Problems solved by technology

[0004] However, the method of sealing the air suction port in the above-mentioned prior art has the following defects: 1) The heating temperature is high, which easily destroys the tempering properties of the tempered glass as the upper / lower flat glass panel 6, and the glass solder 10 is a brittle material after fusing , its mechanical strength becomes worse; 2) The ductile material (such as corrosion-resistant stainless steel or alloy material) constituting the sealing sheet 11 is directly combined with the brittle material formed by the glass solder 10, and there is a large difference in the coefficient of thermal expansion between the two, making the finished product When the vacuum glass is used in harsh environments with drastic temperature changes, it will cause rupture tension in the joint surface of the two, forming molecular-level cracks, which will reduce the vacuum performance of the vacuum glass or even completely disappear.

Embodiment Construction

[0018] Embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0019] figure 1 It is a schematic diagram of a vacuum glass sealing sheet according to a preferred embodiment of the present invention, the sealing sheet covers the air suction port 9 on the glass panel 6 and aligns with its center. A solder 3 is arranged between the glass panel 6 and the sealing substrate 1 . In order to realize the sealing of the air extraction port 9 in a low-temperature environment, the solder 3 is a low-melting-point solder capable of melting between 150°C and 350°C.

[0020] exist figure 1 Among them, since the thermal expansion coefficient of the solder 3 after solidification is quite different from that of the glass, in order to ensure the welding strength and sealing performance, the solder 3 is required to have good mechanical properties, its elongation ≥ 20%, and the tensile strength ≥20MPa.

[0021] like figure 1 As...

Abstract

A vacuum glass sealing structure and a method for forming the vacuum glass sealing structure. The vacuum glass sealing structure includes an air-exhausting port (9) which is formed on a glass surface plate (6), a sealing substrate (1) which covers the air-exhausting port (9) and is aligned with the center of the air-exhausting port (9), and a solder (3) which is arranged between the glass surface plate (6) and the sealing substrate (1). The structure is characterized in that the solder (3) is a low-melting-point solder which can melt at 150-350 DEG C.

Description

technical field [0001] The invention relates to a vacuum glass sealing structure and a method for forming the vacuum glass sealing structure, in particular to a structure for sealing an air suction port of a vacuum glass by using a sealing sheet and a preferred fusing material, which is suitable for flat or curved vacuum glass. Background technique [0002] As an excellent building material, the excellent performance of vacuum glass in terms of heat insulation and sound insulation has been increasingly recognized and adopted by the industry. In order to maintain long-term heat insulation and sound insulation effects, in addition to using the built-in encapsulated getter to maintain the vacuum degree of the vacuum layer, it is more important to maintain the sealing of the edges and the firm and reliable sealing of the suction port. [0003] Figure 4 A schematic diagram of the vacuum glass sealing method in the prior art is shown. Figure 4 The shown vacuum glass includes upp...
