Abstract
The invention discloses a glass welded metal vacuum composite insulation board. The glass welded metal vacuum composite insulation board comprises a shell, core veneers and a vacuum cavity, and is characterized in that the shell is either low carbon steel plates or low carbon steel composite plates, the core veneers are located in the vacuum cavity and are used for providing 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 the shell at constant pressure and high temperature and sealing at high temperature in vacuum, the coefficients of thermal expansion of the low carbon steel plate and the glass solder are matched, the sealing is that an extraction opening preformed in the vacuum cavity is sealed by a low temperature solder in a vacuum furnace according to a liquid sealing theory, the number of the core veneers is at least two, and a support is arranged between every two core veneers. A production method of the glass welded metal vacuum composite 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 metal vacuum composite insulation board, 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 saving, in particular to a glass-welded metal vacuum composite heat insulation 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 insulation ...
