HEAT INSULATION PANEL AND HEAT INSULATION STRUCTURE

Title:

HEAT INSULATION PANEL AND HEAT INSULATION STRUCTURE

Document Type and Number:

Japanese Patent JP2017172724

Kind Code:

A

Abstract:

PROBLEM TO BE SOLVED: To provide a heat insulation panel and a heat insulation structure using the heat insulation panel in which it is possible to restrict occurrence of crack at a heat insulation material such as urethane foam or the like that is a main body of the heat insulation panel even if the heat insulation panel is used as a low temperature tank and it is also possible to keep a desired heat insulation effect.SOLUTION: This invention relates to a heat insulation panel 10 having a vacuum heat insulation material 11 of which core material 111 is reduced in its pressure and sealed with a covering material 112 of gas-barrier characteristic; and having a heat insulation material 12 storing the vacuum heat insulation material 11 in it to form an integral state with a coefficient of linear expansion of JIS K 7197 of 1×10to 90×10/°C, and a stress relaxation material 13 is arranged between the vacuum heat insulation material 11 and the heat insulation material 12.SELECTED DRAWING: Figure 1B
