In order to effectively improve the mechanical properties and the carrying capacity of the hollow glass on the premise of improving the sealing performance, the utility model proposes a hollow glass, fig. 1 is a front view of the hollow glass in an embodiment of the utility model, fig. 2 is a cross-sectional view of the hollow glass in an embodiment of the utility model, fig. 3 is a partial enlarged view of B in fig. 2 in a first embodiment, fig. 4 is a partial enlarged view of B in fig. 2 in a second embodiment, as shown in fig. 1 to 4, and the hollow glass may include: a first layer of glass 1; a second layer of glass 2; a first spacer 3 and a second spacer 4 arranged between the first layer 1 and the second layer 2 of glass.
Wherein, the first layer glass 1 and the second layer glass 2 are arranged in parallel, and a certain gap is arranged between the first layer glass 1 and the second layer glass 2 to set a first spacing bar 3 and a second spacing bar 4.
The first spacing bar 3 and the second spacing bar 4 form a sealing cavity 5 between the first layer glass 1 and the second layer glass 2, and the sealing cavity 5 is separated from the outside through the first spacing bar 3 positioned on the inner side and the second spacing bar 4 positioned on the outer side.
As shown in fig. 3 and 4, at least one of the first spacer 3 and the second spacer 4 is made of a metal material, the first spacer 3 is sealed with the first layer glass 1 and the second layer glass 2 by using a first sealant 6, and the second spacer 4 is sealed with the first layer glass 1 and the second layer glass 2 by using a second sealant 7.
The hollow glass separates the sealing cavity 5 from the outside through the first spacing bar 3 with the first sealing glue 6 and the second spacing bar 4 with the second sealing glue 7, so that the sealing effect of the whole hollow glass can be greatly improved, the water permeability is reduced, and the possibility of fog generation in the sealing cavity 5 after long-term use can be greatly reduced. In addition, at least one of the first spacing bar 3 and the second spacing bar 4 is made of metal material, so that the mechanical property of the whole hollow glass can be greatly improved by utilizing the mechanical characteristics of the spacing bar made of metal material, and the load resistance can be effectively improved. Finally, the spacer made of metal material can greatly improve the fireproof capability of the hollow glass, not only can keep the hollow glass not deformed when a fire disaster occurs, but also has fireproof effect, and can reduce the amount of toxic gas generated by the organic material when the fire disaster occurs.
In some embodiments, the first spacer 3 may be a warm-edge spacer made of a low thermal conductivity material, which may be used to reduce the thermal conduction of the hollow glass edge. The warm-edge spacer may include a rigid warm-edge spacer and a flexible warm-edge spacer.
In some embodiments, when the warm-side spacer comprises a rigid warm-side spacer, for example, the first spacer 3 may be made of polypropylene + stainless steel, or of PVC + stainless steel, or of fiberglass reinforced composite + composite film, or the like. When the warm-side spacer comprises a flexible warm-side spacer, the first spacer 3 may be made of polyisobutylene or a micro-porous elastic thermosetting integrated material using silicone as a base material.
In some embodiments, the first spacer 3 may also be made of a metal material, which has a certain high strength. For example, the metal material having a certain high strength may include aluminum, stainless steel, and the like.
In some embodiments, as shown in fig. 3 and 4, the first spacer 3 may have a hollow structure, and the first spacer 3 is filled with a desiccant 9. The first spacer 3 is provided with a communication hole 31 communicating with the inside of the first spacer itself and the seal chamber 5. The desiccant 9 may be used to dehumidify the sealed chamber 5 to ensure desiccation of the gas in the sealed chamber 5, further reducing the likelihood of fogging in the sealed chamber 5. For example, the desiccant 9 may use, but is not limited to, one or more of the following: silica gel, activated alumina, silica alumina gel, 3A molecular sieves, silica gel 3A molecular sieve mixtures, and 3A molecular sieve sealant combinations, and the like. The silica gel 3A molecular sieve mixture specifically uses silica sol as a dispersing agent and an adhesive to generate a high-performance silica gel and molecular sieve compound. The 3A molecular sieve sealant combination is a high molecular material elastomer, combines the molecular sieve and the sealant together, has certain rigidity and supporting function, and also has good sealing and water absorption performances.
