Abstract
An electrical cable comprising a core having at least one inner conductor surrounded by a dielectric material, a metallic sheath surrounding said core, and an adhesive bonding said metallic sheath to said core, said adhesive comprising a water dispersible copolymer of ethylene and an ethylenically unsaturated carboxylic acid forming a thin film between said metallic sheath and said core.
Claims9
An electrical cable comprising a core having at least one inner conductor surrounded by a dielectric material, a metallic sheath surrounding said core, and an adhesive bonding said metallic sheath to said core, said adhesive comprising a dried water dispersible copolymer of ethylene and an ethylenically unsaturated carboxylic acid forming a thin film between said metallic sheath and said core, and wherein said copolymer is rendered water dispersible by partial neutralization of the ethylenically unsaturated carboxylic acid by reaction with a monovalent metal hydroxide, and wherein a portion of said carboxylic acid is unreacted to provide carboxyl groups present in the adhesive for effecting bonding between said metallic outer conductor and said core.
An electrical cable comprising a core having at least one inner conductor and a foam dielectric surrounding said at least one inner conductor, a metallic sheath surrounding said core, and an adhesive bonding said metallic sheath to said core, said adhesive comprising a dried water dispersible random copolymer of ethylene and acrylic acid containing at least 15 percent by weight acrylic acid, with a portion of the acrylic acid being neutralized by reaction with a monovalent metal hydroxide to render the copolymer water dispersible, and with at least 2 percent of the acrylic acid being unreacted to provide carboxyl groups present in the adhesive for effecting bonding between said metallic sheath and said core.
An electrical cable comprising a core having at least one inner conductor and a foam dielectric surrounding said at least one inner conductor, a metallic sheath surrounding said core, and an adhesive bonding said metallic sheath to said core, said adhesive comprising a dried water dispersible random copolymer obtained from the copolymerization of ethylene and acrylic acid, with a portion of the acrylic acid being neutralized by reaction with a monovalent metal hydroxide to render the copolymer water dispersible, and wherein a portion of said carboxylic acid is unreacted to provide carboxyl groups present in the adhesive for effecting bonding between said metallic outer conductor and said core.
