Description

technical field [0001] The invention belongs to the technical field of polymer materials and relates to a covalent organic framework / styrene-butadiene rubber composite material. Background technique [0002] As the speed of high-speed trains continues to increase, the vibration and noise during the running process will also increase. On the one hand, the strong vibration during the running process will shorten the service life of the train components, and on the other hand, the noise generated during the running process will also increase. It will adversely affect the comfort of passengers and the surrounding environment, so it is necessary to carry out shock and noise reduction treatment for the train. [0003] Due to its unique viscoelasticity, the rubber material exhibits excellent damping performance. It mainly converts vibration energy into heat energy through the friction of molecular chains to achieve the purpose of shock absorption and noise reduction. However, tradi...
