Composite vacuum plate with edge sealed by seal strip and manufacturing method thereof

Abstract

A composite vacuum plate with the edge 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 vacuum cavity is formed by welding a low-carbon steel plate, the face plate and / or the core plate provide / provides additional strength for the vacuum cavity, the vacuum cavity is welded and sealed by utilizing a glass solder in a vacuum furnace under the 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 in the vacuum cavity and is independently manufactured or is directly formed on the inner wall of the vacuum cavity or the core plate. A manufacturing method of the composite vacuum plate is simple in process, the air impermeability of the vacuum cavity of the composite vacuum plate can be effectively ensured, the service life of the composite vacuum plate can be prolonged, and strength, heat-insulation, sound-insulation and fireproof performance and a decorative function can be improved.

Description

technical field [0001] The invention relates to the technical field of building energy conservation, in particular to a composite vacuum panel with edge sealing by sealing strips and a manufacturing method thereof. Background technique [0002] At present, the materials used for building exterior wall insulation are divided into A-grade thermal insulation materials and B-grade thermal insulation materials. A-grade thermal insulation materials have good fire resistance, but their thermal insulation performance and water resistance are lower than B-grade thermal insulation materials, and there are high prices. Complex construction technology and other issues; B-grade thermal insulation materials have the advantages of low cost, good thermal insulation performance, and mature construction technology, but their durability is not good, heat resistance is poor, and they are easy to burn. Moreover, it can accelerate the spread of fire, so it is forbidden to use organic thermal insu...
