Problems solved by technology

[0002] Rubber is a highly elastic polymer material with reversible deformation. It is elastic at room temperature. It can produce a large deformation under the action of a small external force, and it can return to its original shape after the external force is removed. During use, due to friction with other objects, resulting in The surface of the rubber is damaged or even loses its original performance, and the rubber is used for too long, and the aging speed becomes faster, especially the wear and erosion of the rubber pipeline, which will lead to the leakage of the internal transmission medium, and under extreme conditions, Environmental cracking resistance, high and low temperature resistance and weather resistance are poor, and it is not easy to degrade after being discarded and buried, polluting the environment
