Document Type and Number:
WIPO Patent Application WO/2023/145907
Kind Code:
A1
Abstract:
Provided is a thermally expandable refractory material containing: at least one matrix component selected from the group consisting of a rubber and a resin; thermally expandable graphite; and a flexibility imparting agent, wherein both the rubber and the resin are solid at 23°C. When the thermally expandable refractory material is cut into a size of 25 mm × 25 mm × 2 mm and placed in a space of 6 mm in the thickness direction, and then heated at 400°C for 15 minutes in each space, the closed expansion ratio of the thermally expandable refractory material is at least 4.0 as obtained by dividing the area of the thermally expandable refractory material seen in the thickness direction by the area prior to heating.
