New tire sealing material composed of high-molecular polymers

Abstract

The invention discloses a new tire sealing material composed of high-molecular polymers, and belongs to the technical field of tires. The new tire sealing material comprises ethylene-vinyl acetate resin, polyisobutylene, polyethylene wax, bentonite nano-particles, rosin, ethyl cellulose, a rubber antioxidant 4020, silicone rubber particles and rubber oil. The new tire sealing material is mainly applied to meridian vacuum tires, is a new tire sealing material with the advantages of realization of rapid self gap (with the diameter being not greater than 10mm) filling without influencing the dynamic balance of wheels, no withering, no freezing, high reliability, good stability and good durability, and can be used in -60 ~ 100 DEG C environment for a long term. The above product contains various high-molecular polymers, and is in a liquid-solid concurrent gluing state in tires, can stably and uniformly adhere to the inner walls of the tires for a long term in order to realize zero leakage without influencing the dynamic balance of the wheels, so the new material innovatively breakthroughs materials in the prior art.

Description

technical field [0001] The invention belongs to the technical field of tires, and relates to a new self-replenishing material applied to vacuum tire sealing, in particular to a new tire sealing material composed of high molecular polymers. Background technique [0002] Automobiles and various motor vehicles have become one of the important symbols of modern civilization. During their use, tires are punctured by nails or sharp hard substances on the road surface to cause deflation, which often causes the vehicle to fail to operate normally. The earliest automatic tire sealant was applied in the US military wheeled vehicles in the 1920s and 1930s. The tires of military vehicles were filled with automatic tire sealant. It has a history of 80-90 years. The advantage of the automatic tire repair fluid in the prior art is that it can be repaired in 3 seconds without removing the tire; however, it also has many disadvantages: 1. It affects the dynamic balance of the wheel: when a c...

Problems solved by technology

The advantage of the automatic tire repair fluid in the prior art is that it can be repaired in 3 seconds without removing the tire; however, it also has many disadvantages: 1. It affects the dynamic balance of the wheel: when a can of automatic tire repair is used After the liquid is removed, 200ml-300ml of liquid remains on the inner bottom of the tire. This liquid makes the wheel run like an eccentric wheel, which not only increases the noise, but also reduces the stability, thus affecting the dynamic balance and belt when the wheel is running. There is a certain degree of traffic safety hazard

2. When the diameter of the tire wound is greater than 6mm, the automatic tire sealant does not work

3. There are also some inflatable tank type automatic tire sealant products, the ingredients of which can only temporarily inflate the flat tire and reduce leakage, until the vehicle is driven to the nearest repair station

4. Some tire sealant products will dry up inside the tire or freeze in cold weather, not only lose the sealing effect, but will damage the inner wall of the tire
