Glassed welded glass composite vacuum insulation board and production method thereof
The invention discloses a glassed welded glass composite vacuum insulation board. The vacuum insulation board comprises a panel, a connecting layer and a vacuum cavity, and is characterized in that the panel is made from a glass plate, the panel and the vacuum cavity are internally connected by the connecting layer, the vacuum cavity is a closed cavity formed by carrying out glass welding sealed edges at constant pressure and high temperature and sealing at high temperature in vacuum to low carbon steel plates and the coefficients of thermal expansion of the low carbon steel plate and the glass solder are matched; the sealing is that an extraction opening preformed in the vacuum cavity is 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 glassed welded glass composite vacuum insulation board provided by the invention is simple in process, the defects of an existing insulation board and a vacuum insulated panel can be overcome, the air-tightness of the vacuum cavity of the glass composite vacuum insulation board can be effectively ensured, the service life of the glass composite vacuum insulation board can be prolonged, and the strength, heat insulation, sound insulation and fire resistance can be enhanced.
