Description

Technical Field

[0001] The invention relates to the technical field of laminated glass, and in particular to an aerogel laminated composite glass, a window and a preparation method thereof. Background Art

[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. The low thermal conductivity and excellent sound insulation properties of aerogel are used to achieve thermal insulation and sound insulation effects. It is widely used in construction, aerospace and high-end vehicles.

[0003] The existing invention patent application with application publication number CN109963822A discloses a thermal insulation sheet, an intermediate film for laminated glass and laminated glass, wherein the laminated glass comprises a thermal insulation sheet, and the thermal insulation sheet comprises a laminate of an aerogel layer of aerogel and a resin layer comprising a thermoplastic resin laminated on at least one surface of the aerogel layer;

[0004] As in the above scheme, the aerogel layer and other layers adopt a stacked structure, but lack edge treatment; since aerogel has a porous structure, it may break when slightly impacted. It is a fragile material like glass, so it is easy to break during subsequent transportation and installation, affecting the stability of the structure;

[0005] There is also a utility model patent with authorization announcement number CN205046712U, which 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, wherein the coating is provided on one side of the outer layer of glass, the coating is provided 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] In this technical solution, the fixing structure of aerogel laminated glass is mentioned, that is, bolts are passed through the glass and the aerogel layer to achieve connection with the concave base, but it is relatively difficult to open holes in the glass, and when inserting the bolts for tightening, if the angle is improper and the bolts collide, it is also very easy to cause damage to the aerogel layer and the glass; therefore, there is an urgent need to improve the existing aerogel laminated glass structure. Summary of the invention

[0029] On the other hand, the present invention provides a window, comprising the above-mentioned aerogel laminated composite glass, and also comprising a composite frame, the composite frame surrounds the aerogel laminated composite glass and supports the flexible frame and the rigid frame.

[0030] On the basis of the above technical solution, preferably, the composite frame includes a plurality of mutually connected frames, the frames include a supporting portion, a bending portion and a connecting portion, wherein:

[0037] The end of the locking member is plugged into the bent portion;

[0038] Two connecting parts are arranged in parallel, 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. Adhesive layers are arranged on both sides of the aerogel base layer, and a glass layer is pressed onto the adhesive layer;

[0041] S2, preheating the glass layer until the adhesive layer melts, and then placing the glass layer, the aerogel base layer and the adhesive layer into the mold;

[0042] S3, pouring molten rubber into the mold, the molten rubber combines with the adhesive layer, and at the same time forms a flexible frame;

[0043] S4, taking out the aerogel base layer, the adhesive layer, the glass layer and the flexible frame combination from the mold;

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

[0045] The aerogel laminated composite glass, window and preparation method thereof of the present invention have the following beneficial effects compared with the prior art:

[0046] (1) A flexible frame is provided to cover the aerogel base layer and the glass layer. 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 flexible frame is used to protect the edges of the aerogel base layer and the glass layer, making it easier to carry and assemble. During assembly, the flexible frame can bear the force, thereby avoiding damage to the aerogel base layer and the glass layer. At the same time, the flexible frame can also be effectively prevented from falling off.

[0047] (2) In the flexible frame structure, the plane part supports the aerogel base layer, the corner part supports the adhesive layer and the glass layer, and the through-hole part passes through the through-hole of the aerogel base layer. In this way, when the glass layer is subjected to stress or when the assembly is subjected to stress, the flexible frame will bear the stress. When the flexible frame itself is subjected to stress, the through-hole part will support the plane 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, when a force is applied, the rigid frame will evenly apply the force to the flexible frame. Since the flexible frame contacts the aerogel base layer, this structure can ensure that the aerogel base layer is evenly stressed, thereby reducing the possibility of damage.

