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

Abstract

The invention discloses a glass welded double-vacuum-layer metal composite vacuum plate with a mounting hole. The double-vacuum-layer 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 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 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 clapboard is arranged in the vacuum cavity and is used for dividing the vacuum cavity into double vacuum layers in which supports are arranged. A production method of the double-vacuum-layer 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 relates to the technical field of building energy saving, in particular to a double-vacuum-layer metal composite vacuum panel with installation holes welded to glass 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 ...
