Embodiment 1

[0029] Embodiment 1: see figure 1 , the glass-welded metal vacuum insulation panel consists of an outer shell 1 and a core material 2, the outer shell 1 is composed of a low-carbon steel plate with a thickness of 0.3-1.0mm; the core material 2 is glass fiber, pearl sand, perlite, vermiculite, airgel etc., the core material 1 is preferably dried, packed in a plastic bag, pre-vacuumized, and the like. The manufacturing method of the glass-welded metal vacuum insulation 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 formed by stamping; secondly, After drying pearl sand or perlite with a certain particle size in a continuous kiln, put it into a plastic bag and seal it after vacuuming to make it a core material with a small volume and a certain shape; Material 2 is put into the cavity of lower shell 1, and glass solder 3 is coated on the welding par...

Embodiment 2

[0030] 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 groove for edge sealing during stamping, and glass solder is placed in the groove.

Abstract

The invention provides a glass welded metal vacuum insulated panel. The glass welded metal vacuum insulated panel comprises a shell, a core material 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 material is located in the vacuum cavity formed by hermetically welding the shell and is used for providing the additional strength to the shell to ensure the smoothness of the shell at barometric pressure; the vacuum cavity is a sealed cavity formed by welding and sealing a glass solder at high vacuum and high temperature and the coefficients of thermal expansion of the low carbon steel plate and the glass solder are matched. A production method of the glass welded metal vacuum insulated panel provided by the invention is simple in process, the defects of an existing insulation board and an existing vacuum insulated panel can be overcome, 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 a vacuum insulation panel, in particular to a glass-welded metal vacuum insulation 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 for external wall insulat...
