Description

Technical Field

[0001] This invention relates to the field of laminated glass technology, and in particular to an aerogel laminated composite glass, a window, and a method for preparing the same. Background Technology

[0002] Aerogel laminated glass is a high-performance material that combines aerogel and glass layers. It is mainly used to improve thermal insulation and sound insulation. When integrated, aerogel is filled between two or more layers of glass. By utilizing the low thermal conductivity and excellent sound insulation properties of aerogel, thermal insulation and sound insulation effects are achieved. It is widely used in buildings, aerospace and high-end vehicles.

[0003] The existing invention patent application with publication number CN109963822A discloses an insulating sheet, an interlayer for laminated glass and laminated glass. The laminated glass includes an insulating sheet, and the insulating sheet includes an aerogel layer of aerogel and a resin layer containing thermoplastic resin laminated on at least one side of the aerogel layer.

[0004] In the above scheme, the aerogel layer and other layers adopt a stacked structure, but lack edge treatment; since aerogel is a porous structure, it may break under slight impact. It is a fragile material like glass, so it is prone to breakage during subsequent transportation and installation, affecting the structural stability.

[0005] Another utility model patent with authorization announcement number CN205046712U discloses a double-layer thermal insulation glass curtain wall, including an outer layer of glass, an inner layer of glass, a coating, and an aerogel layer. The coating is provided on one side of the outer layer of glass and on one side of the inner layer of glass. The aerogel layer is provided between the outer layer of glass and the inner layer of glass. The bolt is provided on one side of the concave base and the nut is provided on the other side of the concave base.

[0006] This technical solution mentions the fixing structure of aerogel laminated glass, which is to connect it to the concave base by passing bolts through the glass and aerogel layer. However, it is relatively difficult to open the glass, and if the bolts collide when they are tightened, the aerogel layer and glass are easily damaged. Therefore, it is urgent to improve the existing aerogel laminated glass structure. Summary of the Invention

[0007] In view of this, the present invention proposes an aerogel laminated composite glass and window, and a method for preparing the same, which can effectively protect the edges of the composite glass from damage and is convenient for transportation and installation, in order to solve the problems of inconvenient assembly and easy damage of existing aerogel laminated glass.

[0008] The technical solution of this invention is implemented as follows:

[0009] On one hand, the present invention provides an aerogel laminated composite glass, comprising an aerogel base layer, an adhesive layer, a glass layer, a flexible frame, and a locking element, wherein,

[0010] An adhesive layer is provided on both sides of the aerogel base layer;

[0011] The glass layer is bonded to the aerogel substrate through an adhesive layer, and the size of the glass layer is smaller than the size of the aerogel substrate;

[0012] The flexible frame covers the edges of the aerogel base layer, adhesive layer and glass layer, and the flexible frame partially penetrates the aerogel base layer;

[0013] The locking element extends through the flexible frame and is interference-fitted with the flexible frame to tighten and lock the aerogel base layer to the flexible frame.

[0014] Based on the above technical solutions, preferably, the flexible frame includes a planar portion, corner portions, and through portions of an integrated structure, wherein the aerogel base layer protrudes from the glass layer, and the protruding portion has through holes, wherein...

[0015] The flat portion is bonded to the part of the aerogel base layer that protrudes from the glass layer;

[0016] The corners of the adhesive layer and the glass layer are bonded together, as well as the side of the glass layer away from the adhesive layer;

[0017] The planar portion and corner portion are provided on both sides of the aerogel base layer;

[0018] The through-hole is penetrating the part, and the end of the through-hole is connected to the flat parts on both sides of the aerogel base layer.

[0019] Based on the above technical solutions, preferably, a rigid frame is also included, which is set on the surface of the flexible frame away from the aerogel base layer and the glass layer.

[0020] The locking element runs through the rigid frame.

[0021] Based on the above technical solutions, preferably, the locking component includes a rod and a protrusion, wherein,

[0022] The pole extends through both the flexible and rigid frames;

[0023] There are two protrusions on the rod, and the protrusions correspond to the glass layer.

