Abstract

The invention provides application and a preparation method of macromolecule self-sealing glue. The macromolecule self-sealing glue is applicable to auto tires. The macromolecule self-sealing hot melt glue is coated on the whole surface of the inner wall of the auto tire or coated on a crown-shaped body part in the upper surface of the inner wall by virtue of the hot melting and spraying technology so as to form an uniform coating being 3.5mm in thickness; the macromolecule self-sealing glue comprises the following components in parts by mass: 100 parts of thermoplastic elastomer, 80 to 100 parts of thickening agent, 10 to 25 parts of plasticizer, and 2 to 4.5 parts of anti-aging agent and / or antioxidant. According to the application, the macromolecule self-sealing glue is coated on the inner wall of the tire without any destructive processing for the inner wall of the tire, the inner wall of the tire is simply treated by washing with a release agent and drying, and then the tire can be upgraded to be able to run normally at the temperature ranging from minus 40 DEG C to +120 DEG C and has the shot-proof, leakproof and puncturing resistant performances.

Description

technical field [0001] The invention relates to the use and preparation method of a polymer self-sealing glue, which is used for safety upgrading of ordinary 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 of heavy-duty vehicles. Use tubeless car wheels. Because the tubeless car wheel has the advantages of good heat dissipation, softness, sealing, comfortable ride, good performance and long interval between inflation and use, but when the tire of the tubeless car wheel is punctured by a sharp object, due to the sharp object remaining on the car In the tire body, the high-pressure gas of the car tire will leak out or blow out at the punctured part; when the sharp object pierces the car tire and breaks away from the car tire, the high-pressure gas in the tu...
