Description
Technical field
The present invention relates to glass post-processing technical field, particularly relate to a kind of microwave joining seal strip groove edge sealing plane toughened vacuum glass having getter and preparation method thereof.
Background technology
Vacuum glass is a kind of novel energy-saving glass, and vacuum glass not only can solve " breathing " problem of the double glazing of existing a large amount of use, and has that heat-and sound-insulating performance is good, wind pressure resistant strength is high, thickness is little and the advantage such as long service life.Vacuum glass is generally made up of two to three sheet glass, and form cavity between two adjacent sheet glass, the periphery of glass is provided with edge sealing structure, cavity forms vacuum layer after being pumped into vacuum.Vacuum glass is different according to the mode forming vacuum layer, can be divided into two kinds, a kind of is vacuum glass without bleeding point, and the edge sealing of this vacuum glass carries out in vacuum oven, along with completing of edge sealing, between two adjacent sheet glass the cavity self-assembling formation vacuum layer closed; Another kind is the vacuum glass having bleeding point, the edge sealing of this vacuum glass carries out in High Temperature Furnaces Heating Apparatus at ambient pressure, after edge sealing completes again by prefabricated bleeding point between glass the cavity closed vacuumize, finally terminate rear enclosed bleeding point bleeding, complete the making of vacuum glass.
A series of vacuum glass without bleeding point and preparation method thereof is disclosed in the patent of the vacuum glass that present invention applicant applied in October, 2012, but when utilizing low temperature glass solder edge sealing, because low temperature glass solder is made up of many oxide, at high temperature, under vacuum, the air of solder wettable and moisture, volatile substances in solder, in the gas that solder dissolves in process of production and solder, the decomposition etc. of partial oxide all can cause in solder and produce a large amount of bubbles, greatly weaken the properties especially resistance to air loss of solder, the feasibility of this kind of mode is caused to be greatly affected.The vacuum glass of existing mass production is all the vacuum glass having bleeding point, but there is complex manufacturing technology, extraction temperature low (bleeding not thorough), monolithic vacuumizes, cost is high, production capacity is low, can not make the shortcomings such as toughened vacuum glass.In addition, it is larger that the sealed strip utilizing cryogenic glass powder or low temperature glass solder to make and upholder reach required its difficulty of height, its reason one is that glass is non-hygroscopic, be difficult to make highly higher sealed strip and upholder, two sealed strips when being glass temperings and upholder at high temperature melts, it reduces highly further.

9. the plane toughened vacuum glass according to any one of claim 1 to 7, forward stacks when it is characterized in that described upper glass and described lower-glass close sheet, its deformation is matched.
10. the making method of the plane toughened vacuum glass described in any one of claim 1 to 9, is characterized in that comprising the following steps:
The first step, according to the shape of the vacuum glass of required making and two pieces of flat glasss up and down of size cutting desired size, bleeding point is made in the edge punching of upper glass, the sealed groove concentric with bleeding point is made at the upper surface of upper glass, paint metals slurry in sealed groove, according to the size of sealed groove, make a sealing cover, the edge of sealing cover can be inserted in sealed groove; Offer sealing groove at the periphery weld of lower-glass, and edging, chamfering, cleaning and drying treatment are carried out to upper and lower two blocks of glass;
Second step, prepares sealed strip at the periphery of upper glass and the periphery of sealing groove, and the sealed strip of upper glass can insert in corresponding sealing groove, and makes upholder at least one block of glass, upper glass, lower-glass is sent in annealing furnace and carries out tempering process subsequently;
3rd step, selects suitable polymer monomer, first monomer whose is become the performed polymer of setting viscosity through preliminary polymerization, is then produced on toughened glass ink or upper lower-glass by performed polymer by printing, printing or the mode of mechanically spraying; Performed polymer can at room temperature be solidified into elastomerics, elastomerics by catalyzer in vacuum glass edge sealing process, be heated to the irregular change that elastomeric state adapts to vacuum layer height automatically before glass closes sheet; Performed polymer also automatically can adapt to after glass closes sheet vacuum layer height irregular change, again by hot setting elastomer-forming;
4th step, by even spread low temperature glass solder in the sealing groove of lower-glass periphery, upper and lower glass is sent in microwave oven after closing sheet;
5th step, carries out heat temperature raising operation to described microwave oven, is warming up to more than the melt temperature of low temperature glass solder, reaches edge sealing temperature, and the sealed strip of upper glass is under the action of gravity of glass in embedding sealing groove; Stop heating, with stove cooling, two blocks of glass hermetic weld together by low temperature glass solder, and the fire door opening microwave oven obtains double glazing;
6th step, puts into getter bleeding point, covers sealing cover, then brazing metal is put on sealed groove or sealing cover, and sends in vacuum oven; Described vacuum sole is vacuumized, limit heating, be evacuated to below 0.1Pa, be warming up to more than the temperature of fusion of brazing metal, getter automatic activation under high temperature, high vacuum, brazing metal is also fused into liquid; Liquid retention is in sealed groove, and the edge of sealing cover is also flooded in a liquid, and liquid is by bleeding point self-sealing, and getter is also sealed in vacuum layer; Stop heating, with stove cooling, brazing metal solidifies and realizes airtight sealing to bleeding point afterwards, opens vacuum oven, takes out vacuum glass;
7th step, puts into seal gum in the bleeding point of vacuum glass, Paste Product trade mark or metal decorative sheet on seal gum.
