Title:
VACUUM HEAT INSULATION MATERIAL
Document Type and Number:
Japanese Patent JP2019184020
Kind Code:
A
Abstract:
To provide a vacuum heat insulation material making it possible to carry out molding in a three-dimensional shape having sufficient heat insulation performance even if it is a thin type.SOLUTION: A vacuum heat insulation material 2 includes a core member 30 and an outer packaging 40 obtained by subjecting the core member 30 to decompression sealing. The core member includes an inner layer 10 and an outer layer 20. The inner layer is composed of an inorganic fiber sheet 4 or a laminate sheet in which the inorganic fiber sheet 4 and resin fiber sheets 6a and 6b are alternately disposed. The outer layer is composed of the resin fiber sheets 6 and 6b disposed so as to be in contact with an upper surface 10a and a lower surface 10b of the inner layer 10.SELECTED DRAWING: Figure 1
