Insulating heat insulating plate and heat insulating box, wall plate or floor plate using the heat insulating plate

摘要

To provide a heat insulating heat insulating plate having a simple structure, excellent impact resistance and corrosion resistance, hardly damaged, and resistant to fire, and a heat insulating box, a wall plate or a floor plate using the heat insulating plate. A heat insulating heat insulating plate includes a vacuum heat insulating panel and at least one side surface foam covering the vacuum heat insulating panel, and an aluminum film is provided on the outer side of the foam or foamed. A metal powder paint is applied to the outside of the body 12. A nonwoven fabric or glass fiber layer 14 is provided between the foam 12 and the aluminum film 13, and after coating the nonwoven fabric or glass fiber cloth on the foam 12, a metal powder paint (aluminum powder paint is preferred) is applied. To do. The installation of the glass fiber layer 14 can further enhance the fireproof performance. [Selection] Figure 1
