Vacuum glass panel and manufacturing method of same

摘要

Disclosed are a vacuum glass panel and a manufacturing method of the same. The vacuum glass panel according to the present invention includes a first glass plate, a second glass plate facing the first glass plate with a vacuum space therebetween, an edge of the second glass plate being in contact with the first glass plate, and a plurality of spacers disposed between the first glass plate and the second glass plates to separate the first glass plate and the second glass plate from each other. The plurality of spacers are formed of a glass including alumina (Al2O3) particles and silica (SiO2) particles.

1. A method of manufacturing an insulated vacuum glass panel, the method comprising:
preparing a paste for a spacer, wherein the paste includes at least one of a water glass and silica sol, an alumina (Al2O3) powder, a silica (SiO2) powder, and a plasticizer, but does not include a frit; screen-printing the paste on one of a first glass plate and a second glass plate and drying the paste to form a plurality of spacers; laminating the first glass plate and the second glass plate with the plurality of spacers therebetween; and welding edges of the first glass plate and the second glass plate such that the edge of first glass plate and the edge of second glass plate directly contact with each other without a frit and evacuating an internal space to form a vacuum space, wherein at least two torch parts are disposed at external sides of the edges of the first glass plate and the second glass plate due to the welding of the edges of the first glass plate and the second glass plate by melting the edges with heat from the at least two torch parts such that the at least two torch parts are disposed on opposite sides with the first glass plate and the second glass plate therebetween, and move in opposite directions, wherein the first glass plate and the second glass plate are formed of a square plate including a pair of first edges and a pair of second edges facing each other such that a first torch part and a second torch part are located at external sides of the pair of first edges, respectively, wherein the first torch part and the second torch part move in opposite directions to weld the pair of first edges, and wherein the at least two torch parts are slantly installed such that end parts toward the first glass plate and the second glass plate face upwards or downwards.
