tension.

[0014] According to the present invention, the optimal location of the annealed glass pane with only small stresses or minimal stresses is exactly near the neutral line or neutral layer towards the side of the outer high-strength glass layer of the insulating glass unit. The present invention incorporates this functional block or solar protection element into the cross-section of the structural insulating glass unit, positioning the functional block or solar protection element adjacent to or near or next to the neutral layer of the insulating glass unit.

[0015] Annealed glass, which can also be referred to as non-strengthened glass or float glass, usually shows a breaking strength in the range of 40 MPa to 70 MPa. This means that the permissible mechanical stress of an annealed glass pane in the short loading period is in the range of 10 MPa to 18 MPa.

[0016] Preferably, the layered solar protection device comprises one or more interlayers with a high modulus of elasticity, thereby reducing the likelihood of excessive tensile stresses in the annealed glass pane.

[0017] The layered solar protection device of the present invention preferably comprises an annealed glass pane and a solar protection layer for suppressing UV (ultraviolet) and / or IR (infrared) solar radiation, wherein the solar protection layer is arranged between the outer high-strength glass layer and the annealed glass pane. The solar protection layer can comprise a thin metal layer, which can be selected from the group comprising silver, gold, copper, aluminum and combinations thereof. Preferably, the thin metal layer is made of one or more silver coatings. The layered solar protection device of the present invention can comprise a solar protection layer made by a sputtering process and incorporating a single silver coating or a multiple silver coating, wherein a three-silver coating shows almost perfect reflectivity in the IR or NIR and / or UV solar regions and almost perfect transmissivity in the visible light region.

[0018] Advantageously, using an industrial sputtering process, the silver coating as solar protection layer can be sputtered or deposited on the annealed glass pane, resulting in e.g. a double silver layer, a triple silver layer and a quadruple silver layer, which show almost perfect properties of almost complete transmission in the visible light portion of the solar wavelength spectrum of 380 nm to 780 nm and almost complete reflection in the UV portion of the solar wavelength spectrum of 300 nm to 380 nm and in the NIR portion of 780 nm to 2500 nm. In particular, a three-silver coating shows almost perfect reflectivity in the UV and / or IR or NIR solar regions and almost perfect transmissivity in the visible light region.

[0019] The high-strength glass layers of the present invention can be made of glass chemically strengthened by ion exchange, or the high-strength glass layers can be made of heat-strengthened glass. In another alternative, the high-strength glass layers can be chemically strengthened by ion exchange and the high-strength glass layers can be heat-strengthened, or one of the high-strength glass layers can be chemically strengthened by ion exchange and another one of the high-strength glass layers can be heat-strengthened. Thus, the present invention can encompass a wide range of different mechanical load cases or applications.

[0020] The layered solar protection device can comprise an annealed glass pane and comprise a solar protection layer consisting of a physical or chemical vapor deposition coating located on the annealed glass pane.

[0021] The layered solar protection device can be made by a sputtering process to produce a transparent conductive layer, a reflective layer, or an anti-reflective or absorbing layer. The layered solar protection device can be made by a chemical process to produce a transparent conductive layer, a reflective layer, or an anti-reflective or absorbing layer. The layered functional block or the layered solar protection device can comprise a sputtered or deposited top interference protection layer, a sputtered or deposited barrier layer, a sputtered or deposited silver coating or layer, a sputtered or deposited seed layer, a sputtered or deposited interference base layer, and an annealed glass pane as a substrate of the thin film system.

[0022] The inner high-strength glass layer and the outer high-strength glass layer of the present invention can be arranged in a tensile portion of the glazing or in the cross-section of the glazing when the glazing is subjected to bending loads, thereby excluding or reducing tensile stresses from the solar protection layer device.

[0023] Preferably, the inner high-strength glass layer and the outer high-strength glass layer are arranged in the glazing or in the cross-sectional area of the glazing at a position where the stresses are below the allowable value.

[0024] The present invention also relates to a method of producing a high-strength glazing, comprising the following steps:

[0025] providing at least one outer high-strength glass layer and one inner high-strength glass layer, and a layered functional block or a layered solar protection device;

[0026] arranging the layered functional block or the layered solar protection device between the outer high-strength glass layer and the inner high-strength glass layer to obtain a pre-fabricated glazing stack; and thereafter

[0027] treating the pre-fabricated glazing stack in an autoclave to laminate the pre-fabricated glazing stack, thereby obtaining a high-strength glazing. BRIEF DESCRIPTION OF DRAWINGS

[0033] Figure 1 A schematic cross-sectional view of a high-strength glazing 1 according to a first preferred embodiment of the present application is shown. The high-strength glazing 1 has as a functional block a layered solar protection device 2. The high-strength glazing 1 is transparent to visible light. The high-strength glazing can have dimensions of about 3000 mm x 2000 mm, but is not limited thereto.

