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.

Abstract

The invention relates to vacuum glass with edge and port sealed by using sealing strips and sealing grooves. The vacuum glass comprises upper glass and lower glass which are convex glass or 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 places corresponding to the air-exhaust port. The peripheries of the upper and lower glass are automatically welded together in an edge-sealing furnace under normal pressure by using a low-temperature glass solder. 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. The vacuum layer is provided with or without supporters in a lattice arrangement. The vacuum glass and the preparation method thereof provided by the invention have a simple process. Prepared vacuum glass and tempered vacuum glass can overcome defects of prior arts. Air-tightness of the vacuum glass can be ensured. Strength, thermal insulation performance and sound insulation performance of the glass can be effectively ensured.

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 of sealing strips and grooves 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 v...
