Abstract

The invention discloses a tire sealing composite new material containing BRTR tackifying resin, and belongs to the technical field of tires. The tire sealing composite new material is characterized by being produced from BRTR tackifying resin, ethylene propylene rubber, a cross-linking agent tac, nanoscale silicon carbide particles, cottonseed oil, cullet fibers, a rubber antioxidant T501, butadiene rubber particles, and hydrogen-containing 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 110 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 BRTR 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...
