Problems solved by technology

[0004] The applicant of the present invention disclosed a series of vacuum glass without air extraction port and its manufacturing method in the patent of vacuum glass applied in March, 2012. At high temperature and vacuum, the air and moisture absorbed by the solder, the volatile substances in the solder, the gas dissolved in the solder during the production process, and the decomposition of some oxides in the solder will cause a large number of bubbles in the solder , which greatly weakens the performance of the solder, especially the airtightness, which greatly affects the feasibility of this method
The existing mass-produced vacuum glass is all vacuum glass with an air extraction port, but there are complex manufacturing processes, low air extraction temperature (incomplete air extraction), single-piece vacuuming, high cost, low production capacity, and inability to make toughened vacuum glass. Cons of glass etc.

Embodiment 1

[0057] Embodiment 1: see figure 1 , the vacuum glass is composed of upper glass 1 and lower glass 2, the periphery of the two pieces of glass is welded together by low-temperature glass solder 4, and the middle is a vacuum layer. The production method is as follows: First, cut two pieces of flat glass of the required size according to the shape and size of the vacuum glass to be produced, drill a through hole at the corner of the upper glass 1 to form a suction port 3, and grind and chamfer the upper and lower glass And clean, dry, utilize mechanical spraying technology to prepare sealing strip 5 and 6 at the peripheral welding place of upper and lower glass and the periphery of air inlet 3 and corresponding place, and prepare support 8 on upper and lower glass with dispenser; Put the glass into the mold, put it in the hot bending furnace, heat up to the temperature of glass softening 550-750 ℃, rely on the gravity of the glass itself to make the glass downward to form a conve...

Embodiment 2

[0058] Example 2: see figure 2 The vacuum glass consists of upper glass 1 and lower glass 2. The two pieces of glass are tempered glass or half-tempered glass, one of which is low-emissivity glass. The production method is as follows: First, cut the required size according to the shape and size of the vacuum glass to be produced. A piece of flat glass and a piece of low-emissivity glass, i.e. Low-E glass, remove the film at the welding part of the low-emissivity glass, drill a through hole at the corner of the upper glass 1 as the air outlet 3, and grind the upper and lower glass edges and pour Corner and cleaning, drying, using screen printing technology to print sealing strips on the peripheral welding of the upper and lower glass and the periphery and corresponding positions of the air outlet 3; secondly, put the two pieces of glass into two forming molds respectively, and the forming mold has The upper mold and the lower mold (that is, the male mold and the female mold), ...

Embodiment 3

[0059] Embodiment 3: see image 3 The vacuum glass consists of upper glass 1 and lower glass 2. The two pieces of glass are tempered glass or half-tempered glass, one of which is low-emissivity glass. The production method is as follows: First, cut the required size according to the shape and size of the vacuum glass to be produced. A piece of flat glass and a piece of low-emissivity glass, remove the film at the welding part of the low-emissivity glass, drill a through hole at the corner of the upper glass 1 as the air outlet 3, and perform edge grinding, chamfering, cleaning and drying on the upper and lower glass , use screen printing technology to print sealing strips on the peripheral welding of the upper and lower glasses and the periphery and corresponding positions of the air outlet 3, and at the same time print the support 8 on one of the glasses; secondly, send the two glasses into the tempering furnace for Air-cooling and tempering to obtain tempered or semi-tempere...

Abstract

The invention discloses vacuum glass with edges and extraction opening both sealed with sealing strips. The vacuum glass comprises upper glass and lower glass which are convex glass or plain glass, wherein an extraction opening is formed in the upper glass; at least one sealing strip I is arranged at the periphery of the upper glass as well as that of the extraction opening; at least two sealing strips II are arranged at the periphery of the lower glass; at least one sealing strip is arranged in a position, corresponding to the extraction opening, of the upper glass; the sealing strip I of the upper glass is inserted into one sealing strip II or between the sealing strips II; the peripheries of the upper glass and the lower glass are welded together through low-temperature glass solder in an edge sealing furnace under the normal pressure; the extraction opening is sealed automatically in a vacuum furnace through metal solder. According to the invention, the process of the preparation method of the vacuum glass is simple; vacuum glass and tempered glass prepared through the preparation method can overcome the defects in the prior art; the airtightness of the vacuum glass is guaranteed; the strength, the thermal insulation performance and sound insulation performance of the vacuum glass are improved.

Description

technical field [0001] The invention relates to the technical field of glass deep processing, in particular to a vacuum glass with edge sealing and sealing with a sealing strip and a manufacturing method thereof. [0002] Background technique [0003] Vacuum glass is a new type of energy-saving glass. Vacuum glass can not only solve the "breathing" problem of insulating glass used in large quantities, but also has good heat and sound insulation performance, high wind pressure resistance, small thickness and long service life. advantage. Vacuum glass is generally composed of two to three pieces of glass, a cavity is formed between two adjacent pieces of glass, and an edge sealing structure is arranged around the glass, and the cavity is evacuated to form a vacuum layer. Vacuum glass can be divided into two types according to the way of forming the vacuum layer. One is the vacuum glass without air extraction port. The edge sealing of this vacuum glass is carried out in a vac...
