[0022] The specific embodiments of the utility model are further described in detail by comparing the drawings and describing the embodiments.
[0023] For example, Figs. 1 to 4As shown, the low-radiation coated interlayer energy-saving glass comprises outer glass 1, intermediate layer glass 2 and inner glass 3, the intermediate layer glass is arranged between the outer glass and the inner glass; the intermediate layer glass is a laminated glass structure, the laminated glass structure comprises two or more low-radiation coated glasses and a rubber sheet arranged between the low-radiation coated glasses; the edge portion of the laminated glass structure is located inside the edge portion of the outer glass and the inner glass to form an edge portion concave structure, and a sealing glue structure is arranged in the concave structure.
[0024] The laminated glass structure is directly attached to the outer glass and the inner glass; the rubber sheet is an SGP rubber sheet or a PVB rubber sheet. When the total thickness of the laminated product is the same or the total thickness of the laminated glass is reduced, by changing the number of laminated glass layers, the two glass layers are changed into three glass layers, and by using the bonding performance and tensile resistance of the SGP or PVB interlayer material of the laminated glass, the wind pressure resistance, impact resistance, sound insulation and bulletproof effect of the laminated glass are improved, the function and strength of the laminated glass are enhanced, and the energy-saving effect of the product is improved.
[0025] The laminated glass structure comprises two low-radiation coated glasses, and the rubber sheet is combined between the two low-radiation coated glasses; the laminated glass structure is a laminated glass assembly produced by pressing.
[0026] The size of the laminated glass structure is 10-30mm smaller than the size of the outer glass and the inner glass, and the edge portion of the overall energy-saving glass forms a concave shape; the sealing glue structure comprises a first coating of butyl glue and a second injection of structural glue or polysulfide glue, and the sealing is reliable.
[0027] The utility model discloses a three-layer glass (or three-layer upper layer) laminated glass structure, which utilizes the size difference between large and small pieces of glass and differentiates the large and small pieces of glass to be positioned and combined by the edge positioning equipment, realizes consistent edge floating of the large and small pieces of glass, and produces a laminated product, and the laminated product is produced by high-pressure after initial pressing.
[0028] The three-layer glass laminated glass or three-layer or more glass laminated product uses low-radiation coated glass in the intermediate layer, which can adopt two structure modes of tempered or non-tempered process, or two or more low-radiation coated glass combinations. When the non-tempered low-radiation coated glass is adopted, (the non-tempered LOW-E glass is used in the intermediate layer of the laminated glass), the problems of light distortion and glass curtain wall image imaging difference and serious light reflection pollution of vision caused by the decrease of flatness of the low-radiation coated glass due to tempering or poor tempering process can be better improved.
[0029] When the total thickness of the interlayer product is the same or the total thickness of the interlayer glass is reduced, the wind pressure resistance, impact resistance, sound insulation and bulletproof effect of the interlayer glass are improved by changing the number of interlayer glass layers and using the bonding performance and tensile resistance of the interlayer material SGP or PVB in the interlayer glass. After changing the two-layer glass interlayer product to a three-layer glass interlayer, the original two-layer interlayer configuration strength is not reduced (such as 8+8 interlayer to 6+5+5 or 8+4+4 or 6+4+4 configuration, the total glass thickness is 16mm or less than 16mm, and the application of low-e glass also improves the interlayer glass decoration effect, energy saving effect, and enhances the wind pressure resistance, impact resistance, sound insulation and heat insulation performance, and bulletproof function of the interlayer glass.
[0030] Without using the LOW-E glass film removal process, the edge bonding performance of the interlayer glass is better improved, and the adhesive bonding force caused by the film removal process is reduced. When producing, the LOWE low-emission coated glass sheet (small piece) is combined in the interlayer of the interlayer glass. When using two or more pieces of LOW-E glass for multi-layer interlayer glass, the LOW-E glass film surface is towards the indoor surface or outdoor surface, or the two film glass film surfaces are opposite or towards or opposite direction (according to the product structure design needs) for combination and gluing, so that the film layer of the coated glass is completely covered in the interlayer of the interlayer glass, and the LOW-E glass film surface is not exposed to the air.
[0031] The edge interlayer coated glass of the interlayer glass is completely sealed, which ensures that the interlayer low-emission coated glass and the surrounding part are not in contact with the outside air, and solves the possibility of oxidation or delamination of the interlayer low-emission coated glass due to exposure to air. It can also better bond the four surrounding edges of the interlayer glass with the filling sealant, avoid the problem of edge bubbles and delamination of the interlayer glass edge over time, and better ensure the performance of the finished product glass.
