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 no suitable polymer self-sealing hot-melt adhesive powder has been found for a long time

Abstract

The invention relates to high-molecular automatic adhering and wrapping rubber powder for improving the safety performance of an automobile tire. The high-molecular automatic adhering and wrapping rubber powder comprises the following components in percentage by weight: 42-62 percent of a thermoplastic elastomer, 34-54 percent of a thickening agent, 3-8 percent of a plasticizer, 0.5-1.5 percent of an antioxidant, 0-15 percent of a filler, 0-1 percent of a catalyst and 0-3 percent of a curing agent. Through the technical scheme provided by the invention, a common automobile tire can be upgraded to be an automobile tire with temperature resistance, pressure resistance, bullet resistance, leakage resistance, explosion resistance and puncture resistance.

Description

technical field [0001] The invention relates to a polymer rubber powder, in particular to a polymer self-adhesive rubber powder for improving the safety 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. 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 market in the eighties of last century was embodied ...
