Glass welded metal vacuum composite insulation board and production method thereof
The invention discloses a glass welded metal vacuum composite insulation board. The glass welded metal vacuum composite insulation board comprises a shell, core veneers and a vacuum cavity, and is characterized in that the shell is either low carbon steel plates or low carbon steel composite plates, the core veneers are located in the vacuum cavity and are used for providing additional strength to the shell to ensure the smoothness of the shell at barometric pressure; the vacuum cavity is a sealed cavity formed by welding and sealing the shell at constant pressure and high temperature and sealing at high temperature in vacuum, 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, the number of the core veneers is at least two, and a support is arranged between every two core veneers. A production method of the glass welded metal vacuum composite plate provided by the invention is simple in process, the defects of an existing insulation board and a vacuum insulated panel can be overcome by the prepared metal vacuum composite insulation board, and the strength, heat insulation, sound insulation, fire resistance and decorative function can be enhanced.
