Glass welded glass composite vacuum plate welded with mounting hole and production method thereof

Abstract

The invention discloses a glass welded glass composite vacuum plate welded with a mounting hole. The glass welded glass composite vacuum plate comprises a panel, core veneers and a vacuum cavity, and is characterized in that the mounting hole and an extraction opening are combined, the mounting hole penetrates through the entire core veneers, the panel is fixed on the upper surface of the vacuum cavity by either a welding way or a gluing way and the core veneers are placed at the inner bottom of the vacuum cavity; the panel and / or the core veneers are used for providing additional strength to the vacuum cavity to ensure the smoothness of the vacuum cavity at barometric pressure, the vacuum cavity is a closed cavity formed by carrying out glass welding at constant temperature and high temperature and sealing at constant pressure to a low carbon steel plate, the sealing is that an extraction opening preformed in the vacuum cavity is automatically sealed by a low temperature solder in a vacuum furnace according to a liquid sealing theory, and a support is arranged in the vacuum cavity. A production method of the glass composite vacuum plate provided by the invention is simple in process, the defects of an existing insulation board and an existing vacuum insulated panel can be overcome, and the strength, heat insulation, sound insulation, fire resistance and decorative function can be improved.

Description

technical field [0001] The invention relates to the technical field of building energy saving, in particular to a composite vacuum panel with installation holes welded by glass and a manufacturing method thereof. Background technique [0002] At present, the materials used for building exterior wall insulation are divided into A-grade thermal insulation materials and B-grade thermal insulation materials. A-grade thermal insulation materials have good fire resistance, but their thermal insulation performance and water resistance are lower than B-grade thermal insulation materials, and there are high prices. Complex construction technology and other issues; B-grade thermal insulation materials have the advantages of low cost, good thermal insulation performance, and mature construction technology, but their durability is not good, heat resistance is poor, and they are easy to burn. Moreover, it can accelerate the spread of fire, so it is forbidden to use organic thermal insula...
