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 automobile wheel tire, causing the polymer self-sealing hot-melt adhesive powder layer to fall off or off-edge defects, it is difficult to achieve the function and effect of the upgraded car 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 for a long time no suitable polymer automatic adhesive explosion-proof sealing powder has been found.

Abstract

The present invention relates to automatic adhering wrapping explosion-prevention polymer sealing rubber powder for improving vehicle tire performances. The automatic adhering wrapping explosion-prevention polymer sealing rubber powder comprises, by weight, 40-50% of a thermoplastic elastomer, 40-50% of a tackifier, 5-8% of a plasticizer, 0.5-1.5% of an anti-aging agent, 3-5% of a filler, and 1-3% of a foaming agent. With the technical scheme, the ordinary vehicle tire can be upgraded to the vehicle tire with characteristics of high-temperature resistance, low-temperature resistance, bullet resistance, leakage resistance and puncture resistance.

Description

technical field [0001] The invention relates to a polymer rubber powder, in particular to a polymer self-adhering explosion-proof sealing rubber powder for improving the performance of 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 wheels. Tubeless car wheels have the advantages of good heat dissipation, softness, sealing and ride comfort, and long intervals between inflation and use. The high-pressure gas in the tire of the car tire will leak outwards or blow out at the punctured part; If there are two situations of tire or 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 market in the eighties of la...
