▎ 摘　　要

NOVELTY - Preparing coal gangue-based self-temperature regulating wall comprises mixing coal gangue powder, reinforcing agent, initiator, foaming agent and adhesive with water to obtain mixture, sequentially foaming and maintaining the mixture to obtain inorganic foamed wall, soaking the inorganic foamed wall in liquid phase change material to obtain phase-change temperature-regulating wall, and coating the surface of the phase-change temperature-regulating wall with polyvinyl chloride (PVC) composite material to obtain the coal gangue-based self-temperature-regulating wall, where the PVC composite material comprises PVC resin, graphene and carbon nanotubes, and the liquid phase change material comprises solid paraffin, liquid paraffin and phase change microcapsules. USE - The method is useful for preparing coal gangue-based self-temperature regulating wall. ADVANTAGE - The wall has excellent self-temperature-regulating effect. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for coal gangue-based self-temperature-regulating wall, comprising composite wall and PVC composite material layer wrapped on the surface of the composite wall, where the composite wall is inorganic foamed wall adsorbed with liquid phase change material.
