摘要：NOVELTY - A perlite-based normal temperature composite phase change material comprises inorganic porous material and organic solid-liquid phase change material which is dispersed in gap of inorganic porous material. USE - A perlite-based normal temperature composite phase change material for normal temperature phase transition energy storage. ADVANTAGE - Preparation method is simple and low cost, and leakage problem of organic solid-liquid phase change material is solved, improving thermal stability. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for preparation of perlite-based normal temperature composite phase change material which involves using ethyl alcohol or water as solvent, adding inorganic porous material in which solid-to-liquid ratio is 1:10-40, stirring at rotating speed of 100-400 rpm for 10-40 minutes at 40-100 degrees C, adding organic solid-liquid phase change material with melting temperature of 20-40 degrees C in which mass ratio mass ratio organic solid-liquid phase change material:inorganic porous material is 1:4, stirring at rotating speed of 400 rpm for 1-4 hours at 40-100 degrees C, and naturally cooling to 30-50 degrees C.
