Title:
発泡断熱材の製造方法および発泡断熱材
Document Type and Number:
Japanese Patent JP6677426
Kind Code:
B2
Abstract:
Provided is a foamed heat-insulating material which encapsulates therein a low-heat conductivity gas and which yields high heat insulating performance. High-melting point beads that have been foamed up to a prescribed expansion ratio with a gas of low thermal conductivity by using a resin that does not soften at the beads-foaming temperature and that has a low gas transmission rate are mixed with low-temperature foam beads to be foamed within a forming die, and the resultant mixture is filled in a beads forming die cavity and foamed by heating.
