Self-Healing Tires for Improved Durability and Longevity

Preparation device for rubber for self-repairing tires that enables consistent and complete self-healing of tires. The device has a rotating hub assembly with telescopic rods and suction cups to attach to the wheel. It also has a cabin with a heating pipe filled with mixed masterbatch, loop pipes, condensation chambers, and a feeding assembly. The cabin and pipes transport the heated masterbatch to the tire sealant chamber. A pump pressurizes the sealant. The rotating hub captures the wheel edge to stabilize self-repair. The heating, transport, and pressurization steps allow intelligent self-repair of tires to prevent issues like falling, flanging, and accumulation of rubber material.

An anti-puncture tire with self-repairing capability that can prevent tire damage from objects and extend tire life. The tire has a unique rubber composition with modified rubber, repair agent, antioxidant, plasticizer, and anti-aging agent. This composition improves tire properties like strength, durability, and adaptability to extreme temperatures. The self-repairing function is achieved by a post-processing mixture containing adhesive, vulcanizing agent, and accelerator. This mixture is applied after the initial rubber molding to seal punctures and prevent air loss.

A puncture-resistant self-healing tire that can repair itself when punctured to prevent air leakage and extend tire life. The tire has a coating of shape memory nano rubber that can fill and seal punctures when the tire is damaged. When the tire is punctured, the nano rubber deforms to fill the puncture hole. As the tire flexes, the nano rubber returns to its original shape, sealing the puncture. This self-repairing feature prevents air leakage and further damage to the tire from punctures.

Puncture-resistant tire with improved sealing capability and reduced vibration compared to traditional self-sealing tires. The tire has a solidified sealing layer inside that prevents air leakage when punctured. The sealing layer is sandwiched between the inner wall of the tire and a protective layer. The protective layer is cured to solidify and provide rigidity to the sealing layer. This prevents standing waves and vibrations when the tire is rotating at high speed. Additionally, the tire has a mechanism to locate it on the wheel hub when mounted.

Disc-covered self-repairing sealant for tire punctures in electric vehicles that prevents tire deflation and extends tire life. The sealant is a composition of modified polyurethane sealing material and active filler mixed in alcohol. The modified polyurethane contains a diamino-containing thioether compound synthesized from amino and mercaptan groups. The sealant is applied to the inner surface of tires. When a puncture occurs, the sealant fills the hole and seals the tire. The active filler reacts with oxygen to solidify and the modified polyurethane enhances durability and adhesion. The disc cover prevents foreign objects from entering the tire.

Anti-puncture, explosion-proof tire that is maintenance-free and can't be punctured. The tire has an inner tube surrounded by a rubber tire. Inside the rubber tire is an annular groove to hold a ring of inflatable rubber balls. The balls contact each other and support the tire. This prevents punctures because the balls cushion impacts and absorb objects. The balls also prevent explosions by absorbing internal pressure buildup. The balls are hollow and inflatable for durability. The tire doesn't need maintenance since the balls can be replaced if damaged.

A puncture-proof tire design that prevents blowouts and improves tire longevity by sealing punctures internally instead of allowing air to escape. The tire has multiple airtight chambers separated by a sealed ring. The inner wall of each chamber is coated with quick-drying glue. A diaphragm connects the chambers and is reinforced with a woven mesh. If a sharp object penetrates the tire, it gets stuck in the mesh and the glue seals around it. If the penetration is large, the pressure differential forces a conical plug to seal the hole. This prevents rapid air loss and maintains tire integrity. The tire valve has a through-groove with conical ends that a plug slides into. A spring biases the plug closed.

Self-repairing tire for electric motorcycles that can seal punctures and prevent air leaks without needing repairs. The tire has multiple layers: an outer layer with a rubber tread, an inner layer with a repair layer, and a middle layer with a puncture-proof layer sandwiched between the outer and inner layers. The puncture-proof layer prevents penetration, the repair layer seals punctures, and the inner layer seals against air leaks. The tire layers work together to provide self-repairing and leak prevention functionality.

Self-healing safety tire that prevents punctures and improves tire longevity by using a multi-layer construction with integrated puncture repair sections. The tire is molded in multiple layers that are connected by repair components. A 2mm thick polymer compound is sprayed onto the inner surfaces of each layer. When a nail or sharp object penetrates the outer layer, it gets caught in the sprayed compound and prevents further penetration into the inner layers. This protects the inner wall from damage and extends tire life. The outer layers also have vacuum seals between them to reduce tire noise.

Self-healing tire with a structure that automatically releases stress during installation to prevent damage. The tire has a self-healing inner liner made of a layered construction. The innermost layer bonds to the tire wall, the middle layer releases stress during installation, and an outer cover layer protects the liner. This allows the middle stress relief layer to deform and relax during tire mounting instead of tearing or distorting like a solid liner.

