Self-sealed tire adhesive and preparation method thereof

Abstract

The invention discloses a self-sealed tire adhesive for security upgrading of an automobile tire. The adhesive comprises the following components in parts by mass (taking 100 parts by mass of thermoplastic elastomer as the standard): 100 parts of thermoplastic elastomer, 140-160 parts of tackifier, 100-120 parts of plasticizer, 4 parts of anti-aging agent and / or antioxidant 4 and 6-8 parts of filling agent. The self-sealed tire adhesive disclosed by the invention is sprayed onto the inner wall of the tire by using an automobile tire adhesive spraying machine, the inner wall of the automobile tire is prevented from generating any damage processing but is only subjected to washing by a demolding agent and drying treatment, the self-sealed tire adhesive that the thickness is greater than 3.5mm is sprayed on the whole inner wall or the crown-shaped part of the automobile tire, thus the ordinary automobile tire can be upgraded into a bulletproof, anti-leakage and pricking-resisting automobile tire which can work normally within a temperature range from a low temperature of minus 40 DEG C to a high temperature +120 DEG C. The invention further discloses a preparation method of the self-sealed tire adhesive.

Description

technical field [0001] The invention relates to a tire self-sealing glue used for safety upgrading of ordinary 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 th...
