Claims18
A composite useful in thermal energy storage comprising a matrix material having incorporated therein a phase change material, said phase change material being a crystalline, straight chain, alkyl hydrocarbon having 14 or more carbon atoms and a heat of fusion greater than 30 cal/g., said composite also comprising a flame retarding agent selected from the group consisting of halogenated hydrocarbons and halogenated phosphates.
A composite useful in thermal energy storage comprising a matrix material having incorporated therein a phase change material, said matrix material being plasterboard and said phase change material being a crystalline, straight chain, alkyl hydrocarbon having 14 or more carbon atoms and a heat of fusion greater than 30 cal/g., said plasterboard also comprising a flame retarding agent incorporated therein said flame retarding agent being selected from the group consisting of halogenated hydrocarbons and halogenated phosphates.
A composite useful in thermal energy storage comprising a matrix material having incorporated therein a phase change material and a flame retarding agent, said phase change material being a crystalline straight chain alkyl hydrocarbon having 14 or more carbon atoms and a heat of fusion greater than 30 cal/g and said flame retarding agent being a brominated hydrocarbon which is miscible in said phase change material.
