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

Embodiment

[0039] Example: see figure 1 , double-vacuum-layer metal vacuum composite panel with sealing strip edge sealing is composed of shell 1, core plate 2, vacuum chamber 3, support 4 and partition 5, shell 1 is composed of low-carbon steel plate with a thickness of 0.3-1.0mm; core plate 2 is a metal plate, a ceramic plate, a glass plate, a plastic plate or a composite plate, etc., preferably an aluminum alloy plate with a thickness of 1-2mm or a tempered glass plate with a thickness of 3-5mm; Directly welded together, so that the vacuum chamber 3 forms two independent vacuum layers; the support 4 is made of metal, ceramics, glass or polymer, and is distributed in a dot matrix by printing, printing, spraying, mechanical layout, etc. On the upper and lower surfaces of the partition 5, the supporting height of the support 4 is preferably 0.15-1.0 mm, and the diameter of the supporting point is preferably 0.3-1.0 mm. The method of making the double-vacuum-layer metal vacuum composite ...

Abstract

A double-vacuum-layer metal vacuum composite plate with the 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 or a low-carbon steel composite plate, the core plates are located in the vacuum cavity formed through seal welding of the housing, the core plates provide additional strength for the housing and ensure the smoothness of the housing under atmospheric pressure, the vacuum cavity is welded and sealed by utilizing a glass solder in a vacuum furnace under 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, 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 and are independently manufactured or are directly formed on the core plate or the partition plate. A manufacturing method of the double-vacuum-layer metal vacuum composite 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 double-vacuum-layer metal vacuum composite 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 orga...
