A method of manufacturing a tire, the method comprising the steps of providing a cured tire subassembly, the subassembly including a first bead and a second bead, a cured carcass layer extending from the first bead to the second bead, and an optional cured innerliner disposed on the carcass layer; and applying an air barrier composition to the cured carcass layer, or to the cured innerliner if present, to form an air barrier layer.

A method of preparing a green tire innerliner, the method comprising mixing one or more vulcanizable rubbery polymers, less than 0.75 parts by weight zinc oxide, less than 0.75 parts by weight magnesium oxide, and less than 0.75 parts by weight sulfur, per 100 parts by weight rubber, to form a vulcanizable mixture and extruding the mixture to form a green tire innerliner.

Methods for treating the surface of a cured inner liner are disclosed. By use of these methods a treated, cured inner liner is produced which has a lower surface with increased adherability to other materials (e.g., adhesives). Treated, cured inner liners resulting from such methods as well as tires containing the treated inner liners.

A pneumatic tire including an innerliner member applied on a tire inner circumferential surface, the innerliner member being constituted from an at least three-layer structure including a film having a main component of a thermoplastic resin or a thermoplastic elastomer containing a blend of a thermoplastic resin and an elastomer, and rubber sheets layered on both sides of the film; and a lap splice portion in which tire circumferential direction end portions of the film are overlapped with the rubber sheets inbetween. The rubber sheet on the tire cavity side of the innerliner member disposed on the tire cavity side in the lap splice portion is formed longer along the tire circumferential length than the film adjacent thereto.

The present invention is a strip of a thermoplastic elastomer composition to be wound spirally on a cylindrical drum to form an inner liner for a tire. The strip is composed of a layer stack of a first layer made of a thermoplastic elastomer composition containing 0.1 part by mass to 50 parts by mass of an organic derivative of clay mineral relative to 100 parts by mass of a styrene-isobutylene-styrene triblock copolymer, and a second layer made of a thermoplastic elastomer composition containing at least one of a styrene-isoprene-styrene triblock copolymer and a styrene-isobutylene diblock copolymer. The strip has a strip main body with a thickness of 0.05 mm to 1.0 mm and ear portions with a thickness thinner than the thickness of the strip main body and a width of 0.5 mm to 5.0 mm disposed on opposite sides thereof.

An embodiment of the present invention provides an air injection valve-integrated spray for spraying and applying polyurethane foam to a desired portion of a tire. The spray includes a polyurethane foam chamber disposed at an end of a coupling portion and keeping polyurethane foam under pressure and an air delivery chamber delivering air injected from an air injection valve to a breaking portion of the polyurethane foam chamber, in which the breaking portion of the polyurethane foam chamber is broken by air coming out of the air delivery chamber, so the polyurethane foam is sprayed.

A pneumatic tire includes an inner liner including a vulcanized rubber composition such that a number of voids each having a volume of 4.19 μm.sup.3 or more per 8,000,000 μm.sup.3 in the vulcanized rubber composition is 2 or less in an environment of 60° C. under an atmospheric pressure, and that the vulcanized rubber composition has an air permeation coefficient of 0.95×10.sup.−10 cm.sup.3.Math.cm/(cm.sup.2.Math.s.Math.cmHg) or less when measured using a differential pressure method in the environment of 60° C.

A method of preparing a tire with self-sealing properties, the method including the steps of providing a cured tire, the tire including a first bead, a second bead, a carcass layer extending from the first bead to the second bead, and an optional innerliner layer disposed interior to the carcass layer; directly or indirectly applying a sealant composition to at least a portion of the carcass layer or to at least a portion of the optional innerliner; and directly applying an air barrier composition to at least a portion of the carcass layer or to at least a portion of the optional innerliner.

The invention discloses a method for manufacturing a bulletproof and explosion-proof tubeless tire, first, the innerliner is attached to the carcass cord ply to make the carcass innerliner, and then the steel wire braided layers and the intermediate rubber layers are laminated to each other to make an explosion-proof layer, using a first stage building machine to complete the first stage forming of the carcass innerliner, explosion-proof layer and belt to obtain a semi-finished embryo, and then using a second stage building machine, the semi-finished embryo and the tread slab base are formed in the second stage to obtain the embryo, which is baked and stored for 8˜96h and then vulcanised to obtain a bulletproof and explosion-proof tire; through the second stage forming process, the invention solves the problem that the explosion-proof layer is difficult to form due to the excessively hard metal material when making the embryo.

Techniques for managing real-time business event analysis and monitoring are provided. In some examples, a logical request may be received at a business intelligence server configured with a continuous query service. Additionally, the continuous query service may be configured to translate the logical request into a physical request. Further, business intelligence information may be provided based at least in part on querying against an event data stream with a continuous query configured based at least in part on the physical request translated by the continuous query service.