[0034] The high-strength glazing 1 or window, which can be used as a marine window in a marine vessel, comprises an outer high-strength glass layer 3, which faces towards the outside of the vehicle or marine vessel, an inner high-strength glass layer 4, which faces towards the inside of the vehicle, marine vessel or building in the form of a laminate, and a layered solar protection device 2 arranged and integrated between the outer high-strength glass layer and the inner high-strength glass layer 3 and 4 in the laminate.

[0035] The high-strength glass layers 3 and 4 of the present application preferably exhibit a breaking strength of about 240 MPa of strengthened glass. This means that the high-strength glass layers 3 and 4 each have an allowable mechanical stress of about 60 MPa over a short load period. The high-strength glass layers 3 and 4 are made of strengthened glass corresponding to tempered or strengthened glass or safety glass.

[0036] The layered solar protection device 2 comprises an outer adhesive layer 2.1 and an inner adhesive layer 2.2 and it inhibits UV (ultraviolet) and / or IR (infrared) solar radiation. The outer adhesive layer 2.1 is adjacent to the outer high-strength glass layer 3 and the inner adhesive layer 2.2 is adjacent to the inner high-strength glass layer 4. The outer and inner adhesive layers 2.1 and 2.2 can be made of PVB (polyvinyl butyral). The layered solar protection device 2 preferably comprises, but is not limited to, an annealed non-tempered glass pane coated with a functional solar protection film coating.

[0037] The high-strength glazing 1 comprises a neutral line or layer 5 that exhibits zero mechanical stress if the glazing 1 is subjected to loads from the outside. The neutral layer 5 extends inside or close to the layered solar protection device 2, thus avoiding excessive mechanical stress on the layered solar protection device 2.

[0038] Figure 2 A further schematic partial cross-sectional view of a high-strength glazing 1.1 according to another preferred embodiment of the present application is shown. The high-strength glazing 1.1 has a layered solar protection device 2.11 as a functional block.

[0039] The high-strength glazing 1.1 comprises an outer high-strength glass layer 3.1, an inner high-strength glass layer 4.1 in the form of a laminate, and the layered solar protection device 2.11 is arranged and integrated between the outer and inner high-strength glass layers 3.1 and 4.1 in the laminate.

[0040] The layered solar protection device 2.11 comprises an outer adhesive layer 2.12, an inner adhesive layer 2.13 and an annealed glass pane 2.19. The layered solar protection device 2.11 inhibits UV (ultraviolet) and / or IR (infrared) solar radiation. The high-strength glazing 1.1 likewise comprises a neutral line or layer 5.1 extending within the layered solar protection device 2.11. The outer adhesive layer 2.12 is adjacent to the outer high-strength glass layer 3.1 and the inner adhesive layer 2.13 is adjacent to the inner high-strength glass layer 4.1.

[0041] The outer and inner adhesive layers 2.12 and 2.13 can be made of PVB (polyvinyl butyral), preferably high modulus PVB, such as Eastman's Saflex® or Kuraray-Trosifol's Extra-Strong Another suitable material for the outer and inner adhesive layers 2.12 and 2.13 is an ionomer resin, such as Kuraray-Trosifol's Ionic interlayer. Other interlayers used in glass laminates are aliphatic thermoplastic polyurethane (TPU), although its elastic modulus is generally lower than that of structural PVB or ionomer interlayers. The optimal delamination section under external bending loads is obtained when the stress is uniformly transmitted through the various layers, and this is achieved when the shear modulus of the adhesive layers 2.12 and 2.13 is higher than > about 50 MPa. The thickness of the adhesive layers 2.12 and 2.13 can be comprised between 0.3 mm and 3 mm, preferably, the thickness is about 1.52 mm.

[0042] In Figure 2 In an embodiment of the application, the solar protection is based on a thin film system arranged or deposited on an annealed glass pane 2.19 as carrier or substrate, having a thickness comprised between about 2 mm and 6 mm, preferably 4 mm.

