Description

Technical Field

[0001] The present invention relates to the technical field of multi-layer glass, in particular to a sound-insulating laminated glass and a preparation method thereof. Background Art

[0002] With the acceleration of urbanization and the intensification of traffic noise pollution, the demand for architectural soundproofing glass has grown significantly. Traditional soundproofing glass, primarily using single-layer laminated or hollow structures, has performance limitations: ordinary PVB laminated glass provides insufficient sound insulation against low-frequency noise, while hollow glass has poor structural reliability and is prone to breakage and leakage.

[0003] Stress concentration at the edges of large-sized glass can easily lead to self-explosion. The traditional aluminum frame structure currently used for large-sized glass can increase the strength of the glass, but its sound bridge effect significantly reduces the overall sound insulation. At the same time, the breakage rate of large-sized glass panels during transportation is high, and the disassembly and assembly of the existing protective frame is time-consuming, affecting construction efficiency.

DETAILED DESCRIPTION

[0043] The present invention is further described below in conjunction with the accompanying drawings and specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments. It should be noted that 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 making creative work are within the scope of protection of the present invention.

[0044] See also Figures 1 to 12 The present invention provides a technical solution: a sound-insulating laminated glass, which consists of a glass body and a frame.

[0045] The sound insulation performance of the glass body is improved by laminating and hollowing. The laminated part is composed of an outer layer of glass 1, a middle layer of glass 2 and a laminated layer 3, and the laminated layer 3 adopts double-layer lamination. 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 layer of 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 layer of glass 2 by gluing, and the other side of the hollow frame 5 is glued to the inner layer of glass 6. The inner layer of 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.

[0046] A sealing ring 7 is mounted on the outer wall of the hollow frame 5. 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 gaps between the hollow frame 5, the middle glass 2 and the inner glass 6 are further filled by a sealing layer 8. The sealing layer 8 covers the sealing ring 7. The sealing layer 8 adopts modified EPDM rubber. The main frame 9 is glued and installed on the edge of the entire glass body through the sealing layer 8.

[0047] The main frame 9 is the main body of the frame part. When the soundproof 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.

[0048] The main frame 9 adopts a hollow structure, and a zigzag partition 10 is provided 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 provided therein to play the 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.

[0049] The vertical beam of the main frame 9 is provided with a reserved hole 12, through which the installation of the protective transport frame can be achieved. The transport frame is composed of two vertical baffles 13 and two transverse baffles 14. Side plywood 15 is provided on both sides of the vertical baffle 13. The vertical baffle 13 is buckled on the outer wall of the vertical beam of the main frame 9 through the side plywood 15, and elastic plug-in columns 16 are movably installed on the side plywood 15. The elastic plug-in columns 16 are normally retracted in the side plywood 15. A cavity is provided in the side plywood 15. When the side plywood 15 is close to the transverse baffle 1 4 is provided with a movable end block 18, and 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, and an inclined block 17 is installed on the elastic plug column 16. When the cross baffle 14 is assembled, the cross baffle 14 can compress the movable end block 18, so that the movable end block 18 drives the pressure rod 19 to move, and the pressure rod 19 can push the inclined block 17 and the elastic plug column 16, so that the elastic plug column 16 enters the reserved hole 12, thereby fixing the vertical baffle 13 on the main frame 9.

[0050] Furthermore, both ends of the vertical baffle 13 are provided with matching holes 20 for installing the transverse baffle 14. The transverse baffle 14 adopts a hollow structure, in which an elastic socket 21 is installed for limiting sliding. The elastic socket 21 can automatically extend under the action of elastic force. When the elastic socket 21 enters the matching hole 20, the transverse baffle 14 can be fixed on the vertical baffle 13.

