PURPOSE:A stable, inexpensive and notoxic thermal energy storage material, obtained by adding a phenolic compound, etc. to a molded article of an intermolecularly crosslinked crystalline polyolefin (copolymer), and coating the surface thereof with heat-resistant fine powder without corroding a metallic material, and utilizing the latent heat of melting. CONSTITUTION:A thermal energy storage material obtained by molding a particularly highly crystalline polyolefin, e.g. crystalline polyethylene (PE) or polypropylene (PP), or a copolymer thereof into a given shape, crosslinking the resultant molded article intermolecularly by the radiation or water crosslinking method, etc., adding a phenolic compound or amine, e.g. cresol or phenylenediamine, thereto, and coating the surface thereof with heat-resistant fine powder, e.g. aluminum oxide, silica gel, magnesium carbonate, zirconia, graphite or silicon carbide. |
