Glass welded double-vacuum-layer metal composite vacuum insulation board and production method thereof
The invention discloses a glass welded double-vacuum-layer metal composite vacuum insulation board. The double-vacuum-layer metal composite vacuum insulation board comprises a panel, a connecting layer and a vacuum cavity, and is characterized in that the panel is made from either a metal plate or a metal composite plate, 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 at barometric pressure, the vacuum cavity is a closed cavity formed by carrying out glass welding at normal pressure and high temperature and sealing at high pressure to low carbon steel plates and 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; 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. A production method of the double-vacuum-layer metal composite vacuum insulation board provided by the invention is simple in process, the defects of an existing insulation board and an existing vacuum insulated panel can be overcome, and the strength, heat insulation, sound insulation and fire resistance can be improved.
