Double-vacuum-layer composite vacuum heat-insulation plate with edge sealed by seal strip and manufacturing method thereof
A double-vacuum-layer composite vacuum heat-insulation plate sealed by a seal strip comprises a face plate, a core plate and a vacuum cavity and is characterized in that the face plate is fixed to the upper surface outside the vacuum cavity in a welding or bonding mode, the core plate is arranged at the bottom of the inside of the vacuum cavity, the face plate and/or the core plate provide/provides additional strength for the vacuum cavity, the vacuum cavity is a closed cavity formed by welding a low-carbon steel plate and sealing the edge by utilizing a glass solder under the constant pressure and high temperature and performing high-temperature sealing under the vacuum condition, the seal strip is arranged at the welding position of the edge portion of the low-carbon steel plate, the sealing is automatic sealing performed by utilizing an air exhaust opening pre-formed in the vacuum cavity and a low-temperature solder in a vacuum furnace according to a liquid seal principle, a partition plate is arranged in the vacuum cavity and divides the vacuum cavity into two to form double vacuum layers, and supports are arranged in the vacuum layers. A manufacturing method of the double-vacuum-layer composite vacuum heat-insulation plate is simple in process, the manufactured double-vacuum-layer composite vacuum 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.