[0024] Based on the above technical solutions, preferably, the rod portion includes an elastic portion and a rigid portion, wherein,

[0025] There are two elastic parts arranged opposite each other, and the two elastic parts are connected by a rigid part, and the elastic parts correspond to the rigid frame;

[0026] The rigid part corresponds to the flexible frame, and the protrusion and the rigid part are set as an integral structure.

[0027] Based on the above technical solutions, preferably, it also includes a set screw, which passes through the elastic part and is connected to the rigid part through a threaded engagement;

[0028] The head of the set screw is recessed into the elastic part to expand the elastic part.

[0029] On the other hand, the present invention provides a window comprising the aforementioned aerogel laminated composite glass, and further comprising a composite frame surrounding the aerogel laminated composite glass and supporting a flexible frame and a rigid frame.

[0030] Based on the above technical solutions, preferably, the composite frame includes multiple interconnected frame borders, each frame border including a supporting portion, a bending portion, and a connecting portion, wherein...

[0031] There are two opposing abutment parts, and the sides of the abutment parts are flush with the rigid frame;

[0032] The supporting part is bent at one end toward the rigid frame to form a bent part. The cross-section of the bent part is U-shaped and it supports the end of the locking member and the rigid frame.

[0033] There are two parallel connecting parts, and one of the connecting parts abuts against the flexible frame and the rigid frame.

[0034] In another aspect, the present invention provides another type of window, including the aforementioned aerogel laminated composite glass, and further including a composite frame, the composite frame including a plurality of interconnected frame borders, each frame border including a supporting portion, a bending portion, and a connecting portion, wherein,

[0035] There are two opposing abutment parts, and the abutment parts abut against the corner parts;

[0036] The bending part is located in the middle section of the supporting part. The cross-section of the bending part is U-shaped and supports the flat part. A second gap is left between the bending part and the corner part.

[0037] The end of the locking component is inserted into the bent portion;

[0038] There are two parallel connecting parts, and one of the connecting parts abuts against the flexible frame.

[0039] Finally, the present invention provides a method for preparing the above-mentioned aerogel sandwich composite glass, comprising the following steps:

[0040] S1. An adhesive layer is provided on both sides of the aerogel base layer, and the glass layer is pressed onto the adhesive layer;

[0041] S2. Preheat the glass layer until the adhesive layer melts, then place it into the mold along with the aerogel base layer and the adhesive layer.

[0042] S3. Pour molten rubber into the mold. The molten rubber combines with the adhesive layer and forms a flexible frame.

[0043] S4. Remove the aerogel base layer, adhesive layer, glass layer and flexible frame assembly from the mold;

[0044] S5. Press the locking element into the flexible frame.

[0045] The aerogel laminated composite glass, window, and preparation method of the present invention have the following advantages over the prior art:

[0046] (1) By setting a flexible frame that covers the aerogel base layer and the glass layer, and since the size of the aerogel base layer is larger than that of the glass layer, the flexible frame can penetrate the aerogel base layer. In this structure, the edges of the aerogel base layer and the glass layer are protected by the flexible frame, making them easy to handle and assemble. During assembly, the flexible frame can bear the force, thereby avoiding damage to the aerogel base layer and the glass layer, and also effectively preventing the flexible frame from falling off.

[0047] (2) In the flexible frame structure, the flat part supports the aerogel base layer, the corner part supports the adhesive layer and the glass layer, and the through part passes through the through hole of the aerogel base layer. In this way, when the glass layer is under stress or when the assembly is under stress, the flexible frame will bear the stress. When the flexible frame itself is under stress, the through part will support the flat parts on both sides to avoid squeezing the aerogel base layer, thereby ensuring the stability of the structure and preventing damage due to stress.

[0048] (3) By setting a rigid frame and supporting the flexible frame, the rigid frame will apply the force evenly to the flexible frame when under stress. Since the flexible frame is in contact with the aerogel substrate, this structure can ensure that the aerogel substrate is subjected to uniform stress and reduce the possibility of damage.

