Filed:

Jun 30, 1980

Appl. No.:

6/164127

Inventors:

Walter R. Hausch - Akron OH

Assignee:

The Firestone Tire & Rubber Company - Akron OH

International Classification:

F16L 1112
B32B 2504
B32B 2512

US Classification:

428 36

Abstract:

A process and composition for applying and bonding a curable polymer or prepolymer, for example, an amine curable polymer or prepolymer, at ambient temperatures to the surface of a cured elastomer substrate. The elastomer article or substrate is treated with an organic oxidant such as one selected, for example, from the group consisting of N-halosulfonamides, N-halohydantoins, N-haloamides, N-haloimides, and the various isomers of mono-, di-, and trichloroisocyanuric acid. A composition of a curable polymer or prepolymer is prepared with a curing agent. To the curing agent and curable polymer or prepolymer composition is added a polar solvent which is mixed with the resulting blend or mixture and added to the treated elastomer surface; said polymer or prepolymer cures at ambient temperature and becomes bonded to said elastomer. The application is relatively easy, since the entire mixture is a liquid and can be applied in situ. The invention is particularly suitable for repairing various damaged elastomer articles such as tires (especially off-the-road), conveyor belts, hoses, preparation of caulking or sealing compounds, and especially in bonding tire lugs or tire treads to a tire carcass.

US Classification:

152353R

Abstract:

A process and composition for applying and bonding an indicia which is curable at ambient temperatures to a cured elastomer substrate. The substrate is treated generally at ambient temperatures with organic oxidants selected from the group consisting of N-halosulfonamides, N-halohydantoins, N-haloamides, N-haloimides, and the various isomers of mono-, di-, and trichloroisocyanuric acid. The indicia which is generally a urethane polymer or prepolymer is blended with an amine curing agent. A polar solvent is added to the amine curing agent and the amine curable polymer or prepolymer composition and mixed with the resulting blend or mixture applied to the treated elastomer surface in the form of an indicia so that said polymer or prepolymer cures at ambient temperature and is bonded to said elastomer. The invention is particularly suitable for applying indicia to various elastomer articles such as tires, conveyor belts, hoses, floor mats, sporting goods, and the like. An advantage of the invention is that the indicia can be made utilizing liquid components, mixed and applied at the site.

International Classification:

C08C 1908

US Classification:

525375

Abstract:

Uncured rubber compositions containing fused aromatic furazan oxides exhibit improved processability and reduced viscosity. Useful furazan oxides have both carbons of the furazan ring as part of a fused aromatic ring and include benzofurazan oxide and its methyl and methoxy analogs. Improvements in processability, green strength and liquification of NR can be achieved through use of these furazan oxides in uncured rubber compositions.

US Classification:

428 36

Abstract:

The repair of a reinforced elastomer article having a hollow therein relates to utilizing an amine curable polymer or prepolymer and a cured elastomer patch. The hollow in the elastomer as well as the areas juxtaposition to the patch is coated with a treating agent. The amine curable polymer or prepolymer is then applied to the hollow as well as to the area between the patch and the elastomer and cured at ambient temperature. One area of use is in the repair of tires.

US Classification:

524255

Abstract:

Combinations of para-phenylene diamines and para di(nitroso) arenes act synergistically in guayule rubber-based compositions to protect them against oxidative degradation. A typically useful diamine is N-(1,3-dimethylbutyl)-N'-phenyl-phenyl-p-phenylene diamine and a useful arene is para-di(nitroso)benzene. Vulcanizable compositions, as well as articles made therefrom, are within the scope of the invention.
