Novel tire sealing composite material containing 204 tackifying resin

Abstract

The invention discloses a new tire sealing composite material containing 204 tackifying resin. The invention belongs to the technical field of tires. The formula is characterized by: 204 tackifying resin, thermoplastic elastomer TPE, crosslinking agent mba, nano Composed of calcium carbonate particles, wood pitch, industrial starch, rubber antioxidant D, isoprene rubber particles, and ethyl silicone oil. The present invention is mainly used in radial vacuum tires, and is a fast self-filling gap (diameter less than or equal to 10mm), non-drying, non-freezing, high reliability, good stability, long-lasting and durable tire sealing composite new material (it can be used in -60°C-105°C environment for long-term use). The product of the present invention contains a variety of high molecular polymers, and its state in the tire is an adhesive state where liquid and solid coexist, and can adhere to the inner wall of the tire stably and evenly for a long time, thereby not affecting the dynamic balance of the wheel. The effect of zero leakage is achieved, which is indeed a revolutionary improvement compared with the prior art.

Description

technical field [0001] The invention belongs to the technical field of tires, and relates to a new self-repairing material for vacuum tire sealing, in particular to a new tire sealing compound material containing 204 tackifying resin. Background technique [0002] Automobiles and various motor vehicles have become one of the important symbols of modern civilization. During their use, the tires are punctured by nails or sharp hard substances on the road, causing deflation, and the phenomenon that the vehicle cannot run normally occurs frequently. The earliest automatic tire repair fluid was used in the U.S. military wheeled vehicles in the 1920s and 1930s. Automatic tire repair fluid was injected into the tires of military vehicles. It has a history of 80-90 years. The advantages of the automatic tire repair fluid in the prior art are: the tire can be repaired in 3 seconds without removing the tire; however, there are also many disadvantages: 1. It affects the dynamic balance...

AI Technical Summary

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
