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 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.

Embodiment 1

[0046] Embodiment 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 on...

Embodiment 2

[0047] 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. , drying treatment; secondly, print and prepare the sealing strip 5 on the lower surface peri...

Abstract

The invention relates to planar vacuum glass edge-sealed and port-sealed by using sealing strips and sealing grooves. The vacuum glass comprises upper glass and lower glass which are planar glass. An air-exhaust port is provided on the upper glass. Sealing strips are provided on the periphery of the upper glass and on the periphery of the air-exhaust port. Sealing grooves and sealing strips are provided on the periphery of the lower glass and at the place corresponding to the air-exhaust port. The peripheries of the upper glass and the lower glass are welded together by using a low-temperature glass solder under normal pressure in an edge-sealing furnace. The air-exhaust port is automatically sealed by using a metal solder in a vacuum furnace. A sealed vacuum layer is formed between the upper glass and the lower glass. Supporters arranged in a lattice pattern is provided in the vacuum layer. The vacuum glass and the preparation method thereof have simple process. The prepared vacuum glass and tempered vacuum glass can overcome defects of prior arts. Air-tightness of vacuum glass can be effectively endured. Strength, thermal insulation performance and sound insulation performance of the vacuum glass can be enhanced.

Description

technical field [0001] The invention relates to the technical field of glass deep processing, in particular to a planar vacuum glass with sealing strip groove edge sealing and sealing 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 exhaust port. The edge sealing of this vacuum glass is carried out in a vac...
