Resin member and sheet using same, and heat storage material and heat control sheet using same
In one aspect, the present invention provides a resin member comprising a copolymer of ethylene and an olefin having 3 or more carbon atoms, and a straight-chain saturated hydrocarbon compound.
1. A resin member comprising:
a copolymer of ethylene and an olefin having 8 carbon atoms;
a straight-chain saturated hydrocarbon compound, wherein a melting point of the straight-chain saturated hydrocarbon compound is less than 50° C.; and
a polymer having a melting point of 100° C. or more.
2. A sheet comprising:
a metal layer; and
a resin layer formed on the metal layer and composed of the resin member according to claim 1 .
3. A heat storage material comprising:
a copolymer of ethylene and an olefin having 8 carbon atoms;
a straight-chain saturated hydrocarbon compound, wherein a melting point of the straight-chain saturated hydrocarbon compound is less than 50° C.; and
a polymer having a melting point of 100° C. or more.
4. A heat control sheet comprising:
a metal layer; and
a heat storage layer formed on the metal layer and composed of the heat storage material according to claim 3 .
5. The resin member according to claim 1 , wherein the straight-chain saturated hydrocarbon compound comprises n-tetradecane, n-pentadecane, n-hexadecane, n-heptadecane, n-octadecane, n-nanodecane, n-eicosane, n-heneicosane, n-docosane, or n-tricosane.
6. The resin member according to claim 1 , wherein the polymer having a melting point of 100° C. or more comprises one or more of polyethylene (ethylene homopolymer), polypropylene (propylene homopolymer), a modified polymer of polyethylene or polypropylene that includes monomer units other than ethylene or propylene, or a copolymer of ethylene or propylene and another monomer.
7. The heat storage material according to claim 3 , wherein the straight-chain saturated hydrocarbon compound comprises n-tetradecane, n-pentadecane, n-hexadecane, n-heptadecane, n-octadecane, n-nanodecane, n-eicosane, n-heneicosane, n-docosane, or n-tricosane.
8. The heat storage material according to claim 3 , wherein the polymer having a melting point of 100° C. or more comprises one or more of polyethylene (ethylene homopolymer), polypropylene (propylene homopolymer), a modified polymer of polyethylene or polypropylene that includes monomer units other than ethylene or propylene, or a copolymer of ethylene or propylene and another monomer.
