Embodiment 1

[0036] Embodiment 1: see figure 1 , the glass-welded double-vacuum-layer metal vacuum composite board is composed of a shell 1, a core plate 2, a vacuum chamber 3, a support 4 and a partition 5, the shell 1 is made of a low-carbon steel plate with a thickness of 0.3-1.0mm; the core plate 2 is Metal plate, ceramic plate, glass plate, plastic plate or composite plate, etc., preferably 1-2mm thick aluminum alloy plate or 3-5mm thick tempered glass plate, etc.; the partition 5 can be made of low-carbon steel plate, which is directly welded to the shell 1 Together, the vacuum chamber 3 forms two independent vacuum layers; the support 4 is made of metal, ceramics, glass or polymer, and is distributed on the partition in a lattice by printing, printing, spraying, mechanical placement, etc. On the upper and lower surfaces of 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 manufacturing method ...

Embodiment 2

[0037] 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 and placed directly in the vacuum chamber 3, and the low-carbon steel plate forming the shell 1 is directly punched out of a sealing groove for edge sealing during stamping and forming, sealing Glass solder is placed in the groove.

Abstract

The invention discloses a glass welded double-vacuum-layer metal vacuum composite plate. The double-vacuum-layer metal vacuum composite plate comprises a shell, core veneers and a vacuum cavity, and is characterized in that the shell is made from low carbon steel plates or low carbon steel composite plates, the core veneers are located in the vacuum cavity formed by hermetically welding the shell, the number of the core veneers is at least two and the core veneers are used for providing additional strength to the vacuum cavity to ensure the smoothness of the vacuum cavity at barometric pressure and the vacuum cavity is hermetically sealed by a glass solder at high vacuum and high temperature in a vacuum furnace; 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, and the strength, heat insulation, sound insulation, fire resistance and decorative function 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 vacuum composite board 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...
