AI Technical Summary
In the existing technology, the heat and oxygen aging resistance of natural rubber composite materials used in heavy truck leaf spring supports is not good enough, and it cannot simultaneously achieve reinforcement and anti-aging, which makes the material easy to be damaged in complex environments and affects the safety of the whole vehicle.
By combining modified covalent organic framework materials with carbon black, antioxidants, paraffin oil and vulcanizing agents, and utilizing the layered structure of the modified covalent organic framework and phosphotungstic acid modification, oxygen is blocked and free radicals are captured. Combined with the reinforcing properties of carbon black, an aging-resistant natural rubber composite material is prepared.
It slows down the aging process of natural rubber, improves the aging resistance and processing performance of the material, meets the usage requirements of leaf spring rubber bearings, reduces energy consumption and extends service life.
