The vacuum insulation panel mainly comprises a core material, an adsorbent and a barrier protection bag, and the manufacturing method comprises the following steps: putting the core material and the adsorbent into a barrier protective bag, vacuumizing and sealing. The heat preservation principle is as follows: the core material has low heat conduction characteristic; vacuumizing to reduce air convection; the multi-layer composite barrier film used for the barrier protection bag can effectively prevent the permeation of water and gas outside the vacuum insulation panel. The core material adopted by the vacuum insulation panel comprises: the glass fiber cotton and the SiO2 powder are compressed and molded, wherein the glass fiber cotton is made by a papermaking process, is relatively fluffy and has high vacuum compression rate, so that after vacuum compression, once vacuum failure occurs, a core material can be immediately swelled, a wall body is cracked if the core material is light, a wall surface falls off if the core material is heavy, and the potential safety hazard is relatively large; the core material formed by compressing SiO2 powder is fragile, low in strength and large in surface dust, cannot be thermally combined with the blocking protective belt, and once the vacuum fails, the core material can swell or absorb moisture and crack immediately, so that the potential safety hazard is large.
