Description

Technical Field

[0001] This utility model relates to the field of glass products, specifically to a coated laminated glass. Background Technology

[0002] Low-emissivity glass, also known as low-emissivity glass, is a product with multiple layers of metal or other compound coatings on its surface. Depending on the coating, it has advantages in many aspects, such as heat control, cooling costs, and a comfortable balance of internal sunlight projection.

[0003] As shown in Chinese patent application CN 112159116 A, a neutral gray temperable double silver LOWE coated glass includes a glass substrate layer and a coating layer. Fourteen coating layers are sequentially deposited on the surface of the glass substrate using a vacuum magnetron sputtering method. The first coating layer is a ZTO coating layer, the second coating layer is an AZO coating layer, the third coating layer is a Ti coating layer, the fourth coating layer is an Ag coating layer, the fifth coating layer is a Ti coating layer, the sixth coating layer is an AZO coating layer, the seventh coating layer is a ZTO coating layer, the eighth coating layer is an AZO coating layer, the ninth coating layer is a Ti coating layer, the tenth coating layer is an Ag coating layer, the eleventh coating layer is a Ti coating layer, the twelfth coating layer is an AZO coating layer, the thirteenth coating layer is a ZTO coating layer, and the fourteenth coating layer is a ZrO2 coating layer.

[0004] The above describes the basic structure of current LOWE products. However, the edge sealing of this structure relies on sealant for the protection of the film layer. The edge sealing is prone to delamination due to long-term thermal expansion and contraction, leading to problems such as water seepage and oxidation. The silver layer is quite sensitive to moisture, and if the edges are not completely sealed, they are easily corroded, resulting in increased emissivity and affecting service life. Furthermore, in the above technical solutions, a single glass substrate layer needs to be repeatedly coated more than ten times on the same side, which places high demands on the production process. If a problem occurs in one step, corresponding waste products will be generated and rework will be required, which is not conducive to production. Utility Model Content

[0005] Therefore, this utility model provides a coated laminated glass that solves the problem of unstable structure of coated laminated glass.

[0006] To achieve the above objectives, this utility model is implemented through the following technical solution:

[0007] A coated laminated glass includes a left glass substrate, a right glass substrate, and a composite frame covering both. The composite frame includes an adhesive sealing structure that adheres to the left and right glass substrates, and a titanium-aluminum alloy frame disposed outside the adhesive sealing structure. The titanium-aluminum alloy frame extends between the left and right glass substrates to form a hollow cavity between them. The left and right glass substrates on both sides of the hollow cavity are respectively provided with a left coating layer and a right coating layer.

[0008] Preferably, a rectangular groove is provided on the titanium-aluminum alloy frame located outside the hollow cavity, and the rectangular groove is filled with a moisture-proof filling layer, which is a silicon-based elastomer containing nano-SiO2 particles.

[0009] Preferably, the outer surface of the moisture-proof filling layer has an arc-shaped surface structure.

[0010] Preferably, the left coating layer and the right coating layer have the same structure.

[0011] Preferably, the left coating layer and / or the right coating layer each include a bottom oxide layer, an Ag film layer, and a top oxide layer stacked together.

[0012] Preferably, the colloidal sealing structure includes a butyl rubber layer in contact with the inner side, a polysulfide rubber layer disposed outside the butyl rubber layer, and a molecular sieve desiccant layer in contact with the titanium-aluminum alloy frame. The butyl rubber layer covers the edges of the left and right glass substrates and contacts the left and right coating layers to support the formation of the hollow cavity.

[0013] By adopting the aforementioned technical solution, the beneficial effects of this utility model are:

[0014] This technical solution differs from traditional multi-functional structural coating designs. Instead, it distributes the original multiple coating structures onto independent left and right glass substrates, supported by a specially structured composite frame. This disperses the original multi-layered coatings across different substrates, significantly reducing the demands on the production process and avoiding rework issues caused by problems during individual coating application. This greatly improves production efficiency, reduces material waste during rework, and saves on material and other production costs. Structurally, the titanium-aluminum alloy frame provides sufficient rigidity for the entire glass product, ensuring adequate structural dimensions of the hollow cavity. The resulting product not only possesses the traditional functions of insulated glass, such as improved sound insulation, heat insulation, and anti-condensation, but also retains the functionality of multi-layered coated glass, making it suitable for various applications.

Detailed Implementation

[0018] The following will describe the implementation of this utility model in detail with reference to specific embodiments, so that the process of how this utility model uses technical means to solve technical problems and achieve technical effects can be fully understood and implemented accordingly.