[0043] The solar protection function is achieved by reflecting the near-infrared portion of the solar radiation wavelengths comprised between 780 nm and 2500 nm by a silver layer 2.16 as solar protection layer, having a thickness comprised between 10 nm and 20 nm, preferably 15 nm. In order to allow the transmission of the visible portion of the solar radiation with wavelengths comprised between 380 nm and 780 nm, the silver layer 2.16 is arranged between the top protection interference layer 2.14 and the interference base layer 2.18 in the thin film system.

[0044] Additionally, in order to allow the silver layer 2.16 to have the best nucleation phenomenon and to protect it from chemical reactions that can cause corrosion and degradation, the silver layer 2.16 is deposited on a seed layer 2.17 made of ZnO, for example, having a thickness less than < 15 nm. Preferably, the thickness of the seed layer 2.17 is 10 nm. Furthermore, the silver layer 2.16 is protected by a barrier layer 2.15 made of a metal or a sub-valent metal oxide, preferably NiCr or NiCrOx, and having a thickness comprised between 2 nm and 8 nm, preferably 5 nm.

[0045] The delaminated solar protection device 2 comprises, in the order shown, between the external and internal adhesive layers 2.12 and 2.13, the following layers and coatings:

[0046] - a top protection interference layer 2.14 made of Si3N4, for example, having a thickness of about 2 nm to 20 nm, preferably about 11 nm, and / or of ZnO having a thickness comprised between 30 nm and 70 nm, preferably 50 nm;

[0047] - a sputtered barrier layer 2.15 made of NiCr or NiCrOx, having a thickness of about 2 nm to 6 nm, preferably 4 nm;

[0048] - a sputtered silver coating or layer 2.16 having a thickness of between about 12 nm to 15 nm, preferably 13.5 nm;

[0049] - a seed layer 2.17, for example made of ZnO or ZnO:SnO2:Al2O3, having a thickness of about 3 nm to 10 nm, preferably 6.5 nm;

[0050] - an interference / base layer 2.18, for example made of zinc stannate ZTO or SnO2, having a thickness of between about 30 nm to 80 nm, preferably about 55 nm; and

[0051] - an annealed glass pane 2.19 adjacent to the inner adhesive layer 2.13.

[0052] The transparent annealed glass pane 2.19 corresponds to annealed non-tempered glass or float glass and preferably shows a breaking strength of about 70 MPa. This means that the annealed glass pane 2.19 has an allowable mechanical stress of about 17.5 MPa for a short load period. The annealed glass pane 2.19 is adjacent to the neutral layer 5.1 of the high-strength glazing 1.1.

[0053] The outer and inner adhesive layers 2.12 and 2.13 exhibit a higher modulus of elasticity, which leads to a value of the shear modulus of about 50 MPa to reduce the likelihood of excessive tensile stresses in the annealed glass pane 2.19 that can be higher than > about 17.5 MPa.

[0054] The sputtered silver coating 2.16 is a near-ideal solar protection layer that is almost completely transmissive in the visible part of the solar wavelength spectrum of 380 nm to 780 nm and almost completely reflective in the UV part of the solar spectrum of 300 nm to 380 nm and in the IR part of 780 nm to 2500 nm.

[0055] The high-strength glazing 1.1 can be prepared by providing an outer high-strength glass layer 3.1 and an inner high-strength glass layer 4.1 and the layered solar protection device 2.11 between the outer and inner high-strength glass layers 3.1 and 4.1 to obtain a pre-glazing stack.

[0056] The thin-film system of the layered solar protection device 2.11 can be provided and prepared step by step in the following way:

[0057] - depositing the interference / base layer 2.18 on the annealed glass pane 2.19 by sputtering or chemical vapor deposition;

[0058] - then a seed layer 2.17 or coating is deposited by sputtering or chemical vapor deposition on the interference base layer 2.18;

[0059] - at this point, a silver coating 2.16 is sputtered or deposited onto the seed layer 2.17;

[0060] - thereafter, a barrier or absorption layer 2.15 or coating is sputtered or deposited on the silver coating 2.16;

[0061] - then, an interference top layer 2.14 is deposited or sputtered on the barrier layer 2.15.

[0062] The thus obtained thin film system is arranged between an outer and an inner adhesive layer 2.12 and 2.13 of high modulus polymer to obtain a layered solar protection device 2.11 which is assembled between an outer and an inner high strength glass pane 3.1 and 4.1 to provide a pre-assembled glazing stack.

[0063] Finally, the pre-assembled glazing stack is treated in an autoclave to laminate the pre-assembled glazing stack, thereby achieving sufficient adhesion between the layers and obtaining a complete layered high strength glass 1.1.
