The attention of energy-saving field；Vacuum flat glass or hollow plate glass are a kind of heat-insulated, sound insulation rate height, the high high-tech of light transmission
Skill product, production technology are related to the sciemtifec and technical spheres such as vacuum technique, welding technique, automatic technology.Vacuum flat glass can be wide
It is general to be applied to building, application of solar energy, freezer box and freezer box transport and agricultural greenhouse greenhouse etc..
The vacuum glass of merchandized handling is generally reheated using installation exhaust pipe after first high temperature edge sealing, cooling and is taken out at present
Vacuum, the two-step method finally sealed, batch production technique, not only production capacity is low, and it is at high cost, qualification rate is low.It is additionally useful for
The substrate of production vacuum glass generally uses tempered glass, the manufacturing method of vacuum tempered glass be on one piece of tempered glass with
Certain intervals place support column, and suitable film layer are plated on tempered glass, but coating and glass bond strength be not high, so
Solder containing pb is smeared at glass surrounding edge sealing afterwards, then another piece of tempered glass is pressed on solder and support column, its is whole
Body is put into vacuum drying oven or on heating platform, is heated to 450 DEG C or more conjunction welderings or sintering, is completed the system of vacuum or hollow glass
It is standby.If soldering object changes simple glass into, because heating temperature is higher than 450 DEG C, simple glass is caused to become semi-tempered glass, institute
It cannot achieve with the prior art and vacuum glass prepared using simple glass.
Summary of the invention
The invention aims to solve the problems, such as that the prior art cannot achieve to prepare vacuum glass using simple glass, and
A kind of method for being prepared using simple glass and having negative-pressure vacuum glass in cavity is provided.
A method of it is prepared in cavity using simple glass with negative-pressure vacuum glass, is specifically realized by the following steps
:
One, frosting treatment: carrying out frosting treatment to the position to be welded of simple glass using physical method or chemical method,
Obtain simple glass after frosting treatment；
Two, aluminium foil or alloy foil metalized: are cut into the position to be welded with simple glass after frosting treatment
Equivalent width it is band-like, aluminium foil with a thickness of 0.05mm~1mm, alloy foil with a thickness of 0.05mm~1mm, then carry out clear
It washes, obtains aluminium strip；Aluminium strip is laid in after frosting treatment on the position to be welded of simple glass, with laser aid, microbeam etc. from
Sub-device or high-energy beam device are cooled to room temperature, i.e., until aluminium strip is completely melt once in aluminium strip surface progress Surface scan
The metalized of the position to be welded of simple glass, obtains simple glass after metalized after completion frosting treatment；
Three, it assembles: 1., will place solder foil at the position to be welded of simple glass after two pieces of metalizeds, wherein
One piece is used as lower glass plate, and another piece is used as upper glass plates, and the solder foil is the solder that fusing point is lower than 450 DEG C；2., will sealing
The upper and lower surfaces of frame carry out metalized, obtain sealing frame after upper and lower surface metalized；3., corresponding lower glass
The welding position of plate places sealing frame after upper and lower surface metalized in lower glass plate, after upper and lower surface metalized
It seals array in frame region and places support column, the welding position for then corresponding to upper glass plates covers upper glass plates in upper and lower surface gold
After categoryization processing in sealing frame, simple glass after being assembled；
Four, vacuum brazing: simple glass after assembling being put into vacuum brazing furnace and carries out vacuum brazing, vacuum degree 1.0
×10-2Pa~5.0 × 10-4Pa, brazing temperature are lower than 460 DEG C, and brazing temperature >=solder foil fusing point, holding time of brazing
