Description

Technical Field

[0001] The present invention belongs to the field of glass, and particularly relates to a bent tempered triple-silver glass and a preparation method thereof, and a flat-bent integrated triple-silver laminated insulating glass. Background Art

[0002] Triple-silver glass is a coated glass with a multi-layer composite film structure, and the coating contains three independent silver layers, having good energy-saving effects. With the in-depth global consensus on carbon neutrality, the demand for low-carbon and high-energy-saving products globally has gradually formed a new trend. Therefore, the curtain wall designs in major cities around the world prefer more energy-saving double-silver / triple-silver glass products. To show the originality of their designs, the shapes of the exterior wall energy-saving glass products designed are becoming more and more unique. Some key projects are often designed with a flowing or curved appearance to reflect the personalized differences in their design appearances and convey their relevant design concepts. To increase safety, laminated coated products are used, so there are many flat-bent coated laminated products, and some curved products involve single-curved and double-curved coated laminated products. Under the existing technical conditions, the flat-bent matching effect of high-performance double-silver and triple-silver coated products is not ideal, and the triple-silver matching effect is even worse. Most of them have obvious color differences such as small angles outdoors, reflected colors indoors, and transmitted colors that are visible to the naked eye.

[0003] To reduce this difference, usually the following two methods are adopted:

[0004] First, for the same process, that is, using the same film of a temperable film system. For example, a triple-silver product uses a temperable triple-silver film to achieve the same color. However, in actual applications, there are often deformation problems after tempering the temperable triple-silver. The deformation is inconsistent with that of the uncoated laminated white glass when paired, and there are often quality problems such as delamination and bubbles after lamination. The solution often adopts a vacuum pumping process, but this production efficiency is very low and the manufacturing cost is very high, and it is only applied to bent tempered products that have to use vacuum pumping.

[0005] Second, for different processes, such as matching triple-silver flat products, the energy-saving requirements are often reduced for curved products, and single-silver or double-silver products are used to match the flat triple-silver. Although the difference is improved when observed outdoors and the production and processing difficulty is reduced, the energy-saving performance is significantly reduced, which does not meet the energy-saving requirements.

[0006] At present, for temperable triple-silver insulating glass products, the relatively mature domestic matching products are mainly in the high-transmittance region (the region where the visible light transmittance of the insulating glass ≥ 60%), and their processing wear resistance is not good, posing a great quality risk for subsequent tempering, heat soaking, and lamination. In the medium and low transmittance region (the region where the visible light transmittance of the insulating glass is 40 - 55%), due to poor matching, it is often impossible to be effectively applied. Summary of the Invention

[0007] The present invention aims to solve at least one of the technical problems existing in the above-mentioned prior art. For this purpose, the present invention provides a bent tempered triple-silver glass, a preparation method thereof, and a flat-curved integrated triple-silver laminated insulating glass. The second dielectric composite layer and the third dielectric composite layer of the bent tempered triple-silver glass are pure oxide layers, which can effectively solve the problem of poor wear resistance after tempering; the bent tempered triple-silver glass is paired with a flat tempered triple-silver glass to form a flat-curved integrated triple-silver laminated insulating glass that is extremely matched in terms of performance and color.

[0008] To solve the above technical problems, a first aspect of the present invention provides a bent tempered triple-silver glass, which includes a first glass substrate and a bent tempered coating layer, and the bent tempered coating layer is compounded on the surface of the first glass substrate;

[0009] The bent tempered coating layer sequentially includes a first dielectric composite layer, a first Ag protection layer, a first Ag layer, a second Ag protection layer, a first crystal bed dielectric layer, a second dielectric composite layer, a second Ag layer, a third Ag protection layer, a second crystal bed dielectric layer, a third dielectric composite layer, a third Ag layer, a fourth Ag protection layer, a third crystal bed dielectric layer, and a fourth dielectric composite layer from inside to outside;

[0010] The second dielectric composite layer and the third dielectric composite layer are oxide composite layers, and the oxide composite layer is at least two of a ZnSnO layer, a ZnAlO layer, and a composite layer of ZnSnO and ZnAlO.

[0011] Specifically, compared with the traditional bent tempered (non-planar tempered) triple-silver glass in which the intermediate dielectric layer contains a SiN layer, the intermediate dielectric layer (the second dielectric composite layer and the third dielectric composite layer) of the bent tempered triple-silver glass of the present invention adopts pure oxides, which can solve the problem of poor wear resistance after tempering. The main reason is that after tempering, recrystallization occurs between the nitride and the oxide, part of the oxygen enters the nitride, and part of the nitrogen enters the oxide, forming a nitride oxide with a higher roughness. The rougher it is, the greater the friction force, resulting in problems of poor wear resistance and easy film peeling.

[0012] Among them, the composite layer of ZnSnO and ZnAlO is arranged alternately with a ZnSnO layer and a ZnAlO layer.

[0013] As a further improvement of the above solution, the first dielectric composite layer is at least two of a SiZrN layer, a SiN layer, and a ZnAlO layer, and the innermost layer of the bent tempered coating layer is a SiZrN layer.

[0014] Specifically, to enhance the bonding force between the film layer and the glass substrate, the innermost layer of the film layer uses SiZrN similar to the main material of the glass for transition. Among them, Zr zirconium is easy to absorb hydrogen, nitrogen, and oxygen, and Zr has a strong affinity for oxygen. The glass to be coated is cleaned with high-purity water by a coating cleaning machine, and its surface often remains contaminated layers such as suction cup marks and foam strip marks that are difficult to see with the naked eye. After tempering, the oxygen in this part is likely to cross the dielectric underlayer and enter the internal metal Ag layer, forming oxidation of the Ag layer, and the appearance defects of the tempered glass thus appear. Since the affinity of zirconium for oxygen is very strong, when the innermost layer uses SiZrN, this part of oxygen can be absorbed during the tempering heating, thereby eliminating the product defects caused by the unclean glass surface after tempering.

