Abstract

The invention relates to a high-molecular hot-melt adhesive for security upgrade of an automobile tyre. The high-molecular hot-melt adhesive comprises the following components in percentage by weight: 40%-60% of thermoplastic elastomers, 34%-51% of thickening agents, 5%-8% of plasticizing agents, 0.5%-1.5% of anti-aging agents, 0.2%-1% of cross-linking agents and 3%-5% of filling agents. By using a glue sprayer of the automobile tyre, the high-molecular hot-melt adhesive is sprayed to the inner wall of a tyre after being hot-melted, the inner wall of the tyre is only subjected to mould release agent removal washing and drying treatment without being subjected to any damaging processing; the tyre can be upgraded to normally operate between low temperature of -40 DEG C and high temperature of +120 DEG C by spraying a layer of the high-molecular hot-melt adhesive with the thickness more than 3.5 mm on the integral part or crown type body part of the inner wall of the tyre, and the tyre has bullet-proof, leakage-proof and anti-puncturing properties. The invention also discloses a manufacturing method of the high-molecular hot-melt adhesive.

Description

technical field [0001] The invention relates to a polymer hot-melt adhesive capable of preventing air leakage of automobile tires and a manufacturing method thereof. 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 tubeless car...
