Disclosed are a pneumatic tire, which exhibits excellent puncture-preventing function while avoiding inconvenience aroused when a sealant layer is formed based on decomposition reaction of polyisobutylene, a process for producing the same and a sealant rubber composition. This pneumatic tire is provided with the sealant layer in a region of the inner surface of the tire which corresponds at least to a tread. The sealant layer is made of an adhesive sealant obtained by heating a rubber composition containing 0.2 to 20 parts by weight of peroxide per 100 parts by weight of a rubber ingredient containing not less than 50 wt. % of polyisobutylene. 5 to 50 parts by weight of a liquid ethylene/α-olefin copolymer, liquid polybutadiene or liquid polyisoprene are added as an adhesive of the sealant layer.
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 pneumatic tire of which self-seal function can be improved while the increase in weight of the tire is minimized. The pneumatic tire having an adhesive sealant layer in the region corresponding to at least a tread portion on the inner side of the tire, the adhesive sealant layer being constituted from a rubber composition containing a rubber component to be decomposed by peroxide and 0.2 to 20 parts by weight of peroxide per 100 parts by weight of the rubber component, in which fibrillated short fibers with an average length of 100 to 5000 μm are mixed and scattered.
摘要:
To provide a tire tube having excellent sealing performance and durability. An inside of a tire includes a peripheral wall having an approximately circular cross-section which is partitioned by a partition wall into an outer peripheral side sealant chamber and an inner peripheral side air chamber. The sealant chamber is filled with a sealant having a thickness in the diameter direction in a range of 0.5 to 1.5 mm.
摘要:
A pneumatic tire having a puncture-preventive sealant layer that suppresses the generation of decomposition gas and is high in viscosity; and a method of producing the same. This pneumatic tire has a sealant layer disposed along the inner surface thereof, in which sealant layer is made of a rubber composition containing a cobalt salt in an amount of 0.07-0.5 parts by weight in terms of cobalt component for 100 parts by weight of rubber containing not less than 80 parts by weight of natural rubber or isoprene rubber.
摘要:
A puncture-durable tire structure has a tire body which is covered with an outer radial ply at the inner side thereof. The outer radial ply is made up of an inner layer and an outer layer that are respectively extended over the bead wires at the edges of the tire body and further extended to a middle position of a rubber side wall of the tire body. The inner side of the outer radial ply is in abutment with an airtight layer which is in turn in abutment with a leakage-proof layer. The leakage-proof layer is further covered with an inner radial ply which has an inner layer and an outer layer. The outer layer of the inner radial ply extends to a tire lip portion of the tire body and the inner layer of the inner radial ply is led over and wound around the bead wires at the tire body and further extends to the upper portion of the rubber side wall. By way of the integral structure of the tire, the tire has a reinforced rubber side wall, and the air inside the tire can be prevented from easily leaking out when the tire is punctured, and the punctured tire can seal by itself so as to improve the driving safety.
摘要:
Pneumatic rubber tire with a puncture sealing feature comprised of an enveloped open network structure containing a sealant composition on the inner portion of the tire.
摘要:
A tubular and generally circular self-sealing tire body composite and method of making the same for use in the construction of tires (for example, radial) having at least a spliceless innerliner layer and a spliceless sealant layer. Desirably, the sealant layer is shorter than the innerliner layer and is centered with respect thereto. The tubular composite can be made by utilizing an innerliner stock and a sealant stock, forming layers therefrom and contiguously contacting said layers to form a contiguous, tubular and generally circular article for subsequent use in building a tire. Additionally, a ply stock may be used, formed into a layer with cord incorporated therein, and contiguously applied to said innerliner layer.
