Abstract

The invention relates to a polymer self-sealing hot melt adhesive capable of providing leakproof safety performance to a vehicle tire and a preparation method and application thereof. The polymer self-sealing hot melt adhesive comprises the following components in parts by weight: 100 parts of thermoplastic elastomer, 100-150 parts of tackifiers, 80-110 parts of plasticizers, and 4 parts of anti-aging agents and / or antioxidants. By using a rubber tire glue sprayer, the polymer self-sealing hot melt adhesive disclosed by the invention is sprayed on the inner wall of the tire, and is free of traumatic processing on the inner wall of the tire, just the inner wall of the tire is subjected to cleaning and drying treatment to remove a release agent, a layer of polymer self-sealing hot melt adhesive of which the thickness is greater than 3.5mm is sprayed on the whole inner wall or the crown body part of the tire, so that the tire can be upgraded to normally run within the range from the low temperature of -40 DEG C to the high temperature of +120 DEG C. The polymer self-sealing hot melt adhesive has bulletproof property, leakproof performance and punctured resistance. A method for manufacturing the polymer self-sealing hot melt adhesive is also disclosed by the invention.

Description

technical field [0001] The invention relates to a polymer self-sealing hot-melt adhesive that can make vehicle tires have leak-proof safety performance, its manufacturing method and application. 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 a...
