Technical Field
The invention belongs to the technical field of building material production, and particularly relates to a manufacturing method of toughened vacuum glass and the toughened vacuum glass manufactured by the manufacturing method.

There are: when the solder is melted at high temperature at the edges of two parallel toughened flat glass sheets, the performance of the toughened glass sheets can be seriously reduced, even the toughened performance is lost, particularly the peripheral strength of the toughened flat glass sheets can be greatly reduced, which is a main reason that the conventional vacuum glass sheets often crack from the periphery to cause fragmentation. If the vacuum glass with multiple vacuum layers is manufactured by the manufacturing method, the sealing edges of the vacuum layers are directly exposed outside, so that the potential safety hazard of air leakage of the sealing edges is greatly increased, and the weight and the cost are overhigh.
The thickness of the vacuum layer of the existing vacuum glass is 0.1mm-0.2mm, and the vacuum degree is as high as 1 multiplied by 10-1Pa——1×10-3Pa, the presence of: the vacuum chamber is too thin, even at a thickness of up to 1X 10-1Pa——1×10-3The vacuum degree of Pa can only achieve better heat preservation performance, and the vacuum degree of the vacuum cavity is extremely sensitive to the problem of material deflation. The higher the vacuum degree is, the greater the atmospheric pressure borne by the vacuum wall and the support column is, and the lower the safety of the product is. In order to withstand the large atmospheric pressure of the high vacuum on the vacuum walls and the support columns, the support between the two pieces of glass is usually stainless steel,and the support spacing is only 25 mm; the thermal conductivity of stainless steel is 17W/m.K, while the thermal conductivity of glass is 0.76W/m.K-1.1W/m.K, which are different by about 20 times; the low breaking strength and bending strength are another main reason causing high breakage rate in engineering application, and the low safety of the existing vacuum glass is a bottleneck seriously influencing the development of the vacuum glass industry.

Further, in the above-mentioned case,
(1) after the pins are placed at the corresponding positions of the inner surface of the face wall, the separation layer is placed on the upper surfaces of the pins, and the periphery of the separation layer is overlapped on the inner edges of the side wall sealing surfaces or is connected with the inner edges of the side wall sealing surfaces.
(2) And placing a second layer of pins at corresponding positions on the surface of the partition layer, so that the second layer of pins and the first layer of pins are vertically aligned.
(3) And placing the melted sealing low-temperature sealing material on the side wall sealing surface, so that the sealing low-temperature sealing material is connected with the periphery of the separation layer and completely wraps the gap between the peripheral table of the separation layer and the side wall sealing surface.
(4) And (3) downwards opening the other piece of toughened edge-folded glass, placing the side wall sealing surface on the melted sealing low-temperature sealing material to realize sealing, and tightly connecting the inner surface of the surface wall with the upper surface of the pin, thus finishing the assembly of the toughened vacuum glass with double vacuum layers.
Further, in the above-mentioned case,
(1) after the studs are placed at the corresponding positions on the inner surfaces of the face walls, the separation layer is placed on the upper surfaces of the studs, and the periphery of the separation layer is connected with the inner surfaces of the side walls.

Further, before the sealing material with low temperature is placed, the sealing surface of the side wall is preheated, and the preheating temperature is 280-300 ℃.
Further, before the sealing low-temperature sealing material is placed, the preheated side wall sealing surface is locally and temporarily heated to 320-450 ℃.
Furthermore, the separating layer is made of Low-E glass, coated glass or a metal sheet with the thickness of 0.03mm to 0.3 mm. And the side wall is formed with a folded edge to form a widened sealing surface.
Furthermore, in the assembling process, the upper surface or/and the lower surface of the pin is/are provided with melted low-temperature sealing material for the pin.

