Description

Equipped with protective frame, rolling support metal brazing interlayer control vacuum insulation glass plate Technical field

The invention relates to using vacuum brazing technology to braze and seal glass and metal to manufacture a functional glass plate. It belongs to the field of glass building materials.

Background technique

At present, the mainstream of functional glass is insulating glass and vacuum glass.

technical problem

Insulating glass insulation performance is not ideal, because there is no mutual support between the two layers of glass, can not rely on each other, making the glass weak resistance to wind pressure, easy to break due to glass resonance. At the same time, because there is no protective frame around the insulating glass, it is easy to break the insulating glass due to bumping the glass corners during transportation and installation.

Vacuum glass is supported by sandwiching two layers of glass plates, and the periphery is sealed and sealed by sealing and adhesive bonding. Vacuum glass is currently the best transparent energy-saving functional glass, with a series of advantages such as light weight, thin thickness, small heat transfer coefficient, good sound insulation effect, etc. It is an ideal energy-saving building material. However, because of its expensive production cost and the inability to meet the safety requirements of toughened glass required by high-rise buildings, it has not yet been applied on a large scale. Because the sealing adhesive around the vacuum glass is bonded to a low-temperature glass fusion seal, its manufacturing process, cost, yield, mechanical properties and size specifications are greatly restricted, and it is difficult to achieve the tempering treatment of the glass plate. The glass strength and safety performance are affected. Once the glass frit edge is damaged due to stress and other reasons, the entire vacuum glass will lose good sound insulation and thermal insulation performance.

Technical solution

Equipped with protective frame rolling support metal brazing interlayer control vacuum insulation glass plate, including flat glass, gap isolation support, aluminum or aluminum alloy brazing frame, stainless steel frame.

The two flat glasses of equal size and corresponding to each other are separated and supported by the distribution of a series of convex points separated by the pressing roller, and the embossed glass plate supported by the frame gap isolation support, and then the frame gap of the two embossed glass plates is isolated Support the complementary cover and the hinged piece to make a hollow isolation gap between the two flat glasses. The flat glass frame gap is isolated on the joint of the supporting and sealing surface, and is covered with a closed-loop aluminum or aluminum alloy brazing frame with at least one joint inlaid in a “mountain” shape. The two glass plates constituting the spaced interlayer cavity correspond to each other in outline shape and size. The edges of the two glass plates are provided with a ring-shaped closed glass plate rolling gap with the same height as the raised point to isolate the supporting frame. A

The embossing of the glass sheet is carried out in the production stage of the original glass sheet, or in the tempering stage of the glass sheet.

In the interlayer cavity between two glass plates, there is a long-acting getter.

The outer side of the closed-loop aluminum or aluminum alloy frame with a "mountain" shape is wrapped with a "U"-shaped closed-loop corrugated stainless steel frame with the cross-section of the inverted "U"-shaped closed-loop corrugated stainless steel frame, and the hollow laminated glass The outer periphery of the panel is stretched and set, and the self-rebound of the closed-loop corrugated stainless steel frame is used to make the cross section be an inverted "U"-shaped closed-loop corrugated stainless steel frame, and the "mountain"-shaped closed loop outside the periphery of the hollow laminated glass panel The outer sides of the aluminum or aluminum alloy frame are tightly fitted together. The two glass edges are made of hollow laminated glass blanks inlaid with a "mountain" cross-section, which is connected with a closed-loop aluminum or aluminum alloy frame and a stainless-steel closed-loop protective frame.

Or the outer side of the "mountain"-shaped closed-loop aluminum or aluminum alloy frame on the outer periphery of the hollow laminated glass plate, wrapped with a closed-loop stainless steel frame with a cross-section of "L" and an anti-"L" shape, and a cross-section of "mountain" The outside of the "closed-loop aluminum or aluminum alloy frame" closely fits together. The two glass edges are made of hollow laminated glass blanks inlaid with a "mountain" cross-section, which is connected with a closed-loop aluminum or aluminum alloy frame and a stainless-steel closed-loop protective frame.

After that, at least one glass blank is sent into the vacuum furnace, heated and evacuated, and electrothermal brazed to achieve vacuum brazing of the stainless steel frame, aluminum or aluminum alloy and glass, and unsealing the long-acting getter. After the vacuum furnace is ventilated and cooled, the furnace is opened, and a vacuum insulation glass plate with a protective frame rolling support metal brazing interlayer control is prepared.

Aluminum or aluminum alloy brazing materials include Al and brazing materials containing Al include AI-Si system, Al-Cu-Si system, and Zn-AI system.

A method for manufacturing vacuum thermal insulation glass plate with protective frame rolling support metal brazing interlayer control, including glass plate, aluminum or aluminum alloy brazing profile, stainless steel frame, vacuum brazing furnace. Between the two glass plates, a hollow interlayer is separated by a supporting frame. The two glass plate sealing covers and the surface and the edge of the glass plate are provided with aluminum or aluminum alloy brazed profiles. The aluminum alloy brazed profile frames are wrapped with stainless steel frames , Made into hollow laminated glass blank.

After that, place at least one blank laminated glass blank into a vacuum furnace equipped with a support base, fixed support fixture or tray, and wrap it outside the junction of the closed-loop aluminum or aluminum alloy frame with a "mountain" shape. A stainless steel frame is connected with a compact electric clip, and another compact electric clip is connected to another point of the stainless steel frame at an equal distance to form a two-way conductive loop with equal resistance wrapped around the glass frame. Close the vacuum furnace door and heat and vacuum the hollow laminated glass sheet blank in the vacuum furnace. When the set heating temperature, vacuum degree and set evacuation time below the tempered glass tempering temperature of 388℃ are reached, low-voltage, high-current heating power is connected to the two compact electric clips on the hollow laminated glass blank .

