摘要:
A tire with a built-in self-sealing layer includes an external rubber tread, a carcass reinforcer, a gastight layer arranged towards an inside location relative to the carcass reinforcer, an anti-tack layer arranged furthest towards the inside, location and a self-sealing layer adjacent to the anti-tack layer and arranged towards the inside location relative to the gastight layer. The anti-tack layer includes particles with a shape factor (F=L/E) higher than 5. L represents a first dimension, and E represents a second dimension normal to the first dimension, with L being a longer dimension than E.

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:
The present invention relates to a tire puncture sealant and a pneumatic tire containing such puncture sealant as a built-in puncture sealant. The sealant composition contains silica reinforcement and butyl rubber depolymerized in the presence of a balanced and cooperative combination of organoperoxides comprised of a minor amount of 4,4-di(tertiary butylperoxy) valerate depolymerization initiator and a major amount of dicumyl peroxide depolymerization propagator, the combination of which has been observed to have a synergistic effect.

摘要:
[Problem to be Solved] To provide a method of treating a sealing compound that can efficiently separate and recover a used sealing compound into rubber latex and a liquid constituent, and also simplify the treatment of the rubber latex and liquid constituent separated from the used sealing compound.[Solution] Provided is a method of treating a sealing compound, in order to recover from the inside of a pneumatic tire the sealing compound that was used for repairing a puncture, the sealing compound including an aqueous solution having at least rubber latex dispersed therein, the method comprising: solid-liquid separating, by injecting a treating agent into the inside of a pneumatic tire into which the sealing compound was injected, the treating agent comprising at least one of a salt that is a reaction compound of an acid and a base and/or a water-soluble organic solvent, mixing the treating agent with the sealing compound inside the pneumatic tire, and aggregating and solidifying the rubber latex in the sealing compound.
摘要:
The present invention relates to a pneumatic tire which contains a built-in zoned puncture sealant layer. The zoned puncture sealant layer is comprised of organoperoxide depolymerized butyl rubber zones comprised of a central primary zone and lateral zones joined together to form a unitary sealant layer. The sealant of the lateral zones of the sealant layer is of a higher storage modulus (G′) than the sealant of the central zone.
摘要:
A pneumatic tire is disclosed, which comprises a bubble-containing adhesive composition layer as a puncture prevention layer or a puncture prevention layer formed by covering at least one surface of a sheet-like foamed body with a nonporous adhesive composition layer, disposed in the inner surface of a tire main body. This pneumatic tire having the puncture prevention layer in the tire inner surface is adapted to reduce the weight of the tire.
