Abstract

The invention discloses application and preparing method of a macromolecular self-sealing hot melt adhesive which is used for an automobile tire. The macromolecular self-sealing hot melt adhesive is sprayed on the whole or the crown part of the inner wall surface of the automobile tire through a hot melt spray technology, and a uniform coating which is more than 3.5 mm in thickness is formed, wherein the macromolecular self-sealing hot melt adhesive consists of the following ingredients according to ratio by weight: 40-60% of thermoplastic elastomer, 34-51% of a tackifier, 5-8% of a plasticizer and 0.5-1.5% of an anti-ageing agent/antioxidant. The macromolecular self-sealing hot melt adhesive is sprayed on the inner wall of the tire, any destructive processing is not required to be carried out on the inner wall of the tire, and the removal washing of a mold release agent and drying processing are carried out on the inner wall of the tire only, the tire can be updated into a such tire capable of normally working in a range from the low temperature of -40 DEG C to the high temperature of 120 DEG C, and the tire has bullet-proof, leakage-proof and stab-proof performance.

Description

Technical field [0001] The invention relates to the use of a polymer self-sealing hot melt adhesive and a preparation method thereof, which are used for the safety upgrade of ordinary automobile tires. Background technique [0002] At present, there are two types of car wheels used in vehicles, one with tube wheels and the other with tubeless wheels. At present, almost all of the passenger vehicles use tubeless wheels, and the national requirements for heavy vehicles are gradually promoted. Use tubeless car wheels. Because tubeless car wheels have the advantages of good heat dissipation, softness, sealing, riding comfort, good performance and long time between inflation and use, but when tubeless car wheels are punctured by sharp objects, the sharp objects remain in the car. In the tire body, the high-pressure gas of the car wheel tire will leak or blow out at the puncture site; when the sharp object pierces the car tire and separates from the car tire, the high-pressure gas ins...
