Problems solved by technology

Existing polymer self-sealing polymer adhesives are difficult to meet this requirement, mostly due to poor adhesion of polymer self-sealing polymer adhesives and unreliable bonding with the inner wall crown surface of automobile tires, resulting in the polymer self-sealing polymer adhesive layer falling off or falling off. Defects, and it is difficult to achieve the function and effect of the upgraded car tires
[0006] 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 polymer has been found for a long time

Abstract

The invention relates to a preparation method of a polymer self-sealing polymer for a car tire. The self-sealing polymer is formed by a solid ingredient and a liquid ingredient, wherein the self-sealing polymer comprises the following main components in percentage by weight: 30%-38% of styrenic thermoplastic elastomer, 40%-45% of thermoplastic polymer resin of which the relative molecular weight is 200-2,000, 5%-15% of plasticizing softening component, 1%-2% of anti-ageing component, 0%-2% of catalytic prompting component and 0%-8% of filling heat-resistant component. The polymer self-sealing polymer provided by the invention is sprayed on the inner wall surface of the car tire in a hot melting manner, forms a uniform coating which is not smaller than 3.5mm thick, and can play the roles of sealing up, preventing stabbing and preventing bullets. The polymer self-sealing polymer has the advantages of being convenient to purchase raw material components, low in cost, good in elasticity, tensile property, self-filling air-tightness and the like, and a relatively effective technical support is provided for improving the usability of the product, and reducing the use cost of the user.

Description

technical field [0001] The invention relates to a polymer and a preparation method thereof, in particular to a preparation method of a polymer self-sealing polymer used 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. Tubeless car wheels have the advantages of good heat dissipation, softness, sealing and ride comfort, and long intervals between inflation and use. However, when tubeless car tires are punctured by sharp objects, the sharp objects remain in the car tire body, The high-pressure gas of the car tires 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 wheel will leak ...
