Elasticity-proof, leakage-proof and prick-resistant macromolecular material for automobile tyres

Abstract

The invention relates to an elasticity-proof, leakage-proof and prick-resistant macromolecular material for automobile tyres. The elasticity-proof, leakage-proof and prick-resistant macromolecular material for automobile tyres comprises the following components in percentage by weight: 42-62% of a thermoplastic elastomer, 34-54% of a tackifier, 3-8% of a plasticizer, 0.5-1.5% of an antioxidant and 0-3% of a curing agent. According to the technical scheme provided by the invention, a common automobile tyre can be upgraded to into a high-temperature-resistant, low-temperature-resistant, elasticity-proof, leakage-proof and prick-resistant automobile tyre.

Description

technical field [0001] The invention relates to a polymer material, in particular to a polymer material with bulletproof, leakproof and puncture-resistant properties for automobile tires. 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 and use of heavy-duty vehicles. Tubeless car wheel. The tubeless car wheel has the advantages of good heat dissipation, softness, sealing, good riding comfort, and long intervals between inflation and use. , the high-pressure gas in the tire of the car tire will leak out or blow out at the punctured part; Blowout or two situations of rapid leakage, the risk of automobile accidents is high, and the probability of car crashes and fatalities is high. [0003] Since the main technology in the market in the eighties of last century was embodied...

Problems solved by technology

[0004] 1. Since isoprene rubber, butene rubber, and silicone rubber are important members of synthetic rubber, they have a wide range of applications and high raw material prices;

[0005] 2. The activity and anti-aging properties of this type of rubber cannot achieve substantial technological breakthroughs, and it is difficult to use them in the harsh working environment of automobile wheels for a long time;

[0007] 4. The raw materials of isoprene rubber, butene rubber and silicone rubber used, cost and industrialization development are the factors restricting the promotion

The existing polymer self-sealing hot-melt adhesive powder is difficult to meet this requirement, mostly due to the poor adhesion of the polymer self-sealing hot-melt adhesive powder and the unreliable adhesion to the inner wall surface of the automobile wheel tire, causing the polymer self-sealing hot-melt adhesive powder layer to fall off or off-edge defects, it is difficult to achieve the function and effect of the upgraded car tires without deflation

[0011] In order to solve the above-mentioned problems, relevant manufacturers and research institutes have worked hard to find a solution, but no suitable polymer self-sealing hot-melt adhesive powder has been found for a long time
