Glass welded stone composite vacuum insulation board and production method thereof
The invention discloses a glass welded stone composite vacuum insulation board. The stone composite vacuum insulation board comprises a panel, a connecting layer 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/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 a closed cavity formed by carrying out glass welding and sealing at constant pressure and high temperature and sealing at high temperature in vacuum to low carbon steel plates; 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, the low temperature solder comprises a low temperature metal and an alloy solder, and a support is arranged in the vacuum cavity. A production method of the stone composite vacuum insulation board provided by the invention is simple in process, the defects of an existing insulating plate and a vacuum insulated panel can be overcome, the air-tightness of the vacuum cavity of the stone composite vacuum insulation board can be effectively ensured, the service life of the stone composite vacuum insulation board can be prolonged, and the strength, heat insulation, sound insulation and fire resistance can be enhanced.
