Preparation and Performance of Gypsum Matrix Phase Change Energy-Storage Material
Paraffin/expanded perlite composite phase change energy-storage material (PPCM) was prepared with expanded perlite as adsorption material and paraffin as phase change energy-storage material (PCM). The DSC and SEM results showed that the internal micropores of expanded perlite were filled with paraffin; the phase change temperature of PPCM was basically similar with that of paraffin and the latent heat of PPCM was corresponded with that of paraffin based on mass ratio among PPCM. PPCM was incorporated into gypsum to prepare gypsum matrix phase change energy-storage material (GPCM), and its mechanical properties, water absorption and temperature control effect were determined. The results showed that with the increase of PPCM’s content, the 2h compressive strength, flexure Strength and water absorption of GPCM continuously declined and its temperature control effect significantly enhanced.
