Abstract: In this study, we prepared paraffin based mixed SSPCM (PBMS) and gypsum boards. The prepared PBMS was added to gypsum powder as a fine aggregate. In the experiment, we used n-hexadecane and n-octadecane as the PCM, which have 254.7J/g and 247.6J/g of latent heat capacity, and melting points of 20.84°C and 30.4°C, respectively. The PBMS was prepared by an impregnation method in a vacuum, following the manufacturing process. The physical and thermal properties of the PBMS gypsum board were analyzed by Fourier transform infrared spectrometry, differential scanning calorimetry, enthalpy analysis and thermogravimetric analysis. From the FTIR analysis, PBMS could be maintained in the structure of the gypsum board due to its physical rather than chemical bonding. From the specific heat and enthalpy analysis, the PBMS has high enthalpy and thermal inertia property. In addition, we confirmed that the gypsum board with PBMS has high latent heat capacity and high thermal efficiency.
