Core for Heat Insulating Material Method for Manufacturing the Same and Slim Type Heat Insulating Material Using the Same

摘要

The present invention relates to a nano-web having a three-dimensional structure obtained by electrospinning a polymer material having a low thermal conductivity by stacking a plurality of layers of nano-webs as a core material and having a plurality of micropores capable of trapping air, A core for a heat insulator, a manufacturing method thereof, and a slim heat insulator using the same. The heat insulating material core of the present invention is characterized by comprising a porous nano-web having a three-dimensional micro-pore structure, which is made of a polymer having a low thermal conductivity and is integrated by nanofibers having a diameter of less than 1 μm.
