Abstract
The utility model provides toughened vacuum glass which is characterized by comprising a plurality of layers of toughened glass plates, miniature supporters and a sealing structure, wherein the miniature supporters are arranged between the two adjacent glass plates to play a supporting role; and the sealing structure is positioned on the edges of the glass plates to hermetically seal the two adjacent glass plates. An arrangement interval between every two adjacent miniature supporters is 35-60 mm; the glass plates adopt the toughened glass plates; and the sealing structure consists of metal layers fixedly connected with the surfaces of the glass plates and a brazing layer for connecting the metal layers on the two layers of glass plates in a welding manner. The toughened vacuum glass provided by the utility model has the beneficial effect that the number of the miniature supporters used between the two adjacent glass plates is reduced, so that the light transmission of the vacuum glass is better, the impact on sight is reduced, the strength of the vacuum glass is greatly improved, and the use scope of the vacuum glass is enlarged.
Description
Technical field
The utility model relates to a kind of vacuum glass.
Background technology
As shown in Figure 1, at present, the structure of vacuum glass comprises layer glass plate 1, is provided with the miniature upholder 2 of annular/cylindricality between the layer glass plate, and the edge of layer glass plate 1 is through the low glass powder sealing-in.Earlier low glass powder is placed during sealing-in and treat the sealing-in position, get into process furnace then and glass is heated the layer glass plate is sealed in the low glass powder fusing.Because the temperature of fusion of low glass powder will be higher than the tempering temperature of toughened glass, in heat-processed, can make toughened glass annealing.So vacuum glass of the prior art uses the simple glass manufacturing usually.Because vacuum glass inside is vacuum; Needing that 2 pairs of sheet glass of some miniature upholders are set between the layer glass plate supports; Density is set should confirms of miniature upholder 2 according to sheet thickness and sheet glass intensity, distance is too little, then influences the light transmission of glass; Excessive then sheet glass can't bear miniature upholder 2 its reactive force that applies is broken.Be spaced apart 25mm between the miniature upholder 2 that is provided with in the present vacuum glass, it is bigger that miniature upholder 2 is provided with density, influences sight line.And owing to use simple glass to make vacuum glass, its security is relatively poor, can't use in many outdoor occasions, and the range of application of vacuum glass is very limited.
The utility model content
To the existing problem of vacuum glass in the prior art; The utility model provides a kind of vacuum glass that uses toughened glass to process, because toughened glass intensity is higher much than simple glass, so reduce the density that is provided with of the miniature upholder of portion within it; So not only reduced because the reduction of the glass heat-proof performance that upholder conduction heat causes; The minimizing of upholder quantity has improved the glass heat-proof performance, and has improved the intensity of vacuum glass greatly, has enlarged the use range of vacuum glass.
A kind of toughened vacuum glass; Comprise the several layers armourplate glass, be arranged in twos between the adjacent sheets of glass passive miniature upholder and be positioned at the sealing structure of glass plate edge the airtight sealing-in of adjacent sheets of glass in twos; The spacing that is provided with of said miniature upholder is 35-60mm; Said sheet glass is an armourplate glass, and said sealing structure is made up of metal level that is cemented in glass pane surface and brazing layer that the metal level on the layer glass plate is welded to connect.
Further, said miniature upholder is spherical.
Further, the above support material is metal, glass, pottery, glass glaze etc.
Further, said metal level is made up of tinsel, this tinsel through the supersonic welding solid welding in glass pane surface.
Further, said metal level is made up of metal layer, and this metal layer is formed behind sintering by the metal paste that is coated in glass pane surface.
Further, said metal layer has the thermal expansivity close with sheet glass.
The utility model is through being provided with metal level in sheet glass sealing-in place in advance, and through braze toughened glass carried out Vacuum Package, and the fusing point of braze is lower than the annealing temperature of toughened glass; Guaranteed that in process of production toughened glass can not anneal in encapsulation process; Keeping the intensity of toughened glass, and reduce the consumption of miniature upholder between the sheet glass thus, improved the heat-proof quality of glass; Make the light transmission of vacuum glass better simultaneously; Influence reduces to sight line, and has improved the intensity of vacuum glass greatly, has enlarged the use range of vacuum glass.

Embodiment
As shown in Figure 2, the toughened vacuum glass in the utility model comprises layer glass plate 1, miniature upholder 2 and sealing-in thing 3.Wherein, layer glass plate 1 is toughened glass; Miniature upholder 2 is arranged between the layer glass plate 1, and sheet glass is played a supporting role; Sealing-in thing 3 is arranged between the layer glass plate, is positioned at sealing-in place of sheet glass, and the layer glass plate is carried out sealing-in, makes between the layer glass plate and realizes hermetic seal between the space and ambient atmosphere, guarantees the vacuum tightness between the layer glass plate.Because the bearing stress that armourplate glass can bear is more than 90MPa; So the spacing that is arranged between the miniature upholder between the layer glass plate can suitably increase; Draw through Theoretical Calculation and actual experiment; The spacing that is provided with between the adjacent miniature upholder is 35 ~ 60mm, and can suitably adjust according to the thickness of armourplate glass.Miniature upholder 2 has adopted the coccoid of being convenient to make; And; Contacting to point contacts between spherical upholder and the sheet glass 1 is significantly less than the annular/columnar supports that present vacuum glass adopts and the contact area of sheet glass 1, and the heat-proof quality of vacuum glass is improved greatly.The material of miniature upholder 2 can be metal, glass, pottery, glass glaze etc.As shown in Figure 3, sealing-in place of sheet glass is along the edge setting of layer glass plate.Sealing-in thing 3 comprises the metal level of firing in advance on the layer glass plate 31 and is arranged on the brazing solder 32 between the metal level.Metal level 31 is to apply in advance and the sintering metal level close with expansion coefficient of glass thread, and this metal level is Ag or Cu-Ag alloy usually; The method that initialization layer applies can be carried out through modes such as craft, machinery, dip-coating, spraying or silk screen printings.And can be in the process of glass being carried out tempering above-mentioned metal level be sintered to simultaneously and treats the sealing-in position.Brazing solder 32 is arranged between the metal level of lower glass substrate; Its material is preferably tinsolder, and its advantage is that welding temperature is low, is no more than 250 ℃.Soldering is normally accomplished in braze chamber, and soldering is normally charging into H
2Gas and N
2Carry out under gas or other protection of inert gas environment; Temperature generally is no more than 350 ℃, to guarantee that the glass behind the tempering can not annealed in the process of soldering.The consumption of brazing solder should be adjusted according to the size in gap, and is tight more, firm with the face of weld that guarantees sheet glass.After welding, the vacuum glass after compound is carried out finishing of limit portion and packing.
In addition, the mode of welding also can be that the weld is carried out local heating, as: modes such as induction heating, flame heating, current flow heats, LASER HEATING, microwave heating, immersed solder technology.
