Description
Technical field
The present invention relates to a kind of method utilizing glass powder to be encapsulated by vacuum glass.
Background technology
Vacuum glass is by airtight for two panels sheet glass surrounding, its gap is evacuated and seal vents, gap between two panels glass is 0.1-0.2mm, the two panels of vacuum glass generally has at least a slice to be low emissivity glass, so just dropping to minimum by the heat scattered and disappeared by the conduction of vacuum glass, convection current and radiation mode, its principle of work is identical with the heat insulating principle of glass vacuum-bottle. Vacuum glass is glasswork and Materials science, vacuum technique, physical measurement techniques, industrial automation and architecture science etc., the outstanding achievement of multiple subject, multiple technologies, kinds of processes cooperate.
Vacuum glass is a kind of novel energy-conserving glass, and it is based on vacuum flask principle, two panels glass surrounding is sealed, and midfeather is the thin vacuum layer of 0.1-0.2mm. Owing to not having gas heat-transfer, internal surface has had again the transparent low-radiation film of vacuum flask silverskin effect, makes the thermal and insulating performance of vacuum glass be much better than " hollow " glass widely used at present.
But, vacuum glass is being manufactured in process, the seal degree of its encapsulation, determining the height of its performance perameter, in existing market, many simply to adopt seal gum to carry out hermetically sealed for major part vacuum glass, encapsulates insecure, the sealing effect of encapsulation is general, long-time use after, there will be poorly sealed situation, affect vacuum glass work-ing life.
To this, the current domestic following patent documentation of main existence:
Such as patent publication No.: 104291662A, disclose a kind of glass solder welding, groove edge sealing plane toughened vacuum glass be made up of upper glass and lower-glass, it is characterized in that the periphery of upper glass has edge sealing bar frame, the periphery of lower-glass has edge sealing groove, the periphery of upper glass and lower-glass is welded together by glass solder, a closed vacuum layer is formed between upper glass and lower-glass, having upholder in vacuum layer, upholder has one layer or two layers; Edge sealing bar frame and upholder are made up of toughened glass ink and superpolymer compound, superpolymer first makes performed polymer, again performed polymer is prepared on toughened glass ink after glass tempering, last performed polymer is solidified into elastomerics at ambient temperature or elevated temperature, performed polymer or elastomerics can adapt to the change of vacuum layer height automatically, and elastomerics gets rid of the volatile gases contained by self under high temperature, high vacuum; The method of the present invention is easy to realize mechanize, automatic production, it is possible to the toughened vacuum glass of big batch making high-performance, low cost. But, the packaged material that this patent provides is toughened glass ink and/or superpolymer, and superpolymer first makes performed polymer, but only relies on superpolymer to realize sealing, and its sealing effect remains to be discussed.
And for vacuum glass encapsulation glass powder, the current domestic following patent documentation of main existence:
Patent publication No.: CN102515534A, discloses a kind of glass-encapsulated colloidal sol and preparation method and glass encapsulation method and vacuum glass thereof; This glass-encapsulated colloidal sol contains Pb simple substance or Pb compound, and its preparation method, comprising: step S1: measure glass powder with low melting point; Step S2: configure the first solvent; Step S3: configuration the 2nd solvent; Step S4: configuration the 3rd solvent; Step S5: described glass powder with low melting point is mixed with the first solvent, the 2nd solvent and the 2nd solvent. This vacuum glass comprises the first substrate of glass and the 2nd substrate of glass; First substrate of glass and the 2nd substrate of glass are packaged as a whole by above-mentioned glass-encapsulated colloidal sol, are provided with vacuum cavity between the first substrate of glass and the 2nd substrate of glass. This glass encapsulation method is apply above-mentioned glass-encapsulated colloidal sol along the first substrate of glass outer, and arranges upholder thereon, is then pressed afterwards by the first substrate of glass, dries, has vacuumized. The present invention has colloidal sol good uniformity, and resistance to air loss is good, the advantage that bond strength is high. But, in the glass-encapsulated colloidal sol that this patent provides, containing plumbous, this kind of material all can impact to environment and to production, user.
