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

Abstract

The invention discloses a tire sealing composite new material containing BN-2 tackifying resin, and belongs to the technical field of tires. The tire sealing composite new material is characterized by being produced from BN-2 tackifying resin, NR natural rubber, a cross-linking agent BPO, nanoscale kaolin particles, tung oil, carbon fibers, a rubber anti deteriorant MB, butadiene styrene rubber particles, and methyl hydroxy silicone oil. The tire sealing composite new material is mainly applied in meridian vacuum tires, can quickly realize self complementing of nicks (diameters are smaller than or equal to 10mm), and is free from drying up, free from freezing, high in reliability, good in stability, and durable (the tire sealing composite new material can be used for a long time under the environment of minus 60 to 106 DEG C). The tire sealing composite new material disclosed by the invention contains varied high molecular polymers, is in a liquid-solid coexisting tacky state in the tires, and can be stably and uniformly adhered to the inner walls of the tires for a long term, so that the dynamic equilibrium of wheels is not influenced, and the tire sealing composite new material also has the effect of zero leakage, which are actually 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-replenishing material applied to vacuum tire sealing, in particular to a new tire sealing composite material containing BN-2 tackifying resin. 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: w...
