Vacuum insulation material, adiabatic structure using the same, and household appliance, housing wall and transportation equipment using the same

摘要

The vacuum heat insulating material (10) includes a bag-shaped outer cover material (12) having a gas barrier property, a core material (11) sealed inside the outer cover material (12) in a vacuum-sealed state, and a core material ( Along with 11), a gas adsorbent (13) sealed inside the outer cover material (12) is provided. The outer cover material (12) contains a gas barrier layer (122) containing at least a layered clay mineral as a filler. The gas adsorbent (13) contains at least a synthetic zeolite having a pore size of 5 Å or more and less than 8 Å.
