Self-Healing Tires

Self-regenerating multilayer materials that can repair and reinforce their own layers over time. The materials have interlayer films containing particles that form an assembly around them. The particle assembly has a lower melting point than the layer materials. When the multilayer is heated, the interlayer films melt, allowing the particles to flow and fill any gaps between the layers. This repairs delaminations and reinforces the cohesion between layers. The films can be placed between existing layers during manufacture or added later to repair damaged multilayers.

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.

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.

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.

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.

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.
