Problems solved by technology

[0003] The patent applicant disclosed a series of vacuum panels and their production methods in July 2013, although they solved the problems of fire prevention, heat preservation and service life of existing thermal insulation materials However, since the metal plates are directly welded together, there are obvious cold bridges at the edges, making the thermal insulation performance not optimal

Abstract

A double-vacuum-layer composite vacuum 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 vacuum cavity is formed by welding a thin 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 low-carbon steel plate is matched with the coefficient of thermal expansion of the glass solder, 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 plate is simple in process, 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 saving, in particular to a sealing strip edge-sealing double-vacuum-layer composite vacuum panel 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...
