Description
Technical field
The present invention relates to the processing and manufacturing of vacuum glass, making method of especially a kind of vacuum glass and products thereof.
Background technology
Vacuum glass is a kind of novel energy-conserving, environmentfriendly products, can be widely used in the industrial or agricultural fields such as building window, glass curtain wall, solar product, agricultural greenhouse, refrigerator and refrigerator and the resident's daily living article, be good heat insulation, sound insulation and finishing material.In the making processes of vacuum glass, the structure of edge sealing-in and technology be guarantee that circumference of vacuum glass is indeformable, do not produce the stress that exceeds standard, air tight and keep the gordian technique of toughened glass characteristic.During patent CN94192667.2 " makes the method for vacuum glazing ", edge packing structure is designed to that upper glass is slightly less than lower-glass in two blocks of glass, the low melting glass scolder places on the edge step of two glass formation, glass solder after the fusing is because capillarity flows into two glass gaps, the method is the present edge sealing technology of the most representative and tool practicality, but has the shortcoming that the scolder consumption is large, the edge is uneven, stress is larger; Among patent CN95108228.0 " vacuum flat glass and manufacture method thereof " and the CN96208977.X " vacuum flat glass ", adopt in advance " chamfering " processing of glass plate edge, scolder is placed in the chamfering groove, and the method exists the large and low melting glass scolder of cloth difficulty adding when heat-sealable the easily deficiency of loss; Patent CN02256440.3 " edge packing structure of vacuum glass " is that periphery is put the loss that helps strip of paper used for sealing to stop scolder liquid on lower sheet glass, although the method has solved the problem of the outside loss of scolder liquid, but complex process, help strip of paper used for sealing to take larger space, can not solve the problem that scolder liquid flows to inside glass; The edge bonding method of the vacuum glass that patent CN200620070302.7 " Whole transparent vacuum glass " proposes is to make with glass or make edge band through surface treatment at glass edge, and its shortcoming is that not only cost of manufacture is high nor can limit solder and flow to inside glass for edge band; Patent CN200920314752.X " edge sealing structure of vacuum glass " is that upper sheet glass and/or the substrate glass between upper sheet glass and substrate glass edge is shaped with the geometric form packing groove, although can improve lock packing tack between the sheet glass on substrate glass reaches, but the packing groove of upper lower-glass is difficult to fill up simultaneously lock packing, nor can limit arbitrarily flowing of lock packing; Patent CN201010228110.5 " a kind of method for sealing edge of vacuum glass " puts the glass welding material at vacuum glass raw sheet periphery, the interior impervious barrier that one deck is made of powdery or fibrous material is set in the inboard of glass welding material, it is inner that restriction glass solder liquid flows into vacuum glass, compared with prior art, the method only is to have limited glass solder liquid to flow into vacuum glass inside, fails to overcome other shortcomings.To sum up the main weak point of existing edge bonding method is: the one, and structure and complex process are not suitable for mechanize, automatization and mass production; The 2nd, the difficulty of bleeding in the edge sealing process, need at the bleeding point that arranges on glass, be not suitable for directly bleeding from the limit section of glass.
The present patent application people arranges the edge band frame at the glass periphery weld and has overcome main drawback in the existing vacuum glass edge sealing technique applying for a patent in 2012100754353 to utilize, but the etch process of its weak point first edge sealing groove not only is unfavorable for workman's physical and mental health, also is unfavorable for environment protection; It two is that the edge band frame needs certain height, cause up and down the vacuum layer thickness between two blocks of glass larger, for the vacuum glass that upholder is arranged, the diameter of its upholder and height will be larger, not only upholder is high-visible but also can transmit more heat and sound, thereby affects visual and heat insulation and the sound-proofing properties of vacuum glass.
Existing vacuum glass generally adopts first high temperature edge sealing, vacuumizes, seals at last the multistep production technique of bleeding point, and vacuumizes, seals bleeding point and be mostly that monolithic carries out.
Existing used its sealing temperature of low temperature glass solder of vacuum glass edge sealing generally is not less than 400 ℃, long-time heating glass under this sealing temperature, can make toughened glass occur to anneal phenomenon and become simple glass, so existing production technology is difficult to produce toughened vacuum glass.
