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 discloses a macromolecule hot-melting rubber with a self-seal function, comprises the following components in parts by mass: 55% of thermoplastic elastomer, 38% of tackifier, 5% of plasticizer and 2% of antioxidant. The macromolecule hot-melting rubber with the self-seal function is used in the application for the security upgrade of the automobile tire, after the macromolecule hot-melting rubber with self-seal function is hot-melted, a layer of macromolecule hot-melting rubber with a self-seal function with thickness of more than 3.5mm is sprayed on all of the inner wall or partial crown type body of the tire by using the automobile tire rubber sprayer without performing any traumatic processing on the inner wall of the tire and only performing cleaning and drying treatment on the inner wall of the tire to remove the release agent, that is, the normal automobile tire is upgraded to realize that the tire can normally work within low temperature of minus 40 DEG C to high temperature 120 DEG C, and has the bullet-proof, leak-proof and puncture-proof performances.

Description

technical field [0001] The invention relates to a polymer rubber powder, in particular to a polymer hot-melt adhesive with a self-sealing function used for safety upgrading of vehicle tires. 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, ...
