The invention provides a self-repairing rubber strip for a tire, which comprises four layers from outside to inside, namely an A-layer penetration-resistant layer, a B-layer elastic layer, a C-layer pressure-resistant layer and a D-layer protective layer. The component of the layer A is thermoplastic elastomer, softener, antioxidant and uvioresistant agent 770; the component of the layer B is polyamide resin, polyether ester fiber, filler, coupling agent, antioxidant and rubber; the component of the layer C is rubber, thermoplastic elastomer, resin, softener, filler and antioxidant; the layer D is release paper or PE film. The tire self-repairing adhesive tape prepared by the invention is environment-friendly in preparation process, has good elongation at break, rebound resilience and low air permeability, and enables the tire to have a good protection and self-healing function on a severe road surface. |
