Abstract
The invention discloses a method for sealing metal and glass. The method comprises the following steps: firstly performing pre-oxidizing treatment, namely heating a sintering furnace to reach 700 DEG C, placing the metal into the sintering furnace after the heating, oxidizing and maintaining the temperature for 10 minutes to obtain an oxidization film, and then discharging the metal; adjusting the temperature of an inlet area in the sintering furnace to reach 870 DEG C; adjusting the temperature of a heating area to reach 920 DEG C; adjusting the temperature of a cooling area to reach 870 DEG C; charging nitrogen into an adjusting furnace after the temperature is adjusted to reach a stable state; assembling the metal with the oxidation film and the glass to form a loading plate; placing the loading plate into the sintering furnace after charging the nitrogen for 15 minutes; sequentially sintering through the inlet area, the heating area and the cooling area; mutually dipping the metal and the glass after sintering; sealing; and cooling after the sealing, wherein the glass and the metal are integrally contracted during gradually cooling.
Description
Technical field
The present invention relates to the method for the sealing-in of a kind of metal and glass.
Background technology
Just adopt assembly glue when metal current and glass carry out sealing-in, the tension of the mode of this sealing-in and twisting strength are not high, and assembly glue is industrial chemicals, easily discharge objectionable constituent, and human body is had to injury, affect environment.
Summary of the invention
The invention provides the method for the sealing-in of a kind of metal and glass, it not only tension and twisting strength high, and avoid discharging objectionable constituent, there are good insulating property simultaneously.
The present invention has adopted following technical scheme: the method for the sealing-in of a kind of metal and glass, it comprises the following steps: step 1, pre-oxidation treatment: sintering oven is warming up to 700 ℃, after intensification finishes, metal is put into to sintering oven and carried out producing oxide film after oxidation insulation 10min, then metal is taken out; Step 2, the temperature of regulating entrance region in sintering oven is 870 ℃, the temperature of heating zone is 920 ℃, the temperature of cooling area is 870 ℃, pass into nitrogen again in regulating stove after temperature regulation is stable, will be with metal and the rear support plate that forms of glass assembling of oxide film, carry out sintering through entrance region, heating zone and cooling area successively after putting into support plate in sintering oven after passing into nitrogen 15 min, after sintering, metal and glass carry out sealing-in after mutually infiltrating, carry out coolingly after sealing-in finishes, in cooling gradually process, make glass together with metal contracts.
When the present invention approaches when the coefficient of expansion of the coefficient of expansion of metal and glass, adopt matched seal between metal and glass, after metal and glass sealing sealing-in, in cooling gradually process, make glass and metal contracts be consistent, thereby reduce the internal stress produced due to glass and metal contracts.
When the present invention is greater than the coefficient of expansion of glass when the coefficient of expansion of metal, it between metal and glass, is the compression sealing-in, shrink greatly due to the contraction ratio glass of metal after metal and glass sealing, utilize glass to bear anti-pressure ability and make metal pair glass produce the purpose that stress has reached the compression sealing-in much larger than the characteristic of resistance to tension.The described support plate nearest apart from the sintering oven import and the fire door distance of sintering oven are 82mm, put into the process of support plate for every 6 min, one support plate is put into to sintering oven, start often from fire door, to push a support plate just from a support plate sintered of stove tail taking-up from putting into the 20th support plate.Described metal is the 10# steel, and described oxide film is Z 250.The import tolerance of described nitrogen is 10-15L/min, and the outlet tolerance of nitrogen is 10-15L/min.
The present invention has following beneficial effect: after having adopted above technical scheme, the present invention carries out preoxidation to metal before sealing-in makes it to generate oxide film, oxide film is Z 250, then infiltrate mutually and form the chemical combination key by this layer of oxide film and glass, the bonding force that the bonding force of this chemical combination key adheres to much larger than other materials, therefore the product of glass fish metal sealing has enough tensions and twisting strength, and glass is a kind of ceramic, there is higher softening point temperature, therefore can not discharge any objectionable constituent in the comparatively high temps environment, the present invention has good stopping property leakage rate in addition, the stopping property leakage rate reaches 10
-3pa.Cm
3/ s, have good insulating property.
Embodiment
Embodiment mono-, the invention provides the method for the sealing-in of a kind of metal and glass, it comprises the following steps: step 1, pre-oxidation treatment: sintering oven is warming up to 700 ℃, after intensification finishes, metal being put into to sintering oven carries out producing oxide film after oxidation insulation 10min, then metal is taken out, metal is the 10# steel, and described oxide film is Z 250, step 2, the temperature of regulating entrance region in sintering oven is 870 ℃, the temperature of heating zone is 920 ℃, the temperature of cooling area is 870 ℃, pass into nitrogen again in regulating stove after temperature regulation is stable, the import tolerance of nitrogen is 10-15L/min, the outlet tolerance of nitrogen is 10-15L/min, will be with metal and the rear support plate that forms of glass assembling of oxide film, pass through successively entrance region after putting into support plate in sintering oven after passing into nitrogen 15 min, heating zone and cooling area carry out sintering, after sintering, metal and glass carry out sealing-in after mutually infiltrating, when the coefficient of expansion of the coefficient of expansion of metal and glass approaches, adopt matched seal between metal and glass, after metal and glass sealing sealing-in, in cooling gradually process, make glass and metal contracts be consistent, thereby reduce the internal stress produced due to glass and metal contracts, when the coefficient of expansion of metal is greater than the coefficient of expansion of glass, it between metal and glass, is the compression sealing-in, contraction ratio glass due to metal after metal and glass sealing shrinks large, utilizing glass to bear anti-pressure ability makes metal pair glass produce the purpose that stress has reached the compression sealing-in much larger than the characteristic of resistance to tension, in the import of distance sintering oven, the fire door of nearest support plate and sintering oven distance is 82mm, put into the process of support plate for every 6 min, one support plate is put into to sintering oven, from putting into the 20th support plate, start often from fire door, to push a support plate just from a support plate sintered of stove tail taking-up.Carry out coolingly after sealing-in finishes, in cooling gradually process, make glass with metal contracts together with, then support plate after sealing-in is tested, put in storage.
When metal is other metallic substance, increase by 40 ℃ on the basis that in the sintering process of this metallic substance and glass, the temperature of each warm area is each warm area temperature of 10# steel sintering process in embodiment mono-, other techniques are identical with embodiment mono-.