In some embodiments, the second spacer 4 may be a spacer made of a metal material, which has a certain high strength. For example, the metal material having a certain high strength may include aluminum, stainless steel, and the like. Or the second spacer 4 may be a warm-side spacer.
In some embodiments, as shown in fig. 3 and 4, the second spacer 4 may have a hollow structure to improve the heat insulating property of the second spacer 4. The second spacer 4 may not be filled with a desiccant 9. The two spacing bars cannot be communicated with the sealing cavity 5, so that the usage amount of the drying agent 9 can be greatly reduced, and the aim of saving cost is achieved.
In some embodiments, one of the first and second sealants 6 and 7 may employ a sealant having a low water permeability. The sealant can only meet the requirement that the water vapor transmittance is less than or equal to 0.8 g/(m 2.d). For example, butyl hot melt sealants, polyisobutylene, and the like, which meet the above requirements. The main function of the sealant is to reduce the water vapor permeation of the edge area of the hollow glass. For example, when the sealant is a butyl hot melt sealant, its thickness may be between 0.2mm and 0.6mm, and its width in the direction of the seal cavity 5 toward the second spacer 4 may be 3mm or more to have sufficient performance of preventing infiltration of moisture, and further, may be 5mm or less to avoid waste of materials.
In some embodiments, the other of the first sealant 6 and the second sealant 7 may employ a sealant satisfying excellent weather resistance and structural mechanics. The sealant may be silicone adhesive. The silicone adhesive is an elastic material formed by taking hydroxyl-terminated polydimethylsiloxane as a base polymer, adding a cross-linking agent, a reinforcing filler and other auxiliary agents, and vulcanizing. Compared with other sealants (such as polyurethane, acrylic acid, polysulfide sealant and the like), the silicone sealant has better ultraviolet light resistance and atmospheric aging resistance due to larger Si-O bond energy in a molecular structure, can keep 30 years of no cracking and no deterioration, has the deformation displacement resistance of +/-50% in a wider temperature range, has the tensile bonding strength of less than or equal to 0.45MPa (after water-ultraviolet irradiation), and has the thermal weight loss of less than or equal to 6%. The silicone sealant may be classified into at least 7 types of deacidification type, ketoxime type, dealcoholization type, deamidation type, acetone type, hydroxylamine type, amine type, and the like according to the type of by-product generated by the condensation reaction of the crosslinking agent with the hydroxyl-terminated polydimethylsiloxane.
When one of the first sealant 6 and the second sealant 7 adopts the sealant with low water permeability and the other adopts the sealant with good weather resistance and structural mechanics, a large amount of expensive sealant with good weather resistance and structural mechanics can be saved, and the aim of saving cost is achieved.
In some embodiments, as shown in fig. 4, a third sealant 8 is filled between the outer side of the second spacer 4 and the first layer glass 1 and the opposite sides of the first layer glass 1. The sealing cavity 5 and the outside are required to be separated by the first sealing glue 6, the second sealing glue 7 and the third sealing glue 8 in sequence. The third sealant 8 can have weather resistance, ageing resistance, structural mechanical properties and sealing properties, fully ensures the mechanical properties between the first layer glass 1 and the second layer glass 2, and plays a role in preventing moisture from entering through long-term sealing.
In some embodiments, the third sealant 8 may be one of the following materials: silicone gums, polysulfide gums, silane modified polyether gums, polyurethane gums, and the like.
In some embodiments, the first spacer 3 and the second spacer 4 may be made of a metal material, which may have a certain high strength. Therefore, the mechanical characteristics of the two spacing bars can be improved to the maximum, the mechanical property of the whole hollow glass can be improved, and the load resistance can be improved greatly.