[0015] As a further improvement of the above solution, the fourth dielectric composite layer is a nitride layer or an oxide layer, and the outermost layer of the bent steel coating layer is an oxide layer; the nitride layer is a SiZrN layer and / or a SiN layer, and the oxide layer is a SiZrO layer and / or a ZrO layer.

[0016] Specifically, setting the outermost layer as an oxide layer is beneficial to the subsequent processing requirements of the visible steel triple silver film, such as cutting, grinding, tempering, laminating, and insulating, etc., and is also beneficial to improving the oxidation resistance, scratch resistance, etc. of the glass.

[0017] Among them, when the nitride layer is a SiZrN layer and a SiN layer, the SiZrN layer and the SiN layer are alternately arranged; when the oxide layer is a SiZrO layer and a ZrO layer, the SiZrO layer and the ZrO layer are alternately arranged.

[0018] As a further improvement of the above solution, the first Ag protection layer, the second Ag protection layer, the third Ag protection layer, and the fourth Ag protection layer are all Ti layers and / or NiCr layers.

[0019] As a further improvement of the above solution, the first crystal bed dielectric layer, the second crystal bed dielectric layer, and the third crystal bed dielectric layer are all AZO layers.

[0020] Preferably, the thickness of the first dielectric composite layer is 20 - 50 nm.

[0021] Preferably, the thickness of the second dielectric composite layer is 40 - 70 nm.

[0022] Preferably, the thickness of the third dielectric composite layer is 40 - 80 nm respectively.

[0023] Preferably, the thickness of the fourth dielectric composite layer is 15 - 55 nm.

[0024] Preferably, the thickness of the first Ag layer is 5 - 12 nm.

[0025] Preferably, the thicknesses of the second Ag layer and the third Ag layer are both 5 - 20 nm.

[0026] Preferably, the thicknesses of the first Ag protective layer and the second Ag protective layer are both 0.5 - 3 nm.

[0027] Preferably, the thicknesses of the third Ag protective layer and the fourth Ag protective layer are both 1 - 8 nm.

[0028] Preferably, the thicknesses of the first crystal bed dielectric layer, the second crystal bed dielectric layer, and the third crystal bed dielectric layer are all 5 - 20 nm.

[0031] As a further improvement of the above - mentioned solution, the film coating adopts a magnetron sputtering process, and the second dielectric combination layer and the third dielectric combination layer are sputtered with argon and oxygen.

[0032] Preferably, the target materials of the second dielectric combination layer and the third dielectric combination layer for sputtering are ZnSn and ZnAl, an AC rotating target is used, and the sputtering gas pressure is 3×10 -3 to 5×10 -3 mbar, and sputtering is performed with argon and oxygen.

[0035] Preferably, the target materials of the first Ag layer, the second Ag layer, and the third Ag layer are Ag. A DC planar target is used, and the sputtering pressure is 2×10 -3 to 3×10 -3 mbar, and argon is used for sputtering.

[0036] Preferably, the target materials of the first Ag protection layer, the second Ag protection layer, the third Ag protection layer, and the fourth Ag protection layer are NiCr and Ti. A DC planar target is used, and the sputtering pressure is 2×10 -3 to 3×10 -3 mbar, and argon is used for sputtering.

[0038] The third aspect of the present invention provides a flat-bending integrated triple-silver interlayer insulating glass, which includes flat-tempered (planar tempered) triple-silver glass and bent-tempered triple-silver glass. A hollow interlayer is provided between the flat-tempered triple-silver glass and the bent-tempered triple-silver glass, and the bent-tempered triple-silver glass is the above-mentioned bent-tempered triple-silver glass.

[0039] As a further improvement of the above solution, the flat-tempered triple-silver glass includes a second glass substrate and a flat-tempered coating layer, and the flat-tempered coating layer is compounded on the surface of the second glass substrate;

[0040] The flat-tempered coating layer sequentially includes multiple film layers from the inside to the outside, where: the innermost layer is the SiZrN layer, and the outermost layer is the SiZrO layer or the ZrO layer; the intermediate dielectric layer is a combined layer of nitride and oxide.

[0041] As a further improvement of the above solution, the flat-tempered coating layer sequentially includes the SiZrN layer, the ZnAlO layer, the Ag layer, the NiCr / Ti layer, the AZO layer, the SiZrN / SiNx layer, the ZnSnO / ZnAlO layer, the Ag layer, the NiCr / Ti layer, the AZO layer, the SiZrN / SiN layer, the ZnSnO / ZnAlO layer, the Ag layer, the NiCr / Ti layer, the AZO layer, the SiZrN / SiN layer, the ZrO / SiZrO layer; where the SiZrN / SiN layer represents the SiZrN layer and / or the SiN layer, the NiCr / Ti layer represents the NiCr layer and / or the Ti layer, and ZnSnO / ZnAlO represents the ZnSnO layer and / or the ZnAlO layer.

The flat steel coating layer is also coated by magnetron sputtering, and the coating process of each layer (including the corresponding target material, sputtering gas pressure, and sputtering gas) is basically the same as that of the bent steel coating layer described above. At the same time, the second glass substrate has the same material as the first glass substrate.
