Title:
HEAT-INSULATING SHEET AND METHOD FOR MANUFACTURING SAME
Document Type and Number:
WIPO Patent Application WO/2020/183773
Kind Code:
A1
Abstract:
This heat-insulating sheet comprises: a fiber sheet having a space in the interior thereof; and a silica xerogel supported in the space. The heat-insulating sheet has a high-compression region and a low-compression region. The compression ratio of the high-compression region is 30% to 50% with respect to a pressure of 0.25 MPa applied to the high-compression region. The compression ratio of the low-compression region is 1% to 5% with respect to a pressure of 0.25 MPa applied to the low-compression region. This heat-insulating sheet enables an improvement in the overall heat-insulating effect.
