preparation example Construction

[0041] In the present application, the preparation method of the getter for vacuum insulation panels preferably includes the following steps:

[0042] In the presence of a first protective gas, mixing the first powder and a desiccant to obtain a powder;

[0043] In the presence of the second protective gas, the powder is packaged into a bag with the material of an outer packaging bag to obtain a getter for a vacuum insulation panel.

[0044] In the embodiment of the present application, firstly, the desiccant and the first powder are mixed under the protection of the first protective gas, preferably for 4h to 5h, to obtain the powder. Wherein, the first protective gas is preferably nitrogen or an inert gas such as argon; the mixing is a technical means well known to those skilled in the art, and there is no special limitation in this application.

[0045] After the powder is obtained, the embodiment of the present application preferably uses an automatic packaging machine to ...

Embodiment 1

[0055] Under the protection of an inert gas, according to the mass ratio of 0.93:0.07, mix the calcium oxide and the first powder for 4 hours, and then use Dupont paper to package it into a bag under the protection of an inert gas to obtain a getter for vacuum insulation panels; wherein, the The first powder is CuO and MnO 2 The composite oxide, and the mass ratio of the two is 0.4:0.6.

[0056] According to the method described above, the getter performance test was carried out on the getter for vacuum insulation panels. The results show that its hydrogen absorption capacity reaches 6.1Pa·L / mg (the amount of gas that can be absorbed per milligram of powder), and its carbon monoxide and oxygen absorption capacities are 3.1Pa·L / mg and 2.4Pa·L / mg respectively.

[0057] The getter, the core material and the gas barrier layer are assembled to obtain a vacuum insulation panel; wherein, the core material is glass fiber, and the gas barrier layer is a composite aluminum foil bag.

...

Embodiment 2

[0060] Under the protection of an inert gas, according to the mass ratio of 0.9:0.1, mix the calcium oxide and the first powder for 4 hours, and then use DuPont paper to package it into a bag under the protection of an inert gas to obtain a getter for vacuum insulation panels; wherein, the The first powder is CuO, MnO 2 、Co 2 o 3 and Ag 2 A composite oxide of O, and the mass ratio of the four is 0.3:0.5:0.15:0.05.

[0061] According to the method described above, the getter performance test was carried out on the getter for vacuum insulation panels. The results show that its hydrogen absorption capacity reaches 6.5Pa·L / mg, and its carbon monoxide and oxygen absorption capacities are 3.2Pa·L / mg and 2.2Pa·L / mg respectively.

[0062] The getter was assembled according to the method of Example 1 to obtain a vacuum insulation panel. According to the method described above, the aging test was carried out on the vacuum insulation panel (recorded as L08, corresponding to B103B), ...

Abstract

The invention provides a getter for a vacuum insulation board. The getter comprises an external packaging bag and powder therein, wherein the powder comprises first powder which is an oxide mixture or a compound oxide, and the oxide mixture or the compound oxide is formed by at least two of manganese dioxide, manganese sesquioxide, manganous-manganic oxide, copper oxide, cerium dioxide, cobaltosic oxide, cobalt sesquioxide, aluminium sesquioxide, zinc dioxide and silver oxide; and a drier which comprises one or more of alkaline-earth metal oxides, soda lime, phosphorus pentoxide, chlorides and bromides. The getter is relatively good in gettering action, free of an activation process and safe and convenient to use and operate. The invention further provides the vacuum insulation board which comprises the getter. The vacuum insulation board not only has an excellent vacuum insulation effect, but also is safe and convenient to use and operate, and is low in cost.

Description

[0001] This application claims the priority of the Chinese patent application with the application number 201410496280.X and the title of the invention "Getter for Vacuum Insulation Panels and Vacuum Insulation Panels" submitted to the China Patent Office on September 25, 2014, the entire contents of which are approved References are incorporated in this application. technical field [0002] The application belongs to the technical field of vacuum heat insulation, and in particular relates to a getter for a vacuum heat insulation panel and a vacuum heat insulation panel. Background technique [0003] Vacuum insulation panel (VacuumInsulationPanel, referred to as VIP), is a kind of vacuum insulation material, which is composed of filling core material and vacuum protective layer. It mainly has three components: core insulation material (insulating material, which can be called core Material), gas barrier film (barrier, can be called gas barrier layer) and gas absorption mater...
