Metal vacuum composite heat-insulation plate with edge sealed by seal strip and manufacturing method thereof
A metal vacuum composite heat-insulation plate with edge sealed by a seal strip comprises a housing, a core material, a core plate and a vacuum cavity and is characterized in that the housing is a low-carbon steel plate or a low-carbon steel composite plate, the core material and the core plate are located in the vacuum cavity formed through sealing and welding of the housing, the core plate and/or the core material provide/provides additional strength for the housing and ensure/ensures the smoothness of the housing under atmospheric pressure, 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, and the low-carbon steel plate is matched with the coefficient of thermal expansion of the glass solder. A manufacturing method of the metal vacuum composite heat-insulation plate is simple in process, the manufactured metal vacuum composite heat-insulation plate can overcome the shortcomings of existing heat preservation plates and vacuum heat-insulation plates, and strength, heat-insulation, sound-insulation and fireproof performance and a decorative function can be improved.
