Abstract

The invention relates to a macromolecular hot melt adhesive used for safety upgrade of automobile tires and having a self-repair function. The macromolecular hot melt adhesive consists of the following components in percentage by weight: 40 to 60 percent of thermoplastic elastomer, 34 to 51 percent of tackifier, 5 to 8 percent of plasticizer, 0.5 to 1.5 percent of anti-aging agent and / or antioxidant, and 0.2 to 1 percent of cross linker. The macromolecular hot melt adhesive is sprayed on the inner wall of a tire by using an automobile tire adhesive sprayer, any destructive processing is not needed for the inner wall of the tire, the inner wall of the tire is only subjected to release agent removal cleaning and drying treatment, the whole or crown part of the inner wall of the tire is coated with a layer of macromolecular hot melt adhesive of which the thickness is more than 3.5mm, and then the tire can be upgraded to run normally at the temperature of between -40 DEG C and 120 DEG C and has bullet-proof, leak-proof and prick-resistant performance. The invention also discloses a manufacturing method for the macromolecular hot melt adhesive.

Description

technical field [0001] The invention relates to a polymer hot-melt adhesive with self-replenishment function for safety upgrade of ordinary 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-press...
