Description
Technical Field
The invention relates to a functional vacuum toughened glass plate manufactured by bonding and sealing glass and metal by utilizing a vacuum bonding technology. Belonging to the field of glass building materials.
Background
Currently, the main stream of functional glass is hollow glass and vacuum glass.
The insulating performance of the hollow glass is not ideal, and two layers of glass are not mutually supported and can not mutually borrow force, so that the glass has weak wind pressure resistance and is easy to break due to glass resonance. In addition, there is a problem that condensation occurs in glass after the adhesive leaks.
The vacuum glass is made up by using two layers of glass plates as sandwich layer, and making them pass through the processes of sealing adhesive, bonding, vacuumizing and sealing. The vacuum glass is transparent vacuum glass with the best energy-saving effect at present, has a series of advantages of light weight, thin thickness, small heat transfer coefficient, good sound insulation effect and the like, and is an ideal energy-saving building material. However, the high-rise building has not been applied on a large scale at present because of the expensive production cost and the fact that the safety requirements of the toughened glass required by the high-rise building cannot be met. Because the sealing adhesive on the periphery of the vacuum glass is bonded into low-temperature glass fusion seal, the manufacturing process, cost, yield, mechanical performance and dimension specification of the vacuum glass are greatly limited, and the tempering treatment of the glass plate is difficult to realize, so that the strength and safety performance of the glass are influenced. Once the glass-melt edge seal damages vacuum leakage due to stress and the like, the whole vacuum glass loses good sound insulation and heat preservation performance.
The above-mentioned disadvantages of the existing vacuum glass are caused by the design structure and the production process thereof. The prior vacuum glass is characterized in that two glass raw sheets are separated by a tiny support point array, the periphery of the glass raw sheets is sealed by a low-melting-point glass material in a melting way, and the vacuum glass is sealed after being exhausted by a glass exhaust tube, so that a vacuum layer with the thickness of only 0.1-0.2mm and the air pressure lower than 0.1Pa is formed. The production of vacuum glass must therefore be accomplished in a number of steps including 1) drilling of the extraction openings, 2) placement of the supports, 3) spreading of the glass braze, 4) glass lamination, 5) high temperature edge sealing/extraction opening brazing, 6) high temperature extraction/sealing, and 7) getter deblocking.
Applicant [ Liu Weijie ] applies for a low-cost tempered vacuum glass and a manufacturing method thereof, application number CN200910188347.2
The application provides vacuum glass and a manufacturing method thereof, which replace the existing stainless steel support laying process with a micro-convex point support integrated with a glass raw sheet, seal edges by using a low-temperature metal tin brazing technology which does not cause annealing of the tempered glass raw sheet, and integrate the traditional vacuum layer air extraction process and the sealing process into an air extraction and sealing integrated process.
Compared with the existing vacuum glass and the manufacturing process thereof, the application completes vacuumizing and braze welding sealing once, and the safety reaches the use standard of high-rise buildings. However, due to the need of coating sintered gold water, low tin soldering temperature, low heating temperature of a vacuum soldering furnace, insufficient air release of glass and tin soldering materials, poor vacuumizing effect, low vacuum degree of a glass vacuum interlayer and the like, the heat preservation and sound insulation performance of the vacuum glass are unsatisfactory.
According to the technical scheme of application number CN200910234678.5 of Nanjing industrial university, the surface of the glass is subjected to electroless copper plating metal surface treatment on the basis of the original process. After the heating system is started, the workpiece is heated to 550 ℃ along with the furnace, the temperature is kept until the vacuum degree in the furnace is 4 multiplied by 10 < -2 > Pa, the temperature of each part of the workpiece is uniform, the brazing furnace is continuously heated to the brazing temperature, the heating is stopped after the brazing furnace is kept for 10-30 min, the workpiece is slowly cooled along with the furnace, and the discharging temperature of the vacuum glass is below 50 ℃.
The high-temperature edge sealing process is a main reason for the fact that the existing vacuum glass cannot reach the national safety standard of high-rise buildings. National standards require that high-rise building glass components must be manufactured using tempered glass. However, because the melting temperature of the existing high temperature edge sealing glass braze is over 550 ℃ and is much higher than the annealing temperature 388 ℃ of conventional tempered glass, even if tempered glass is used to make vacuum glass, it will be annealed into ordinary glass during the edge sealing process.
The other regulation vacuum glass is formed by arranging a support on the middle interlayer of two layers of glass plates, bonding and forming the periphery of the glass plates through a sealing adhesive, and carrying out intermittent or continuous vacuumizing through a vacuum pump to regulate and preserve heat on the vacuum of the glass interlayers. Is the applicant of the prior patent application, and the patent number of the laminated glass curtain wall for controlling the vacuum degree of the cavity is 2010103000382.
The prior application patent realizes vacuum insulation of the glass interlayer through intermittent or continuous vacuumizing of a vacuum pump. However, in practice, it has been found that it is difficult to achieve a high vacuum due to the unreasonable design and poor reliability of the device. Meanwhile, when the adhesive is a single-layer silicone structure sealant, the adhesive strength can be ensured, but the air tightness is poor, and when the adhesive is adhered by the single-layer air-tight sealant, the air tightness can be maintained, but the mechanical strength cannot be ensured, so that the strength of the glass adhesive structure, the air tightness and the weather resistance are difficult to be simultaneously achieved. In both of these bonding methods, there is a problem that a large amount of bubbles are present in the bonding layer. There is also a problem that the vacuum glass is broken due to the collision of glass corners in the transportation and installation process because the periphery of the vacuum glass is not provided with a protective frame.
Due to the problems, the vacuum interlayer which can be pumped by the vacuum pump is rough vacuum, and the problem of serious vacuum leakage exists. And when the vacuum interlayer thickness is smaller, the vacuum glass has poorer heat preservation performance. Therefore, it is required to improve the heat-insulating effect of the vacuum layer by increasing the thickness of the hollow interlayer. But doing so makes the vacuum pump very energy consuming.
Disclosure of Invention
The invention is under the background of the conventional process technology, through researching the basic theory and generating inspiration from practice, the quality of the welded surface of glass and metal is improved by utilizing the vacuum electric heating brazing process, and the performance of the tempered glass in the stainless steel protective frame is ensured to be unchanged.
