Vacuum heat insulating panel and method for manufacturing same

A method for manufacturing a vacuum heat-insulating panel, comprising the steps of:

• (a) manufacturing a core layer, comprising pouring molten glass at a high temperature of 1100° C. to 1300° C. into a centrifugal head spinning at a high speed, wherein the spinning speed of the centrifugal head is 2000 rpm to 2500 rpm, flinging out fiber filaments, and forming a uniform laminated structure by using a bottom suction apparatus, wherein the diameter of the fiber filament is 1 μm to 3 μm;
• (b) wrapping with an outer wrapping layer, comprising placing a calcium oxide getter inside the core layer, wrapping the core layer with a composite wrapping layer of which one surface or two surfaces do not comprise aluminum foils, and performing heat sealing on the outer wrapping layer;
• and
• (c) vacuumizing the core layer sealed by the outer wrapping layer in step (b), and forming a vacuum heat-insulating panel.