[0049] (4) By setting the locking part into two parts, a rod and a protrusion, it can be inserted into the flexible frame and the rigid frame. The rod can tighten the flexible frame and the rigid frame so that the rigid frame is not easy to fall off. The protrusion can also squeeze the flexible frame so that the locking part is not easy to fall off. At the same time, it can make the flexible frame fit more tightly with the glass layer to ensure structural strength.

[0050] (5) A window is formed by integrating the aerogel laminated glass with a composite frame; wherein the composite frame is composed of a frame, and the frame includes a supporting part, a bending part and a connecting part, which allows the composite frame to effectively snap the aerogel laminated glass with the bending part to ensure the stability of the structure; in another type of window structure, the bending part directly contacts the flexible frame and realizes the insertion with the locking part, which further improves the overall structural strength, and during assembly, the frames of the composite frame do not need to be welded or fused, which improves the convenience of assembly;

[0051] (6) In the preparation method of this aerogel composite glass, after the aerogel base layer and the glass layer are bonded together by the adhesive layer, the glass is preheated to reach the injection temperature and the adhesive layer melts. This can effectively combine with the rubber melt that constitutes the flexible frame to form an integrated structure, thereby improving the overall stability and preventing the glass from cracking due to excessive injection temperature.

[0069] The technical solutions of the present invention will be clearly and completely described below with reference to the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present invention.

[0070] like Figures 1-15 As shown, the aerogel laminated composite glass of the present invention includes an aerogel base layer 1, an adhesive layer 2, a glass layer 3, a flexible frame 4, a locking element 5, a rigid frame 6, a set screw 7, and a composite frame 8.

[0071] The window of the present invention includes the above-described aerogel laminated composite glass and a composite frame 8.

[0072] like Figures 1-4 , Figures 6-8As shown, adhesive layers 2 are provided on both sides of the aerogel base layer 1; glass layer 3 is bonded to the aerogel base layer 1 through adhesive layers 2, and the size of glass layer 3 is smaller than the size of aerogel base layer 1; flexible frame 4 covers the edges of aerogel base layer 1, adhesive layers 2 and glass layer 3, and a portion of flexible frame 4 penetrates aerogel base layer 1; locking member 5 penetrates flexible frame 4, and locking member 5 is interference-fitted with flexible frame 4 to tighten and lock aerogel base layer 1 and flexible frame 4;

[0073] As described above, the glass layer 3 and the aerogel base layer 1 are bonded together by the adhesive layer 2, and the size of the aerogel base layer 1 is larger than the size of the glass layer 3. This allows it to be connected to the flexible frame 4, and the flexible frame 4 can penetrate the aerogel base layer 1, so that the flexible frame 4, the aerogel base layer 1 and the glass layer 3 can be effectively combined, thereby ensuring the stability of the structure.

[0074] Meanwhile, a locking element 5 is inserted into the flexible frame 4. By relying on the interference fit between the locking element 5 and the flexible frame 4, the flexible frame 4 can be tightened so that the flexible frame 4 is more tightly bonded to the aerogel base layer 1 and the glass layer 3, preventing detachment and breakage at the through-point of the flexible frame 4.

[0075] In this structure, the edges of the aerogel base layer 1 and the glass layer 3 are protected by the flexible frame 4, which facilitates handling and assembly. During assembly, the flexible frame 4 can bear the force, thereby avoiding damage to the aerogel base layer 1 and the glass layer 3. At the same time, it can also effectively prevent the flexible frame 4 from falling off.