[0051] The cross baffle 14 is provided with a base 22, through which the partition plate 28 can be connected. The partition plate 28 is provided with a corresponding clamp 30. When the partition plate 28 is placed against the cross baffle 14, the clamp 30 and the base 22 are deformed and engaged, which can prevent the partition plate 28 from falling off the cross baffle 14. At the same time, a rotating shaft 23 is rotatably installed in the base 22, and a turntable 24 and a magnetic block 26 are respectively installed at both ends of the rotating shaft 23. A traction rope 25 is connected to the edge of the turntable 24. The traction rope 25 can enter the cavity of the cross baffle 14 and is connected to the tail of the elastic socket 21. Therefore, when the turntable 24 rotates, the elastic socket 21 can be pulled by the traction rope 25 to retract. After the elastic socket 21 pops out, the turntable 24 is in its initial state. At the starting angle, a magnetic base 31 is provided on the clamp 30 of the partition plate 28. When the partition plate 28 is abutted and assembled on the transverse baffle 14, the magnetic force of the magnetic base 31 can guide the magnetic block 26 to rotate, thereby causing the turntable 24 to rotate, driving the elastic socket 21 to retract, so as to facilitate the combination of the transverse baffle 14 on the vertical baffle 13, compressing the movable end block 18, so that the vertical baffle 13 is connected to the main frame 9, and then the partition plate 28 is moved away from the transverse baffle 14, so that the magnetic force of the magnetic base 31 is not enough to drive the magnetic block 26 and the turntable 24 to rotate, and the elastic force of the elastic socket 21 causes it to automatically pop out and enter the mounting hole 20, completing the installation of the transverse baffle 14. The vertical baffles 13 and the transverse baffles 14 constitute a complete transport frame, which can protect the glass and the main frame 9.

[0052] The side splints 15 are provided with side eaves 27. When the horizontal baffle 14 is aligned with the vertical baffle 13, the partition plate 28 can enter the slide rail formed by the side eaves 27, so that the partition plate 28 can slide on the surface of the glass. When the partition plate 28 is slid away from the horizontal baffle 14 and the vertical baffle 13 and the horizontal baffle 14 are combined, the partition plate 28 can be in the middle of the glass. The surface of the partition plate 28 is provided with a buffer 29 for protection. When the glass produced is large in size, the glass is divided into multiple parts for independent support, which can increase its bending strength and impact resistance. When transporting the glass, large pieces of glass can be stacked more safely. The transport frame and the partition plate 28 provide support and protection to avoid glass breakage or inert gas leakage, thereby reducing transportation losses. When the glass is officially used, the partition plate 28 can be re-attached to the horizontal baffle 14 and connected to the base 22 through the clamp 30, so that the horizontal baffle 14 can be detached from the vertical baffle 13, and then the vertical baffle 13 can also be quickly released from the main frame 9, ensuring that the glass can be put into use quickly.

[0053] The preparation method of the sound-insulating laminated glass comprises the following steps:

[0054] 1. Preparation of glass body

[0055] First, the glass is pre-treated. The outer glass 1, middle glass 2, and inner glass 6 are cut, edged, and cleaned to remove surface impurities and oil. The outer glass 1 is then etched to form a diffuse reflective microstructure with a depth of 50-100μm and a spacing of 200-300μm. The interlayer 3 is then assembled. PVB film is applied to the middle glass 2 and outer glass 1, and a UV-curable acrylic polymer sound insulation layer 4 is placed between the two PVB interlayers 3. Pre-lamination is performed using a vacuum bagging method at a temperature of 70°C, a pressure of 0.3MPa, and a time of 10-15 minutes. The hollow frame 5 is then bonded to the side of the middle glass 2 using structural adhesive. The inner glass 6 is then pressed onto the hollow frame 5 and filled with inert gas, with an argon concentration of ≥90%. Finally, an EPDM rubber sealant 7 is installed on the hollow frame 5, and a modified EPDM sealant 8 is applied. After assembly of the main frame 9, the frame is cured at room temperature for 24 hours.

[0056] 2. Main frame 9 assembly

[0057] First, the profile is processed. The aluminum alloy profile is cut into vertical beams and horizontal beams. A broken-line partition 10 is installed in the inner cavity of the profile. An X-shaped support rod 11 is welded in the load-bearing cavity. A mixture of polyurethane foam and glass microspheres is injected into the damping cavity in a ratio of 3:1. After curing, a sound-absorbing layer is formed. The vertical beams and horizontal beams are cured and connected to the edge of the glass through the adhesive sealing layer 8, and then the excess colloid is removed.

[0058] 3. Transport frame installation

[0059] The vertical baffle 13 is fastened to the vertical beam of the main frame 9 through the side clamping plate 15, and the horizontal baffle 14 is inserted to trigger the elastic plug column 16 locking mechanism to complete the connection of the vertical baffle 13. Then the partition plate 28 is moved to the middle of the glass to complete the connection of the horizontal baffle 14.

[0060] While embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions, and variations may be made to these embodiments without departing from the principles and spirit of the invention, and that the scope of the invention is defined by the appended claims and their equivalents.
