If the air tightness is poor, it is easy to cause the exchange of gas inside and outside the storage library, cause temperature fluctuation, dew and even material deterioration, and seriously affect the storage effect.

[0003] At present, these storage libraries usually use concrete or steel plate as wall or enclosure structure, and the heat preservation core material is usually traditional heat preservation material such as polyurethane (PU), polystyrene (EPS) or rock wool. However, these traditional heat preservation materials generally have the problem of relatively high thermal conductivity, usually above 0.020 W / (m·K), which leads to limited heat preservation and insulation performance of the storage library, and it is difficult to meet the requirement of near zero energy consumption. In order to achieve the required heat preservation effect, it is often necessary to increase the thickness of the heat preservation layer, which not only increases the material cost and structural self weight, but also occupies the valuable storage space. In addition, when the traditional heat preservation plate is installed on the wall or steel plate of the storage library, a thermal bridge is easily formed at the joint, which leads to the loss of cold or heat, affects the overall heat preservation effect and air tightness.