[0076] like Figure 4 and Figure 8 As shown, the flexible frame 4 includes a planar portion 41, a corner portion 42, and a through portion 43, all of which are integrally formed. The aerogel base layer 1 protrudes from the glass layer 3, and the protruding portion has a through hole 101. The planar portion 41 fits the protruding portion of the aerogel base layer 1 from the glass layer 3. The corner portion 42 fits the side of the adhesive layer 2 and the glass layer 3, as well as the side of the glass layer 3 away from the adhesive layer 2. The planar portion 41 and the corner portion 42 are provided on both sides of the aerogel base layer 1. The through portion 43 passes through the through hole 101, and the end of the through portion 43 is connected to the planar portions 41 on both sides of the aerogel base layer 1.

[0077] As described above, when the flexible frame 4 is set, the flat portions 41 on both sides of the aerogel base layer 1 are connected by the through portions 43 passing through the through holes 101, thus realizing the connection between the flexible frame 4 and the aerogel base layer 1.

[0078] In this structure, the aerogel base layer 1 is supported by the flat part 41, the adhesive layer 2 and the glass layer 3 are supported by the corner part 42, and the through part 43 passes through the through hole 101 of the aerogel base layer 1. Thus, when the glass layer 3 is subjected to force or assembly force, the flexible frame 4 will bear the load to avoid damage caused by force during handling and assembly.

[0079] Meanwhile, during assembly, the frame used for fixing will fully contact the flexible frame 4 without contacting the glass layer 3, thus achieving effective protection for the glass layer 3. Relying on the buffer of the flexible frame 4, it can also withstand a certain impact and reduce the probability of damage.

[0080] In this structure, when the flexible frame 4 is under stress, the through part 43 will support the flat parts 41 on both sides to avoid squeezing the aerogel base layer 1, thereby ensuring structural stability and preventing damage due to stress.

[0081] like Figure 2 and Figure 3 As shown, the rigid frame 6 is disposed on the surface of the flexible frame 4 away from the aerogel base layer 1 and the glass layer 3; the locking element 5 penetrates the rigid frame 6.

[0082] As described above, in order to further ensure the protective effect, a rigid frame 6 is provided on the flexible frame 4. By providing the rigid frame 6 and having the rigid frame 6 abut against the flexible frame 4, the rigid frame 6 will apply the force evenly to the flexible frame 4 when subjected to force. Since the flexible frame 4 is in contact with the aerogel base layer 1, this structure can ensure that the aerogel base layer 1 is subjected to force evenly, reducing the possibility of damage.

[0083] In this structure, the locking element 5 passes through the rigid frame 6 and achieves tension, thereby realizing the combination of the rigid frame 6 and the flexible frame 4. During assembly, for example, the door frame or window frame can contact the rigid frame 6.

[0084] like Figures 10-12 As shown, the locking member 5 includes a rod portion 51 and a protrusion 52, wherein the rod portion 51 passes through the flexible frame 4 and the rigid frame 6; two protrusions 52 are provided on the rod portion 51, and the protrusions 52 correspond to the glass layer 3.

[0085] As described above, the locking member 5 consists of two parts: a rod 51 and a protrusion 52. The rod 51 is used to pass through the flexible frame 4 and the rigid frame 6 to achieve a tensioning and fixing effect.

[0086] To further ensure the stability of the overall structure, a protrusion 52 is provided on the circumferential surface of the rod 51, and the protrusion 52 corresponds to the glass layer 3. Since glass has better structural strength than aerogel, the protrusion 52 is used to compress the flexible frame 4 corresponding to the glass layer 3, that is, the flat part 41 of the flexible frame 4, during fixing. This structure makes the position of the flexible frame 4 relative to the aerogel base layer 1 and the glass layer 2 more stable and tightly fitted, while it is not easy to deform itself, which helps to ensure the sealing during subsequent assembly and will not damage the aerogel base layer 1.

[0087] At the same time, this structure makes it difficult for the locking member 5 to come out, especially when the above frame has a relief groove for the locking member 5, so as to ensure structural stability.

[0088] like Figure 12 As shown, the rod 51 includes an elastic part 511 and a rigid part 512. There are two elastic parts 511 arranged opposite each other, and the two elastic parts 511 are connected by the rigid part 512. The elastic part 511 corresponds to the rigid frame 6. The rigid part 512 corresponds to the flexible frame 4. The protrusion 52 and the rigid part 512 are set as an integral structure.