[0019] Example

[0020] refer to Figure 1 and Figure 2 A coated laminated glass includes a left glass substrate 1, a right glass substrate 2, and a composite frame covering both. The composite frame includes an adhesive sealing structure 3 that adheres to the left glass substrate 1 and the right glass substrate 2, and a titanium-aluminum alloy frame 4 disposed outside the adhesive sealing structure 3. The titanium-aluminum alloy frame 4 extends between the left glass substrate 1 and the right glass substrate 2 to form a hollow cavity a between them. The left glass substrate 1 and the right glass substrate 2 on both sides of the hollow cavity a are respectively provided with a left coating layer 11 and a right coating layer 21. Specifically, the colloidal sealing structure 3 includes a butyl rubber layer 31 contacting the inner side, a polysulfide rubber layer 32 disposed outside the butyl rubber layer 31, and a molecular sieve desiccant layer 33 in contact with the titanium-aluminum alloy frame 4. The butyl rubber layer 31 covers the edges of the left glass substrate 1 and the right glass substrate 2, and contacts the left coating layer 11 and the right coating layer 21 to support and form the hollow cavity a. That is, the titanium-aluminum alloy frame 4 has a protrusion 41 extending between the left glass substrate 1 and the right glass substrate 2. The surface of the protrusion 41 has the butyl rubber layer 31 and contacts the two glass substrates, thereby fixing and supporting the formation of the hollow cavity a. The butyl rubber layer 31 is in direct contact with the glass surface and edges, with a thickness of 0.4 mm, fixing the structure and blocking moisture. The polysulfide rubber layer 32 has a thickness of 2 mm, providing mechanical strength. The molecular sieve desiccant layer 33 is pre-embedded in the titanium-aluminum alloy frame 4 during production, enabling the product to dynamically adsorb residual moisture.

[0021] Both the left glass substrate 1 and the right glass substrate 2 are made of float glass, and their thickness can be selected according to the coating material and number of layers chosen for the left coating layer 11 and the right coating layer 21, ranging from 3 to 19 mm. The left coating layer 11 and the right coating layer 21 can have the same structure or different coating structures. Taking LOWE coating as an example, the right coating layer 21 or (or the left coating layer 11) includes a bottom oxide layer 211, an Ag film layer 212, and a top oxide layer 213 stacked together. The bottom oxide layer 211 can be TiO2 or ZnO, used to enhance the adhesion of the silver layer. The process involves focusing on and adjusting the color of light reflection. The Ag film layer 212 is the core functional layer, with a thickness of approximately 6-15 nm. It reflects far-infrared rays through free electrons, reducing emissivity. The top oxide layer 213 can be SnO2 or SiNx. Functionally, it protects the silver layer from oxidation while regulating transmittance and reflectivity. Incorporating fluorine (FTO) into the top oxide layer reduces visible light reflection loss by approximately 2-3%, and the transmittance can be increased to over 85%. When producing higher-end products, an anti-reflection coating such as SiO2 can be added to the outermost layer to further reduce visible light reflection loss. This technical solution differs from traditional multi-functional structural coating designs. Instead, it distributes the original multiple coating structures onto independent left and right glass substrates 1 and 2, respectively, and then uses a specially structured composite frame for structural support. This disperses the original multi-layered coatings across different substrates, significantly reducing the requirements for the production process and avoiding rework issues caused by problems during the application of individual coatings. This greatly improves production efficiency, reduces material waste during rework, and saves on material and other production costs. Structurally, the titanium-aluminum alloy frame 4 provides sufficient rigidity support for the entire glass product, ensuring the structural dimensions of the hollow cavity a. The resulting product not only possesses the traditional functions of insulated glass, such as improved sound insulation, heat insulation, and anti-condensation, but also retains the functionality of multi-layered coated glass, making it suitable for various applications.

[0022] Structurally, a rectangular groove 42 is provided on the titanium-aluminum alloy frame 4 located outside the hollow cavity a (i.e., outside the protrusion 41). The rectangular groove 42 is filled with a moisture-proof filling layer 43. The moisture-proof filling layer 43 is a silicon-based elastomer containing nano-SiO2 particles, which has both sealing and stress buffering functions, and can compensate for the temperature difference deformation between the glass and the metal frame, reducing the stress concentration at the interface. Furthermore, the outer surface of the moisture-proof filling layer 43 has an arc-shaped structure, forming an arc surface centered on the protrusion 41. The thickness of the moisture-proof filling layer 43 is greatest at the position of the protrusion 41, thus providing better elastic support for the hollow cavity a and ensuring structural stability.
