Title:
VACUUM HEAT INSULATING PANEL AND REFRIGERATOR USING THE SAME
Document Type and Number:
Japanese Patent JP2007056973
Kind Code:
A
Abstract:
To provide an ecological vacuum heat insulating material which compatibly secures a bending property and shape retaining property and improving heat conductivity.
The vacuum heat insulating material 30 comprises a shell material 31 having gas barrier performance and a core material 32 vacuumed and sealed therein. The core material 32 is formed of a fiber polymer which does not contain a binder having an average fiber diameter of 2 μm or larger. In a space of the shell material 31, a deformation retaining member 33 is arranged which is deformable and which can retain the shape of the core material after deformed. The deformation retaining member 33 is formed of a biodegradable material into a fibriform mat.