[0089] As described above, the rod portion 51 of the locking member 5 is made of different materials. The elastic portion 511 corresponds to the rigid frame 6. The elastic portion 511 can be made of rubber to tighten the rigid frame 6. The rigid portion 512 can be made of metal to better penetrate the flexible frame 4 by relying on its own rigidity. At the same time, it can achieve tightening by relying on the protruding portion 52 of the integrated structure, thus ensuring its own tightening effect and the convenience of assembly.

[0090] like Figure 12 As shown, the set screw 7 passes through the elastic part 511 and is connected to the rigid part 512 by a threaded engagement; the head of the set screw 7 is recessed into the elastic part 511 to expand the elastic part 511.

[0091] As described above, by mounting a set screw on the rod 51, the head of the set screw 7 sinks into the elastic part 511, which causes the elastic part 511 to expand, thereby better tightening the rigid frame 6. At the same time, since the set screw 7 directly contacts the rigid part, it is also beneficial to increase the radial structural strength of the elastic part 511 by relying on the set screw 7, so as to ensure the stability of the rigid frame 6 installation.

[0092] like Figure 8 As shown, in a window structure of the present invention, a composite frame 8 surrounds the aerogel laminated composite glass and supports the flexible frame 4 and the rigid frame 6.

[0093] As described above, the composite frame 8 is a fixed window or door frame that surrounds the aerogel laminated composite glass and directly contacts the flexible frame 4 and the rigid frame 6. This prevents it from directly contacting the aerogel base layer 1 and the glass layer 3, thus avoiding damage to the aerogel laminated composite glass caused by impacts during assembly and ensuring the stability of the application.

[0094] like Figure 8 , Figure 9 and Figure 13 As shown, the composite frame 8 includes multiple interconnected frame edges 81. Each frame edge 81 includes a supporting portion 811, a bent portion 812, and a connecting portion 813. There are two supporting portions 811 arranged opposite each other, and the side of the supporting portion 811 is flush with the rigid frame 6. The supporting portion 811 is bent at one end toward the rigid frame 6 to form a bent portion 812. The cross-section of the bent portion 812 is U-shaped and supports the end of the locking member 5 and the rigid frame 6. There are two connecting portions 813 arranged in parallel, and one of the connecting portions 813 supports the flexible frame 4 and the rigid frame 6, and leaves a first gap 102 between it and the aerogel base layer 1.

[0095] As described above, the composite frame 8 is composed of multiple frame edges 81, which facilitates integration at the edge of the aerogel sandwich composite glass.

[0096] Preferably, the frame 81 is made of a flexible material. During assembly, the rigid frame 6 is clamped by two inwardly folded U-shaped bends 812, which can achieve relative fixation between the frame 81 and the aerogel laminated composite glass. Subsequently, multiple frames 81 are welded or fused together to form a window.

[0097] Specifically, a first gap 102 is left between the connecting part 813 of the composite frame 8 and the aerogel base layer 1, so as to avoid the connecting part 813 from contacting the aerogel base layer 1 and causing damage, thus ensuring the structural strength.

[0098] like Figure 5 and 14 As shown, in a window structure of the present invention, the composite frame 8 includes a plurality of interconnected frame edges 81. Each frame edge 81 includes a supporting portion 811, a bent portion 812, and a connecting portion 813. Two supporting portions 811 are arranged opposite each other, and the supporting portion 811 abuts against the corner portion 42. The bent portion 812 is located in the middle section of the supporting portion, and the cross-section of the bent portion 812 is U-shaped. It abuts against the flat portion 41, and a second gap 103 is left between the bent portion 812 and the corner portion 42. The end of the locking member 5 is inserted into the bent portion 812. Two connecting portions 813 are arranged parallel to each other, and one of the connecting portions 813 abuts against the flexible frame 4.

