Abstract

A vacuum insulation material including: a core material; and a gas adsorbing agent, wherein the core material and the gas absorbing agent are interposed between a pair of gas barrier materials, wherein at least one of the pair of gas barrier materials includes a quasicrystal metal layer including a quasicrystal metal. The vacuum insulation material may reduce the heat bridge while maintaining high gas barrier properties.

First claim

What is claimed is:

1 . A vacuum insulation material comprising:
a core material; and a gas adsorbing agent, wherein the core material and the gas absorbing agent are interposed between a pair of gas barrier materials, wherein at least one of the pair of gas barrier materials comprises a quasicrystal metal layer comprising a quasicrystal metal.

2 . The vacuum insulation material of claim 1 , wherein the quasicrystal metal layer has an intrinsic thermal conductivity of less than or equal to about 10 watts per meter-Kelvin.

3 . The vacuum insulation material of claim 1 ,
wherein the quasicrystal metal is an alloy of the formula Al-TM-M or an alloy of the formula Al-TM, wherein TM is at least one of a transition metal and M is at least one element selected from a semi-metal and a semiconductor, or wherein the quasicrystal metal is an alloy of the formula RE-Mg—Zn, wherein RE is at least one element selected from a rare earth element or gallium.

4 . The vacuum insulation material of claim 3 ,
wherein the quasicrystal metal is an alloy of the formula
Al 100-a-b-x TM a M b ,
wherein TM is at least one transition metal selected from vanadium, chromium, manganese, iron, cobalt, nickel, copper, ruthenium, palladium, silver, rhenium, osmium, and gold,
wherein M is at least one element selected from lithium, magnesium, silicon, and germanium,
wherein a is 10≦a≦20,
wherein b is 8≦b≦35, and
wherein x is 0≦x≦0.05,
wherein the quasicrystal metal is an alloy of the formula Al 100-c-y TM c ,
wherein TM is at least one transition metal selected from vanadium, chromium, manganese, iron, cobalt, nickel, copper, ruthenium, palladium, silver, rhenium, osmium, and gold,
wherein c is 16≦c≦40,
wherein y is 0≦y≦0.05), or
wherein the quasicrystal metal is an alloy of the formula
RE 100-d-e-z Mg d Zn e ,
wherein RE is at least one rare earth element selected from yttrium, europium, gadolinium, terbium, dysprosium, and holmium,
wherein d is 18≦d≦36,
wherein e is 21≦e≦70, and
wherein z indicates a composition of impurities and is 0≦z≦0.05.

5 . The vacuum insulation material of claim 4 , wherein the quasicrystal metal is Al 62.5 Cu 25 Fe 12.5 , Al 70 Pd 20 Mn 10 , or Y 8 Mg 36 Zn 56 .

6 . The vacuum insulation material of claim 1 , wherein the quasicrystal metal layer is formed by rolling or sputtering.

7 . The vacuum insulation material of claim 1 , wherein at least one of the pair of gas barrier materials comprises a laminate of the quasicrystal metal and a polymeric material.

8 . The vacuum insulation material of claim 1 , wherein the quasicrystal metal layer comprises the quasicrystal metal.