Self-healing tire compound that prevents punctures and leaks by repairing itself when the tire is damaged. The compound contains a modified polyurethane rubber, butyl rubber, ethylene-vinyl acetate copolymer, carbonized epoxy polyamide nanofibers, carbon nanotubes, and oil. The modified polyurethane rubber is made by reacting an isocyanate-terminated polyurethane prepolymer with p-acetamidobenzenesulfonamide to form ureido groups. The compound also has carbonized epoxy polyamide nanofibers with calcium hexaaluminate and barite for reinforcing and sealing properties.

Modified conjugated diene copolymer self-healing safety tire with double-layer puncture repair capability. The tire has two puncture-proof layers - one on the inner wall of the outer tire and another on the inner wall of the wheel surface. This provides protection against punctures that can isolate and heal small holes. If a long nail penetrates both layers, the tire repair fluid in the inner tube can seal the hole. If the inner tube is punctured, the polyurethane spokes and wheel surface support the tire to allow driving to a repair location.

A damaged self-repairing puncture-resistant tire that can heal itself when punctured. The tire has a gel layer between the outer and inner layers. When a sharp object penetrates the outer layer, the gel flows into the hole and solidifies, sealing the puncture. If the object pierces both layers, the gel flows into both. A rotating mechanism in the tire compresses and expands an arc-shaped block against the inner layer to smooth and repair the puncture site. It also has anti-skid bumps on the outer surface.

Puncture-resistant tire with self-repairing capability that prevents tire deflation and damage when punctured. The tire has two overlapping layers of soft sealant inside the tire. When a sharp object penetrates one layer, the sealant adheres to it and seals the hole. The sealant layer can move, allowing the sealant to fill the puncture and prevent air leakage. This prevents tire deflation and air loss compared to static sealant layers. The overlapping sealant layers also prevent sealant from settling at the bottom of the tire.

Rubber composition for sealing materials in self-healing tires that improves destructive properties, sealing performance after deterioration, and temporal stability. The composition has a specific balance of zinc oxide, liquid polymer, thiuram-based vulcanization accelerator, dithiocarbamic acid-based vulcanization accelerator, and sulfur relative to the butyl rubber base. It also uses a continuous coating method on tire inner liners with adjustable gap to ensure consistent sealing layer thickness.

Self-sealing tire with a puncture sealant layer between the inner tube and outer tire. The sealant can be injected into the layer and squeezed by the inner tube pressure to distribute evenly. When the outer tire gets a hole, the sealant is squeezed out and contacts air to fill the hole, preventing further leakage. The sealant can be refilled if needed. This allows easy refilling and recycling compared to coating the inner tread.

Self-healing tire with improved structure to better seal punctures and prevent air loss. The tire has a self-repairing layer sandwiched between the inner lining and outer plies. This prevents the self-repairing material from separating or moving during tire construction. A limiting layer, attached to the inner lining, contains the self-repairing material and seals it in place. This layer has inner reinforcement (cordon) to prevent sagging of the self-repairing material. This improves reliability and effectiveness of the self-healing feature compared to separate application of self-repairing material.

Graphene tire with improved puncture resistance compared to conventional tires. The tire has a multi-layer construction with graphene layers sandwiched between other materials. The outer side of the tire has the tread rubber layer. The inner side of the tread layer has a first graphene layer, followed by a repairing sizing material layer, and then a second graphene layer. The inner side of the second graphene layer has a strengthening layer. The graphene layers provide strength and toughness to prevent punctures. The repairing sizing material layer deforms and sticks to piercing objects to seal punctures.

Non-explosive tire design to prevent sudden tire deflation and blowouts when punctured. The tire has a network of small elastic micro airbags inside the tire cavity. When a sharp object pierces the tire and causes air leakage, only a few micro airbags rupture and release air. This slows the air loss compared to a regular tire with puncture. The remaining air keeps the tire pressure and prevents instant deflation. This avoids sudden tire blowouts and improves safety by gradual air loss.

Carbon nanotube self-healing polymer adhesive for tires that improves tire safety and longevity by preventing overheating during high speeds and braking. The adhesive contains carbon nanotubes dispersed in a polymer matrix. The nanotubes have high thermal conductivity and vertical heat transfer. By evenly distributing the nanotubes in the adhesive, heat generated during tire operation can be quickly transferred to the outside, reducing temperature accumulation and prolonging tire life. The adhesive is prepared by ultrasonically dispersing the nanotubes in oil, then mixing with resin, butyl rubber, and styrene-butadiene rubber. The nanotubes are stirred at increasing speeds to evenly distribute them.