[0049] (4) The locking member is provided with a rod and a protruding portion, so that the locking member can be inserted into the flexible frame and the rigid frame, wherein the rod can tighten the flexible frame and the rigid frame to prevent the rigid frame from falling off; and the protruding portion can also squeeze the flexible frame to prevent the locking member from falling off, and at the same time, the flexible frame can be more closely attached to the glass layer to ensure structural strength;

[0050] (5) The aerogel laminated glass is integrated with a composite frame to form a window; wherein the composite frame is composed of a frame, and the frame includes a supporting portion, a bending portion and a connecting portion, so that the composite frame can rely on the bending portion to effectively clamp the aerogel laminated composite glass, thereby ensuring the stability of the structure; in another window structure, the bending portion directly contacts the flexible frame and realizes the plug-in connection with the locking member, which further improves the overall structural strength, and during assembly, the frames of the composite frame do not need to be welded or fused, thereby improving the convenience of assembly;

[0051] (6) In the preparation method of the aerogel composite glass, after the aerogel base layer and the glass layer are bonded by the adhesive layer, the glass is preheated to the injection molding temperature and the adhesive layer is melted, so that it can be effectively combined with the rubber melt constituting the flexible frame to form an integrated structure, thereby improving the overall stability and preventing the glass from bursting due to excessively high injection molding temperature.

DETAILED DESCRIPTION

[0069] The following will be combined with the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0070] like Figures 1 to 15 As shown, the aerogel sandwich composite glass of the present invention comprises an aerogel base layer 1, an adhesive layer 2, a glass layer 3, a flexible frame 4, a locking member 5, a rigid frame 6, a set screw 7 and a composite frame 8;

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

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

[0073] As in the above structure, the glass layer 3 is bonded to the aerogel base layer 1 through the bonding layer 2, and the size of the aerogel base layer 1 is larger than that of the glass layer 3, so that it can 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 can be effectively combined with the aerogel base layer 1 and the glass layer 3, thereby ensuring the stability of the structure;

[0074] At the same time, a locking member 5 is inserted into the flexible frame 4. By relying on the interference fit between the locking member 5 and the flexible frame 4, the flexible frame 4 can be tightened to make the flexible frame 4 more closely combined with the aerogel base layer 1 and the glass layer 3, thereby preventing the problem of separation and the problem of fracture of the flexible frame 4 at the penetration position.

[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 makes it easy to carry and assemble. During assembly, the flexible frame 4 can be subjected to force, thereby avoiding damage to the aerogel base layer 1 and the glass layer 3, and at the same time, it can effectively prevent the flexible frame 4 from falling off.

[0076] like Figure 4 and Figure 8 As shown, the flexible frame 4 includes a plane portion 41, a corner portion 42 and a through portion 43 of an integrated structure, the aerogel base layer 1 protrudes compared to the glass layer 3, and a through hole 101 is provided in the protruding portion, wherein the plane portion 41 is in contact with the protruding portion of the aerogel base layer 1 compared to the glass layer 3; the corner portion 42 is in contact with the side surfaces of the adhesive layer 2 and the glass layer 3, and the side of the glass layer 3 away from the adhesive layer 2; the plane portion 41 and the corner portion 42 are arranged on both sides of the aerogel base layer 1; the through portion 43 passes through the through hole 101, and the ends of the through portion 43 are connected to the plane portions 41 on both sides of the aerogel base layer 1;

[0077] As in the above structure, when the flexible frame 4 is provided, the planar portions 41 on both sides of the aerogel base layer 1 are connected through the through portions 43 passing through the through holes 101, thereby achieving the connection between the flexible frame 4 and the aerogel base layer 1;

[0078] In this structure, the plane portion 41 is used to support the aerogel base layer 1, the corner portion 42 is used to support the adhesive layer 2 and the glass layer 3, and the through portion 43 passes through the through hole 101 of the aerogel base layer 1, so that when the glass layer 3 is subjected to stress or when it is assembled, it will be borne by the flexible frame 4, so as to avoid damage caused by stress during transportation and assembly.

[0079] At the same time, during assembly, the fixing frame will completely contact the flexible frame 4, but will not contact the glass layer 3, so that the glass layer 3 can be effectively protected. Relying on the buffering 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 itself is subjected to stress, the through-portions 43 will support the planar portions 41 on both sides to avoid squeezing the aerogel base layer 1, thereby ensuring that the structure is stable and will not be damaged due to stress.

[0081] like Figure 2 and Figure 3 As shown, the rigid frame 6 is arranged on the surface of the flexible frame 4 away from the aerogel base layer 1 and the glass layer 3; the locking member 5 passes through the rigid frame 6;

[0082] As in the above structure, 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 the rigid frame 6 being supported on the flexible frame 4, when force is applied, the rigid frame 6 will apply force evenly to the flexible frame 4. Since the flexible frame 4 contacts the aerogel base layer 1, this structure can ensure that the aerogel base layer 1 is evenly stressed, thereby reducing the possibility of damage.

