Embodiment approach 1
[0051] use figure 1 and 2 Embodiment 1 of the present invention will be described. figure 1 It is a cross-sectional view of the vacuum thermal insulation material according to Embodiment 1 of the present invention; figure 2 It is a sectional view of a heat insulating case using a heat insulating material according to Embodiment 1 of the present invention.
[0052] refer to figure 1 The vacuum heat insulating material 1 comprises a powder mixture obtained by stirring pulverized polyurethane foam powder having an average particle diameter of 150 μm and synthetic silica powder with a stirring mill at high speed (3600 rpm). The grinding powder of the polyurethane foam is obtained by grinding the polyurethane foam on a 150 μm abrasive cloth.
[0053]The prepared powder mixture is filled into a gas-permeable nonwoven fabric to form a core material 2 . The core 2 is placed in an outer part 3 consisting of a metal-plastic film laminate. The gas in the inner space surrounded by ...
Embodiment approach 2
[0068] Described below are the vacuum heat insulating material 1 and the heat insulating box 4 using the vacuum heat insulating material in Embodiment 2 of the present invention. The structure and figure 1 and 2 The embodiment 1 described in is the same and will not be specifically described here.
[0069] The vacuum heat in Embodiment 2 can be prepared by filling the mixture of ground polyurethane foam and synthetic silica powder into the outer layer member 3 made of a metal-plastic film laminate, and then sealing the outer layer member 3 under reduced pressure. Insulation Materials.
