Glass welded metal composite vacuum plate welded with mounting hole and production method thereof

Abstract

The invention discloses a glass welded metal composite vacuum plate welded with a mounting hole. The glass welded metal composite vacuum plate comprises a panel, a connecting layer and a vacuum cavity, and is characterized in that the mounting hole and an extraction opening are combined, the mounting hole penetrates through the entire 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, and the vacuum cavity is a closed cavity formed by carrying out glass welding at constant temperature and high temperature and sealing at constant pressure to a low carbon steel plate; the sealing is that an extraction opening preformed in the vacuum cavity is automatically sealed by a low temperature solder in a vacuum furnace according to a liquid sealing theory, and a support is arranged in the vacuum cavity. A production method of the glass welded metal composite vacuum plate 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.

Description

Technical field [0001] The invention involves the field of energy -saving technology in the building, especially a metal composite vacuum board and its production method with a glass welding with installation holes. Background technique [0002] At present, the materials used in the exterior wall of the building are divided into A -level insulation materials and B -level insulation materials. The fire resistance performance of A -level insulation materials is good, but its insulation performance and water resistance performance are lower than the B -level insulation material, and there are high prices.Problems such as complicated construction technology; B -level insulation materials have the advantages of low cost, good thermal insulation performance, and mature construction technology, but their durability, poor thermal resistance, and combustion.And it can accelerate the spread of fire, so organic insulation materials are prohibited in high -rise buildings and public buildings...

AI Technical Summary

Problems solved by technology

[0003] The patent applicant disclosed a series of vacuum panels and their production methods in July 2013, although they solved the problems of fire prevention, heat preservation and service life of existing thermal insulation materials However, since the metal plates are directly welded together, there are obvious cold bridges at the edges, making the thermal insulation performance not optimal
