Resin member and sheet using same, method for producing resin member, and heat storage material and heat control sheet using same
In one aspect, the present invention is a resin member comprising a copolymer of ethylene and an olefin having 3 or more carbon atoms, a straight-chain saturated hydrocarbon compound, and a gelling agent.
1. A resin member comprising:
a copolymer of ethylene and an olefin having 3 or more carbon atoms;
a straight-chain saturated hydrocarbon compound; and
at least one selected from the group consisting of a carboxylic acid and a carboxylic acid metal salt, wherein the metal constituting the carboxylic acid metal salt is aluminum,
wherein the resin member is in the form of a sheet, and
wherein a content of the copolymer of ethylene and an olefin having 3 or more carbon atoms is 5% by mass or more and 50% by mass or less based on the total amount of the resin member, a content of the straight-chain saturated hydrocarbon compound is 40% by mass or more and 90% by mass or less based on the total amount of the resin member, and a content of the at least one selected from the group consisting of a carboxylic acid and a carboxylic acid metal salt is 3% by mass or more and 10% by mass or less based on the total amount of the resin member.
2. The resin member according to claim 1 , wherein a number of carbon atoms of the olefin is 3 to 8.
3. The resin member according to claim 1 , wherein a melting point of the straight-chain saturated hydrocarbon compound is less than 50° C., and the number of carbon atoms of the olefin is 8.
4. The resin member according to claim 1 , wherein a melting point of the straight-chain saturated hydrocarbon compound is 50° C. or more, and the resin member further comprises at least one selected from the group consisting of a polyethylene and a polypropylene.
5. 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 .
6. The resin member according to claim 1 , wherein a content of the copolymer of ethylene and an olefin having 3 or more carbon atoms is 10% by mass or more and 40% by mass or less based on the total amount of the resin member.
7. The resin member according to claim 1 , wherein a content of the copolymer of ethylene and an olefin having 3 or more carbon atoms is 15% by mass or more and 30% by mass or less based on the total amount of the resin member.
8. The resin member according to claim 1 , wherein the straight-chain saturated hydrocarbon compound has a melting point within a range of 0 to 100° C.
9. The resin member according to claim 1 , wherein a content of the straight-chain saturated hydrocarbon compound is 45% by mass or more and 80% by mass or less based on the total amount of the resin member.
10. The resin member according to claim 1 , wherein a content of the straight-chain saturated hydrocarbon compound is 50% by mass or more and 70% by mass or less based on the total amount of the resin member.
11. The resin member according to claim 1 , further comprising a polymer having a melting point of 100° C. or more.
