[0032] Next, in combination with the accompanying drawings and specific implementation manners, the present invention will be further described. It should be noted that, on the premise of no conflict, the following-described embodiments or technical features can be combined arbitrarily to form new embodiments. It should be known that the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts belong to the scope of protection of the present invention.

[0033] Please refer to Figures 1 to 12 , the present invention provides a technical solution: a sound-insulating laminated glass, which is composed of a glass main body and a frame.

[0034] The sound insulation performance of the glass body is improved by laminating and hollowing. The laminated part is composed of an outer glass 1, a middle glass 2 and a laminated layer 3, and the laminated layer 3 adopts double-layer lamination, and a sound insulation layer 4 is arranged between the two layers of lamination. The laminated layer 3 adopts PVB material, which can achieve full-band sound insulation effect, and the sound insulation layer 4 adopts UV-cured acrylic polymer glue, which is mainly used to shield high-frequency sound waves. Furthermore, the outer glass 1 can be surface-treated by etching to enhance the sound insulation effect by surface diffusion. At the same time, a hollow frame 5 is installed on the middle glass 2 by gluing, and the other side of the hollow frame 5 is glued to the inner glass 6. The inner glass 6 adopts single-layer glass or multi-layer glass. The hollow frame 5 is filled with inert gas to further improve the sound insulation performance of the glass body.

[0035] A sealing ring 7 is mounted on the outer wall of the hollow frame 5, and the sealing ring 7 is connected to the hollow frame 5, the middle glass 2 and the inner glass 6 at the same time to fill the gaps and prevent the inert gas in the hollow frame 5 from leaking from the joints. At the same time, the height difference and the gap between the hollow frame 5, the middle glass 2 and the inner glass 6 are further filled by a sealing layer 8, and the sealing layer 8 covers the sealing ring 7. The sealing layer 8 adopts modified EPDM rubber, and a main frame 9 is glued and installed on the edge of the entire glass body through the sealing layer 8.

[0036] The main frame 9 is the main body of the frame part. When the sound insulation laminated glass is a rectangular parallelepiped as a whole, the main frame 9 is assembled from two vertical beams and two horizontal beams, which can reinforce the edge of the glass and provide a positioning point for subsequent use and transportation.

[0037] The main frame 9 adopts a hollow structure, and a zigzag partition 10 is arranged in the middle of its inner cavity. The zigzag structure can block the straight-line propagation path of sound waves, and the inner cavity is divided into a load-bearing cavity and a damping cavity through the partition 10. The load-bearing cavity is located in the outer layer of the main frame 9, and a fork-shaped support rod 11 is arranged therein to play a role of structural reinforcement support. The damping cavity is filled with a mixture of high-density polyurethane foam and microspheres to further block sound propagation and improve the sound insulation performance of the glass edge.

[0038] There are reserved holes 12 provided on the vertical beams of the main frame 9. Through the reserved holes 12, the installation of the protective transportation frame can be facilitated. The transportation frame is composed of two vertical baffles 13 and two horizontal baffles 14. On both sides of the vertical baffle 13, there are side clamping plates 15. The vertical baffle 13 is buckled on the outer wall of the vertical beam of the main frame 9 through the side clamping plates 15. And on the side clamping plates 15, elastic insertion posts 16 are movably installed. In the normal state, the elastic insertion posts 16 retract into the side clamping plates 15. There is a cavity in the side clamping plates 15. At the end of the side clamping plate 15 close to the horizontal baffle 14, there is a movable end block 18. A pressure rod 19 is fixedly connected to the movable end block 18. The pressure rod 19 is located in the cavity of the side clamping plate 15. An inclined block 17 is installed on the elastic insertion post 16. When assembling the horizontal baffle 14, the horizontal baffle 14 can compress the movable end block 18, so that the movable end block 18 drives the pressure rod 19 to move. The pressure rod 19 can push the inclined block 17 and the elastic insertion post 16, so that the elastic insertion post 16 enters the reserved hole 12, thereby fixing the vertical baffle 13 on the main frame 9.

[0039] Further, at both ends of the vertical baffle 13, there are mating holes 20 for the installation of the horizontal baffle 14. The horizontal baffle 14 adopts a hollow structure, in which an elastic socket 21 is installed in a limited sliding manner. The elastic socket 21 can automatically extend under the action of elastic force. When the elastic socket 21 enters the mating hole 20, the horizontal baffle 14 can be fixed on the vertical baffle 13.

