Abstract
Description
Technical Field
[0001] The utility model relates to the production of hollow glass, in particular to a long-term sealed built-in sunshade hollow glass. Background Art
[0002] The current built-in louver hollow glass has the following defects when used in buildings: 1. The louver frame and corresponding accessories inside it have a certain weight, especially the louver hollow glass with a larger area. The traditional built-in louver hollow glass is sealed only by butyl rubber. During the long-term use of the louver system, the sealant is subjected to long-term reciprocating shear force, and the shear resistance of butyl rubber is limited, and it does not have the structural bonding strength to maintain. Over time, the sealing system capacity of the hollow glass is weakened, especially the airtightness is weakened; 2. The built-in louver hollow glass is used in buildings and is subjected to high and low temperatures for a long time. The inert gas inside is repeatedly heated and expanded or pre-cooled and contracted, which weakens the sealing. No matter which of the above defects causes the airtightness of the built-in hollow glass to be weakened, gas exchange will occur with the outside world, causing the inert gas to be lost, thereby weakening its heat insulation, noise prevention and other functions, reducing the energy-saving effect and shortening the service life. Therefore, a long-term sealed built-in sunshade hollow glass has been developed. Utility Model Content
[0003] The utility model aims to solve the problem that the built-in sunshade hollow glass has weak sealing performance and poor sound insulation and heat insulation effects after long-term use, and proposes a long-acting sealed built-in sunshade hollow glass.
[0004] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0006] Preferably, the distance between the first glass and the second glass is A mm. Before the glasses are laid together, a circle of 4SG with a thickness greater than A mm is pre-punched on the first glass. When the glasses are laid together, the first glass and the second glass squeeze the redundant thickness of 4SG to A mm and form the first 4SG thermoplastic spacer sealant, that is, the first glass and the second glass are both bonded and sealed with the first 4SG thermoplastic spacer sealant.

DETAILED DESCRIPTION
[0021] In order to provide a further understanding of the purpose, structure, features, and functions of the present invention, the present invention is described in detail below with reference to the embodiments.
[0022] In the description of the present invention, it should be noted that the terms "center", "up", "down", "left", "right", "vertical", "horizontal", "inside", "outside", etc. indicate directions or positional relationships based on the directions or positional relationships shown in the accompanying drawings. They are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction. Therefore, they cannot be understood as limitations on the present invention.
[0023] Please refer to Figure 1 and Figure 2 A long-term sealed built-in sunshade insulating glass comprises a first glass 1, a second glass 2, a louver frame 3, a first 4SG thermoplastic spacer sealant 4, and a first structural adhesive 5; the first glass 1 and the second glass 2 are arranged face to face, and the first 4SG thermoplastic spacer sealant 4 is provided on the peripheral edge between the first glass 1 and the second glass 2. The first glass 1 and the second glass 2 are bonded and sealed by the first 4SG thermoplastic spacer sealant 4 to form a first closed chamber, and the interior of the first closed chamber is filled with inert gas. The louver frame 3 is located in the first closed chamber, and the louver frame 3 is bonded and fixed to the first glass 1 by the first structural adhesive 5, and there is no interaction force between the louver frame 3 and the first 4SG thermoplastic spacer sealant 4.
[0024] The long-term sealed built-in sunshade hollow glass protected by the utility model is different from the traditional built-in sunshade hollow glass in terms of structure and preparation process. Since the current hollow glass production adopts the vertical assembly method, during the preparation process of the long-term sealed built-in sunshade hollow glass of the utility model, a circle of 4SG is first extruded on the first glass 1, at which time the 4SG material is still in an unsolidified state, and then a structural adhesive, such as VHB adhesive, is pasted on the louver frame 3. VHB adhesive is a polyacrylate double-sided foam tape produced by a unique solvent-free manufacturing technology, one side of which is pasted and fixed on the louver frame 3, and the other side is torn off. The worker / mechanical arm holds the louver frame 3 and aligns it and then carefully pastes and fixes it on the designated position of the first glass 1. When the vertical assembly is performed, the first glass 1 can effectively prevent the louver frame 3 from moving after being erected, so that the second glass 2 can smoothly cover and extrude the 4SG, and after solidification, the first 4SG thermoplastic spacer sealant 4 is formed, which bonds and fixes the first glass 1 and the second glass 2 and achieves the functions of sealing and supporting.
