Problems solved by technology

Existing polymer self-sealing polymer adhesives are difficult to meet this requirement, mostly due to poor adhesion of polymer self-sealing polymer adhesives and unreliable bonding with the inner wall crown surface of automobile tires, resulting in the polymer self-sealing polymer adhesive layer falling off or falling off. Defects, and it is difficult to achieve the function and effect of the upgraded car tires
[0006] In order to solve the above-mentioned problems, relevant manufacturers and research institutes have worked hard to find a solution, but no suitable polymer self-sealing polymer has been found for a long time

Abstract

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.

Description

technical field [0001] The invention relates to a polymer glue, in particular to a self-replenishing sealing polymer glue for automobile tires. Background technique [0002] At present, there are two types of car wheels used in vehicles, one with inner tubes and the other without tubes. At present, almost all of the passenger vehicles use tubeless wheels. The country requires gradual promotion and use of heavy-duty vehicles. Tubeless car wheels. Tubeless car wheels have the advantages of good heat dissipation, softness, sealing and ride comfort, and long intervals between inflation and use. However, when tubeless car tires are punctured by sharp objects, the sharp objects remain in the car tire body, The high-pressure gas of the car tires will leak out or blow out at the punctured part; when the sharp object pierces the car tire and breaks away from the car tire, the high-pressure gas in the tubeless car wheel will leak rapidly. Or two situations of rapid leakage, ...