[0083] In this structure, the locking member 5 simultaneously passes through the rigid frame 6 and is tightened, thereby realizing the combination of the rigid frame 6 and the flexible frame 4. During assembly, for example, the door frame or the window frame contacts 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 arranged on the rod portion 51, and the protrusions 52 correspond to the glass layer 3;

[0085] As shown in the above structure, the locking member 5 is composed of a rod 51 and a protruding portion 52, wherein the rod 51 is used to pass through the flexible frame 4 and the rigid frame 6 to achieve a tightening and fixing effect;

[0086] In order to further ensure the stability of the overall structure, a protrusion 52 is provided on the circumference 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 squeeze the flexible frame 4 corresponding to the glass layer 3, that is, the plane portion 41 of the flexible frame 4 when fixing. The setting of this structure can make the position of the flexible frame 4 relative to the aerogel base layer 1 and the glass layer 2 more stable and closely fitted, and at the same time, it is not easy to deform itself, which is conducive to ensuring 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 fall out, especially when the frame is provided with an avoidance groove corresponding to the locking member 5, so as to ensure the stability of the structure.

[0088] like Fig.12 As shown, the rod portion 51 includes an elastic portion 511 and a rigid portion 512, wherein two elastic portions 511 are arranged opposite to each other, the two elastic portions 511 are connected by the rigid portion 512, and the elastic portion 511 corresponds to the rigid frame 6; the rigid portion 512 corresponds to the flexible frame 4, and the protrusion 52 and the rigid portion 512 are arranged as an integrated structure;

[0089] As in the above structure, the rod portion 51 of the locking member 5 is made of different materials, wherein the elastic portion 511 corresponds to the rigid frame 6, and 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 rely on its own rigidity to better penetrate the flexible frame 4, and at the same time it can be tightened by relying on the protruding portion 52 of the integrated structure, thereby ensuring its own tightening effect and convenience of assembly.

[0090] like Fig.12 As shown, the set screw 7 penetrates the elastic part 511 and is connected with the rigid part 512 by threaded engagement; the head of the set screw 7 sinks into the elastic part 511 to expand the elastic part 511;

[0091] As in the above structure, by assembling a set screw on the rod 51, the head of the set screw 7 sinks into the elastic part 511, which can expand the elastic part 511, 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 rely on the set screw 7 to increase the radial structural strength of the elastic part 511, so as to ensure the stability of the installation of the rigid frame 6.

[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 abuts against the flexible frame 4 and the rigid frame 6;

[0093] As in the above structure, the composite frame 8 is a fixed window frame or door frame, which surrounds the aerogel laminated composite glass and directly contacts the flexible frame 4 and the rigid frame 6, so that it does not directly contact the aerogel base layer 1 and the glass layer 3, thereby avoiding damage to the aerogel laminated composite glass caused by impact during assembly, thereby ensuring the stability of the application.

[0094] like Figure 8 , Fig. 9 and Fig.13 As shown, the composite frame 8 includes a plurality of mutually connected frames 81, and the frame 81 includes a supporting portion 811, a bending portion 812 and a connecting portion 813, wherein two supporting portions 811 are arranged opposite to each other, and the side surface of the supporting portion 811 is flush with the rigid frame 6; the supporting portion 811 is bent toward one end of the rigid frame 6 to form a bending portion 812, and the cross section of the bending portion 812 is U-shaped, and it resists the end of the locking member 5 and the rigid frame 6; two connecting portions 813 are arranged in parallel, and one of the connecting portions 813 resists the flexible frame 4 and the rigid frame 6, and leaves a first gap 102 between the aerogel base layer 1;

[0095] As in the above structure, the composite frame 8 is composed of a plurality of frames 81, so as to facilitate integration at the edge of the aerogel laminated composite glass;

[0096] Preferably, the frame 81 is made of an elastic material. When assembling, the rigid frame 6 is clamped by two inwardly folded U-shaped bent portions 812, so that the frame 81 and the aerogel laminated composite glass can be relatively fixed. Subsequently, multiple frames 81 are welded or fused to form a window.

