Glass welded stone composite vacuum plate and production method thereof
The invention discloses a glass welded stone composite vacuum plate. The glass welded stone composite vacuum plate comprises a panel, a connecting plate and a vacuum cavity, and is characterized in that the panel is made from either a natural stone or an artificial stone, the panel and the vacuum cavity are integrally formed by the connecting layer, the panel and/or the connecting layer are used for providing additional strength to the vacuum cavity so as to ensure the smoothness of the vacuum cavity at barometric pressure and the vacuum cavity is formed by welding low carbon steel plates in a furnace cavity by virtue of a glass solder at high vacuum and high temperature; the coefficients of thermal expansion of the low carbon steel plate and the glass solder are matched, and a support is arranged in the vacuum cavity and is separately made or directly formed in the vacuum cavity. A production method of the glass welded stone composite vacuum plate provided by the invention is simple in process, the air-tightness of the stone composite vacuum plate can be effectively ensured, the service life of the stone composite vacuum plate can be prolonged, and the strength, heat insulation, sound insulation and fire resistance can be enhanced.
