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 metal vacuum composite heat-insulation plate with edge sealed by a seal strip comprises a housing, at least two core plates and a vacuum cavity and is characterized in that the housing is a low-carbon steel plate, the core plates are located in the vacuum cavity and provides additional strength for the housing, the vacuum cavity is a closed cavity formed by welding the housing 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, and the low-carbon steel plate is matched with the coefficient of thermal expansion of the glass solder. The sealing is automatic sealing performed by utilizing an air exhaust opening pre-formed in the housing and a low-temperature solder in a vacuum furnace according to a liquid seal principle, the low-temperature solder includes low-temperature metal and an alloy solder, and a support is arranged between the core plates. 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.

Description

technical field [0001] The invention relates to the technical field of building energy saving, in particular to a metal vacuum composite heat insulation board with sealing strip edge sealing 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 ...
