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

The invention relates to high polymer rubber powder used for a car tyre. The high polymer rubber powder used for the car tyre comprises the following components in percentage by weight: 45% of thermoplastic elastomer, 40% of tackifier, 5% of plasticizer, 1% of antioxidant, 1% of cross-linking agent and 3% of foamingagent. The high polymer rubber powder used for the car tyre disclosed by the invention is applied to security upgrading of the vehicle tyre; a vehicle tyre glue sprayer is utilized, no damage processing is carried out on the inner wall of the vehicle tyre, only release agent removing, cleaning and drying treatments are carried out onto the inner wall of the vehicle tyre; after high polymer rubber powder used for the car tyre is thermally melt, a high polymer hot melt rubber layer with thickness being greater than 3.5mm is sprayed on the whole part or the crown type part of the inner part of the vehicle tyre, so that the common vehicle tyre can be upgraded into a tyre can resist temperature in a range of a low temperature (-)40 DEG C to a high temperature (+)120 DEG C, and therefore, the vehicle tyre is bulletproof, leakage-proof and puncture-resistant.
Description
technical field [0001] The invention relates to a polymer material, in particular to a polymer rubber powder used for vehicle tire safety upgrading. 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 probability of car crashes and fat...
