Problems solved by technology

At present, many materials used for building exterior wall insulation are Class B insulation materials, such as polystyrene, polyurethane, foam rubber and other organic materials. These organic materials have poor heat resistance and are easy to burn. A large amount of toxic smoke can accelerate the spread of the fire; at the same time, organic materials will shrink during a fire, producing burning droplets, causing the tiles on the insulation layer to fall off, which may cause secondary fires and secondary fires. harm, so the relevant state departments explicitly prohibit the use of organic insulation materials for external wall insulation, especially in high-rise buildings and public buildings
Among the thermal insulation materials whose combustion performance reaches the A-level standard, inorganic materials represented by mineral wool and rock wool are mainly used. However, the existing domestic products have a large gap with the requirements of architectural applications in terms of w

Example Embodiment

[0037] With reference to the attached drawings, the metal vacuum composite insulation board with getter is composed of the shell 1, the core material 2 and the core board 3. The shell 1 is made of stainless steel plate, stainless iron plate, electroplated tin plate, and plated with a thickness of 0.15-1.5mm. It is composed of thin metal plates such as zinc plate or aluminum alloy plate; the core material 2 is glass fiber, pearl sand, perlite, vermiculite, aerogel, etc., and the getter 6 is placed in the core material 2, preferably the core material 2 Drying, plastic bag packaging, pre-vacuuming, etc.; core plate 3 is a metal plate, glass plate, ceramic plate or high temperature resistant polymer plate, preferably 3-5mm toughened glass plate or 1-2mm aluminum alloy plate or The high-temperature-resistant plastic plate is directly placed in the vacuum chamber; the exhaust port 4 is composed of an exhaust nozzle and a metal cover directly punched out of the upper metal plate of the...

Abstract

The invention discloses a metal vacuum composite insulation plate with a getter. The metal vacuum composite insulation plate comprises a shell, a core material, a core plate and a vacuum cavity, and is characterized in that the shell is a metal plate or a metal composite plate, wherein the core material is positioned in the vacuum cavity for providing additional strength to the shell and guaranteeing the flatness of the shell under atmospheric pressure; the vacuum cavity is a closed cavity formed by performing the welding edge sealing under normal pressure and the high-temperature opening sealing under vacuum for the shell; the opening sealing is a step that an extraction opening prefabricated in the shell is automatically sealed in a vacuum furnace by using a low-temperature solder according to a liquid sealing principle; and the getter is arranged in the vacuum cavity. A preparation method of the metal vacuum composite insulation plate is simple in process; and the prepared metal vacuum composite insulation plate with the getter can overcome the defects of a traditional insulation plate and a traditional vacuum insulation plate, and can be improved in strength, and heat insulation, sound insulation, fire prevention and decoration functions.

Description

technical field [0001] The invention relates to a vacuum heat insulation panel, in particular to a metal vacuum composite heat insulation panel with a getter and a manufacturing method thereof. Background technique [0002] my country's building energy consumption has accounted for more than 1 / 3 of the energy consumption of the whole society, and it is increasing year by year. The use of thermal insulation building materials is one of the main means to reduce building energy consumption. At present, many materials used for building exterior wall insulation are Class B insulation materials, such as polystyrene, polyurethane, foam rubber and other organic materials. These organic materials have poor heat resistance and are easy to burn. A large amount of toxic smoke can accelerate the spread of the fire; at the same time, organic materials will shrink during a fire, producing burning droplets, causing the tiles on the insulation layer to fall off, which may cause secondary fir...
