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 metal composite vacuum heat-insulation plate with the edge sealed by a seal strip comprises a face plate, a connecting layer and a vacuum cavity and is characterized in that the face plate is a metal plate or a metal composite plate, 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 metal composite vacuum heat-insulation plate is simple in process, the manufactured double-vacuum-layer metal composite vacuum heat-insulation plate can overcome the shortcomings of existing heat preservation plates and vacuum heat-insulation plates, and strength and heat-insulation, sound-insulation and fireproof performance can be improved.

Description

technical field [0001] The invention relates to the technical field of building energy conservation, in particular to a double-vacuum-layer metal composite vacuum insulation board with sealing strip edge sealing and a manufacturing method thereof. Background technique [0002] my country's building energy consumption has accounted for more than 1 / 3 of the energy consumption of the whole society, and it is increasing year by year. The use of thermal insulation building materials is one of the main means to reduce building energy consumption. At present, many materials used for building exterior wall insulation are Class B insulation materials, such as polystyrene, polyurethane, foam rubber and other organic materials. These organic materials have poor heat resistance and are easy to burn. A large amount of toxic smoke can accelerate the spread of the fire; at the same time, organic materials will shrink during a fire, producing burning droplets, causing the tiles on the insul...
