COATING LAYER FOR HEAT INSULATION, LAMINATE FOR HEAT INSULATION, COATING MATERIAL FOR HEAT INSULATION AND PROCESS FOR PRODUCTION OF THE COATING MATERIAL

摘要

A coating layer for a thermal insulator, in a laminated body for a thermal insulator, the laminated body including a carbonized-molded body and the coating layer for a thermal insulator which is layered on at least one surface of the carbonized-molded body,
wherein the bulk density of the carbonized-molded body is 0.08 g/cm 3 to 0.8 g/cm 3 and
the gas permeability ratio of the coating layer for a thermal insulator is 8.0 NL/hr·cm 2 ·mmH 2 O or less.
