A kind of anti-puncture tread rubber and preparation method thereof

Abstract

The invention relates to an anti-puncture tread rubber and a preparation method thereof, belonging to the field of tire rubber. In the method of the present invention, the compound obtained after soaking the aramid fiber in the shear thickening solution is arranged on the inner surface of the tire tread as the anti-puncture layer, and the physical property that the anti-puncture layer will harden rapidly when it encounters a severe impact is used. , in order to achieve the purpose of preventing the tire from being punctured and causing a blowout. The thickness of the puncture-resistant layer in the present invention is a preferred thickness designed in consideration of factors such as puncture-resistant requirements and economic costs. The method has simple process and good effect, is widely applicable to various vehicle types and is suitable for large-scale production.

Description

technical field [0001] The invention belongs to the field of tire rubber and relates to a puncture-resistant tread rubber and a preparation method thereof. Background technique [0002] Road traffic safety is an issue that people attach great importance to now. When the vehicle is driving, the road conditions are uncertain, and there will inevitably be some sharp objects such as screws and stones on the road. If this happens when the vehicle is running at high speed, it is very easy to cause the tire to leak and cause a puncture. How to solve this potential safety hazard has also become a difficult problem for current tire manufacturers. [0003] There are few puncture-proof tires circulating on the market, and most of them are explosion-proof tires, that is, "run-flat tires". The ratio of the width to the tire) is larger, and the sidewall is very "fat". The reason why RSC run-flat tires will not collapse after deflation is mainly because of the thickened rubber sidewall...

AI Technical Summary

Problems solved by technology

In the case of flat tires, the vehicle can still travel 80 kilometers at a speed of 80 km / h; if the driver has no driving experience after a flat tire (most people do not), he may make wrong driving actions (such as rush brakes), which will lead to an irreparable loss of control of the vehicle

There are also some explosion-proof and leak-proof self-repairing tires on the market. The principle is to spray a polymer rubber on the inner wall of the tire tread (the inner surface of the part in contact with the ground) through professional equipment to form a protective layer with a thickness of about 5mm. It does not leak, pulling out the nails can automatically repair without repairing, but the nails still need to be pulled out after the follow-up process. If the nails are not pulled out and the car is running, it may still cause damage to other parts of the tire, and the cost of this kind of tire is high. mostly used in luxury cars
