VACUUM HEAT INSULATING MATERIAL AND REFRIGERATOR USING THE SAME

摘要

PROBLEM TO BE SOLVED: To maintain heat insulating performance over a long period of time by suppressing an increase in the intrusion of gas and moisture from an outer material surface occurring in a structure not using metal foil for reducing an effect of a heat bridge in a vacuum heat insulating material used for a refrigerator.

SOLUTION: The vacuum heat insulating material used for the refrigerator comprises: a surface layer of a jacketing material having a gas barrier film of an aluminum deposition layer with a resin material having a moisture proof property as a base material; a gas barrier layer having a gas barrier film of an aluminum deposition layer with a resin material with a high gas barrier property as a base material; a thermal deposition layer formed of a resin material having a moisture proof property; and an inner wrapper covering a core material composed of a resin material having a moisture proof property.
