摘要： In one embodiment, a pneumatic tire having a built-in sealant layer, before cure, includes an unvulcanized pneumatic tire assembly having an outer circumferential rubber tread and a supporting carcass. A precursor sealant layer is situated between the supporting carcass and an innermost rubber inner liner. The precursor sealant layer includes a non-flowing polyurethane composition that is neither gel-like nor tacky and is self-supporting. The precursor sealant layer, during curing of the unvulcanized pneumatic tire assembly, thermally degrades so as to provide a gel-like and tacky, self-healing polyurethane composition which defines the built-in sealant layer. The resulting tire, with its innermost polyurethane composition, allows for elimination or reduction in blister formation by reducing or elimination the amount of gases typically given off by organoperoxide-butyl based sealant layers, such as when the tire is at its running temperature. Consequently, the thickness of the inner liner may be reduced.

摘要： A pneumatic tire and method of making is disclosed, which includes, in one embodiment, an outer tread and a barrier layer disposed inwardly of the outer tread. The barrier layer includes a dynamically vulcanized alloy, which has an engineering resin as a continuous phase and at least a partially vulcanized rubber as a dispersed phase, and an inner surface and an outer surface. A tire layer, e.g., a ply layer, is situated adjacent at least one of the inner or outer surfaces of the barrier layer. The tire layer includes a rubber formulation having 100 parts of natural rubber, a synthetic rubber, or blends or combinations thereof, 1-10 phr of a melamine derivative, e.g., hexamethoxymethylmelamine, and at least one reinforcing filler. The tire is devoid of an adhesive layer between the barrier layer and the tire layer, and the tire layer adheres directly to the barrier layer after tire cure.

摘要： The present invention is directed to a pneumatic tire having a built-in sealant layer and its preparation. In one embodiment, the pneumatic tire includes an outer circumferential rubber tread and a supporting carcass. An optional rubber inner liner is disposed inwardly from the supporting carcass. A built-in sealant layer is disposed inwardly from the rubber inner liner. The built-in sealant layer provides self-sealing properties to the pneumatic tire. A gas permeable layer is situated adjacent an innermost rubber inner liner and the built-in sealant layer. The innermost rubber inner liner has a plurality of spaced apart openings extending therethrough, which are covered by the gas permeable layer. The tire, with its innermost inner liner with holes and the gas permeable layer, allows for elimination or reduction in blister formation in the tire by permitting gas from the built-in sealant layer to escape.

摘要： A composite of a flexible, releasable backing having discrete portions of thin, sulfur vulcanizable, carbon black filled adhesive rubber composition thereon is used for adhering a tire tread splice and other applications in assembled rubber articles. The adhesive composition comprises a rubber composition containing a sulfur curative together with carbon black, processing oil, and tackifier resin. The invention is further directed to a method of preparing a tire having tread ends joined together with said discrete adhesive composition. The adhesive is applied to the tread from its releasable backing so that tacky adhesive need not be physically contacted by an operator or machine.

摘要： A carbon black filled crosslinkable rubber composition can be marked or identified with a contrasting colored crosslinkable composition. The colored crosslinkable composition is desirably thin (e.g. about 0.1 to about 10 mil thick) and is substantially free of solvent. To facilitate mechanized application of the colored crosslinkable composition it is applied from a releasable material in the form of film, filament or fiber that can be reused or recycled.
