Title:
FOAMED RESIN INSULATION MATERIAL, AND METHOD FOR MANUFACTURING SAME
Document Type and Number:
WIPO Patent Application WO/2024/071394
Kind Code:
A1
Abstract:
Provided are: a foamed resin insulation material that can reduce the difference in coefficient of linear expansion between a metal and a foamed resin insulation material, reduce thermal stress generated in the foamed resin insulation material as much as possible, and prevent the occurrence of cracks; and a method for manufacturing the same. The foamed resin insulation material comprises a foamed resin molded body molded by foaming an unfoamed resin material in which a negative thermal expansion material that contracts in volume as the temperature rises and expands as the temperature falls is mixed. A fiber sheet composed of intersecting warp threads and weft threads is integrated with the inner and outer surfaces of the foamed resin molded body.
