Problems solved by technology

[0003] 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 October, 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.
In addition, it is difficult to achieve the required height for sealing strips and supports made of low-temperature glass powder or low-temperature glass solder. When tempering, the sealing strip and the support are melted at high temperature, and its height is further reduced

Embodiment 1

[0057] Example 1: see figure 1 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, the low-emissivity glass is selected as the lower glass 2, a through hole is drilled at the corner of the upper glass 1 as the air outlet 3, and a sealing groove is provided around the periphery of the lower glass 2 and at the corresponding place of the air outlet 3 6, and carry out edge grinding, chamfering, cleaning and drying, and use screen printing technology to print sealing strips on the periphery of the upper glass 1, the periphery of the air inlet 3, and the periphery of the upper sealing groove 6 of the lower glass 2, and at the same time print the sealing strip on the At least one p...

Embodiment 2

[0058] Example 2: see figure 2 , the vacuum glass is composed of upper glass 1, middle glass 9 and lower glass 2, at least the upper and lower glass of the three pieces of glass are tempered glass or semi-tempered glass, wherein the lower glass 2 or\ and middle glass 9 are also low-emissivity glass, which The production method is as follows: First, cut three pieces of flat glass according to the shape and size of the vacuum glass to be produced, and drill a through hole on the upper glass 1 and the middle glass 9 respectively to form the air inlet 3, wherein the upper glass 1 The through hole is larger than the through hole on the middle glass 9, and the sealing groove 6 is set on the upper surface periphery of the middle glass 9 and the lower glass 2 and the periphery of the air suction port 3 and the corresponding positions, and the three glasses are ground, chamfered, and cleaned. , dry treatment; secondly, utilize toughened glass ink to print and prepare sealing strip 5 o...

Abstract

The invention discloses planar toughened vacuum glass provided with an extraction opening with edges being sealed by sealing strips and sealing grooves. The planar toughened vacuum glass is characterized in that upper glass and lower glass are planar toughened glass; the upper glass is provided with the extraction opening; the sealing strips are arranged on the peripheries of the upper glass and the extraction opening, and the sealing strips and the sealing grooves are arranged on the periphery of the lower glass and corresponding positions of the extraction opening; the peripheries of the upper glass and the lower glass are welded together in an edge-sealing furnace under a normal pressure through a glass solder; the extraction opening is automatically enclosed in a vacuum furnace by using a metal solder; an enclosed vacuum layer is formed between the upper glass and the lower glass; one or two layers of support objects are arranged in the vacuum layer; the sealing strips and / or the support objects consist of toughened glass ink and a high polymer; the high polymer is prepared into a prepolymer firstly; after toughening of the glass, the prepolymer is prepared on the glass or the toughened glass ink; the prepolymer is cured into an elastomer at a room temperature or a high temperature; the prepolymer or the elastomer can automatically adapt to the height change of the vacuum layer; and the elastomer exhausts contained volatile gas at a high temperature and in high vacuum.

Description

technical field [0001] The invention relates to the technical field of glass deep processing, in particular to a flat tempered vacuum glass with a sealing strip groove edge sealing and an air suction port and a manufacturing method thereof. Background technique [0002] 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 exhaust port. The edge sealing of this vacuum glass is carried o...
