    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: 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: This invention is based upon the concept of modifying the surface of silica with a metal, such as titanium or zirconium, which will catalyze silanol condensation reactions on the surface of the silica. In other words, modifying the surface of silica with titanium or zirconium provides a catalyst for the silanol condensation reaction between the silica surface and silane coupling agents used in silica filled compounds. The utilization of such metalated silica as a filler in rubber compositions results in improved polymer filler interaction and in turn improved physical properties. For instance, such surface metalated siliceous fillers can be used in tire tread compounds to attain improved rolling resistance and treadwear without compromising traction characteristics. The present invention more specifically discloses an elastomeric composition which is comprised of (1) a rubbery polymer, (2) a silica coupling agent, and (3) a surface metalated siliceous filler. The subject invention further reveals a tire which is comprised of a generally toroidal-shaped carcass with an outer circumferential tread, two spaced beads, at least one ply extending from bead to bead and sidewalls extending radially from and connecting said tread to said beads, wherein said tread is adapted to be ground-contacting, and wherein said tread is comprised of (1) a rubbery polymer, (2) a silica coupling agent, and (3) a surface metalated siliceous filler.
