Double-vacuum-layer composite vacuum panel with sealing strips and mounting holes and manufacturing method thereof
A double-vacuum-layer composite vacuum panel with sealing strips and mounting holes comprises a surface plate, a core plate and a vacuum chamber and is characterized in that the mounting holes are combined with pumping holes, the surface plate is fixed to the outer upper surface of the vacuum chamber, the core plate is arranged at the inner bottom of the vacuum chamber, the surface plate and/or the core plate provide the vacuum chamber with additional strength, the vacuum chamber is a closed chamber formed by a low-carbon steel plate subjected to glass soldering edge sealing at atmospheric pressure and high temperature and high-temperature opening sealing in vacuum, welding portions of the edge of the low-carbon steel plate are provided with the sealing strips, the coefficient of thermal expansion of the low-carbon steel plate is matched with that of glass solder, a separation plate separating the vacuum chamber into two to form double vacuum layers is arranged in the vacuum chamber, and supporting members are arranged in the vacuum layers. A manufacturing method of the double-vacuum-layer composite vacuum panel with the sealing strips and the mounting holes is simple in process. The manufactured double-vacuum-layer composite vacuum panel can overcome the deficiencies of existing insulation boards and vacuum insulation panels and the strength, thermal insulation, sound insulation and fireproof performance and decorative functions can be improved.
