Background

With the proposals of building energy-saving system concepts such as Passive houses (Passive houses), zero emission buildings (zero emission buildings) and the like, the Passive houses and the zero emission buildings show that the Passive houses and the zero emission buildings actively deal with higher building energy consumption at home and abroad, and the heat insulation and the heat preservation of the buildings play an important role. As part of building materials, the importance of thermal insulation is steadily increasing. The light heat-insulating material has limited thermal capacity and low heat storage capacity, and cannot achieve the purpose of efficient heat storage and heat insulation, so that the traditional heat-insulating material with low heat conductivity coefficient cannot meet the actual use requirement.

The phase change energy storage honeycomb composite board mainly made of honeycomb materials is manufactured by adding phase change materials into traditional building honeycomb materials, and the phase change energy storage honeycomb composite board is a light building material with high heat capacity and has high latent heat storage capacity. The material can improve the energy-saving heat-insulating capacity of buildings, automatically adjust the indoor temperature, reduce the fluctuation of the indoor temperature and improve the comfort level.

However, the phase-change material has high self thermal conductivity, and when the phase-change material is added into the honeycomb panel, the overall thermal conductivity of the honeycomb panel is increased, and even if the traditional foam material is matched as a phase-change material carrier, the phase-change material with high thermal conductivity can form a thermal conductive network, so that the thermal insulation performance of the honeycomb panel is reduced. In addition, in the phase change process, the phase change material can flow out of the honeycomb plate or the porous medium due to the change of the state of the phase change material, so that the phase change material is not uniformly distributed, and the performance of the phase change energy storage honeycomb composite plate is adversely affected.
