The invention discloses a new vacuum insulating material and preparing method, which is characterized by the following: the periphery near core material side contains non-deposition part, bending part, overlapping part, corner non-deposition part, which provides small hole on the overlapped film to avoid cracking and air permeating; The core material 2 is contained in the bag bulk F of choke filmwith heat fusing coat, which forms vacuum insulating material 1; the entire bulk or non-deposition part is heat under normal pressure, which fuses the non-deposition part of bag bulk F. |
