Problems solved by technology

The service life of traditional explosion-proof rubber is extremely short. After a period of use, it is easy to be thrown to the axis by the centripetal force of the tire, and due to factors such as high temperature on the road surface, it will flow and accumulate on the inner wall of the tire, not only failing to achieve the explosion-proof effect, but also is an additional risk factor

Abstract

The invention discloses tire burst-proof rubber. The tire burst-proof rubber comprises the following components in percentage by mass: 20-35% of a main polymer, 30-60% of tackifying resin, 10-25% of a diluting agent and 0.2-0.5% of an additive, and a special polystyrene-isoprene-styrene block copolymer is used as a main raw material. Through grafting modification, the rubber has 10 or more branched chains, and has efficient attaching performance, and through a special tackifier, cold resistance and heat resistance are improved, and a burst-proof function is effectively realized.

Description

technical field [0001] The invention relates to a tire explosion-proof rubber. Background technique [0002] Now the pneumatic tires of automobiles and electric bicycles will quickly leak and decompress after being punctured by sharp substances, which will cause great harm to people's safety. According to the statistics of the traffic management department, more than 70% of the highway traffic accidents in my country are caused by caused by a blowout. [0003] Based on the above reasons, there are currently many run-flat tires on the market, the principle of which is mostly to coat the inside of the tire with various adhesives to prevent sharp objects from piercing the tire and causing a blowout. The service life of traditional explosion-proof rubber is extremely short. After a period of use, it is easy to be thrown to the axis by the centripetal force of the tire, and due to factors such as high temperature on the road surface, it will flow and accumulate on the inner wall ...
