摘要:
The invention concerns a flexible inner tube comprising a working tread (2) and sidewalls (2) defining a casing, and a sealing membrane (11) covering at least part of the casing, the sealing membrane (11) including at least one elastic material (14) and a puncture-resistant reinforcement (15), the sealing membrane (11) being free relative to the working tread (2) and fixed at one opposite the working tread (2).
摘要:
A pneumatic tire, comprising adhesive sealant applied onto the inner surface thereof, wherein an air barrier membrane is disposed on the inner surface of the tire at least at a tread part, a space part is formed between the air barrier membrane and the inner surface of the tire, and the adhesive sealant is stacked on the space part side surface of the air barrier membrane, whereby an increase in weight can be minimized and a workability in handling the tire can be increased.

摘要:
A sealant laminate (30) comprising a first layer (36) of a sealant material, a first layer (38) of a non-sealant material that is positioned radially outward of the first layer (36) of the sealant material, a second layer (40) a sealant material that is positioned radially outward of the first layer (38) of the non-sealant material, a second layer (42) of a non-sealant material that is positioned radially outward of the second layer (40) of the sealant material, and a third layer (44) of a sealant material that is positioned radially outward of the second layer (42) of the non-sealant material is disclosed. The first and second layers (38, 42) of non-sealant material prevent the first, second, and third layers (36, 40, 44) of sealant material from contacting each other. Also, a pneumatic tire (10) comprising such a sealant laminate (30) positioned between an outer surface (11) and an inner surface (13) of the tire and a method of manufacturing such a tire (10) is disclosed.

The present invention is directed to a pneumatic tire (10) with a built-in sealant layer. The tire (10) comprises an outer circumferential rubber tread (14), a carcass (16), and an innerliner layer (22) disposed radially inwardly from the carcass (16), wherein the tire comprises a built-in sealant layer (20, 20A, 21) comprising a polyurethane based sealant material, wherein the built-in sealant layer (20, 20A, 21) is positioned between the carcass (16) and the innerliner layer (22), and wherein the built-in sealant layer (20, 20A, 21) is a multilayered composite layer, the multilayered composite layer comprising a first polyurethane layer (21), a second polyurethane layer (21 A) and an intermediate layer (20A) positioned between the first and second polyurethane layer (21, 21A). The intermediate layer (20A) comprises at least one of: (A) a non-woven microfiber layer containing polyurethane, (B) particulate pigment, (C) discrete fibers, (D) cured rubber particles, and (E) a woven microfiber layer containing polyurethane.
Also, a method of manufacturing a non-woven microfiber layer containing polyurethane using as intermediate layer (20A) is disclosed.
摘要:
A pneumatic tire comprises a carcass ply (1), two vulcanized rubber composition layers (3) arranged radially inside the carcass ply, and a continuous layer of a sealing material (2) arranged between the two vulcanized rubber composition layers. The sealing material has a viscosity of not more than 6 × 10⁴ poises at 60°C. Bonding portions (1) are formed through the continuous layer, and discontinuously bond two vulcanized rubber composition layers.
摘要:
A self-healing rubber composition comprising: a functionalized elastomer comprising a polymeric backbone chain derived from a monomer comprising at least one conjugated diene monomer and optionally at least one vinyl aromatic monomer, and a functional group bonded to the backbone chain, the functional group comprising a multidentate ligand capable of complexing with a metal ion; and a partitioned metal ion is disclosed. The rubber composition may be used in a pneumatic tire or in a hose, a transmission belt, a drive belt, an air spring, a conveyor belt, a drive track or shoe sole.
