Abstract

The invention relates to macromolecule self-glue rubber for preventing automobile tire flat, comprises the following components in parts by mass (using 100 part by mass of thermoplastic elastomer as the standard): 100 parts of thermoplastic elastomer, 130-140 parts of tackifier, 100-110 parts of plasticizer, 5-5.5 parts of antiaging agent and / or antioxidant, 2-3 parts of foaming agent and 10-12 parts of filler. The macromolecule self-seal rubber after hot-melting is sprayed on the inner wall of the tire by using the automobile tire rubber sprayer, a layer of macromolecule self-seal rubber with thickness of more than 3.5mm is sprayed on all of the inner wall or partial crown type body of the tire by using the automobile tire rubber sprayer without performing any traumatic processing on the inner wall of the tire and only performing cleaning and drying treatment on the inner wall of the tire to remove the release agent, that is, the normal automobile tire is upgraded to realize that the tire can normally work within low temperature of minus 40 DEG C to high temperature 120 DEG C, and has the bullet-proof, leak-proof and puncture-proof performances; and the invention further discloses a manufacturing method of the macromolecule self-seal rubber.

Description

technical field [0001] The invention relates to a polymer self-sealing glue capable of preventing air leakage of vehicle tires and a manufacturing method thereof. 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 of the passenger vehicles use tubeless wheels. The country requires gradual promotion of heavy vehicles. Use tubeless vehicle wheels. Because the tubeless vehicle 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 vehicle wheel is punctured by a sharp object, due to the sharp object remaining in the vehicle In the tire body, the high-pressure gas in the tire of the vehicle will leak out or blow out at the punctured part; when the sharp object pierces the tire of the vehicle and breaks away from the tire of ...
