Self-repairing sealing polymer gel for repairing of automobile tire

The invention relates to a self-repairing sealing polymer gel for repair of an automobile tire. The self-repairing polymer gel mainly comprises the following components by weight percent: 30-38 percent of styrene thermoplastic elastomer, 40-45 percent of thermoplastic polymer resin with the relative molecular weight of 200-2000, 5-15 percent of plasticizing and softening component, 1-2 percent of anti-aging antioxidant component, 0-2 percent of catalytic promoter component and 0-8 percent of filling temperature-resistant component. The macromolecular self-repairing sealing hot melt polymer gel provided by the invention is sprayed on the surface of the inner wall of an automobile tire to form a uniform coating of not less than 3.5 mm thick, and therefore plays the roles of resisting against leakage, pricking and bullet and can be used in military vehicles or civil vehicles; and the self-repairing sealing polymer gel for repair of an automobile tire has the advantages that the raw materials are conveniently purchased and low in cost, and the elasticity, the tensile resistance, the self-repairing sealing effect are good and the like, and provides an effective technical support for improving the use performance of products and reducing the use cost of users.
