Embodiment 1

[0043] Embodiment 1: see figure 1 , the glass-welded double-vacuum-layer metal composite vacuum panel is composed of a panel 1, a connecting layer 2, a vacuum chamber 3, a support 4 and a partition 5, and the panel 1 is made of a thin metal such as a stainless steel plate or an aluminum alloy plate with a thickness of 0.2-1.5mm. board structure; the connecting layer 2 is a high temperature resistant adhesive, which can be selected from room temperature or high temperature cured high temperature resistant phenolic resin adhesive, epoxy resin adhesive, silicone resin adhesive and polyimide and other organic adhesives, as well as commonly used inorganic adhesives or organic adhesives. Inorganic composite adhesives, etc.; the vacuum chamber 3 is welded by low-carbon steel plates with a thickness of 0.3-1.0mm, and the same plate can be used for the partition 5, which is directly welded with the vacuum chamber 3, so that the vacuum chamber 3 forms two independent Vacuum layer; the s...

Embodiment 2

[0044] Example 2: See Example 1 and figure 2 , which is basically the same as in Example 1, except that the separator 5 is made of an aluminum alloy plate, which is directly placed in the vacuum chamber 3, and the low-carbon steel plate forming the vacuum chamber 3 is directly punched out of the support 4 and used for edge sealing during stamping and forming. The sealing groove is placed in the sealing groove, and the glass solder is placed in the sealing groove.

Abstract

The invention discloses a glass welded double-vacuum-layer metal composite vacuum plate. The double-vacuum-layer metal composite vacuum plate comprises a panel, a connecting layer and a vacuum cavity, and is characterized in that the panel is made from a metal plate, the panel and the vacuum cavity are integrally formed by the connecting layer, the vacuum cavity is formed by welding thin low carbon steel plates, and the panel and/or the connecting layer are used for providing additional strength to the vacuum cavity; the vacuum cavity is hermetically sealed by a glass solder in a vacuum furnace at high vacuum and high temperature, the coefficients of thermal expansion of the low carbon steel plate and the glass solder are matched, a clapboard is arranged in the vacuum cavity and is used for dividing the vacuum cavity into double vacuum layers, and supports are arranged in the vacuum layers and are separately made or directly formed on the vacuum cavity or the clapboard. A production method of the double-vacuum-layer composite vacuum plate provided by the invention is simple in process, the defects of an existing insulation board and an existing vacuum insulated panel can be overcome, and the strength, heat insulation, sound insulation and fire resistance can be improved.

Description

technical field [0001] The invention relates to the technical field of building energy saving, in particular to a glass-welded double-vacuum-layer metal 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 insulat...
