Abstract
Official abstract text for this publication.
The present invention is a resin composition including: a resin component; zinc oxide; and an acetic acid remover, wherein the resin component includes an ethylene-vinylacetate copolymer and a content of the ethylene-vinylacetate copolymer in the resin component is greater than or equal to 10% by mass, wherein the acetic acid remover is an acid acceptor, a nitrogen-containing aromatic heterocyclic compound having a mercapto group, or a combination thereof, and wherein a mass ratio of the zinc oxide to the ethylene-vinylacetate copolymer is greater than or equal to 0.06 and less than or equal to 0.20.
First claim
Opening claim text (preview).
The invention claimed is: 1. A resin composition comprising: a resin component; zinc oxide; and an acetic acid remover, wherein the resin component includes an ethylene-vinylacetate copolymer and a content of the ethylene-vinylacetate copolymer in the resin component is greater than or equal to 10% by mass, wherein the resin component includes high-density polyethylene and a content of the high-density polyethylene is greater than or equal to 30 parts by mass and less than or equal to 75 parts by mass with respect to 100 parts by mass of the resin component, wherein the acetic acid remover is an acid acceptor, a nitrogen-containing aromatic heterocyclic compound having a mercapto group, or a combination thereof, wherein a mass ratio of the zinc oxide to the ethylene-vinylacetate copolymer is greater than or equal to 0.06 and less than or equal to 0.20, and wherein a mass ratio of the acetic acid remover to the zinc oxide is greater than or equal to 0.1 and less than or equal to 10. 2. The resin composition according to claim 1 , wherein the acid acceptor is silica, hydrotalcite, magnesium oxide, magnesium hydroxide, aluminum hydroxide, or a combination thereof. 3. The resin composition according to claim 1 , wherein the nitrogen-containing aromatic heterocyclic compound having the mercapto group is a 2-mercaptoimidazole compound or a 2-mercaptothiazole compound. 4. An electrical cable comprising a conductor; and a resin coating layer around the conductor, wherein the resin coating layer is formed of the resin composition according to claim 1 . 5. An electrical cable comprising: a conductor; and a resin coating layer around the conductor, wherein the resin coating layer is formed of an electron-beam crosslinked body of the resin composition according to claim 1 .
