Abstract

The invention relates to the field of tire manufacturing, in particular to a sealant for a self-repairing tire, a preparation method of the sealant, and the self-repairing tire. The sealant is prepared from the following components in percentage by mass: 80 to 100 parts of butyl rubber; 0 to 20 parts of conjugated diene rubber; 5 to 70 parts of a reinforcing filler, which comprises 5 to 60 parts of carbon black and 0 to 30 parts of an inorganic filler; 50 to 500 parts of a liquid olefin compound; 0 to 50 parts of resin; and 2 to 20 parts of a vulcanizing agent. The mixture for the self-sealing tire has the effects that after the tire is punctured by a sharp object, the surface of the punctured object is coated with the mixture, and air in the tire is prevented from leaking quickly; when the tire is punctured by a sharp object or the sharp object is pulled out, the self-sealing mixture is used for repairing and sealing a hole formed in the tire by the sharp object, so gas in the tire is prevented from quickly leaking; and the self-sealing mixture allows the tire to be further used without repairing.

Description

technical field

[0001] The invention relates to the field of tire manufacture, in particular to a self-repair tire sealant, a preparation method thereof and a self-repair tire. Background technique

[0002] Now people pay more and more attention to environmental protection, and the requirements for gas emissions are getting higher and higher, especially the exhaust emissions of automobiles. When automakers produce new energy vehicles and gasoline vehicles, they reduce the weight of the car body to reduce vehicle exhaust emissions; at the same time, they also optimize the interior space of the car, improve the comfort of the car, and cancel the spare tire of the car.

[0003] During the operation of the pneumatic tires used by automobiles, due to foreign matter piercing the tires, the tires will leak, and the tire leaks will lead to unstable driving conditions, which requires immediate replacement of tires or temporary repairs to tires. In order to keep the vehicle in runnin...
