Most of tires used at the present stage are pneumatic vacuum tires, and in the daily driving process, the tires can be punctured by nails or sharp hard substances on the road surface, so that acute air leakage can be caused, the vehicle is cast by light people, and the vehicle is overturned by heavy people. The traditional tire patching method has the advantages that the vehicle is static, the wheels are disassembled, the inner tube is taken out when the inner tube is arranged, the trouble is caused, a large amount of time is wasted, and the working efficiency is low. Therefore, the technology of repairing the tire has become mature and is well recognized, and when the tire is punctured and the tire leaks, the tire repairing glue is connected to the tire, and the valve of the tire repairing glue is pressed, so that the compressed air is automatically added into the tire, and meanwhile, the tire repairing glue is also injected. After the tire pressure of the tire is normal, the automobile can be driven to run on the road again. Generally, after a tire is filled with a single puncture sealant, if the liquid in the tire does not volatilize and leak, the tire is not repaired even if the tire is punctured again later. The tyre repairing glue solution in the tyre can automatically repair the leak on the tyre under the pressure action. However, various products on the market still have a lot of problems, for example, most tire repair glue solutions only temporarily stabilize air pressure, so that an automobile can run to a nearest automobile maintenance station, some tire repair glue solutions corrode and damage tires, potential safety hazards exist, the tire repair speed is slow, and meanwhile, some tire repair glue solutions have poor anti-freezing effect; some tire repair glue solution can be dried up in the tire or frozen in cold weather, but the repair effect is lost, and the inner wall of the tire can be damaged; some tyre repairing glue is made of various natural fibers or asbestos fibers and chemicals, the fibers can be gradually agglomerated in the tyre, the tyre repairing effect is lost, the inner wall of the tyre can be abraded, the vehicle can vibrate during driving, and the market development requirements can not be met.
