Vacuum glass has been obtained very big progress through the research and development of last 100 years, theoretical research and measuring to vacuum glass are verified, vacuum glass is desirable heat insulation, sound insulation materials, can do the door and window of building, also can be used to be incubated cabinet, refrigerator or refrigerator.Need aspect many to improve but on industrial production, also have, for example, peripheral sealing technology.
The manufacturing of vacuum glass generally includes following steps: preliminary treatment → breaker prop → peripheral sealing-in → vacuumize → seal.Wherein, peripheral sealing-in operation adopts burning-on method usually, glass powder with low melting point is placed in the gap of two glass plates, and fusion at high temperature and glass stick together, and play sealing function.The shortcoming of this method is:
1, adopt the direct sealing-in of glass powder with low melting point, because sealing surface is the plane, makes the vacuum glass effective area reduce, thereby reduce vacuum chamber volume that vacuum chamber volume is more little, vacuum descends obvious more, causes the vacuum glass lost of life.
If between 2 two blocks of glass too many glass powder with low melting point is arranged, glass dust can not flow out from the space fully, make limit portion seal process at the middle and upper levels glass drop on the pillar, when causing finally realizing vacuum, in near the portion of limit the glass big tensile stress is arranged, mechanical strength is less.
3, because the glass powder with low melting point sealing surface is the plane, increased the gas leakage probability, the yield rate of vacuum glass and life-span are reduced.
Summary of the invention:

The objective of the invention is to be achieved through the following technical solutions:
A kind of peripheral sealing-in device of high heat insulation, high sound insulation vacuum glass, glass plate periphery are sticked that the inboard scribbles glass powder with low melting point and by the rim member of the vertical sealing-in of glass powder with low melting point around the glass plate.
Rim member is a metal frame, and metal frame is provided with the button edge of interior button parcel glass plate periphery.
For metal frame is combined better with glass, metal frame should be the coefficient of expansion alloy material close with glass, for example, and teleoseal, wherein, iron content (Fe) 48 ∽ 52%, nickel (Ni) 42 ∽ 47%, cobalt (Co) 5 ∽ 6%.
When described teleoseal is the 4J6 teleoseal, iron content (Fe) 52%, nickel (Ni) 42%, cobalt (Co) 6%; When described teleoseal is the NRS-2 teleoseal, iron content (Fe) 48%, nickel (Ni) 47%, cobalt (Co) 5%.
Method of the present invention is that the rim member inboard is scribbled glass powder with low melting point, with its be attached to glass plate around, by mould assembling, the high temperature heating makes the glass powder with low melting point fusion that glass plate and rim member are sintered into one.
In sum, the present invention has following technique effect:
1, because sealing surface is not the plane, but utilize the side of sheet glass to make sealing surface, make the vacuum glass effective area increase, thereby enlarged vacuum chamber volume, can prolong the application life of vacuum glass, also can in vacuum chamber, lay miscellaneous parts such as getter, heater easily, having expanded vacuum glass should increase by empty glass effective area, thereby enlarged vacuum chamber volume, can prolong the application life of vacuum glass, also can in vacuum chamber, lay miscellaneous parts such as getter, heater easily, expand the vacuum glass application.
2,, therefore higher with the vacuum glass intensity of metal frame sealing-in because the mechanical strength of metal is higher.
3, owing to be to paste metal frame, make that the glass powder with low melting point sealing surface is not the plane, a right angle is arranged, reduced the gas leakage probability, can improve the yield rate and the life-span of vacuum glass at the sheet glass periphery.
4, owing to adopt the metal frame sealing-in, can adorn outside framework in addition, save cost.
