Glass welded double-vacuum-layer metal vacuum composite insulation board and production method thereof
The invention discloses a glass welded double-vacuum-layer metal vacuum composite insulation board. The double-vacuum-layer metal vacuum composite insulation board comprises a shell, core veneers and a vacuum cavity, and is characterized in that the shell is made from low carbon steel plates or low carbon steel composite plates, the core veneers are located in the vacuum cavity formed by hermetically welding the shell, the number of the core veneers is at least two and the core veneers are used for providing additional strength to the vacuum cavity 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 to the shell; the coefficients of thermal expansion of the low carbon steel plate and the glass solder are matched, a clapboard is arranged in the vacuum cavity and is used for dividing the vacuum cavity into double vacuum layers, and supports are arranged in the vacuum layers and are separately made or directly formed on the vacuum cavity or the clapboard. A production method of the double-vacuum-layer composite vacuum plate provided by the invention is simple in process, and the strength, heat insulation, sound insulation, fire resistance and decorative function can be improved.
