Description
Affiliated technical field
The present invention relates to a kind of silk screen printing and prepare the method for isolating the point of suppon array between the vacuum glass substrate.Vacuum glass is meant between two or the multi-disc glass spaced staggered relatively, and a plurality of small isolation point of suppon are set between sheet glass and sheet glass form lattice arrays, through behind the exhaust sealing, form the vacuum tight cavity between sheet glass and the sheet, obtain a kind of heat insulation, transparent plate material that sound-proofing properties is excellent.Be used for buildings and a plurality of technical fields such as transportation means door and window, cooling apparatus viewing window.The present invention relates generally to and isolates the novel method that supports the dot matrix making between the vacuum glass substrate a kind of the preparation.
Background technology
At present, it is similar substantially to relate to the structure of vacuum glass in the technique known.Fig. 1 is typical vacuum glass structure, and A is a prebasal plate glass among Fig. 1; B is a metacoxa glass; A is the isolation point of suppon between the forward and backward glass substrate; B represents the sealing layer of sealing-in prebasal plate glass A and metacoxa glass B; F is a venting hole.The cavity gap that forms between two sheet glass is a vacuum.
Exist in the known vacuum glass manufacturing technology and isolate point of suppon manufacture craft defective:
Between two or multi-disc glass, metal or high molecular isolation point of suppon a are set in the technique known, generally need place a diameter 0.5mm, the isolation point of suppon of the cylinder shape of high 0.2mm or other shape every 20-40mm.Glass substrate and glass-based edges of boards portion make the gap between glass substrate and the glass substrate be in vacuum state with low melting glass or organic adhesive sealing through sealing after the exhaust, make vacuum glass.
The vacuum glass that seals with low melting glass between glass substrate and the glass substrate, general with the isolation point of suppon of metal cylinder as vacuum glass, because glass surface unfairness and the not parallel and unfairness of isolation point of suppon metal cylinder upper and lower surface, the right cylinder that usually causes isolating support tilts, thereby make isolating points dislocation or with sheet glass between just some contact or the line contact, rather than contact by the face that design needs.The right cylinder dislocation of isolate supporting, some contact or line contact all will cause vacuum glass stress concentration and mechanical strength and work-ing life of directly breaking or reducing vacuum glass in manufacturing processed.In addition, the isolation point of suppon is opaque, influences the attractive in appearance of product; Isolating point of suppon is metal, and thermal conductivity is big, if can will isolate point of suppon material inorganic materials, then the thermal conductivity of vacuum glass product will reduce greatly.
With the isolation upholder of macromolecular material as vacuum glass, because the upper limit temperature of heat tolerance of general macromolecular material is lower than 250 ℃, therefore, the sealing material of make isolating the sealing-in limit portion that the vacuum glass of upholder uses with macromolecular material generally can only be an organic adhesive.The vacuum glass of Zhi Zaoing in use produces tiny crack owing to organic adhesive is easy to reasons such as embrittlement or organic adhesive inherent aging blemiss in cold winter in this way, causes leaking gas and the effect of loss of vacuum glass.
In addition, no matter be the isolation upholder of metal or macromolecular material because it is not only thin but also many to isolate upholder, pile up time-consuming, fixing difficult, complex manufacturing technology.
Summary of the invention
Propose a kind of silk screen printing and prepare before and after the vacuum glass and isolate the method that supports dot matrix between the glass substrate in order to overcome aforementioned not enough the present invention that existing metal and macromolecular material isolate point of suppon as vacuum glass.
The vacuum glass faceplate making method that the present invention proposes comprises following key step:
1. with size cutting, edging, the cleaning on request of glass raw sheet.
2. making diameter with mechanical drill or laser-beam drilling machine on a glass sheets is the venting hole of 1-5mm, and this sheet glass is called prebasal plate glass, and correspondingly, another sheet glass is called metacoxa glass.
3. isolate the point of suppon array on glass making of metacoxa of method for printing screen.The non-crystalline type low-melting-point glass powder (afterwards being called low-melting-point glass powder M) and the organic solution that are slightly less than the thermal expansivity of face glass with thermal expansivity are mixed with the slurry that a kind of rheological is suitable for silk screen printing.Use method for printing screen then about metacoxa printing diameter on glass 0.5-1.5mm, the cylindric wet film lattice array of the about 30-250 μ of thickness m, each idea spacing distance in length and breadth are 20-100mm.Through on the glass substrate of back, forming the array that isolation point of suppon a as shown in Figure 2 forms behind super-dry, the sintering.The diameter of this sintered compact is 0.1-1.0mm, and thickness is 20-250 μ m, the sealing-in floor height 1-20 μ m that uses than vacuum glass faceplate sealing-in limit portion.
4. will be used for front glass substrate and the back glass substrate another kind of non-crystalline type low-melting-point glass powder (afterwards being called low-melting-point glass powder N) of sealing be mixed with can silk screen printing slurry, regulate the viscosity and the rheological of slurry, on the front glass substrate limit with method for printing screen around print the wide about 5mm of one deck, the banded wet film of the thick glass powder with low melting point slurry of thick about 30-300 μ m.Through on sheet glass, forming b as shown in Figure 3 after the drying and sintering, be used for the low melting glass rete of seal glass edges of boards portion, abbreviate sealing layer as.
