Leakproof tire and preparation method thereof

Abstract

The invention relates to an anti-leakage tyre and a production method thereof, belonging to the technical field of vehicle tyres. The anti-leakage tyre comprises a tyre surface, a tyre shoulder and a coating layer in the tyre, and is characterized in that the coating layer in the tyre is formed by solidifying elastomer materials in a gel state, and the elastomer materials in a gel state are mainly formed by mixing following raw materials by weight: 50 to 70 portions of thermoplastic elastomer, 100 to 200 portions of softening oil, 30 to 60 portions of perduren powder and 0 to 10 portions of resin. The coating layer in the anti-leakage tyre cannot be softened to flow into a conglobation at higher ambient temperature or during high-speed driving of the tyre or the increase of heat accumulation temperature. The anti-leakage tyre can keep elasticity at lower temperature and has good self-sealing effect. When the tyre is broken by unctuous foreign matters at normal temperature, the tyre cannot leak and can be continuously used, thereby being safe and convenient.

Description

(1) Technical field [0001] The invention relates to a vehicle tire, in particular to an air-leakage-proof tire and a preparation method thereof. The invention belongs to the technical field of vehicle tires. (2) Background technology [0002] Most of the pneumatic tires of existing motor vehicles and non-motor vehicles do not have perfect safety guards, which can not effectively protect the tires from being punctured and the inner tires from being punctured. The better protection is that the inner tube adopts a thick rubber ferrule on a heavy foam type outer tire cover, but these methods are complicated in manufacturing process, affect the performance of the tire itself, and lack of practicability, so they cannot be widely used, so that the vehicles in motion are often caused by The outer tire was punctured by a sharp object, and then the inner tube was leaked, and the car had to be stopped for maintenance, and even an accident occurred. [0003] A kind of " run flat " tir...

AI Technical Summary

Problems solved by technology

[0005] 1. When the temperature of the tire is high or the tire is running at high speed, the heat storage temperature rises, the coating layer inside the tire will soften and flow into lumps, which will affect the sealing effect;

[0006] 2. At a lower temperature, the elastic colloid becomes hard and the self-sealing effect becomes poor. After the tire is punctured, the recovery ability becomes poor and air leakage occurs;

[0007] 3. At room temperature, after the tire is punctured by oily foreign matter, air leakage will also occur because the friction force becomes smaller

[0008] A tire leak will cause the tire to lose its dynamic and static balance, affecting driving safety