[0025] The utility model uses a first 4SG thermoplastic spacing sealant 4 to replace the butyl glue and spacing strips of the traditional louver insulating glass, and can also adopt a sealing system of 4SG+silicone structural adhesive; the 4SG material itself has good support and sealing properties, and also has a certain elasticity. When the gas in the insulating glass is deformed with the change of temperature, the 4SG thermoplastic spacing sealant can be deformed accordingly, thereby maintaining a long-term seal; in addition, the louver frame 3 is bonded and fixed to the first glass 1 using the first structural adhesive 5, and no mutual force is generated between the 4SG thermoplastic spacing sealant on its periphery. During the long-term use of the louver system, it can effectively avoid the edge of the louver frame 3 from applying shear force to the first 4SG thermoplastic spacing sealant 4 for a long time. On the other hand, the 4SG thermoplastic spacing sealant itself has structural bonding strength, and its own shear resistance is also stronger, so that the 4SG thermoplastic spacing sealant of the built-in sunshade insulating glass used for a long time can also always maintain excellent airtightness.
[0026] The utility model uses structural adhesive to bond and fix the louver frame 3 to the first glass 1, and VHB glue can be selected. VHB glue is a double-sided polyacrylate foam tape. The foam core and the adhesive on the surface are all composed of polyacrylate viscoelastics, rather than coating adhesive on both sides of the foam core. This special structure gives the tape a special overall viscoelasticity and has a strong structural bonding strength. It can fix and bond a large louver frame 3 to the first glass 1 for a long time, and it is very convenient to use. After cutting to the required length, one side is bonded to the periphery of the front or back side of the louver frame 3, and the other side is bonded to the first glass 1.
[0027] In one embodiment, the distance between the first glass 1 and the second glass 2 is A mm, then before the glass is laminated, a circle of 4SG with a thickness greater than A mm is pre-punched on the first glass 1. When the glass is laminated, the first glass 1 and the second glass 2 squeeze the redundant thickness of 4SG to A mm and form the first 4SG thermoplastic spacer sealant 4, that is, the first glass 1 and the second glass 2 are both over-bonded and sealed with the first 4SG thermoplastic spacer sealant 4. Preferably, before the glass is laminated, the thickness of the circle of 4SG punched on the first glass 1 is (1+10%)*A mm. In this embodiment, it is ensured that when the first glass 1 and the second glass 2 are vertically laminated, the second glass 2 squeezes the circle of 4SG on the first glass 1, and there is redundant thickness to squeeze and deform the 4SG at the junction with the second glass 2, so as to achieve the purpose of over-bonding, avoid the generation of gaps, and thus ensure the airtightness between the first glass 1 and the second glass 2.
[0028] In one embodiment, the first structural adhesive 5 is adhered to the entire circumference of the louver frame 3 , effectively ensuring the structural bonding strength between the louver frame 3 and the first glass 1 .
[0029] In one embodiment, the edges of the louver frame 3 are all located on the inner side of the first 4SG thermoplastic spacer sealant 4 and do not contact the first 4SG thermoplastic spacer sealant 4, which can effectively prevent the first 4SG thermoplastic spacer sealant 4 from being subjected to the shear force exerted by the louver frame 3, thereby ensuring the long-term sealing of the built-in sunshade insulating glass; in addition, it can also effectively prevent the shape of the unformed 4SG thermoplastic spacer sealant from being destroyed during the installation of the louver frame 3, thereby ensuring that there is no gap between the first 4SG spacer sealant and the second glass 2 after vertical assembly, thereby further ensuring the airtightness of the built-in sunshade insulating glass.
