Metal vacuum insulation panel with sealing strips and getter and manufacturing method thereof

Abstract

A metal vacuum insulation panel with sealing strips and a getter comprises a housing, a core material and a vacuum chamber and is characterized in that the housing is a low-carbon steel plate or a low-carbon steel composite plate, the core material is arranged in the vacuum chamber to provide the housing with additional strength to ensure the smoothness of the housing at atmospheric pressure, the vacuum chamber is a closed chamber formed by the housing 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 coefficient of thermal expansion of the low-carbon steel plate is matched with that of glass solder, the opening sealing is the automatic sealing of pumping holes preformed in the housing with low-temperature solder in a vacuum furnace according to the principle of liquid seal, and the getter is arranged in the vacuum chamber. A manufacturing method of the metal vacuum insulation panel with the sealing strips and the getter is simple in process. The manufactured metal vacuum insulation panel with the getter can overcome the deficiencies of existing insulation boards and vacuum insulation panels and the strength, thermal insulation, sound insulation and fireproof performance and decorative functions can be improved.

Description

technical field

[0001] The invention relates to a vacuum heat insulation panel, in particular to a metal vacuum heat insulation 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 insulation mate...
