AB  - In this study, paraffin was selected as the phase change material (PCM) and 
      high-density polyethylene (HDPE) as the supporting material to prepare a 
      flame-retardant PCM system. The system consisted of paraffin, HDPE, expanded 
      graphite (EG), magnesium hydroxide (MH) and aluminum hydroxide (ATH). The thermal 
      stability and flame retardancy were studied by thermo-gravimetric analysis (TGA), 
      scanning electron microscopy (SEM) and cone calorimeter test (CONE). The SEM 
      proved that the addition of MH and ATH can produce an oxide film on the surface 
      of the composite material and form a "physical barrier" with the char layer, 
      generated by the expansion of EG, preventing the transfer of heat and oxygen. The 
      TGA test showed that, compared with other flame-retardant systems, the materials 
      with added MH and ATH have a higher thermal stability and carbonization ability, 
      and the amount of char residue has increased from 17.6% to 32.9%, which reduces 
      the fire risk of the material. The flame retardant effect is obvious. In 
      addition, the addition of MH and ATH has no significant effect on the phase 
      transition temperature and latent heat value of PCMs. The CONE data further 
      confirmed that MH and ATH can work with EG to prevent heat release, reduce the 
      total heat release rate (THR) value and effectively suppress the generation of 
      smoke, CO and CO(2). The peak heat release rate (PHRR) value also decreased, from 
      1570.2 kW/m(2) to 655.9 kW/m(2).
