Title:
HEAT INSULATING SHEET, HEAT INSULATING MATERIAL, AND METHOD FOR MANUFACTURING HEAT INSULATING SHEET
Document Type and Number:
WIPO Patent Application WO/2019/181186
Kind Code:
A1
Abstract:
Provided are a heat insulating sheet, a heat insulating material, and a method for manufacturing a heat insulating sheet, which reflect radiant heat and exhibit an excellent heat insulation performance in a vacuum environment or a low atmospheric pressure environment. The heat insulating sheet is provided with a resin film having a metal layer, a non-woven fabric including a resin fiber, wherein the resin film and the non-woven fabric can be joined by penetration holes penetrating through the resin film and the non-woven fabric. The ratio (La/Lb) of an average distance (La) between penetration holes in the resin film and an average distance (Lb) between a plurality of penetration holes in the non-woven fabric can be 1.0010-1.10.
