Abstract:
1. A compound sealing method for vacuum glass, realizing the air-tight joint between compounded glass plates in a preset position of the glass plate by using a metal brazing technology, further comprising the following steps: a) respectively preparing a metallized layer bonded with the glass plate body on a preset sealing area surface of each glass plate to be compounded, the preparation process is: a1) preparing a metal paste coating on the surface of the glass plate in the preset sealing area, said metal paste comprises a sintering temperature in the range of 580° C. to 820° C.; a2) heating the glass plate to sinter the metal paste coating into the metallized layer bonded with the glass plate body; b) carry out tempering or semi-tempering or heat strengthening on the glass plate; c) joining the metallized layers in the corresponding sealing areas of every two compounded glass plates by using a metal brazing technology to realize the air-tight joint between the two glass plates in the sealing area wherein the sintering temperature of the sintering technology in step a2) is in the tempering range of the glass plate, and the glass plate is directly subjected to quenching and cooling after being processed by the sintering technology to complete the tempering treatment of the glass plate.
