Polyolefin thermal energy storage material having heat-resistant resin film

Abstract

Abstract PURPOSE:A stable, inexpensive and nontoxic thermal energy storage material, obtained by adding a phenolic compound, etc. to a molded article of an intermolecularly crosslinked polyolefin (copolymer), and coating the surface of the article with a heat-resistant resin film 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 of the article with a heat-resistant resin film, e.g. fluororesin, silicone resin, PVC, PP or polyimide.
