Abstract

A double-vacuum-layer metal vacuum composite panel with sealing strips and mounting holes comprises a housing, a core plate and a vacuum chamber and is characterized in that the mounting holes are combined with pumping holes, the housing is a low-carbon steel plate, the core plate is arranged in the vacuum chamber to provide the housing with additional strength to ensure the smoothness of the housing at atmospheric pressure, the vacuum chamber is a closed chamber formed by the housing 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 opening sealing is the automatic sealing of the pumping holes preformed in the housing with low-temperature solder in a vacuum furnace according to the principle of liquid seal, 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 metal vacuum composite panel with the sealing strips and the mounting holes is simple in process. The manufactured double-vacuum-layer metal vacuum composite 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.

Description

technical field

[0001] The invention relates to the technical field of building energy saving, in particular to a double-vacuum-layer metal vacuum composite board with sealing strips and installation holes 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 ...
