Problems solved by technology

The existing polymer self-sealing hot-melt adhesive powder is difficult to meet this requirement, mostly due to the poor adhesion of the polymer self-sealing hot-melt adhesive powder and the unreliable adhesion to the inner wall surface of the vehicle wheel tire, causing the polymer self-sealing hot-melt adhesive powder layer to fall off or fall off. However, it is difficult to achieve the functions and functions of the upgraded vehicle tires without deflation
[0007] 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 hot-melt adhesive powder has been found for a long time

Abstract

The invention relates to a macromolecular self-sealing tire leakage repairing material. The macromolecular self-sealing tire leakage repairing material contains the following ingredients in percentage by mass: 48% of thermoplastic elastomer, 36% of tackifier, 5% of plasticizer, 1% of antioxidant, 1% of cross-linker, 8% of filler and 1% of catalyst. The macromolecular self-sealing tire leakage repairing material provided by the invention has bullet-proof, leakage-proof and prick-resistant properties.

Description

technical field [0001] The invention relates to a polymer material, in particular to a polymer self-sealing tire leak-sealing material used for vehicle tire safety upgrade. Background technique [0002] At present, there are two types of vehicle wheels used in vehicles, one with inner tubes and the other with tubeless vehicles. At present, almost all passenger vehicles use tubeless wheels, and the country requires gradual promotion and use of heavy-duty vehicles. Tubeless vehicle wheels. The tubeless vehicle wheel has the advantages of good heat dissipation, softness, sealing, good riding comfort, and long intervals between inflation and use. However, when the tire of the tubeless vehicle wheel is punctured by a sharp object, the sharp object remains in the vehicle tire , the high-pressure gas in the tire of the vehicle will leak out or blow out at the punctured part; In the two cases of tire burst or rapid leakage, the risk of vehicle accidents is high, and the probabilit...
