Metal vacuum composite plate with edge sealed by seal strip and manufacturing method thereof
A metal vacuum composite plate with the edge sealed by a seal strip comprises a housing, at least two core plates and a vacuum cavity and is characterized in that the housing is a low-carbon steel plate, the core plates are located in the vacuum cavity formed through seal welding of the housing, the vacuum cavity is welded and sealed by utilizing a glass solder in a vacuum furnace under high vacuum and high temperature, the seal strip is arranged at the welding position of the edge portion of the low-carbon steel plate, the coefficient of thermal expansion of the low-carbon steel plate is matched with that of the glass solder, and a support is arranged between the core plates and is independently manufactured or is directly formed on the core plates. A manufacturing method of the metal vacuum composite plate with the edge sealed by the seal strip is simple in process, the air impermeability of the vacuum cavity of the metal vacuum composite plate can be effectively ensured, the service life of the metal vacuum composite plate can be prolonged, and strength, heat-insulation, sound-insulation and fireproof performance and a decorative function can be improved.
