Abstract
Abstract Metal to rubber adhesion is improved by metal substrates having a coating thereon such as brass, copper, and the like. The coating is applied by an ion beam sputter deposition or, in the alternative, such a coating is partially removed through ion beam etching. The present invention is particularly useful in tire cord construction, metal reinforced belts and hoses, and the like, since articles made therefrom have superior and unexpected moisture aged rubber-to-metal adhesion properties.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
73 words
A process for preparing a metal surface for adhesion to rubber, comprising the steps of: applying a metal to a metal substrate utilizing an ion beam sputter deposition process until a coating of from about 5 to about 4,000 angstrom units is obtained; the coating metal being selected from the group consisting of steel, zinc, copper, iron, nickel, aluminum, cobalt, and alloys thereof including brass, and applying rubber to said coated metal surface.
Claim 2
Dependent Claim
73 words
A process for preparing a metal surface for adhesion to rubber, comprising the steps of: applying a metal to a metal substrate utilizing an ion beam sputter deposition process until a coating of from about 5 to about 4,000 angstrom units is obtained; the coating metal being selected from the group consisting of steel, zinc, copper, iron, nickel, aluminum, cobalt, and alloys thereof including brass, and applying rubber to said coated metal surface.
Claim 3
Dependent Claim
22 words
A process according to claim 1, wherein the thickness of said metal coating is from about 500 to about 1,000 angstrom units.
Claim 4
Dependent Claim
56 words
A process according to claim 2, wherein said rubber is selected from the group consisting of dienes having from 4 to 12 carbon atoms, and interpolymers thereof, interpolymers made from dienes having from 4 to 12 carbon atoms and vinyl substituted aromatics having from 8 to 12 carbon atoms, nitrile rubber, EPDM, polychloroprene, and combinations thereof.
Claim 5
Dependent Claim
44 words
A process according to claim 3, wherein said metal coated surface is a tire cord, or a tire bead; and wherein said rubber is selected from the group consisting of natural or synthetic cis-1,4-polyisoprene, polybutadiene, and styrene-butadiene rubber; and wherein said coating is copper.
Claim 6
Dependent Claim
76 words
A process for preparing a metal coated surface for adhesion to rubber, comprising the steps of: sputter etching with an ion beam the metal coated surface to remove coating material; so that a coating of from about 5 to about 4,000 angstrom units remains, wherein said coating material is selected from the group consisting of steel, zinc, copper, brass, iron, nickel, aluminum, cobalt, and alloys thereof including brass, and applying a rubber to said etched surface.
Claim 7
Dependent Claim
76 words
A process for preparing a metal coated surface for adhesion to rubber, comprising the steps of: sputter etching with an ion beam the metal coated surface to remove coating material; so that a coating of from about 5 to about 4,000 angstrom units remains, wherein said coating material is selected from the group consisting of steel, zinc, copper, brass, iron, nickel, aluminum, cobalt, and alloys thereof including brass, and applying a rubber to said etched surface.
Claim 8
Dependent Claim
19 words
A process according to claim 5, wherein the thickness of said coating layer is 500 to 1,000 angstrom units.
Claim 9
Dependent Claim
56 words
A process according to claim 6, wherein said rubber is selected from the group consisting of dienes having from 4 to 12 carbon atoms, and interpolymers thereof, interpolymers made from dienes having from 4 to 12 carbon atoms and vinyl substituted aromatics having from 8 to 12 carbon atoms, nitrile rubber, polychloroprene, EPDM, and combinations thereof.
Claim 10
Dependent Claim
49 words
A process according to claim 7, wherein said metal coated surface is a tire cord or a tire bead; and wherein said rubber adhered to said treated surface is selected from the group consisting of natural or synthetic cis-1,4-polyisoprene, polybutadiene, and styrene-butadiene rubber; and wherein said coating is copper.
