Abstract:
Provided is a self-sealing tire that is excellent in the effect of reducing adhesion of foreign materials to the sealant layer, sealing performance, and road noise-reducing properties while maintaining the balance between them. The present invention relates to a pneumatic tire, including: a sealant layer located radially inside an innerliner; and a sound-absorbing layer located radially inside the sealant layer, the sound-absorbing layer being formed by applying a porous sound-absorbing material to the inner periphery of the sealant layer.
Abstract:
The invention relates to puncture resistant leakless material for tubeless tire and its manufacturing and spray coating methods. The object of the invention is to provide a puncture resistant leakless material and its manufacturing and spray coating methods. The puncture resistant leakless material resists high temperature, low temperature, oil and water, has high leakproof property, costs low, and could keep running in a high speed for a very long time when a sharp object punched through, or when the sharp object in the tire. The puncture resistant leakless material has high tear resistance, resilience and long service life. When a sharp object punched through, or when the sharp object in the tire, tire using the material of the invention could keep running in a high speed for a very long time without leakage or dropping of pressure. The raw materials for manufacturing the puncture resistant leakless material for tubeless tire of the invention do not need vulcanization, which quite saves energy and costs during the manufacture.
Abstract:
The present invention provides a tire puncture sealant including a rubber latex and 1,3-propanediol, which has a reduced viscosity at low temperatures, has better injectability at low temperatures, and is also excellent in storage stability, initial sealing performance, and seal retention performance.
Abstract:
The present disclosure provides a safety tire having a puncture-resistant, bulletproof, and leakproof capability between about −45° C. to about 120° C. without any damaging process to the inside wall of the tire, but just by spray coating a layer of leakproof and hermetically-repairing macromolecular material with a thickness of about 2 mm to about 8 mm to the inside wall of the tire that does not have an inner tube. The present disclosure also provides the components of the leakproof and hermetically-repairing macromolecular material and the method to prepare the puncture-resistant bulletproof and leakproof safety tires.
Abstract:
Pneumatic tire including a sealant material composition providing puncture sealing property within the sealant material composition includes a compound containing a diphenyldisulfide structure therein.
Abstract:
Disclosed are a sealing material comprises a powdered material into which a rubber base sealing material with a viscosity of 20 to 200 Pa·s/100° C. is pulverized at a temperature lower than, or equal to, a brittle temperature of the rubber base sealing material, and a method of applying the sealing material, which comprising applying the powdered material to a surface, intended to be coated with the powered material, by a spay coating process.
Abstract:
A bond of a rubbery component to a virgin surface of a tire's cured innerliner which virgin surface has never been contaminated by the remnants of a release agent left after buffing with a wire brush and solvent-cleaning the cured innerliner, is unexpectedly stronger than a bond of the component to the contaminated but nullcleaned surfacenull, cleaned as indicated. As an alternative, buffing with a wire brush results in a textured surface that impairs adhesion of a balance pad. Therefore, a pneumatic tire is provided with a virgin surface protected against contamination by a release agent at the curing temperature of the tire; protection is provided by a self-supporting barrier film of sulfur non-vulcanizable, expandable, thermoformable synthetic resinous material; and, a method is provided for maintaining a virgin cured surface within all or part of either the exterior or interior of a pneumatic tire's rubber carcass which is conventionally cured. The barrier film which is substantially inextensible at ambient temperature, is removable without tearing into pieces from the protected surface of the cured tire. When the interior surface is provided by an innerliner, any component to be included within the interior of the carcass may be adhesively secured to the virgin surface of the innerliner more securely than has been heretofore possible.