[0097] Specifically, a first gap 102 is left between the connection portion 813 of the composite frame 8 and the aerogel base layer 1, so as to avoid the connection portion 813 contacting the aerogel base layer 1 and causing damage, thereby ensuring 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 mutually connected frames 81, the frames 81 include a butting portion 811, a bending portion 812 and a connecting portion 813, wherein two butting portions 811 are arranged opposite to each other, and the butting portions 811 butt against the corner portion 42; the bending portion 812 is arranged in the middle section of the butting portion, the cross section of the bending portion 812 is U-shaped, and butts against the plane portion 41, and a second gap 103 is left between the bending portion 812 and the corner portion 42; the end of the locking member 5 is plugged into the bending portion 812; two connecting portions 813 are arranged in parallel, and one of the connecting portions 813 butts against the flexible frame 4;

[0099] As described above, the present window structure is different from the previous window structure in that the rigid frame 6 is not provided, and the structure of the frame 81 is changed so that it directly contacts the flexible frame 4, which improves the sealing effect and the structural strength;

[0100] In this structure, the abutting portion 811 is extended, and can directly contact the side of the corner portion 42 away from the glass layer 3, rather than abutting the side of the corner portion 42, so that the aerogel composite glass can be better clamped, and the locking member 5 is plugged into the bent portion 812;

[0101] In this way, during assembly, the two abutting portions 811 of the frame 81 need to be relatively separated and then clamped onto the aerogel laminated composite glass. The bent portion 812 is provided with an avoidance groove to accommodate the locking member 5; and a second gap 103 is left between the bent portion 812 and the corner portion 42 to avoid interference with the return of the bent portion 812 after following the abutting portion 811 to ensure assembly accuracy.

[0102] At the same time, this structure can effectively ensure the stability of the combination between the frame 81 and the aerogel laminated composite glass. There is no need for welding between the frames 81, and the composite frame 8 can be formed by simply connecting the ends.

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

[0104] In some embodiments, in order to improve the structural strength of the aerogel, the aerogel may be modified aerogel to avoid damage due to force.

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

[0106] like Fig.14 As shown, in some embodiments, the rigid frame 6 is only used 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, and the composite frame 8 is not provided;

[0107] When it is necessary to assemble to the door frame or window frame, since the rigid frame 6 is only tightened by the locking member 5, the rigid frame 6 can be directly removed, and then the flexible frame 4 can be assembled with the door frame or window frame in contact, which is conducive to ensuring 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 is provided with an avoidance groove corresponding to the locking member 5 to avoid interference during assembly;

[0109] Specifically, in a structure in which the composite frame 8 is installed, it is suitable for use as an opening and closing window, while in a structure in which the composite frame 8 is not installed, it is suitable for use as a fixed window.

[0110] like Fig.15 As shown, in some embodiments, the locking member 5 passes through the rigid frame 6 at the same time, and when the frame 81 is installed, the frame 81 abuts against the rigid frame 6, and the locking member 5 passes through the bent portion 812 of the frame 81.

[0111] The method for preparing the aerogel sandwich composite glass of the present invention comprises the following steps:

[0112] S1, providing an adhesive layer 2 on both sides of the aerogel base layer 1, and pressing a glass layer 3 onto the adhesive layer 2;

[0113] S2, preheating the glass layer 3 until the adhesive layer 2 melts, and then placing the glass layer 3 together with the aerogel base layer 1 and the adhesive layer 2 into a mold;

[0114] S3, pouring molten rubber into the mold, the molten rubber combines with the adhesive layer 2, and at the same time forms a flexible frame 4;

[0115] S4, taking out the combination of the aerogel base layer 1, the adhesive layer 2, the glass layer 3 and the flexible frame 4 from the mold;

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

[0117] In the preparation method of the aerogel composite glass, after the aerogel base layer 1 and the glass layer 3 are bonded by the adhesive layer 2, the glass layer 3 is preheated to reach the injection molding temperature, and the adhesive layer 2 is melted, so that the adhesive layer 2 can be effectively combined with the rubber melt constituting the flexible frame 4 to form an integrated structure, thereby improving the overall stability, and the glass layer 3 will not burst 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 in the protection scope of the present invention.
