Abstract

The invention relates to macromolecular self-sealed hot melt adhesive powder with temperature resistance, pressure resistance and explosion-proof performance for an automobile tyre. The macromolecular self-sealed hot melt adhesive powder comprises the following components in percentage by weight: 42-62% of a thermoplastic elastomer, 34-54% of a tackifier, 3-8% of a plasticizer, 0.5-1.5% of an antioxidant and 0-1% of a catalyst. By the macromolecular self-sealed hot melt adhesive powder for temperature resistance, pressure resistance and explosion-proof performance of the automobile tyre, the macromolecular self-sealed hot melt adhesive powder is sprayed on the inner wall of the tyre by an automobile tyre glue sprayer, and the inner wall of the tyre is not destructively processed, and is only subjected to release agent removal and drying treatment. After the macromolecular self-sealed hot melt adhesive powder is hot-melted, the macromolecular self-sealed hot melt adhesive layer which is thicker than 3.5mm is sprayed on the whole or the crown part of the inner wall of the tyre, so that the common automobile tyre is upgraded to the tyre which can normally work from a low temperature of -40 DEG C to a high temperature of 120 DEG C. The tyre has the performances of bullet resistance, leak prevention, explosion-proof performance and prick resistance.

Description

technical field [0001] The invention relates to a polymer rubber powder, in particular to a polymer self-sealing hot-melt rubber powder with temperature resistance, pressure resistance and explosion-proof performance 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 wheel. The tubeless car wheel has the advantages of good heat dissipation, softness, sealing, good riding comfort, and long intervals between inflation and use. , the high-pressure gas in the tire of the car tire will leak out or blow out at the punctured part; Blowout or two situations of rapid leakage, the risk of automobile accidents is high, and the probability of car crashes and fatalities is high. [0003] Since the main technology in the ...