[0040] On the horizontal baffle 14, there is a clamping seat 22. Through the clamping seat 22, the partition plate 28 can be connected. On the partition plate 28, there are corresponding clamping parts 30. When the partition plate 28 is abutted against the horizontal baffle 14, the clamping parts 30 and the clamping seat 22 are deformed and engaged, which can prevent the partition plate 28 from falling off the horizontal baffle 14. At the same time, a rotating shaft 23 is rotatably installed in the clamping seat 22. At both ends of the rotating shaft 23, a turntable 24 and a magnetic block 26 are respectively installed. The edge of the turntable 24 is connected with a traction rope 25. The traction rope 25 can enter the cavity of the horizontal baffle 14 and is connected to the tail of the elastic socket 21. Therefore, when the turntable 24 rotates, it can drive the elastic socket 21 to retract by pulling the traction rope 25. After the elastic socket 21 pops out, the turntable 24 is at the initial angle. On the clamping part 30 of the partition plate 28, there is a magnetic seat 31. When the partition plate 28 is abutted and combined on the horizontal baffle 14, the magnetic force of the magnetic seat 31 can guide the magnetic block 26 to rotate, and then drive the turntable 24 to rotate, driving the elastic socket 21 to retract, so as to facilitate the combination of the horizontal baffle 14 on the vertical baffle 13, compress the movable end block 18, so that the vertical baffle 13 is connected to the main frame 9. Subsequently, the partition plate 28 is separated from the horizontal baffle 14, so that the magnetic force of the magnetic seat 31 is not enough to drive the magnetic block 26 and the turntable 24 to rotate. The elastic force of the elastic socket 21 makes it automatically pop out and enter the mating hole 20 to complete the installation of the horizontal baffle 14. The vertical baffle 13 and the horizontal baffle 14 form a complete transportation frame, which can play a protective role for the glass and the main frame 9.

[0041] A side eaves 27 is provided on the side splint 15. When the cross baffle 14 is aligned with the vertical baffle 13, the partition board 28 can enter the slide rail formed by the side eaves 27, so that the partition board 28 can slide while fitting on the surface of the glass. Slide the partition board 28 away from the cross baffle 14. When the vertical baffle 13 and the cross baffle 14 are combined, the partition board 28 can be in the middle of the glass. A buffer member 29 is provided on the surface of the partition board 28 for protection. When the size of the produced glass is large, the glass is divided into multiple parts for independent support, which can increase its flexural strength and impact resistance. When transporting the glass, it is possible to stack large pieces of glass more safely, and it is supported and protected by the transport frame and the partition board 28, avoiding the situation of glass fragmentation or inert gas leakage, and reducing transportation damage. When the glass is officially used, the partition board 28 can be first reattached to the cross baffle 14 and connected to the card seat 22 through the clip 30, so that the cross baffle 14 can be detached from the vertical baffle 13, and then the vertical baffle 13 can also be quickly detached from the main frame 9, ensuring that the glass can be quickly put into use.

[0042] The preparation method of the sound-insulating laminated glass includes the following steps: I. Preparation of the glass body First, perform glass pretreatment. Cut, grind and clean the outer layer glass 1, the middle layer glass 2 and the inner layer glass 6 to remove surface impurities and oil stains. Then, perform etching treatment on the surface of the outer layer glass 1 to form a diffuse reflection microstructure with a depth of 50-100 μm and a spacing of 200-300 μm. Then, assemble the interlayer 3. Coat the PVB film on the middle layer glass 2 and the outer layer glass 1, and lay the UV-curable acrylic polymer sound-insulating layer 4 between the two PVB interlayers 3. Use the vacuum bag pressing method for pre-pressing. The pressing conditions are a temperature of 70 °C, a pressure of 0.3 MPa, and a time of 10-15 min. Then, bond the hollow frame 5 to the side of the middle layer glass 2 through structural adhesive, and then press the inner layer glass 6 on the hollow frame 5 and fill it with inert gas, where the argon concentration is ≥90%. Finally, fit the ethylene propylene diene monomer rubber seal ring 7 on the hollow frame 5, coat the modified EPDM sealant layer 8, and perform the assembly of the main frame 9 and then cure it at room temperature for 24 hours.

[0043] II. Assembly of the main frame 9 First, perform profile processing. Cut the aluminum alloy profile into vertical beams and cross beams, install the folded partition 10 in the profile cavity, weld the X-shaped support rods 11 in the load-bearing cavity, inject a mixture of polyurethane foam and glass microspheres into the damping cavity, and the ratio of the two is 3:1. After curing, an acoustic absorption layer is formed. Connect the vertical beam and the cross beam to the edge of the glass through the sealant layer 8, and then remove the excess glue.

[0044] III. Installation of the transport frame The vertical baffle 13 is buckled on the vertical beam of the main frame 9 through the side splints 15, and the elastic insertion post 16 locking mechanism is triggered by inserting the horizontal baffle 14 to complete the connection of the vertical baffle 13. Subsequently, the partition plate 28 is moved to the middle of the glass to complete the connection of the horizontal baffle 14.

[0045] Although embodiments of the present invention have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