[0099] As described above, the difference between this window structure and the previous window structure is that the rigid frame 6 is not set, and the structure of the frame 81 is changed so that it directly contacts the flexible frame 4. This improves the sealing effect and the structural strength.

[0100] In this structure, the supporting part 811 is extended so that it can directly contact the side of the corner 42 away from the glass layer 3, rather than supporting the side of the corner 42. This allows for better clamping of the aerogel composite glass, while the locking part 5 is inserted into the bending part 812.

[0101] During assembly, the two supporting parts 811 of the frame 81 need to be separated relative to each other and then snapped onto the aerogel laminated glass. The bent part 812 has a relief groove to accommodate the locking part 5. A second gap 103 is left between the bent part 812 and the corner part 42 to avoid interfering with the return of the bent part 812 after it is folded with the supporting part 811, thereby ensuring assembly accuracy.

[0102] Meanwhile, this structure can effectively ensure the stability of the connection between the frame 81 and the aerogel laminated composite glass. There is no need to weld between the frames 81; they only need to be connected end to end to form the composite frame 8.

[0103] Furthermore, when the rod portion 51 of the locking member 5 adopts an elastic portion 511 and a rigid portion 512, the radial structural strength of the elastic portion 511 can be effectively improved after the set screw 7 is installed, which is also beneficial to ensuring the stability of the frame 81 snap-fit.

[0104] In some embodiments, to improve the structural strength of the aerogel, the aerogel may be modified to avoid damage under stress.

[0105] In some embodiments, the composite frame 8 is used only to enhance protection, and its outer side can be used to mount window frames or door frames.

[0106] like Figure 14 As shown, in some embodiments, the rigid frame 6 is used only for temporary protection to ensure the flatness of the surface of the flexible frame 4 and to prevent it from being damaged during handling and transportation, while the composite frame 8 is not provided.

[0107] When it is necessary to assemble to a door frame or window frame, since the rigid frame 6 is only tightened by the locking part 5, the rigid frame 6 can be directly removed. Then, the flexible frame 4 can be used to contact the door frame or window frame for assembly. This is beneficial to ensure the sealing effect of the connection with the frame through the flat surface of the flexible frame 4.

[0108] Specifically, in this embodiment, the frame has an clearance groove corresponding to the locking member 5 to avoid interference during assembly;

[0109] Specifically, in a structure with the composite frame 8 installed, it is suitable for use as an opening and closing window, while in a structure without the composite frame 8, it is suitable for use as a fixed window.

[0110] like Figure 15 As shown, in some embodiments, the locking member 5 also passes through the rigid frame 6, and when the frame 81 is installed, the frame 81 abuts against the rigid frame 6, and the locking member 5 passes through the bend 812 of the frame 81.

[0111] The method for preparing aerogel-laminated composite glass of the present invention includes the following steps:

[0112] S1. An adhesive layer 2 is provided on both sides of the aerogel base layer 1, and the glass layer 3 is pressed onto the adhesive layer 2.

[0113] S2. Preheat the glass layer 3 until the adhesive layer 2 melts, then place it together with the aerogel base layer 1 and the adhesive layer 2 into the mold.

[0114] S3. Pour molten rubber into the mold. The molten rubber combines with the adhesive layer 2 and forms a flexible frame 4.

[0115] S4. Remove the aerogel base layer 1, adhesive layer 2, glass layer 3 and flexible frame 4 from the mold;

[0116] S5. Press the locking element 5 into the flexible frame 4.

[0117] In the preparation method of this aerogel composite glass, after the aerogel base layer 1 and the glass layer 3 are bonded together by the adhesive layer 2, the glass layer 3 is preheated to the injection molding temperature and the adhesive layer 2 melts. In this way, the adhesive layer 2 can effectively combine with the rubber melt that constitutes the flexible frame 4 to form an integrated structure, thereby improving the overall stability and preventing the glass layer 3 from cracking due to the injection molding temperature.

[0118] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
