Tire protectant and preparation method thereof

Abstract

The invention relates to a tire protectant. After the tire protectant which is ultimately prepared by adopting carboxyl cellulose, vegetable fibers, nanofiller, an antirust agent, an anti-aging agent, an antifreezing agent and water as raw materials and carrying out appropriate weight proportioning is injected into a tire, a thin protectant coating can be formed on the inner wall of a tire body by means of the centrifugal force of the rotating tire, and the protectant coating has the characteristics of good elasticity, high air tightness, good elongation, high stability, high tensile strength, high adhesive force and the like. When the automobile tire tread of the tire of an automobile wheel is pierced by a sharp object, the protectant coating of the inner wall of the tire can tightly close the piercing object under the effect of air pressure in the automobile wheel to automatically wrap and seal the piercing object, thus realizing self-healing, consequently, the function of preventing air in the tire of the automobile wheel from leaking out is achieved, and the driving safety of an automobile is enhanced.

Description

technical field [0001] The invention belongs to the technical field of tires, and in particular relates to a tire protective agent and a preparation method thereof. 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 performance, good ride comfort and long service life when inflated. The high-pressure gas of the tire 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 rapidly. Or two situations of rapid leakage, the risk of automobile accident is large, and the probability of car crash is high. [0003] Since...

AI Technical Summary

Problems solved by technology

Solid viscose-like materials such as isoprene rubber, butylene rubber or silicone rubber are used to make the bulletproof, leakproof, and puncture-resistant upgrade technology of automobile tires a step closer to the real market application, but there are many disadvantages and unfavorable factors: (1) Because 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; (2) the activity and anti-aging properties of this type of rubber cannot achieve substantial technological breakthroughs, and it is difficult to Long-term application in the harsh working environment of automobile wheels; (3) the solid viscose coating of isoprene rubber, butene rubber, and silicone rubber in automobile wheel tires. Excessive temperature rise of the tire causes local deformation of the coating inside the tire under the action of centrifugal force, which affects the dynamic balance of the car wheel