The purpose of the invention can be realized by the following technical scheme:

The workpiece is preheated at 250-300 ℃ and simultaneously vacuumized, after the set vacuum degree is reached, the sealing heating device is started to locally heat the sealing low-temperature sealing material, so that the sealing low-temperature sealing material is melted, and the side wall sealing surfaces are hermetically sealed into a whole. When the vacuum degree and the temperature in the vacuumizing sealing device are similar to or the same as the outside, the manufacturing of the toughened vacuum glass is finished.
The tempered vacuum glass is manufactured according to any one of the methods.
The invention has the advantages that:
1. in the process of forming the flanged glass, the flatness of the surface wall of the flat glass or the float glass is not influenced, and the intact transparent and imaging performance of the flanged glass is still maintained.
2. The preheating and heating in the manufacturing process do not influence the toughening performance of the product.
(1) Effect of side wall thickness 2mm-4mm on attenuating thermal influence: the heat conducting distance is prolonged during heating and sealing. Secondly, the sectional area of the heat bridge is reduced, thereby reducing the heat conduction quantity. And the thinner the thickness is, the shorter the time required for heating is, and the smaller the thermal influence on the periphery is.
(2) The low-temperature sealing material is placed on the sealing surface after being melted: even if the side wall sealing surface is preheated at 280-300 ℃ and locally heated at 350-450 ℃ to enhance the sealing strength, the side wall sealing surface is kept at the temperature of more than 300 ℃ for 1-3 minutes, and the side wall with the thickness of only 2-4 mm has effective attenuation effect on heat energy, so that the condition of influencing the glass toughening performance is not provided.
(3) Because the requirement on the sealing strength of the separation layer is low and the requirement on local heating is not met, the influence of the low-temperature sealing material of the molten separation layer is less.
3. The manufacturing method of the special multi-vacuum layer and high-thickness vacuum layer endows the product with excellent heat insulation performance and excellent safety and reliability. Therefore, the problem that the existing vacuum glass is low in safety, which seriously restricts the bottleneck and the stubborn disease of industry development, is solved, and is very important for the development of projects, products and industries.
The smaller the number of layers of the multi-layer heat insulation assembly, the greater the influence of the vacuum degree on the equivalent thermal conductivity coefficient of the multi-layer heat insulation assembly.
Because the vacuum glass is relatively vacuum, the thickness and the number of layers of the vacuum layer still have important effect on the heat preservation performance.
(1) The vacuum cavity is divided into a plurality of vacuum layers with the thickness of 1mm-12mm through the reflection separation layers, so that necessary and excellent precondition is created for greatly reducing the vacuum degree and obviously improving the heat preservation performance.
(2) The vacuum layer with the thickness of 1mm-12mm not only obviously improves the heat preservation performance, but also plays an important role in relatively maintaining the vacuum degree of the vacuum layer so as to ensure the continuous and long-term heat preservation performance. The optimal vacuum layer thickness is 6mm-12mm, even if the vacuum layer is measured by the thickness of 6mm, the volume of the vacuum layer is 50 times larger than that of the existing vacuum glass, namely, the influence of material outgassing on the vacuum degree can be reduced by 50 times, so that the functional degradation of the product in the service process is greatly inhibited, and the application of the product and the stubborn industrial development are severely restricted. The durability of the product is more than one hundred times of that of the prior vacuum glass under the combined action of the added multiple vacuum layers.
(3) The preferable vacuum degree is 20Pa to 2Pa, even if the vacuum degree is 2Pa, 1X 10 compared with the prior vacuum glass- 2The high vacuum degree of Pa is one hundred times lower, so that the atmospheric pressure born by a vacuum wall and a pin is greatly reduced;
(4) the vacuum degree in medium and low magnitude creates extremely favorable conditions for selecting the glass made of heat-degrading material as the pin, increasing the height of the pin and increasing the distance between the pins.
(5) The side wall integrated with the glass surface can multiply increase the bending strength of the product, and particularly has an important effect on enhancing the peripheral strength of the product which is most easy to crack.
4. The product has wide application market.
(1) The heat preservation performance is set correspondingly through the adjustment of the thickness, the number of layers and the vacuum degree of the vacuum layer, and the energy-saving requirements of 75% of building energy conservation, passive buildings and buildings with zero energy consumption on building doors and windows, curtain walls, walls and roofs are completely met.
(2) When the separation layer is made of glass, the product has high transparency and good imaging performance and is mainly used for building doors and windows, curtain walls and domes; when the separation layer is an aluminum sheet or a stainless steel sheet, the product is opaque, and the method is mainly used for heat preservation and decoration of opaque building curtain walls, walls and roofs.