Front glass substrate and back glass substrate is superimposed face-to-face 5., the face of isolating point of suppon is promptly arranged and have the face of sealing layer staggered relatively.Getter is put near venting hole corner.Periphery with heat-resisting elastic mechanical clamp clamps face glass, anchor clamps will guarantee that the face glass periphery is stressed evenly, and be subjected to thermal softening isolating point of suppon and sealing layer, can continue maintenance during forward and backward glass substrate pitch smaller and give forward and backward glass substrate uniform pressure.Heat the sealing temperature that reaches the sealing layer of making of low-melting-point glass N through intermittent type electrical heater or grill-hearth travelling oven then, be generally 380-500 ℃, under this temperature, the isolation point of suppon of making of low-melting-point glass M sintering also can soften deformation under stressed effect, because the thickness of point of suppon is a little more than the thickness 1-20 μ m of limit portion sealing layer, under the chucking pressure effect, point of suppon sintered compact deformation quantity under synthermal is a little less than the deformation quantity of limit portion sealing layer sintered compact, guaranteed like this to realize under the prerequisite of hermetic seal in limit portion, each point of suppon all can contact with front-back baseboard in the point of suppon array, stressed evenly, overcome the defective of each point unbalance stress in existing metal support height is inconsistent and front and back glass baseplate surface unfairness brings stress concentration and the point of suppon array.The sealing temperature of the sealing layer of making at low-melting-point glass powder N kept 1-15 minute, evenly reduced to room temperature then.Finish the making and the hermetic seal of limit portion of vacuum glass point of suppon.
One of step 3,4, key problem in technology of 5 are to make the low-melting-point glass powder M that isolates upholder and the difference of low-melting-point glass powder N material property.Low-melting-point glass powder M has similar thermomechanical property with low-melting-point glass powder N, here said thermomechanical property is meant: the sample behind the sintering is being subjected at the uniform velocity heating under the constant external force, behind the softening temperature of temperature greater than glass of sample, measure the deformation quantity in the heat-processed, be called hot mechanical paths with the deformation quantity curve that mapping obtains to temperature.Low-melting-point glass powder M and low-melting-point glass powder N have the hot mechanical paths of appearance similar separately at it more than the softening temperature, but two samples reach the temperature difference of identical deformation quantity, and low-melting-point glass powder M is higher more 3-30 ℃ than the temperature that low-melting-point glass powder N reaches identical deformation quantity.In addition, low-melting-point glass powder M is different with the glass softening point of low-melting-point glass powder N, and the softening temperature of low-melting-point glass powder M is higher approximately 3-30 ℃ than the softening temperature of low-melting-point glass powder N.Say with popular words, make the low-melting-point glass powder M that isolates point of suppon exactly and under sealing temperature, omit more firmly than the low-melting-point glass powder N that is used for sealing-in limit portion.Like this, guaranteeing that vacuum glass faceplate limit portion reaches under the prerequisite of hermetic seal, guaranteeing that each isolation point of suppon all has excellent contact with front glass substrate and back glass substrate, makes each isolation point of suppon stressed evenly.
Two of step 3,4,5 key problem in technology is the accurate couplings of making the height of the height of isolating upholder and sealing layer.By control silk screen printing parameter, the thickness of the sealing layer b in the control chart 3 behind the sintering is than the low 1-20 μ m of thickness of the isolation point of suppon a among Fig. 4.Like this, during forward and backward glass-based edges of boards portion sealing by fusing, under the pressure effect of anchor clamps, heat, make each isolate point of suppon when being subjected to thermal softening can both with two sheet glass excellent contact, isolate point of suppon like this and can play the good supporting effect, improve the yield rate and the mechanical strength of vacuum glass goods.
In addition, the gap between the known vacuum glass is about 0.2mm, and the present invention is owing to have only 20-250 μ m with the isolation support thickness of method for printing screen making and the sealing layer thickness of edge sealing.Reduced the gap between sheet glass and the sheet glass.
After the forward and backward glass substrate sealing-in of vacuum glass, the isolation point of suppon shape of formation as shown in Figure 4.By aforesaid method, making each isolate point of suppon all has excellent contact with forward and backward glass substrate, has improved the intensity and the good article rate of vacuum glass.
6. vacuumize and seal venting port.
The panel that the hermetic seal of limit portion is connected vacuumizes, make vacuum tightness reach about 0.0001Pa after, the sealing venting port.
7. make vacuum tightness in the air-breathing further raising vacuum glass faceplate of the getter that is placed on panel venting hole edge with ratio-frequency heating.
8. detect the performance of vacuum glass, install plastics or plastic-steel frame after meeting the requirements additional, obtain qualified vacuum glass faceplate goods.
The invention has the beneficial effects as follows, isolating aspect the point of suppon making, compare with known vacuum glass manufacturing technology and have the following advantages: (1) adopts method for printing screen to make, and improves the make efficiency of isolating point of suppon and has reduced production cost; (2) can play the good supporting effect owing to isolate point of suppon, improve the yield rate and the mechanical strength of vacuum glass goods; (3) reduce gap between sheet glass and the sheet, follow-up vacuumizing and exhausting activity time is shortened, enhanced productivity, reduced the thickness of vacuum glass faceplate simultaneously.(4) metal isolation point of suppon is opaque, and the isolation point of suppon that the present invention makes is translucent sintered compact, has improved the aesthetics of vacuum glass.(5) thermal conductivity of metallic support point is much larger than the thermal conductivity of inorganic materials, and the heat conduction of the inorganic low-melting-point glass sintered compact point of suppon that the present invention makes itself is far below the thermal conductivity of original technology, thereby can reduce the thermal conductivity of vacuum glass product.(6) material cost of metallic support point itself is far above the material cost of low-melting-point glass used herein, and the present invention can reduce the comprehensive cost of vacuum glass.
