Embodiment 1

[0040] Embodiment 1: see figure 1 The glass-welded metal composite vacuum panel is composed of a panel 1, a connecting layer 2, a vacuum chamber 3 and a support 4. The panel 1 is composed of a thin metal plate such as a stainless steel plate or an aluminum alloy plate with a thickness of 0.2-1.5mm; the connecting layer 2 For high temperature resistant adhesives, high temperature resistant phenolic resin adhesives, epoxy resin adhesives, silicone resin adhesives, polyimide and other organic adhesives, as well as commonly used inorganic adhesives or organic-inorganic composite adhesives, etc., which can be cured at room temperature or high temperature can be selected; Cavity 3 is welded by low-carbon steel plates with a thickness of 0.3-1.0mm; support 4 is made of metal, ceramics, glass or polymer, and is distributed in a lattice by printing, printing, spraying, mechanical layout, etc. In the vacuum chamber 3, the supporting height of the support 4 is preferably 0.15-1.0 mm, and...

Embodiment 2

[0041] Example 2: See Example 1 and figure 2 , is basically the same as Example 1, except that the low-carbon steel plate forming the vacuum chamber 3 is directly punched out of the support 4 and sealing grooves for edge sealing during stamping, and glass solder is placed in the sealing grooves.

Abstract

The invention discloses a glass welded metal composite vacuum plate. The vacuum plate comprises a panel, a connecting layer and a vacuum cavity, and is characterized in that the panel is made from a a metal plate, the panel and the vacuum cavity are integrally connected by the connecting layer, the panel and / or the connecting layer are used for providing additional strength to the vacuum cavity to ensure the smoothness of the vacuum cavity in barometric pressure, and the vacuum cavity is formed by welding low carbon steel plates by a glass solder in the vacuum furnace at high vacuum and high temperature; the coefficients of thermal expansion of the low carbon steel plates and the glass solder are matched, and a support is arranged in the vacuum cavity and is separately made or directly formed in the vacuum cavity. A production method of the metal composite vacuum plate provided by the invention is simple in process, the defects of an existing insulation board and a vacuum insulated panel can be overcome by the prepared glass composite vacuum plate, the air-tightness of the vacuum cavity of the metal composite vacuum plate can be effectively ensured, the service life of the metal composite vacuum plate can be prolonged, and the strength, heat insulation, sound insulation and fire resistance can be enhanced.

Description

technical field [0001] The invention relates to the technical field of building energy conservation, in particular to a glass-welded 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 insulation materials ...
