<p><P>PROBLEM TO BE SOLVED: To provide a vacuum heat insulating material capable of maintaining heat insulating performance over a long time even in a high-temperature range of 150°C or more by changing an adhesive between coating material films. <P>SOLUTION: As the adhesive between the coating material films, a polyester group, an epoxy group and a silicone group adhesives having 160°C or more of heat resistance are used. Even in the high-temperature atmosphere at about 150°C, the generation of peeling and de-lamination between the coating material films can be prevented by using these adhesives, and heat insulating performance can be maintained over a long time. <P>COPYRIGHT: (C)2005,JPO&NCIPI</p> |