[0030] In one embodiment, please refer to Figure 3The built-in sunshade insulating glass is a three-glass double-chamber structure, and also includes a third glass 6, a magnetic bridge accessory 7, a second 4SG thermoplastic spacer sealant 8, and a second structural adhesive 9; the third glass 6 is relatively arranged on the outside of the first glass 1, and the peripheral edge between the third glass 6 and the second glass 2 is provided with a second 4SG thermoplastic spacer sealant 8, and the third glass 6 and the second glass 2 are bonded and sealed by the second 4SG thermoplastic spacer sealant 8 to form a second closed chamber, and the second closed chamber is filled with inert gas, and the magnetic bridge accessory 7 is bonded and fixed to the second glass 2 by the second structural adhesive 9. The airtight system of the built-in sunshade insulating glass with a three-glass double-chamber structure is essentially the same in both cases, that is, first, a circle of 4SG is made on the glass without other components on the plane, and then the functional accessories, such as the blind accessories and the magnetic bridge accessories 7 are bonded and fixed to the corresponding glass by the structural adhesive, and finally the vertical assembly is performed.
[0031] In a preferred embodiment, the magnetic bridge fitting 7 and the second 4SG thermoplastic spacer sealant 8 do not contact each other, so as to avoid the magnetic bridge fitting 7 generating shear force on the second 4SG thermal spacer sealant, thereby avoiding damage to the airtightness of the insulating glass after long-term use.
[0032] In one embodiment, the distance between the second glass 2 and the third glass 6 is B mm. Before the glass is laminated, a circle of 4SG with a thickness greater than B mm is pre-applied on the second glass 2. When the glass is laminated, the second glass 2 and the third glass 6 squeeze the redundant thickness of 4SG to B mm and form the second 4SG thermoplastic spacer sealant 8, that is, the second glass 2 and the third glass 6 are both bonded and sealed with the second 4SG thermoplastic spacer sealant 8. Preferably, before the second glass 2 and the third glass 6 are laminated, the thickness of the circle of 4SG applied on the second glass 2 is (1+10%)*B mm. When using the 4SG equipment to apply the glue, leaving redundant thickness can ensure that there will be no gaps when the glass is laminated vertically, thereby ensuring the airtightness of the insulating glass.
[0033] In one embodiment, the magnetic bridge fitting 7 is bonded and fixed on the third glass 6, that is, when the built-in sunshade insulating glass is a three-glass double-chamber structure, the first glass 1 and the second glass 2 and the shutter fitting are assembled and joined first, and then the second chamber can be assembled and produced according to the actual production situation, including the following situations:
[0034] First, the magnetic bridge accessory 7 can be fixed on the first glass 1 by the second structural adhesive 9, and then the third glass 6 is combined with the first glass 1; second, the magnetic bridge accessory 7 can be fixed on the second glass 2 by the second structural adhesive 9, and then the third glass 6 is combined with the second glass 2; third, the magnetic bridge accessory 7 can be fixed on the third glass 6 by the second structural adhesive 9, and then the third glass 6 is combined with the first glass 1; fourth, the magnetic bridge accessory 7 can be fixed on the third glass 6 by the second structural adhesive 9, and then the third glass 6 is combined with the second glass 2. Figure 3 The left-view structural schematic diagram of the triple-glass double-cavity built-in sunshade insulating glass in the second case is disclosed, and the schematic diagrams of the triple-glass double-cavity built-in sunshade insulating glass in other cases are not shown.
[0035] In summary, the long-term sealed built-in sunshade insulating glass structure and production process protected by the utility model are simpler, suitable for larger louver insulating glass and can maintain excellent long-term sealing and extend service life.
[0036] The present invention has been described by the above-mentioned relevant embodiments, however, the above-mentioned embodiments are only examples for implementing the present invention. It must be pointed out that the disclosed embodiments do not limit the scope of the present invention. On the contrary, any changes and modifications made without departing from the spirit and scope of the present invention are within the scope of patent protection of the present invention.