Since the resistance of the aluminum or aluminum alloy frame among the three of the stainless steel frame, glass, aluminum or aluminum alloy frame is the smallest, the current in the aluminum or aluminum alloy frame is the largest, the aluminum or aluminum alloy frame quickly heats up, and itself quickly heats up and melts evenly. Under the capillary action of the contact gap between stainless steel and glass, glass and glass, stainless steel and stainless steel, and the cohesion of the solder after melting, the molten solder and glass brazing surface and stainless steel brazing surface are fully immersed and wetted to achieve Brazing of glass surface and stainless steel surface by aluminum or aluminum alloy. At the same time, the long-acting getter close to the edges of the two glass plates in the interlayer cavity between the two glass plates is unsealed.

In this process, aluminum quickly heats up and turns into liquid aluminum, and the glass brazed with stainless steel and aluminum is not completely softened due to its poor thermal conductivity and short heating time. At 720°C, the main component of glass, Si02, and Al produce a chemical reaction: 4A1+3Si02=2A1203+3Si, that is, the interface between glass and aluminum can be firmly bonded due to a chemical reaction. At the same time, at 720°C, the stainless steel is not softened, and the surface of the oxide layer of the stainless steel reacts with aluminum, that is, the interface between the stainless steel and aluminum is also firmly bonded due to the chemical reaction. However, after all, the temperature of 720°C is already the softening temperature of ordinary glass. Therefore, if the brazing temperature is lowered, it not only ensures that the glass is not significantly softened, but also meets the process requirements. Aluminum alloy brazing material is used to reduce the brazing temperature between the glass and stainless steel frame, improve the brazing quality between glass and stainless steel, and reduce the difficulty of the brazing process.

Although aluminum or aluminum alloy brazing material has good cutting properties, considering that the linear expansion coefficients of glass and aluminum or aluminum alloy brazing material differ greatly, in the cooling process, due to inconsistent shrinkage, it will be on the brazed surface A certain amount of stress is generated. Therefore, the stainless steel frame is deformed as much as possible to absorb the stress caused by the thermal expansion and contraction of the aluminum or aluminum alloy brazing material to ensure the brazing quality between the stainless steel frame and the glass.

At the same time, due to the deeper design of the U-shaped closed-loop stainless steel frame groove, the corresponding closed-loop aluminum or aluminum alloy frame is also longer, so the brazed connection sealing layer formed is thicker, making the aluminum or aluminum alloy and glass It has high brazing strength with stainless steel and good airtight sealing performance.

After the aluminum or aluminum alloy frame is heated and evenly melted, the resistance will suddenly increase and the current will instantly decrease. Therefore, this phenomenon can be used to automatically and intelligently control the energized heating time, accurately control the brazing temperature, and achieve good vacuum brazing of aluminum or aluminum alloys with flat glass and stainless steel frames.

When the brazing heating power is cut off in time, the brazing layer of aluminum or aluminum alloy cools down, and gradually forms a temperature field with glass and stainless steel frame, the temperature tends to be consistent, and achieves a good brazing connection. After that, directly spray water to the vacuum furnace. The water vaporizes and evaporates instantly under vacuum to generate air pressure. Under the action of air pressure, the stainless steel frame quickly compacts the softened aluminum or aluminum alloy brazing layer and makes it exothermic and solidifies, and achieves a rapid and substantial cooling of the vacuum furnace. Since stainless steel, aluminum or aluminum alloy are good thermal conductors, and the edge of the glass is wrapped with aluminum or aluminum alloy brazing material, it can make the glass in the stainless steel frame evenly radiate heat and cool down, so that the glass in the stainless steel frame can get After the tempering process, air is passed in, or the cooling device inside the vacuum furnace is turned on to cool the vacuum furnace.

Or when the brazing heating power is cut off in time, the aluminum or aluminum alloy brazing layer cools down, and gradually forms a temperature field with glass and stainless steel frames, the temperature tends to be consistent, and achieves a good brazing connection. After that, the vacuum furnace is ventilated with air The air absorbs heat and expands to generate pressure. Under the action of air pressure, the stainless steel frame quickly compacts the softened aluminum or aluminum alloy brazing layer and makes it exothermic and solidifies. After that, spray water to the vacuum furnace to make the water absorb air The heat reduces the temperature of the vacuum furnace, so that the glass in the stainless steel frame is moderately tempered, and then, or the cooling device provided in the vacuum furnace is turned on to cool the vacuum furnace.

Or when the brazing heating power is cut off in time, the aluminum or aluminum alloy brazing layer cools down, and gradually forms a temperature field with glass and stainless steel frames, the temperature tends to be consistent, and achieves a good brazing connection. After that, the vacuum furnace is ventilated with air , The air absorbs heat and expands to generate pressure, and the stainless steel frame quickly compacts the softened aluminum or aluminum alloy brazing layer under the action of air pressure and allows it to radiate and solidify. After that, the hot air is released and the cold air is filled. Cool the vacuum furnace, or turn on the cooling device in the vacuum furnace to cool the vacuum furnace. The aluminum or aluminum alloy brazing material in the stainless steel frame will naturally cool and solidify, causing the glass in the stainless steel frame to lose its tempering characteristics.

Through the above process, the quality of glass and stainless steel brazed by aluminum or aluminum alloy is improved, and the characteristics of the glass in the tempered glass stainless steel frame are changed, so that the flat glass within the inner edge of the closed-loop stainless steel frame is still tempered glass, or the closed-loop stainless steel frame groove The wrapped glass is moderately tempered, or the glass wrapped in the closed-loop stainless steel frame groove loses the tempering characteristics and has a glass plate with vacuum interlayer.
