<p><P>PROBLEM TO BE SOLVED: To provide a multilayer vacuum insulation material that discharges little gas, exhibits a high insulation effect and good working property at low cost. <P>SOLUTION: This multilayer vacuum insulation material 1a includes an aluminum sheet 13 on which hemispherical projections or the like are formed to reduce a contact area when laminated on another sheet 13, and a fluoroethylene resin film 14 baked and applied on one surface of the aluminum sheet 13, for preventing plastic deformation and serving as a heat insulation and reinforcement film for enhancing the heat resistance of a contact portion, and when the sheets 13 are laminated on one another, the position of a formed portion is shifted half of the pitch in the width and depth directions from the position of another formed portion of the adjacent member. Since the sheet 13 is configured with fluoroethylene resin film baked and applied thereon, the sheet 13 discharges little gas and the insulation effect is kept longer even in vacuum at low cost and with good working property. <P>COPYRIGHT: (C)2004,JPO</p> |
