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 provides polymeric elastic hot-melt adhesive powder. The polymeric elastic hot-melt adhesive powder comprises the following components in percentage by mass: 48% of thermoplastic elastomer, 42% of thickening agent, 6% of plasticizer, 1.2% of antioxidant, 0.8% of catalyst, and 2% of curing agent. The invention provides application of the polymeric elastic hot-melt adhesive powder in security upgrade of an auto tire. According to the application, an auto tire adhesive sprayer is utilized, the inner wall of the auto tire is simply treated by washing with a release agent and drying without any destructive processing, then the polymeric elastic hot-melt adhesive powder is thermally melted and coated on the whole inner wall of the auto tire or coated on the crown-shaped part to form a polymeric hot-melt adhesive layer which is more than 3.5mm in thickness, and thus the common auto tire can be upgraded to be the auto tire with shot-proof, leakproof and puncturing resistant at the temperature ranging from minus 40 to +120 DEG C.
Description
technical field [0001] The invention relates to a polymer material, in particular to a polymer elastic hot-melt adhesive powder 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, and the probability...
