Glass composite vacuum plate with edge sealed by seal strip and manufacturing method thereof

Abstract

A glass composite vacuum plate with the edge sealed by a seal strip comprises a face plate, a connecting layer and a vacuum cavity and is characterized in that the face plate is a glass plate, the connecting layer enables the face plate and the vacuum cavity to be connected to form a whole, the vacuum cavity is formed by welding a low-carbon steel plate in a vacuum furnace by utilizing a glass solder under the high vacuum and high temperature, the seal strip is arranged at the welding position of the edge portion of the low-carbon steel plate, the low-carbon steel plate is matched with the coefficient of thermal expansion of the glass solder, and a support is arranged in the vacuum cavity and is independently manufactured or is directly formed on the vacuum cavity. A manufacturing method of the glass composite vacuum plate is simple in process, the manufactured glass composite vacuum plate can overcome the shortcomings of existing heat preservation plates and vacuum heat-insulation plates, the air impermeability of the vacuum cavity of the glass composite vacuum plate can be effectively ensured, the service life of the glass composite vacuum plate can be prolonged, and strength and heat-insulation, sound-insulation and fireproof performance can be improved.

Description

technical field [0001] The invention relates to the technical field of building energy conservation, in particular to a glass composite vacuum panel sealed with sealing strips 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 insulat...

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
