摘要:
Disclosed are a vacuum insulation panel, a method for manufacturing the same and an insulation box having the same. By cutting the core material correspondingly to shape and thickness of the absorbent without cut of the core material and pressing the absorbent securing part to form the groove for placing the absorbent therein, the vacuum insulation panel prevents partial deterioration of heat transmission caused by the cutoff of the core material or deterioration of the smoothness caused by placing the absorbent above the core material or between the core materials. Particularly, it is possible to prevent the phenomenon that the periphery is pressed together, which is shown in a conventional press process, to thereby improve the smoothness by cutting the core material in shape and depth corresponding to the shape and thickness of the absorbent prior to the press of the absorbent securing part. Therefore, it is possible to provide an energy saving insulation box by reducing generation of wrinkle or poor sealing of the surface material of the vacuum insulation panel to thereby increase insulation efficiency of the vacuum insulation panel for a long time.

摘要:
The vacuum thermal insulation material of the present invention comprises: a core material part which is hermetically sealed under reduced pressure; a getter part which is provided on one side in the middle of the core part; and an outer skin material part which surrounds the core material part and is hermetically sealed. In the getter part, a getter material, comprising a mixture of a hygroscopic material and a gas-adsorbing material, is packed in the form of a nonwoven fabric. In the vacuum thermal insulation material of the present invention, the hygroscopic material is any one of calcium oxide, calcium chloride, zeolite, silica gel, alumina and activated carbon, while the gas-adsorbing material is an oxygen-adsorbing material comprising a Fe based compound; and the hygroscopic material and the gas-adsorbing material are mixed in a ratio of between 20:1 and 200:1.