[0032] When producing the interlayer glass, the size of the split glass is used to cut the interlayer low-emission glass layer, and the size of the glass is small. The size of the small piece is generally based on the depth of the sealant, which realizes the production requirements of uniform edge of the interlayer glass inside and outside the sheet, and generally reduces the size of the interlayer glass by 10-30mm. When the interlayer is combined, the interlayer (the second layer and the third layer) glass is uniformly left with a floating edge of about 5-15mm around the four edges of the first glass and the third glass (or the fourth glass) (the amount of each edge can be determined according to the actual use and design requirements of the customer, and the edge sealing requirement cannot be lower than 5mm in general). The floating edge effect is combined, and then high pressure is applied.
[0033] The interlayer of the laminated glass is bonded by high pressure using high-quality PVB (or soundproof film) or SGP material to enhance the compression resistance, sound insulation, and bulletproof performance of the glass. The edge of the interlayer of the laminated glass does not need to be treated to remove the film, so the film surface of the LOW-E glass is not damaged, the integrity of the LOW-E film of the coated glass is maintained, the bonding performance between the interlayers of the laminated glass is better ensured, and the aesthetic appearance of the laminated product is enhanced.
[0034] After the glass is subjected to high pressure, the residual PVB film on the edge of the glass is removed. A handheld butyl rubber coating machine is used to coat the first layer of butyl rubber with excellent sealing performance at the chamfered joint of the interlayer of the laminated glass. The handheld butyl rubber coating machine is used to coat the second layer of structural adhesive or polysulfide adhesive in the groove around the edge of the laminated glass. The edge of the interlayer of the laminated glass is fully sealed, and an automatic adhesive injection machine is used to ensure that the interlayer of the laminated glass does not come into contact with the outside space, thereby preventing the oxidation or delamination of the interlayer of the laminated glass. The four edges of the laminated glass are fully bonded by the filling and sealing adhesive, which prevents the generation of bubbles and delamination at the edges of the laminated glass over time, and ensures the performance of the finished product.
[0035] When the LOW-E coated glass is ground, the chamfered edge of the film is at least 2mm or more to ensure that the film surface of the LOW-E glass is fully bonded after laminating, and the first layer of butyl rubber coating is better sealed.
[0036] The laminated product structure combination of heat-reflecting glass or silver-free glass and LOW-E glass can be used according to the actual needs of the customer. The film surface of the heat-reflecting glass can be directed towards the indoor surface or the outdoor surface, and the film surface of the interlayer of the LOW-E glass can also be directed towards the indoor surface or the outdoor surface for laminating production, thereby realizing a high-performance new green laminated glass product with shading and energy-saving effects, making the product color and function more complete and diversified, and meeting the requirements of individualization, decoration effect, and energy-saving effect.
[0037] When non-tempered coated glass is used as the interlayer of the laminated combination of the LOW-E coated glass, the four edges of the coated glass are used to fill the sealing adhesive, which better protects the edges of the non-tempered coated glass from being damaged due to uneven stress during installation and use, and ensures that the interlayer of the non-tempered coated glass is not damaged.
[0038] The utility model discloses a low radiation energy-saving sandwich glass of three-layer glass: the middle layer glass (second layer glass) adopts low radiation coated glass, and the size of the glass is 10-30mm smaller than the general cutting size of the outer piece (first layer) and the inner piece glass (third layer) glass, when the three-layer glass sandwich is combined, the four edges of the middle layer (second layer) glass are 5-15mm smaller than the four edges of the inner and outer piece glass, and the four edges are uniformly reserved, the effect of the four edges of the middle layer is realized during the base layer production, after the high pressure of the sandwich, the excess residual film of the edge is removed, the small piece glass between the inner and outer piece glass is sealed by using the sealant, the edge of the LOW-E glass between the sandwich glass is all sealed in the sealant, and the glass can be installed and used independently after the solidification of the sealant. Before the sealant injection of the sealant, a butyl sealant is added to the four edges (film surface edge) of the LOW-E glass, and the sealant is sealed again, so that the sealing effect is better, and the service cycle performance is better.
[0039] The scheme can make the low radiation coated glass fully applied and used in the field of sandwich glass, make the coated sandwich product structure more diversified, meet the separate use requirement of the LOW-E sandwich product, realize the high-performance sandwich glass product with the sun-shading and energy-saving performance, realize the multifunctional sun-shading and energy-saving combined new energy-saving sandwich product combined with the heat reflection and low radiation coated glass and the silver-free glass and independently used, and improve the application of the coated glass in the field of sandwich product and the decoration effect of the coated sandwich glass.

[0041] The utility model is described above in connection with the drawings, and obviously, the specific implementation of the utility model is not limited by the above mode, as long as various non-essential improvements are made by adopting the concept and technical scheme of the utility model, or the concept and technical scheme of the utility model is directly applied to other occasions without improvement, and all falls within the protection scope of the utility model.
