Embodiment 1

[0032] Embodiment 1: see figure 1, the glass-welded metal vacuum composite board is composed of a shell 1, a core plate 2, a vacuum chamber 3 and a support 4, the shell 1 is composed of a low-carbon steel plate with a thickness of 0.3-1.0mm; the core plate 2 is a metal plate, a 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.; support 4 is made of metal, ceramics, glass or high polymer, using printing, printing , spraying, mechanical placement, etc. are distributed between the core boards 2 in a lattice, the support height of the support 4 is preferably 0.15-1.0mm, and the diameter of the support point is preferably 0.3-1.0mm. The manufacturing method of the glass-welded metal vacuum composite panel is as follows: First, two low-carbon steel plates with the same size and a thickness of 0.3 mm are cut to make the shell 1, and the two low-carbon steel plates are folded and fo...

Embodiment 2

[0033] Example 2: See Example 1 and figure 2 , is basically the same as Example 1, except that the low-carbon steel plate forming the shell 1 is directly stamped out a sealing groove for edge sealing during stamping, and glass solder is placed in the sealing groove.

Abstract

The invention discloses a glass welded metal vacuum composite plate. The glass welded composite vacuum insulation board comprises a shell, core veneers and a vacuum cavity, and is characterized in that the shell is made from either 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 and are used for providing additional strength to the shell to ensure the smoothness of the shell at barometric pressure; the vacuum cavity is hermetically sealed by using 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, the number of the core veneers is at least two, and a support is arranged between every two core veneers and is separately made or directly formed on the core veneers. A production method of the glass welded metal vacuum composite plate provided by the invention is simple in process, the air-tightness of the vacuum cavity of the metal vacuum composite plate can be effectively ensured, the service life of the metal vacuum composite plate can be prolonged, and the strength, heat insulation, sound insulation, fire resistance and decorative function 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 vacuum composite 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 ...
