Glass composite vacuum panel with sealing strips and getter and manufacturing method thereof

Abstract

A glass composite vacuum panel with sealing strips and a getter comprises a surface plate, a connecting layer and a vacuum chamber and is characterized in that the surface plate is a glass plate, the connecting layer connects the surface plate and the vacuum chamber as a whole, the vacuum chamber is a closed chamber formed by a low-carbon steel plate subjected to glass soldering edge sealing at atmospheric pressure and high temperature and high-temperature opening sealing in vacuum, welding portions of the edge of the low-carbon steel plate are provided with the sealing strips, the opening sealing is the automatic sealing of pumping holes preformed in the vacuum chamber with low-temperature solder in a vacuum furnace according to the principle of liquid seal, and supporting members and the getter are arranged in the vacuum chamber. A manufacturing method of the glass composite vacuum panel with the sealing strips and the getter is simple in process. The glass composite vacuum panel with the getter can effectively ensure the gas tightness of the vacuum chamber, the service life can be prolonged, and the strength and thermal 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 with a sealing strip and a getter 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 ...

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
